At Gioorgi.com, after working with a lot with software for over twenty years, we have envisioned a clear idea about open source. This is the first article of a series tagged “opensource”: let’s start!
Richard Stallman Vision, based on GNU open source idea, is too radical from our point of view.
Stallman GNU License is based on a “copyleft” idea, which gives everyone the freedom to look at others’work, without taking credits for it. The license vision is very strict, so consulting is the natural option for an IT business based on GNU software, which is drived by Univestities, because of its basic freedom statement. Closed and paid software is still widely used, but open source is the key for the next revolution; let’see why.

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….

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.

The Network Computer was a bad idea born in the middle of the ‘90, and ended up to be completly wrong. Anyway, the current software tecnologhy (like AJAX, Google Gears, the psedo-new-ms-windows os called midori) can be helpuful to sketch a new idea of operating system.
The network computer fails because it pretends to store all information (program, user data) on the server. Worst, it pretends a fee for application usage. But users preferred a buy-one model, because they didn’t like the renting model
In the NC world the Software company will also hold all you private documents, a very security concerns.
And the software company must guarantee also nobody will look your important market strategy stored on a corel draw excel. This things costs too much.
Even Apple is trying to remove DRM from Apple Store, selling some titles without it. The reason is simple: apple needs to upgrade its copy protection scheme, for avoiding some hacker will be able to crak it. But this costs too much!
Let’s see what we can think now, after 10 years, a bunch of iPhone/EEPC out of there and Open Source full of life…

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.

As some of you know, I was a Smalltalk fan&developer in the last twelve years. I have stopped working on smalltalk years ago… anyway, I am happy to look forward the Squeak Smalltalk Community from time to time.
I republish here an original article posted by me on SqueakPeople, over 4 years ago. The reason is simple: I am very happy to see a Squeak code fork called “Sapphire” which share most of my thoughts:

Per un importante cliente di ValueTeam, ho sviluppato per un'applicazione chiamata PDFGenerator, che è stata pacchettizzata come un vero e proprio prodotto.
PDFGenerator nasce in una situazione caratterizzata da un alta variabilità dei requisiti utente.Le specifiche del progetto hanno subito variazioni significative nell'arco di quattro anni, ed alla fine i requisiti utente erano parecchio mutati. L'applicazione, già fatturata, non era ancora stata validata dal Cliente finale, ed era passata di mano moltissime volte.
Da un lato c'era la necessità di fornire uno strumento semplice da utilizzare, dall'altro la possibilità di espanderlo nel momento in cui le esigenze di Business del Cliente fossero cambiate, contenendo i costi di sviluppo.
Questi due aspetti erano acuiti in questo contesto, poiché i dati potevano provenire da fonti assai eterogenee per tipologia (database o personale del marketing) e l'utente finale doveva elaborarle in modo uniforme e rapido.
Per queste ragioni la specifica era cambiata spesso nel tempo, e la sfida era notevole.
PDFGenerator è semplice dal punto di vista software, e la sua forza sta nell'idea, e nella capacità di capire l'utente finale.

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.

In the last year, "Apple Computer" has changed a bit its focus.
First of all, Apple has erased the word "computer" in the company name.
Then, has shifted its focus on new products like the iPhone.
iPhone is a GSM telephone, and so it is quite different product for a computer company.

There is a future for SmallTalk? I was a very strong fan of the SmallTalk language, but in the last five years I have seen more and more contraction of its usage in the IT field.
The OLPC project, which uses also Squeak Smalltalk and its done by the core team fo Squeak, is not going very well.
