SLADE3 is a modern editor for Doom-engine based games and source ports. It has the ability to view, modify, and write many different game-specific formats, and even convert between some of them, or from/to other generic formats such as PNG.SLADE3 can be considered a successor to both SLumpEd and SLADE - it combines the features of both, to create an all-in-one editor. Why does it keep the name of what was previously just a map editor? Because it fits :)As with SLumpEd and previous versions of SLADE, SLADE3 is fully cross-platform. It can be run on various operating systems, including Windows, Linux and Mac OS/X. So no matter your preferred OS, SLADE3 is available for you.

Flatpak developer demo application is a companion to the Flatpak developer documentation. It is an example of how to use Flatpak to build and distribute an application, and can be used as a reference implementation.While the demo application uses Qt and the KDE runtime, the basic principles that it demonstrates are applicable to applications that use other runtimes and toolkits.The application demonstrates the use of portals, showing how it is possible to securely access host functions like file choosers, notifications and screenshots. To do this, it uses the built-in support provided by the Qt toolkit. Similar support is also available for GTK.

CraftOS-PC is a fantasy terminal that allows you to write and run programs inside an '80s-style text console.CraftOS-PC emulates the popular Minecraft mod "ComputerCraft", which adds programmable computers to Minecraft using the Lua programming language. CraftOS-PC takes this experience outside Minecraft to allow you to run the same programs anywhere you go.CraftOS-PC provides a set of functions (called APIs) that make it super easy to do simple tasks such as write text to the screen, read files, and more. The simplicity of these functions makes CraftOS-PC great for new programmers, but their power makes it possible to write all sorts of complex programs with less code.If you aren't ready to write programs yet, there's already a large number of programs for ComputerCraft that will work in CraftOS-PC, ranging from simple games to whole graphical operating systems. These can be downloaded through the built-in Pastebin and GitHub Gist clients.
