Two phrases I'm sick of hearing; "open source" and "arduino"

they are called "cracker" last time when i got involved in such a thing... not "hacker". cracker only want the exploit, not want to invent, find or think!

well they seem to be more interested in a system level design than a device level design, some have electronics knowledge but I suppose when you doing a social design it's easier to take existing modules than start designing at a component level.
