Ackr is a very small subset of grep/ack/rak, for lazy developers. grep is a great tool, a very powerful tool, but often too powerful for simple needs. Ackr looks for a search string in all text files and in all subfolders from the working directory, is case insensitive, has no options, doesn't look into hidden folders/files, and displays the search term in a bold font.
Wayland is a protocol for a compositor to talk to its clients, as well as a C library implementation of that protocol. The compositor can be a standalone display server running on Linux kernel modesetting and evdev input devices, an X application, or a wayland client itself. The clients can be traditional applications, X servers (rootless or fullscreen), or other display servers.
musl is a new implementation of the standard library for Linux-based systems. It is lightweight, fast, simple, free, and strives to be correct in the sense of standards-conformance and safety. It includes a wrapper for building programs against musl in place of the system standard library (e.g. glibc), making it possible to immediately evaluate the library and build compact statically linked binaries with it.
Tiling provides a simple window tiling system for Linux. It's for those who cannot (or don't want to) use a tiling window manager like awesome or Xmonad. There is no menu or GUI in tiling. You just (optionally) focus a window, press a keyboard shortcut, and that's it -- all windows in the current virtual desktop are tiled.
Genit is a framework that builds a static Web site, which does not require a server side programming language or database. Generated sites consist only of XHTML code (plus CSS and media). It runs from the command line, is based on XML, and is designed to be simple, readable, and minimalist.
dantalian is a transparent file-tagging system using hard links. Tags (which are directories) can be accessed on the file system level (with or without fuse), allowing maximum interoperability with other applications. Tagging operations are performed with scripts, and can also be hooked into other applications. dantalian is file-agnostic and can be used with any and all types of files. Tags can be organized hierarchically and can also be tagged. With (optional) fuse support, dantalian can also create virtual tags (currently limited to tag intersections (AND), but will be expanded later), which can be accessed transparently on the filesystem level.
