Why Eclipse Europa 3.3 crashes

If you're using the latest release of famous IDE you've surely experienced a lot of problems: every 10 minutes it crashes! Time depends by the projects opened and plug-ins installed.

Today my Eclipse crashed at least 15 times. So it was come the time to fix the problem. After some research I discovered the problem. For a well known bug you had to change the way you launch the IDE.

Change your eclipse.ini in the Eclipse's installation directory to:

-showsplash org.eclipse.platform
-vmargs
-XX:MaxPermSize=128m
-Xms40m
-Xmx256m

If you've a lot of memory try my configuration:

-showsplash org.eclipse.platform
-vmargs
-XX:MaxPermSize=128m
-Xms256m
-Xmx1024m

Your productivity will thanks ;-)

In Memory of Dave Morse, Amiga Co-Founder, 1943-2007

"David Morse, Amiga Computer's co-founder passed away last week. I will remember him always". This is the news found on http://www.rebol.com/article/0345.html.

I never met David. We're part of different generations. But he worked to create one of best my partner of ever: Amiga computer. I started to play with Commodore 16 when I was about 10 years old. It was the holy communion gift of Diego, one of my best friend. I was amazed how can be easy to instruct a machine to make tasks. Then after so much efforts my mother bought me the first Commodore 64. I spent so much time on it... Playing and programming with the bundled Basic and just 48Kb of RAM.

After some year I was captivated by Amiga 500 computer. At that time I was living in Grosseto, a small town in Tuscany, Italy. So much powerful, so beautiful, so much forward than competitors: 4096 colors, true preemptive multitasking operative system, unix-like shell... So I decided to sold my C64 and all stuffs (games, applications, devices, etc.) to have enough money to buy my Amiga 500. I can remember yet the day my mother, my brother and me went back home with the enormous boxes containing Amiga 500 and the Philips monitor 8833 II. Full afternoons up my keyboard after the school. Amiga was my partner for many years until my last Amiga: the Amiga 1200 model equiped with M68030 50Mhz (a monster at that time).

Thank you again Dave, thanks to your wife Lorraine that surely doesn't know how Dave's creation charmed our generation.

RIP,
Luca

Gnocchi on Wednesday

Today is Wednesday. In Italy is not the classic day to eat Gnocchi (it should be Thursday), but today Luigi and Alessandra made an exception. In the interview Luigi told about your Gnocchi recipe: "I simply apply the design patterns on cooking".

Sun Tech Days Italy - Rome

Today I attended the Sun Tech Days Italy event in Rome. By a fast look at the agenda speeches seem to be pretty interesting but in general in this kind of events IMHO the quality is very poor, maybe also for the very short time available for every single talk.

I was wrong. The afternoon was flighted since all talks was very interesting! In the morning, instead, I was in the JUG stand along with Mara Marzocchi. JUG Roma staff is working for the next upcoming Java Day 2007 event in Rome as well.

Below the agenda I attended today:

	Java Scripting: JavaFX Script and JRuby - Sridhar Reddy Much more deeper than the talk listened at Jazoon '07. Today Sridhar talked about the JavaFX syntax language. JavaFX contains very interesting features. One for all the bind keyword that allow to listen changes in chain.
	Java Persistence API: Simplifying Persistence - Sang Shin Sang is a veteran speaker, nice and never predictable. What a shame for no one words about JDO specification!
	Ajax and Web 2.0 Related Frameworks and Toolkits - Sang Shin Sang explained in detail all kinds of Ajax frameworks (Dojo, DRW, GWT, etc.) with some slides and a working demo for every single one!
	Building Rich Web Applications using jMaki and Phobos - Doris Chen Doris fired me the interest for jMaki, what Jazoon's talk didn't! Very cool tool. I'd like to spend a little more time on investigating about the integration with Roma Meta Framework.

Here the full agenda: http://it.sun.com/sunnews/events/2007/sept/jc07

And in conclusion:
- I note down some improvements in Roma based on frameworks seen today.
- I forced me to give a chance to the NetBeans IDE. When? After the release of final 1.0 of Roma Framework, of course :-)

Preview of Release 1.0rc2

For most of you August is a "dead month". Roma staff, instead, worked hardly to complete the release of 1.0rc2. Now you can taste a preview by downloading it from the SVN repository.

Take care to read information about compatibilities issues and migration here:

Ruby on Rails and its Database Driver Approach: back to the past?

I admit Ruby on Rails (RoR by now) contributed to know the convention-over-configuration pattern and now a lot of tools and frameworks are adopting it.

But I continue to hate the RoR's Database Driven approach: Where is the OO model? It seems to be back on PHP/Visual Basic!

Using Roma Meta Framework you start from your pure OO model following the DDD approach. The persistence aspect will convert the model to database. Dot. Let's think OO and the Aspect implementation will do the rest.

SourceForge renamed SubVersion URL of all projects

Just today I discovered the reason RomaFramework's SubVersion repository wan't work anymore since 4 days: SourceForge renamed the SVN URL of all projects inserting the project as prefix.

Before:
https://svn.sourceforge.net/svnroot/romaframework/trunk

Now:
https://romaframework.svn.sourceforge.net/svnroot/romaframework/trunk

The great thing is that you can't find any news about it in the SF.net homepage!

Eclipse 3.3 Europa sucks!

Three days ago I installed Eclipse 3.3, called also as "Europa". Today I'm back to use the previous one since it's much more stable and fast! Moreover the new Eclipse Update Manager works bad since it alerts me about new updates but I can't download and install its from the IDE cause unknown error!

Eclipse 3.3 Europa sucks (for now)!
