ShowSlow is a tool for aggregating and visualizing web site performance information. It is also available as open source tool.


HowDoable HowDoable is a project of mine that helps people keep track of important things by reusing their todo-lists. It also has some predefined tasks like sharing links or creating events on Facebook, Tweeting, emailing, adding musical gigs on LastFM and so on - they speed up on-line tasks.
