Insurance Companies Recommending Computer Gear?
by Lawrence D'Oliveiro 07 Feb '18

07 Feb '18

A couple of big insurance outfits have made deals with Apple and Cisco to charge lower cybersecurity premiums to customers buying their gear <http://www.theregister.co.uk/2018/02/06/cisco_apple_allianz_aon_cyber_insur…>. 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firm Radware, the group is building the botnet by exploiting two vulnerabilities: one in RealTek routers running out-of-date firmware and the other in the Huawei HG532 router, where a patch released in December has yet to be installed by many users.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

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 Released: Features Superior Microsoft Office Interoperability, OpenPGP Support
by Peter Reutemann 31 Jan '18

31 Jan '18

'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

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/

Is This The Hawaii Civil Defence Missile Alert UI?
by Lawrence D'Oliveiro 30 Jan '18

30 Jan '18

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. Porup cites the work of Ilja von Sprundel, director of penetration testing at IOActive, who, noting the "small number of reported BSD kernel vulnerabilities compared to Linux," dug into BSD source code. His search 'easily' turned up about 115 kernel bugs. Porup looks at the relative security of OpenBSD, FreeBSD and NetBSD, the effect on Mac OS, and why, despite FreeBSD's relative popularity, OpenBSD may be the most likely to survive.' -- source: https://bsd.slashdot.org/story/18/01/26/1636229 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.

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

'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

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/

“Kernel Memory Leaking” Intel Processor Design Flaw Forces Linux, Windows Redesign
by Lawrence D'Oliveiro 20 Jan '18

20 Jan '18

A pretty serious-sounding security hole has been found in recent Intel CPUs, which will require performance-sapping workarounds in both Linux and Windows to fix <http://www.theregister.co.uk/2018/01/02/intel_cpu_design_flaw/>. The details are not public yet, but AMD, in its announcement that its products are not affected, would seem to have divulged some important clues.

Trying To Fix Windows Security Problems Breaks Security Software
by Lawrence D'Oliveiro 20 Jan '18

20 Jan '18

Microsoft is having a tough time coming out with good patches for the Spectre and Meltdown vulnerabilities. The main trouble is, these patches cause third-party anti-malware software to malfunction, and so the vendors of those products have to rush out their own patches to work with the fixes <http://www.theregister.co.uk/2018/01/08/meltdown_fix_security_problems/>.

Introducing The Cryptocurrency-Mining Operating System
by Lawrence D'Oliveiro 19 Jan '18

Mentioned in passing in this article <https://arstechnica.com/tech-policy/2018/01/cryptocurrency-boom-creates-ins…> explaining why high-end graphics cards are currently in short supply (they’re being snapped up by cryptocurrency miners) is the existence of a “mining-centric operating system called PIMP OS”. Presumably they’re Linux-based, I thought. And checking the T&Cs <https://getpimp.org/terms/> reveals yes, it’s built on Debian, with a bunch of other pieces, some closed-source, some open.

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
by Peter Reutemann 17 Jan '18

17 Jan '18

'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/

'Ubuntu Xenial 16.04 users who updated to receive the Meltdown and Spectre patches are reporting they are unable to boot their systems and have been forced to roll back to an earlier Linux kernel image. The issues were reported by a large number of users on the Ubuntu forums and Ubuntu's Launchpad bug tracker. Only Ubuntu users running the Xenial 16.04 series appear to be affected. All users who reported issues said they were unable to boot after upgrading to Ubuntu 16.04 with kernel image 4.4.0-108. Canonical, the company behind Ubuntu OS, deployed Linux kernel image 4.4.0-108 as part of a security update for Ubuntu Xenial 16.04 users, yesterday, on January 9.

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/

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.
