Things Computer Scientists Know

Thanks for coming to the first talk in this series last week! I promised I'd post up a gist of the problem for Recursion part 2, and I'll publish that to this list tonight. Until then, here's a preview of the puzzle for "What Computer Scientists Know: What goes on 'underneath'"... Where we talk about binary, hexadecimal, and machine code.


Once again, this problem has a recursive and an iterative solution. A few people at RubyLoco Monday night did the problem with me, and I learned one of the coolest things about the ruby language from Ryan McGeary... but that'll have to wait for the talk!
