Okay, so I've got three remaining posts in my "balanced string problem" series queued up, the solution to the problem in another language written already, and one idea for some another language to use next. I also have a second solution in haskell that I think uses a whole new approach that I don't use in other posts, but I don't know if I can adapt that approach to another language.
The main problem is I don't know if I can really show new, interesting stuff in what I have left. Also though, it takes me more time than I have free in a single day for silly recreational writing, so soon there's going to come a day when I don't have a post ready.
