KDE: Astronomy on KDE, MQTT/GSoC, Konversation Tip

Filed under
  • Astronomy on KDE

    I recently switched to KDE and Plasma as my main desktop environment, so I thought I'd start digging into some of the scientific software available on KDE. First up is KStars, the desktop astronomy program.

  • LabPlot's MQTT in the finish line

    Hello everyone. GSoC is coming to its end, so I think that I should give a report about what's been done since the last post, and also make a brief evaluation, summary of the project itself.

    As I've written in my last post, the main focus was on improving the quality of the code, cleaning, optimizing and properly documenting it. And also making it more comestible for other developers.

    The next step was searching for bugs and then fixing them. In order to do this properly, I implemented a unit test for the main MQTT related features. This proved to be useful since it helped discover several hidden bugs and errors which were all corrected. The main features, that tests were developed for, are: checking if a topic contains another one, checking if two topics are "common topics" (meaning they only differ at only one level, and are the same size), managing messages, subscribing&unsubscribing.

  • PSA: Use SASL in konversation

    You probably have seen that Freenode has been getting lots of spam lately.

    To protect against that some channels have activated a flag that only allows authenticated users to enter the channel.

    If you're using the regular "nickserv" authentication way as I was doing, the authentication happens in parallel to entering the channels and you'll probably be rejected from joining some.

KDE is adding Matrix to its instant messaging infrastructure

KDE has been looking for a better way of chatting and live-sharing information for several years now. IRC has been a good solution for a long time, but it has centralized servers KDE cannot control. It is also insecure and lacks features users have come to expect from more modern IM services. Other alternatives, such as Telegram, Slack and Discord, although feature-rich, are centralized and built around closed-source technologies and offer even less control than IRC. This flies in the face of KDE's principles that require we use and support technologies based on Free software. However, our search for a better solution has finally come to an end: as of today we are officially using Matrix for collaboration within KDE! Matrix is an open protocol and network for decentralised communication, backed by an open standard and open source reference implementations for servers, clients, client SDKs, bridges, bots and more. It provides all the features you’d expect from a modern chat system: infinite scrollback, file transfer, typing notifications, read receipts, presence, search, push notifications, stickers, VoIP calling and conferencing, etc. It even provides end-to-end encryption (based on Signal’s double ratchet algorithm) for when you want some privacy.

Canonical Is Planning Some Awesome New Content For The Snap Store

There I was, thoughtfully drafting an article titled "3 Things Canonical Can Do To Improve The Snap Ecosystem," when I jumped on the phone with Evan Dandrea, an Engineering Manager who just so happens to be responsible for the Snapcraft ecosystem at Canonical. As it turns out, that headline will need a slight edit. One less number. That's because I've just learned Canonical has some ambitious plans for the future of the Snap Store. Read more

Extensive Benchmarks Looking At AMD Znver1 GCC 9 Performance, EPYC Compiler Tuning

With the GCC 9 compiler due to be officially released as stable in the next month or two, we've been running benchmarks of this near-final state to the GNU Compiler Collection on a diverse range of processors. In recent weeks that has included extensive compiler benchmarks on a dozen x86_64 systems, POWER9 compiler testing on the Talos II, and also the AArch64 compiler performance on recent releases of GCC and LLVM Clang. In this latest installment of our GCC 9 compiler benchmarking is an extensive look at the AMD EPYC Znver1 performance on various releases of the GCC compiler as well as looking at various optimization levels under this new compiler on the Znver1 processor.
