# The first cut of the experimental Opened a bug for 404 extension is nearly donehandling: https://bugzilla.** Intercepts 404s and suggests alternatives drawn from the places DBmozilla.** Uses a cheesy edit-distance approximation implemented entirely in Sqlite SQLorg/show_bug.cgi?id=482874
# Made contact Completed the experimental 404 extension and sent it out for comments.** Works well for simulated small errors in URLs** Hard to say how well it works for real errors in the wild.** Drawing alternatives from the Places DB looks like a practical tool we can use for suggesting alternatives. # Discussions with the Google Link Doctor teamare ongoing, if slow. (Our fault, not theirs)** Follow up on experimental access to the service. # Discussed possible 404 implementation with bzbarsky and others.** 404 interception unified with the existing error handling architecture is too deep a change to make for 3.1.** A less intrusive approach similar to the one the experimental 404 extension uses may be possible -- need to investigate further. # Discussed UI design with jboriss. She has a blog post on the subject at http://jboriss.wordpress.com/2009/03/10/improving-everyones-favorite-feature-404/. # Implemented Levenshtein Distance algorithm in C++, but have not plugged it into Firefox+Sqlite yet. Should provide better performance and accuracy compared to the approach used in the extension. # Proposed a plan for actual implementation -- see below.
