KDE on Chakra and on Phones

KDE

  • Chakra GNU/Linux Users Get KDE Plasma 5.15 Desktop and KDE Applications 18.12.2

    Users of the Chakra GNU/Linux distribution have received yet another batch of updates that bring them all the latest KDE technologies and security fixes.

    Less than a week after the previous update, which brought the KDE Plasma 5.14.5, KDE Frameworks 5.54.0, and KDE Applications 18.2.1 releases, Chakra GNU/Linux users can now install the recently released KDE Plasma 5.15 desktop environment, along with the KDE Frameworks 5.55.0 and KDE Applications 18.12.2 open-source software suites.

  • A mobile Plasma Sprint

    I was last week in Berlin at the Plasma Mobile sprint, graciously hosted by Endocode, almost exactly 9 years after the first Plasma Mobile sprint in which we first started to explore Plasma and other software by KDE on mobile phones, which at the time were just starting to become powerful enough to run a full Linux stack (Hi N900!)

    Now the project got a wide breath of fresh air: the thing that impressed me the most was how many new faces came at the sprint and are now part of the project.

    [...]

    As for Plasma Mobile software in itself, we did many bugfixes on the main shell/homescreen to have a better first impact, and a significant improvement came in KWin about high DPI scaling when running on an Halium system.

    Also, many improvoements were done in the Kirigami framework, which is the main toolkit recommended to be used to build applications for Plasma Mobile: as developers of several applications that use Kirigami were present there, we could do very fast feedback and debug sessions.

Governments Are Spending Billions on Software They Can Get with Freedom

Filed under
OSS

In the proprietary software world, when software is released, and when users buy that software, they don’t usually buy the entire software, but instead, they buy what’s known as an end-user license agreement (EULA). This EULA gives them the right to do only some specific things with that software. Usually, users are not allowed to copy, redistribute, share or modify the software, which is the main difference between proprietary software and free software (as in freedom).

It’s extremely annoying and sad that in the 21st century, governments all around the world are still paying millions of dollars for software each year; It’s more sad, because they are not paying for software, they are paying for a license to use a software in a specific way on yearly basis. Now say you were a country with millions of machines, can you just imagine the amounts of money that we are spending worldwide just to get those computers working?

More importantly, you don’t get the software. You just get a usage license that you must renew after a year. While free software gives you the 4 basic freedoms: The ability to read, modify, redistribute and use the software in any way you want.

Choosing to run a proprietary software over free software-where alternatives do exist-is an extremely wrong decision that governments are doing worldwide. And by choosing proprietary software over free software, we are losing huge amounts of money that instead could’ve been spent on health, education, public infrastructure or anything else in the country.

More importantly, the money that’s going to to pay for this software and its support could’ve been invested in developing alternative free solutions their selves; How about instead of spending $50M per year on the EULAs of Microsoft Office because “LibreOffice is not good”, that you just try to invest $25M in LibreOffice itself for one time only and see what happens? As a country, your technical infrastructure will develop if you turn it not just to a user of free software, but a producer as well. And only free software would allow you to do that.

During the period of our investigation, we checked the financial reports of many governments worldwide and their spending on IT. The amounts of money that governments are paying per year for proprietary software is very huge. And most of it isn’t actually for the licenses of using that software, but for the support.

It’s an issue, because it’s not going to end. Governments are claiming problems and issues in transferring to free software, and in doing that, they keep paying millions and millions of dollars each year, and continue to do so indefinitely; They have no plans to switch to free (as in freedom) locally-developed alternatives.

Let’s see some examples of how governments worldwide are spending their money on software.

Security: Updates, Thread Safety and Crypto Policies in Red Hat Enterprise Linux 8

Filed under
Security
  • Security updates for Thursday
  • Hacks.Mozilla.Org: Fearless Security: Thread Safety

    While this allows programs to do more faster, it comes with a set of synchronization problems, namely deadlocks and data races. From a security standpoint, why do we care about thread safety? Memory safety bugs and thread safety bugs have the same core problem: invalid resource use. Concurrency attacks can lead to similar consequences as memory attacks, including privilege escalation, arbitrary code execution (ACE), and bypassing security checks.

    Concurrency bugs, like implementation bugs, are closely related to program correctness. While memory vulnerabilities are nearly always dangerous, implementation/logic bugs don’t always indicate a security concern, unless they occur in the part of the code that deals with ensuring security contracts are upheld (e.g. allowing a security check bypass). However, while security problems stemming from logic errors often occur near the error in sequential code, concurrency bugs often happen in different functions from their corresponding vulnerability, making them difficult to trace and resolve. Another complication is the overlap between mishandling memory and concurrency flaws, which we see in data races.

    Programming languages have evolved different concurrency strategies to help developers manage both the performance and security challenges of multi-threaded applications.

  • Consistent security by crypto policies in Red Hat Enterprise Linux 8

    Software development teams, whether open or closed source, are often composed of many groups that own individual components. Database applications typically come from a different team than ones developed by HTTP or SSH services, and others. Each group chooses libraries, languages, utilities, and cryptographic providers for their solution. Having specialized teams contributing to an application may improve the final product, but it often makes it challenging to enforce a consistent cryptographic policy on a system.

Android Things is now only for smart speakers and displays

Android

Android Things will now focus solely on OEM-built smart speakers and displays. Google is discontinuing public access to i.MX8M, Snapdragon, and MediaTek based production modules for the OS.

Google announced it is scaling back Android Things as a general-purpose IoT platform. The Arm-based production boards from Innocomm, Intrinsyc, and MediaTek that that Google was reselling to vendors with pre-loaded Android Things will no longer be publicly supported. Instead: “Given the successes we have seen with our partners in smart speakers and smart displays, we are refocusing Android Things as a platform for OEM partners to build devices in those categories moving forward,” wrote Dave Smith, Google’s Developer Advocate for IoT.

  • Snapd flaw gives attackers root access on Linux systems
  • Dimitri John Ledkov: Encrypt all the things

    Went into blogger settings and enabled TLS on my custom domain blogger blog. So it is now finally a https://blog.surgut.co.uk However, I do use feedburner and syndicate that to the planet. I am not sure if that is end-to-end TLS connections, thus I will look into removing feedburner between my blog and the ubuntu/debian planets. My experience with changing feeds in the planets is that I end up spamming everyone. I wonder, if I should make a new tag and add that one, and add both feeds to the planet config to avoid spamming old posts.

    Next up went into gandi LiveDNS platform and enabled DNSSEC on my domain. It propagated quite quickly, but I believe my domain is now correctly signed with DNSSEC stuff. Next up I guess, is to fix DNSSEC with captive portals. I guess what we really want to have on "wifi" like devices, is to first connect to wifi and not set it as default route. Perform captive portal check, potentially with a reduced DNS server capabilities (ie. no EDNS, no DNSSEC, etc) and only route traffic to the captive portal to authenticate. Once past the captive portal, test and upgrade connectivity to have DNSSEC on. In the cloud, and on the wired connections, I'd expect that DNSSEC should just work, and if it does we should be enforcing DNSSEC validation by default.

    So I'll start enforcing DNSSEC on my laptop I think, and will start reporting issues to all of the UK banks if they dare not to have DNSSEC. If I managed to do it, on my own domain, so should they!

  • Google Chrome is getting virtual desktops (probably)

    If you’re the sort of person who regularly runs a bunch of programs on your computer at once, you may already be a fan of using multiple monitors. You can put one set of apps on one screen and a different set on another and tilt your head a bit to switch your focus from one to the other.

    But if you have a laptop, you’re probably confined to using a single screen from time to time (unless you have a portable monitor that you take everywhere you go).

    Enter virtual desktops. Most modern operating systems offer a way to create multiple virtual workspaces that you can flip between. It’s not quite as seamless as using multiple displays, but it’s certainly more compact (and more energy efficient, for that matter).

  • The long, slow death of commercial Unix [Ed: Microsoft propagandist Andy Patrizio should also do an article about the death of Windows Server.]

    In the 1990s and well into the 2000s, if you had mission-critical applications that required zero downtime, resiliency, failover and high performance, but didn’t want a mainframe, Unix was your go-to solution.

    If your database, ERP, HR, payroll, accounting, and other line-of-business apps weren’t run on a mainframe, chances are they ran on Unix systems from four dominant vendors: Sun Microsystems, HP, IBM and SGI. Each had its own flavor of Unix and its own custom RISC processor. Servers running an x86 chip were at best used for file and print or maybe low-end departmental servers.

Linux Kernel: Rusty Russell and More

Filed under
Linux
  • Rusty's reminiscences

    Rusty Russell was one of the first developers paid to work on the Linux kernel and the founder of the conference now known as linux.conf.au (LCA); he is one of the most highly respected figures in the Australian free-software community. The 2019 LCA was the 20th edition of this long-lived event; the organizers felt that it was an appropriate time to invite Russell to deliver the closing keynote talk. He used the opportunity to review his path into free software and the creation of LCA, but first a change of clothing was required.

    [...]

    He found his way into the Unix world in 1992, working on an X terminal connected to a SunOS server. SunOS was becoming the dominant Unix variant at that time, and there were a number of "legendary hackers" working at Sun to make that happen. But then Russell discovered another, different operating system: Emacs. This system was unique in that it was packaged with a manifesto describing a different way to create software. The idea of writing an entire operating system and giving it away for free seemed fantastical at the time, but the existence of Emacs meant that it couldn't be dismissed.

    Even so, he took the normal path for a few more years, working on other, proprietary Unix systems; toward the end he ended up leading a research project developed in C++. The proprietary compilers were too expensive, so he was naturally using GCC instead. He did some digging in preparation for this talk and found his first free-software contribution, which was a patch to GCC in 1995. The experience of collaborating to build better software for everybody was exhilarating, but even with as much fun as he was having there was another level to aim for.

  • Fixing page-cache side channels, second attempt

    The kernel's page cache, which holds copies of data stored in filesystems, is crucial to the performance of the system as a whole. But, as has recently been demonstrated, it can also be exploited to learn about what other users in the system are doing and extract information that should be kept secret. In January, the behavior of the mincore() system call was changed in an attempt to close this vulnerability, but that solution was shown to break existing applications while not fully solving the problem. A better solution will have to wait for the 5.1 development cycle, but the shape of the proposed changes has started to come into focus.
    The mincore() change for 5.0 caused this system call to report only the pages that are mapped into the calling process's address space rather than all pages currently resident in the page cache. That change does indeed take away the ability for an attacker to nondestructively test whether specific pages are present in the cache (using mincore() at least), but it also turned out to break some user-space applications that legitimately needed to know about all of the resident pages. The kernel community is unwilling to accept such regressions unless there is absolutely no other solution, so this change could not remain; it was thus duly reverted for 5.0-rc4.

    Regressions are against the community's policy, but so is allowing known security holes to remain open. A replacement for the mincore() change is thus needed; it can probably be found in this patch set posted by Vlastimil Babka at the end of January. It applies a new test to determine whether mincore() will report on the presence of pages in the page cache; in particular, it will only provide that information for memory regions that (1) are anonymous memory, or (2) are backed by a file that the calling process would be allowed to open for write access. In the first case, anonymous mappings should not be shared across security boundaries, so there should be no need to protect information about page-cache residency. For the second case, the ability to write a given file would give an attacker the ability to create all kinds of mischief, of which learning about which pages are cached is relatively minor.

  • Linux Kernel Getting io_uring To Deliver Fast & Efficient I/O

    The Linux kernel is getting a new ring for Valentine's Day... io_uring. The purpose of io_uring is to deliver faster and more efficient I/O operations on Linux and should be coming with the next kernel cycle. 

    Linux block maintainer and developer behind io_uring, Jens Axboe of Facebook, queued the new interface overnight into the linux-block/for-next on Git. The io_uring interface provides submission and completion queue rings that are shared between the application and kernel to avoid excess copies. The new interface has just two new system calls (io_uring_setup and io_uring_enter) for dealing with I/O. Axboe previously worked on this code under the "aioring" name.

KDE neon Systems Based on Ubuntu 16.04 LTS Have Reached End of Life, Upgrade Now

With the rebase of KDE neon on Ubuntu 18.04 LTS (Bionic Beaver) on September 2018, the development team have decided it's time to put the old series based on Ubuntu 16.04 LTS (Xenial Xerus) to rest once and for all as most users already managed to upgrade their systems to the new KDE neon series based on Canonical's latest Ubuntu LTS release.

"KDE neon was rebased onto Ubuntu bionic/18.04 last year and upgrades have gone generally smooth. We have removed xenial/16.04 build from our machines (they only hang around for as long as they did because it took a while to move the Snap builds away from them) and the apt repo will remove soon," said the devs.

  • Saving birds with technology

    Two members of the Cacophony Project came to linux.conf.au 2019 to give an overview of what the project is doing to increase the amount of bird life in New Zealand. The idea is to use computer vision and machine learning to identify and eventually eliminate predators in order to help bird populations; one measure of success will be the volume and variety of bird song throughout the islands. The endemic avian species in New Zealand evolved without the presence of predatory mammals, so many of them have been decimated by the predation of birds and their eggs. The Cacophony Project is looking at ways to reverse that.

  • Mozilla's initiatives for non-creepy deep learning

    Jack Moffitt started off his 2019 linux.conf.au talk by calling attention to Facebook's "Portal" device. It is, he said, a cool product, but raises an important question: why would anybody in their right mind put a surveillance device made by Facebook in their kitchen? There are a lot of devices out there — including the Portal — using deep-learning techniques; they offer useful functionality, but also bring a lot of problems. We as a community need to figure out a way to solve those problems; he was there to highlight a set of Mozilla projects working toward that goal.
    He defined machine learning as the process of making decisions and/or predictions by modeling from input data. Systems using these techniques can perform all kinds of tasks, including language detection and (bad) poetry generation. The classic machine-learning task is spam filtering, based on the idea that certain words tend to appear more often in spam and can be used to detect unwanted email. With more modern neural networks, though, there is no need to do that sort of feature engineering; the net itself can figure out what the interesting features are. It is, he said, "pretty magical".

  • Lisp and the foundations of computing

    At the start of his linux.conf.au 2019 talk, Kristoffer Grönlund said that he would be taking attendees back 60 years or more. That is not quite to the dawn of computing history, but it is close—farther back than most of us were alive to remember. He encountered John McCarthy's famous Lisp paper [PDF] via Papers We Love and it led him to dig deeply into the Lisp world; he brought back a report for the LCA crowd.

    Grönlund noted that this was his third LCA visit over the years. He was pleased that his 2017 LCA talk "Package managers all the way down" was written up in LWN. He also gave his "Everyone gets a pony!" talk at LCA 2018. He works for SUSE, which he thanked for sending him to the conference, but the company is not responsible for anything in the talk, he said with a grin.

But now nearly two decades after JPEG2000 was published, it's at least supported by WebKitGTK.

The Mozilla Thunderbird 60.5.0 package gave more search engine options in certain locations offering Google and DuckDuckGo available by default. The email client also added Thunderbird FileLink with WeTransfer to upload large attachments. Thunderbird Filelink provides support for online storage services and allows upload attachments to an online storage service and then replaces the attachment in the message with a link. General-purpose parser generator bison 3.3.1 removed support for the 32-bit C/C++ development system DJGPP. The compiler cache, ccache 3.6, which speeds up recompilation by caching previous compilations, fixed a problem due to Clang, which is a C language family frontend for LLVM, overwriting the output file when compiling an assembler file and added support for GNU Compiler Collection‘s `-ffile-prefix-map` option. The 1.12.12 version update for dbus stopped a few memory leaks and added a couple patches. The epson-inkjet-printer-escpr 1.6.35 version added support for new printer models EcoTank ET-M1100 and Epson WorkForce ST-2000. GNU C Library glibc 2.29 added getcpu wrapper function, which returns the currently used CPU and NUMA node, and optimized the generic exp, exp2, log, log2, pow, sinf, cosf, sincosf and tanf functions. Cross-platform widget toolkit gtk3 3.24.5 implement gdk_window_present for Wayland, updated translations and refreshed the theme. The health-checker 1.1 package added new plugins for cri-o and kubelet. Users of the professional-quality vector-graphics application Inkscape can now use the 0.92.4 version; the new version improves preferences of the measuring tool when grids are visible and fixes a crash that would happen when a user does a Shift/Ctrl-click when handling shapes. Tumbleweed users will have 1.7x faster performance with Ruby 2.6 as the default as compared to Ruby 2.5. Other library packages updated in the snapshot were libosinfo 1.3.0, libsodium 1.0.17, libsolv 0.7.3, libstorage-ng 4.1.86 and libzypp 17.11.1.

  • No Surprise But Intel Linux Developers Are Working Towards Adaptive-Sync Support

    Back during the Intel Architecture Day event in December, Intel confirmed that finally with Icelake "Gen 11" graphics there is Adaptive-Sync support after talking about it for several years. While they didn't explicitly mention Linux support, they've been largely spot on for years with supporting new display features on Linux and this should be the case as well with Adaptive-Sync and their next-generation graphics.

  • Mesa 19.0-RC4 Released With More Fixes

    After yesterday's botched Mesa 19.0-RC3 release, Mesa 19.0-RC4 is now available while it's looking like two weeks or so until the stable debut.

    Due to the prior release candidates missing out on many fixes due to a scripting failure, Mesa 19.0-RC4 is out today with the corrected script that's pulled in a great deal of fixes onto the 19.0 branch. Over the earlier release candidates, Mesa 19.0-RC4 adds in a surprisingly large number of Nouveau NV50/NVC0 fixes, several RADV Radeon Vulkan driver fixes, and a random assortment of other fixes as seen in the 19.0 branch.

Opening Files with Qt on Android

After addressing Android support in KF5Notifications another fairly generic task that so far required Android specific code is next: opening files. Due to the security isolation of apps and the way the native “file dialog” works on Android this is quite different from other platforms, which makes application code a bit ugly. This can be fixed in Qt though. Read more

Ubuntu-Centric Full Circle Magazine and Debian on the Raspberryscape

  • Full Circle Magazine: Full Circle Weekly News #121
  • Debian on the Raspberryscape: Great news!
    I already mentioned here having adopted and updated the Raspberry Pi 3 Debian Buster Unofficial Preview image generation project. As you might know, the hardware differences between the three families are quite deep ? The original Raspberry Pi (models A and B), as well as the Zero and Zero W, are ARMv6 (which, in Debian-speak, belong to the armel architecture, a.k.a. EABI / Embedded ABI). Raspberry Pi 2 is an ARMv7 (so, we call it armhf or ARM hard-float, as it does support floating point instructions). Finally, the Raspberry Pi 3 is an ARMv8-A (in Debian it corresponds to the ARM64 architecture). [...] As for the little guy, the Zero that sits atop them, I only have to upload a new version of raspberry3-firmware built also for armel. I will add to it the needed devicetree files. I have to check with the release-team members if it would be possible to rename the package to simply raspberry-firmware (as it's no longer v3-specific). Why is this relevant? Well, the Raspberry Pi is by far the most popular ARM machine ever. It is a board people love playing with. It is the base for many, many, many projects. And now, finally, it can run with straight Debian! And, of course, if you don't trust me providing clean images, you can prepare them by yourself, trusting the same distribution you have come to trust and love over the years.

OSS: SVT-AV1, LibreOffice, FSF and Software Freedom Conservancy

  • SVT-AV1 Already Seeing Nice Performance Improvements Since Open-Sourcing
    It was just a few weeks ago that Intel open-sourced the SVT-AV1 project as a CPU-based AV1 video encoder. In the short time since publishing it, there's already been some significant performance improvements.  Since the start of the month, SVT-AV1 has added multi-threaded CDEF search, more AVX optimizations, and other improvements to this fast evolving AV1 encoder. With having updated the test profile against the latest state as of today, here's a quick look at the performance of this Intel open-source AV1 video encoder.

  • What I learned during my internship with the FSF tech team
    Hello everyone, I am Hrishikesh, and this is my follow-up blog post concluding my experiences and the work I did during my 3.5 month remote internship with the FSF. During my internship, I worked with the tech team to research and propose replacements for their network monitoring infrastructure. A few things did not go quite as planned, but a lot of good things that I did not plan happened along the way. For example, I planned to work on GNU LibreJS, but never could find enough time for it. On the other hand, I gained a lot of system administration experience by reading IRC conversations, and by working on my project. I even got to have a brief conversation with RMS! My mentors, Ian, Andrew, and Ruben, were extremely helpful and understanding throughout my internship. As someone who previously had not worked with a team, I learned a lot about teamwork. Aside from IRC, we interacted weekly in a conference call via phone, and used the FSF's Etherpad instance for live collaborative editing, to take notes. The first two months were mostly spent studying the FSF's existing Nagios- and Munin-based monitoring and alert system, to understand how it works. The tech team provided two VMs for experimenting with Prometheus and Nagios, which I used throughout the internship. During this time, I also spent a lot of time reading about licenses, and other posts about free software published by the FSF.
