Sci/Tech
  • SQLite Release 3.28.0
  • SQLite 3.28 Released With More Feature Additions, Performance Enhancements

    SQLite 3.28 is now the latest version of this widely-used, embed-friendly cross-platform database library.

    As is the case for most SQLite releases, new features and performance enhancements are the principle changes. SQLite 3.28 presents enhanced window functions, enhancements to its TCL interface, various CLI improvements, new API additions, security improvements to its tokenizer, more robust handling against corrupt database files, and various fixes.

  • Gnuastro 0.9 released

    I am happy to announce the 9th stable release of GNU Astronomy
    Utilities (Gnuastro).

    Gnuastro is an official GNU package consisting of various command-line
    programs and library functions for the manipulation and analysis of
    (astronomical) data. All the programs share the same basic
    command-line user interface (modeled on GNU Coreutils). For the full
    list of Gnuastro's library, programs, and a comprehensive general
    tutorial (recommended place to start using Gnuastro), please see the
    links below respectively:

    https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-library.html
    https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-programs-list.html
    https://www.gnu.org/s/gnuastro/manual/html_node/General-program-usage-tutorial.html

    Many features have been added and Gnuastro has become much more stable
    with the many bugs that were found and fixed (see [1], below). The most
    interesting new feature may be that Gnuastro now also installs scripts
    (with this naming convention: `astscript-*'). Since Gnuastro's
    programs are designed to be highly modular, they are relatively
    low-level. With this new feature, it is now very easy to include
    common higher-level operations within Gnuastro also, for example to
    call multiple programs together, or use a single program's outputs in
    a special way. With version 0.9, only one script is installed (as
    described in [1]), but because of their high-level nature, we expect
    many more to be added soon. If you commonly run several Gnuastro
    programs together for a certain operation, please share it with us so
    we add it as a script for everyone to use.

Scientists have finally seen what could not have been seen – a black hole. As fascinating is the fact that we can now ‘see’ a black hole, the story behind this achievement is even more fascinating.

It’s a story of victory of science in the political era of science denials. It’s a victory of diversity in the era of homophobia and sexism. It’s a victory of free software in the era of…well, we live in the era of free software.

KDE Cantor - Sing me some math

Filed under
KDE
Software
Sci/Tech

It's a song, but it needs refinement. Cantor seems like a clever piece of software, but it lacks refinement and sophistication to match its own goals. I did only test Octave, but I think my findings are pretty indicative. After all, if there were issues with one backend, whatever they are, they need to be fixed. And these weren't trivial issues, either. Slow performance, memory and CPU noise, frozen interface, bad-looking figures.

The configuration also needs to be improved. All in all, it's very difficult doing what Cantor tries, so the idea is really cool. But it seems to be a complex task, and at the moment, it brings more woes than benefits. I'd like to see a smoother integration, and a clever wizard that lets you add backends. Maybe a smart clipboard to share code with other programs. I'd expect a fully HW-accelerated graphics module, so everything responds fast and looks peachy. Finally, Cantor mustn't work any worse than the native engines it represents, because it invalidates its own purpose by doing that (or rather not doing that, hi hi). At the moment, it's a raw product, and it needs a lot of fixes. But me likey, so I will be testing in the future. Unique software, here I go.

The Raspberry Pi Cluster from Outer Space

Hardware
Sci/Tech

We see a lot of weird and esoteric stuff here at Hackaday, but even by our standards, Bell Lab’s Plan 9 operating system is an oddball. Named after the science fiction film Plan 9 from Outer Space, it was designed to extend the UNIX “everything is a file” mentality to the network. It envisioned a future where utilizing the resources of another computer would be as easy as copying a file. But as desktop computers got more powerful the idea seemed less appealing, and ultimately traditional operating systems won out. Of course, that doesn’t mean you still can’t play around with it.

Astronomy Software by Any Other Name

Filed under
Software
Sci/Tech

In this article, I introduce another option available for the astronomers out there—specifically, Cartes du Ciel, also known as SkyChart. Similar to other larger astronomy programs, you can use SkyChart from the desktop to the observatory.

SkyChart probably won't be available in your distribution's package management system, so you'll need to go to the main website to download it. DEB, RPM and TAR files are available, so you should be able to use it for just about any distribution. Downloads also are available for other operating systems and for other hardware. You even can download a version to run on a Raspberry Pi.

When you first start Cartes du Ciel, you'll be asked where on the globe your observatory is located.

  • 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, a 2D action-RPG with a gorgeous vibrant style will be coming to Linux next year

Taking inspiration from classics like Legend of Zelda: A link to the past, Secret of Mana, Chrono Trigger and a ton more you can see it quite clearly. 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.
