Graphication. Andrew Godwin’s Python graphing library, based on Cairo. Responsible for the very handsome graphs on The Carbon Account. # 7:05 pm

The Carbon Account. The carbon calculator project I contributed to at Torchbox last year has launched, and they’ve made the code available as open source. # 7:04 pm

Interviewing Simon Willison about OpenID. I sat down with Vikram Kumar at Webstock to talk about OpenID, and the video is now online. # 6:40 pm

hash. Douglas Crockford: “Any HTML tag that accepts a src= or href= attribute should also be allowed to take a hash= attribute”—to protect against file tampering and (more importantly) provide a truly robust caching mechanism. # 6:34 pm

Exposing calendar events using iCalendar in Django. A simple abstraction around the vobject Python library. # 6:31 pm

Google’s excanvas only works in quirks mode for IE8. IE8 in act-as-IE8 mode disables VML but doesn’t implement canvas, so there’s currently no 2D drawing method for that browser. UPDATE: The problem is Google’s excanvas library, not IE8 disabling VML; see comments. # 6:24 pm
