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.

Normalmente Gioorgi.com non è un sito dedicato alla illustrazione degli errati investimenti della Redazione. Però l’andamento del Fondo Arancio di ING Direct è così fallimentare, così stupidamente deprimente che ci incita ad una concisa discussione sui meccanismi dei fondi, in modo semiserio.

Poiché tra i fondatori di Gioorgi.com ve ne è uno che ha contribuito al design del backend su cui si basa l’interfaccia di compravendita fondi (=Giovanni), ci siamo sentito molto in colpa quando abbiamo visto questo grafico:

Come si può osservare dal diabolico grafico, il fondo ha iniziato a veleggiare tranquillamente intorno ai 53 euro a botta. Giovanni, da bravo tester e risparmiatore è arrivato ad acquistarne qualche modesta quota, per un prezzo di carico medio intorno ai 55 euro. Ha continuato fiducioso nel mercato anche durante la caduta a picco del titolo, che ha iniziato a verificarsi intorno al novembre 2007.

Poiché il titolo stacca una cedola ogni giungo, il Gio credeva che di lì a sei mesi la bufera sarebbe passata, ma per sicurezza ha smesso di acquistare titoli, visto che la crisi dei mutui subprime stava iniziando a insospettirlo.

After a bit of working, the projects section of Gioorgi.com is coming into life. Gioorgi Team is looking forward the 2009 to finalize the research projects.

Feel free to leave your comments and ideas below, or in the Guestbook at the right.

I am happy to annouce to the world a new website, which will substitute the old Vamp site

It is Gioorgi.com, the italian blog of Giovanni Giorgi.
Gioorgi.com will also spot a new technology "gym" during the year 2009.

Stay tuned!

This article has been retained for hisorical reasons. In this article we refers to blog.Objectsroot.com a site discontinued on August 2008

After some time, I have decided to start redesigning the content and the look of ObjectsRoot.com I have slightly reduced the tags section, over-simplifying the access to my huge set of articles. With over 100 posts, there is no need of so much tags. The search engine will help you to find old articles: do not worry anyway, permalinks will remain valid for a long time!

iPhone is the brand-new Apple product which has changed the way Apple thinks. Because of iPhone, Apple strip the word "Computers" from its brand name. And because of iPods and iPhone products, Lepoard developmenet slip a bit, blurring the focus on pure technology.
To be true, I do not beat on  the iPhone success, but the product success is at least  bright this year. And the iPod touch has also added value to the iPods product catalog. But I am an IT-man, damn you boy! So I want to buy it to play with it, to program with it!

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:

I am very happy to announce my personal annotated Python Search Engine.

 

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.
