Inspired by a comment on my post Visualising edit history of a Wikipedia page, the code I use to make history flow diagrams like the one below is now in GitHub at https://github.com/rdmpage/wikihistoryflow.There is also a live version at http://iphylo.org/~rpage/wikihistoryflow.

Stumbled across Alex Wild's post Pyramica vs Strumigenys : why does it matter?, which takes as it's starting point a minor edit war on the Wikipedia page for Pyramica . Alex gives the background to the argument about whether Pyramica is a synonym of Strumigenys , and investigates the issue using the surprisingly small about of data available in GenBank.

Quick post (really should be doing something else). Reading Jeff Atwood's post Mixing Oil and Water: Authorship in a Wiki World lead me to IBM's wonderful history flow tool to visualise the edit history of a Wikipedia page. There's a nice paper describing history flow (doi:10.1145/985692.985765, free PDF here). Inspired by this I decided to try and implement history flow in PHP and SVG.
