This explains why TwitterSync has not been working the past week.

Quoted: That's the difference. The Twitter app uses the Twitter API while TwitterSync uses IM - if IM is working, TwitterSync is faster and can update more often.

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.

Quoted: However, it is also an extremely simple piece of software: all of the logic is client-side, there is no security model, failover, backup mechanisms, or persistence (albeit the last one is in the roadmap). But that hasn't stopped the developers from deploying it in all kinds of environments, and here are a few best practices suggested by Brian:

Some of the referenced blog posts are quite interesting, too.

Quoted: There are interesting posts these day about future of MySQL Replication by Brian Frank and Arjen. I think it very interesting to take a look at a bit bigger picture using framework from Innovators Dilemma and Innovators Solution.
...
All these requirements made traditional databases irrelevant for many web properties - too complex and too expensive to start with.

You can use this w/mysql to enable automatic recovery when a master fails.

Quoted: Heartbeat works like this: you tell Heartbeat which computer owns a particular resource (which computer is the primary server), and the other computer will automatically be the backup server. You then configure the Heartbeat daemon running on the backup server to listen to the “heartbeats” coming from the primary server. If the backup server does not hear the primary server’s heartbeat, it initiates a failover and takes ownership of the resource.

Looks very cool -- potentially better than the 'for pay' product (ServersCheck) that we are using now.

Quoted: ZABBIX is an enterprise-class open source distributed monitoring solution for networks and applications.

Quoted: In recent presentations I have been demonstrating how Amazon Engineers are scalability experts who can take any concept idea and turn it into a service that can serve hundreds of customers and then grow it seamlessly to support hundreds of millions of customers. In the Amazon world there is no such thing as a limited beta; everything needs to be production quality when it launches and scale in every possible dimension. Incremental scalability is a key fundamental concept in all of our designs such that we can handle growth reliably and cost-effectively.

Technorati went down. The humorous message..

Quoted: The Flying Spaghetti Monster has arrived and we have all been taken to planet Zeus 94 to kneel before Zod. All this is a little much for us to handle at the moment so come back later please. And leave a quarter in the collection tray on your way out.
