HACK
This display is easy to read on a laptop even in bright sunshine, making it an
ideal tool for outdoor work. The histogram slowly sweeps to the left, giving

runs in a terminal, so you can easily run more than one instance to monitor
multiple radio links simultaneously.

Make Network Backups Hack #83
No need for cumbersome tapes and disks; save your precious data across a
network.
The cost of computing is so low that it is not uncommon to have more than

networking them together, and using them for different purposes. For exam-

two Windows machines, and a Mac. With a large number of computers,
each with important data on it, backups of that data become a very real and
important issue to consider.
The natural assumption when faced with a need to perform backups is to
