tag-not-ed is a system that allows you to create and manage text documents by attaching tags to them. Later, documents can be retrieved by running queries on those tags (e.g., "show me all docs that deal with 'dogs' and 'cats'"). It is composed of a front-end (currently a mode for the jed text editor) and an indexer. The latter can be used to implement a rudimentary "tagging file system".
TaylorType is a program that speeds up the creation of LaTeX documents. It will compile any LaTeX document you give it with a single click. The emphasis is on a very lightweight and simple GUI. The only interaction happens in the system tray, with two file selectors and a checkbox.
tengis is a bookmarks manager that uses keywords to create a graph of bookmarks, which can then be used for searching. The advantage is that the user doesn't have to choose a single tree node to put his bookmarks in and searching is easier. The implementation binds with external Web browsers, and its file format is extremely simple.
terminal_colors is a tool to display a terminal color chart for 8, 16, 88, and 256 color terminals. It provides all the functionality of the various similar scripts found around the Web with some additional bells and whistles. It automatically detects 8, 16, 88, and 256 color capabilities (via ncurses) and displays the appropriate color charts. It can display the colors as blocks or (2D) cubes, optionally with color values overlaid in int or hex values. It can show the full rgb text string as well. It can also show the display with a vertical (default) or horizontal orientation. It has the option of additional padding and supports -h --help as well. It also works as a utility for converting between 256 and 88 color values.
Termlock blanks a curses-compatible character terminal (e.g. xterm, eterm, PuTTY, konsole, dtterm, etc.) and locks it. To unlock the terminal, a password must be entered. The password, or rather the password hash, is stored in ~/.termlock. Basically, it's like a password-protected screensaver for character terminals. Written in pure Python, it should be immediately usable on any machine with Python and curses (or a compatible library such as ncurses) installed.
