  • Microsoft quietly cuts off Win7 support for older Intel computers

    If you have a Pentium III, for example, you may no longer be able to install Win7 Monthly Rollups or Security-only patches, in spite of Microsoft's promise to support you until January 2020. It’s all about SSE2 and some retroactively fudged documentation. Will anybody notice?

  • Tracy Rosenberg on ICE’s Corporate Collaborators, Patty Lovera on the Undercovered Farm Bill

    This week on CounterSpin: “As a company, Microsoft is dismayed by the forcible separation of children from their families at the border,” the global tech company declared in a statement. “Family unification has been a fundamental tenet of American policy and law since the end of World War II.” The same Microsoft bragged a few months ago about ICE’s use of its Azure cloud computing services to “accelerate facial recognition and identification” of immigrants, though the post has since been altered to omit the phrase “we’re proud to support this work with our mission-critical cloud.”

  • SUSE Linux Enterprise 15 Announced As a Modular Operating System for Businesses

    SUSE announced the release of the long-anticipated SUSE Linux Enterprise 15 operating system for businesses and organizations of all sizes, bringing new features, updated components, and state-of-the-art GNU/Linux technologies.

  • Fedora To Deprecate YUM in Fedora 29 Release

    Many Linux users familiar with Fedora, CentOS, and Red Hat Enterprise Linux are familiar with YUM, but are oblivious to its origins in the much lesser known Yellowdog Linux, a now discontinued PowerPC variant of CentOS. And now, it seems, YUM is heading in the same direction.

  • Fourth GSoC Report

    As announced in the last report, i started looking into SSO solutions and evaluated and tested them. At the begining my focus was on SAML integration, but i soon realized that OAuth2 would be more important.

    I started with installing Lemonldap-NG. LL-NG is a WebSSO solution writting in perl that uses ModPerl or FastCGI for delivering Webcontent. There is a Debian package in stable, so the installation was no problem at all. The configuration was a bit harder, as LL-NG has a complex architecture with different vhosts. But after some fiddling i managed to connect the installation to our test LDAP instance and was able to authenticate against the LL-NG portal. Then i started to research how to integrate an OAuth2 client. For the tests i had on the one hand a gitlab installation that i tried to connect to the OAuth2 providers using the omniauth-oauth2-generic strategy. To have a bit more fine grained control over the OAuth2 client configuration i also used the python requests-oauthlib module and modified the web app example from their documentation to my needs. After some fiddling and a bit of back and forth on the lemonldap-ng mailinglist i managed both test clients to authenticate against LL-NG.

  • Automation & Risk

    Linaro created the LAVA (Linaro Automated Validation Architecture) project in 2010 to automate testing of software using real hardware. Over the seven years of automation in Linaro so far, LAVA has also spread into other labs across the world. Millions of test jobs have been run, across over one hundred different types of devices, ARM, x86 and emulated. Varied primary boot methods have been used alone or in combination, including U-Boot, UEFI, Fastboot, IoT, PXE. The Linaro lab itself has supported over 150 devices, covering more than 40 different device types. Major developments within LAVA include MultiNode and VLAN support. As a result of this data, the LAVA team have identified a series of automated testing failures which can be traced to decisions made during hardware design or firmware development. The hardest part of the development of LAVA has always been integrating new device types, arising from issues with hardware design and firmware implementations. There are a range of issues with automating new hardware and the experience of the LAVA lab and software teams has highlighted areas where decisions at the hardware design stage have delayed deployment of automation or made the task of triage of automation failures much harder than necessary.

  • ASIFA-Hollywood Continues Commitment to Open-Source Animation Technology

    The International Animated Film Society, ASIFA-Hollywood announced its continued commitment to open-source animation technology earlier in June with a special development sponsorship to Synfig, a 2D vector graphics animation program. The amount awarded was $2,000. This grant will help keep their new developer employed full-time, working on bug-fixes and improving stability of the free and open source software.

  • SD Times Open-Source Project of the Week: FLIR Systems

    FLIR Systems is enabling the acceleration of being able to test thermal sensors on autonomous vehicles with the release of its open-source thermal dataset, which features more than 10,000 annotated thermal images of day and nighttime scenarios.

    The company has over a decade of experience within the automotive industry. More than 500,000 FLIR thermal sensors are installed in driver warning systems from various automakers including General Motors, Volkswagen, Audi, BMW, and Mercedes-Benz, according to the company.

    This dataset will enable developers to evaluate thermal sensors on next-generation algorithms. By combining this data with visible light cameras, LiDAR, and RADAR, developers will be able to build a more comprehensive and redundant system for identifying objects on the road.

  • Keeping Ethereum's Promise: CryptoKitties Is Embracing Open-Source

    Announced this week, CryptoKitties debuted a number of new initiatives that will further decentralize its popular ethereum app, which while largely passing under the radar, show the startup is making strides to give users rights. It's been the subject of criticism for the beloved game, which raised $12 million in March with the expectation it would loosen controls on its code in line with the larger crypto ethos.

    Among a slew of updates, CryptoKitties is open-sourcing its API and smart contracts for gameplay in the KittyVerse – a virtual world of experiences including catfights, racing and accessories – through a developer toolkit. Plus, it's updated its user agreements to be more lenient and introduced a players' rights contract called the Nifty License.

  • CryptoKitties Goes Open Source

    One of the most popular ethereum-based dApp projects, CryptoKitties, has announced several changes and new initiatives to further decentralize the premium virtual feline offering, reports CoinDesk.

    [...]

    In addition, it has also raised questions about whether the project really operates in a truly decentralized manner. For instance, it is possible for Kitty Core, the owner of the CryptoKitties project, to edit the underlying algorithm and mutate a popular or high-worth digital kitten despite objections from the kitten's owner. Essentially, the project runs in a centralized manner, with the project owner(s) having the utmost power.

    It's been another busy week in compiler land for ARM.

    First up, the GCC compiler now officially supports the Cortex-A76. The A76 is the new Cortex processor announced back in May for yielding much better performance and efficiency, especially for AI and machine learning.

  • Compiler fuzzing, part 1

    Much has been written about fuzzing compilers already, but there is not a lot that I could find about fuzzing compilers using more modern fuzzing techniques where coverage information is fed back into the fuzzer to find more bugs.

  • GCC Picks Up Meaningful Bash Completion Support To Help With Compiler Options

    One of the advantages of the LLVM Clang compiler has been better integration with Bash completion support, but now the GCC compiler supports a --completion argument for feeding into the Bash completion script with better matching of supported options/values when typing into a supported terminal.

  • RcppArmadillo 0.8.600.0.0

    A new RcppArmadillo release 0.8.600.0.0, based on the new Armadillo release 8.600.0 from this week, just arrived on CRAN.

    It follows our (and Conrad’s) bi-monthly release schedule. We have made interim and release candidate versions available via the GitHub repo (and as usual thoroughly tested them) but this is the real release cycle. A matching Debian release will be prepared in due course.

  • Chromebooks with Linux app support will soon be able to install Debian packages

    Recent code updates indicate forthcoming support for no-fuss Debian .deb package installation on Chrome OS devices that support Linux apps. The forthcoming feature will bring a new flow for installing Linux applications through .deb packages. A string of commits shows that support isn’t simply being turned on, but that all the finicky elements like interacting with the terminal, checking dependencies, and authentication will be hidden from the user.

  • LTE-enabled Samsung Chromebook on the way, suggest new commits

    Only days after launching the second version of the Chromebook Plus (V2), Samsung seems to be working on one more variant of the Chromebook. In fact, the South Korean giant is now venturing into the always-connected Chromebook market. XDA Developers have unearthed a Coreboot code commit which shows the introduction of a new SKU of Nautilus (which, if you’re not aware is the codename for the Chromebook Plus V2). The commit clearly shows configuration changes that mention LTE support.

  • Google Updates: More Linux Chromebooks, World Cup tags and 'Better Together'

    Another 18 Chromebooks will be able to run Linux apps soon. The plan to roll out the windowed apps, further making them a viable alternative to Windows, now takes in Chrome OS machines from Lenovo, Acer, Asus and Dell joining the frey.

  • Linux Kernel 4.16 Reaches End of Life, Users Are Urged to Upgrade to Linux 4.17

    Just two months after the end of life of the Linux 4.15 kernel series, renowned Linux kernel maintainer Greg Kroah-Hartman announced the end of life of Linux kernel 4.16.

    Back on April 2018, Greg Kroah-Hartman announced the eighteenth point release to the Linux 4.15 kernel series to inform the Linux community that this is the last update that would be released for the branch, urging users to update to the Linux 4.16 kernel series, which appears to have followed the same road.

    Earlier this week, the developer released Linux 4.16.18 as the eighteenth and also the last maintenance update in the series, notifying users that Linux kernel 4.16 is now EOL (End of Life) and won’t receive further updates. Greg Kroah-Hartman urged users to move to a more recent Linux branch, namely the Linux 4.17 kernel series.

  • Linux kernel 4.16 reaches end of life

    Linux kernel maintainer Greg Kroah-Hartman has announced that the Linux 4.16 kernel has reached end of life.

    As reported by Softpedia News, Linux 4.16.18 has been released – and it is the last maintenance update in the series.

    Kroah-Hartman has told users to therefore upgrade to the Linux 4.17 kernel series.

    “This is the LAST 4.16.y kernel release. This branch is now end-of-life. Please move to the 4.17.y kernel now,” he stated in his announcement.

  • Deliverable 1 : [✓]
    Seems okay, far better than the initial results. Although I should say, I deviated from what I thought I would need to write. First I assumed that I don’t have to write another boost::graph wrapper for KisPaintDevice, but I had to. That was one heck of an experience. In one of the last few posts, I ranted on Dmitry’s interpretation of the Graph, turns out we were on the same page but I understood his explanation the wrong way. I should put more attention to details from now on I guess. All the pixels are connected to each other, but they only have an edge between them if they are adjacent. If in center, the out degree would be 8, if in corners, 3 and if in edges, 5. There are some other cases too, but I will leave them for the moment. While writing the wrapper, I also got to know some of the cool features and techniques of C++, which I will be writing posts on as soon as I get some time, concepts, traits, avoiding virtual functions and what not. It is commendable that how boost approaches boost::astar_search, there is not a single virtual function, you don’t have to inherit anything (you can though for safety), just templates and traits, you are done.
  • Go Creeping In
    I’ve seen the inside of the Google and Amazon tech stacks. There are common threads that run through them and also, I bet, through most BigTechCos. Here and there down the stack is a lot of C++ and vestigial remnants from earlier days, Perl or PHP or whatever. Out in front of humans, of course, JS. But in between, there are oceans and oceans of Java; to a remarkable degree, it runs the Internet. Except for, here and there, you find a small but steadily increasing proportion of Go.
  • Stand by for FPR14 SPR1 chemspill
    Mozilla has shipped a fix for MFSA2019-18 in Firefox 67.0.3 and 60.7.1. This exploit has been detected in the wild, and while my analysis indicates it would require a PowerPC-specific attack to be exploitable in official TenFourFox builds (the Intel versions may be directly exploited, however), it could probably cause drive-by crashes and we should therefore ship an urgent fix as well. The chemspill is currently undergoing confidence tests and I'm shooting to release builds before the weekend. For builders, the only change in FPR14 SPR1 is the patch for bug 1544386, which I will be pushing to the repo just as soon as I have confirmed the fix causes no regressions.

All Linux, all the time: Supercomputers Top 500

Starting at the top, two IBM-built supercomputers, Summit and Sierra, at the Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee and Lawrence Livermore National Laboratory in California, respectively to the bottom -- a Lenovo Xeon-powered box in China -- all of them run Linux. Linux supports more hardware architectures than any other operating system. In supercomputers, it supports both clusters, such as Summit and Sierra, the most common architecture, and Massively Parallel Processing (MPP), which is used by the number three computer Sunway TaihuLight. When it comes to high-performance computing (HPC), Intel dominates the TOP500 by providing processing power to 95.6% of all systems included on the list. That said, IBM's POWER powers the fastest supercomputers. One supercomputer works its high-speed magic with Arm processors: Sandia Labs' Astra, an HPE design, which uses over 130-thousand Cavium ThunderX2 cores. And, what do all these processors run? Linux, of course. . 133 systems of the Top 500 supercomputers are using either accelerator or co-processor setups. Of these most are using Nvidia GPUs. And, once more, it's Linux conducting the hardware in a symphony of speed. Read more

  • Kubernetes 1.15: Enabling the Workloads
    The last mile for any enterprise IT system is the application. In order to enable those applications to function properly, an entire ecosystem of services, APIs, databases and edge servers must exist. As Carl Sagan once said, “If you wish to make an apple pie from scratch, you must first invent the universe.” To create that IT universe, however, we must have control over its elements. In the Kubernetes universe, the individual solar systems and planets are now Operators, and the fundamental laws of that universe have solidified to the point where civilizations can grow and take root. Discarding the metaphor, we can see this in the introduction of Object Count Quota Support For Custom Resources. In English, this enables administrators to count and limit the number of Kubernetes resources across the broader ecosystem in a given cluster. This means services like Knative, Istio, and even Operators like the CrunchyData PostgreSQL Operator, the MongoDB Operator or the Redis Operator can be controlled via quota using the same mechanisms that standard Kubernetes resources have enjoyed for many releases. That’s great for developers, who can now be limited by certain expectations. It would not benefit the cluster for a bad bit of code to create 30 new PostgreSQL clusters because someone forgot to add a “;” at the end of a line. Call them “guardrails” that protect against unbounded object growth in your etcd database.

Simple examples paired with the historic background will guide you from the beginning with a minimal Linux environment up to crafting secure containers, which fit perfectly into todays’ and futures’ orchestration world. In the end it should be much easier to understand how features within the Linux kernel, container tools, runtimes, software defined networks and orchestration software like Kubernetes are designed and how they work under the hood.
