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.
tinyHeb is a Web application for midwives in Germany to do the legal accounting with the health insurance companies. tinyHeb can produce paper and electronic bills, and meets the legal requirements of §301a, §302 SGB V, resp. tinyHeb is already certified by AOK Rheinland, AOK Bayern, and ARZ Emmendingen, which means that the midwife is allowed to send electronic billings to all AOK and the most BKK's in Germany after a very short testing (three bills). Paper bills can be sent for insurance companies that are not supported.
tinyldap is a small (11k uncompressed static binary on x86 Linux) and fast (1000 equal queries for one of 3000 records in less than one second on a 1.3 GHz Athlon, with over 3000 separate TCP connections using tcpserver) read-only LDAP server. No tricks like file descriptor passing, thread pools, or caching are used (aside from the buffer cache from the operating system).
