  • Moving to GitLab! Yes, it's worth it!

    I started evangelizing Git in 2007. It was a very tough sell to make at the time.

    Outside of the kernel development almost no one wanted to learn it and we had very worthy competitors, from Subversion, to Mercurial, to Bazaar, to Darcs, to Perforce, and so on. But those of use that dug deeper knew that Git had the edge and it was a matter of time.

    Then GitHub showed up in 2008 and the rest is history. For many years it was just "cool" to be in GitHub. The Ruby community drove GitHub up into the sky. Finally it became the status quo and the one real monopoly in information repositories - not just software source code, but everything.

    I always knew that we should have a "local" option, which is why I tried to contribute to Gitorious way back in 2009. Other options arose, but eventually GitLab appeared around 2011 and picked up steam in the last couple of years.

Snap! — Beyond teaching coding to would-be programmers

Filed under
Development

Block-based programming languages are not the be-all and end-all of Computer Science learning and they are not meant to be. You could use them without ever intending your students pursue a career in programming. For those who do want to become developers, tools like Snap! are a good starting point from which to get a handle on complex programming concepts, such as OOP, modularity, events, and so on. For other students, they provide a fun and consistent way of training your brain for logical reasoning and out-of-the-box problem solving.

  • JavaScript keeps its spot atop programming language rankings

    U.K.-based technology analyst firm RedMonk just released the latest version of its biannual rankings of programming languages, and once again JavaScript tops the list, followed by Java and PHP.

    Those are same three languages that topped RedMonk’s list in January. In fact, the entire top 10 remains the same as it was it was six months ago. Perhaps the biggest surprise in Redmonk’s list—compiling the “performance of programming languages relative to one another on GitHub and Stack Overflow”—is that there are so few surprises, at least in the top 10.

  • Plenty of fish in the C, IEEE finds in language popularity contest

    It's no surprise that C and Java share the top two spots in the IEEE Spectrum's latest Interactive Top Programming Languages survey, but R at number five? That's a surprise.

    This month's raking from TIOBE put Java at number one and C at number two, while the IEEE reverses those two, and the IEEE doesn't rank assembly as a top-ten language like TIOBE does.

    It's worth noting however that the IEEE's sources are extremely diverse: the index comprises search results from Google, Twitter, GitHub, StackOverflow, Reddit, Hacker News, CareerBuilder, Dice, and the institute's own eXplore Digital Library.

    Even then, there are some oddities in the 48 programming environments assessed: several commenters to the index have already remarked that “Arduino” shouldn't be considered a language, because code for the teeny breadboard is written in C or C++.

  • TensorFlow CPU optimizations in Anaconda

    By Stan Seibert, Anaconda, Inc. & Nathan Greeneltch, Intel Corporation TensorFlow is one of the most commonly used frameworks for large-scale machine learning, especially deep learning (we’ll call it “DL” for short). This popular framework has been increasingly used to solve a variety of complex research, business and social problems. Since 2016, Intel and Google have worked together to optimize TensorFlow for DL training and inference speed performance on CPUs. The Anaconda Distribution has included this CPU-optimized TensorFlow as the default for the past several TensorFlow releases. Performance optimizations for CPUs are provided by both software-layer graph optimizations and hardware-specific code paths. In particular, the software-layer graph optimizations use the Intel Math Kernel Library for Deep Neural Networks (Intel MKL-DNN), an open source performance library for DL applications on Intel architecture. Hardware specific code paths are further accelerated with advanced x86 processor instruction set, specifically, Intel Advanced Vector Extensions 512 (Intel AVX-512) and new instructions found in the Intel Deep Learning Boost (Intel DL Boost) feature on 2nd generation Intel Xeon Scalable processors. Let’s take a closer look at both optimization approaches and how to get these accelerations from Anaconda.

    I have many problems with YouTube, who doesn’t these days, right? I’m not going to go into all the nitty gritty of it in this post, but here’s a video from a LBRY advocate that does a good job of summarizing some of the issues by using clips from YouTube creators: I have a channel on YouTube for which I have lots of plans for. I started making videos last year and created 59 episodes for Debian Package of the Day. I’m proud that I got so far because I tend to lose interest in things after I figure out how it works or how to do it. I suppose some people have assumed that my video channel is dead because I haven’t uploaded recently, but I’ve just been really busy and in recent weeks, also a bit tired as a result. Things should pick up again soon.

Games: Steam Summer Sale, Last Moon, Ubuntu-Valve-Canonical Faceoff

  • Steam Summer Sale 2019 is live, here’s what to look out for Linux fans

    Another year, another massive sale is now live on Steam. Let’s take a look at what Valve are doing this year and what you should be looking out for. This time around, Valve aren’t doing any special trading cards. They’re trying something a little different! You will be entering the "Steam Grand Prix" by joining a team (go team Hare!), earning points for rewards and having a shot at winning some free games in the process. Sounds like a good bit of fun, the specific-game challenges are a nice touch.

Last Moon takes in place in a once peaceful kingdom, where an ancient and powerful mage put a curse on the moon, as Lunar Knight you need to stop all this insanity and bring back peace.

  • Ubuntu Takes A U-Turn with 32-Bit Support

    Canonical will continue to support legacy applications and libraries. Canonical, the maker of the world’s most popular Linux-based distribution Ubuntu, has revived support for 32-bit libraries after feedback from WINE, Ubuntu Studio and Steam communities. Last week Canonical announced that its engineering teams decided that Ubuntu should not continue to carry i386 forward as an architecture. “Consequently, i386 will not be included as an architecture for the 19.10 release, and we will shortly begin the process of disabling it for the eoan series across Ubuntu infrastructure,” wrote Will Cooke, Director of Ubuntu Desktop at Canonical.

  • Steam and Ubuntu clash over 32-bit libs

    It has been a tumultuous week for gaming on Linux. Last Tuesday afternoon, Canonical's Steve Langasek announced that 32-bit libs would be frozen (kept as-is, with no new builds or updates) as of this October's interim 19.10 release, codenamed "Eoan Ermine." Langasek was pretty clear that this did not mean abandoning support for running 32-bit applications, however.

  • Linux gamers take note: Steam won’t support the next version of Ubuntu

    Valve has announced that from the next version of Ubuntu (19.10), it will no longer support Steam on Ubuntu, the most popular flavor of Linux, due to the distro dropping support for 32-bit packages, This all kicked off when Canonical, developer of Ubuntu, announced that it was seemingly completely dropping support for 32-bit in Ubuntu 19.10. However, following a major outcry, a further clarification (or indeed, change of heart) came from the firm stating that there will actually be limited support for 32-bit going forward (although updates for 32-bit libraries will no longer be delivered, effectively leaving them in a frozen state).

  • Valve killing Steam Support for some Ubuntu users

    A few years ago the announcement that Steam would begin supporting Linux was a big deal: it meant that anyone who preferred to rock an open-source operating system over Mac OS or Windows 10 would have instant buy-it-and-play-it access to a large catalog of game titles that would have otherwise taken a whole lot of tweaking to get up and running or wouldn't have worked for them at all. For some, at least, the party may be coming to an end.

  • Steam is dropping support for Ubuntu, but not Linux entirely

    The availability of Steam on Linux has been a boom for gaming on the platform, especially with the recent addition of the Steam Play compatibility layer for running Windows-only games. Valve has always recommended that gamers run Ubuntu Linux, the most popular desktop Linux distribution, but that's now changing.

  • Canonical (sort of) backtracks: Ubuntu will continue to support (some) 32-bit software

    A few days after announcing it would effectively drop support for 32-bit software in future versions of the Ubuntu operating system, Canonical has decided to “change our plan and build selected 32-bit i386 packages.” The company’s original decision sparked some backlash when it became clear that some existing apps and games would no longer run on Ubuntu 19.10 if the change were to proceed as planned. Valve, for example, announced it would continue to support older versions of Ubuntu, allowing users to continue running its popular Steam game client. But moving forward, the company said it would be focusing its Steam for Linux efforts on a different GNU/Linux distribution.

  • Just kidding? Ubuntu 32-bit moving forward, no word yet from Valve

    Due in part to the feedback given to the group over the weekend and because of their connections with Valve, Canonical did an about-face today. They’ve suggested that feedback from gamers, Ubuntu Studio, and the WINE community led them to change their plan and will “build selected 32-bit i386 packages for Ubuntu 19.10 and 20.04 LTS. Whether this will change Valve’s future with Ubuntu Steam, we’ll see.

  • Canonical backtracks on 32-bit Ubuntu cull, but warns that on your head be it

    CANONICAL HAS CONFIRMED a U-Turn on the controversial decision to drop 32-bit support for Ubuntu users later this year. The company has faced criticism from users who aren't happy with the plan to make Ubuntu purely 64-bit, which culminated at the weekend with Steam announcing it would pull support for Ubuntu. Many Steam games were never made in 64-bit and it would, therefore, devalue the offer. However, Canonical confirmed on Monday that following feedback from the community, it was clear that there is still a demand, and indeed a need for 32-bit binaries, and as such, it will provide "selected" builds for both Ubuntu 19.10 and the forthcoming Ubuntu 20.04. Canonical's announcement spoke of the highly passionate arguments from those who are in favour of maintaining both versions, thus forcing the team to take notice. However, it has made it clear that it's doing so under the weight of expectation, not because it agrees. "There is a real risk to anybody who is running a body of software that gets little testing. The facts are that most 32-bit x86 packages are hardly used at all," the firm said.
