Thu, 14 Feb 2008 05:23:44 +0000 http://efaller.com/blog/2008/02/09/server-noise/#comment-6961 no. not looking for a new job at the moment.

There was just a rep from your company that came and talked to our class. He handed out business cards and i got curious. My sister does work for a company you recently acquired however.

I figured it was some crazy computer related thing

That means that you have to count higher before you get to 10. They use A (hex) to represent 10 (decimal), B for 11, etc. Each hex digit is 4 bits. 8 bits are usually used to represent one character, i.e. a-z (lowercase) or A-Z (uppercase), since there are 256 combinations of 8 bits, enough for every letter and then some. With 4 bits, that just doesn’t cut it. Since the repeated sections start half-way through an 8-bit “letter”, it implies that there’s more to this code than it just being scrambled 8-bit letters…

Hopefully I explained that well!

And I’m supposed to be a computer scientist. :( Yeah, the long repeated section is odd, given the 4-bit alignment.

3b 96acc949 5092c3b9

It’s in both the first line and the second line, and it seems much too long to be a coincidence

I think that could be just a coincidence given the 16 combinations possible in 4 bits. I do think an 8-bit boundary condition exists, though. I even tried to see if it was ARM or thumb assembly before I noticed the 8-bit boundary condition. ;)

People keep posting stupid crap on his profile.

About the puzzle – hmm, that’s interesting. It’s apparently a Microsoft recruiting trick, so I probably can’t post the answer on the internet :) . It’s interesting since there are several repeated sections, and one of them occurs on a 4-bit boundary, indicating that it’s probably not using a simple byte alphabet.

Tue, 12 Feb 2008 21:25:49 +0000 http://efaller.com/blog/2008/02/09/server-noise/#comment-6971 hey this has absolutely nothing to deal with your post, but i was assuming you know the answer to my question… partially because its from the back of a MS Business card, but mostly because you’re the man.

Can you solve this?
