  • Clarissa Borges: Which library is the GNOME UI extending from?

    About two weeks ago I did some research and learned about some libraries to choose one to extend from to use on my GSoC GNOME UI library project, and it turned out to be a very interesting topic that I’d like to share and take the opportunity to talk about how’s the project going, as it’s been a while since I don’t blog :P In case you don’t know what my project is about, I recommend you to visit my first post where I provide an explanation of the project goals.

  • KDE Plasma 5.20 Pre-Beta Run Through

    In this video, we are looking at KDE Plasma 5.20 Pre-Beta. Enjoy!

  • DebConf6 (20200804-debconf6)

    DebConf6 was my 4th DebConf and took place in Oaxtepec, Mexico. I'm a bit exhausted right now which is probably quite fitting to write something about DebConf6... many things in life are a question of perception, so I will mention the waterfall and the big swirl and the band playing with the fireworks during the conference dinner, the joy that we finally could use the local fiber network (after asking for months) just after discovering that the 6h shopping tour forgot to bring the essential pig tail connectors to connect the wireless antennas to the cards, which we needed to provide network to the rooms where the talks would take place. DebConf6 was the first DebConf with live streaming using dvswitch (written by Ben Hutchings and removed from unstable in 2015 as the world had moved to voctomix, which is yet another story to be told eventually). The first years (so DebConf6 and some) the videoteam focussed on getting the post processing done and the videos released, and streaming was optional, even though it was an exciting new feature and we still managed to stream mostly all we recorded and sometimes more...

  • DSLR Motion Capture with Raspberry Pi and OpenCV
  • mOLOID is a pet like no other

    As a part of their masters program at the University of Stuttgart, Jan Ingo Haller and Lorin Samija created a robotic pet that moves in a manner that may not be immediately evident. With the internals obscured by a cloth covering, the moving OLOID, or mOLOID, seems to roll from one vague lobe section to another like some sort of claymation creature. The mOLOID’s unique locomotion is due to an internal “oloid” structure, an arrangement of two circles at 90°. Two servos move weights around the perimeter of each circle to vary its center of gravity, causing it to flop back and forth.

  • How to speed up the Rust compiler some more in 2020

    First up is a process change: I have started doing weekly performance triage. Each Tuesday I have been looking at the performance results of all the PRs merged in the past week. For each PR that has regressed or improved performance by a non-negligible amount, I add a comment to the PR with a link to the measurements. I also gather these results into a weekly report, which is mentioned in This Week in Rust, and also looked at in the weekly compiler team meeting. The goal of this is to ensure that regressions are caught quickly and appropriate action is taken, and to raise awareness of performance issues in general. It takes me about 45 minutes each time. The instructions are written in such a way that anyone can do it, though it will take a bit of practice for newcomers to become comfortable with the process. I have started sharing the task around, with Mark Rousskov doing the most recent triage. This process change was inspired by the “Regressions prevented” section of an excellent blost post from Nikita Popov (a.k.a. nikic), about the work they have been doing to improve the speed of LLVM. (The process also takes some ideas from the Firefox Nightly crash triage that I set up a few years ago when I was leading Project Uptime.)

  • Data@Mozilla: Experimental integration Glean with Unity applications

    You might notice Firefox Reality PC Preview has been released in HTC’s Viveport store. That is a VR web browser that provides 2D overlay browsing alongside immersive content and supports web-based immersive experiences for PC-connected VR headsets. In order to easily deploy our product into the Viveport store, we take advantage of Unity to help make our application launcher. Also because of that, it brings us another challenge about how to use Mozilla’s existing telemetry system. As we know, Glean SDK has provided language bindings for different programming language requirements that include Kotlin, Swift, and Python. However, when we are talking about supporting applications that use Unity as their development toolkit, there are no existing bindings available to help us achieve it. Unity allows users using a Python interpreter to embed Python scripts in a Unity project; however, due to Unity’s technology being based on the Mono framework, that is not the same as our familiar Python runtime for running Python scripts. So, the alternative way we need to find out is how to run Python on .Net Framework or exactly on Mono framework. If we are discussing possible approaches to run Python script in the main process, using IronPython is the only solution. However, it is only available for Python 2.7, and the Glean SDK Python language binding needs Python 3.6. Hence, we start our plans to develop a new Glean binding for C#.

  • Podcast: CLUECON SPECIAL FEATURE – OrecX not only delivers top shelf stereo recording, but delivers a huge ecosystem of add on technology that may already provide the capability you want to use

    Bruce and OrecX have also been attending the ClueCON Conference from the beginning. The founders of OrecX are open source recording pioneers, launching the Oreka GPL in 2005 (used today by millions in over 190 countries).

The 10 Best KDE Plasma Widgets for KDE Desktop Environment

If you were looking for the best KDE Plasma widgets for your Linux desktop, then you are in the right place. There is much debate about the fact of who implemented the widget feature first on a computer GUI. But nobody can deny that the widgets have brought a new era in the modern user interface. Most of the people rely on beautiful widgets for performing different tasks without opening the main instance of the program. Although Windows ditched their native desktop widgets feature with their Windows 8 for the sake of the live tiles. Linux still has a great library of widgets that are being maintained by the developer community. Read more

Games: Cursed Gem, Last Epoch, Jagged Alliance 2 and More

  • Cursed Gem is a pretty charming and amusing challenging platformer out now

    I have to admit, Cursed Gem is quite a nice surprise. Throwing in a little comedy into a challenging pixel-art platformer.

  • Action RPG 'Last Epoch' laughs at your free time with the biggest update ever

    Free time be damned, it's time to jump back into Last Epoch for another dozen hours or so because Eleventh Hour Games clearly don't want me to sleep tonight. On August 4 they released update 0.7.9, which they said was the "BIGGEST update in Last Epoch history". What's the big fuss about with this update? It splits off The Monolith of Fate end game into its own zone, with several islands each containing "a Timeline representing a reality that never was". Confused? Well, Last Epoch is an action RPG that involves a wee bit of time travel. As you progress and conquer timelines, you get all sorts of fancy rewards and you they're repeatable with different layouts. Sounds awesome.

  • Minesweeper but it's a rogue-lite with tons of features - DemonCrawl is out for Linux PC

    Oh no, I think DemonCrawl might just end up being my next 100 hour game and it's now available for Linux PC. Released originally in November 2019, the developer decided to support Linux to ensure people can get the best experience rather than relying on the Proton compatibility layer. Two weeks after announcing it and the Linux version has been released.

  • Jagged Alliance 2 game engine 'Stracciatella' has a big new release

    The community working to keep the classic Jagged Alliance 2 alive with the Stracciatella game engine have put out their first release in a few years. With the Stracciatella project their aim is to provide good cross-platform support, improve stability, fix bugs and provide a stable platform for mod development. It's a noble aim, especially when it's an old game long left behind by the original teams and in this case the original developer and publisher no longer even exist.

  • Master of Orion inspired open source 4x strategy FreeOrion has a new release

    Inspired originally by Master of Orion, the free and open source FreeOrion project has a brand new release. For the FreeOrion, this was a reasonably quick release considering they had another release back in February and they don't usually update too often. For a good reason this time though, as they've managed to do a major tech move from Python 2 to 3 to enable FreeOrion to stay up to date with modern code. That wasn't the only big change though.

  • Take an emotional trip through the mind in Into A Dream out now

    Into A Dream is a brand new release from indie developer Filipe F. Thomaz, telling a tale about diving into the mind of someone diagnosed with severe depression. You're quite literally exploring their mind too, using the power of medical science. You will be travelling through the mind of Luke Williams, as their last hope before "fading away". You need to find the events that led to their darkened mind, meeting family and friends (well, memories of them anyway) while finding a way to "trick him into letting you access his darker dreams and unveil the emotional, powerful and heartbreaking journey of his life".
