Microsoft’s vscode source code is open source (MIT-licensed), but the product available for download (Visual Studio Code) is licensed under this not-FLOSS license and contains telemetry/tracking. The VSCodium project exists so that you don’t have to download+build from source. This project includes special build scripts that clone Microsoft’s vscode repo, run the build commands, and upload the resulting binaries for you to GitHub releases. These binaries are licensed under the MIT license. Telemetry is disabled. If you want to build from source yourself, head over to Microsoft’s vscode repo and follow their instructions. VSCodium exists to make it easier to get the latest version of MIT-licensed VSCode. Please note that some Visual Studio Code extensions have licenses that restrict their use to the official Visual Studio Code builds and therefore do not work with VSCodium.

Compile Elixir applications into single, easily distributed executable binaries. Bakeware extends Mix releases with the ability to turn Elixir projects into single binaries that can be copied and directly run. No need to install Erlang or untar files. The binaries look and feel like the build-products from other languages. Since everything was written quickly and the integration is fairly straightforward, we recommend that you take a look at the examples. The examples are bare bones Elixir scripts, OTP applications, Phoenix applications and more with small changes to their mix.exs files and instructions for running that you can try out for yourself. Assemble the necessary components to create a Bakeware executable that can be distributed across machines to run the script/application without extra environment setup (such as installing Elixir/Erlang, etc).

Need to create binary files with data for Your program, game etc.? Tired of using hex-editor and editing the file manually with the risk of structure-mismatches? Too lazy to reedit complete file after changing structure members order or size? "data2bin" is a utility that takes: 1. Your structures description (you can use integers of different sizes and endiannesses, null-terminated text strings, fixed-size binary strings, structures, arrays...) 2. Your data in a XML file written down according to defined structure. ... and produces final binary file. It is able to pad Your strings with defined padding, check Your integers' sizes, it can fill default values where You didn't supply data, it can also, for example, put a "blank" array member at the end of an array etc. Whenever You change your structure in Your code, just update the data-description file and "rebuild" Your binary files without touching XML data files!

A clone of the "binhack" program made by Echelon used to hack LBA references in Sega Dreamcast Katana executables. Some features are added on top of the original ones; namely patching the bootsector to enable the VGA flag and setting the OS flag to 0 if a "bincon"-ed binary (boot.bin) is detected. The purpose of this project is to replace the original Echelon's "binhack" utility on systems that don't support 16-bits x86 binaries (e.g. Windows 7 x64).
