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.

I have read http://www.manageability.org/blog/stuff/chandler-failure and I think it is very danger way of exposing concepts.

In the article pointed out, the quite dead Chandler project is compared to the multi-billion Eclipse project. And then a too easy analysis is done against dynamic languages, where Java is the absolute winner.

Oracle buys BEA and Sun buys MySql.

In reply,Migrosoft is hungry and is watching Yahoo :-)

<joking> 

Any bets on the next money-based-news?

I'm going for

• Oracle buys Sun: "We need more hardware to run Oracle and WebLogic together! "
  
• Google buys Oracle: "We have *even* more hardware...come on!"
  
• Apple buys Google: "So nice LOGO", retrodating a bunch of stock options, I suppose.
  
• Microsoft buys Apple ("So annoied their are more cool then us!") and shut down all them all so you will end up using their search engine, I hope.

iPhone is a very nice project, well designed and manufactered, but the market addressed is
an hard bet for Apple.
Big players are already on the ground: Nokia, Motorola, Samsung and Sony for instance.

So it is difficult to play in such market, and some analysts said  "the touch screen was not successful for GSM/phone products".

Is it amazing things you can do with a simple Bourne Again Shell  (bash).

I have just discovered you can open socket using a small redirection syntax, and emulate small checks you normally do with curl or wget.

The bash shell manual is always poor about examples, and this is very very sad.

The trends of this october are about some upcoming products. A clear analisys of QuarkXPress failure is sketched in roughlydrafted site. I do not think the same consideration can be applied to Vista.

As Joel said, M$ can throw away much money before only starting to see its market reduced.

Yes this is a negative-advertise (sometimes called flame). I get disappointed by "The Super Dimension Fortres" after about 3 years of use. The service was spartan but quite good, and you got lifetime access for only 36$. I also paid for some additional services from time to time. Then in the summer I launched a "vhost" command, to understand how vhost works. I found no manual and no help, so I closed my shell and went to bed.
After some month, the administrator asked me to pay for a VHOST service I never used. Abeit the time passed, I complain about it sending an email. I recieved NO response.
After a month my account was deleted.
I cannot speak with the administrator. I received only silly auto-generated email asking for money.
And by the way no a decent bill evidence.
This total lack of communication and brute-force resolution of a trivial problem is bad. So I must discourage my friends and readers, to AVOID the Super Dimension Fortres service at all.
