BusyBox

BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete environment for any small or embedded system.

BusyBox has been written with size-optimization and limited resources in mind. It is also extremely modular so you can easily include or exclude commands (or features) at compile time. This makes it easy to customize your embedded systems. To create a working system, just add some device nodes in /dev, a few configuration files in /etc, and a Linux kernel.

Common Workflow Language

The Common Workflow Language (CWL) is a specification for describing analysis workflows and tools in a way that makes them portable and scalable across a variety of software and hardware environments, from workstations to cluster, cloud, and high performance computing (HPC) environments.

Harvey OS

Harvey is a new operating system. It’s most directly descended from Plan 9, the research operating system developed at Bell Labs as a successor to Unix. This influence spans from its distributed application architecture all the way down to much of its code. However, Harvey aims to be a more practical, general-purpose operating system, so it also uses ideas and code from other systems.

Harvey strives to provide an accessible development environment. The kernel is compact—less than 100,000 lines of code. You can build it with either GCC or LLVM, and run it under QEMU or real hardware. This makes it especially suitable for education and experimentation. It is a work in progress and the development team welcomes new contributors and ideas.
