A study from a British think tank purports to show definitive evidence of electoral fraud in Iran; Juan Cole backs the study up with some analysis. Violence has been amping up in Tehran over the last few days, with worse likely to come; an article in Time suggests that renewed violence may flare up on the 3rd, 7th, and 40th days following deaths like Neda Soltani's in accordance with Shi'ite mourning practice. This significantly complicates, Jason Zengerle argues, comparisons to Tiananmen.

The Big Picture continues to collected photos from Iran; here are the two most recent updates.

Sunday night links.

* I can't bring myself to watch the murder of Neda Soltani on YouTube, but a lot of other people have. It's remarkable how quickly her face has become that of the protests in Iran.

* The New York Times has an article exposing abusive practices in the freelance textbook market in New York, with my good friend and old co-blogger PClem providing some of the ugly details.

* Polls show widespread public support for a public health care option. Will this remind Democrats in Congress that they swept the last two elections?

* Buffy vs Twilight.

* Infinite Summer begins tonight. Kottke kicks things off.
