I was more curious than anything else to see if I could get pyrit
working properly, and how this laptop compares to other devices out

I've thought about cooking eggs with a cpu actually, the AC was off at
the office when that heat wave came through a couple weeks ago..
couldn't get permission to use work equipment though.. maybe I'll use
an old thinkpad I have laying around.. would make an interesting
youtube video.. hey, would you look at that a quick search yields a
nice southern gentlemen giving a very nice demonstration:

should do.. bring in a few devices and plug them in on the conference
table - we could all have bacon!

As for my neighbors wifi, even if by some chance I managed to brute
force it I think I wouldn't be using their internet on account of my
girlfriend killing me.
