Why this guy hate frameworks?
This is a funny and very interesting post about frameworks and, I think, overdesign in software development from Benji smith

Simple UML diagrams with UMLet
UMLet it's a nice tool for drawing Sequence and Use Cases UML diagrams. It's very simple, intuitive and also funny to use.
My favorite features are the edition of artifacts based in plain text and, mainly, that it's no a pure UML tool, you can draw not fully UML compliant diagrams, and this can be very useful (sometimes)
I think it's a fantastic tool to draw simple and descriptive diagrams rapidly. Of course it's not CASE tool, but also it's cleaner than use a blackboard
UMLet runs as Eclipse plugin, and also as standalone application. Try it!

RIA Frameworks
Althought traditionally I have not been working extensively in User Interfaces, and of course I'm not an expert on this area, I'm pretty sure that somethings goes wrong in traditional Java web interfaces development (Struts, JSF, Spring MVC).
It's too hard develop a Web application, too much code, too much errors, too much programmers!
I'm not sure about the future, but RIA interfaces (Ajax or Flex) in Service Oriented User Interfaces (SOUI) seems more razonable approaches.
This is a very interesting presentation about RIA (focuses in Appcelerator framework) from Matt Raible

Viewing CHM files in Mac OS Leopard
Unfortunately the very best operative system in the world, Mac Os X, version 10.5 (Leopard) doesn't have native support for viewing CHM files.
But I found a free and multiplatform application, xCHM that opens these kind of files with a clear interface.
Thanks to David's Logbook

Generating code from code with Eclipse JET
In my current project we need to generate two kind of artifacts, some Java classes that represents bottom up Web Services, and very few XML, the Axis2 descriptor to expose these services.
I admit it, XSLT engines scares me! I've been looking for solutions and it seems that the best approach are template engines. The code to generate is very simple, but i want an MVC approach. I can generate XML with standard apis, using java.xml.Transformer but i didn't found a similar approach to metagenerate Java with a predefined view and controller. Anyway it would be two different apis to manage.
A Template engine is a unified approach for the two artifacts generation, it generates a output based in a template in a language which works with the model.
The template language is the main difference between Apache Velocity and Eclipse JET. Velocity seems more powerful but JET has the advantage that the templates are written in JSP syntax. The other main advantage is that is integrated in Eclipse IDE environment to generate a Java class from the template that performs the transformation, so you can use the template "compiled" in a standalone environment.
As JET is part of Eclipse Modeling Framework EMF, you can use in combination with an EMF meta-model, but we are not going to use this feature.
The next release of JET, JET2 is included in another Eclipse subproject, M2T and it will include new interesting features like JSTL tags and a powerful visual editor.
As there's not a stable release of JET2 and for our requirements version 1 is capable and runs with our Eclipse version we are going to use the stable release.
If you want to start with JET (version 1) these are two fantastic introductory resources:

Why a blog? Why in English?
Well, this is my first entry, at least the first with text.
Why a blog? I've been heard about them, and it seems cool!
I would like to start talking about Software Development,Architecture, practices, and then, we will see.. and i'd like to improve my English too,
So, sorry for the posible mistakes!
