The Long Awaited JDK 6 Update 10 has been released

Here is the link where you could download the latest JDK.

I have heard about this long awaited release, JDK6u10 since the time I attended the Sun Developers' Day 2008, on June this year. Joey Shen presented what's new in this version.

Though the version name seems to be only minor update to the JDK 6, actually this version contains a whole bunch of improvement.

The most notable one explained by Joey Shen is the modular approach in downloading JRE. Now the JRE could be downloaded very fast, the initial will only be download only small piece of jar. Later other components will be downloaded on demand.

Why jump straight away from update 7 to update 10?

I believe these features weren't released as JDK 7 because JDK 7 has been released to the community as OpenJDK in which Sun Microsystems doesn't have the direct control over the release. There were some long discussion on what features should be in, not mentioning also when to release. Inherent problem with community driven release of such SDK is the delay caused by strong disagreement among the community.

So I guess that Sun just put a certain number for the next version, which turned out to be update 10 while we were in the update 5 or 6 just to be safe and give some lead time to complete the job. As there are lots of full timers and experienced employees working on the version Sun Microsystems could be better drive the release of update 10.  Eventually they finished long before update 8 being used, thus the number jumps from update 7 to update 10!

Sun Developers Day 2008 at Singapore

Today I attended the Sun Developers' Day. My office is not in the habit of sending people to such events, so I have to be a proactive person, take a one day leave to attend this event.

"Sun Developer Day 2008 brings together visionaries, leading experts and developers to seize the next wave of technical innovation through Open Source".

Trends that were presented are in the topics of JavaFX, MySQL, OpenSolaris.

This is my first time attending Sun Developers' Day. There were Sun Developers' Day events in Jakarta, but I didn't manage to have time to attend one of them. 

Some thing that interest me are: JavaFX, VirtualBox, new OpenSolaris eye candy, MySQL tuning, and Solaris DTrace, JDK 6 update 10, Grails.

Matt Thompson, manager of the Sun Technology Evangelist group,  gave an opening message. 

Among the speakers were:

Chuk-Munn Lee, Senior Developer Consultant and Technology Evangelist for Technology Outreach at Sun Microsystems in Singapore.

Joey Shen (Zhuo-Li, Chinese), Technology Evangelist for Sun Microsystems based in Beijing, China.

Peter Karlsson, Solaris Technology Evangelist for Sun Microsystems. 

Raghavan Srinivas, CTO of Technology Evangelism at Sun Microsystems.

This even also intertwinned with JavaJive competition final between universities from Singapore, Malaysia, and Thailand. Previously local competitions have been held in their respective countries. The final presentation brought was won by team from Thailand.

Installing Solaris 10 on SunFire V210

Because most of my time, I have spent in the development, this event is considered a rare occasion: a hands-on experience on plain Sun SPARC based 64-bit machine. This time I have it all in my power: SunFire V210. A machine which you could install, reinstall, configure, reconfigure the way you want it.
In my opinion, it was much easier to install Solaris 10 on Sun's machine, than it was to install one on a virtual machine, or even on an ordinary PCs. The Auto Layout Disk went smoothly, no failure is necessary.
This is actually a rather old machine, used to test the installation script. The client doesn't want to go to their client and install the application only to find out that there's something missing in the installation script. So we fetch out a machine similar to the production platform: a SunFire V245. It is of a bigger size (2U, I think) compared to V210 (1U).
