KDE in Slackware, Cutelyst 1.4.0 Ready

Filed under
  • KDE 5_17.02 for Slackware-current is available

    I am happy to announce my February 2017 release of the ‘ktown’ packages: KDE 5_17.02. What you get in this new release is: KDE Frameworks 5.31.0, Plasma 5.9.2 and Applications 16.12.2. All built on top of Qt 5.7.1.
    Soon, I will compile this version of Plasma 5 on Slackware 14.2 (only 64bit) as well, but I gave priority last few days to the new LibreOffice packages and a new PLASMA5 Live image. The packages that I am releasing today are for Slackware-current only (both 32bit and 64bit). As stated in my previous post, I will no longer be releasing Plasma 5 packages for 32bit Slackware 14.2.

  • New Slackware PLASMA5 Live ISO (with Plasma 5.9)

    To conclude this week’s batch of updates in my repositories I have re-generated the ISO for PLASMA5 Slackware Live Edition – it is based on liveslak and using Slackware-current dated “Mon Feb 13 06:21:22 UTC 2017“.

    If you already use PLASMA5 Live on a USB stick that you do not want to re-format, you should use the “-r” parameter to the “” script. The “-r” or refresh parameter allows you to refresh the liveslak files on your USB stick without touching your custom content.

  • Cutelyst 1.4.0 released, C100K ready.

    Thanks to the last batch of improvements and with the great help of jemalloc, cutelyst-wsgi can do 100k request per second using a single thread/process on my i5 CPU. Without the use of jemalloc the rate was around 85k req/s.

    This together with the EPoll event loop can really scale your web application, initially I thought that the option to replace the default glib (on Unix) event loop of Qt had no gain, but after increasing the connection number it handle them a lot better. With 256 connections the request per second using glib event loop get’s to 65k req/s while the EPoll one stays at 90k req/s a lot closer to the number when only 32 connections is tested.

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.
