  • Introducing plasma timekeeper – an applet measuring your activity

    Have you ever wondered how much time do you spend reading emails, browsing on internet or hacking? I have! I started thinking about monitoring my activity. Reason for this was that I work from home, where I’m alone and nobody is behind my back watching what I’m actually doing. So I came with an idea to write a simple applet which tracks the time you spent in a certain application by just checking your currently active window (application). The functionality is pretty simple, you switch focus to a window where you do something, the applet starts measuring the time and update it in some interval until you switch to another window and so on. It may not be accurate in case you will be cheating, e.g. you open a video player and start watching a movie while you switch focus to another app to avoid monitoring time spent in the video player. Given this, the purpose of the applet is pretty obvious, it should be just for you, for your personal usage when you have no reason for cheating, because you are interested in these statistics.

  • How much is 1 TeV?

    We are about half way trough this WTL Sprint @CERN, so I’ve decided to post something about my experience. Actually in this post I do not want to talk about our work, probably I’ll dedicate another article to it at the end of this week, but about one of the talks we had the opportunity to listen. On monday Ezio Todesco (CERN) gave us a talk about CERN history and magnets in LHC.

  • Under the Weather

    The first is weather! It was previously announced that Plasma 5.6 will be seeing the return of the weather widget. Lots of design work and planning has been done for it and while not everything we discussed will make it in for this release I do happily get to show off our new Breeze weather icons;

  • digiKam Recipes 4.11.1 Released

    A new release of digiKam Recipes is ready for your reading pleasure. This version introduces the Basic Concepts Explained appendix that covers key terms and concepts used in digiKam. Currently, the appendix contains information about chroma subsampling, cor (bit) depth, hue, saturation, brightness, and vibrance. I plan to gradually expand the appendix with time.

  • conf.KDE.in 2016, Jaipur

    Thank you KDE India for inviting us to share our experience with 250+ budding developers and spreading the knowledge we have acquired during our projects. It was beyond just a meetup, we made many new friends and also learnt a lot from each other. I would also like to thank LNMIIT for hosting such an amazing conference and for the flawless hospitality.

  • Hug the LHC

    We passed through retina based authentication, elevators up to 80 meters high, and at the end of the cave there it was: the CMS gigantic machine.

    After the hardware stuff under the ground we saw the data center (#1 level of triggering) and the control room, where we found Plasma 4.2 running on those machines!

  • That’s over 200 Petabytes!

    Today, on the third day of the WikiToLearn Sprint at CERN hosted by KDE e.V., we had the pleasure of listening to an interesting and inspiring lecture by Professor Pere Mato Villa, who talked about Computing for Data Processing and Analysis at CERN. In approximately one hour, we were enlightened on the techniques and methods in use in the various LHC experiments to acquire and process raw data from detectors. He also explained the massive extent of the IT infrastructure that’s needed to host all the data: currently all the LHC experiments rely on distributed computing resources, accounting for roughly 350,000 CPU cores, and 400 PB of disk and tape storage combined. That’s a huge one!

  • Workaround for trouble with updating akonadi tables
  • C++ and KDE in CERN

    Some time ago, I saw that CERN people had their own clang tree with a few addons, most notable one being the C++ REPL (C++ interpreter) called cling.

    Now we had a presentation by Pere Mato from CERN who talked about their ROOT data analysis framework. It seems like a really nice and powerful piece of software.

    The software is around 50 million lines of code, mostly C++. Some of it is python, but it is only used for quick-and-dirty testing of new ideas.

  • Wiki Reorganisation

    A group of us at the CERN-based cross-team sprint are attempting to tame the wilderness of the KDE wikis – at least, TechBase and Community.

    A little bit of history is needed here. Originally, TechBase was the only wiki, and it quickly became a dumping ground for pretty much everything. At some point, the other two wikis (Community and UserBase) were created so we could separate things out a bit, and people wanting tutorials for how to create Plasmoids, for example, wouldn’t be overwhelmed with meeting notes from the Plasma team.

Exp-run for KDE4 on FreeBSD

Filed under
KDE
BSD

There’s an exp-run going on for KDE4 on FreeBSD right now. That means that the official package-building machines are grinding through the entire ports tree to see what happens. This is part of the regular procedure for big updates — and this is a big one.

While KDE4 as a desktop — with Plasma shell 4 and the old collection of KDE modules like PIM, etc. — is not getting a lot of upstream releases, it does get some updates, and some applications release new versions. This is one reason to continue to update the packages.

  • Selecting text in the Calligra-powered Okular plugin for ODT, DOC, DOCX & WPD

    Traveling 8+ hours on the train all the way through Germany to Geneva in Switzerland, where CERN is located (its area spreading across the border to France actually), the place of the WikiToLearn-Plasma-VDG-TechbaseOverhaul meeting, was also a good chance to first spend some time again on a sprint-unrelated, but still KDE-related item, which is adding support for text selection to the Calligra-powered Okular plugin for text documents.

  • We are digging a hole

    Now, jokes apart, we really are digging a hole. In the academic system. In the spread of knowledge. We are working on a project which will change the academic career of a really high number of students, I’m sure of this. The guys are now at CERN, in Geneve, working hard on the this project. The sprint started this morning, and I am sad about my being at home for many reasons: they will work on topics we have talked on Telegram, they will visit the LHC, Large Hadron Collider, (and you can imagine what means, for a physics student, have the possibility to get there and visiting it) and I am at home. Obviously, I will partecipate at some debates thanks to internet, through livestreams which will be hosted the next days. I just want to whish the guys have good times there, work hard and improve this project.

  • TechBase Wiki Overhaul at CERN

    KDE’s techbase wiki, “the primary place for technical information about KDE targeted at developers, ISVs and sysadmins”, has been gone lost a little during the transition of KDE software to KF5 and Plasma5.

  • On my way to CERN for a KDE Sprint

    Time has been crazy lately for me. So crazy that, I haven’t even managed to blog about many things that I wish I’ve had. And because time is till crazy (haven’t finished packing and taking off in a few hours), I’m blogging about this trip in the last 100 meters.

KDE Makes the Desktop Practical Again

Filed under
KDE

Before the KDE 4.1 release in 2008, Aaron Seigo announced the end of desktop icons. He was being provocative, because what he was really announcing was the end of being restricted to a single icon set. Instead, KDE Plasma began supporting multiple desktops, and with them several ways to swap sets of icons in and out. These changes have received little publicity, but they are ideal for quickly customizing a desktop for a specialized task.

You do not have to use these features. However, if you choose to explore them, you can apply them not only to the main desktop, but also to any activities, or even any virtual workspaces, so long as you first select from the main menu System Settings > Workspace Behavior > Virtual Desktop > Different Widgets for each desktop. It's all a matter of which combination of customizations you prefer: a default desktop, folder views, multiple desktop folders, or a single desktop folder with filters.

  • After the hype: Where containers make sense for IT organizations
    Container software and its related technologies are on fire, winning the hearts and minds of thousands of developers and catching the attention of hundreds of enterprises, as evidenced by the huge number of attendees at this week’s DockerCon 2016 event. The big tech companies are going all in. Google, IBM, Microsoft and many others were out in full force at DockerCon, scrambling to demonstrate how they’re investing in and supporting containers. Recent surveys indicate that container adoption is surging, with legions of users reporting they’re ready to take the next step and move from testing to production. Such is the popularity of containers that SiliconANGLE founder and theCUBE host John Furrier was prompted to proclaim that, thanks to containers, “DevOps is now mainstream.” That will change the game for those who invest in containers while causing “a world of hurt” for those who have yet to adapt, Furrier said.

Industrial SBC builds on Raspberry Pi Compute Module

On Kickstarter, a “MyPi” industrial SBC using the RPi Compute Module offers a mini-PCIe slot, serial port, wide-range power, and modular expansion. You might wonder why in 2016 someone would introduce a sandwich-style single board computer built around the aging, ARM11 based COM version of the original Raspberry Pi, the Raspberry Pi Compute Module. First off, there are still plenty of industrial applications that don’t need much CPU horsepower, and second, the Compute Module is still the only COM based on Raspberry Pi hardware, although the cheaper, somewhat COM-like Raspberry Pi Zero, which has the same 700MHz processor, comes close.
