I had some followups to issues that came up at Tuesday's meeting. IRB (Interactive Ruby) is a convenient way to experiment with Ruby. It's a command line...

I don't expect that many people will have done all the exercises before the meeting, so we'll be pairing on them during the meeting. Don't read a solution...
Actually, the first solution there has a typo. Must have gotten the earlier draft. A correct solution would be: File.open("sampleOutput.txt", "w") { |file| ...
There are books on code reviews listed here: <http://c2.com/cgi/wiki?CodeReview> As much as I like Jerry Weinberg's books, this one: [ISBN 0-932633-19-6]...

I was talking with another programmer who uses Ruby, Bill Clagett, and he came up with a different way to solve the interleave problem. We were talking about ...

Hi Robert, I thought I'd post our interleave solution to add to the mix. Thank Eric Vautier for coming up with the algo. def interleave(s, t) retval = "" for i...

I'm still trying to figure out a good way to keep Yahoo from losing indentation on code snippets. Since the last experiment didn't work, I'll try using...
Here are all the new exercises, plus two even newer ones at the end. (To keep the formatting looking nice, periods are used at the front of lines, instead of...
