SDL Now Disables Mir By Default In Favor Of Wayland Compatibility

Friday 23rd of February 2018 07:15:57 PM
With Mir focusing on Wayland compatibility now, toolkits and other software making direct use of Mir's APIs can begin making use of any existing Wayland back-end instead. GTK4 drops the Mir back-end since the same can be achieved with the Wayland compatibility and now SDL is now making a similar move...

lkml: remove eight obsolete architectures

In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point. Read more

If you hitch a ride with a scorpion… (Coverity)

I haven’t seen a blog post or notice about this, but according to the Twitters, Coverity has stopped supporting online scanning for open source projects. Is anybody shocked by this? Anybody? [...] Not sure what the story is with Coverity, but it probably has something to do with 1) they haven’t been able to monetize the service the way they hoped, or 2) they’ve been able to monetize the service and don’t fancy spending the money anymore or 3) they’ve pivoted entirely and just aren’t doing the scanning thing. Not sure which, don’t really care — the end result is the same. Open source projects that have come to depend on this now have to scramble to replace the service. [...] I’m not going to go all RMS, but the only way to prevent this is to have open tools and services. And pay for them. Read more

Easily Fund Open Source Projects With These Platforms

Financial support is one of the many ways to help Linux and Open Source community. This is why you see “Donate” option on the websites of most open source projects. While the big corporations have the necessary funding and resources, most open source projects are developed by individuals in their spare time. However, it does require one’s efforts, time and probably includes some overhead costs too. Monetary supports surely help drive the project development. If you would like to support open source projects financially, let me show you some platforms dedicated to open source and/or Linux. Read more

  • First blog & KDE Connect media control improvements
    I've started working on KDE Connect last November. My first big features were released yesterday in KDE Connect 1.8 for Android, so cause for celebration and a blog post! My first big feature is media notifications. KDE Connect has, since it's inception, allowed you to remotely control your music and video's. Now you can also do this with a notification, like all Android music apps do! So next time a bad song comes up, you don't need to switch to the KDE Connect app. Just click next on the notification without closing you current app. And just in case you don't like notifications popping up, there's an option to disable it.
