Sci/Tech

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.

Black Hole Image Has an Open Source Connection

  • Black Hole Image Has an Open Source Connection

    Two imaging libraries responsible for the image are fully open source.

    Last week the whole world was stunned by seeing what was unseen – a black hole. Scientists were able to create picture of a black hole named Messier 87 in the Virgo A galaxy. The black hole is more than 55 million light years away.

    The first image of a black hole is the outcome of the Event Horizon Telescope (EHT) project, which created a virtual telescope as big as earth by networking 8 ground-based telescopes. The telescopes generated more than five petabyte of data. Collecting data was the first part of the puzzle. The team of scientists used various algorithms to fill gaps in this data to be able to generate an image of the black hole.

Ubuntu Leftovers: Blobs, Snapcraft and Arronax

  • Ubuntu 19.10 To Bundle NVIDIA's Proprietary Driver Packages As Part Of Its ISO
    For Ubuntu 19.10 the developers are adding the NVIDIA driver packages onto the ISO. The NVIDIA binary drivers won't be activated by default, but will be present on the install media to make it easier to enable post-install. The open-source NVIDIA "Nouveau" drivers will remain the default for NVIDIA graphics on new Ubuntu installations, but this change is positioning the mainline and legacy NVIDIA proprietary drivers onto the Ubuntu ISO so that they can be easily obtained locally post-install. The main driver here is allowing users to enable the NVIDIA proprietary graphics on Ubuntu even if you don't have an Internet connection. NVIDIA has already okay'ed the distribution of their driver packages with the Ubuntu ISO.
  • Snapcraft parts & plugins
    Last week, we published Introduction to snapcraft, a tutorial that provided a detailed overview of the snap build process. We touched on the concepts like snap ecosystem components, snapcraft command line, snapcraft.yaml syntax, and more. We’d like to expand on the first lesson, and today, we are going to talk about parts and plugins, used in the build process of snaps.

  • Valve's Proton Pulls In Latest DXVK, Steam Networking Updates, Controller Layout Fixes
    The Valve developers maintaining their Proton fork of Wine for use by Steam Play have outed a new update, version 4.2-5.
  • Wine & Mingw-w64 Might Tighten Up Their Relationship - Possible "WineSDK"
    Developers between the Wine and Mingw-w64 projects are discussing the potential for further embracing their relationship given the overlap in trajectory and both benefiting from close collaboration. This extended relationship could also involve Mingw-w64 potentially adopting Wine's branding. While all Phoronix readers should be aware of Wine, for those not familiar with Mingw-w64 it's the off-shoot of MinGW focused on 64-bit support and other features over the original MinGW for providing an open-source development toolchain for Microsoft Windows. Mingw-w64 remains quite active in working on its GCC-based compiler toolchain support for Windows.

  • IRKALLA, an incredibly stylish looking pixel-art tactical-action platformer is coming to Linux
    The developers behind IRKALLA emailed in today and it grabbed my interest right away with the supremely stylish art behind it. The odd setting has my curiosity too, with mechs versus demons! According to the developer, it's a "platform-tactic game" so it has elements of an action platformer with character progression and some form of base defence building. IRKALLA has been in development for quite a few years now with their TIGForum post dating all the way back to 2013. We've been emailed today, as it seems development on it has been picked back up as they told me it's "finally coming together" and a Linux release is also confirmed of course.
  • Roguelike fantasy adventure 'Vambrace: Cold Soul' has a new feature trailer ahead of release next week
    The release of Vambrace: Cold Soul on May 28th is getting close now, it's quite an impressive looking game that I've been playing and they have a new feature trailer. I won't say too much on it myself before release but since I've had access for a while, I can say it works great on Linux.
  • Surreal adventure game 'ZED' about an artist suffering from dementia is releasing in June
    ZED, a game that will tell the story of an artist suffering from dementia from Eagre Games and Cyan Ventures now has a release date and it's quite soon. The Windows version is now scheduled in for June 4th, with the Linux (and Mac) version to be "later in June". Great to see it continue to be confirmed and although there is a delay, it's not going to be long it seems. Good thing too, as I'm damn excited for this one.
  • art of rally is bringing a stylized racing experience to Linux later this year
    Funselektor Labs, the developer of Absolute Drift has announced their latest game, art of rally. It might look stylish but it's not just a pretty face, as the developer is also focused on how the cars handle too. While we have a few racing games now like Grid Autosport, DiRT Rally/4 and some F1 games (plus a few that work with Steam Play), they're all quite serious business. art of rally looks to be taking a slightly less realistic focus while still providing a challenge, especially with the top-down view you get a better picture of what's up ahead.
