multi-rsh is a perl script which runs the same command on multiple machines, in parallel, and provides reasonable, adjustable timeouts for those machines which fail to answer. Both standard output and standard error are returned through the same channel, and all output has the hostname prepended to each line. Multi-rsh must be run as root (remote jobs can be set to run as any user, see Options below). ... Neither form allows you to directly pass input to the remote programs. ...

A spherical meteorite of radius 3m enters the Earth's atmosphere at an altitude of 100km and a speed (relative to the Earth) of 30 km/s. The atmosphere slows it down, so when it hits the Earth's surface it is travelling at only 1 km/s. If half of the heat generated as it passes through the atmosphere is absorbed by the meteorite, how hot will it be when it is about to land? ... However, the number I calculated (500,000 K) is correct, as is the discussion that follows it. ...
