  • The AMD Threadripper ECC DDR4-2666 Testing That Wasn't

    Recently in our forums there has been a lot of interest in Threadripper 2 builds using ECC DDR4 memory and the impact on performance, especially now with the Threadripper 2 family being rounded out by the 2920X and 2970WX. So I set out to do some DDR4-2666 ECC UDIMM testing with Threadripper 2, but that hasn't turned out well.

  • Representing KDE at XDC 2018

    Last month the X.Org Developer?s Conference (XDC) was held in A Coru�a, Spain. I took part as a Plasma/KWin developer. My main goal was to simply get into contact with developers from other projects and companies working on open source technology in order to show them that the KDE community aims at being a reliable partner to them now and in the future.

    Instead of recounting chronologically what went down at the conference let us look at three key groups of attendees, who are relevant to KWin and Plasma: the graphics drivers and kernel developers, upstream userland and colleagues working on other compositor projects.

  • It's not okay to pretend your software is open source

    One of my largest complaints with the Commons Clause is that it hijacks language used by open source projects to proliferate nonfree software, and encourages software using it to do the same. Instead of being a new software license, it tries to stick itself onto other respected licences - often the Apache 2.0 license. The name, “Commons Clause”, is also disingenuous, hijacking language used by respected entities like Creative Commons. In truth, the Commons Clause serves to remove software from the commons1. Combining these problems gives you language like “Apache+Commons Clause”, which is easily confused with Apache Commons.

  • Open Source as a Model for Global Education

    While education leaders may be appalled by the closed-border policies coming out of Washington, they often indulge in similar protectionist rhetoric, as highlighted by a recent Wilson Center report.
    The language of “national competitiveness” is common in higher education, especially in discussions of China and the U.S. You hear it in contradictory concerns about too many international students (they will take scarce places at elite institutions! They will steal intellectual property!) and too few (our institutions won't keep up if they stop sending students! We need their tuition to stay afloat!).
    What these worries have in common is the false premise that education is a race and if we don't hurry others will beat us.
    Whereas education competition borrows from the language of economics, an earlier model of educational transfer drew on culture and politics. Transfer was based on importing and exporting from one education system to another. In the 19th and early 20th centuries, American missionaries established colleges across the Middle East and Asia. Philanthropists established international academic exchanges like the Rhodes Scholarship.

  • Chrome OS 70 Brings Better Tablet Mode to Chromebooks, Here’s What’s New

    2-in-1 Chromebooks have existed for a few years now, and have become more and more popular as Chromebooks gained support for touch-based Android apps. But, using a convertible Chromebook just wasn’t as smooth as using a tablet. Part of this was the fact that you’re still holding a laptop, but the bigger part was the user interface.

    Now, both of those problems are effectively solved. Chrome tablets and detachables are available and with Chrome OS 70, there’s a much more touch-friendly user interface.

  • ActiveState Developer Survey Examines Open Source Challenges
  • Report: Developers are not clear on how to get involved in the open-source community

    After 20 years, the open-source community is stronger than ever. However, a recent report found developers while they had more time and know-how to contribute to open-source projects. According the report, respondents don’t quite know where to begin and start to question their skills and time.

    Additionally, developers say they are either too intimidated to contribute, lack the resources, or do not get enough time to contribute from their company.

  • "Every non-free program is an injustice": Richard Stallman on the Free Software Movement

    In the September–October 2018 issue of the New Left Review, Rob Lucas interviews software engineer and free-software advocate Richard Stallman, who is best known for spearheading the development of the GNU/Linux operating system in the 1980s. Stallman began his career at the MIT Artificial Intelligence Lab in the 1970s, which at the time was animated by a spirit of open collaboration and creative exploration. But when the lab began to develop proprietary software and partner with telecommunications companies, Stallman saw the “injustice” of non-free software and struck out on his own.

  • RICHARD STALLMAN TALKING TO THE MAILMAN: Interview by Rob Lucas

    I grew up in Manhattan, born in 1953. I was a behavioural problem—I couldn’t go to a public school without getting in trouble—and started working with computers at an early age. In 1969, during my last year of high school, an IBM lab let me come and use their computers. In 1970 I had a summer job there. They gave me a project to do, implementing a certain algorithm to see how well it would work. I finished that in a few weeks, so they let me spend the rest of the summer being paid to write whatever I felt like. I went to Harvard to study physics, and carried on programming there. Towards the end of my first year I started visiting computer labs to look at their manuals, to see how the computers differed. When I visited the Artificial Intelligence Lab at MIT, they didn’t have much by way of a manual, because they had developed their own time-sharing system. The administrator there decided to hire me more or less straight away. So although I graduated from Harvard in 1974, I had actually been an employee at MIT for three years. Harvard’s computer was a lot better to play with than IBM’s, but it didn’t have a lot of memory, whereas MIT’s computer at the AI Lab had plenty. Not only that, they let me change the time-sharing system; in fact, that was my job—they hired me to work on that system. I added lots of features to lots of different programs—whatever I thought of, or people suggested to me, that seemed like a good idea, I would implement and then people would use it. And this was absolutely delightful—and gratifying to make things that people used and appreciated—so I kept working there. From that point on, I did programming using the machine at MIT.

  • Innovative biography of RMS returns to GNU Press Shop

    In 2002, Sam Williams wrote Free as in Freedom, a biography of Richard M. Stallman. In its epilogue, Williams expressed hope that choosing to distribute his book under the GNU Free Documentation License would enable and encourage others to share corrections and their own perspectives through modifications to his work.

    Free as in Freedom (2.0) is Stallman's revision of the original biography. While preserving Williams's viewpoint, it includes factual corrections and extensive new commentary by Stallman, as well as new prefaces by both authors written for the occasion. It is a rare kind of biography, where the reader has the benefit of both the biographer's original words and the subject's response.

  • Normalizing Filenames and Data with [GNU] Bash

    Yeah, that many years. Almost 13 years of writing about shell scripts and lightweight programming within the Linux environment. I've covered a lot of ground, but I want to go back to something that's fairly basic and talk about filenames and the web.

    It used to be that if you had filenames that had spaces in them, bad things would happen: "my mom's cookies.html" was a recipe for disaster, not good cookies—um, and not those sorts of web cookies either!

    As the web evolved, however, encoding of special characters became the norm, and every Web browser had to be able to manage it, for better or worse. So spaces became either "+" or %20 sequences, and everything else that wasn't a regular alphanumeric character was replaced by its hex ASCII equivalent.

Braiins Systems, the company behind the Slush Pool, has announced Braiins OS. The creators of this bitcoin mining software have claimed that it’s the world’s first fully open source system for cryptocurrency embedded devices.

The initial release of the operating system is based on OpenWrt, which is basically a Linux operating system for embedded devices. You can find its code here.

Those who know about OpenWrt must be aware of the fact that it’s very versatile. As a result, Braiins OS can also be extended in different applications in future.

In a Medium post, Braiins Systems has said that different weird cases of non-standard behavior of mining devices cause tons of issues. With this new mining software, the company wishes to make things easier for mining pool operators and miners.

  • Help test Rust 2018

    Back in July, we talked about “Rust 2018”. In short, we are launching a cycle of long-term milestones called “Editions”. Editions are a way to capture the progress delivered incrementally by our ordinary six-week release cycle – and focus Rust libraries, tooling, and documentation cohesively around it. Editions will be selected roughly every three years: Rust 1.0 was “Rust 2015” and Rust 1.31 will be “Rust 2018”. Each edition has a theme; Rust 2015’s was “stability”, and Rust 2018’s is “productivity.”

    We’ve been testing Rust 2018 for a while already, and things are looking pretty good! We have just under six weeks until Rust 1.31 ships, and so we’d appreciate it if you could give the beta a try.

  • Remap custom keyboard keys in Linux - Tutorial

    Modern problems require modern solutions. I've recently got meself a new Linux test laptop, one IdeaPad 3, which I bought (unfortunately, due to market shortages) with the UK keyboard layout instead of the US layout. This means suboptimal physical key placement - even if you do use a different keyboard variant. Namely, the bar and backspace keys and such are placed all wrong, plus the Enter key is too small. Moreover, this also means, muscle memory and all, you end up typing \ when you actually want to jump to a new line, and this can be quite annoying. So I thought, perhaps I can remap keyboard keys in a small way? But I didn't want to just remap the backspace key (bearing the UK tilde and hash symbols) to a "second" Enter, thus effectively making a larger Enter key, I still wanted to have the bar and backspace keys available. Hence a more complex exercise. Let me show you how you can this somewhat convoluted but super-nice setup.

  • Linux server certifications becoming a must-have for IT pros | Network World

    Linux certification is increasingly significant for tech workers as the public cloud and software-defined networking become ever more important. A Linux cert can set IT professionals apart from the herd and potentially put a lot more money in their bank accounts. Once these certifications were a gauge of reliability, according to CompTIA chief tech evangelist James Stanger. “Twenty years ago, Linux tended to attract people who were a little edgier,” he said. “So certification was traditionally used in the Linux side just to find people you can work with—will they show up on time?” Now, these certifications are a demonstration not only of proficiency but also dedication to self-improvement. “You can’t go wrong with a certification,” said Joe Faletra, director of infrastructure services at Modis, a technology staffing and consulting firm. “I’ll lean towards certs over experience [in hiring], because this person has put the effort into learning and passing the exam.”

We have pre-configurations for Enlightenment, i3, LXDE, and MATE as well. [...] When we use Kali, we spend a significant amount of time using the command line. A lot of the time, we do it using a local terminal (rather than in a console or remote SSH).

Kernel: Millennium Prize, Compute Express Link 2.0, HP Platform Profile Support

  • Millennium prize problems but for Linux

    There is a longstanding tradition in mathematics to create a list of hard unsolved problems to drive people to work on solving them. Examples include Hilbert's problems and the Millennium Prize problems. Wouldn't it be nice if we had the same for Linux? A bunch of hard problems with sexy names that would drive development forward? Sadly there is no easy source for tens of millions of euros in prize money, not to mention it would be very hard to distribute as this work would, by necessity, be spread over a large group of people. Thus it seems is unlikely for this to work in practice, but that does not prevent us from stealing a different trick from mathematicians' toolbox and ponder how it would work in theory. In this case the list of problems will probably never exist, but let's assume that it does. What would it contain if it did exist? Here's one example I came up with. it is left as an exercise to the reader to work out what prompted me to write this post. [...] A knee-jerk reaction many people have is something along the lines of "you can solve this by limiting the number of linker processes by doing X". That is not the answer. It solves the symptoms but not the underlying cause, which is that bad input causes the scheduler to do the wrong thing. There are many other ways of triggering the same issue, for example by copying large files around. A proper solution would fix all of those in one go.

    Immediately following the publishing of the Linux enablement patches for CXL 2.0 and that continued in the months since over several rounds of patches. That initial CXL 2.0 code is now slated for mainlining with the Linux 5.12 kernel. The initial Compute Express Link 2.0 focus for the Linux kernel has been on supporting Type-3 Memory Devices. The CXL 2.0 type-3 memory device support being fleshed out first is for serving as a memory expander for RAM or persistent memory and can optionally be interleaved with other CXL devices. For the lack of any CXL 2.0 hardware yet even within the confines of Intel, Widawsky worked out this initial enablement code thanks to writing up support around the specification within QEMU for emulation.
