[Build] electrical

Thu Aug 20 04:27:38 UTC 2009

Hey Guys,

The trick to harnessing the Noisebridge Random Interest Machine is to divide
the tasks that need to be done into bite-sized chunks and let everybody know
what the tasks are; then you end up showing up to find tasks mysteriously
done.

For example, all the wood and sheetrock and whatnot that used to be our
walls need to be moved from the pile near Mission to the Linoleum near the
DJ booth, so that it's not creating a big pile of hazard impeding work on
the floors, so any time anybody is in there, that's an easy thing to just
do.
