Recreating the PCLinuxOS Full Monty with KDE Plasma Activities

Filed under
KDE
PCLOS

When I recently wrote about the new PCLinuxOS release, I was a bit disappointed to find that the Full Monty version had been laid to rest. I'm sure there were a lot of good reasons for this decision, and I have no quarrel with it. But it still made me a bit sad, because I have always kept the Full Monty on at least one of my systems (it is currently on my Acer All-In-One desktop), and I often showed it to people who were curious about Linux, as an example of its breadth, depth and flexibility.

So I decided that it might be a useful exercise for me to try to create the equivalent of the Full Monty desktop starting from the latest PCLinuxOS KDE5 distribution. There are two major features which distinguish the Full Monty desktop - it had six virtual desktops, each of which was dedicated to a specific use, and it had lots and lots and lots of packages installed. The desktops looked like this:

  • Best practices for guiding new coders

    As the new year progresses, many free and open source projects are turning their attention to various formalized mentoring programs, such as Mozilla's Winter of Security, Outreachy, and (the program with my favorite name) the X.Org Endless Vacation of Code. Patterned after the success of Google's Summer of Code, these programs give many new programmers a chance to gain firsthand experience working within successful FLOSS (Free/Libre Open Source Software) projects and the projects themselves access to fresh talent.

  • Developing an nrf51822 based embedded device with Qt Creator and Debian

    I'm currently developing an nRF51822-based embedded device. Being one the Qt/Qt Creator maintainers in Debian I would of course try to use it for the development. Turns out it works pretty good... with some caveats.

    With Qt 5.7 and 5.8 released we have a completely new baseline for Qt 5 based applications and devices. In this blog, I want to provide a roadmap update on what we are currently working on in the Qt R&D and what the future directions are.

  • Qt's Roadmap For 2017: Graphics, An Exciting Qt 5.9/5.10

    Tuukka Turunen of The Qt Company has shared some of the project's goals for the 2017 calendar year in delivering Qt 5.9 and Qt 5.10 along with more point releases.

    Qt developers hope to make 2017 exciting by shipping Qt 5.9 in May and their hope is to ship Qt 5.10 this November.

  • Fedora 25 KDE: disappointing experience

    Fedora is not a frequent guest on the review deck of Linux notes from DarkDuck blog. The most recent review was of Fedora 22 back in July 2015. That was a review of the GNOME version, the most native for Fedora.

    You are probably aware of the tight link between the GNOME project and RedHat, the Fedora Project main sponsor.

  • Plasma in a Snap?

    Shortly before FOSDEM, Aleix Pol asked if I had ever put Plasma in a Snap. While I was a bit perplexed by the notion itself, I also found this a rather interesting idea.

    So, the past couple of weeks I spent a bit of time here and there on trying to see if it is possible.

  • QStringView Diaries: Advances in QStringLiteral

    This is the first in a series of blog posts on QStringView, the std::u16string_view equivalent for Qt. You can read about QStringView in my original post to the Qt development mailing-list, follow its status by tracking the “qstringview” topic on Gerrit and learn about string views in general in Marshall Clow’s CppCon 2015 talk, aptly named “string_view”.

  • Making Movies with QML

    One of the interesting things about working with Qt is seeing all the unexpected ways our users use the APIs we create. Last year I got a bug report requesting an API to set a custom frame rate for QML animations when using QQuickRenderControl. The reason was that the user was using QQuickRenderControl as an engine to render video output from Qt Quick, and if your target was say 24 frames per second, the animations were not smooth because of how the default animation driver behaves. So inspired by this use case I decided to take a stab at creating such an example myself.

Filed under
KDE

The latest updates for KDE's Plasma, Applications and Frameworks series are now available to all Chakra users.

Included with this update, is an update of the ncurses, readline and gnutls related group of packages, as well as many other important updates in our core repository. Be aware that during this update, your screen might turn black. If that is the case and it does not automatically restore after some time, then please switch to tty3 with Ctrl+Alt+F3 and then switch back to the Plasma session with Ctrl+Alt+F7. If that does not work, please give enough time for the upgrade to complete before shutting down. You can check your cpu usage using 'top' after logging in within tty3. You can reboot within tty3 using 'shutdown --reboot'.

The State of Plasma

Filed under
KDE

Over the years, my experience with KDE can best be described as a rollercoaster – on ice, with rocket thrusters. KDE3.5 was a great release, followed by a somewhat mellow, emotionally curbed KDE4, which took years blossoming, and then when it finally gained solid form, it was replaced with KDE5, or rather, Plasma 5.

Since 2014, Plasma has kept me entertained and disappointed in equal measures. At some point, I had it crowned my favorite desktop, and then it went downhill steeply, fast, struggling to recover. Not helping was the slew of bugs and regressions across the distro space, which exacerbated the quality of Plasma and what it could show the world. Today, I would like to explore Plasma from a different angle. Not from the user perspective, but usability perspective. AKA Everything What Plasma Does. After me.

KDE in Slackware, Cutelyst 1.4.0 Ready

Filed under

Slack
  • 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 1.1.6.2 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 “iso2usb.sh” 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.

    KDE developer Albert Astals Cid announced that the release date of the upcoming KDE Applications 17.04 open-source software suite for KDE Plasma desktop environments, along with the final release schedule.

    We were just wondering when KDE Applications 17.04 will be released when the current KDE Applications 16.02 series received its second maintenance update, and we were right to believe at the point in time that the final release is coming in April, and, according to the release schedule, it looks like KDE Applications 17.04 lands April 20, 2017.

  • KDE Applications 17.04 To Be Released 20 April

    The release schedule for the upcoming KDE Applications 17.04 has been firmed up.

    The KDE Applications 17.04 release is scheduled to happen on 20 April. For that to happen, the planned dependency freeze is 16 March, the beta release on 23 March, KDE applications 17.04 Release Candidate on 6 April, and prepping for the actual 17.04 release beginning on 13 April.
