  • Top 12 Python Web Frameworks of 2019 Programmes Should Know
  • Best Free Books to Learn about Scratch

    Scratch is a visual programming language developed by the Lifelong Kindergarten Group at the MIT Media Lab. Scratch teaches programming concepts to kids, offering a stepping stone to more complicated programming languages. Coding includes dragging and dropping various code blocks and linking them together like jigsaw pieces to form logical scripts. While the MIT Media Lab designed this language for 8-16 year-old children, it is used by people of all ages.

    Scratch has received many plaudits as an ideal way to introduce kids to computer programming and computational thinking. It’s a fantastic beginner’s language. Scratch is often used to make games, interactive stories, and animations, but it can be used for any purpose. The language uses event-driven programming with multiple active objects. The language helps students to think creatively, reason logically, and work together. The language is frequently used in schools, libraries, community centres, and museums.

    Scratch is released under an open source license. I recommend 7 free books that really help young people master Scratch. These recommended texts are also open source goodness.

  • Introducing The New Librem Chat

    Social good, freedom personal privacy and security are things you take seriously (and probably think everyone else should, too). And maybe you already know that the Librem Chat is part of Librem One, a suite of privacy-protecting, no-tracking apps and services which aim to make the world a better place.

  • Top Android Apps to Remote Control Your Linux Desktop

    Remote Access/Control software is important for convenience and/or emergency purposes because it enables users to control their computer systems from the convenience of their couch, for example.

    Earlier this year, I covered the 10 best TeamViewer alternatives for Linux so today, let’s turn our attention to smartphones as I introduce you to the best remote control Android apps for Linux.

    [...]

    KDE Connect is a free and open source end-to-end TLS encrypted utility for remotely controlling Linux desktops, sharing files and controlling media players over a Wi-Fi connection. With it, you can share files, URLs, and clipboard content between your computer and any app, read SMS notifications and get call alerts.

  • FOSS Project Spotlight: Bareos, a Cross-Network, Open-Source Backup Solution

    Bareos (Backup Archiving Recovery Open Sourced) is a cross-network, open-source backup solution that preserves, archives and recovers data from all major operating systems. The Bareos project started 2010 as a Bacula fork and is now being developed under the AGPLv3 license.

    The client/server-based backup solution is actually a set of computer programs (Figure 1) that communicate over the network: the Bareos Director (BD), one or more Storage Dæmons (SD) and the File Dæmons (FD). Due to this modular design, Bareos is scalable—from single computer systems (where all components run on one machine) to large infrastructures with hundreds of computers (even in different geographies).

Games: Unity, Super Slap Sisters, Ayo the Clown and Steam News Hub

  • Unity 2020.2 Bringing Some Hefty Performance Optimizations [Ed: Microsoft Mono unfortunately]

    Not only did Unity Software experience a successful IPO last week but they also rolled out the Unity 2020.2 engine into public beta and with that comes some "major speed-ups" for performance.

  • Super Slap Sisters [Ed: Requires WINE]

    These are some great additions that allow for an even wider variety of playstyles, keeping your opponent guessing as to when the best time to strike is. For example, not only can the clutch be used during an attack to throw your opponent off, it can also be a lifesaver just as you’re about to reach the blastzone (knockout boundaries) after getting hit. The clutch will reverse your momentum, meaning that the sooner you perform the clutch after flying, the closer you’ll get to the stage and therefore have a more successful recovery. Players who are new to this type of fighting will not be left in the dark here, as there is a great tutorial mode. The tutorial is very interactive with the player, giving them everything they need to get a basic grasp on how the game works. You can also read about the various mechanics that are available in-game, what they do, and how to do it, as well as get a bio on each character and what their moves entail.

  • Go on an epic quest as a not-so-average clown trying to find their dog in Ayo the Clown

    Ayo the Clown is an upcoming adventure platformer from developer Cloud M1, it should be releasing this year and it looks so full of charm it could pop like a balloon at any moment. Funded on Kickstarter back in September 2019 with 475 backers pledging $20,397 we totally missed this, it even had a Linux demo back then too. Cloud M1 said their take on the busy platformer genre is one that's supposed to "reintroduce you to the incredibly fun platformer games of the ‘90s where platforming is accompanied by an inspiring and memorable story". It has a pretty amazing style, one you can easily say is quite Nintendo-like.

  • Valve rolls out News Channels onto Steam to follow your favourite curators - like us!

    Over time Steam continues to grow as much more than just a games store, and Valve are showing how today with their next Steam Labs experiment to let you get your news. Steam Labs Experiment 009 announced here is an addition to the News Hub, which is now hooked up with the Steam Curator system. Valve said it's now nearing completion and it's a big stop towards the full launch. This will presumably replace the old Steam news feed.

Vulkan Graphics: Vulkan Portability Extension and More

  • Vulkan Portability Extension 1.0 Now Shipping For Expanding Vulkan's Reach

    The Vulkan Portability Extension (VK_KHR_portability_subset) has been released as part of the effort by The Khronos Group in getting Vulkan running on as many platforms as possible, including the likes of Apple macOS/iOS. The VK_KHR_portability_subset extension is about getting Vulkan up and running on non-Vulkan APIs, as opposed to the success we have already seen in areas like getting OpenGL or Direct3D atop Vulkan. The VK_KHR_portability_subset extension makes it easier for the likes of GFX-RS and MoltenVK for getting Vulkan running on platforms like Apple's operating systems where Vulkan is not supported and thus having to reside on top of say the Apple Metal API.

  • Mike Blumenkrantz: Dynamism

    In Vulkan, a pipeline object is bound to the graphics pipeline for a given command buffer when a draw is about to take place. This pipeline object contains information about the draw state, and any time that state changes, a different pipeline object must be created/bound. This is expensive. Some time ago, Antonio Caggiano did some work to cache pipeline objects, which lets zink reuse them once they’re created. This was great, because creating Vulkan objects is very costly, and we want to always be reusing objects whenever possible. Unfortunately, the core Vulkan spec has the number of viewports and scissor regions as both being part of the pipeline state, which means any time either one changes the number of regions (though both viewport and scissor region counts are the same for our purposes), we need a new pipeline.

  • POWER Coregroup Support Coming With Linux 5.10

    There is some new feature code in the IBM POWER CPU architecture's "-next" Git tree for the Linux 5.10 kernel. Queued up this past week is coregroup support for POWER processors on Linux. This includes a cleanup of the PowerPC topologies code and adding the Coregroup support, which in this context is about a group/subset of cores on a die that share a resource.
