cascadenik: cascading sheets of style for mapnik. Great idea. Mapnik (the open source tile rendering system used by OpenStreetMap and others) has a complex style configuration based on XML. Michal Migurski has build a CSS-style equivalent which compiles down to XML, hopefully making it much quicker and easier to get started with Mapnik customisation.

addSizes.js: Snazzy automatic link file-size generation. Posted to Nat’s snazzy new blog: a script that uses my json-head API to grab the file size of linked documents on a page and insert those sizes in to the document.

Google’s undocumented favicon to png convertor (via) Showing the favicon of a domain next to a link is a really nice trick, but it’s slightly tricky to achieve as IE won’t display a .ico file if you link to it from an img element, so you need to convert the images server-side. This undocumented Google API does that for you, meaning it’s much easier to add favicons as a feature to your site.
