Be careful what you wish for

Well I've been wishing for harder problems to work on. Generally I don't come across too many problems at work that require a lot of brain bending effort to solve. Today one of the junior developers (juneys) was working on a problem that he's spent almost two days on. He talked to me a few times during the day about the problem, but he didn't seem to be making much headway, so I finally dropped what I was doing and went and helped him on this issue. It turns out the problem is a pretty interesting undirected graph. I spent maybe an hour working on it with him, at which point I decided this wasn't a good problem for him to tackle, and sent him packing. The joy of being a senior developer. :)

I'm getting ready to build a solution for the problem right now, which is unfortunately going to keep me from spending too much time on the Nested Sets implementation for Rails. I got some helpful feedback from Glen on the rubyonrails weblog that the blog isn't a support forum for rails, and that I should head over to the rails channel or to the mailing list. I did head to the irc channel, and someone finally suggested I search through the tickets for rails for the nested sets check in. I did exactly that and found some test cases. In any event this will give me some test code to work with. I am envisioning something a little easier to use and set up with the Nested Sets than the current incarnation though. Although as I work through the code, if I decide the current implementation is good I'll post a walk through on how to get it up and running. If nothing else, maybe I'll add an implementation for Transitive Closure tables. :)
