  • Arm SVE2 Support Aligning For GCC 10, LLVM Clang 9.0

    Given the significant performance benefits to Arm's Scalable Vector Extension 2 (SVE2), they are working on ensuring the open-source Linux compiler toolchains support these new CPU instructions ahead of SoCs shipping that support this big addition.

    Arm announced Scalable Vector Extension 2 (SVE2) recently as their latest advancement around SIMD programming and increasing data-level parallelism in programs. SVE2 is designed to ultimately deliver better SIMD performance than their long-available Neon extensions and to scale the performance with vector length increases as well as enabling auto-vectorization techniques. More details in this post on SVE2.

  • Intake: Discovering and Exploring Data in a Graphical Interface

    Do you have data that you’d like people to be able to explore on their own? Are you always passing around snippets of code to load specific data files? These are problems that people encounter all the time when working in groups and using the same datasources or when trying to distribute data to the public. Some users are comfortable interacting with data entirely programatically, but often it is helpful to use a GUI (Graphical User Interface) instead. With that in mind we have reimplemented the Intake GUI so that in addition to working in a jupyter notebook, it can be served as a web application next to your data, or at any endpoint.

  • lightening run-time code generation

    The upcoming Guile 3 release will have just-in-time native code generation. Finally, amirite? There's lots that I'd like to share about that and I need to start somewhere, so this article is about one piece of it: Lightening, a library to generate machine code.

  • Python Language Creator: “Male Attitude” Is Hurting The Programming Space

    Guido van Rossum is a famous name in the programming world. He is the creator of the Python programming language which was developed back in 1989. It is only since the last few years when this general-purpose programming language started gaining popularity.

    The number of Python users has increased significantly and it was not only named as the best programming language by IEEE but also the most asked-about language on Stack Overflow, overthrowing JavaScript — the all-time winner for decades.

Games: vkBasalt, Ikey Doherty, Crusader Kings II, Sunless Skies

  • vkBasalt, an open source Vulkan post processing layer for Contrast Adaptive Sharpening

    This is an interesting open source project! vkBasalt is a new Vulkan post processing layer that currently supports Contrast Adaptive Sharpening. Unlike Radeon Image Sharpening, vkBasalt supports Linux and works with both NVIDIA and AMD. This isn't entirely reinventing the wheel though, as it's partly based upon the ReShade port of AMD's CAS. Still, it's fun to see what hackers are able to do with little layers like this, especially when we don't have official support.

  • Ikey Doherty Launches Open-Source Focused Game/Software Development Company

    Well known open-source figure Ikey Doherty who rose to prominence for his work on the Solus Linux distribution and then went on to work on Intel's Clear Linux project is now having his hand at game engine development. Ikey shared with us that he left Intel back in May to begin his new adventure: Lispy Snake. Lispy Snake is a UK software development firm that at least initially is working on a game engine and games. Given Ikey's experience, the firm is focused on leveraging open-source technologies.

  • After making Crusader Kings II free, Paradox are now giving away The Old Gods expansion

    It's been a bit of a whirlwind of Paradox news recently and we have even more to share. With a tiny amount of effort, you can get The Old Gods expansion for Crusader Kings II free. This is after Crusader Kings II was set free to play and Crusader Kings III was announced just like I suggested it would be.

  • Failbetter Games are upgrading owners of Sunless Skies to the Sovereign Edition next year

    Failbetter Games have announced that Sunless Skies is getting a bit of an upgrade with the Sovereign Edition and it's going to be free to existing purchasers when it's release next year. Part of the reason, is that it will be releasing on Consoles so they're polishing the experience up some more. It's not just a special console edition though, it's coming with a bunch of new content and various improvements to the flow of it. To release on PC at the same time as Consoles, free for existing players.

What To Do After Installing Ubuntu 19.10 Eoan Ermine

In this traditional article special for Ubuntu 19.10 Eoan Ermine you will find my suggestions and recommendations in 3 parts, work (including date/time adjustments, productivity tools), non-work (including extensions, podcasts, RSS, codecs), and system maintenance (including CPU-X, repository setup, auto-backup). I also have suggestion for you wanting Global Menu on this Eoan Ermine OS at the end. Adjust it once and use freely everyday. Finally, I hope Ubuntu 19.10 will be your best tool you could imagine to use without worry. Happy working! Read more

Python Programming Leftovers

  • Pylint: Making your Python code consistent

    Pylint is a higher-level Python style enforcer. While flake8 and black will take care of "local" style: where the newlines occur, how comments are formatted, or find issues like commented out code or bad practices in log formatting. Pylint is extremely aggressive by default. It will offer strong opinions on everything from checking if declared interfaces are actually implemented to opportunities to refactor duplicate code, which can be a lot to a new user. One way of introducing it gently to a project, or a team, is to start by turning all checkers off, and then enabling checkers one by one. This is especially useful if you already use flake8, black, and mypy: Pylint has quite a few checkers that overlap in functionality.

  • PyDev of the Week: Sophy Wong

    This week we welcome Sophy Wong (@sophywong) as our PyDev of the Week! Sophy is a maker who uses Circuit Python for creating wearables. She is also a writer and speaker at Maker events. You can see some of her creations on her Youtube Channel or her website. Let’s take a few moments to get to know her better!

    In this short post, we are going to learn how to turn the code from blog posts to Jupyter notebooks.

Proper Linux Screen Sharing Coming to Chromium & Electron Apps like Discord

A patch to add ‘screen enumeration’ to the Chromium browser is currently pending merge upstream. Once this fix is accepted Chromium and Chromium-based apps (like Discord) will finally support full screen sharing on Linux in a manner similar to that on Windows and macOS. Not being a multi-monitor user, or someone who shares their screen often, I wasn’t aware of this particular limitation until recently. So I’ll explain. Read more
