Best of this Week Summary 09 February - 15 February 2009

• This week a new web-based online code editor from Mozilla Labs. Javascript, HTML and CSS support are in this first beta release. All made in Javascript and requires Canvas support. One of the goals is to create new useful functionality for the code editor. Check the video for a full introduction.
  


• You can now get your IBM licensed software on Amazon's EC2 AMIs. Development AMIs with IBM software on them are also available at no additional fee. In the future it will also be possible to purchase these services by the hour. Initially available are: IBM DB2, IBM Informix, WebSphere sMash, IBM Lotus Web Content Management, and IBM WebSphere Portal Server. No I'm not sponsored by IBM, but I do think it's a smart move.
  


• RWW is noticing there is a trend towards a different type of databases than relational databases. There's increased interest in key/value pair storage, e.g Distributed Hash Tables. Pros and cons are described. Example cloud initiatives of these key/value storages are: Google's AppEngine Datastore (built on BigTable), SimpleDB by Amazon and Microsoft's SQL Data Services.
  Non-cloud initiatives are CouchDB, Project Voldemort, Mongo and Drizzle (this last one is more or less a mix of the two paradigms).
  


• An application architecture pattern for RIA applications. At the end of the pattern the implementation is based on MS frameworks/tools but pattern is technology-agnostic.
  


• Summary of a SOA case study at Cisco.
  


• A nice set of coding tips for writing efficient Android code by Google, essential for Android since it runs on embedded systems. Still the tips are so generic you can apply quite a few of them in regular Java applications too.
  


• And as the last item for this week: an overview of the expected changes in Java EE 6.
