Best of this Week Summary 18 February - 23 February 2008

• Nice overview showing how a Ruby on Rails Facebook application named "Friends for Sale" scaled to handle 200 requests/second and 300M page views per month. Includes the used hardware, software, # of visitors etc.
  


• This is a short article describing Comet, one of the better known technologies to push events from the server to the browser client. Also explains the name Comet (I for example thought it was a software product, not a technology).
  


• Reference to a thorough thesis (conclusions in the article) on performance of AJAX applications for 12 frameworks on mobile devices. Also 5 larger AJAX websites on mobile devices were compared.
  


• Nice (but not very elaborate) comparison of 9 features and benchmark of four JEE 5 servers: JBoss 4.x (OSS), Glassfish 2.1 (OSS), WebSphere 2.0 CE (OSS) and WebLogic 10. Check the reference to the jRealBench (zip) benchmarking tool.
  


• IBM has just opened their Jazz tool for beta. This post is a short description of installing and using it. Jazz "is a collaborative development environment product based on Eclipse, designed to support the application of RUP, which is itself an interative software development process framework built around iterative". But as you can see in the comments, it's not really restricted to RUP.
