Laszlo, InfoBlox and the Wikipedizer.
That's the best blog title I've ever had. It barely resembles English.
I spent the last couple of weeks playing with the newly open-sourced Laszlo. The result is InfoBlox -- kind of an alternative to the standard blog sidebar. It's pretty easy to embed one of these on your website -- go ahead and do so if you like, though I'll probably move it over to mylaszlo so I don't have to host it forever.
The other side-effect of the playing was the wikipedizer, a web service I wrote based on a cool idea that was making the rounds a few weeks ago. Basically, you pass it a URL and returns a list of Wikipedia entires related to the page in question. The source code is there too, so, uh, embrace and extend!
For the record, writing code while bouncing a 4-week-old is difficult but entertaining.
