They started a series on Security Now! focusing on the basics of computing (starts with this podcast: http://twit.tv/sn233). I just listened to that and then saw this entry for a half adder (which they talk about implementing in the podcast) so I thought I'd link it here in case anyone was interested.
Does anyone else have some good resources about the basics of computing? We studied logic in one of my college math classes a bit, and learned how to implement the basic math functions (addition, subtraction, multiplication, and division) in binary, but I've forgotten a lot of it at this point and find it really interesting. I'm specifically interested in the EE side of things, since I don't know all that much about it (they talk briefly about how a transistor actually works in the podcast at a high level, but I'd love to get a solid reference on this stuff that went from low-level up to the higher levels).
Normally, yes, these off-topics aren't very interesting, but it was to me to see that I wasn't the only one making such a gross scan-misreading of the words.
It's curious to me specifically because this misreading seems so much further from the actual letters than most normal misreadings. Is it because of the strong emotions attached to the name that we're subconsciously more "on the lookout" for it?
