Xenograte Community Toolkit is based on Xenograte, a platform which enables users to manage and orchestrate worker processes, and easily design the flow of data shared among them. Xenograte works either on one server or across multiple servers/clouds. The Toolkit provides a CLI and other resources for building, testing, and debugging worker processes, in Ruby, on a single machine. You can then easily weave these worker processes together into powerful integrations or automations.

It is especially useful for translating from the CJK languages (Chinese, Japanese, and Korean), and it is very suitable for working with ancient and otherwise difficult texts. Unlike most other machine translation systems, Sanzang is small and approachable. Any user can develop his or her own translation rules, and these rules are simply stored in a text file and applied at runtime.

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.
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.
