At Yahoo!'s Taiwan Open Hack Day 2009, Yahoo hired female entertainers who danced for attendees and gave male participants at the event lapdances. This is an example of a Sexualized environment at a Technical conference.
These images were made private on or about 21 Oct.
Post with images and links, and critical commentary:Not My Gal, 20 Oct. 2009.
Simon Willson wrote up a blog post containing screencaps from the now-removed lapdance video. There was considerable reaction on Twitter, including a petition, critical tweets from Caterina Fake (founder of Flickr, which was acquired by Yahoo! in 2005) and Chad Dickerson (CTO of Etsy), and this response from Rasmus Lerdorf (creator of PHP).
The original Yahoo Developer blog recap of the day contained no mention of the dancers, except in the comments where people ask for an explanation. During the event, the official Yahoo Developer Network twitter account tweeted
Hack Girls show perked up all the hackers, now back to their computers http://bit.ly/1zwatP
Some time later, this tweet was deleted, and replaced with
