tich is a "Today In Computing History" Google Gadget that displays an event in history for each day of the year. You'll find out things like: "What joke did Grace Hopper pull the day after the 'first actual bug' was found in the Mark I?" and "Where did the term 'virus' come from?". It can also be used on your own Web site.
TilkIRClog is a program designed for logging chats on IRC channels, written in Python. It doesn't intend to be an IRC client, so it's fully automated and has many useful features. For example, it can automatically send logs via e-mail, and even compress them. It can also be restarted from a cron job after termination.
timeplotters is a collection of command line tools for visualizing temporal data. It is especially useful for visualizing data from ad-hoc program logs, helping you to spot patterns and anomalies that you would not otherwise see by just watching how the program works or by looking at the logs with the naked eye. Its input format is tailored to event types typically seen in program logs, and the visualization methods are tailored to the questions typically asked about program performance (e.g. distribution of activity durations).
timer_entropyd feeds the /dev/random device with entropy data (random values) read from timers. It does this by measuring how much longer or shorter a sleep takes, since this fluctuates by a few microseconds every time. The time for a sleep jitters due to the fact that the frequency of the clocks of the timers change when they become colder or hotter. This program does not require any extra hardware. It produces around 500 bits per second. This program is also usable with virtualized systems.
