a2b invokes conversion tools in sequence to convert files from one type to another, possibly performing some extra processing along the way. Itis a wrapper for many programs like gif2png, latex2html, netpbm, mencoder, ffmpeg, oggenc, etc., that can convert content from one type to another. It can covert text, documents, images, audio, and video and more. Some examples: a2b test.mp3 test.ogg; mencoder_opts="-ss 60 -endpos 10" a2b video.avi clip.flv; a2b -g=subtitles dvd://8 movie.sub; a2b -q http://sam.nipl.net/ sam.aac. That last example downloads the author's Web page, converts it to text with lynx -dump, speaks the text with flite or espeak, and converts the audio file to AAC with faac.
QuickTile is a simple attempt to duplicate the basic functionality of WinSplit Revolution for users who don't like the Compiz Grid plugin. It should work on any X11 desktop with PyGTK 2.2+, a window manager that supports the modern range of NETWM hints, and (if you want internal keybinding) python-xlib.
The Procrastinator's Timeclock is a simple utility for people who suffer from excessive procrastination or distractibility. The utility achieves its benefits by allowing you to comfortably track just how much time your little "one more thing"s are adding up to and by helping to bolster willpower by providing a gentle distraction from temptations. Its design focuses on simplicity, intuitiveness, and a preference for keeping existing users rather than attracting new ones.
neko-install-cd is a development tool for modifying System Rescue CD images. It can also perform many other operations. It has a simple interface with excellent inline help. Operations it can perform include: booting your modified image in a virtual machine, burning the original or modified image to a USB drive, creating patch sets from your modifications (using aufs or built-in helper scripts). All of these operations can be performed directly from your Linux distribution, without having to first boot into the system rescue CD as with the system rescue CD equivalents.
