Siamo lieti di dare risalto alla seguente iniziativa, chiamata All4Web, che si terrà l'8 maggio prossimo venturo:

All4web nasce dalla collaborazione di alcune community e user group del panorama italiano del web. Le community e gli user group sono i luoghi dove persone, con una passione e competenze sopra la media, si confrontano e trattano i più disparati argomenti in ambito IT e Design rendendo questi spazi, seppur virtuali, unici nel loro genere. Partendo da questa consapevolezza l'iniziativa vuole essere un momento dove raccogliere nello stesso luogo realtà diverse per trattare argomenti trasversali, multi disciplinari senza per questo precludersi la possibilità di affrontare argomenti specifici delle singole realtà. [...]

La partecipazione a all4web è gratuita. L’evento è realizzato in collaborazione con il Dipartimento di Informatica dell’Università di Milano Bicocca che ospita la manifestazione.

=== JRecordBind ===

A tiny and super fast library that aims to

• map fixed-length lines to bean instances, ready to be chewed by an import procedure (Unmarshaller)

• and export record beans into a fixed-length file (Marshaller).

take al look to it at jrecordbind: Home. It is a very good library, I will suggest for solve these issues, because it has XML integration too

April (Application Performance Framework) is a super-light application framework based on Spring, featuring:

• An Aspect Oriennted Programing Performance Monitor, which try to increase performance on the fly
• A super-light XML-RPC communication framework

April first commitment is “be lite, be pluggable” and do not re-invent the wheel. I am happy to describe here how it works the Beta 0.2, called “Fat Cat” by friends.

The Gioorgi.com’s Knowledge Base is a new service provided to readers.

The Knowledge base arranges tips & tricks scattered on the web, and based on the Giovanni Giorgi’s  IT consulting experience.

The information are mostly based on open source technology, but also commercial products are described. Albeit knowledge base born as a small random “basket for notes”, it is an ideal place for comments, discussions on arguments and so on.

I am not a big fan of portal software, because it is not cheap to delivery.

Portal specification is heavy to use and implement, and can have a reason only in very big corporate company.

SingleSignOn can be delivered in different and simpler way.

The big advanteg of the Portal is the ability to “deactivate” specific unstable feature on the fly, with also the ability to aggregate remote data (remote portlet is one of the key of the idea behind portal specification).

Nei precedenti articoli abbiamo visto come creare un applicazione Java agile, evitando il blasone delle specifiche J2EE. Dopo aver valutato (scartandola) una soluzione 2-tier molto simile a quelle fattibili in PHP, ci siamo focalizzati su una soluzione basata su Spring.

Come test, abbiamo sviluppato a Gioorgi.com una applicazione didattica che abbiamo chiamato “April”.

A Gioorgi.com abbiamo una sezione di ricerca e sviluppo, dove abbiamo la necessità di provare diversi tipi di ambienti in situazioni live: prova e ti riprova, abbiamo consolidato una certa esperienza in soluzioni Java Enterprise a “consumo ridotto”.

In questa serie di articoli (di cui state leggendo la seconda puntata) vediamo come ottenere un’ambiente Java leggero, LAMP-like che gira in una manciata di Megabytes…

Introduzione

Quando Java nacque nel 1995, aveva parecchie frecce al suo arco, ma anche molta incertezza. Ricordo che in università fu accolto con favore dall’ambiente accademico, per le sue spiccate doti didattiche.

Java era più semplice da insegnare del C++, e aveva una libreria di base molto ben organizzata. Era già previsto l’uso della proto-annotazione “@deprecated” perché Sun sapeva che avrebbe dovuto far evolvere l’API, e questo evidenziava la cura e l’attenzione per l’organizzazione del lavoro del project management. Ai tempi Sun puntava sulle Java Applet e sugli aspetti di sicurezza, in cui Java eccelleva. Benché la vocazione di Sun fosse enterprise, ancora le specifiche EJB erano al di là da venire.

L’osservazione dei miei colleghi più scafati, che usavano PHP e Perl er ache Java era troppo pesante (in termini di memoria consumata) e lento (essendo interpretato) per i piccoli microcomputer da 12Mb che affollavano le nostre case.

Nel 2009, quattordici anni dopo, le cose sono cambiate e ora anche i pc di casa hanno sistemi a due processori e 4GB di RAM. Java è ancora lento e pesante ?

Vediamo come sviluppare applicazioni leggere e compatte in Java…

Tired of prepared statement written down on the code?

Tired of Hibernate, and willing to come back to crude SQL debugging?

No problem, dudes!

We tried Elvyx, a  JDBC probe, without a full success. Our quality vote is 5, because of the following bad aspects:

• Very poor documentation. It is unclear if timings are returned in milliseconds or in seconds: no word about it!
• Returned value are often inconsistent, so we cannot use it very well.

Anyway, for a "quality oriented" sampling of data, for finding out most used calls and so on, Elvyx can help a bit.

Happy Friday Hacking!

After my past experience with bad hosting provider, I am happy to say I have find a very good hosting service. If you need VPS hosting, Rimuhosting is a very good choice.

After about two years with Rimuhosting, I can summarize their feature here:

• They have a very good  entry-price for a virtual hosting
• System aministrator has a very prompt response: on every issue I get support in 24 hours, also on Sunday
• Rimuhosting uses a Xen virtualization mechanism which is very effective. I have tried other virtualized solution, which are worst.
• Java hosting works well, without problems.
• The default Bandwith is very huge (30GB). There is also  an automatic backup and a remote web-based shell out-of-the-box.
• You can choose between high-end Linux distribution  (like Red Hat enterprise) and free one.

Hi Sunday!  How are you deare reader? If you are up at 7 o’clock (the publish date of this post), you are probably a very hard rock internet-surfer. And the strong surfer are IT Geeks often.

So we want to give you a small link: a collection of very userful and nice wordpress plugins which should work also for WordPress 2.7. This set is nice because they are small, neat and easy to use, and well organized.

As you know, U.S.A. is having a very bad time, the resulting effect is a “big credit crunch”. For this reason big company operating in the IT are cutting down their minor services. Google is famous for having pushed a lot of “beta” services, and now the company is reviewing its decisions. Orkut (the Facebook-clone until Facebook acquisition…) is one of the service facing a lack of interest by BigG. We can read below the story of a guy who had its credential stolen by a set of smart hackers:
