I'm definitely going.
There's still 3 spaces over on Doorkeeper https://trbmeetup.doorkeeper.jp/events/28319
The presentation is titled "900K records per second with Ruby, Java, and JRuby".
Nakamura san will be speaking about the system architecture behind Treasure Data ( http://www.treasuredata.com ) - a cloud analytics service which stores over 16 trillion records of customer data. The company was founded by two Japanese engineers and now has a number of big investors such as Jerry Yang the founder of Yahoo and James Linderbaum, co founder of Heroku.
Should be a very interesting presentation and the speaker Nakamura san is not only extremely talented (CRuby and JRuby committer) but a really nice guy too.
Anyone else on Canvas going?
