			GetIt's main focus is to make your life a lot easier when you have to test APIs or use somebody else's API.
			We know it can be hard to find a great, simple and open source application for this task that's not command
			line based.
		
      
			You can send numerous requests to a webserver. You can send RAW post data, form post data, add cookies to your
			request and add headers to your request.
		
      
			The response can be viewed either as syntax highlighted code, with JSON even being made readable,
			as the raw output, which means no syntax highlighting, and view it in a webview.
		
      
			Features of GetIt include:
		
      
        Sending HTTP requests to API endpoints and display the response of the server
        Saving and opening requests
        Easily open recent saved/opened requests
        Sending custom POST data
        Syntax highlighting for all responses
        Preview for HTML response

      Pure Data (or just "Pd") is an open source visual programming language for multimedia. Pure Data is developed by Miller Puckette since 1996 and you can find it on his official website along with the official documentation and other related resources. This is the official "Pd" or "main distribution" and it is also known as "Pd Vanilla".
    
      
      Think of Pd as a &lt;em&gt;Modular Synthesizer&lt;/em&gt; that is also a programming language.
    
      
      Pd's audio and MIDI functions are built-in as well as networking (e.g. using Open Sound Control), but there are a number of external libraries that allow you to do graphics, interface hardware and much more...

Official development environment for Inform, a programming language for creating interactive fiction, using natural language syntax. Using natural language and drawing on ideas from linguistics and from literate programming, Inform is widely used as a medium for literary writing, as a prototyping tool in the games industry, and in education, both at school and university level (where Inform is often assigned material for courses on digital narrative).The Inform project was created by Graham Nelson in 1993 and first came to the Macintosh Programmer's Workshop in 1995, and is now available as an app. It combines the core Inform software with full documentation, including two books and nearly 500 fully working examples. Connecting to the Inform website, it can automatically download and update extensions from a fully curated Public Library used by the world-wide Inform community. The app offers richly detailed indexing of projects and scales from tiny fictions like "Kate is a woman in the Research Lab" right up to enormous imaginary worlds whose source text runs to over 3 million words. Features for automated testing, packaging and releasing round out a fully-featured development environment for IF.Inform is free, with no strings attached. What you make with it is yours, to publish on your website, sell, or give to your friends. There's a vibrant community of users who welcome newcomers (and the app will help you find a high-traffic forum for discussions). Lastly, Inform is continuously maintained and developed. All bug reports are examined and acted on (and the app will show you how to post them).The source code behind the Inform 7 design system itself is linked here: https://github.com/ganelson/inform/The source code behind this IDE is linked here: https://github.com/ptomato/inform7-ide/

&lt;em&gt;NOTE: This Flatpak is unofficial and not supported by Godot Engine developers.&lt;/em&gt; Find officially supported binaries on godotengine.org.Godot is an advanced, feature-packed, multi-platform 2D and 3D open source game engine.Create games with ease, using Godot's unique approach to game development.Nodes for all your needs. Godot comes with hundreds of built-in nodes that make game design a breeze. You can also create your own for custom behaviors, editors and much more.Flexible scene system.

It even works on mobile devices!Create your own custom tools with ease using the incredible tool system.Limitations of the Flatpak version:Although built with Mono 6, this Flatpak uses .NET 8 for building C# solutions in Godot projects. To (re)build a C# solution in the Godot editor, make sure that "Editor -&gt; Editor Settings --&gt; Mono --&gt; Builds --&gt; Build Tool" is set to "dotnet CLI", and not "MSBuild (Mono)", before (re)building the C# solution, otherwise Godot won't be able to find MSBuild. It should be set to "dotnet CLI" by default, but if it isn't, reset it by going to the editor settings as previously described.C#/.NET/Mono external editor support does not work out-of-the-box, though this is currently being discussed and worked on. See: https://github.com/flathub/org.godotengine.GodotSharp/issues/2 and https://github.com/flathub/org.godotengine.Godot3Sharp/issues/2External script editors are still supported (for use outside of Mono), but you need to follow the steps described here: https://github.com/flathub/org.godotengine.Godot3Sharp#using-an-external-script-editorAfter the first C# script is created, it is necessary to click build within Godot. Alternatively, running dotnet restore in the IDE's terminal would work as well.

Vivado Design Suite is a software suite designed by Xilinx for the design, synthesis and analysis of HDL for its line of FPGAs and SoCs. Vivado Design Suite includes many tools, like Vivado, Vitis, Vitis HLS and many others. This package provides a flatpak wrapper over an official installation. As the Xilinx tools are not redistributable, this package does not contain any Xilinx-licensed material, which is instead downloaded on-the-fly through the official Xilinx installer. To install it, install the flatpak package, then run any Xilinx launcher and follow the instructions. To uninstall, just remove the flatpak package to remove this wrapper. Note that this does not remove the Xilinx installation; to remove it, run the launcher "Uninstall Xilinx Design Tools or Devices" (or run "flatpak uninstall com.github.corna.Vivado --delete-data" to wipe everything in in "~/.var/app/com.github.corna.Vivado/").Why can't I see some of my files in Vivado? - All the Xilinx tools handled by this wrapper run in a sandbox with limited filesystem access, only your downloads, documents and desktop folders are visibile. Either work in those directories or override the default permission (with "flatpak override com.github.corna.Vivado --filesystem=&lt;path_here&gt;").I get an error "Can't open project [...]. Please verify that the project still exist.", why? - Same as before, make sure that the project is in one of the allowed folders.I have created a project outside Desktop or Documents: where are they? - You can find the sandboxed filesystem in "~/var/app/com.github.corna.Vivado/".I can not access the hardware devices. - Have you installed the "cable drivers" (which are just udev rules) at the end of the installation? To install them, run: "cd ~/.var/app/com.github.corna.Vivado/data/xilinx-install/Vivado/&lt;version&gt;/data/xicom/cable_drivers/lin64/install_script/install_drivers/ &amp;&amp; sudo ./install_drivers &amp;&amp; sudo udevadm control --reload", then re-connect any hardware device.Can I deny internet access to the Xilinx tools? - Yes, just remove the corresponding permission with: "flatpak override com.github.corna.Vivado  --unshare=network". Note that the license manager uses your MAC addresses, so you may experience issues with non free components.How can I install additional components? - Run the launcher "Add Xilinx Design Tools or Devices".Can I install an additional version of the Xilinx tools? - Yes, run "flatpak run --command=xilinx_install com.github.corna.Vivado".How can I remove a particular version? - Run the launcher "Uninstall Xilinx Design Tools or Devices".NOTE: This wrapper is not verified by, affiliated with, or supported by Xilinx, Inc.

      KCachegrind is a profile data visualization tool, used to determine the most time consuming parts in the execution of a program.
    
      Features:
      
        KCachegrind visualizes profiles (i.e. runtime characteristics) of applications in various ways,
          including call graph vizualisations and source/disassembler annotation.
        It can load profiles generated by the cache simulation/call tracer Calltree, a Valgrind tool.
          Thus, profiling does not need any preparation, can cope with shared libraries and plugin architectures, and does not influence the measuring itself.
        Converter scripts for OProfile, Perl, and PHP.
        Switching between multiple visualization layouts.
        Call graph can be exported as image (PNG).
        Simultaneous display of 2 event types in Call and Annotation View
