Linux 4.11 Delayed For a Week
by Peter Reutemann 26 Apr '17

26 Apr '17

'Linux kernel creator Linus Torvalds said over the weekend that v4.11 version of Linux has hit a speed bump in the form of "NVMe power management that apparently causes problems on some machines." The Register adds: "It's not entirely clear what caused the [NVMe] issue (it wasn't just limited to some NVMe hardware, but also particular platforms), but let's test it." Which sounds like a good idea, given that flash memory on the PCIe bus is increasingly mainstream. That problem and "a couple of really annoying" bugs mean that Torvalds has decided to do an eighth release candidate for Linux 4.11. "I did get fixes for the issues that popped up, so I could have released 4.11 as-is," Torvalds wrote, "but it just doesn't feel right."' -- source: https://linux.slashdot.org/story/17/04/24/1633209 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/

Canadian Regulator Puts Foot Down On Net Neutrality
by Lawrence D'Oliveiro 23 Apr '17

23 Apr '17

While the Trump administration has rolled back consumer protections on net neutrality in the USA, the Canadian CRTC has come out firmly in favour of it <https://www.theregister.co.uk/2017/04/21/canada_net_neutrality/>. It has said that “zero rating”--the practice of ISPs favouring certain online services by not counting them towards data caps, is bad because differential pricing practices, generally speaking, result in (a) a preference toward certain subscribers over others, (b) a preference toward certain content providers over others, (c) a disadvantage to subscribers who are not eligible for, or interested in, a differential pricing practice offering, and (d) a disadvantage to content providers that are not eligible for, or included in, an offering. In other words, they are anticompetitive, no matter what some may try to argue.

File System Improvements To the Windows Subsystem for Linux
by Peter Reutemann 21 Apr '17

21 Apr '17

'In the latest Windows Insider build, the Windows Subsystem for Linux (WSL) now allows you to manually mount Windows drives using the DrvFs file system. Previously, WSL would automatically mount all fixed NTFS drives when you launch Bash, but there was no support for mounting additional storage like removable drives or network locations. Now, not only can you manually mount any drives on your system, we've also added support for other file systems such as FAT, as well as mounting network locations. This enables you to access any drive, including removable USB sticks or CDs, and any network location you can reach in Windows all from within WSL.' -- source: https://tech.slashdot.org/story/17/04/20/1422256 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/

demo at meeting on Monday
by Ian Young 17 Apr '17

17 Apr '17

Afraid I won't be talking about Unity as Ian S has suggested - I have only ever used it briefly and never really quite got what it was all about. However if there is any spare time I could bring a DVB-T card for use with laptops I got recently. It seems to be a live one, lights up and is seen by a laptop and various Linux software applications for viewing TV. Alas, not scanning any channels. Perhaps someone knows all about this, or at any rate more than I do. The device in question is badged as an HP EC300 and has a DIBcom chipset. ~ Ian Y

Dozens Of Canonical Employees Resign As Ubuntu Switches To GNOME, Shuttleworth Returns As CEO
by Peter Reutemann 12 Apr '17

12 Apr '17

'More than 80 Canonical workers are facing the axe as founder Mark Shuttleworth has taken back the role of chief executive officer. The number, revealed today by The Reg, comes as Shuttleworth assumed the position from CEO of eight years Jane Silber, previously chief operating officer. The Reg has learned 31 or more staffers have already left the Ubuntu Linux maker ahead of Shuttleworth's rise, with at least 26 others now on formal notice and uncertainty surrounding the remainder. One individual has resigned while others, particularly in parts of the world with more stringent labour laws (such as the UK), are being left in the dark. The details come after The Reg revealed plans for the cuts as a commercial get-fit programme instituted by Shuttleworth. The Canonical founder is cutting numbers after an external assessment of his company by potential new financial backers found overstaffing and that projects lacked focus.' -- source: https://news.slashdot.org/story/17/04/12/1844230 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 Kodi Development Team Wants To Be Legitimate and Bring DRM To the Platform
by Peter Reutemann 11 Apr '17

11 Apr '17

'The XBMC/ Kodi development team has taken a lot of heat over the years, mostly due to third-party developers introducing piracy plugins to the platform. In many cases, cheap Android computers are often sold with these plugins pre-installed with the Kodi or XBMC name attached to them -- something that caused Amazon to ban sales of such devices. The Kodi team is not happy about this, and has taken the fight to the sellers. The Kodi team is now trying to work with rights holders to introduce DRM and legitimate plugins to the platform. Is this the first step towards creating a true one-stop do it yourself Linux entertainment system?' -- source: https://yro.slashdot.org/story/17/04/11/1911215 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/

Canonical Founder Criticizes Free Software Developers Who 'Hate On Whatever's Mainstream'
by Peter Reutemann 10 Apr '17

10 Apr '17

'Canonical Founder Mark Shuttleworth said Saturday that "I came to be disgusted with the hate" on Canonical's display server Mir, saying it "changed my opinion of the free software community." After announcing his company was abandoning Unity for GNOME, Shuttleworth posted a gracious thank-you note to the Unity community Friday on Google Plus. But on Saturday, he added a sharper comment: "I used to think that it was a privilege to serve people who also loved the idea of service, but now I think many members of the free software community are just deeply anti-social types who love to hate on whatever is mainstream. When Windows was mainstream they hated on it. Rationally, Windows does many things well and deserves respect for those. And when Canonical went mainstream, it became the focus of irrational hatred too. The very same muppets would write about how terrible it was that IOS/Android had no competition and then how terrible it was that Canonical was investing in (free software!) compositing and convergence. Fuck that shit." The comment begins by saying "The whole Mir hate-fest boggled my mind - it's free software that does something invisible really well. It became a political topic as irrational as climate change or gun control, where being on one side or the other was a sign of tribal allegiance. We have a problem in the community when people choose to hate free software instead of loving that someone cares enough to take their life's work and make it freely available."' -- source: https://news.slashdot.org/story/17/04/09/1829209 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/

Android devices can be fatally hacked by malicious Wi-Fi networks
by Peter Reutemann 06 Apr '17

06 Apr '17

'A broad array of Android phones is vulnerable to attacks that use booby-trapped Wi-Fi signals to achieve full device takeover, a researcher has demonstrated. The vulnerability resides in a widely used Wi-Fi chipset manufactured by Broadcom and used in both iOS and Android devices. Apple patched the vulnerability with Monday's release of iOS 10.3.1. "An attacker within range may be able to execute arbitrary code on the Wi-Fi chip," Apple's accompanying advisory warned. In a highly detailed blog post published Tuesday, the Google Project Zero researcher who discovered the flaw said it allowed the execution of malicious code on a fully updated 6P "by Wi-Fi proximity alone, requiring no user interaction." Google is in the process of releasing an update in its April security bulletin. The fix is available only to a select number of device models, and even then it can take two weeks or more to be available as an over-the-air update to those who are eligible. Company representatives didn't respond to an e-mail seeking comment for this post.' -- source: https://arstechnica.com/security/2017/04/wide-range-of-android-phones-vulne… 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/

Canonical Killing Unity For Ubuntu Linux, Will Switch To the Superior GNOME

'Today, the company admits that it is throwing in the towel on Unity, as well as its vision for convergence with devices like phones and tablets.

"We are wrapping up an excellent quarter and an excellent year for the company, with performance in many teams and products that we can be proud of. As we head into the new fiscal year, it's appropriate to reassess each of our initiatives. I'm writing to let you know that we will end our investment in Unity8, the phone and convergence shell.

Samsung’s Tizen is riddled with security flaws, amateurishly written

Like Android, it's built on a Linux kernel, with a large chunk of open source software running on top.

Fuchsia: Google's new operating system
by Bryan Baldwin 04 Apr '17

04 Apr '17

Fuchsia is a new operating system <https://lwn.net/SubscriberLink/718267/206c8a5fbf0ee2ea/> being built more or less from scratch at Google. The news of the development of Fuchsia made a splash on technology news sites in August 2016, although many details about it are still a mystery. It is an open-source project; development and documentation work is still very much ongoing. Despite the open-source nature of the project, its actual purpose has not yet been revealed by Google. From piecing together information from the online documentation and source code, we can surmise that Fuchsia is a complete operating system for PCs, tablets, and high-end phones. The source to Fuchsia and all of its components is available to download at its source repository <https://fuchsia.googlesource.com/>. If you enjoy poking around experimental operating systems, exploring the innards of this one will be fun. Fuchsia consists of a kernel plus user-space components on top that provide libraries and utilities. There are a number of subprojects under the Fuchsia umbrella in the source repository, mainly libraries and toolkits to help create applications. Fuchsia is mostly licensed under a 3-clause BSD license, but the kernel is based on another project called LK (Little Kernel) <https://github.com/littlekernel/lk> that is MIT-licensed, so the licensing for the kernel is a mix. Third-party software included in Fuchsia is licensed according to its respective open-source license. https://www.osnews.com/story/29747/Fuchsia_Google_s_new_operating_system

The r/place Experiment
by Lawrence D'Oliveiro 04 Apr '17

04 Apr '17

Over the April Fool’s weekend, Reddit, the (in)famous social-media and troll-hangout site, tried something very unusual: they created a blank 1000-by-1000-pixel canvas, and turned their users loose on it to draw whatever they liked. The only restriction was a limit on how quickly any one user could update the image: just 1 pixel every 5 minutes. The resulting time-lapse animation is quite breathtaking to watch <https://arstechnica.com/gaming/2017/04/in-memoriam-reddits-72-hour-live-gra…>. Look at the number of logos and national flags: a battle between the French and German flags gets resolved with the French one running its bars vertically, the German one horizontally, and an EU flag placed at the intersection; another brief skirmish between the Greek and Turkish flags gets resolved with them being placed side by side, joined by a heart. Yes, there are the occasional rude words. But it’s surprising how little of that kind of thing appears--or perhaps it was removed too quickly by competing groups with other fish to fry. Watch the animations a few times; you’ll see something new each time.

GNOME 3.24 Released
by Peter Reutemann 22 Mar '17

22 Mar '17

'GNOME 3.24 just finished its six-month development cycle, and it's now the most advanced stable version of the modern and popular desktop environment used by default in numerous GNU/Linux distributions. It was developed since October 2016 under the GNOME 3.23.x umbrella, during which it received numerous improvements. Prominent new features of the GNOME 3.24 desktop environment include a Night Light functionality that promises to automatically shift the colors of your display to the warmer end of the spectrum after sunset, and a brand-new GNOME Control Center with redesigned Users, Keyboard and Mouse, Online Accounts, Bluetooth, and Printer panels. As for the GNOME apps, we can mention that the Nautilus file manager now lets users browse files as root (system administrator), GNOME Photos imitates Darktable's exposure and blacks adjustment tool, GNOME Music comes with ownCloud integration and lets you edit tags, and GNOME Calendar finally brings the Week view. New apps like GNOME Recipes are also part of this release. The full release notes can be viewed here. Softpedia notes in conclusion: "As mentioned before, it will take at least a couple of weeks for the new GNOME 3.24 packages to land on the stable repositories of your favorite distro, which means that you'll most probably be able to upgrade from GNOME 3.22 when the first point release, GNOME 3.24.1, is out on April 12, 2017."' -- source: https://tech.slashdot.org/story/17/03/22/205210 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 Locks Ryzen, Kaby Lake Users Out of Updates On Windows 7, 8.1
by Peter Reutemann 17 Mar '17

17 Mar '17

'In a move that will shock a lot of people, someone at Microsoft decided to deny Windows 7/8.1 updates to the users of the following CPU architectures: Intel seventh (7th)-generation processors (Kaby Lake); AMD "Bristol Ridge" (Zen/Ryzen); Qualcomm "8996." It's impossible to find any justification for this decision to halt support for the x86 architectures listed above because you can perfectly run MS-DOS on them. Perhaps, Microsoft has decided that the process of foisting Windows 10 isn't running at full steam, so the company created this purely artificial limitation. I expect it to be cancelled soon after a wide backlash from corporate customers. KitGuru notes that users may encounter the following error message when they attempt to update their OS: "Your PC uses a processor that isn't supported on this version of Windows."

Desktop support runs for three years and the server edition receives security patches and updates for a period of five years. Security updates for 12.04 were scheduled to run out on April 28, 2017 but that now won't happen for those on Canonical's Ubuntu Advantage programme. They'll now receive important security fixes for the kernel and "most essential" userspace packages on their servers running 12.04.

An anonymous reader quotes ZDNet: The problem is that most computers automatically trust every USB device that's plugged in, which means malicious code can run without warning... Cars, cash registers, and some ATMs also come with USB ports, all of which can be vulnerable to cyberattacks from a single USB stick. That's where the USG firewall comes in...a simple hardware serial link that only accepts a very few select number of safe commands, which prevents the device from executing system commands or intercepting network traffic. That means the data can flow from the USB device, but [it] effectively blocks other USB exploits. The firmware has been open sourced, and the technical specifications have also been released online "to allow anyone to build their own from readily available development boards."' -- source: https://hardware.slashdot.org/story/17/03/11/1658238 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's IT Lead: 'No Compelling Reason' To Switch Back To Windows From Linux
by Peter Reutemann 12 Mar '17

12 Mar '17

'"The man who runs Munich's central IT says there is no practical reason for the city to write off millions of euros and years of work to ditch its Linux-based OS for Windows," reports TechRepublic. Long-time Slashdot reader Qbertino summarizes a German-language article: Karl-Heinz Schneider, lead of Munich's local system house company IT(a)M, goes on to claim, "We do not see pressing technical reasons to switch to MS and MS Office... The council [in their recent plans] didn't even follow the analysts' suggestion to stick with using LibreOffice." Furthermore, Schneider stated that "System failures that angered citizens in recent years never were related to the LiMux project, but due to new bureaucratic procedures..." and apparently decisions by unqualified personnel at the administrative level, as Munich's administration itself states.' -- source: https://linux.slashdot.org/story/17/03/11/0142247 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 Foundation Chief: Businesses 'Will Fail' If They Don't Use Open Source Code
by Peter Reutemann 12 Mar '17

12 Mar '17

'First Vint Cert said there's a "thread of openness" that runs throughout the internet, adding that "the internet, itself, has open characteristics" and thrives on "permissionless innovation." And Eric Brewer, vice president of infrastructure at Google, touched on the same themes, according to Tech Republic. "Linux, Brewer said, won some of the early internet wars because it was open, but also because it was the most innovative of its time. He also said that companies should work with open source for the value of the ecosystem and community, not just the value of the code." Then Linux Foundation executive director Jim Zemlin told the audience that business models were already changing to include open source, and ultimately made the argument that organizations that "don't harvest the shared innovation" of open source "will fail."

US ISP Verizon Wireless To Stop Giving Out Static IPv4 Addresses
by Lawrence D'Oliveiro 10 Mar '17

10 Mar '17

New business customers with Verizon Wireless will no longer get static IPv4 addresses. Instead, they will get “persistent prefix” IPv6 addresses <https://www.theregister.co.uk/2017/03/10/verizon_running_out_of_ipv4_addres…>. I assume “persistent prefix” means they get a fixed value for the top 48 bits, and they can do what they like with the bottom 80 bits. This /48 subnet allocation seems to be the common thing for IPv6.

The City of Munich Might Stick With Linux
by Peter Reutemann 06 Mar '17

06 Mar '17

'Munich's "LiMux" project brought FOSS software to their city's IT administration -- until a vote last month on whether to abandon Linux and return to Windows. "Since this decision was reached, the majority of media have reported that a final call was made to halt LiMux and switch back to Microsoft software," reports the Free Software Foundation Europe. "This is, however, not an accurate representation of the outcome of the city council meeting." An anonymous reader quotes their report: The opposing parties were overruled, but the decision was amended such that the strategy document must specify which LiMux-applications will no longer be needed, the extent in which prior investments must be written off, and a rough calculation of the overall costs of the desired unification... [Only then will the city council make their final decision...] We succeeded thus far in forcing the mayor Dieter Reiter to postpone the final decision, and this was possible through the unwavering pressure created by joint efforts between The Document Foundation, KDE, OSBA, and the FSFE together with all the individuals who wrote to city council members and took the issue to the media. Although the mandate is highly suggestive in that it suggests that the existing vendor-neutral approach is to be replaced with a proprietary solution, it leaves the door open... The new mandate buys us some time. And we will keep going. Some politicians said they'd never received this much input from the public before, and the Free Software Foundation Europe says the city's issues were caused "from organizational problems, including lack of clear structures and responsibilities," which should not be attributed to the Linux operating system. "LiMux as such is still one of the best examples of how to create a vendor-neutral administration based on Free Software."' -- source: https://linux.slashdot.org/story/17/03/04/0532214 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/

CSS font-size parameter
by Ian Stewart 27 Feb '17

27 Feb '17

Hi All, There was discussion at last nights meeting regarding the CSS "font-size" property and which units to use. E.g. px (pixels), % (percentage), pt (point), or em (a unit in the field of typography originally based on the width of an "M"), . Note that there are more than just these four units, see here<https://www.w3.org/Style/Examples/007/units.en.html>. If you buy-off on the statements from w3schools.com, then this<http://%20https://www.w3schools.com/TAgs/ref_pxtoemconversion.asp> web-page provides a pixel to em converter, and to quote from their CSS page<https://www.w3schools.com/css/css_font.asp>... "Note: If you do not specify a font size, the default size for normal text, like paragraphs, is 16px (16px=1em)." "The em size unit is recommended by the W3C. 1em is equal to the current font size. The default text size in browsers is 16px. So, the default size of 1em is 16px. The size can be calculated from pixels to em using this formula: pixels/16=em." Although admitting there is much debate over which is the better approach, Kyle Schaeffer, on his website<http://kyleschaeffer.com/development/css-font-size-em-vs-px-vs-pt-vs/>, adds in an addendum from 2011... "Generally, when I create a new design, I will use percent on the body element (body { font-size: 62.5%; }), and then use the em unit to size it from there." Or, for some quotes from wikipedia...<https://en.wikipedia.org/wiki/Em_(typography)> "One em was traditionally defined as the width of the capital M in the current typeface and point size..." "In Cascading Style Sheets, the em unit is the height of the font in nominal points or inches." ...And finally there is one "rem" to save us all... "To make style rules that depend only on the default font size, another unit was developed: the rem. The rem, or root em, is the font size of the root element of the document. Unlike the em, which may be different for each element, the rem is constant throughout the document." More on rem's here<https://www.w3.org/Style/Examples/007/units.en.html#future> cheers, Ian.

“Smart Contracts” May Not Be So Smart
by Lawrence D'Oliveiro 23 Feb '17

23 Feb '17

To review, “smart contracts” are a feature of some blockchain-based systems, which allow an interaction between multiple parties to be encoded as a set of rules which will be executed automatically by the system, so that neither the parties nor anyone else can prevent those rules from being enforced. ... To give just one example, a legal contract need not try to anticipate absolutely every relevant event that might occur. If some weird thing happens that is not envisioned in a regular legal contract, the parties can work out a modification to the contract that seems reasonable to them, and failing that, a judge might decide the outcome, subject to established legal principles. Similarly, a single error or “bug” in writing a regular contract, causing its literal meaning to differ from what the parties intended, is unlikely to lead to extreme results because the legal system will often resolve such a problem by trying to be reasonable. Contrast this with “smart contracts” where a bug in a “contract’s” code can lead to a perverse result that may allow one party to exploit the bug, extracting much of the value out of the arrangement with no recourse for the other parties. That’s what happened with the DAO in Ethereum, leading to a controversial attempt to unwind a legal-according-to-the-rules set of transactions, and dividing the Ethereum community. <http://freedom-to-tinker.com/2017/02/20/smart-contracts-neither-smart-not-c…>

Catching Fishing Pirates With Signals Analysis
by Lawrence D'Oliveiro 22 Feb '17

22 Feb '17

Every vessel on the ocean broadcasts its identity and location using the automatic identification system (AIS), which is mostly used to prevent ships from colliding. These days it can also be used to track ship locations, as most AIS data is relayed through satellites. If you want to hide on the sea, the first thing you do is make your vessel "dark" by turning off your AIS broadcasts. What's interesting about pirate fishing vessels, however, is that they need to rendezvous with legitimate reefers if they want to get paid for their catch. To find the pirates, Amos told Ars, he and Bergman needed to look for odd patterns in the behavior of reefers. The group partnered with Global Fishing Watch to work on mapping satellite AIS data, and those patterns began to emerge. "Often with reefers they come to a halt in the middle of the ocean," Amos said. "We don’t see other broadcasting vessels, but we can be confident based on what that ship is doing that they must be rendezvousing with dark vessels." <https://arstechnica.com/tech-policy/2017/02/to-catch-a-thief-with-satellite…> I guess this counts as a “big data” application...

Especially as he says he ran a factory reset, reset his garage door and had traded the old car through a factory dealership ... which ... should have revoked his access to the old car. <https://www.theregister.co.uk/2017/02/20/connected_car_in_the_secondhand_lo…> Seems to me this could happen with other kinds of “smart” devices as well.

Linus Torvalds: Talk of Tech Innovation is Bullshit. Shut Up and Get the Work Done

Don't do this big 'think different'... screw that. It's meaningless. Ninety-nine per cent of it is get the work done." In a deferential interview at the Open Source Leadership Summit in California on Wednesday, conducted by Jim Zemlin, executive director of the Linux Foundation, Torvalds discussed how he has managed the development of the Linux kernel and his attitude toward work. "All that hype is not where the real work is," said Torvalds. "The real work is in the details."

Google's Not-so-secret New OS
by Peter Reutemann 16 Feb '17

16 Feb '17

'According to reports late last year, Google is working on a new operating system called Andromeda. Much about it is still unknown, but according to the documentations Google has provided on its website, it's clear that the Fuchsia is the actual name of the operating system, and the kernel is called Magenta. A tech enthusiast dug around the documentations to share the followings: To my naive eyes, rather than saying Chrome OS is being merged into Android, it looks more like Android and Chrome OS are both being merged into Fuchsia. It's worth noting that these operating systems had previously already begun to merge together to an extent, such as when the Android team worked with the Chrome OS team in order to bring Update Engine to Nougat, which introduced A/B updates to the platform. Google is unsurprisingly bringing up Andromeda on a number of platforms, including the humble Intel NUC. ARM, x86, and MIPS bring-up is exactly what you would expect for an Android successor, and it also seems clear that this platform will run on Intel laptops. My best guess is that Android as an API and runtime will live on as a legacy environment within Andromeda. That's not to say that all development of Android would immediately stop, which seems extremely unlikely. But Google can't push two UI APIs as equal app frameworks over the long term: Mojo is clearly the future. Ah, but what is Mojo? Well it's the new API for writing Andromeda apps, and it comes from Chromium. Mojo was originally created to "extract a common platform out of Chrome's renderer and plugin processes that can support multiple types of sandboxed content."' -- source: https://mobile.slashdot.org/story/17/02/15/1023242 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/

JavaScript Attack Breaks ASLR On 22 CPU Architectures
by Peter Reutemann 16 Feb '17

16 Feb '17

'Five researchers from the Vrije University in the Netherlands have put together an attack that can be carried out via JavaScript code and break ASLR protection on at least 22 microprocessor architectures from vendors such as Intel, AMD, ARM, Allwinner, Nvidia, and others. The attack, christened ASLRCache, or AnC, focuses on the memory management unit (MMU), a lesser known component of many CPU architectures, which is tasked with improving performance for cache management operations. What researchers discovered was that this component shares some of its cache with untrusted applications, including browsers. This meant that researchers could send malicious JavaScript that specifically targeted this shared memory space and attempted to read its content. In layman's terms, this means an AnC attack can break ASLR and allow the attacker to read portions of the computer's memory, which he could then use to launch more complex exploits and escalate access to the entire OS. Researchers have published two papers [1, 2] detailing the AnC attack, along with two videos[1, 2] showing the attack in action.' -- source: https://developers.slashdot.org/story/17/02/15/2149235 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/

Web Copy-Protection As A Censorship Tool
by Lawrence D'Oliveiro 13 Feb '17

13 Feb '17

There has been ongoing work at the W3C for some time to standardize “Encrypted Media Extensions” (EME), with the usual claims that many publishers will refuse to offer their content without this kind of “protection”. The mitigating argument has been made that such a “feature” would be optional--the browser user could always turn it off. Well, it turns out Google has removed the option to disable its implementation of EME from Chrome. A further worry is that many countries’ copyright laws include provisions that prohibit the circumvention of copy-protection mechanisms. So work by security researchers to audit browsers that implement EME could be interpreted as violations of such provisions. Many have requested that the W3C explicitly state that EME conformance cannot be (ab)used in such a way, but so far it has refused. <https://www.techdirt.com/articles/20170201/14285436609/codification-web-drm…>

'"The prestigious FOSS project replacing the entire city's administration IT with FOSS based systems, is about to be cancelled and decommissioned," writes long-time Slashdot reader Qbertino. TechRepublic reports: Politicians at open-source champion Munich will next week vote on whether to abandon Linux and return to Windows by 2021. The city authority, which made headlines for ditching Windows, will discuss proposals to replace the Linux-based OS used across the council with a Windows 10-based client. If the city leaders back the proposition it would be a notable U-turn by the council, which spent years migrating about 15,000 staff from Windows to LiMux, a custom version of the Ubuntu desktop OS, and only completed the move in 2013... The use of the open-source Thunderbird email client and LibreOffice suite across the council would also be phased out, in favor of using "market standard products" that offer the "highest possible compatibility" with external and internal software... The full council will vote on whether to back the plan next Wednesday. If all SPD and CSU councillors back the proposal put forward by their party officials, then this new proposal will pass, because the two parties hold the majority. The leader of the Munich Green Party says the city will lose "many millions of euros" if the change is implemented. The article also reports that Microsoft moved its German headquarters to Munich last year.' -- source: https://yro.slashdot.org/story/17/02/11/1930217 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/

Bored with ho-hum cloud backups? Use Usenet (yes, Usenet!) instead
by Peter Reutemann 11 Feb '17

11 Feb '17

'Cloud backups these days are all the rage—for good reason. Rather than dealing with shuffling physical media offsite, you can simply back up the data offsite, where it can be stored in one of many professionally monitored data centers. Unfortunately, this kind of service isn’t free, and the cost can be a barrier. However, there is a cost-effective way to store your cloud backups: Usenet. With access to a Usenet news server, you can simply upload your backup there, and it will be stored redundantly in news servers all over the world. Best of all, this approach typically costs considerably less than a cloud backup service.' -- source: https://arstechnica.com/information-technology/2017/02/bored-with-ho-hum-cl… 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/

Oracle refuses to accept pro-Google “fair use” verdict in API battle
by Peter Reutemann 11 Feb '17

11 Feb '17

'Google successfully made its case to a jury last year that its use of Java APIs in Android was "fair use." A San Francisco federal jury rejected Oracle's claim that the mobile system infringed Oracle's copyrights. But Oracle isn't backing down. Late Friday, the company appealed the high-profile verdict to a federal appeals court. This is the latest stage of a seemingly never-ending legal battle over intellectual property that began in 2010. The conflict has meandered through two federal trials, in addition to multiple trips to the appellate courts and to the Supreme Court. Oracle opened its brief to the US Court of Appeals for the Federal Circuit right where it left off after losing its case. Among other things, Oracle is refusing to believe that the "fair use" defense to copyright-infringement allegations should have protected Google from having to pay billions of dollars in damages.' -- source: https://arstechnica.com/tech-policy/2017/02/oracle-refuses-to-accept-pro-go… 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/

When A Safety Check Becomes A Point Of Failure...
by Lawrence D'Oliveiro 10 Feb '17

10 Feb '17

All inbound networking for GCE instances, load balancers and VPN tunnels enter via shared layer 2 load balancers. These load balancers are configured with changes to IP addresses for these resources, then automatically tested in a canary deployment, before changes are globally propagated. The issue was triggered by a large set of updates which were applied to a rarely used load balancing configuration. The application of updates to this configuration exposed an inefficient code path which resulted in the canary timing out. From this point all changes of public addressing were queued behind these changes that could not proceed past the testing phase. In other words, the safety system for validating configuration updates before allowing deployment suffered a failure which blocked all configuration updates thereafter. I guess the answer is to add a watchdog for the canaries ... how many more metaphors can I mix in? <http://www.theregister.co.uk/2017/02/10/google_cloud_outage_explanation/>

We Finally Have A Computer That Can Survive The Surface Of Venus
by Lawrence D'Oliveiro 10 Feb '17

The Venera landers that the USSR sent to Venus in the 1970s and 1980s were able to survive for up to 2 hours by heavy use of refrigeration and pre-cooling. But now researchers are testing electronics based on silicon carbide, which can work without special protection at very high voltages and temperatures: The chip, a simple 3-stage oscillator, kept functioning [in Venus-like conditions] at a steady 1.26MHz for 521 hours (21.7) days before the [test rig] had to be shut down. <https://arstechnica.co.uk/gadgets/2017/02/venus-computer-chip/>.

Met Goes Public Domain
by Lawrence D'Oliveiro 10 Feb '17

New York’s Metropolitan Museum of Art is putting 375,000 digitized images online under a Creative Commons CC0 (effectively Public Domain) licence. As Techdirt notes <https://www.techdirt.com/articles/20170208/13005636669/met-goes-public-doma…>, it shouldn’t have to bother specifying such a licence: we should be able to take for granted that digitizations of public-domain works should themselves be public-domain. Unfortunately, others with control over such works (and sizeable legal budgets) think differently. So all kudos to the Met for making this very clear.

“[A] website in Romania ... obtained and posted Canadian judicial and tribunal decisions. These were all public documents, but they were not previously indexed by Google, which meant their contents were effectively hidden. The Romanian site allowed its copies to be indexed by Google, which made the decisions and the Canadian citizens involved visible for the first time -- something the people affected were not happy about. They complained to the Privacy Commissioner of Canada, who ruled that the Romanian site violated Canadian privacy law.” <https://www.techdirt.com/articles/20170208/02314536660/landmark-court-decis…>

Microsoft hosts the Windows source in a monstrous 300GB Git repository
by Peter Reutemann 07 Feb '17

07 Feb '17

'Microsoft has been working to enhance Git to improve the way it handles vast repositories. Central to this effort is a new project released (in part) as open source Git Virtual File system (GVFS). The premise of GVFS is straightforward enough: rather than fetching all the data at once, only a bare skeleton of the repository needs to be populated up front. The virtualized file system subsequently retrieves additional data on a demand-driven, as-needed basis. Building one particular Windows component, for example, will cause GVFS to fetch the files that make up that component, along with anything that the component depends on, but it will stop short of fetching all the many hundreds of gigabytes the repository contains.' -- source: https://arstechnica.com/information-technology/2017/02/microsoft-hosts-the-… I remember using SourceSafe way back.

Chrome 56 Quietly Added Bluetooth Snitch API
by Peter Reutemann 06 Feb '17

06 Feb '17

'When Google popped out Chrome 56 at the end of January it was keen to remind us it's making the web safer by flagging non-HTTPS sites. But Google made little effort to publicise another feature that's decidedly less friendly to privacy, because it lets websites ask about users' Bluetooth devices and harvest information from them through the browser. That's more a pitch to developers, as is clear in this YouTube video from Pete LePage of the Chrome Developers team. "Until now, the ability to communicate with Bluetooth devices has been possible only for native apps. With Chrome 56, your Web app can communicate with nearby Bluetooth devices in a private and secure manner, using the Web Bluetooth API," Google shares in the video. "The Web Bluetooth API uses the GATT [Generic Attribute Profile - ed] protocol, which enables your app to connect to devices such as light bulbs, toys, heart-rate monitors, LED displays and more, with just a few lines of JavaScript." In other words, the API lets websites ask your browser "what Bluetooth devices can you see," find out what your fridge, and so on, is capable of, and interact with it.' -- source: https://yro.slashdot.org/story/17/02/06/1425208 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/

Thought there already was a 100-gigabit-per-second Ethernet spec. But it seems that still isn’t quite practical enough (cost? range?) for common use. Nor is the 40-gigabit-per-second fallback.

Windows DRM-Protected Files Used To Decloak Tor Browser Users
by Peter Reutemann 03 Feb '17

03 Feb '17

'Downloading and trying to open Windows DRM-protected multimedia files can deanonymize Tor Browser users and reveal their real IP addresses, security researchers from Hacker House have warned. On Windows, multimedia files encoded with special Microsoft SDK will automatically open an IE window and access a URL to check the file's license. Since this request is sent outside of the Tor Browser and without user interaction, this can be used to ping law enforcement servers and detect the user's real IP address and other details. For example, law enforcement could host properly signed DRM-protected files on sites pretending to host child pornography. When a user would try to view the file, the DRM multimedia file would use Internet Explorer to ping a server belonging to the law enforcement agency. The same tactic can also be used to target ISIS militants trying to view propaganda videos, illegal drug and weapons buyers trying to view video product demos, political dissidents viewing news videos, and more. A video of the attack is available here.' -- source: https://yro.slashdot.org/story/17/02/02/231229 Not sure whether that applies to Linux/Wine/IE as well.

How Google fought back against a crippling IoT-powered botnet and won
by Peter Reutemann 02 Feb '17

02 Feb '17

'In September, KrebsOnSecurity—arguably the Internet's most intrepid source of security news—was on the receiving end of some of the biggest distributed denial-of-service attacks ever recorded. The site soon went dark after Akamai said it would no longer provide the site with free protection, and no other DDoS mitigation services came forward to volunteer their services. A Google-operated service called Project Shield ultimately brought KrebsOnSecurity back online and has been protecting the site ever since. At the Enigma security conference on Wednesday, a Google security engineer described some of the behind-the-scenes events that occurred shortly after Krebs asked the service for help, and in the months since, they said yes. While there was never significant hesitancy to bring him in, the engineers did what engineers always do—weighed the risks against the benefits. "What happens if this botnet actually takes down google.com and we lose all of our revenue?" Google Security Reliability Engineer Damian Menscher recalls people asking. "But we considered [that] if the botnet can take us down, we're probably already at risk anyway. There's nothing stopping them from attacking us at any time. So we really had nothing to lose here."' -- source: https://arstechnica.com/security/2017/02/how-google-fought-back-against-a-c… 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/

Not sure how many you get for that USD9,575 base price... Seems like there is no really competitive market for GPGPU hardware--it is totally dominated by NVidia, and nobody else gets a serious look-in. So the industry-standard OpenCL API languishes, since the dominant player prefers its own proprietary alternative, and there is little pressure from users to be able to port their code to competing products.

Google AI on raspberry pi
by rowan schischka 31 Jan '17

"Google has developed a huge range of tools for machine learning, IoT, wearables, robotics, and home automation, and it wants Raspberry Pi fans to fill out a survey <https://google.qualtrics.com/jfe/form/SV_3yMNYryaP4WsCwJ?Source=RaspPi> that will help it to understand what tools to provide." http://www.zdnet.com/article/google-is-bringing-ai-to-your-raspberry-pi/ I just took the survey and I don't get any impression of what tools they will bring to the r-pi. It was pretty simple, no email address required to participate. The questions were how old are you, what area are your projects in, and how frequently do you work on your projects. Im sure with the processing power of r-pi we'll see some sort of web API which wouldn't really need to be specific to the r-pi. It will be interesting to watch what they come up with so if you have maker projects, take the survey. -- Rowan Schischka

Code-Signing Vs Software Developers
by Lawrence D'Oliveiro 26 Jan '17

26 Jan '17

This item <http://www.theregister.co.uk/2017/01/26/windows_code_signing_changes/> is about Microsoft adopting some recommendations from the “Certificate Authority Security Council” that code-signing keys should be embedded in special hardware devices, not simply kept as files on a regular computer. Apparently they are also suggesting some yet-to-be-defined “cloud-based service” as an alternative, which raises some questions. One of the commenters linked this article <http://www.pcworld.com/article/2846653/storage-for-spies-how-the-fips-stand…> which gives a good overview of hardware signing key devices that are certified to the various levels of the FIPS 140-2 standard. The idea is not a new one. But like most security techniques that are worth a darn, it can cause all kinds of irritations in practical use.

Happy new year everybody. Somehow i missed the first meeting. For the next one could we do a live benchmark of web browsers available on linux? Theres a couple of things to consider such as: how quickly new browser versions are available - security updates accuracy of rendering - i have found Midori feels fast but does not display some web pages the same as others Theres also flash and HTML5 we could look into. A few years ago (around 2010/2011) I made a simple HTML5 canvas with some animations that looked like a space invaders game, from memory, on debian i had the following results: IE, can't remember version, got around 20 fps chrome scored 120 something fps firefox received around 12 fps I dont know what benchmarks are available for us to use but it would be interesting, it would also be interesting to look at comparing browsers on fedora and ubuntu -- Kind Regards Rowan Schischka

Mossberg: What’s up with Firefox, the browser that time forgot?
by Peter Reutemann 25 Jan '17

'Until about five years ago, techies and others who wanted a speedier, extensible, more privacy-oriented web browser on their desktops often immediately downloaded Mozilla's Firefox to use instead of Internet Explorer on Windows or Safari on the Mac. But those days seem long ago. Firefox is hardly discussed today, and its usage has cratered from a high of over 30 percent of the desktop browser market in 2010 to about 12 percent today, according to Mozilla, citing stats from NetMarketShare. (Various other analytics firms put the share as low as 10 percent or as high as 15 percent.) And Firefox’s share on mobile devices is even worse, at under 1 percent, according to the same firm. Today, the go-to-browser is Google’s Chrome, which has over a 50 percent share on both desktop and mobile, according to NetMarketShare.' -- source: http://www.theverge.com/2017/1/25/14376710/walt-mossberg-mozilla-firefox-br… 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/
