  • Best Free Books to Learn about Scratch

    Scratch is a visual programming language developed by the Lifelong Kindergarten Group at the MIT Media Lab. Scratch teaches programming concepts to kids, offering a stepping stone to more complicated programming languages. Coding includes dragging and dropping various code blocks and linking them together like jigsaw pieces to form logical scripts. While the MIT Media Lab designed this language for 8-16 year-old children, it is used by people of all ages.

    Scratch has received many plaudits as an ideal way to introduce kids to computer programming and computational thinking. It’s a fantastic beginner’s language. Scratch is often used to make games, interactive stories, and animations, but it can be used for any purpose. The language uses event-driven programming with multiple active objects. The language helps students to think creatively, reason logically, and work together. The language is frequently used in schools, libraries, community centres, and museums.

    Scratch is released under an open source license. I recommend 7 free books that really help young people master Scratch. These recommended texts are also open source goodness.

  • Introducing The New Librem Chat

    Social good, freedom personal privacy and security are things you take seriously (and probably think everyone else should, too). And maybe you already know that the Librem Chat is part of Librem One, a suite of privacy-protecting, no-tracking apps and services which aim to make the world a better place.

  • Top Android Apps to Remote Control Your Linux Desktop

    Remote Access/Control software is important for convenience and/or emergency purposes because it enables users to control their computer systems from the convenience of their couch, for example.

    Earlier this year, I covered the 10 best TeamViewer alternatives for Linux so today, let’s turn our attention to smartphones as I introduce you to the best remote control Android apps for Linux.

    [...]

    KDE Connect is a free and open source end-to-end TLS encrypted utility for remotely controlling Linux desktops, sharing files and controlling media players over a Wi-Fi connection. With it, you can share files, URLs, and clipboard content between your computer and any app, read SMS notifications and get call alerts.

  • FOSS Project Spotlight: Bareos, a Cross-Network, Open-Source Backup Solution

    Bareos (Backup Archiving Recovery Open Sourced) is a cross-network, open-source backup solution that preserves, archives and recovers data from all major operating systems. The Bareos project started 2010 as a Bacula fork and is now being developed under the AGPLv3 license.

    The client/server-based backup solution is actually a set of computer programs (Figure 1) that communicate over the network: the Bareos Director (BD), one or more Storage Dæmons (SD) and the File Dæmons (FD). Due to this modular design, Bareos is scalable—from single computer systems (where all components run on one machine) to large infrastructures with hundreds of computers (even in different geographies).

Graphics: Mesa 19.2's Feature Freeze and Display Stream Compression (DSC) for AMD Navi

  • Mesa 19.2's Feature Freeze / Release Candidate Process Beginning Tomorrow

    Mesa 19.2 was supposed to be branched marking its feature freeze two weeks ago on 6 August along with the issuing of the first release candidate. That milestone has yet to be crossed but should happen tomorrow. Mesa 19.2 development dragged on for the extra two weeks to allow some extra features to land. Those extra features were metrics/counters support for Intel Iris Gallium3D, CCS_E modifier support, and slice/sub-slice hashing optimizations for Intel -- a big performance win. Now that those blockers have landed, the release process is expected to get underway on Tuesday.

  • Display Stream Compression (DSC) for AMD Navi
    This patchset enables Display Stream Compression (DSC) on DP 
    connectors on Navi ASICs, both SST and DSC.
    
    8k60 and 4k144 support requires ODM combine, an AMD internal
    feature that may be a bit buggy right now.
    
    Patches 1 through 5 enable DSC for SST. Most of the work was
    already done in the Navi promotion patches; this just hooks
    it up to the atomic interface. The first two reverts are of temporary
    changes to block off DSC. The third is of a commit that was
    accidentally promoted twice. The fourth and last revert fixes a 
    potential issue with ODM combine.
    
    Patches 6 and 7 are fixes for bugs that would be exposed by 
    MST DSC. One fix is with the MST code and the other in the DSC code.
    
    Patches 8, 9, and 10 are small DRM changes required for DSC MST:
    FEC, a new bit in the standard; some export definitions; and
    a previously uninitialized variable.
    
    Patches 11 through 14 are the DSC MST policy itself. This includes
    the code for detecting and validating DSC capabilities, enabling
    DSC over a link, computing the fair DSC configurations for
    multiple DSC displays, and adding to atomic state crtcs that might 
    need reprogramming due to DSC.
    
  • AMD Posts Navi Display Stream Compression Support For Linux

    One of the kernel-side features not yet in place for AMD's newest Navi graphics processors on Linux has been Display Stream Compression support but that is being squared away with a new patch series. Fourteen patches posted today adding more than six hundred lines of code to the AMDGPU Linux kernel driver enable Display Stream Compression support for DisplayPort connectors on Navi GPUs. VESA's Display Stream Compression is for low-latency lossless compression performance for power-savings and higher resolution/refresh-rates based on bandwidth and enabling the likes of DisplayPort Multi-Stream Transport (MST) technology.

KMyMoney 5.0.6 released

The KMyMoney development team today announces the immediate availability of version 5.0.6 of its open source Personal Finance Manager. Another maintenance release is ready: KMyMoney 5.0.6 comes with some important bugfixes. As usual, problems have been reported by our users and the development team fixed some of them in the meantime. The result of this effort is the brand new KMyMoney 5.0.6 release. Despite even more testing we understand that some bugs may have slipped past our best efforts. If you find one of them, please forgive us, and be sure to report it, either to the mailing list or on bugs.kde.org. Read more
