  • 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.

  • 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.

  • 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.

  • Parler Tricks: Making Software Disappear

    Much has been written and broadcast about the recent actions from Google and Apple to remove the Parler app from their app stores. Apps get removed from these app stores all the time, but more than almost any past move by these companies, this one has brought the power Big Tech companies wield over everyone’s lives to the minds of every day people. Journalists have done a good job overall in presenting the challenges and concerns with this move, as well as addressing the censorship and anti-trust issues at play. If you want a good summary of the issues, I found Cory Doctorow’s post on the subject a great primer. [...] This is part of the article where Android users feel smug. After all, while much more of their data gets captured and sold than on iOS, in exchange they still (sometimes) have the option of rooting their phones and (sometimes) “sideloading” applications (installing applications outside of Google’s App Store). If Google bans an app, all a user has to do is follow a list of complicated (and often sketchy) procedures, sometimes involving disabling protections or installing sketchy software on another computer, and they can wrench back a bit of control over their phones. Of course in doing so they are disabling security features that are the foundation for the rest of Android security, at which point many Android security experts will throw up their hands and say “you’re on your own.” [...] The Librem 5 phone runs the same PureOS operating system as Librem laptops, and it features the PureOS Store which provides a curated list of applications known to work well on the phone’s screen. Even so, you can use the search function to find the full list of all available software in PureOS. After all, you might want that software to be available when you dock your Librem 5 to a larger screen. We aim to provide software in the PureOS store that respects people’s freedom, security, and privacy and will audit software that’s included in the store with that in mind. That way people have a convenient way to discover software that not only works well on the phone but also respects them. Yet you are still free to install any third-party software outside of the PureOS Store that works on the phone, even if it’s proprietary software we don’t approve of.

  • Apple Mulls Podcast Subscription Push Amid Spotify's Land Grab

    The talks, first reported by The Information, have been ongoing since at least last fall, sources tell to The Hollywood Reporter, and ultimately could end up taking several different forms. Regardless, it’s clear that Tim Cook-led Apple — after spending the last two years watching rival-in-music-streaming Spotify invest hundreds of millions of dollars to align itself with some of the most prolific producers and most popular personalities in podcasting — is no longer content sitting on the sideline. “There’s a huge opportunity sitting under their nose with 1.4 million iOS devices globally,” says Wedbush Securities analyst Daniel Ives, “and they don’t want to lose out.” Apple declined to comment about its podcasting plans.

    Much of the growth of the podcasting industry over the last decade can be traced back to Apple and its former CEO Steve Jobs, who in 2005 declared that he was “bringing podcasting mainstream” by adding support for the medium to iTunes. A few years later, the company introduced a separate Podcasts app that quickly became the leading distribution platform for the medium. But Apple, which netted $275 billion in sales in fiscal 2020, has refrained from turning podcasting — still a relatively small industry that the Interactive Advertising Bureau estimated would bring in nearly $1 billion in U.S. advertising revenue last year — into a moneymaking venture.

  • the tragedy of gemini

    While everything I have seen served via Gemini is friendly and sociable, the technical barriers of what-is-a-command-line and how-do-I-use-one are a fence put up that keep out the riffraff. Certainly, you can walk around the corner and go through the gate, but ultimately the geminiverse is lovely because it is underpopulated, slower-paced, and literate. It is difficult enough to access that those who can use it can be welcoming without worrying its smallness will be compromised.

    The tragedy is that I don’t think many of its denizens would claim that they only want to hear from technical, educated people, but in order to use a small [Internet], an August [Internet], they have let the fence keep out anyone else.

  • C++ Operator Overloading – Linux Hint

    This article provides a guide to operator overloading in C++. Operator overloading is a useful and powerful feature of the C++ programming language. C++ allows overloading of most built-in operators. In this tutorial, we will use several examples to demonstrate the operator overloading mechanism. [...] The C++ language allows programmers to give special meanings to operators. This means that you can redefine the operator for user-defined data types in C++. For example, “+” is used to add built-in data types, such as int, float, etc. To add two types of user-defined data, it is necessary to overload the “+” operator.

  • Lua, a misunderstood language

    Lua is one of my favourite programming languages. I’ve used it to build a CMS for my old educational website, for creating cool IoT hardware projects, for building little games, and experimenting with network decentralisation. Still, I don’t consider myself an expert on it at all, I am at most a somewhat competent user. This is to say that I have had exposure to it in various contexts and through many years but I am not deep into its implementation or ecosystem. Because of that, it kinda pains me when I read blog posts and articles about Lua that appear to completely miss the objective and context of the language. Usually these posts read like a rant or a list of demands. Most recently, I saw a post about Lua’s Lack of Batteries on LWN and a discussion about that post on Hacker News that made me want to write back. In this post I’ll address some of the comments I’ve seen on that original article and on Hacker News.

Since old GTK2 and Python 2 libraries being removed from Ubuntu universe repositories, the Python script support was excluded due to lack of dependencies when I was uploading the GIMP packages into PPA. Ubuntu 18.04 was neglected, though. It meets all the dependencies to build the requested feature. So I added it back. Hope it’s not too late for you :).

  • Linux Release Roundup: Kdenlive 20.12.1, BleachBit 4.2.0 & LibreOffice 7.1 RC - OMG! Ubuntu!

    I’m keen to get back into the habit of posting Linux release roundups. The last one I wrote was way back in 2019 — so it’s been a while! [...] Well, open source and Linux-focused development never stops. App, tool, kernel, driver, distro, and framework updates pop out each and every week. Not all of these updates are what you’d call ‘substantial’ or ‘must-read’ news. Point releases, for instance, are difficult to “pad out” into a full length article (much less sound like one you’d want to read about). I’m loathe to start firing out 8 short posts a day on thin topics. It clogs up your feed reader and pushes genuinely interesting content off the main page. Hence the roundups. I get the satisfaction of being able to cover the “lite” news items I normally skip (and mention distro releases I might not normally be able to), and you get the satisfaction of knowing you’re missing out on even less stuff. Keen to see what meaty chunks are threaded on this week’s skewer? Read on…
