I recently discovered MisterHouse because it has a module to talk to my Pentair Compool pool controller. I'm documenting my experience here: http://carlstrom.com/pool/
I've found MisterHouse documentation to be frustrating but I've gotten it to do what I need so far for my pool project (allow remote control and to log temperature information over time). I will say that it could use some serious rearchitecture to go along with some better documentation. If I were going to do some more serious HA I would consider trying to improve things, but its good enough for my needs, so I'll just be submitting some minor bug fix / corrections...
I've been happy using my old HP OfficeJet printers under Ubuntu with HPLIP. It is nice to see a mainstream vendor actually support their hardware under Linux. I had thinking of ditching HP for Canon until this. I've been using it more for bulk scanning with the automatic document feeder that industrial printing, but I thought it was worth mentioning.

Great idea. I just emailed Rep. Anna Eshoo. Hopefully other Silicon Valley nerds will do the same. Here is the URL:
Do not simplify the design of a program if a way can be found to make it complex and wonderful.
