  • Mariam Fahmy GSoC’21 Week 2, 3 and 4: Finalizing learn decimals activities

    In this activity, a decimal number is displayed. the bar with the arrow represents a full unit, and each square in it represents one tenth of this unit, the kid has to drag the arrow to select a part of the bar, and drop the selected part into the empty area so that the number of dropped bars corresponds to the displayed decimal number.

    For every dropped bar, all bars are organized after 1 second from the drop action such that the kid can see the reorganization of bars, as a result we add a place for a 6th bar to have at most 5 full bars.

    The activity provides instruction tutorials on how to play with it, both vertical and horizontal layout are supported.

  • KDE Documentation & New Job at Nextcloud

    It also means I’m leaving my current part-time job at the KDE e.V. working on the documentation tooling. This was shorter than initially planned (a bit more than one month instead of three), but even though I didn’t finish doing everything I wanted to do, I still did a few things during this short time.

    First, I continued my previous work on, making it possible for the translators to translate the content. For now, only the Kirigami tutorial is translated, but more should be available by simply toggling some switches.

    Another thing I worked on was phasing out This website was created before develop.k.o was created and develop.k.o is nowadays a better place to add the plasma mobile developer documentation, next to the Kirigami and Plasma tutorials. The small bits of user documentation is getting moved to the plasma-mobile website.

    And also made some small improvements to KApiDox. I fixed the sorting of products to always include the KDE Frameworks and KDE PIM on top made the navbar consistent with and a made a few other minor tweaks.

    Aside from that I also made many small patches to the API documentation itself in Ki ri ga mi, KGuiAddons, Plasma Workspace and a few other places.

    I will still be around and you can still ping me on Matrix for documentation tooling related questions Smile

    Thanks a lot to the KDE e.V. for entrusting me with this responsibility. If you want to help supports others and make KDE software better, consider donating to the KDE e.V.. The donation is tax-deductible in Germany (and maybe in other EU countries too).


  • Christian Hergert: GtkSourceView Searching with PCRE2

    Last year I did some work to make GtkSourceView use PCRE2 for syntax highlighting. The primary motivation there was to improve syntax highlighting performance by using PCRE2’s JIT capability.

    However, that left us in an odd place with how GtkSourceSearchContext works for regex-enabled search. It was using GRegex which itself uses PCRE (1). It’s pretty clear that the goal is to completely deprecate GRegex in GLib and it’s days are numbered. In particular, there is a lot we can’t do to control the execution environment and protect against things like stack overflows. Worsening things, PCRE doesn’t appear to be maintained these days.

  • Maximiliano Sandoval: GSoC 2021 and GNOME Design tools

    This Google School of Code, I decided to work with Bilal Elmoussaoui as a mentor, the goal being updating some GNOME design tools to GTK 4, specifically Icon Library and App Icon Preview. Both apps are written in Rust and make use of the gtk-rs bindings for gtk.

Software: Matrix, Ktube, and Monero P2Pool

  • Chat Bubbles on Element and Several Matrix Apps

    This simple comparison wants to help everyone adopt alternative messaging technology, Matrix, with suitable user interface to them. We call Matrix Apps to instant messengers like Element, Fluffy, Nheko, Schildi and Spectral as they are created based upon the said technology. We will start by setting up criteria first that includes chat bubbles, then going through these messengers one by one, and you will see their pictures here along with a little comments from me. I hope you can pick up the messenger with UI you love the most from here.

  • Ktube Media Downloader lets you download YouTube videos easily on Linux

    I always like to tell people about how I have been using Linux as my primary operating system for over ten years. I love Linux, I understand it, it’s free and above all, it fits my workflow in a way Microsoft’s Windows (with all its goodness) probably never will. That also means I love and am a command-line ninja but I also know one thing, a lot of people out there fear and hate the command line.

  • Monero P2Pool V1.0 Is Released

    The latest version of P2Pool, a decentralized Monero mining pool has released. This is the first official release, signaling an invitation for more users to try out the new software.

Better Support & Performance For OpenACC Kernels Is Coming To GCC

While the GNU Compiler Collection has supported OpenACC for a few years now as this parallel programming standard popular with GPUs/accelerators, the current implementation has been found to be inadequate for many real-world HPC workloads leveraging OpenACC. Fortunately, Siemens has been working to improve GCC's OpenACC kernels support. GCC's existing OpenACC kernels construct has been found to be "unable to cope with many language constructs found in real HPC codes which generally leads to very bad performance." Fortunately, improvements are on the way and could potentially be mainlined in time for next year's GCC 12 stable release. Read more

Security Leftovers

  • Database containing 106m Thailand travelers' details leaked • The Register

    A database containing personal information on 106 million international travelers to Thailand was exposed to the public internet this year, a Brit biz claimed this week. Bob Diachenko, head of cybersecurity research at product-comparison website Comparitech, said the Elasticsearch data store contained visitors' full names, passport numbers, arrival dates, visa types, residency status, and more. It was indexed by search engine Censys on August 20, and spotted by Diachenko two days later. There were no credentials in the database, which is said to have held records dating back a decade. “There are many people who would prefer their travel history and residency status not be publicized, so for them there are obvious privacy issues,” wrote Comparitech editor Paul Bischoff on the company’s blog.
