Roles UI is a graphic interface library for Ruby on Rails which provides the ability to manage roles and permissions in realtime for applications which use Cancan. It is a Rails engine, so it has its own namespace. You can reach Roles UI in /roles_ui. Roles UI consist of two main entities, Role and Permission. Each Role may have a permission set. Roles belongs to users. Roles UI extends your User model so you don't need to create this association. By default, Roles UI is configured to work with the User model.
Coquelicot is a “one-click” file sharing Web application with a focus on protecting users’ privacy. Its basic principle is that users can upload a file to the server, and in return they get a unique URL which can be shared with others in order to download the file. Coquelicot aims to protect, to some extent, users and system administrators from disclosure of the files exchanged from passive and not-so-active attackers.
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.
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.
