  • LibreOffice Qt5 Integration Sees Further Improvements

    The past year LibreOffice has sported a Qt5 interface plug-in for better integration with Qt-based environments like a better "KDE 5" experience. In recent days has been more improvements to this Qt5 integration.

    Hitting the LibreOffice Git tree over the past week has been initial a11y support (accessibility) while landing today was the initial Qt5 clipboard support.

  • Looking forward to Krita 4.2!

    Everyone is hard at work, and what will become Krita 4.2 is taking shape already. Today we’re presenting a preview of Krita 4.2. It’s not complete yet, and there ARE bugs. More than in the stable release (we’ll be doing a 4.1.4 after all next week to clear up some more bugs…), and some might make you lose work.

  • Games 3.30: Features Overload

    With a new version of GNOME always comes a new version of Games, and this new version comes packed with new features, bug fixes and developer experience improvements.

Krita 4.2 Will Be Another Step Up

  • Krita 4.2 Will Be Another Step Up For Open-Source Digital Painting

    The KDE/Qt-aligned Krita open-source digital painting program will soon see its 4.2 feature release that is bringing with it many new features.

    Some of the features already added into the experimental Krita 4.2 are improvements to masks and selections, gamut masks, performance improvements, colored assistants, an improved move tool, a smoother user-interface, and around 200 bug fixes.

GNOME Development Leftovers

  • Nightly GNOME Apps and New Adwaita GTK Theme Run Through
    In this video, we are quickly looking at Nightly GNOME Apps and a sneak peek at New Adwaita GTK Theme.
  • Emmanuele Bassi: And I’m home
    Of course I couldn’t stay home playing video games, recording podcasts, and building gunplas forever, and so I had to figure out where to go to work next, as I do enjoy being able to have a roof above my head, as well as buying food and stuff. By a crazy random happenstance, the GNOME Foundation announced that, thanks to a generous anonymous donation, it would start hiring staff, and that one of the open positions was for a GTK developer. I decided to apply, as, let’s be honest, it’s basically the dream job for me. I’ve been contributing to GNOME components for about 15 years, and to GTK for 12; and while I’ve been paid to contribute to some GNOME-related projects over the years, it was always as part of non-GNOME related work. The hiring process was really thorough, but in the end I managed to land the most amazing job I could possibly hope for.

    GNOME 3.31.3 is out, and this will be the last snapshot of 2018. Note that this is development code meant for testing and hacking purposes. For a list of changes, go here, and the source packages are here.
  • Firmware Attestation
    When fwupd writes firmware to devices, it often writes it, then does a verify pass. This is to read back the firmware to check that it was written correctly. For some devices we can do one better, and read the firmware hash and compare it against a previously cached value, or match it against the version published by the LVFS. This means we can detect some unintentional corruption or malicious firmware running on devices, on the assumption that the bad firmware isn’t just faking the requested checksum. Still, better than nothing. Any processor better than the most basic PIC or Arduino (e.g. even a tiny $5 ARM core) is capable of doing public/private key firmware signing. This would use standard crypto using X.509 keys or GPG to ensure the device only runs signed firmware. This protects against both accidental bitflips and also naughty behaviour, and is unofficial industry recommended practice for firmware updates. Older generations of the Logitech Unifying hardware were unsigned, and this made the MouseJack hack almost trivial to deploy on an unmodified dongle. Newer Unifying hardware requires a firmware image signed by Logitech, which makes deploying unofficial or modified firmware almost impossible.

  • About ncurses Colors
    These colors go back to CGA, IBM's Color/Graphics Adapter from the earlier PC-compatible computers. This was a step up from the plain monochrome displays; as the name implies, monochrome could display only black or white. CGA could display a limited range of colors. CGA supports mixing red (R), green (G) and blue (B) colors. In its simplest form, RGB is either "on" or "off". In this case, you can mix the RGB colors in 2x2x2=8 ways. Table 1 shows the binary and decimal representations of RGB.

Mozilla: Rust and WebAssembly, WebRender, MDN Changelog for November 2018, Things Gateway and Firefox 65 Beta 6 Testday

  • Rust and WebAssembly in 2019
    Compiling Rust to WebAssembly should be the best choice for fast, reliable code for the Web. Additionally, the same way that Rust integrates with C calling conventions and libraries on native targets, Rust should also integrate with JavaScript and HTML5 on the Web. These are the Rust and WebAssembly domain working group’s core values. In 2018, we made it possible to surgically replace performance-sensitive JavaScript with Rust-generated WebAssembly.
  • rust for cortex-m7 baremetal
  • WebRender newsletter #33
    Yes indeed. In order for picture caching to work across displaylists we must be able to detect what did not change after a new displaylist arrives. The interning mechanism introduced by Glenn in #3075 gives us this ability in addition to other goodies such as de-duplication of interned resources and less CPU-GPU data transfer.
  • MDN Changelog for November 2018
    Potato London started work on this shortly after one-time payments launched. We kicked it off with a design meeting where we determined the features that could be delivered in 4 weeks. Potato and MDN worked closely to remove blockers, review code (in over 25 pull requests), and get it into the staging environment for testing. Thanks to everyone’s hard work, we launched a high-quality feature on schedule. We’ve learned a lot from these payment experiments, and we’ll continue to find ways to maintain MDN’s growth in 2019.

Fedora Developers Are Trying To Figure Out The Best Linux I/O Scheduler, Fedora 29 Review and Fedora Program Management

ARM's Work in Linux (Kernel)

  • Energy Model Management Framework Queued For Linux 4.21
    A new framework queued for introduction with the Linux 4.21 kernel is the ARM-developed Energy Model Management Framework. With different hardware and drivers exposing the processor/system energy consumption in different manners, the Energy Model Management Framework tries to provide a standardized way of accessing the power values for each performance domain in a system. This can help kernel drivers/schedulers and other code that could make smarter decisions based upon current energy use be able to do so via this standardized framework for acquiring the power information on capable systems.
  • ARM's AArch64 Adding Pointer Authentication Support To The Linux 4.21 Kernel
    The 64-bit ARM architecture code (a.k.a ARM64 / AArch64) with the Linux 4.21 kernel is seeing pointer authentication added as a new security feature. Pointer authentication can be supported by ARMv8.3 hardware and newer to allow for signing and authenticating of pointers against secret keys. The purpose of this pointer authentication is to mitigate ROP attacks and other potential buffer-overrun-style attacks. This ARM64_PTR_AUTH functionality will enable pointer authentication for all user-space processes and the presence of supported hardware is determined at run-time. ARM developers have been working on the plumbing for this Linux kernel support for it the past year.
