Some things to keep in mind if you are writing applications for the "new facebook".

Quoted: On the canvas page you can prompt the user to allow your application to access more information and ask for additional permissions. This is essentially the same as what we earlier announced as authorizing an application, but now the experience is even more lightweight -- see the sample login dialog to your right. This Ajax dialog replaces the current add page and the login screen you saw in earlier posts.

We inadvertently provisioned a few database machines with MyISAM instead of InnoDB, and it has been a nightmare. I strongly advice against using MyISAM -- ever.

With MyISAM, we periodically get these incorrect "duplicate key" errors that don't go away until you run the lenghty "repair table" command that somehow fixes everything.

Quoted: Use MyISAM when: The data isn't too critical ( "unreliable and slow, related to table size, table repair process" )
...
Use InnoDB for tables when: The table will be big (100Mb+ - "For reliability and performance, we use InnoDB for almost everything at Wikipedia - we just can't afford the downtime implied by MyISAM use and check table for 400GB of data when we get a crash." )

Instructions for Facebook application developers re: integrating with the new Facebook design.

Quoted: We’re getting ready to launch some significant changes and improvements to Facebook, including a new profile for users and a new navigation bar for the Facebook site. These changes are intended to help users communicate and share information more easily with each other - on their profiles, through applications, and through News Feed.

There is some useful stuff here.

Quoted: Facebook has been developed from the ground up using open source software, and we are proud to give back to the open source community through various open source projects.

I've been waiting for something like this.

Quoted: Amazon DevPay removes the pain of having to create or manage your own order pipeline or billing system. It allows you to quickly sign up customers, automatically meter their usage of AWS services, have Amazon bill them based on pricing you set, and collect payments.

Quoted: A truly scalable ASP.NET Web site makes optimum use of the thread pool. That means making sure request-processing threads are executing code instead of waiting for I/O to complete. If the thread pool becomes saturated due to all the threads grinding away on the CPU, there's little you can do but add servers.
.
However, most Web apps talk to databases, Web services, or other external entities, and limit scalability by forcing thread-pool threads to wait for database queries, Web service calls, and other I/O operations to complete.

I am going to use this to clean up the html for some of the sites I maintain. The author (Omar Al Zabir, CTO of pageflakes) is one of the best .Net developers around.
