I wrote a very short draft about a geeky command that we can find in Fedora: espeak.
Espeak is speech synthesizer, a command line tool that can speak text from a file or from standard input.
There is not much to say about such command: some ideas, an example. In any case I find it amusing, but at the same time useful to raise talking Nagios alerts from my laptop, like a nerd. :-)
Ciao A.
