Unix-style utilities

todist
Input is a list of numbers, one on a line. Output is their distribution, a value and how many time it occurs in the input. Useful for my statistics and performance work.
tostats
Input is a list of numbers, one on a line. Output is some statistics about the numbers: average, stddev, min, max, mid point.

I also have a few non-unix-style utils that are useful (to me), It's a fairly simple multiple machine synchronization by using multicast messages. It's also useful to synchronize on a single machine, running it at the end of one command sequence and running the receiver to wait for it to end and do some other commands. It enables the equivalent of: cmd && othercmd && thirdcmd for multiple branches, so I can run two or more command chains when one ends.
