position:fixed in IE, no Javascript required
Via Craig Saila, a method for getting IE to apply position: fixed without resorting to Javascript. It uses a conditional comment (slightly ugly but perfectly valid HTML) and works a treat. Kudos to Eric Bednarz for clearing up another of those niggling CSS problems.
Experimental feature: Related entries
I’m experimenting with using MySQL full text indexing to generate a list of “related entries” for each entry (click on an item’s permalink to see it in action). It works by concatenating the item’s title and entry body together and running a full text search on it, which sounds horendously inefficient but seems to work surpsingly quickly. If I decide to keep the feature I’ll probably cache the results somewhere to reduce the overhead, but for the moment it’s fast enough.

I’ve finally got around to adding a search page to this site. It uses MySQL’s full text indexing, which is extremely fast and provides good results but comes at the expense of flexibility. Search terms less than 4 letters long are ignored, and multi-word searches are handled using OR rather than AND. This nearly put me off using it, but the relevancy algorithm is excellent which I think outweighs the disadvantage of not being able to use pure AND queries.
