With one company (IBM) jumping off the merger train another big one joins the game: ORACLE. I guess at this moment no one can really judge if that is the better choice or not, neither would anyone be able to foresee what exactly going to happen to “our” (as in OpenSource) Java, MySql, Netbeans, JavaFX,…
For the last few hours news IT websites, blogs and forums in the IT world are rapidly filling up with news, opinions and rumors about the big deal which definitely will impact the IT world.
Some news summary from JavaLobby (link)
If you are wondering about this and use Worpress, is that easy:
Anywhere in your text you place
[ sourcecode language='java' ]
your sourcecode goes here
[ /sourcecode ]
Remove the space before and after the bracket character to make it work.
your sourcecode goes here
I was recently ranting about a missing Singapore Java User Group. There is some information about previous groups but they appear dead. I try to start a new one… I considered to use meetup.com but I am not really willing to pay money for this. Sorry.
I am not a Java Guru or expert, but that wont stop me to organize something.
Netbeans Wiki Info
The SUN Techdays (20.22 Jan 2009) would be a good starting point.
I started my first project on Sourceforge.net, project title UUIDgen (link). The very simple Java Swing application creates UUID’s on demand. Not really a big deal, since the basic packages are ready available in Java SE. Gather some experience with the process of creating releases, documentation and maintaining sourcecode in the open source context. Feel free to download the first release (requires installed JRE) or get the Netbeans 6.1 project.

While browsing some old email I came across this one. Some relative send me a programming assignment task to be implemented in Java. It is a one page rough description of the requirements. The funny part is, that a lot of times serious, or real world-, software modules are planned in the same fashion. Sometimes the initial spark gets scribbled on a napkin in a pub, sometimes I get requirements from customers with less text as well ! So, in a way, everything starts with this, its just a matter of your methodology if its going to take off towards the CMM 5 heaven or get lost in compilation with spaghetti code.
Unfortunately I dont know about the result of the below task
The international conference on Java Technology hosted in Zurich, Switzerland. It will take place from June 22-25 2009. More info at link
(Has been a while since my last post, but I just enjoyed my vacations and been hardly online at all)
Some upcoming conferences in Singapore to highlight:
JAX Asia 2008 - Enterprise Java and SOA, 25.11.2008 (link)
IASA - IT Architect Regional Conference, 10-11.11. 2008 (link)
I am sure everyone of us had the requirement to save data in a DB, a hash or whatever. Most of the times we were creating this unique numbers, often used as keys for reference, by ourselves simply counting +1. Sooner or later we realized, oops I used the number already or I need to merge tables and now we have duplicate ID’s and so on and so on. Most DB offer some auto-increment feature or you make use of the row-id as oracle create one (internally for each record). I came across the UUID (wikipedia link), which is a universal unique ID creation method. In Java its damn simple to create one:
UUID uID = UUID.randomUUID( );
I worked once for a company which used long integer as their ID field. The max value is 2,147,483,647 and recently they hit the limit facing the problem of hardcoded long integer all over the sourcecode and DB. I guess the UUID would help (using it from the start).
Remark: Putting in a lot of brain power they fixed the problem without refactoring about 1 mill lines of code.
With the help of 122 significant bits in a version 4 UUID you can create 2^122 (5,316,911,983,139,663,491,615,228,241,121,378,304) numbers ! Enough for the lifetime of this universe !
Milestone 2 is released for download. Quite some new features in this release that should hit the release version by October this year. For the average Java programmer maybe no big difference in functionality. I am wondering why they put in so much php functions.
Anyway, here link to the detailed new features and link to the download.
One day someone might look back and want to see where we started:
Java JRE 1.5.0_08-b03
Java JDK 1.6.0_05
