Categories in Jekyll have annoyed me for a while because of the URLs generated.
The path would be something like /tag1/tag2/year/month/day/title which works
so long as you don't change the categories used. Since tags are also an option
and don't have the same issue I've switched. I followed this post about
tagging archive pages in Jekyll that
made it rather painless.
A recent task of mine was to add some metric collection to a Rails application at SeatGeek. One of the main components (and critical if there was a problem) is the set of Resque background workers. There is actually a Resque Plugin (abandoned, maintained that will collect stats. The gem sadly is not maintained so I forked the maintained repo in order to provide a stable source. I use the commit hash to make sure I get the version but if the repository we used disappears that would cause problems, so a fork solves that.My fork doesn't change much except for some of the paths used for the metrics. At some point I may clean up the README and package my first gem.
