Linux Journal: Best Linux Distribution
by Peter Reutemann 14 Feb '18

14 Feb '18

'We started things off with Best Linux Distribution, and nearly 10,000 readers voted. The winner was Debian, with many commenting "As for servers, Debian is still the best" or similar. One to watch that is rising in the polls is Manjaro (7 percent), which is independently based on the Arch Linux. Manjaro is a favorite for Linux newcomers and is known for its user-friendliness and accessibility. And, now for the top three LJ winners: Debian (33 percent), openSUSE (12 percent), and Fedora (11 percent).' -- source: https://linux.slashdot.org/story/18/02/14/1850259 Does anyone want to give Manjaro a spin at the next meeting?

This was inevitable, really. Salon.com <https://arstechnica.com/information-technology/2018/02/salon-to-ad-blockers…> now asks you, when it notices you are running an ad-blocker, if you would like to contribute some CPU to running a cryptocurrency miner for them instead. What do you think: is it a fair trade? Is it a sustainable revenue model, at least better than doing the mining without asking your permission?

The Most Popular Linux Desktop Programs
by Peter Reutemann 14 Feb '18

14 Feb '18

'The most recent Linux Questions poll results are in. Steven J. Vaughan-Nichols, writing for ZDNet: LinuxQuestions, one of the largest internet Linux groups with 550,000 members, has just posted the results from its latest survey of desktop Linux users. In the always hotly-contested Linux desktop environment survey, the winner was the KDE Plasma Desktop. It was followed by the popular lightweight Xfce, Cinnamon, and GNOME. If you want to buy a computer with pre-installed Linux, the Linux Questions crew's favorite vendor by far was System76. Numerous other computer companies offer Linux on their PCs. These include both big names like Dell and dedicated small Linux shops such as ZaReason, Penguin Computing, and Emperor Linux. Many first choices weren't too surprising. For example, Linux users have long stayed loyal to the Firefox web browser, and they're still big fans. Firefox beat out Google Chrome by a five-to-one margin. And, as always, the VLC media player is far more popular than any other Linux media player. For email clients, Mozilla Thunderbird remains on top. That's a bit surprising given how Thunderbird's development has been stuck in neutral for some time now. When it comes to text editors, I was pleased to see vim -- my personal favorite -- win out over its perpetual rival, Emacs. In fact, nano and Kate both came ahead of Emacs.' -- source: https://linux.slashdot.org/story/18/02/13/1652238 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Active Browser Tabs Vs Active Browser Windows
by Lawrence D'Oliveiro 14 Feb '18

14 Feb '18

I have noticed some interesting behaviour with video playback on various websites, at least with Firefox. Videos on the NZ Herald website, for example, don’t start playing until the tab becomes the active one in the window. Also on YouTube, sometimes after an ad, there is a display inviting you to take part in some kind of survey. This displays for a fixed amount of time, but that time only accumulates while the tab is active -- make it inactive, and the time counter stops until it becomes active again. *But* ... the active tab is still considered to be active even if the window is not the frontmost one. This means if you want to do something else while waiting for a YouTube ad to finish playing (with the sound off, of course) and the extra display to disappear, you just have to do it in an entirely separate window.

Facebook is Pushing Its Data-tracking Onavo VPN Within Its Main Mobile App
by Peter Reutemann 14 Feb '18

14 Feb '18

'Onavo Protect, the VPN client from the data-security app maker acquired by Facebook back in 2013, has now popped up in the Facebook app itself, under the banner "Protect" in the navigation menu. Clicking through on "Protect" will redirect Facebook users to the "Onavo Protect -- VPN Security" app's listing on the App Store. We're currently seeing this option on iOS only, which may indicate it's more of a test than a full rollout here in the U.S. Marketing Onavo within Facebook itself could lead to a boost in users for the VPN app, which promises to warn users of malicious websites and keep information secure as you browse. But Facebook didn't buy Onavo for its security protections. Instead, Onavo's VPN allow Facebook to monitor user activity across apps, giving Facebook a big advantage in terms of spotting new trends across the larger mobile ecosystem. For example, Facebook gets an early heads up about apps that are becoming breakout hits; it can tell which are seeing slowing user growth; it sees which apps' new features appear to be resonating with their users, and much more. Further reading: Do Not, I Repeat, Do Not Download Onavo, Facebook's Vampiric VPN Service (Gizmodo).' -- source: https://tech.slashdot.org/story/18/02/13/2026211 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Camera Makers Still Showing Zero Interest In Protecting Users With Built-In Encryption
by Lawrence D'Oliveiro 13 Feb '18

13 Feb '18

From <https://www.techdirt.com/articles/20180204/07404639150/camera-makers-still-…>: The Freedom of the Press Foundation sent a letter to major camera manufacturers in December 2016, letting them know filmmakers and journalists would appreciate a little assistance keeping their data out of governments' hands. ... We've covered many cases where police officers have seized phones/cameras and deleted footage captured by bystanders. ... Unfortunately, it doesn't look like camera manufacturers are considering offering encryption. The issue still doesn't even appear to be on their radar, more than a year after the Freedom of the Press Foundation's letter -- signed by 150 photographers and filmmakers -- indicated plenty of customers wanted better protection for their cameras. ... If a government can search something, it will. Encryption may not thwart all searches, but it will at least impede the most questionable ones.

meeting next month
by Peter Reutemann 13 Feb '18

13 Feb '18

Hi everyone At the last meeting, Ian suggested to have cryptocurrencies (https://en.wikipedia.org/wiki/Cryptocurrency) as topic for our meeting next month. One aspect is the increasing amount of power that is consumed in order to mine "coins". The other interesting aspect introduced by, but not limit to, cryptocurrencies is the concept of the blockchain (https://en.wikipedia.org/wiki/Blockchain) an open, distributed ledger of transactions. Is there interest? Any volunteers to talk about something regarding this topic (history, current status, etc)?

VideoLAN VLC releases version 3.0 with HDR and 360-degree video
by Peter Reutemann 12 Feb '18

12 Feb '18

'The popular cross-platform, open-source video player VLC has received a significant update in 3.0, the first in what will be called the Vetinari branch. It adds support for HDR, including both 10-bit and 12-bit color and 360-degree video. This release version now also fully supports Chromecast streaming, a feature we first played with back in 2016. While VLC is open source, this part of it isn't; Tom's Hardware reports that VideoLAN explained it "used Google’s official closed-source SDK to build out the feature, which prevents it from releasing the source." [*] Other major added features include 3D audio support, audio passthrough for HD audio codecs, and support for browsing NAS drives. As always, a bunch of new codecs are supported too.' [*] 'Please note that Chromecast support in VLC 3.0 is fully open-source for all platforms! That’s the reason why it took us so long to ship as we completely reverse-engineered the entire thing. The closed-source component by Google can’t be used for legal reasons in VLC, isn’t compatible with Macs, Linux and Windows and supports a very limited set of codecs only. With our code, you can play basically anything VLC can decode on your Chromecast (as we transcode on-the-fly if needed).' -- source: https://arstechnica.com/gadgets/2018/02/videolan-vlc-releases-version-3-0-w… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Razer Doesn't Care About Linux'
by Peter Reutemann 12 Feb '18

12 Feb '18

'Razer is a vendor that makes high-end gaming hardware, including laptops, keyboards and mice. I opened a ticket with Razor a few days ago asking them if they wanted to support the LVFS project by uploading firmware and sharing the firmware update protocol used. I offered to upstream any example code they could share under a free license, or to write the code from scratch given enough specifications to do so. This is something I've done for other vendors, and doesn't take long as most vendor firmware updaters all do the same kind of thing; there are only so many ways to send a few kb of data to USB devices. The fwupd project provides high-level code for accessing USB devices, so yet-another-update-protocol is no big deal. I explained all about the LVFS, and the benefits it provided to a userbase that is normally happy to vote using their wallet to get hardware that's supported on the OS of their choice. I just received this note on the ticket, which was escalated appropriately: "I have discussed your offer with the dedicated team and we are thankful for your enthusiasm and for your good idea. I am afraid I have also to let you know that at this moment in time our support for software is only focused on Windows and Mac." The post, written by Richard -- who has long been a maintainer of GNOME Software, PackageKit, GNOME Packagekit, points out that Razer executive Min-Liang Tan last year invited Linux enthusiasts to suggest ideas to help the company make the best notebook that supports Linux.' -- source: https://linux.slashdot.org/story/18/02/12/0722235 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How the First Open Source Software and Hardware Satellite UPSat Was Built
by Peter Reutemann 11 Feb '18

11 Feb '18

'UPSat is the first open source -- both hardware and software -- satellite to have ever been launched in orbit. Pierros Papadeas, the Director of Operations for Libre Space Foundation, which helped build the UPSat, talked about the project at FOSDEM, a non-commercial, volunteer-organized European event focused on free and open-source software development. You can watch the talk here; and read an interview of him with folks at FOSDEM ahead of the talk here. Two excerpts from the interview: Q: What challenges did you encounter while designing, building, testing and eventually launching UPSat in orbit? PP: The challenges where numerous, starting with the financial ones. Lack of appropriate funding led us to invest heavily in the project (through Libre Space Foundation funds) to ensure its successful completion. Countless volunteer participation was also key to the success. On the technical side, with minimal documentation and knowledge sharing around space projects we had to re-invent the wheel and discover many procedures and practices in a really short time-frame (6 months - unheard for a space mission). Lack of tools and equipment made our building process a creative exploration as we had to figure out ways to achieve specific tasks resorting to purpose-built projects in our local lab (hackerspace.gr). Testing and verification facilities where also a challenge mainly as we had to undergo much more extensive tests than other missions, having none of our components already "flight proven". Again creativity and countless hours of negotiations and documentation got us to the final delivery point. Launching UPSat in orbit was secured once the delivery happened, but as any typical space mission it came with long delays and timeline push-backs. Q: What do you hope to accomplish by giving this talk? What do you expect? Through this talk we would like to raise awareness for open source initiatives in space, and inspire open source technologists (engineers, programmers, analysts, makers) to engage in an open source project. We would also love to gather feedback and ideas on next steps and provide contribution opportunities for interested parties.' -- source: https://news.slashdot.org/story/18/02/11/2139203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

EFF Founder John Perry Barlow Has Died At Age 70
by Peter Reutemann 08 Feb '18

08 Feb '18

'The Electronic Frontier Foundation reports that its founder, John Perry Barlow, has passed away quietly in his sleep this morning. He was 70 years old. From the report: It is no exaggeration to say that major parts of the Internet we all know and love today exist and thrive because of Barlow's vision and leadership. He always saw the Internet as a fundamental place of freedom, where voices long silenced can find an audience and people can connect with others regardless of physical distance. Barlow was sometimes held up as a straw man for a kind of naive techno-utopianism that believed that the Internet could solve all of humanity's problems without causing any more. As someone who spent the past 27 years working with him at EFF, I can say that nothing could be further from the truth. Barlow knew that new technology could create and empower evil as much as it could create and empower good. He made a conscious decision to focus on the latter: "I knew it's also true that a good way to invent the future is to predict it. So I predicted Utopia, hoping to give Liberty a running start before the laws of Moore and Metcalfe delivered up what Ed Snowden now correctly calls 'turn-key totalitarianism.'" Barlow's lasting legacy is that he devoted his life to making the Internet into "a world that all may enter without privilege or prejudice accorded by race, economic power, military force, or station of birth... a world where anyone, anywhere may express his or her beliefs, no matter how singular, without fear of being coerced into silence or conformity."' -- source: https://politics.slashdot.org/story/18/02/07/234213 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Insurance Companies Recommending Computer Gear?

I’m in favour (up to a point) of charging according to assessed risk, but basing it on specific brand names leaves them open to accusations of conflict of interest. Better it be done according to adherence to published nonproprietary standards, such as PCI-DSS, for example.

New IoT botnet offers DDoSes of once-unimaginable sizes for $20
by Peter Reutemann 02 Feb '18

02 Feb '18

'Organizers of a new botnet made up of infected home and small office routers are brazenly selling denial-of-service attacks of once unimaginable volumes for just $20 per target. Calling itself Los Calvos de San Calvicie, the group is advertising several services on this site. Among the services are distributed denial-of-service attacks of 290 to 300 gigabits per second for $20 each. While a third the size of some of the biggest recorded attacks, 290Gbps is still enough to bring most sites down unless they seek DDoS mitigation services, which in many cases cost considerable amounts of money. Just five years ago, 300Gbps was considered enough volume to shut down the Internet's core infrastructure. Los Calvos de San Calvicie members have been spotted assembling a botnet in recent days that very possibly has the firepower required to deliver the potent attacks promised. According to Pascal Geenens, a researcher at security firm Radware, the group is building the botnet by exploiting two vulnerabilities: one in RealTek routers running out-of-date firmware and the other in the Huawei HG532 router, where a patch released in December has yet to be installed by many users. Both vulnerabilities are also exploited by a different Internet-of-things botnet known as Satori.' -- source: https://arstechnica.com/information-technology/2018/02/for-sale-ddoses-guar… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Releases Skype As a Snap For Linux
by Peter Reutemann 01 Feb '18

'While Microsoft has long been viewed as an enemy of the Linux community -- and it still is by some -- the company has actually transformed into an open source champion. One of Microsoft's biggest Linux contributions, however, is Skype -- the wildly popular communication software. By offering that program to desktop Linux users, Microsoft enables them to easily communicate with friends and family that aren't on Linux, thanks to its cross-platform support. Today, Microsoft further embraces Linux by releasing Skype as a Snap. This comes after two other very popular apps became available in Snap form -- Spotify and Slack. "Skype is used by millions of users globally to make free video and voice calls, send files, video and instant messages and to share both special occasions and everyday moments with the people who matter most. Skype has turned to snaps to ensure its users on Linux, are automatically delivered to its latest versionupon release. And with snaps' roll-back feature, whereby applications can revert back to the previous working version in the event of a bug, Skype's developers can ensure a seamless user experience," says Canonical.' -- source: https://linux.slashdot.org/story/18/02/01/1644250 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'LibreOffice 6.0 comes two and a half years after the LibreOffice 5.x series, and it's the biggest release of the open-source and cross-platform office suite so far. It introduces a revamped design with new table styles, improved Notebookbars, new gradients, new Elementary icons, menu and toolbar improvements, and updated motif/splash screen. LibreOffice 6.0 offers superior interoperability with Microsoft Office documents and compatibility with the EPUB3 format by allowing users to export ODT files to EPUB3. It also lets you import your AbiWord, Microsoft Publisher, PageMaker, and QuarkXPress documents and templates thanks to the implementation of a set of new open-source libraries contributed by the Document Liberation project. Many great improvements were made to the OOXML and ODF filters, as well as in the EMF+, Adobe Freehand, Microsoft Visio, Adobe Pagemaker, FictionBook, Apple Keynote, Pages, and Numbers, as well as Quattro Pro import functionality, and to the XHTML export. LibreOffice Online received numerous improvements as well in this major release of LibreOffice.' -- source: https://news.slashdot.org/story/18/01/31/1422245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Samsung Surpasses Intel To Become the World's Largest Chipmaker
by Peter Reutemann 31 Jan '18

31 Jan '18

'Samsung Electronics just knocked Intel off its perch as the world's biggest chipmaker by revenue, a spot the U.S. company has held since 1992. From a report: On Tuesday, Samsung reported 2017 chip sales of $69 billion, blowing past Intel's $63 billion from last year. The switch underlines how Samsung has transformed itself from a maker of cheap televisions into a pervasive supplier of key components in smartphones and other modern computing devices. It's also a testament to the growth of memory chips, Samsung's main market. Intel, whose processors are the heart of about 90 percent of the world's computers, didn't have a bad year. Sales grew 6 percent. Success in computers is no longer enough, though. Memory chips, a market Intel only recently got back into, are now crucial parts of smartphones, which easily outsell PCs these days. Memory chips are also finding their way into a range of new devices such as cars. One of the ironies of Samsungâ(TM)s success in memory is that itâ(TM)s a business Intel created in the 1960s.' -- source: https://slashdot.org/story/18/01/31/1516212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Chrome To Feature Built-In Image Lazy Loading
by Peter Reutemann 31 Jan '18

'Future versions of Google Chrome will feature built-in support for lazy loading, a mechanism to defer the loading of images and iframes if they are not visible on the user's screen at load time. This system will first ship with Chrome for Android and Google doesn't rule out adding it to desktop versions if tests go as planned. The feature is called Blink LazyLoad, and as the name hints, it will implement the principle of "lazy loading" inside Chrome itself. Google engineers reported page load speed improvements varying from 18% to 35%, depending on the underlying network. Other browser makers have been notified of the Chrome team's plan, but none have provided input if they plan to implement a similar feature. Compared to most JS-based lazy loading scripts that only target images, Google implementation will also target iframes.' -- source: https://tech.slashdot.org/story/18/01/31/180234 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

MPEG Founder Says the MPEG Business Model Is Broken
by Peter Reutemann 30 Jan '18

30 Jan '18

'Leonardo Chiariglione, the founder and chairman of MPEG, argues on his blog that the current MPEG business model is broken. He writes, "Thanks to [MPEG's] 'business model' that can be simply described as: produce standards having the best performance as a goal, irrespective of the IPR involved. Because MPEG standards are the best in the market and have an international standard status, manufacturers/service providers get a global market of digital media products, services and applications, and end users can seamless communicate with billions of people and access millions of services. Patent holders who allow use of their patents get hefty royalties with which they can develop new technologies for the next generation of MPEG standards. A virtuous cycle everybody benefits from." But, he argues, the MPEG model is now in crisis because the forthcoming AV1 video format from the Alliance for Open Media means that "everybody realizes that the old MPEG business model is broke, all the investments (collectively hundreds of millions USD) made by the industry for the new video codec [HEVC] will go up in smoke and AOM's royalty free model will spread to other business segments as well." Chiariglione goes on to explain what can be done: "The first action is to introduce what I call 'fractional options.' ISO envisages two forms of licensing: Option 1, i.e. royalty free and Option 2, i.e. FRAND, which is taken to mean 'with undetermined license.' We could introduce fractional options in the sense that a proposer could indicate that the technology be assigned to a specifically identified profile with an 'industry license' (defined outside MPEG) that does not contain monetary values. For instance, one such license could be 'no charge' (i.e. Option 1), another could be targeted to the OTT market etc." "The second action, not meant to be alternative to the first, is to streamline the MPEG standard development process. Within this a first goal is to develop coding tools with 'clear ownership,' unlike today's tools which are often the result of contributions with possibly very different weights. A second goal is not to define profiles in MPEG. A third goal could be to embed in the standard the capability to switch coding tools on and off."' -- source: https://news.slashdot.org/story/18/01/30/0419222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Remember the alert about the incoming missile in Hawaii that turned out to be nonsense? This <https://arstechnica.com/information-technology/2018/01/the-interface-to-sen…> is apparently what the user interface looks like for the system that sends out both test and genuine alerts. It looks like a web page with a random assortment of links. Just off the top of my head, not claiming to be a UI expert here, but I would have a big title across the top of the screen saying either “TEST MODE” or “LIVE MODE” (the latter red, and blinking). Then have a single set of options below, appropriate to the active mode. Even go one better, and do what Japanese railway locomotive drivers do as they see signs at the side of the track: say out loud what the signs mean, before taking appropriate action.

The SCO Vs IBM Zombie Shambles On
by Peter Reutemann 29 Jan '18

29 Jan '18

'At the end of last October, the 10th Circuit issued an opinion overturning the lower court's summary judgement in favor of IBM on one of SCO's claims, sending it back to the lower court for trial. Shortly thereafter, IBM filed for a re-hearing en banc. On January 2nd, the 10th circuit essentially denied IBM's request, issuing a slightly revised opinion with the same conclusions and result. The charge being reheard accuses IBM of "stealing and improperly using [SCO's] source code to strengthen its own operating system, thereby committing the tort of unfair competition by means of misappropriation" -- though that charged is based on an implied duty that SCO says IBM incurred by entering into a development relationship with SCO. "SCO believes that IBM merely pretended to go along with the arrangement in order to gain access to Santa Cruz's coveted source code." The court's 46-page document adds that "We are now almost fifteen years into this litigation."' -- source: https://yro.slashdot.org/story/18/01/29/0213203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Told Chinese Firms of Meltdown Flaws Before the US Government
by Peter Reutemann 29 Jan '18

29 Jan '18

'According to The Wall Street Journal, Intel initially told a handful of customers about the Meltdown and Spectre vulnerabilities, including Chinese tech companies like Alibaba and Lenovo, before the U.S. government. As a result, the Chinese government could have theoretically exploited the holes to intercept data before patches were available. Engadget reports: An Intel spokesman wouldn't detail who the company had informed, but said that the company couldn't notify everyone (including U.S. officials) in time because Meltdown and Spectre had been revealed early. Lenovo said the information was protected by a non-disclosure agreement. Alibaba has suggested that any accusations of sharing info with the Chinese government was "speculative and baseless," but this doesn't rule out officials intercepting details without Alibaba's knowledge. There's no immediate evidence to suggest that China has taken advantage of the flaws, but that's not the point -- it's that the U.S. government could have helped coordinate disclosures to ensure that enough companies had fixes in place.

Are the BSDs Dying? Some Security Researchers Think So
by Peter Reutemann 26 Jan '18

26 Jan '18

'The BSDs have lost the battle for mindshare to Linux, and that may well bode ill for the future sustainability of the BSDs as viable, secure operating systems, writes CSO's JM Porup. The reason why is a familiar refrain: more eyeballs mean more secure code.

Ubuntu 18.04 LTS Will Default To The X.Org Stack, Not Wayland
by Peter Reutemann 26 Jan '18

26 Jan '18

'Five years after their original goal to ship Ubuntu with Wayland, Ubuntu 17.10 transitioned to using the Wayland display system by default as part of their transition to GNOME Shell as the default desktop. But with the upcoming Ubuntu 18.04 LTS release, Canonical has decided to transition back to the X.Org Server. Their reasoning for moving to an X.Org Server by default is better support for screen sharing, remote desktop, and better recovery from crashes. But for those interested the Wayland session will still be available as a log-in option.' -- source: https://news.slashdot.org/story/18/01/26/1437212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Senator Asks FBI Director To Justify His 'Ill-Informed' Policy Proposal For Encryption
by Peter Reutemann 26 Jan '18

26 Jan '18

'In a speech earlier this month, FBI Director Christopher Wray said the inability of law enforcement authorities to access data from electronic devices due to powerful encryption is an "urgent public safety issue." He proposed that Silicon Valley companies should add a backdoor to their encryption so that they could both "provide data security and permit lawful access with a court order." One person is not amused by Wray's proposal. Senator Ron Wyden criticized Wray on Thursday for not consulting him before going public with the proposal for encryption. Wyden said today, via Gizmodo: Your stated position parrots the same debunked arguments espoused by your predecessors, all of whom ignored the widespread and vocal consensus of cryptographers. For years, these experts have repeatedly stated that what you are asking for is not, in fact, possible. Building secure software is extremely difficult, and vulnerabilities are often introduced inadvertently in the design process. Eliminating these vulnerabilities is a mammoth task, and experts are unified in their opinion that introducing deliberate vulnerabilities would likely create catastrophic unintended consequences that could debilitate software functionality and security entirely. [...] I would like to learn more about how you arrived at and justify this ill-informed policy proposal. Please provide me with a list of the cryptographers with whom you've personally discussed this topic since our July 2017 meeting and specifically identify those experts who advised you that companies can feasibly design government access features into their products without weakening cybersecurity. Please provide this information by February 23, 2018.' -- source: https://yro.slashdot.org/story/18/01/25/161245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New Unit Of Time: The “Flick”
by Lawrence D'Oliveiro 26 Jan '18

26 Jan '18

Oculus is proposing a new unit for measuring time for audio/video/VR purposes: it is 1/705,600,000 of a second. This denominator was chosen to have sufficient integer factors to allow it to exactly represent various common frame/sample rates as whole numbers of flicks (which cannot be done with the usual SI divisions). And also, from the looks of it, possible future higher multiples of those rates. <https://arstechnica.com/gaming/2018/01/oculus-creates-a-new-open-source-uni…>

From <http://www.theregister.co.uk/2018/01/24/death_notice_for_moores_law/>: The computer science behind microprocessor design has therefore found itself making a rapid U-turn as it learns that its optimisation techniques can be weaponised. ... Hammered by the finance of physics and the weaponisation of optimisation, Moore’s Law has hit the wall, bounced off - and reversed direction. We’re driving backwards now: all things IT will become slower, harder and more expensive. Actually economics probably had more to do with it than physics, as PC sales have been slowing over the past decade.

City of Barcelona Dumps Windows For Linux and Open Source Software
by Peter Reutemann 24 Jan '18

24 Jan '18

'The City of Barcelona is migrating its computer systems away from the Windows platform, reports the Spanish newspaper El País. The City's strategy is first to replace all user applications with open-source alternatives, until the underlying Windows operating system is the only proprietary software remaining. In a final step, the operating system will be replaced with Linux... According to Francesca Bria, the Commissioner of Technology and Digital Innovation at the City Council, the transition will be completed before the current administration's mandate ends in spring 2019. For starters, the Outlook mail client and Exchange Server will be replaced with Open-Xchange. In a similar fashion, Internet Explorer and Office will be replaced with Firefox and LibreOffice, respectively. The Linux distribution eventually used will probably be Ubuntu, since the City of Barcelona is already running 1,000 Ubuntu-based desktops as part of a pilot... Barcelona is the first municipality to have joined the European campaign 'Public Money, Public Code'. This campaign is an initiative of the Free Software Foundation Europe (FSFE) and revolves around an open letter advocating that publicly funded software should be free. Currently, this call to public agencies is supported by more than 100 organisations and almost 15,000 individuals. With the new open-source strategy, Barcelona's City Council aims to avoid spending large amounts of money on licence-based software and to reduce its dependence on proprietary suppliers through contracts that in some cases have been closed for decades.' -- source: https://linux.slashdot.org/story/18/01/15/0415219 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox 58 Gets Graphics Speed Boost, Web App Abilities
by Peter Reutemann 23 Jan '18

23 Jan '18

'Mozilla released on Tuesday a new version of its Firefox Quantum browser, boosting its graphics speed and improving a couple of new technologies designed to make the web more powerful. From a report: The browser, version 58, is the first major update since Mozilla's recovery plan hit full stride in November with the debut of Firefox Quantum. Speed is of the essence in Mozilla's recovery plan, and Firefox 58 does better than its predecessor in some graphics tasks by splitting work better across the multiple processor cores that computer chips have these days. The result should be scrolling that's smooth, uninterrupted by the stuttering that in computing circles goes by the disparaging term "jank." [...] Firefox 58 helps with two new web technologies. One, called WebAssembly, provides for dramatically faster web apps. Firefox 58 can get WebAssembly software running faster so you don't have to twiddle your thumbs waiting as long after clicking a link. Another is progressive web apps (PWAs), an initiative that came out of Google to help make the web a better match for the apps we all drop on our phones.' -- source: https://tech.slashdot.org/story/18/01/23/150206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Fake Ads Redirecting To Malicious Software Installers
by Lawrence D'Oliveiro 23 Jan '18

23 Jan '18

Seems a consortium of fake ad companies has been built up, cultivating relationships with legitimate ad platforms, and then carefully inserting forced redirects in a proportion of the ads they serve, to trick unwitting viewers into installing malware on their machines. Various checks are first applied, to try to ensure that the machines being redirected don’t happen to be run by security researchers, for example. Each member of the consortium is activated for serving this malware in turn; then when it is exposed, it is abandoned and the operators move on to the next one. <https://arstechnica.com/information-technology/2018/01/malvertising-factory…>

Has the Decades-Old Floating Point Error Problem Been Solved?
by Peter Reutemann 22 Jan '18

22 Jan '18

'Wednesday a company called Bounded Floating Point announced a "breakthrough patent in processor design, which allows representation of real numbers accurate to the last digit for the first time in computer history. This bounded floating point system is a game changer for the computing industry, particularly for computationally intensive functions such as weather prediction, GPS, and autonomous vehicles," said the inventor, Alan Jorgensen, PhD. "By using this system, it is possible to guarantee that the display of floating point values is accurate to plus or minus one in the last digit..." The innovative bounded floating point system computes two limits (or bounds) that contain the represented real number. These bounds are carried through successive calculations. When the calculated result is no longer sufficiently accurate the result is so marked, as are all further calculations made using that value. It is fail-safe and performs in real time. Jorgensen is described as a cyber bounty hunter and part time instructor at the University of Nevada, Las Vegas teaching computer science to non-computer science students. In November he received US Patent number 9,817,662 -- "Apparatus for calculating and retaining a bound on error during floating point operations and methods thereof." But in a followup, HPCwire reports: After this article was published, a number of readers raised concerns about the originality of Jorgensen's techniques, noting the existence of prior art going back years. Specifically, there is precedent in John Gustafson's work on unums and interval arithmetic both at Sun and in his 2015 book, The End of Error, which was published 19 months before Jorgensen's patent application was filed. We regret the omission of this information from the original article.' -- source: https://science.slashdot.org/story/18/01/21/0157230 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google’s Fuchsia OS on the Pixelbook: It works! It actually works!
by Peter Reutemann 21 Jan '18

21 Jan '18

'Google currently has two OSes on the market: Android and Chrome OS. The company is never one to leave a successful product alone in the marketplace, though, so it's also developing a third operating system called "Fuchsia." When we last checked in on the experimental OS in May 2017, calling it an "OS" was a bit of a stretch. We only got the system UI up and running on top of Android, where it then functioned like an app. The UI offered a neat multi-window system, but mostly it was just a bunch of placeholder graphics. Nothing worked. It has been hard to check in on Fuchsia since. The Fuchsia system UI, which was written with a cross-platform SDK called "Flutter," quickly shut down the Android (and iOS) compatible builds. Fuchsia has a Vulkan-based graphics stack, and no emulator supports the new-ish graphics API. The only way to get Fuchsia up and running again was with actual hardware, and the only supported devices were Intel NUC PCs from 2015 and the Acer Switch Alpha 12 laptop. So after the recent news that the Fuchsia team picked the Chrome OS-powered Google Pixelbook as a supported device, we jumped at the chance to get it up and running. And after a little elbow grease, it actually booted. Now, we're not just running the system UI on top of Android like last time, we're running Fuchsia directly on a piece of hardware! This means it's finally time for a deep dive on what Fuchsia looks like in early 2018. Our usual in-development OS testing caveats apply: Fuchsia only started development in 2016 and probably has several years of development time ahead of it. Everything can—and probably will—change between now and release (if a release ever even happens). Google won't even officially acknowledge the OS exists—Fuchsia is a bunch of code sitting on fuchsia.googlesource.com.' -- source: https://arstechnica.com/gadgets/2018/01/googles-fuchsia-os-on-the-pixelbook… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

NHoS/NHSBuntu Gives Up After NHS Trademark Bullying
by Lawrence D'Oliveiro 18 Jan '18

18 Jan '18

The small team of volunteers behind the NHoS project (formerly NHSBuntu) are giving up. They wanted to offer an alternative to the current NHS smartcard implementation system, currently running on Windows, using open-source software. First they rebranded from “NHSBuntu” to “NHoS” (along with “overhauling the previous tooling and branding”), which they thought would address trademark concents from the NHS. But now it seems even this name is considered unacceptable. One of the developers, Marcus Baw, ... said openhealthhub had numerous conversations that had led to "several cancelled-at-the-last minute meetings" with NHS England (NHSE) CIO Will Smart and Paul Rice, head of technology strategy in the Digital Health team. Baw alleged the pair "(unbeknown to us) were also duplicitously negotiating with Microsoft about a new NHS Enterprise Wide Agreement". He added: "In fact I now strongly suspect that the reason we were getting any engagement at all at these levels was in order to strength NHSE negotiating position with Microsoft, by being able to say to M$ 'There is a competitor, we are meeting with them next week'." <http://www.theregister.co.uk/2018/01/18/nhs_thanks_for_all_the_free_work_li…>

Hackers can’t dig into latest Xiaomi phone due to GPL violations

'Yet another Android OEM is dragging its feet with its GPL compliance. This time, it's Xiaomi with the Mi A1 Android One device, which still hasn't seen a kernel source code release. Android vendors are required to release their kernel sources thanks to the Linux kernel's GPLv2 licensing. The Mi A1 has been out for about three months now, and there's still no source code release on Xiaomi's official github account. Unfortunately, GPL non-compliance is par for the course in the world of Android. Budget SoC company MediaTek once tried charging users for access to GPL'd code. Motorola under Lenovo has been regularly accused of violating the GPL and releasing incomplete sources or sources that differ from the kernel shipping on devices. Unsurprisingly, the majority of these alleged GPL violators are from China, which often plays fast and loose with IP law. Android developers use the source code to create custom kernels that tweak the way a device works, allowing for overclocking, better battery life, or control over the CPU governor. One of the largest custom kernel developers, Francisco Franco, has started a public Twitter campaign to encourage Xiaomi to comply with the GPL.' -- source: https://arstechnica.com/gadgets/2018/01/xiaomi-is-dragging-its-feet-on-the-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Found: New Android malware with never-before-seen spying capabilities
by Peter Reutemann 17 Jan '18

17 Jan '18

'Last year, researchers found what at the time was quite possibly the world's most sophisticated espionage app ever written for the Android mobile operating system. Now, in a discovery that underscores the growing arms race among competing malware developers, researchers have uncovered a new Android spying platform that includes location-based audio recording and other features that have never been seen in the wild before. According to a report published Tuesday by antivirus provider Kaspersky Lab, "Skygofree" is most likely an offensive security product sold by an Italy-based IT company that markets various surveillance wares. With 48 different commands in its latest version, the malware has undergone continuous development since its creation in late 2014. It relies on five separate exploits to gain privileged root access that allows it to bypass key Android security measures. Skygofree is capable of taking pictures, capturing video, and seizing call records, text messages, geolocation data, calendar events, and business-related information stored in device memory. Skygofree also includes the ability to automatically record conversations and noise when an infected device enters a location specified by the person operating the malware. Another never-before-seen feature is the ability to steal WhatsApp messages by abusing the Android Accessibility Service that's designed to help users who have disabilities or who may temporarily be unable to fully interact with a device. A third new feature: the ability to connect infected devices to Wi-Fi networks controlled by attackers. Skygofree also includes other advanced features, including a reverse shell that gives malware operators better remote control of infected devices. The malware also comes with a variety of Windows components that provide among other things a reverse shell, a keylogger, and a mechanism for recording Skype conversations' -- source: https://arstechnica.com/information-technology/2018/01/found-new-android-ma… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Phrase Of The Week: “Foveated Rendering”
by Lawrence D'Oliveiro 16 Jan '18

16 Jan '18

<http://www.theregister.co.uk/2018/01/16/human_limits_of_vr_and_ar/>: By some estimates, given a field of view of 180 degrees, around 74 gigabytes of visual data are available to us each second, but only around 125 megabytes are ultimately processed ... Much of the rest is chucked away before it even gets to the optic nerve. But trying to minimize the rendering workload by concentrating on the fovea (the most detail-sensitive part of the eye, the little spot where the image falls when you “look at” something) is not so simple, given the quirks of how our visual perception actually works. Computer graphics doyen Alvy Ray Smith is reputed to have said “reality is 80 million polygons per second”. I think we can achieve that now, but the pixel rate considered acceptable on a conventional monitor is peanuts compared to that required for VR.

20 Years Later, Has Open Source Changed the World?
by Peter Reutemann 15 Jan '18

15 Jan '18

'"Most code remains closed and proprietary, even though open source now dominates enterprise platforms," notes Matt Asay, former COO at Canonical (and an emeritus board member of the Open Source Initiative). "How can that be?" he asks, in an essay noting it's been almost 20 years since the launch of the Open Source Initiative, arguing that so far open source "hasn't changed the world as promised." [T]he reason most software remains locked up within the four walls of enterprise firewalls is that it's too costly with too small of an ROI to justify open-sourcing it. At least, that's the perception. Such a perception is impossible to break without walking the open source path, which companies are unwilling to walk without upfront proof. See the problem? This chicken-and-egg conundrum is starting to resolve itself, thanks to the forward-looking efforts of Google, Facebook, Amazon, and other web giants that are demonstrating the value of open-sourcing code. Although it's unlikely that a State Farm or Chevron will ever participate in the same way as a Microsoft, we are starting to see companies like Bloomberg and Capital One get involved in open source in ways they never would have considered back when the term "open source" was coined in 1997, much less in 2007. It's a start. Let's also not forget that although we have seen companies use more open source code over the past 20 years, the biggest win for open source since its inception is how it has changed the narrative of how innovation happens in software. We're starting to believe, and for good reason, that the best, most innovative software is open source. The article strikes a hopeful note. "We're now comfortable with the idea that software can, and maybe should, be open source without the world ending. The actual opening of that source, however, is something to tackle in the next 20 years.' -- source: https://news.slashdot.org/story/18/01/14/1627207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Germany Ban On Online Hate Speech Triggers Debate
by Lawrence D'Oliveiro 10 Jan '18

10 Jan '18

A new law has come into effect in Germany whereby companies like Facebook and Twitter face multi-million-euro fines if they don’t block their users from expressing “hate speech” <http://www.aljazeera.com/news/2018/01/germany-ban-online-hate-speech-trigge…>. Trouble is, this law seems to be a bit of a blunt axe: on the one hand it led to the temporary suspension of the Twitter account of the deputy leader of the far-right AfD party, Beatrix von Storch. But also caught up in the net was the account of the satirical “Titanic” magazine, after it parodied a phrase used by von Storch. Then again, if you are seen to clamp down too hard on particular points of view, that gives political ammunition to those who claim they are being censored...

Re-Assembling Shredded Stasi Records
by Lawrence D'Oliveiro 09 Jan '18

09 Jan '18

During the last days of the German Democratic Republic (a.k.a. East Germany), the Stasi secret police tried to destroy the more incriminating records they had been keeping on their own citizens. They were only partially successful. And even then, there has been an ongoing project to reassemble those torn-up pieces of paper, by scanning them and doing pattern-recognition to match up the image pieces. Seems the easiest ones are fairly manageable, but now they are getting to smaller fragments, which are proving more of a challenge. <https://www.techdirt.com/articles/20180105/07120838936/stasis-tiny-torn-up-…>

Another Fork Takes Over The Original Project
by Lawrence D'Oliveiro 08 Jan '18

08 Jan '18

Open-source software projects can fork for various reasons. Sometimes a bunch of developers want to go in a different direction. Other times the original project appears to be languishing, but those in charge are reluctant to give up control. Sometimes the forks peter out, other times they coexist happily (or unhappily) with the original project, occasionally they even absorb the original project. This <http://www.theregister.co.uk/2018/01/08/lede_and_openwrt_merge/> seems to be one of the latter cases: the LEDE fork of OpenWRT is merging back in, but the merger will be “governed under the rules of the LEDE project”.

Can You Install Linux On a 1993 PC?
by Peter Reutemann 07 Jan '18

07 Jan '18

'The oldest x86 CPU that the Linux kernel supports today is theoretically the 486. However is this theory actually true in practice? I decided to put this theory to the test in my project. His site describes installing Gentoo Linux on an "ancient" IBM PS/1 Consultant 2133 19C (released in 1993), with 64MB SIMM-72 RAM. (Though to speed things up, he compiled that minimal version of Gentoo on a modern Thinkpad T430 released in 2012.) "Due to the age of the PC, the BIOS only supports booting from the floppy drive or internal HDD," so there was also some disk partitioning and kernel configuration. ("Must disable 64-bit kernel for obvious reasons!") A half-hour video shows that it takes almost 11 minutes just to boot up -- and five and a half minutes to shut down. "Despite the many roadblocks I faced, I was impressed by the level of support Linux has for ancient hardware like this." And there's one more added bonus. "Given the age of the 486 (1989 technology), it does not support branch prediction... Ironically this makes it safe from the Meltdown and Spectre attacks."' -- source: https://linux.slashdot.org/story/18/01/07/228222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Can We Replace Intel x86 With an Open Source Chip?
by Peter Reutemann 07 Jan '18

07 Jan '18

'Perhaps the Meltdown and Spectre bugs are the impetus for making long-overdue changes to the core DNA of the semiconductor industry and how chip architectures are designed... Linux (and other related FOSS tech that forms the overall stack) is now a mainstream operating system that forms the basis of public cloud infrastructure and the foundational software technology in mobile and Internet of Things (IoT)... We need to develop a modern equivalent of an OpenSPARC that any processor foundry can build upon without licensing of IP, in order to drive down the costs of building microprocessors at immense scale for the cloud, for mobile and the IoT. It makes the $200 smartphone as well as hyperscale datacenter lifecycle management that much more viable and cost-effective. Just as Linux and open source transformed how we view operating systems and application software, we need the equivalent for microprocessors in order to move out of the private datacenter rife with these legacy issues and into the green field of the cloud... The fact that we have these software technologies that now enable us to easily abstract from the chip hardware enables us to correct and improve the chips through community efforts as needs arise... We need to stop thinking about microprocessor systems' architectures as these licensed things that are developed in secrecy by mega-companies like Intel or AMD or even ARM... The reality is that we now need to create something new, free from any legacy entities and baggage that has been driving the industry and dragging it down the past 40 years. Just as was done with Linux. The bigger question is which chip should take its place. "I don't see ARM donating its IP to this effort, and I think OpenSPARC may not be it either. Perhaps IBM OpenPOWER? It would certainly be a nice gesture of Big Blue to open their specification up further without any additional licensing, and it would help to maintain and establish the company's relevancy in the cloud going forward. "RISC-V, which is being developed by UC Berkeley, is completely Open Source."' -- source: https://news.slashdot.org/story/18/01/06/0424200 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

After Intel ME, Researchers Find Security Bug In AMD's SPS Secret Chip-on-Chip
by Peter Reutemann 07 Jan '18

07 Jan '18

'AMD has fixed, but not yet released BIOS/UEFI/firmware updates for the general public for a security flaw affecting the AMD Secure Processor. This component, formerly known as AMD PSP (Platform Security Processor), is a chip-on-chip security system, similar to Intel's much-hated Management Engine (ME). Just like Intel ME, the AMD Secure Processor is an integrated coprocessor that sits next to the real AMD64 x86 CPU cores and runs a separate operating system tasked with handling various security-related operations. The security bug is a buffer overflow that allows code execution inside the AMD SPS TPM, the component that stores critical system data such as passwords, certificates, and encryption keys, in a secure environment and outside of the more easily accessible AMD cores. Intel fixed a similar flaw last year in the Intel ME.' -- source: https://hardware.slashdot.org/story/18/01/07/2015226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Munich Council: To Hell With Linux, We're Going Full Windows in 2020
by Peter Reutemann 04 Jan '18

04 Jan '18

'The German city of Munich, which received much popularity back in the day when it first ditched Microsoft's services in favor of open-source software, has now agreed to stop using Linux and switch back to Windows. If the decision is ratified by the full council in two weeks, Windows 10 will start rolling out across the city in 2020. From a report: A coalition of Social Democrats and Conservatives on the committee voted for the Windows migration last week, Social Democrat councillor Anne Hubner told The Register. Munich rose to fame in the open-source world for deciding to use Linux and LibreOffice to make the city independent from the claws of Microsoft. But the plan was never fully realised -- mail servers, for instance, eventually wound up migrating to Microsoft Exchange -- and in February the city council formally voted to end Linux migration and go back to Microsoft. Hubner said the city has struggled with LiMux adoption. "Users were unhappy and software essential for the public sector is mostly only available for Windows," she said. She estimated about half of the 800 or so total programs needed don't run on Linux and "many others need a lot of effort and workarounds." Hubner added, "in the past 15 years, much of our efforts were put into becoming independent from Microsoft," including spending "a lot of money looking for workarounds" but "those efforts eventually failed." A full council vote on Windows 10 2020 migration is set for November 23, Hubner said. However, the Social Democrats and Conservatives have a majority in the council, and the outcome is expected to be the same as in committee.' -- source: https://news.slashdot.org/story/17/11/13/1714220 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Roll On The Feudal Internet
by Lawrence D'Oliveiro 22 Dec '17

Quoted in <https://www.schneier.com/blog/archives/2017/12/amazons_door_lo.html>: The Key-compatible locks are made by Yale and Kwikset, yet don't work with those brands' own apps. They also can't connect with a home-security system or smart-home gadgets that work with Apple and Google software. And, of course, the lock can't be accessed by businesses other than Amazon. No Walmart, no UPS, no local dog-walking company. And so Amazon becomes a gatekeeper (literally) for access to your very home.

All 500 of the World's Top 500 Supercomputers Are Running Linux
by Peter Reutemann 19 Dec '17

19 Dec '17

'Linux rules supercomputing. This day has been coming since 1998, when Linux first appeared on the TOP500 Supercomputer list. Today, it finally happened: All 500 of the world's fastest supercomputers are running Linux. The last two non-Linux systems, a pair of Chinese IBM POWER computers running AIX, dropped off the November 2017 TOP500 Supercomputer list. When the first TOP500 supercomputer list was compiled in June 1993, Linux was barely more than a toy. It hadn't even adopted Tux as its mascot yet. It didn't take long for Linux to start its march on supercomputing. >From when it first appeared on the TOP500 in 1998, Linux was on its way to the top. Before Linux took the lead, Unix was supercomputing's top operating system. Since 2003, the TOP500 was on its way to Linux domination. By 2004, Linux had taken the lead for good. This happened for two reasons: First, since most of the world's top supercomputers are research machines built for specialized tasks, each machine is a standalone project with unique characteristics and optimization requirements. To save costs, no one wants to develop a custom operating system for each of these systems. With Linux, however, research teams can easily modify and optimize Linux's open-source code to their one-off designs. The semiannual TOP500 Supercomputer List was released yesterday. It also shows that China now claims 202 systems within the TOP500, while the United States claims 143 systems.' -- source: https://linux.slashdot.org/story/17/11/14/2223227 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Fear And Loathing In Open-Source Clothing Design
by Lawrence D'Oliveiro 18 Dec '17

18 Dec '17

Seems the Valentina project, to create an open-source clothing design package, has split in two over the usual reason--disagreements among the project members <http://libregraphicsworld.org/blog/entry/valentina-seamly2d>. In that article, Alexandre Prokoudine tries to give an even-handed account of the saga, which can sometimes be quite difficult. The proprietary software in this field is extremely expensive--to the point where it becomes hard for clothing makers/designers to hire people who are familiar with using it. An alternative project, called SodaCAD <http://www.sodacad.org/>, takes a very different view: more direct control over the design (as I understand it), rather than trying to automatically fit a predefined design to given measurements, as Valentina does. It hasn’t seen much activity in over three years, though.

Why Linux HDCP Isn't the End of the World
by Peter Reutemann 17 Dec '17

17 Dec '17

'"There is no reason for the open-source community to worry..." writes Daniel Stone, who heads the graphics team at open-source consultancy Collabora. mfilion quotes Collabora.com: Recently, Sean Paul from Google's ChromeOS team, submitted a patch series to enable HDCP support for the Intel display driver. HDCP is used to encrypt content over HDMI and DisplayPort links, which can only be decoded by trusted devices... However, if you already run your own code on a free device, HDCP is an irrelevance and does not reduce freedom in any way.... HDCP support is implemented almost entirely in the hardware. Rather than adding a mandatory encryption layer for content, the HDCP kernel support is dormant unless userspace explicitly requests an encrypted link. It then attempts to enable encryption in the hardware and informs userspace of the result. So there's the first out: if you don't want to use HDCP, then don't enable it! The kernel doesn't force anything on an unwilling userspace.... HDCP is only downstream facing: it allows your computer to trust that the device it has been plugged into is trusted by the HDCP certification authority, and nothing more. It does not reduce user freedom, or impose any additional limitations on device usage.' -- source: https://linux.slashdot.org/story/17/12/16/0320227 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Net Neutrality Repeal --- What It Means For NZ

In NZ if my provider gives me crap access to certain services, I have options, but in many places in the US they do not. Net Neutrality rules did not increase competition in USA, and I do not see how dropping regulations in US will affect NZ's access. Just like Internet censorship from the department of internal affairs is optional, so will any media business arrangement with our ISPs.

Should Google Be Paying News Sites For Linking To Them?
by Lawrence D'Oliveiro 16 Dec '17

16 Dec '17

News agencies in Europe, particularly, have been claiming for a long while that Google has been unfairly profiting from linking to their articles (and quoting snippets from them). So they want Governments to force Google to pay a “link tax” <https://www.techdirt.com/articles/20171214/16352638814/european-new-agencie…>. The reality of such things is that, regardless of laws to the contrary, the money tends to flow from the ones benefiting to the ones providing the value (cf the “Payola” scandals in the US). Which explains what happened in Spain after it brought in its link-tax law <https://www.techdirt.com/articles/20150725/14510131761/study-spains-google-…>. Maybe the news agencies’ real complaint is that Google is such a massively profitable advertising company.

by Rowan Schischka 16 Dec '17

16 Dec '17

>Doesn?t mean we shouldn?t have network neutrality here, though. It just >means the abuses have not been quite as flagrant to date. The article is about ghost problems. In America, with or without net neutrality, providers abuse their market position. Every argument to keep the net neutrality rules comes back to poor competition in telco providers, which previous regulations did not address. The article correctly states that we will not see problems here because of Chrous' position but they incorrectly state we do not have links between media and ISP; Vodafone currently offers package deals https:// www.vodafone.co.nz/pass/ The internet is still working and there is no barrier to stop you or me to start a competing business. If a company like Duco or the rugby union did a deal with an ISP, I would want a deal that gives me uninterrupted live sports streaming, but it wont happen if the government thinks they need to regulate this.

Avast Launches Open-Source Decompiler For Machine Code
by Peter Reutemann 14 Dec '17

14 Dec '17

'To help with the reverse engineering of malware, Avast has released an open-source version of its machine-code decompiler, RetDec, that has been under development for over seven years. RetDec supports a variety of architectures aside from those used on traditional desktops including ARM, PIC32, PowerPC and MIPS. As Internet of Things devices proliferate throughout our homes and inside private businesses, being able to effectively analyze the code running on all of these new devices becomes a necessity to ensure security. In addition to the open-source version found on GitHub, RetDec is also being provided as a web service. Simply upload a supported executable or machine code and get a reasonably rebuilt version of the source code. It is not possible to retrieve the exact original code of any executable compiled to machine code but obtaining a working or almost working copy of equivalent code can greatly expedite the reverse engineering of software. For any curious developers out there, a REST API is also provided to allow third-party applications to use the decompilation service. A plugin for IDA disassembler is also available for those experienced with decompiling software.' -- source: https://news.slashdot.org/story/17/12/14/006237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

They are not there to tell us to Go Away. They are there to keep the system running while we discover it, use it, develop it, innovate it, game it, finesse it, and reinvent it to our heart's content. The great enterprise of telecommunications is no better than our right to participate in it as individuals.

AMD Is Open-Sourcing Their Official Vulkan Linux Driver

The code drop is imminent and they are encouraging the use of it for quick support of new AMD hardware, access to the Radeon GPU Profiler, easy integration of AMD Vulkan extensions, and enabling third-party extensions.

1998 attack that messes with sites’ secret crypto keys is back in a big way
by Peter Reutemann 12 Dec '17

12 Dec '17

'A surprisingly big number of top-name websites—Facebook and PayPal among them—recently tested positive for a critical, 19-year-old vulnerability that allowed attackers to decrypt encrypted data and sign communications using the sites' secret encryption key. The vulnerability in the transport layer security protocol for Web encryption was disclosed in 1998 when researcher Daniel Bleichenbacher found it in the TLS predecessor known as secure sockets layer. A flaw in the algorithm that handles RSA encryption keys responded to certain types of errors in a way that divulged potentially sensitive information. With enough specially formed queries, attackers could exploit the weakness in a way that allowed them to decrypt ciphertext even when they didn't have the secret decryption key. SSL architects responded by designing workarounds that suppressed the error messages rather than removing or rewriting the faulty RSA algorithm. Researchers call the class of crypto vulnerability an Oracle because it provides only "yes" or "no" answers that, over time, can reveal detailed information about the contents of encrypted data. The information allows hackers to carry out what's known as an "adaptive chosen-ciphertext attack."' -- source: https://arstechnica.com/information-technology/2017/12/a-worrying-number-of… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Should Service Providers Be Liable For Content?
by Lawrence D'Oliveiro 11 Dec '17

It is commonly accepted that ISPs should not generally be held liable for things done by their customers--or indeed, anybody else’s customers over their pipes. This is currently the case in Australia, for example. But should protections be extended to what we might describe as “secondary” service providers--such as social media sites like Facebook, and of course Google? Seems like Australia agrees the answer should be mostly “yes”, but not for those specific companies. Not sure how they are going to decide who is eligible for such legal protections and who is not. <https://www.techdirt.com/articles/20171207/09383538762/mpaa-wins-australia-…>

Intel's ME May Be Massively Infringing on Minix3's Free Software License
by Peter Reutemann 10 Dec '17

10 Dec '17

'Almost all Free Software licenses (BSD, MIT, GPL...) require some sort of legal notice (legal attribution) given to the recipient of the software, both when the software is distributed in source and in binary forms. The legal notice usually contains the copyright holder's name and the license text. This means that it's not possible to hide and keep secret the existence of Free Software that you have stuck into your product that you distribute. If you do so, then you are not complying with the Free Software license and you are committing a copyright infringement! This is exactly what Intel seems to have done with the Intel ME. The Minix3 operating system license requires a legal notice, but so far it seems like Intel has not given the necessary legal notices. (Probably because they want to keep the inside of the ME secret.) Thus not only is Minix3 the most installed OS on our recent x86 CPUs -- but it might also the most pirated OS on our recent x86 CPUs!' -- source: https://slashdot.org/story/17/12/09/0610203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The FCC Still Doesn’t Know How the Internet
by Peter Reutemann 10 Dec '17

'The EFF describes the FCC's official plan to kill net neutrality as "riddled with technical errors and factual inaccuracies," including, for example, a false distinction between "Internet access service" and "a distinct transmission service" which the EFF calls "utterly ridiculous and completely ungrounded from reality." "Besides not understanding how Internet access works, the FCC also has a troublingly limited knowledge of how the Domain Name System (DNS) works -- even though hundreds of engineers tried to explain it to them this past summer... As the FCC would have it, an Internet user actively expects their ISP to provide DNS to them." And in addition, "Like DNS, it treats caching as if it were some specialized service rather than an implementation detail and general-purpose computing technique." "There are at least two possible explanations for all of these misunderstandings and technical errors. One is that, as we've suggested, the FCC doesn't understand how the Internet works. The second is that it doesn't care, because its real goal is simply to cobble together some technical justification for its plan to kill net neutrality. A linchpin of that plan is to reclassify broadband as an 'information service,' (rather than a 'telecommunications service,' or common carrier) and the FCC needs to offer some basis for it. So, we fear, it's making one up, and hoping no one will notice." "We noticed," their editorial ends, urging Americans "to tell your lawmakers: Don't let the FCC sell the Internet out."' -- source: https://yro.slashdot.org/story/17/12/09/0545230 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A bunch of Canadian ISPs, together with various entertainment groups, is submitting a plan to the Canadian Radio-television and Communications Commission (CRTC), which is the regulatory body for broadcasting and telecoms, to maintain a list of sites which will be blocked by the ISPs at the request of the entertainment groups. Is there any recourse, any review process, any independent oversight? Nope. Any prospect for, shall we say, “mission creep”? Oh boy, is there... The CRTC seems less than enthused. I like this comment from their spokesperson: “Our government supports an open internet where Canadians have the ability to access the content of their choice in accordance to Canadian laws,” Sasseville says. “While other parts of the world are focused on building walls, we’re focused on opening doors‎.”

There is a tussle going on at the moment between a couple of large corporations--but then, isn’t there always? There is a saying in some parts of Africa that “when elephants fight, the grass gets trampled”. The “grass”, in this case, being ordinary consumers like you and me. * Once Amazon started offering its own video-streaming hardware, it banned competing products offered by Apple and Google from its store. (Can you say “conflict of interest”?) * Google/YouTube retaliated by blocking YouTube from Amazon’s Echo Show. * Amazon upped the ante by denying sales of Google’s Nest devices as well. And so it goes... <https://www.techdirt.com/articles/20171206/10385638755/google-amazon-are-ha…>

Windows RT Strike 2
by Lawrence D'Oliveiro 06 Dec '17

06 Dec '17

The first Windows-10-on-ARM machines are due to ship from HP and Asus in the autumn <https://arstechnica.com/gadgets/2017/12/hp-asus-announce-first-windows-10-a…>. It will include some kind of x86 emulator to run 32-bit regular-Windows apps. Of which I didn’t realize that there were still many around. Of course you can have either the ARM native performance and the long battery life, or you can have the Windows compatibility, but you are not going to get both at once. Prognosis: whenever either member of the Wintel symbiote has tried to step out on their own, the results have been uniformly disastrous. I expect this foray to be no different.

MacOS High Sierra Bug Allows Login As Root With No Password
by Peter Reutemann 04 Dec '17

04 Dec '17

'A trivial-to-exploit flaw in macOS High Sierra, aka macOS 10.13, allows users to gain admin rights, or log in as root, without a password. The security bug is triggered via the authentication dialog box in Apple's operating system, which prompts you for an administrator's username and password when you need to do stuff like configure privacy and network settings. If you type in "root" as the username, leave the password box blank, hit "enter" and then click on unlock a few times, the prompt disappears and, congrats, you now have admin rights. You can do this from the user login screen. The vulnerability effectively allows someone with physical access to the machine to log in, cause extra mischief, install malware, and so on. You should not leave your vulnerable Mac unattended until you can fix the problem. And while obviously this situation is not the end of the world -- it's certainly far from a remote hole or a disk decryption technique -- it's just really, really sad to see megabucks Apple drop the ball like this. Developer Lemi Orhan Ergan was the first to alert the world to the flaw. The Register notes: "If you have a root account enabled and a password for it set, the black password trick will not work. So, keep the account enabled and set a root password right now..."' -- source: https://it.slashdot.org/story/17/11/28/2135236 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Researchers Run Unsigned Code on Intel ME By Exploiting USB Ports
by Peter Reutemann 04 Dec '17

04 Dec '17

'A pair of security researchers in Russia are claiming to have compromised the Intel Management Engine just using one of the computer's USB ports. The researchers gained access to a fully functional JTAG connection to Intel CSME via USB DCI. The claim is different from previous USB DCI JTAG examples from earlier this year. Full JTAG access to the ME would allow making permanent hidden changes to the machine. "Getting into and hijacking the Management Engine means you can take full control of a box," reports the Register, "underneath and out of sight of whatever OS, hypervisor or antivirus is installed." They add that "This powerful God-mode technology is barely documented," while The Next Web points out that USB ports are "a common attack vector."' -- source: https://it.slashdot.org/story/17/11/11/237236 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Is Open Source Innovation Now All About Vendor On-Ramps?
by Peter Reutemann 03 Dec '17

03 Dec '17

'InfoWorld published an interesting essay from Matt Asay, former COO at Canonical (and an emeritus board member of the Open Source Initiative), about innovation from the big public cloud vendors, which "even when open-sourced, doesn't really help the community at large... All this innovation is available to buy; none of it is available to build. Not for mere mortals, anyway." Google in particular has figured out how to both open-source code in a useful way and make it pay. As Server Density CEO David Mytton has underlined, Google hopes to "standardize machine learning on a single framework and API," namely TensorFlow, then supplement it "with a service that can [manage] it all for you more efficiently and with less operational overhead," namely Google Cloud. By open-sourcing TensorFlow and backing it with machine-learning-heavy Google Cloud, Google has open-sourced a great on-ramp to future revenue. My question: why not do this with the rest of its code? The simple answer is "Because it's a lot of work." That is, Google could open-source everything tomorrow without any damage to its revenue, but the code itself would provide other providers and enterprises only limited ability to increase their revenue unless Google did all the necessary prep work to make it useful to mere mortals not running superhuman Google infrastructure. This is the trick that AWS, Microsoft, and Google are all racing to figure out today. Not open source, per se, because that's the easy table stakes. No, the AWS/Microsoft Azure/Google Cloud trio are figuring out how to turn their innovations into open source on-ramps to their proprietary services. Companies used to lock up their code to sell it. Today, it's the opposite: They need to open it up to make their ability to operate the code at scale more valuable. For them.' -- source: https://news.slashdot.org/story/17/12/02/0833217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Understanding the New Red Hat-IBM-Google-Facebook GPL Enforcement Announcement
by Peter Reutemann 03 Dec '17

03 Dec '17

'Bruce Perens co-founded the Open Source Initiative with Eric Raymond -- and he's also Slashdot reader #3872. Bruce Perens writes: Red Hat, IBM, Google, and Facebook announced that they would give infringers of their GPL software up to a 30-day hold-off period during which an accused infringer could cure a GPL violation after one was brought to their attention by the copyright holder, and a 60 day "statute of limitations" on an already-cured infringement when the copyright holder has never notified the infringer of the violation. In both cases, there would be no penalty: no damages, no fees, probably no lawsuit; for the infringer who promptly cures their infringement. Perens sees the move as "obviously inspired" by the kernel team's earlier announcement, and believes it's directed against one man who made 50 copyright infringement claims involving the Linux kernel "with intent to collect income rather than simply obtain compliance with the GPL license." Unfortunately, "as far as I can tell, it's Patrick McHardy's legal right to bring such claims regarding the copyrights which he owns, even if it doesn't fit Community Principles which nobody is actually compelled to follow."' -- source: https://linux.slashdot.org/story/17/12/02/2024240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'24 Pull Requests' Suggests Contributing Code For Christmas
by Peter Reutemann 03 Dec '17

03 Dec '17

'"On December 1st, 24 Pull Requests will be opening its virtual doors once again, asking you to give the gift of a pull request to an open source project in need," writes UK-based software developer Andrew Nesbitt -- noting that last year the site registered more than 16,000 pull requests. "And they're not all by programmers. Often the contribution with the most impact might be an improvement to technical documentation, some tests, or even better -- guidance for other contributors." This year they're even touting "24 Pull Requests hack events," happening around the world from Lexington, Kentucky to Torino, Italy. (Last year 80 people showed up for an event in London.) "You don't have to hack alone this Christmas!" suggests the site, also inviting local communities and geek meetups (as well as open source-loving companies) to host their own events. Contributing to open source projects can also beef up your CV (for when you're applying for your next job), the site points out, and "Even small contributions can be really valuable to a project." "You've been benefiting from the use of open source projects all year. Now is the time to say thanks to the maintainers of those projects, and a little birdy tells me that they love receiving pull requests!"' -- source: https://developers.slashdot.org/story/17/12/03/2018213 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Net Un-Neutrality ... For Real
by Lawrence D'Oliveiro 01 Dec '17

01 Dec '17

Some of those who have been following the net neutrality debate may remember a spoof poster that showed what might happen if ISPs were allowed to charge you differently, based on which sites you were allowed to visit. Well, in Spain, which has no laws against this sort of thing, a similar situation has actually happened: one ISP is selling you addons to a basic broadband cap based, not on the amount of extra data you want, but on what you want to use it for. Their “Vodafone Pass” product offers tiers like €3/month extra for a “Social Pass”, or €5/month for a “Music Pass”. <https://pplware.sapo.pt/informacao/vodafone-portugal-pacotes-smartnet/>, referenced from <https://www.techdirt.com/articles/20171030/12364538513/portugal-shows-inter…>

30 Years Of HyperCard

Just came across this item <https://blog.archive.org/2017/08/11/hypercard-on-the-archive-celebrating-30…> at archive.org about an online emulator that runs HyperCard stacks. HyperCard, in case you didn’t know, was an application created by Apple Macintosh engineer Bill Atkinson for that platform in 1987, and it was always hard to describe exactly what it was for. But it allowed users to create their own applications, aka “stacks”, around a card-based paradigm. One of the commenters points out that the basic idea is still alive and well, in the form of LiveCode, which is available as a paid online service <https://livecode.com/> and also in the form of Free Software <https://github.com/livecode/>.

Internet-paralyzing Mirai botnet comes roaring back with new strain
by Peter Reutemann 29 Nov '17

29 Nov '17

'Mirai, the Internet-of-things malware that turns cameras, routers, and other household devices into potent distributed denial-of-service platforms, may be lying low, but it's certainly not dead. Last week, researchers identified a new outbreak that infected almost 100,000 devices in a matter of days. In September of last year, Mirai emerged as a force to be reckoned with when it played a key role in silencing one of the most intrepid sources of security news in then-record-setting DDoS attacks topping 620 gigabits per second. Within a few weeks, Mirai's developer published the source code, a feat that allowed relatively unsophisticated people to wage the same types of extraordinarily big assaults. The release almost immediately helped touch off a series of large-scale attacks. The most serious one degraded or completely took down Twitter, GitHub, the PlayStation network, and hundreds of other sites by targeting Dyn, a service that provided domain name services to the affected sites. Last week, researchers from China-based Netlab 360 say they spotted a new, publicly available Mirai variant. The changes allowed the malware to spread to networking devices made by ZyXEL Communications that could be remotely accessed over telnet using default passwords. One of the exploits was published on October 31. Over a span of 60 hours starting on November 22, the new Mirai strain was able to commandeer almost 100,000 devices. Virtually all of the infected devices used IP addresses local to Argentina, a possible indication the outbreak targeted customers of a regional service provider who were assigned unsecured modems.' -- source: https://arstechnica.com/information-technology/2017/11/internet-paralyzing-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

66 Percent of Popular Android Cryptocurrency Apps Don't Use Encryption

'High-Tech Bridge used its free mobile app analysis software, called Mobile X-Ray, to peek under the hood of the top 30 cryptocurrency apps in the Google Play store at three different popularity levels: apps with up to 100,000 downloads, up to 500,000 downloads, and apps with more than 500,000 downloads. So, a total of 90 apps altogether. Of the most popular apps, 94 percent used outdated encryption, 66 percent didn't use HTTPS to encrypt user information in transit, 44 percent used hard-coded default passwords (stored in plain text in the code), and overall 94 percent of the most popular apps were found to have "at least three medium-risk vulnerabilities."' -- source: https://it.slashdot.org/story/17/11/29/1610245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Bigger Drives, Bigger Buffers
by Lawrence D'Oliveiro 29 Nov '17

29 Nov '17

What caught my eye about this <http://www.theregister.co.uk/2017/11/28/toshiba_10tb_surveillance_drive/> was But the new drives have a doubled buffer, at 256MiB, ... Why should hard drives have large “buffers” in them at all? Their job is to read and write the data specified to them by the OS driver, no more and no less. Bigger buffers increase latency, and 256MiB seems absolutely massive and unnecessary. And then there’s the issue where the drive tells the OS that the data has been written, but in fact it is still sitting in a memory buffer. So it could still be lost if a power outage happens in the next few milliseconds. Telling lies like this seems to be all about looking good in benchmarks, and to hell with safeguarding data integrity.

Ubuntu 17.10: Return of the GNOME
by Peter Reutemann 27 Nov '17

27 Nov '17

'If you've been following the Linux world at all, you know this has been an entire year for spring cleaning. Early in 2017, Canonical stopped work on its homegrown Unity desktop, Mir display server, and its larger vision of "convergence"—a unified interface for Ubuntu for phones, tablets, and desktops. And now almost exactly six years after Ubuntu first switched from GNOME 2 to the Unity desktop, that has been dropped, too. The distro is back to GNOME, and Canonical recently released Ubuntu 17.10, a major update with some significant changes coming to the popular Ubuntu Linux operating system. In light of the GNOME switch, this release seems like more of a homecoming than an entirely new voyage. But that said, Ubuntu 17.10 simultaneously feels very much like the start of a new voyage for Ubuntu. The last few Ubuntu desktop releases have been about as exciting as OpenSSH releases—you know you need to update, but beyond that, no one really cares. Sure, there have been a few feature updates with each new numeric increment, perhaps some slightly more up-to-date GNOME and GTK components under the hood. But by and large, Ubuntu's Unity 7 desktop has been in maintenance mode for several years. That period of stagnation turned Ubuntu from one of the more interesting operating systems around into just another Linux distro barely worthy of mention. This trend changes with 17.10. There are big changes—an entirely new default desktop in fact—but this release feels different not because the desktop has changed, but because Ubuntu feels like it once again has a sense of focus and direction. Even Canonical's letter-based naming scheme has arrived at a starting over point: "Artful Aardvark" is 17.10's nickname.' -- source: https://arstechnica.com/gadgets/2017/11/ubuntu-17-10-return-of-the-gnome/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Clear Linux Beats CentOS, openSUSE, and Ubuntu in (Enterprise) Benchmark Tests
by Peter Reutemann 27 Nov '17

27 Nov '17

'Recently completed Linux distro benchmarks by Phoronix show Intel's Clear Linux is the most powerful on x86 hardware. A six-way, enterprise-focused Linux distro comparison show Clear Linux being the fastest with a Core i9 and Xeon systems, easily beating CentOS, openSUSE, and Ubuntu in a majority of the tests. When doing an 11-way Linux distro boot test they also found Clear Linux easily booted the fastest followed by the Clear-inspired Solus distribution. Clear Linux does work on AMD hardware and works on Intel CPUs back to Sandy Bridge but leverages its speed from optimized compiler settings, specially built libraries capable of AVX instructions on supported systems, a specially tuned kernel configuration, and other optimizations/patches. Debian 9.2 and Fedora 27 "ended up being dropped from this article due to data overload," the article concludes, "and those distributions really not offering anything really different in terms of the performance."' -- source: https://linux.slashdot.org/story/17/11/27/0227218 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

There's A Cluster of 750 Raspberry Pi's at Los Alamos National Lab
by Peter Reutemann 26 Nov '17

26 Nov '17

'Slashdot reader overheardinpdx shares a video from the SC17 supercomputing conference where Bruce Tulloch from BitScope "describes a low-cost Rasberry Pi cluster that Los Alamos National Lab is using to simulate large-scale supercomputers." Slashdot reader mspohr describes them as "five rack-mount Bitscope Cluster Modules, each with 150 Raspberry Pi boards with integrated network switches." With each of the 750 chips packing four cores, it offers a 3,000-core highly parallelizable platform that emulates an ARM-based supercomputer, allowing researchers to test development code without requiring a power-hungry machine at significant cost to the taxpayer. The full 750-node cluster, running 2-3 W per processor, runs at 1000W idle, 3000W at typical and 4000W at peak (with the switches) and is substantially cheaper, if also computationally a lot slower. After development using the Pi clusters, frameworks can then be ported to the larger scale supercomputers available at Los Alamos National Lab, such as Trinity and Crossroads. BitScope's Tulloch points out the cluster is fully integrated with the network switching infrastructure at Los Alamos National Lab, and applauds the Raspberry Bi cluster as "affordable, scalable, highly parallel testbed for high-performance-computing system-software developers."' -- source: https://hardware.slashdot.org/story/17/11/25/051211 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How Four Microsoft Engineers Proved That The “Darknet” Would Defeat DRM
by Lawrence D'Oliveiro 24 Nov '17

24 Nov '17

A rerun of an article published five years ago, about a (in)famous paper from 2002 <https://arstechnica.com/tech-policy/2017/11/how-four-microsoft-engineers-pr…>: By itself, the paper's clever and provocative argument likely would have earned it a broad readership. But the really remarkable thing about the paper is who wrote it: four engineers at Microsoft whose work many expected to be at the foundation of Microsoft's future DRM schemes. The paper's lead author told Ars that the paper's pessimistic view of Hollywood's beloved copy protection schemes almost got him fired. But ten years later [2012], its predictions have proved impressively accurate. ... While Biddle and his colleagues didn't succeed in allaying the fears of Palladium's critics, the paper's central arguments have held up well. The authors predicted that the emergence of the darknet would produce a technological and legal arms race. They thought content companies and law enforcement would attack those aspects of the darknet that were most centralized, but that the darknet would adapt through greater decentralization. And they predicted that efforts to build secure DRM schemes would continue to fail. All of their predictions have continued to hold true over the last decade. And still continue to hold true.

How a Wi-Fi Pineapple Can Steal Your Data (And How To Protect Yourself From It)
by Peter Reutemann 23 Nov '17

23 Nov '17

'The Wi-Fi Pineapple is a cheap modified wireless router enables anyone to execute sophisticated exploits on Wi-Fi networks with little to no networking expertise. A report in Motherboard explains how it can be used to run a Wall of Sheep and execute a man-in-the-middle attack, as well as how you can protect yourself from Pineapple exploits when you're connected to public Wi-Fi. "... it's important that whenever you are done connecting to a public Wi-Fi network that you configure your phone or computer to 'forget' that network. This way your device won't be constantly broadcasting the SSIDs of networks it has connected to in the past, which can be spoofed by an attacker with a Pineapple," reports Motherboard. "Unfortunately there is no easy way to do this on an Android or an iPhone, and each network must be forgotten manually in the 'Manage Network' tab of the phone's settings. Another simple solution is to turn off your Wi-Fi functionality when you're not using it -- though that isn't as easy to do on some devices anymore -- and don't allow your device to connect to automatically connect to open Wi-Fi net' -- source: https://yro.slashdot.org/story/17/11/21/2255254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hiring an eSports champion to do simulation testing, even before you build a real racecar: ... make no mistake, simulator driver is a proper job in the modern F1 team.

PC vendors scramble as Intel announces vulnerability in firmware
by Peter Reutemann 22 Nov '17

22 Nov '17

'Intel has issued a security alert that management firmware on a number of recent PC, server, and Internet-of-Things processor platforms is vulnerable to remote attack. Using the vulnerabilities, the most severe of which was uncovered by Mark Ermolov and Maxim Goryachy of Positive Technologies Research, remote attackers could launch commands on a host of Intel-based computers, including laptops and desktops shipped with Intel Core processors since 2015. They could gain access to privileged system information, and millions of computers could essentially be taken over as a result of the bug.' -- source: https://arstechnica.com/information-technology/2017/11/intel-warns-of-wides… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google collects Android users’ locations even when location services are disabled
by Peter Reutemann 21 Nov '17

21 Nov '17

'Many people realize that smartphones track their locations. But what if you actively turn off location services, haven’t used any apps, and haven’t even inserted a carrier SIM card? Even if you take all of those precautions, phones running Android software gather data about your location and send it back to Google when they’re connected to the internet, a Quartz investigation has revealed. Since the beginning of 2017, Android phones have been collecting the addresses of nearby cellular towers—even when location services are disabled—and sending that data back to Google. The result is that Google, the unit of Alphabet behind Android, has access to data about individuals’ locations and their movements that go far beyond a reasonable consumer expectation of privacy.' -- source: https://qz.com/1131515/google-collects-android-users-locations-even-when-lo… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

No, you’re not being paranoid. Sites really are watching your every move
by Peter Reutemann 20 Nov '17

20 Nov '17

'If you have the uncomfortable sense someone is looking over your shoulder as you surf the Web, you're not being paranoid. A new study finds hundreds of sites—including microsoft.com, adobe.com, and godaddy.com—employ scripts that record visitors' keystrokes, mouse movements, and scrolling behavior in real time, even before the input is submitted or is later deleted. Session replay scripts are provided by third-party analytics services that are designed to help site operators better understand how visitors interact with their Web properties and identify specific pages that are confusing or broken. As their name implies, the scripts allow the operators to re-enact individual browsing sessions. Each click, input, and scroll can be recorded and later played back. A study published last week reported that 482 of the 50,000 most trafficked websites employ such scripts, usually with no clear disclosure. It's not always easy to detect sites that employ such scripts. The actual number is almost certainly much higher, particularly among sites outside the top 50,000 that were studied.' -- source: https://arstechnica.com/tech-policy/2017/11/an-alarming-number-of-sites-emp… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Technology groups and dealing with predators
by Bryce Utting 20 Nov '17

20 Nov '17

The Verge has a detailed (read: graphic) report of predatory behaviour from ex-Auckland security expert Morgan Marquis-Boire, late of Google and the Citizen Lab of the University of Toronto, with connections to the Freedom of the Press Foundation, the EFF, and presumably others. Content warning for sexual assault issues: https://www.theverge.com/2017/11/19/16675704/morgan-marquis-boire-hacker-se… I can only commend those who have come forward, and also Ron Deibert of Citizen Lab for his well-aimed response. Without opening old wounds, I'd suggest that the Citizen Lab code of conduct might be useful food for thought where public WLUG events are involved. (unless a code of conduct already exists and I missed it?) A separate incorporated society I'm involved in has had to deal with complaints of a predator at an event, and a similar document could have done wonders for laying out how to appropriately evaluate and respond in the absence of a police complaint.The Harvey Weinstein disclosures are making clear how endemic this behaviour is, and how rare appropriate responses are. butting

Intel Planning To End Legacy BIOS Support By 2020, Report Says
by Peter Reutemann 20 Nov '17

20 Nov '17

'Intel is planning to end "legacy BIOS" support in their new platforms by 2020 in requiring UEFI Class 3 or higher. Making rounds this weekend is a slide deck from the recent UEFI Plugfest. Brian Richardson of Intel talked about the "last mile" barriers to removing legacy BIOS support from systems. By 2020, they will be supporting no less than UEFI Class 3, which means only UEFI support and no more legacy BIOS or CSM compatibility support mode. But that's not going to force on UEFI Secure Boot unconditionally: Secure Boot enabled is considered UEFI Class 3+. Intel hasn't removed legacy BIOS / CSM support yet due to many customers' software packages still relying upon legacy BIOS, among other reasons. Removing the legacy BIOS support will mitigate some security risks, needs less validation by vendors, allows for supporting more modern technologies, etc.' -- source: https://tech.slashdot.org/story/17/11/20/1251249 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Another Tor Browser Feature Makes It Into Firefox: First-Party Isolation
by Peter Reutemann 20 Nov '17

20 Nov '17

'Unbeknown to most users, Mozilla added a privacy-enhancing feature to the Firefox browser over the summer that can help users block online advertisers from tracking them across the Internet. The feature is named First-Party Isolation (FPI) and was silently added to the Firefox browser in August, with the release of Firefox 55. FPI works by separating cookies on a per-domain basis. This is important because most online advertisers drop a cookie on the user's computer for each site the user visits and the advertisers loads an ad. With FPI enabled, the ad tracker won't be able to see all the cookies it dropped on that user's PC, but only the cookie created for the domain the user is currently viewing. This will force the ad tracker to create a new user profile for each site the user visits and the advertiser won't be able to aggregate these cookies and the user's browsing history into one big fat profile. This feature was first implemented in the Tor Browser, a privacy-focused fork of the Firefox browser managed by the Tor Project, where it is known as Cross-Origin Identifier Unlinkability. FPI was added to Firefox as part of the Tor Uplift project, an initiative to bolster the Firefox codebase with some of the Tor Browser's unique privacy-focused features. The feature is not enabled by default. Information on how to enable it is in the linked article.' -- source: https://news.slashdot.org/story/17/11/20/1713235 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Bluetooth Hack Affects 20 Million Amazon Echo, Google Home Devices
by Peter Reutemann 17 Nov '17

17 Nov '17

'In September, security researchers discovered eight vulnerabilities -- codenamed collectively as BlueBorne -- in the Bluetooth implementations used by over 5.3 billion devices. We have now learned that an estimated 20 million Amazon Echo and Google Home devices are also vulnerable to attacks leveraging the BlueBorne vulnerabilities. The Hacker News reports: Amazon Echo is affected by the following two vulnerabilities: a remote code execution vulnerability in the Linux kernel (CVE-2017-1000251); and an information disclosure flaw in the SDP server (CVE-2017-1000250). Since different Echo's variants use different operating systems, other Echo devices are affected by either the vulnerabilities found in Linux or Android. Whereas, Google Home devices are affected by one vulnerability: information disclosure vulnerability in Android's Bluetooth stack (CVE-2017-0785). This Android flaw can also be exploited to cause a denial-of-service (DoS) condition. Since Bluetooth cannot be disabled on either of the voice-activated personal assistants, attackers within the range of the affected device can easily launch an attack. The security firm [Armis, who disclosed the issue] notified both Amazon and Google about its findings, and both companies have released patches and issued automatic updates for the Amazon Echo and Google Home that fixes the BlueBorne attacks.

A History Of The Amiga, Part 11
by Lawrence D'Oliveiro 14 Nov '17

14 Nov '17

<https://arstechnica.com/gaming/2017/11/a-history-of-the-amiga-part-11-betwe…>: Then came an announcement that caused an uproar in the Amiga community; some even saw it as a betrayal. Jim Collas’ team revealed that it was switching the OS kernel for Amiga OE from QNX to Linux. ... In retrospect, this was probably the correct choice. Linux, then and now, supported a much more diverse array of hardware and was already gaining significant momentum in the tech industry. But Amiga fans didn’t see it that way at the time. They saw Linux as bloated, clunky, and slow, the exact opposite of their beloved Amiga. QNX Neutrino was seen as fast, small, and elegant, and the community had rallied behind it. This takes place in 1999. I did spend some time with Amiga fans about a decade earlier. Being a Mac fan at the time, I saw it as a bad move to tie to OS architecture so closely to particular quirks of the hardware. And sure enough, that did cause compatibility problems for Amiga software on later hardware.

New To Me: Game Asset Rippers
by Lawrence D'Oliveiro 12 Nov '17

12 Nov '17

While browsing around DeviantArt (as you do), I discovered this group <https://xnalaramodelandtuts.deviantart.com/>. The name “XNALara” comes from an open-source Windows program that let you create your own scenes and poses with assets (characters, props, scenery) from the “Tomb Raider: Underworld” game. (I think it has broadened its reach beyond that one game by now.) All very well, but how do you extract those assets from these games? Turns out there are these tools called “rippers”, which capture the OpenGL/DirectX drawing calls that the game makes and save all the geometry and textures and so on that are passed to those calls. (Did somebody say “copyright violation”?) Well, there are folders in that group that are absolutely full of these extracted assets. Some have been taken down on demand from the copyright owners, but the remarkable thing is that most of them are still available, and have been so for some years. And that the accounts of those uploading these collections have not been suspended. I tried loading one or two of them into Blender. There’s a range of formats, but one common combination is .obj+.mtl for the geometry and material definitions, and .dds for the texture images. The latter can be converted to PNG with ImageMagick and, after making corresponding edits to the references in the .mtl file, I was able to import the results and see something resembling the preview images. There have been artists on DeviantArt who have used these in their renders (and mentioned as much--that’s how I found out about them). I may try messing around with them a bit more, but I don’t think I’ll be publishing any such work...

3D Metal Printing At 100 Times The Speed And A Twentieth Of The Cost
by Lawrence D'Oliveiro 10 Nov '17

10 Nov '17

3D printing has mainly been confined to parts made out of various kinds of plastics up till now. Metal has been hard to deal with, because at some point you have to melt it, and that requires temperatures higher than any printing-type device could cope with. Now a company called “Desktop Metal” <http://www.theregister.co.uk/2017/11/10/metal_3d_printing_at_desktop_metal/> has come up with a scheme involving binding layers of metal powder, laid down in the right shape, using a temporary compound which is then removed when the part is melted in a furnace so it becomes a proper solid piece. Obviously this has to be done without losing its shape. The process can also do clever things like make a hinge, where there is no metal between the parts, so once the binding compound is removed, you have two solid parts that can freely rotate without falling apart.

From <https://arstechnica.com/information-technology/2017/11/how-av-can-open-you-…>: Antivirus programs, in many cases, make us safer on the Internet. Other times, they open us to attacks that otherwise wouldn't be possible. On Friday, a researcher documented an example of the latter—a vulnerability he found in about a dozen name-brand AV programs that allows attackers who already have a toehold on a targeted computer to gain complete system control.

MINIX: Intel's Hidden In-chip Operating System
by Peter Reutemann 09 Nov '17

09 Nov '17

'Matthew Garrett, the well-known Linux and security developer who works for Google, explained recently that, "Intel chipsets for some years have included a Management Engine [ME], a small microprocessor that runs independently of the main CPU and operating system. Various pieces of software run on the ME, ranging from code to handle media DRM to an implementation of a TPM. AMT [Active Management Technology] is another piece of software running on the ME." [...] At a presentation at Embedded Linux Conference Europe, Ronald Minnich, a Google software engineer reported that systems using Intel chips that have AMT, are running MINIX. So, what's it doing in Intel chips? A lot. These processors are running a closed-source variation of the open-source MINIX 3. We don't know exactly what version or how it's been modified since we don't have the source code. In addition, thanks to Minnich and his fellow researchers' work, MINIX is running on three separate x86 cores on modern chips. There, it's running: TCP/IP networking stacks (4 and 6), file systems, drivers (disk, net, USB, mouse), web servers. MINIX also has access to your passwords. It can also reimage your computer's firmware even if it's powered off. Let me repeat that. If your computer is "off" but still plugged in, MINIX can still potentially change your computer's fundamental settings. And, for even more fun, it "can implement self-modifying code that can persist across power cycles." So, if an exploit happens here, even if you unplug your server in one last desperate attempt to save it, the attack will still be there waiting for you when you plug it back in. How? MINIX can do all this because it runs at a fundamentally lower level. [...] According to Minnich, "there are big giant holes that people can drive exploits through." He continued, "Are you scared yet? If you're not scared yet, maybe I didn't explain it very well, because I sure am scared." Also read: Andrew S. Tanenbaum's (a professor of Computer Science at Vrije Universiteit) open letter to Intel' -- source: https://tech.slashdot.org/story/17/11/07/1041236 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Bruce Schneier On The Equifax Breach
by Lawrence D'Oliveiro 08 Nov '17

08 Nov '17

Security expert Bruce Schneier has published <https://www.schneier.com/blog/archives/2017/11/me_on_the_equif.html> the testimony he gave to the US House Energy and Commerce Committee on the breach of confidential personal information on close to half the entire population of the US. His main points are worth summarizing: 1. The Equifax breach was a serious security breach that puts millions of Americans at risk. 2. Equifax was solely at fault. 3. There are thousands of data brokers with similarly intimate information, similarly at risk. 4. These data brokers deliberately hide their actions, and make it difficult for consumers to learn about or control their data. 5. The existing regulatory structure is inadequate. 6. The market cannot fix this because we are not the customers of data brokers. 7. We need effective regulation of data brokers. 8. Resist complaints from the industry that this is "too hard." 9. This has foreign trade implications. 10. This has national security implications. 11. We need to do something about it. Read the article for more detail. I would say this is more than a US-specific problem, it is a worldwide problem. Other places may have stricter privacy regulations, but that might not be enough.

Linux Has a USB Driver Security Problem
by Peter Reutemann 08 Nov '17

08 Nov '17

'USB drivers included in the Linux kernel are rife with security flaws that in some cases can be exploited to run untrusted code and take over users' computers. The vast majority of these vulnerabilities came to light on Monday, when Google security expert Andrey Konovalov informed the Linux community of 14 vulnerabilities he found in the Linux kernel USB subsystem. "All of them can be triggered with a crafted malicious USB device in case an attacker has physical access to the machine," Konovalov said. The 14 flaws are actually part of a larger list of 79 flaws Konovalov found in Linux kernel USB drivers during the past months. Not all of these 79 vulnerabilities have been reported, let alone patched. Most are simple DoS (Denial of Service) bugs that freeze or restart the OS, but some allow attackers to elevate privileges and execute malicious code.' -- source: https://linux.slashdot.org/story/17/11/08/1730210 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Create & manage docker hosts with Docker Machine on VirtualBox
by Peter Reutemann 08 Nov '17

08 Nov '17

'Docker Machine is a tool that let us install Docker Engine on virtual hosts on various platforms, on local environment as well on cloud. With Docker Machine, we can easily install docker hosts a Windows machine, a MAC machine or on cloud platform like AWS, AZURE etc. As we know that Docker Engine runs natively on Linux machines, so its pretty easy to get Docker working on Linux machines but for other OS like MAC or Windows this was a problem. So Docker Machine was introduced, especially for older versions of MAC & Windows (there are new native Docker apps for latest OS). Not meant only for Windows or MAC, Docker machine also provides efficient way to provision multiple Docker hosts on local as well as cloud network. To manage the docker hosts, we use rather than using ‘docker’ command, which is used with docker engine.

"Our research shows that a 'basic,' functional office suite, which is streamlined with a 'simple' and uncluttered, uncomplicated UI, serves an incredible under-represented community. "Other office suites are focusing on the 'power user' which is a valuable market, for sure, but the real power and range for an open-source office suite alternative is the vast majority which is the 'rest of us.

No, the Linux Desktop Hasn't Jumped in Popularity
by Peter Reutemann 06 Nov '17

06 Nov '17

'Stories have been circulating that the Linux desktop had jumped in popularity and was used more than macOS. Alas, it's not so... These reports have been based on NetMarketShare's desktop operating system analysis, which showed Linux leaping from 2.5 percent in July, to almost 5 percent in September. But unfortunately for Linux fans, it's not true... It seems to be merely a mistake. Vince Vizzaccaro, NetMarketShare's executive marketing share of marketing told me, "The Linux share being reported is not correct. We are aware of the issue and are currently looking into it"... For the most accurate, albeit US-centric operating system and browser numbers, I prefer to use data from the federal government's Digital Analytics Program (DAP). Unlike the others, DAP's numbers come from billions of visits over the past 90 days to over 400 US executive branch government domains... DAP gets its raw data from a Google Analytics account. DAP has open-sourced the code, which displays the data on the web and its data-collection code... In the US Analytics site, which summarizes DAP's data, you will find desktop Linux, as usual, hanging out in "other" at 1.5 percent. Windows, as always, is on top with 45.9 percent, followed by Apple iOS, at 25.5 percent, Android at 18.6 percent, and macOS at 8.5 percent. The article does, however, acknowledge that Linux's real market share is probably a little higher simply because "no one, not even DAP, seems to do a good job of pulling out the Linux-based Chrome OS data' -- source: https://linux.slashdot.org/story/17/11/05/202232 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

A Walkthrough Of The Windows Subsystem For Linux
by Lawrence D'Oliveiro 05 Nov '17

Here <https://www.youtube.com/watch?v=VSqAyOY5huQ> is a nice intro to the Linux compatibility layer that Microsoft has added to Windows 10. Their app store gives you a choice of Ubuntu or two flavours of SuSE. But while these omit any X server functionality, they do include all the GUI X clients. So it is perfectly possible to install a Windows-native X server, such as the open-source VcXsrv <https://sourceforge.net/projects/vcxsrv/>. And then he uses this to demonstrate running a full XFCE desktop side-by-side with the regular Windows desktop.

Mozilla Might Distrust Dutch Government Certs Over 'False Keys'
by Peter Reutemann 05 Nov '17

05 Nov '17

'Mozilla engineers are discussing plans to remove support for a state-operated Dutch TLS/HTTPS provider after the Dutch government has voted a new law that grants local authorities the power to intercept Internet communications using "false keys". If the plan is approved, Firefox will not trust certificates issued by the Staat der Nederlanden (State of the Netherlands) Certificate Authority (CA)... This new law gives Dutch authorities the powers to intercept and analyze Internet traffic. While other countries have similar laws, what makes this one special is that authorities will have authorization to carry out covert technical attacks to access encrypted traffic. Such covert technical capabilities include the use of "false keys," as mentioned in Article 45 1.b, a broad term that includes TLS certificates. "Fears arise of mass Dutch Internet surveillance," reads a subhead on the article, citing a bug report which notes, among other things, the potential for man-in-the-middle attacks and the fact that the Netherlands hosts a major internet transit point' -- source: https://tech.slashdot.org/story/17/11/05/1845240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Lots Of Digitally-Signed Malware Out There
by Lawrence D'Oliveiro 03 Nov '17

03 Nov '17

One of the security weaknesses exploited by the “Stuxnet” worm that sabotaged Iran’s nuclear enrichment program was that it had a valid digital signature from a recognized issuer of certificates for Windows software. Of course, the issuer would never knowingly have validated a piece of malware, but the certificate had been compromised so it could be used without their permission. Turns out this sort of thing is not only quite common, there is a further problem in that anti-malware software, which is supposed to pick up revoked certificates and reject signatures that use them, frequently has bugs in their implementation of the signature-checking protocol, so they can let these bad signatures through. <https://arstechnica.com/information-technology/2017/11/evasive-code-signed-…>

The Patent That Just Wouldn’t Die
by Lawrence D'Oliveiro 03 Nov '17

03 Nov '17

A holding company called Personal Audio claims to have a patent covering the entire idea of podcasting. Over the years, it has succeeded in winning some lucrative payouts, including $8 million from Apple and $1.3 million from CBS. All without making a single item of product itself. In other words, Personal Audio is what lawyers politely refer to as a “Non-Practising Entity” (NPE), or, in more common parlance, a patent troll. However, the Electronic Frontier Foundation has succeeded, with the help of a crowdfunding campaign, in invalidating this patent, using a system introduced at the USPTO called “inter partes review” (IPR). Of course, Personal Audio has not taken this lying down. It has come up with a truly imaginative series of legal counterarguments: * IPR violates the 7th Amendment of the US Constitution (right to trial by jury in a lawsuit). * IPR encourages “collective efforts to invalidate patents” which “severely tilts the playing field in favor of the party or parties seeking invalidation”. * the EFF has been working together with defendants in their litigation. Fortunately, the Court of Appeals for the Federal Circuit (CAFC) -- the same appeals court that overruled Judge William Alsup in his verdict (in Oracle vs Google) that APIs were not copyrightable -- seems to be a bit less uncritically pro-“Intellectual Property” these days (something to do with being slapped down by the Supreme Court?), and has rejected these arguments. Imagine if all this creativity had gone into producing actual useful products, instead of legal arguments ... <https://arstechnica.com/tech-policy/2017/11/eff-destroys-the-podcasting-pat…>

Android Oreo Bug Sends Thousands of Phones Into Infinite Boot Loops
by Peter Reutemann 02 Nov '17

02 Nov '17

'A bug in the new "Adaptive Icons" feature introduced in Android Oreo has sent thousands of phones into infinite boot loops, forcing some users to reset their devices to factory settings, causing users to lose data along the way. The bug was discovered by Jcbsera, the developer of the Swipe for Facebook Android app (energy-efficient Facebook wrapper app), and does not affect Android Oreo (8.0) in its default state. The bug occurs only with apps that use adaptive icons -- a new feature introduced in Android Oreo that allows icons to change shape and size based on the device they're viewed on, or the type of launcher the user is using on his Android device. For example, adaptive icons will appear in square, rounded, or circle containers depending on the theme or launcher the user is using. The style of adaptive icons is defined a local XML file. The bug first manifested itself when the developer of the Swipe for Facebook Android app accidentally renamed the foreground image of his adaptive icon with the same name as this XML file (ic_launcher_main.png and ic_launcher_main.xml). This naming scheme sends Android Oreo in an infinite loop that regularly crashes the device. At one point, Android detects something is wrong and prompts the user to reset the device to factory settings. Users don't have to open an app, and the crashes still happen just by having an app with malformed adaptive icons artifacts on your phone. Google said it will fix the issue in Android Oreo 8.1.' -- source: https://tech.slashdot.org/story/17/11/01/1550256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How Kodi Took Over Piracy
by Peter Reutemann 30 Oct '17

30 Oct '17

'For years, piracy persisted mainly in the realm of torrents, with sites like The Pirate Bay and Demonoid connecting internet denizens to premium content gratis. But a confluence of factors have sent torrent usage plummeting from 23 percent of all North American daily internet traffic in 2011 to under 5 percent last year. Legal crackdowns shuttered prominent torrent sites. Paid alternatives like Netflix and Hulu made it easier just to pay up. And then there were the "fully loaded" Kodi boxes -- otherwise vanilla streaming devices that come with, or make easily accessible, so-called addons that seek out unlicensed content -- that deliver pirated movies and TV shows with push-button ease. "Kodi and the plugin system and the people who made these plugins have just dumbed down the process," says Dan Deeth, spokesperson for network-equipment company Sandvine. "It's easy for anyone to use. It's kind of set it and forget it. Like the Ron Popeil turkey roaster." Kodi itself is just a media player; the majority of addons aren't piracy focused, and lots of Kodi devices without illicit software plug-ins are utterly uncontroversial. Still, that Kodi has swallowed piracy may not surprise some of you; a full six percent of North American households have a Kodi device configured to access unlicensed content, according to a recent Sandvine study. But the story of how a popular, open-source media player called XBMC became a pirate's paradise might. And with a legal crackdown looming, the Kodi ecosystem's present may matter less than its uncertain future.' -- source: https://yro.slashdot.org/story/17/10/30/1931208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

If We Can’t Trust Kaspersky, Should We Trust Microsoft?

An opinion piece at Al Jazeera <http://www.aljazeera.com/indepth/opinion/trust-kaspersky-trust-microsoft-17…> considers: A single malicious update pushed from Microsoft could cripple almost every government worldwide. ... That a small number of vendors have the capacity to remotely shut down government infrastructure, or vacuum up secret documents, is almost too scary to wrap your head around. And that's without pondering how likely they are to be pressured by their governments. In the face of future conflict, is the first step going to be disabling auto-updates for software from that country?

Early HP Archives Destroyed
by Lawrence D'Oliveiro 30 Oct '17

30 Oct '17

Bill Hewlett and Dave Packard were the archetypal “two guys who started a business in a garage” from 1938. When the company they founded moved on to other things (computers, printers etc), the original test-equipment business they created was spun off as part of a company called Agilent, which in turn divested it as an outfit now known as Keysight. Now we hear that important historical paper archives from those early days, which were in the care of Keysight Technologies, have been lost in the recent deadly Santa Rosa wildfires. <http://www.theregister.co.uk/2017/10/29/hewlett_packard_history_lost_to_san…>

Anypaste – Share And Upload Files To Compatible Hosting Sites Automatically
by Peter Reutemann 30 Oct '17

30 Oct '17

'A while ago, we have written a guide about Transfer.sh which allows you to share files over Internet from command-line. Today, we will see yet another file sharing utility called Anypaste. It is a simple script to share and upload files to compatible hosting sites depending upon the type of the files, automatically. You don’t need to manually log in to the hosting sites and upload or share your files. Anypaste will pick the right hosting sites depends upon the type of the file you want to upload. To put this simply, photos will get uploaded to image hosting sites, videos to video sites, code to pastebins. Cool, yeah? Anypaste is completely free, open source and light-weight script and you can do everything from command line. You don’t need to depend on any heavy, memory-consuming GUI apps to upload and share files.' -- source: https://www.ostechnix.com/anypaste-share-upload-files-compatible-hosting-si… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Purism Now Offers Laptops with Intel's 'Management Engine' Disabled
by Peter Reutemann 29 Oct '17

29 Oct '17

' "San Francisco company Purism announced that they are now offering their Librem laptops with the Intel Management Engine disabled," writes Slashdot reader boudie2. Purism describes Management Engine as "a separate CPU that can run and control a computer even when powered off." HardOCP reports that Management Engine "is widely despised by security professionals and privacy advocates because it relies on signed and secret Intel code, isn't easily alterable, isn't fully documented, and has been found to be vulnerable to exploitation... In short, it's a tiny potentially hackable computer in your computer that you cannot totally control, nor opt-out of, but it can totally control your system." Purism writes: Disabling the Management Engine is no easy task, and it has taken security researchers years to find a way to properly and verifiably disable it. Purism, because it runs coreboot and maintains its own BIOS firmware update process, has been able to release and ship coreboot that disables the Management Engine from running, directly halting the ME CPU without the ability of recovery... "Disabling the Management Engine, long believed to be impossible, is now possible and available in all current Librem laptops. It is also available as a software update for previously shipped recent Librem laptops," says Todd Weaver, Founder & CEO of Purism.' -- source: https://hardware.slashdot.org/story/17/10/29/0324201 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Mint Is Killing the KDE Edition
by Peter Reutemann 27 Oct '17

27 Oct '17

'While both the Cinnamon and Mate versions of Linux Mint are decent choices for computer users, there was one version that was always utterly bizarre -- the KDE Edition. Don't get me wrong, KDE is a fine environment, but Kubuntu already exists. Having a version of Mint using KDE was redundant and confusing. Thankfully, today, the Linux Mint team announces it is finally killing the KDE edition. "In continuation with what's been done in the past, Linux Mint 18.3 will feature a KDE edition, but it will be the last release to do so. I would like to thank Kubuntu for the amazing work they have done. The quality of Plasma 5 in Xenial made backports a necessity. The rapid pace of development upstream from the KDE project made this very challenging, yet they managed to provide a stable flow of updates for us and we were able to ship good KDE editions thanks to that. I don't think this would have been possible without them," says Clement Lefebvre, Linux Mint. Lefebvre further says, "KDE is a fantastic environment but it's also a different world, one which evolves away from us and away from everything we focus on. Their apps, their ecosystem and the QT toolkit which is central there have very little in common with what we're working on. We're not just shipping releases and distributing upstream software. We're a product distribution and we see ourselves as a complete desktop operating system. We like to integrate solutions, develop whatâ(TM)s missing, adapt what's not fitting perfectly, and we do a great deal of that not only around our own Cinnamon desktop environment but also thanks to cross-DE frameworks we put in place to support similar environments, such as MATE and Xfce."' -- source: https://linux.slashdot.org/story/17/10/26/0325221 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Who's building Linux in 2017?

'It's 2017 and Linux rules the computing world. Don't believe me? The Linux Foundation reports that Linux runs 90 percent of the public cloud workload, 82 percent of the world's smartphones, 62 percent of the embedded market, oh and a mere 99 percent of the supercomputer market. All that rests on the Linux kernel. In its 2017 Linux Kernel Development Report, Jonathan Corbet, Linux kernel developer and editor of LWN.net, and Greg Kroah-Hartman, stable Linux kernel maintainer, report on Linux's recent evolution. This report was released at the invitation-only Linux Kernel Summit in Prague, Czech Republic. Since 2005 and adoption of Git version control system, 15,637 developers from over 1,400 companies have contributed to the Linux kernel. Since last year, over 4,300 developers from more than 500 companies have contributed to the kernel. Of these, 1,670 contributed for the first time, or about a third of contributors' -- source: http://www.zdnet.com/article/whos-building-linux-in-2017/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Are “Enterprise-Quality” Hard Drives Worth It?
by Lawrence D'Oliveiro 26 Oct '17

26 Oct '17

Another quarter, another report from backups outfit Backblaze on hard disk reliability <https://arstechnica.com/gadgets/2017/10/big-hard-disks-may-be-breaking-the-…>: In aggregate, the company has now accumulated 3.7 million drive days for the consumer disks and 1.4 million for the enterprise ones. Over this usage, the annualized failure rates are 1.1 percent for the consumer disks and 1.2 percent for the enterprise ones. At least for now, then, the enterprise disks aren't doing anything to justify their longer warranty; their reliability is virtually identical.

Why Did Ubuntu Drop Unity? Mark Shuttleworth Explains
by Peter Reutemann 24 Oct '17

24 Oct '17

Since we talked about Canonical ditching Mir/Unity on Monday night, here's some more insight from Shuttleworth himself: 'Ubuntu's decision to ditch Unity took many of us by surprise earlier this year. Now Ubuntu founder Mark Shuttleworth shares more details about why Ubuntu chose to drop Unity. From a report: Shuttleworth says he, along with the other 'leads' at Canonical, came to a consensual view that they should put the company on the path to becoming a public company. And to appear attractive to potential investors the company has to focus on its areas of profitability -- something Unity, Ubuntu phone, Unity 8 and convergence were not part of: "[The decision] meant that we couldn't have on our books (effectively) very substantial projects which clearly have no commercial angle to them at all. It doesn't mean that we would consider changing the terms of Ubuntu for example, because it's foundational to everything we do. And we don't have to, effectively," he said. Money may have meant Unity's demise but the wider Ubuntu project is in rude health. as Shuttleworth explains: "One of the things I'm most proud of is in the last 7 years is that Ubuntu itself became completely sustainable. I could get hit by a bus tomorrow and Ubuntu could continue. It's kind of magical, right? Here's a platform that is a world class enterprise platform, that's completely freely available, and yet it is sustainable. Jane Silber is largely to thank for that." While it's all-too-easy for desktop users to focus on, well, the desktop, there is far more to Canonical (the company) than the 6-monthly releases we look forward to. Losing Unity may have been a big blow for desktop users but it helped to balance other parts of the company: "There are huge possibilities for us in the enterprise beyond that, in terms of really defining how cloud infrastructure is built, how cloud applications are operated, and so on. And, in IoT, looking at that next wave of possibility, innovators creating stuff on IoT. And all of that is ample for us to essentially put ourselves on course to IPO around that." Dropping Unity wasn't easy for Mark, though: "We had this big chunk of work, which was Unity, which I really loved. I think the engineering of Unity 8 was pretty spectacularly good, and the deep ideas of how you bring these different form factors together was pretty beautiful.' -- source: https://news.slashdot.org/story/17/10/24/1854254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Librem 5 Privacy-Focused Linux Phone Crowdfunding Campaign Ends with $2 Million
by Peter Reutemann 24 Oct '17

Since we talked about this phone last night... 'Librem 5 was successfully crowdfunded about two weeks ago when it surpassed its goal of $1.5 million, but the campaign continued to run, and now it appears to have gathered half million dollars more, ending with $2 million, which we believe is more than enough to build world's first truly free mobile device. Powered by PureOS, Purism's own GNU/Linux distribution based on the popular Debian GNU/Linux operating system, but focused on offering users a privacy-focused and more secure desktop solution, Librem 5 will be using KDE's Plasma Mobile and GNOME's GNOME Shell user interfaces, along with powerful open source software. During its crowdfunding campaign, Librem 5 saw an amazing feedback from the Open Source community as Purism partnered not only with big names like KDE and GNOME, but also with Nextcloud, which will bring its end-to-end encrypted file sync, sharing and cloud-based storage solution by default to the Linux smartphone.' -- source: http://news.softpedia.com/news/librem-5-privacy-focused-linux-phone-crowdfu… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Why Computing Devices Slow Down Over Time
by Lawrence D'Oliveiro 23 Oct '17

23 Oct '17

Entertaining opinion piece <http://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=11935838>: To make their apps run faster, some designers make them store copies of things in RAM ... Known as cacheing, this makes things work much faster - until your system starts to run out of memory. For cacheing to be effective, the amount of space devoted to it must be carefully managed by the application and the device's operating system. Some app developers don't put the effort that they should into doing this well, and their applications not only slow down over time, but can drag the rest of the system down with them too. So trying to speed things up can make things slower??

Android getting “DNS over TLS” support to stop ISPs from knowing what websites you visit
by Peter Reutemann 23 Oct '17

23 Oct '17

'DNS (Domain Name Server) is what translates a website address from a URL that you enter to an IP address which your computer actually connects to. For example, when you type “www.xda-developers.com” into your browser, your computer queries a DNS which looks up and returns the IP address “209.58.128.90” to the client. This process is hidden from the user, but every website you visit (so long as it has a human-readable URL) will go through this same process. The problem for those security conscious out there is that these requests are done in plain text through UDP or TCP protocols which are readable by anyone that can see your connection, including your ISP. This is where DNS over TLS comes in.' -- source: https://www.xda-developers.com/android-dns-over-tls-website-privacy/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft Chastises Google Over Chrome Security
by Peter Reutemann 22 Oct '17

22 Oct '17

'In a Wednesday blog post, Redmond examined Google's browser security and took the opportunity to throw some shade at Chrome's security philosophy, while also touting the benefits of its own Edge browser. The post, written by Microsoft security team member Jordan Rabet, noted that Google's Chrome browser uses "sandboxing" and isolation techniques designed to contain any malicious code. Nevertheless, Microsoft still managed to find a security hole in Chrome that could be used to execute malicious code on the browser. The bug involved a Javascript engine in Chrome. Microsoft notified Google about the problem, which was patched last month. The company even received a $7,500 reward for finding the flaw. However, Microsoft made sure to point out that its own Edge browser was protected from the same kind of security threat. It also criticized Google for the way it handled the patching process. Prior to the patch's official rollout, the source code for the fix was made public on GitHub, a software collaboration site that hosts computer code. That meant attentive hackers could have learned about the vulnerability before the patch was pushed out to customers, Microsoft claimed. "In this specific case, the stable channel of Chrome remained vulnerable for nearly a month," the blog post said. "That is more than enough time for an attacker to exploit it." In the past Google has also disclosed vulnerabilities found in Microsoft products -- including Edge.' -- source: https://it.slashdot.org/story/17/10/22/010235 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

KASLR basically randomizes the address of the kernel, and makes it harder to exploit several classes of vulnerabilities [including privilege escalations and remote code execution]. It is still a work-in-progress, but it's already fully functional, and can be used following the instructions on this post from the NetBSD blog. It will be available starting from NetBSD 9, but may be backported to NetBSD 8 once it is stabilized.

Bloody Stupid Linux
by Lawrence D'Oliveiro 21 Oct '17

21 Oct '17

That’s the name of the distro <http://bloodystupid.clockwatching.org/>: Why go to all this trouble? The BSL kernel is basically a life support system for ram and network cards, since it wget's support for everything else on the machine the kernel is very small. The initial aim was to fit it on a single floppy, then PXE booting became attractive, and really, since the kernel doesn't need to support whatever it just booted from in order to have its root filesystem, its very flexible. Yeah, I know an initrd can do the same thing, but its more fun this way. As it stands, BSL makes for an excellent repair system, the framework for a bulk installer, a neat toy, and an alright thin client ( as long as you've got a gob of RAM handy.) OK, so it hasn’t been updated in over a decade. But the mascot image is cute. ;)

Canada's 'Super Secret Spy Agency' Is Releasing a Malware-Fighting Tool To the Public
by Peter Reutemann 19 Oct '17

19 Oct '17

'Canada's electronic spy agency says it is taking the "unprecedented step" of releasing one of its own cyber defence tools to the public, in a bid to help companies and organizations better defend their computers and networks against malicious threats. The Communications Security Establishment (CSE) rarely goes into detail about its activities -- both offensive and defensive -- and much of what is known about the agency's activities have come from leaked documents obtained by U.S. National Security Agency whistleblower Edward Snowden and published in recent years. But as of late, CSE has acknowledged it needs to do a better job of explaining to Canadians exactly what it does. Today, it is pulling back the curtain on an open-source malware analysis tool called Assemblyline that CSE says is used to protect the Canadian government's sprawling infrastructure each day. "It's a tool that helps our analysts know what to look at, because it's overwhelming for the number of people we have to be able to protect things," Scott Jones, who heads the agency's IT security efforts, said in an interview with CBC News. On the one hand, open sourcing Assemblyline's code is a savvy act of public relations, and Jones readily admits the agency is trying to shed its "super secret spy agency" reputation in the interest of greater transparency.' -- source: https://news.slashdot.org/story/17/10/19/1837236 Let's see, whether anybody finds bits in the code that report home to the agency...

EU: No Encryption Backdoors But, Let's Help Each Other Crack That Crypto
by Peter Reutemann 19 Oct '17

19 Oct '17

'The European Commission has proposed that member states help each other break into encrypted devices by sharing expertise around the bloc. From a report: In an attempt to tackle the rise of citizens using encryption and its effects on solving crimes, the commission decided to sidestep the well-worn, and well-ridiculed, path of demanding decryption backdoors in the stuff we all use. Instead, the plans set out in its antiterrorism measures on Wednesday take a more collegiate approach -- by offering member states more support when they actually get their hands on an encrypted device. "The commission's position is very clear -- we are not in favour of so-called backdoors, the utilisation of systemic vulnerabilities, because it weakens the overall security of our cyberspace, which we rely upon," security commissioner Julian King told a press briefing. "We're trying to move beyond a sometimes sterile debate between backdoors or no backdoors, and address some of the concrete law enforcement challenges. For instance, when [a member state] gets a device, how do they get information that might be encrypted on the device." [...] Share the wealth. "Some member states are more equipped technically to do that [extract information from a seized device] than others," King said.

Google Engineers Explore Ways To Stop In-Browser Cryptocurrency Miners in Chrome
by Peter Reutemann 19 Oct '17

19 Oct '17

'Google Chrome engineers are considering adding a special browser permission that will thwart the rising trend of in-browser cryptocurrency miners. Discussions on the topic of in-browser miners have been going on the Chromium project's bug tracker since mid-September when Coinhive, the first such service, launched. "Here's my current thinking," Ojan Vafai, a Chrome engineering working on the Chromium project, wrote in one of the recent bug reports. "If a site is using more than XX% CPU for more than YY seconds, then we put the page into 'battery saver mode' where we aggressively throttle tasks and show a toast [notification popup] allowing the user to opt-out of battery saver mode. When a battery saver mode tab is backgrounded, we stop running tasks entirely. I think we'll want measurement to figure out what values to use for XX and YY, but we can start with really egregious things like 100% and 60 seconds. I'm effectively suggesting we add a permission here, but it would have unusual triggering conditions [...]. It only triggers when the page is doing a likely bad thing." An earlier suggestion had Google create a blacklist and block the mining code at the browser level. That suggestion was shut down as being too impractical and something better left to extensions.' -- source: https://tech.slashdot.org/story/17/10/19/1618222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Targeted Fuzzing Is Improving Linux Security, Linus Torvalds Says
by Peter Reutemann 19 Oct '17

19 Oct '17

'On the sidelines of announcing the fifth release candidate for the Linux kernel version 4.14, Linus Torvalds said fuzzing, which involves stress testing a system by generating random code to induce errors, is helping the community find and fix a range of security vulnerabilities. He wrote: The other thing perhaps worth mentioning is how much random fuzzing people are doing, and it's finding things. We've always done fuzzing (who remembers the old "crashme" program that just generated random code and jumped to it? We used to do that quite actively very early on), but people have been doing some nice targeted fuzzing of driver subsystems etc, and there's been various fixes (not just this last week either) coming out of those efforts. Very nice to see.' -- source: https://linux.slashdot.org/story/17/10/19/171206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

IoT Cybersecurity: What’s Plan B?
by Lawrence D'Oliveiro 19 Oct '17

19 Oct '17

Whither the Internet Of Things? Markets, as we've repeatedly learned over the past century, are terrible mechanisms for improving the safety of products and services. It was true for automobile, food, restaurant, airplane, fire, and financial-instrument safety. The reasons are complicated, but basically, sellers don't compete on safety features because buyers can't efficiently differentiate products based on safety considerations. The race-to-the-bottom mechanism that markets use to minimize prices also minimizes quality. Without government intervention, the IoT remains dangerously insecure. The US government has no appetite for intervention, so we won't see serious safety and security regulations, a new federal agency, or better liability laws. We might have a better chance in the EU. Depending on how the General Data Protection Regulation on data privacy pans out, the EU might pass a similar security law in 5 years. No other country has a large enough market share to make a difference. <https://www.schneier.com/blog/archives/2017/10/iot_cybersecuri.html>

GPL Abuse In The Linux Kernel
by Lawrence D'Oliveiro 18 Oct '17

18 Oct '17

The questionable legal activities of a former Linux kernel developer <http://www.theregister.co.uk/2017/10/18/linux_kernel_community_enforcement_…> have driven a bunch of senior kernel figures to issue a “Community Enforcement Statement” to try to put a stop to this sort of thing in the future. What’s interesting about this is their admission that the GPL 2.0 has “ambiguities … that no one in our community has ever considered part of compliance”. And to fix it, their Statement “adopts the same termination provisions we are all familiar with from GPL-3.0 as an Additional Permission giving companies confidence that they will have time to come into compliance if a failure is identified”. Do you remember back when GPL 3.0 came out, and Linus Torvalds and other senior kernel figures issued a statement claiming that they were quite happy with GPL 2.0, they had no intention of moving to GPL 3.0, which he quite publicly loathed? Seems like now they are slowly coming to a realization of the reasons why GPL 3.0 was created in the first place...

Ah, The Joys Of Debian Unstable ...
by Lawrence D'Oliveiro 17 Oct '17

17 Oct '17

Did my (roughly) monthly system upgrades over the last couple of days. Debian has changed the default Python version for the “python3” command to 3.6. (And Blender now requires that version for building as well.) Didn’t notice anything broken until today, when I tried to print something on my HP inkjet. Turns out the various HP/CUPS-related packages with version number 3.17 want the system default Python to be 3.5, not 3.6. In situations like these, the first thing I have learned to try is to manually download older versions of packages from <http://ftp.debian.org/debian/> and install them with “dpkg -i”. For reference, these are the packages I downgraded: dpkg -i hplip-data_3.16.11+repack0-3_all.deb dpkg -i libhpmud0_3.16.11+repack0-3_amd64.deb dpkg -i libsane-hpaio_3.16.11+repack0-3_amd64.deb dpkg -i printer-driver-hpcups_3.16.11+repack0-3_amd64.deb dpkg -i hplip_3.16.11+repack0-3_amd64.deb And it worked. My printer now prints again. Presumably this will be sorted out in time for my next upgrade ...

qTox – An Open Source P2P Instant Messaging and VoIP App
by Peter Reutemann 16 Oct '17

16 Oct '17

'As you probably already know, GNU/Linux has no shortage of VoIP apps. We’ve written on Wire and Discord. And we even compiled a list of The 10 Best Instant Messaging Apps for Linux. Today, we’ve got a new app to add to our list of instant messaging apps and it goes by the name of qTox. qTox is a free and open source p2p instant messaging, audio and video calls app and is (apparently) the most feature-rich Tox client. As a powerful Tox client, it follows Tox’s design guidelines while maintaining a uniform UI/UX across all the major platforms. It is built with privacy as its paramount goal and the team has even made a public statement that user safety is their priority and nothing in the world can change that.' -- source: https://www.fossmint.com/qtox-an-open-source-p2p-instant-messaging-and-voip… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

by Peter Reutemann 16 Oct '17

16 Oct '17

'Interested in running Linux on Windows 10 with Windows Subsystem for Linux (WSL), but nervous about it being both a beta and only available in Windows 10 developer mode? Your worries are over. In the Windows 10 Fall Creators Update (WinFCU) WSL has graduated to being a Windows 10 feature that can be run by any user. Tested for over a year, WSL on WinFCU is bringing many new features to this combination of the Linux Bash shell and Windows. Besides WSL no longer being a beta or requiring users to be in developer mode, the new features include: Install Linux distros via the Windows Store - WSL now runs multiple Linux distros - WSL comes to Windows Server & Microsoft Azure VMs - WSL now supports USB/serial comms - Miscellaneous fixes and improvements Besides Ubuntu, the new WSL-supported Linux distros are SUSE's community openSUSE and its corporate SUSE Linux Enterprise Server (SLES). Fedora and other distros will arrive in the store shortly.' -- source: http://www.zdnet.com/article/windows-subsystem-for-linux-graduates-in-windo… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
