sun tech day singapore 2009 - Day 1

I was at the sun tech day 2009. 20 Jan 2009
Very fruitful day indeed, being introduced to various
upcoming technologies, trend and tools for developers.

I spent most of time at Enterprise track. Very briefly i picked up the following:

• GlassFish, heard about it, today i get to see how it works. Features like call-flow monitoring for developers -- which container is more time spent?
  

• The concept of Comet ---- instead of typical client ---request---> server. We have for client <---events----server.
• Why GlassFish ? You get enterprise features at open source!

• I get an idea what's DTrace is all about briefly through the track. DTrace is only available on Solaris. In the process of debugging we go through the stages of :
• hypothesis->instrumentation->data gathering->analysis->....cycle repeats.
• DTrace eliminate the instrumentation stage. With as many as 50,000 probes.
• Got to appreciate the D Dynamic Language

• Java FX, sounds like Flash MX, get to lots of rich interactive media.i am keen to find out how i can use it for mobile phone.
  

• I am amazed by zembly. Widgets, Service and Application.The key chain, clone feature are useful. Somehow found widgets and application to be similar.
• Connecting the World with REST => Representational State Transfer. Tenets.

1. Give everything an ID - URI
2. User standard HTTP methods, so that it is cacheable
3. Links things together.
   

• MySQL: Database for Web 2.0 --- I learn alot about storage engine. And the 'EXPLAIN' syntax which is very useful to observe what's happening.
• Groovy and Grails --- have not use it, got a feel of it.
  

• Won a Wii in the referal lucky draw, awesome i can do some development work with Wii =)
