Rails勉強会＠東京第29回(The 29th Rails Study Meeing Tokyo)

This is a study meeting of Ruby on Rails which periodically takes place once a month since November of 2005. I have attended for over two years. There are many interesting sessions about Ruby on Rails. The meeting usually has 4 tracks and they are separated into two periods with a break time.

If you happened to be interested, how about joining in?

AWS (Amazon Web Service) including S3 and EC2 had downed again (See here)

We may have a need of balancing our services over the several EC2 clones. Fortunately, there have already been several computing clouds on the Internet. But there are no compatibilities between them. Their interfaces should be standardized. I think that the spec would become similar to EC2 because of its accumulated experiences.

BTW, I can't stop recalling the story of Permutation City of Egan.

Insecure OPs easily bring problems to consumers trusting them. I think that there should be a kind of world wide reliability evaluation system for OPs. Suppose every OPs has its score on the list of OPs and they should make an effort to keep its score high. RPs are able to exploit it to know which OP is trustworthy.

But obviously, the list is centralized. This is the SPoF and is a quite big drawback. It should be kept decentralized as well as OpenID itself.
