If you have an application with thousand of beans, you must do unit testing but…Spring testing is boring, belive me. A very complex Spring application usually have a lot of dependency: I had to manage over 3000 beans definitions in a production project right now. Sometimes you want only to test a bit of it, and setting up a complete Spring Context will drive you crazy. To avoid losing mind, my suggestion is to …cheat. Let’see how.

Because of the success of my article on java closure, I have decided to write another article on functional programming.
In the last year functional programming is waving back to us, for a lot of reason. Let’s summarize the facts:
Functional programming is based on the core concept of pure function. The main advantages of functional programming is the lack of side-effects, at least at the syntax-level of the language.

Inversion of Control (IoC) is a very good idea.
But as the clever Joel Spolsky noted, sometimes you need to be a super-natural hero to use it:
… I try not to be judgemental (HAHA!), but I think that people who use IoC containers are (A) very smart and (B) lacking in empathy for people who aren't as smart as they are. Everything makes perfect sense to them, so they have trouble understanding that many ordinary programmers will find the concepts confusing. It's the curse of knowledge. The people who understand IoC containers have trouble believing that there are people who don't understand it. …
I have trouble using Spring in at least two projects. On the third, it was a disaster, because a single software-architect-guy keeps passing around the Spring context factory as method parameter, getting beans from it!

Nei mesi passati ho avuto l’opportunità di lavorare come software architect per un progetto basato su .NET e C#.
Da molti anni non bazzicavo in ambito Microsoft, e quindi è stata una utile palestra. Ho pensato di scrivere questo piccolo manuale per sviluppatori java con la ventura di dover diventare… C#-enabled.

On November 12, 2010 SearchBlox announced the availability of SearchBlox Search Software as a completely FREE product.
I took a look to SearchBlox on a complex project, and I suggest you to give it a try. It is a good solution for small sites, and it is powered by Lucene. Google Mini has a strong brand, but it cost a lot and it had a 2-year resubscription process: a very costly stuff.

How many times have you read or written the same two or three lines of code that frequently seem to go together, and even though they operate on different objects, feel like the same thing? And how often these repetitions involve some sort of collections iteration or more generically manipulation? These repetitions in the code is something that developers eventually learn to filter out and ignore when reading code, once they figure out where the interesting parts are placed. But even if the developers get used to it, it slows them down. Code like that is clearly written for computers to execute, not for developers to read.
Integrate lambdaj in your software architect toolkit (italian link)lambdaj is designed to easily manipulate collections. Its features are intended to filter, convert, index and aggregate the items of a collection without explicitly iterate on it.

Spesso capita di dover scaricare file al di fuori del browser: per esempio per installare software o per consentire ai propri programmi python/java/curl di effettuare delle azioni programmatiche
Se avete problemi con i proxy Microsoft (cosa abbastanza comune, vista la diffusione), su Internet trovate una soluzione:
