mdepub is a tool that allows you to compose a book in Markdown format and use Pandoc and Calibre to compile an Epub package including all of the book's source material. In effect, you can keep the source and product in the same file in your library; if you ever want to revise the product, you merely need to extract the source, make edits, and recompile.
ECommands is intended to make it easy to execute commands over Unix/Linux Servers using a Web interface. It was implemented completely in Python and Django, and it will work from automation processes to generalization commands. It allows centralized administration, better understanding of repetitive and complex operating systems commands, connections made over SSH to multiple servers using a Web console, auditory feedback over the execution of commands processes on servers, multiple users and permissions, easy installation on 64-bit Linux, grouping commands, and more.
Bibulous is a drop-in BibTeX replacement based on style templates. It provides all of the functionality of BibTeX, while adding the ability to work with large-scale databases, multilingual data, localized sorting, and a lot more. Its outstanding feature is that users can define new bibliographic styles in a matter of minutes without mastering the details of any user guide and without needing to understand the underlying code. This is possible through the use of style templates, which are ideal structures for defining the format of a bibliography.
Darning is a tool for managing a series or sequence of patches to a software source tree, in the same vein as quilt but with extended functionality. It supports advanced patch concepts such as file mode changes and copying/renaming files. The GUI is the primary interface and the most complete, but a command line interface is also provided with fewer features at this stage.
CrutziPlayer is a standalone player for NPAPI-based browser plugins (e.g., Flash). It provides external, hardware accelerated fullscreen scaling using XComposite, Cairo, and XFixes. It's a good solution, for example, for playing browser games fullscreen on Linux, as it autodetects the original .swf content size.
