Revised is a visual editor (or wizard/assistant/GUI) for Ren’Py, the visual-novel game editor. Ren'Py has a lot of capabilities, and Revised's purpose is not to allow everything that Ren'Py can do, just some of the basics. You can think of it as a step-by-step wizard to create the skeleton of a Ren'Py game.
sVimPy is a very small Python virtual machine intended for use in microcontroller projects. At the moment, it supports about 3/4 of all opcodes used in python3k. Most data types are supported. The intended goal is to use this VM in environments like Atmel's ATmega chips (2-8kb RAM). The microcontroller bootloader is still missing (no arduinos left for experimentation). Classes are not supported. Features include: function calling, a stack based VM, garbage collection, very low memory usage, an interactive debugging console, dictionaries and tuples, iterations, VM single stepping (game loop usage is possible), C function calling, a small memory footprint, fast performance, the ability to be used as a library in other projects, a simple API + code, possible usage as a small deployment executable for Python projects.
Stem Desktop is a minimalistic Debian desktop for low-end hardware with limited memory (166Mhz / less than 64M). The goal is to find programs that have the smallest possible memory footprint. After installing *.deb packages on top of clean Debian, the desktop is ready to accept graphical logins.
Runner is a simple and fast X11 menu for starting commands. It's meant to be a fast start menu for often used programs. It also contains a run dialog to enter arbitrary programs or select programs from a history file. It supports completion both from the history as well as the $PATH variable. It's also optimized for keyboard usage.
If you're a developer of multiple projects, you'll find yourself needing to switch between multiple different version control systems. After working in one (e.g. SVN) for an hour, you may need to switch to a different one (e.g. git). Getting your fingers to switch is the difficult part, or remembering the right command line flags to use for the given tool. That's where The One Ring comes in: it provides a constant interface to all the version control systems, and your fingers only need to remember a single command regardless of what checkout directory your shell is sitting in.
