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.
This is a simple command-line utilitiy to convert images from TIFF to PNG format. It is primarily useful in dealing with TIFF images that contain alpha channels (transparency information), since the NetPBM suite is (currently) ill-suited for such conversions. A few test images are included.
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).
