• A short overview on what the differences are using Java in Google App Engine (and shortly mentioned in MS Azure) compared to "regular" JEE apps.
  


• Three Java serialization options compared: Java Serialization, JSON Serialization and Google Protocol Buffers. Check also the comments here. Another benchmarking set can be found here.
  The protocol buffers solution was fastest in this test.
  


• The third edition of Mastering EJB, is now available for free download off of TSS as PDF.

• Interesting read on the IT infrastructure (most of the article) in F1 racing.
  Some quotes: "each car has roughly 100 sensors placed in key data capture positions and send anywhere up to 20 gigabyes of data back to the pits during a race."
  "They are collecting four to six megabytes per lap. It depends on the track layout and the quality of the coverage but we transfer about 70 per cent in real time to the garage or the pits". And, did you know there's a connection with the factory during the race?
  


• A funny observation that CSS has quite something in common with Aspect Oriented Programming! Includes a table which shows the similarities.
  

Service Oriented Architecture diagram template

In a past project I had to create a Service Oriented Architecture diagram. Before I created it, I searched on the internet to find a template I could re-use.That I couldn't find anywhere. As next best solution, I used many diagrams as inspiration to come up with my version.

Since I believe in re-use, I wanted to share my knowledge and give others a headstart by providing the the diagram I created online. The actual diagram from the project I couldn't use, so I recreated a new diagram from scratch. Below you see the final version and a link to the editable(!) actual .odg document you can download. It has been created in OpenOffice 2.1 Draw.

The diagram is free for you to use, just as long as you refer to were you got it from: http://ttlnews.blogspot.com/

And this is the link to the actual document.

Hope you find it useful. Comments/feedback/tips are of course welcome too!
