At Gioorgi.com we will start a series of articles about bug tracking. As usual, our posts will be short, tight focused and open to comments and improvement.

A software will be full of bugs at some point of its life, and every good developer/project manager must be ready to address these issue. Let’s see how to fix them….

Here you can find my Squeak Tutorial for Java Programmers.

I have written it for my friends and for all java guys out of there

[UPDATE] Smalltalk For Java Programmers PDF is available at this url

In this article I will introduce you to Hibernate 3 persistence framework. This article is worth to read, because give you a very fast track to Hibernate; I have used this tool for the past six years, when only the good 2.x series was out of there. Then I have the lucky of training two teams on two different and big projects, with a “zero time” to teach them hibernate. So I decided to put here my advices, hints, tips and tricks, for the rest of the guys around the World.

In the last seven months I have the need of sketching a bunch of interfaces, but I cannot find a valid tool. I was a Software Architect of a big huge project, busy also on other smaller projects as project manager.

I need a rapid way to sketch use cases, to pass them to a very young team.

Web interfaces are not easy to design, and we was in a very weird situation: the team was forced to use DAOs, with no O/R mapping tool. So I need also to map some interfaces to a database model, to help them building the model and the view classes

After some search, I ended up with MS Visio.

MS Visio is great, but too difficult to use, doing training is hard and so I must discourage its use. Worst, Visio costs a lot, and it is not included with the standard MS-Office Tools.

Visio offers only WinXP look&Feel, which is not the best for designing agnostic web interfaces.

Thank you to a friend of mine, I have the discovered the BalsamIQ Mockup project. Let’s see why it is a so good solution.

After a bit of work, I have managed to optimize the performance of my Postgresql Server.

I have spent a saturday morning digging around postgresql, using the fantastic komodo editor, and I am happy with the final solution.

I followed  some suggestion on power PostgreSQL site, and now my postgres is blazing fast. For small needs, tuning postgres is easy as working with MySql. And with postgres you get for free Transaction and PL/SQL without the need to do extra configuration or tuning or your database.

If you need to work on cluster, is nice to have syncronized terminals to send the same commands in parallel.

Is it also doungerous, so do some test before sending a bunch of vi commands!

On Unix, a cheap and fast solution is Kde “konsole” which has such option.
