Anatomy of an open source cloud

M. Tim Jones at developerWorks has written an articles on the building blocks for infrastructure as a service.
The use of the cloud as an abstraction is quite common for the distributed system that is the Internet, but the past few years have seen this abstraction expanded to incorporate highly virtualized and scalable infrastructures that are easily provisioned as a service (either locally or remotely).

The article begins with an exploration of the cloud architectures and then moves beyond the building blocks to the more highly integrated solutions.

Use jspInit() method to cache static data Initialize the 'out' object (implicit object) with proper size in the page directive. Set the content length Give 'false' value to the session in the page directive to avoid session object creation. Flush the data partly Use StringBuffer rather than using + operator when you concatenate multiple strings Use include directive instead of include action when you want to include the child page content in the translation phase. Avoid giving unnecessary scope in the 'useBean' action. Use print() method rather than println() method Use ServletOutputStream instead of JSPWriter to send binary data Minimize code in the synchronized block Do not use custom tags if you do no...

How old are the daughters?

Two MIT math graduates bump into each other at Fairway on the upper west side. They hadn't seen each other in over 20 years. The first grad says to the second: "how have you been?" Second: "Great! I got married and I have three daughters now" First: "Really? how old are they?" Second: "Well, the product of their ages is 72, and the sum of their ages is the same as the number on that building over there.." First: "Right, ok.. oh wait.. hmmmm.., I still don't know" second: "Oh sorry, the oldest one just started to play the piano" First: "Wonderful! my oldest is the same age!"
