  • Acer Chromebook 13 and Chromebook Spin 13 Will Support Linux Apps on Day One

    Acer's recently announced Chromebook 13 and Chromebook Spin 13 appear to be the first Chromebooks to ship with support for Linux apps out-of-the-box at launch.

    Google already announced that it worked on implementing support for Linux apps on Chrome OS during the Google I/O conference last month, and the first Chromebook to run Linux apps is Google's Pixelbook, as expected, and the functionality was later discovered to be available on the Samsung Chromebook Plus as well.

  • Locks in the classroom – 2018

    For the sixth year now, our grade nine students have been doing 3D modeling using Blender. We ran late this year, but the final locks were finished a couple of weeks ago, and they’re finally ready for publishing.

  • CVE-2018-3665: Lazy State Save/Restore As The Latest CPU Speculative Execution Issue

    The latest speculative execution vulnerability affecting modern CPUs has now been made public: Lazy State Save/Restore, a.k.a. CVE-2018-3665.

    This vulnerability concerns saving/restore state when switching between applications. The newly-disclosed vulnerability exploits lazy-state restores for floating-point state when context switching, which is done as a performance optimization, to obtain information about the activity of other applications on the system.

  • AI Is Coming to Edge Computing Devices

    Very few non-server systems run software that could be called machine learning (ML) and artificial intelligence (AI). Yet, server-class “AI on the Edge” applications are coming to embedded devices, and Arm intends to fight with Intel and AMD over every last one of them.

  • Cortex-A76, Mali-G76, and ML chip designs pump up AI

    Arm’s Cortex-A76 design offers speed/efficiency improvements including a 4x boost in AI performance, and is paired with a new Mali-G76 GPU that is also said to aid AI. Meanwhile, Arm revealed more details on its upcoming ML co-processors.

Future Looks Bright for Free Video Editor Lightworks

Naturally changes are coming, as are new features and toolsets to ‘provide a fresh and innovative creative environment’ for content creators. A major update to Lightworks, the first under its new owners, will be available to download in November. It’s not clear (yet) wether Lightworks will remain a “freemium” app (it’s free to download and use but a license is required to unlock 1080p exporting) or if it will be made open source (something Editshare had on their roadmap). Despite being one of best video editors for Linux (it’s available for macOS and Windows too) Lightworks has never quite achieved the sort of user-base that other (equally free) video editors have among ‘hobbyist’ editors. But with the right direction the editor could yet cut through its pro-level competition to better meet the needs demanded by modern content production. Or to put it another way: Lightworks is once again a core software product and not just an extra in someone else’s film. Read more

  • Working With Linked Lists in Python

    Linked lists are like a lesser-known cousin of lists. They’re not as popular or as cool, and you might not even remember them from your algorithms class. But in the right context, they can really shine. If you’re looking to brush up on your coding skills for a job interview, or if you want to learn more about Python data structures besides the usual dictionaries and lists, then you’ve come to the right place!

  • The Python Software Foundation re-opens its Grants Program!

    The Python Software Foundation is excited to announce the re-opening of its Grants Program! The pandemic negatively affected the PSF’s finances with the cancellation of PyCon 2020’s in-person conference and lower donations. Thanks to PyCon 2020 Online sponsors, donors, and our financial reserve, we are able to continue to support the Python community!

  • Fun with SDF records - chemfp's text toolkit

    Earlier this year, Noel O'Boyle wrote the essay Python patterns for processing large SDF files and Richard Apodaca wrote Reading Large SDfiles in Rust. In this essay I'll show some examples of using chemfp's text toolkit API to extract non-chemical/near-chemical data from SDF records. The next essay will be a short one on read_sdf_ids_and_values(), followed by one which is more chemisty focused.

  • ADRIConf Remains The Primary GUI Control Panel For Managing Mesa OpenGL/Vulkan Drivers

    While the Linux kernel graphics drivers and user-space OpenGL/Vulkan drivers expose a lot of options via sysfs on the kernel side and various environment variables and other tunables in user-space, when it comes to graphical control panels to manage these open-source graphics drivers on Linux there are several fragmented different options. For Mesa drivers, ADRIConf remains the leading option. [...] Jean Hertel presented at last week's XDC2020 conference on this utility and its current capabilities with additions in recent years like Vulkan driver support, PRIME GPU handling, MESA_query_driver support, and more.

  • TURNIP Vulkan Driver Up And Running On Qualcomm's KGSL

    The TURNIP driver that is associated with the Freedreno driver effort for providing an open-source Vulkan driver for Qualcomm Adreno graphics hardware can now run atop Qualcomm's KGSL kernel driver. To date this TURNIP Vulkan driver has been working well with the upstream MSM Direct Rendering Manager driver in the Linux kernel, but for those using Qualcomm's official kernel driver (KGSL) that is out-of-tree, it's now a possibility using TURNIP atop that. The Kernel Graphics Support Layer (KGSL) is part of the Android kernel sources and specific to Qualcomm.

  • Felgo in the QML Book

    Over the past year I’ve been bumping into the Felgo crew at various Qt events. They take Qt to the next level. It all started as a game development framework for Qt, but has turned into a powerful app development framework taking a lot of the rough corners of Qt, and extending the tooling with a powerful live reloader at the same time. [...] We also cover a bunch of other things such as how to get started, the QML Live reloader, as well as some more advanced topics such as native dialogs, simplified networking and the JsonListModel.
