Quoted: Writing web apps today is a tedious and error-prone process. Developers can spend 90% of their time working around browser quirks. In addition, building, reusing, and maintaining large JavaScript code bases and AJAX components can be difficult and fragile. Google Web Toolkit (GWT) eases this burden by allowing developers to quickly build and maintain complex yet highly performant JavaScript front-end applications in the Java programming language.

So do you need to install the .net 3.5 framework to run .net 3.5 assemblies, or will these assemblies work with .net 2.0?

Quoted: Yesterday I had a discussion on an internal Microsoft Developers meeting about the status of .NET 3.5. We had presented that .NET 3.0 is an extension of .NET 2.0, and not a new version. My statement that the status of .NET 3.5 is the same, it is basically .NET 2.0 with extra features, was received sceptically.
Just to prove I'm right, here my observations.

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.

Looks like a great set of tools for MySql.

Quoted: Essential command-line utilities for MySQL (formerly MySQL Toolkit)

Integrate Google Calendar on Wordpress.

Quoted: The Wordpress Google calendar plugin allows for the integration of a Google calendar into a Wordpress blog.

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.
