2.5 tiers, SOFEA and SOUI
- 2.5 tiers name is technically not very precise, but IMHO much more evocative.
- I don't think there will be space anymore in the future for Adobe/Java/whatever based RIAS (Flex or JavaFX), the irect Javascript approach on the client is becoming mainstream, much more easy to code/debug than before, and without losing crossbrowser-ness
- Completely agree on the Front-Controller being an anti-pattern now

2.5 tiers at Javaday 2010
This year at Javaday I'll be happy to present a talk on what I see as a new emergent approach in Web Development. It's not a completely brand new approach, but it's slowly gaining momentum since a couple of years. I couldn't find a good name for this approach, so I invented a new one, "2.5 tiers".
The 2.5 tiers approach is about how Jquery and Rest are changing the way we design webapps: there is no need anymore of complex server side MVC, because you can easily do all the work in javascript, with the help of unobtrusive cross platform Javascript libraries like JQuery.
RESTful design is the other side of the coin, because producing JSON representation of data to be consumed by Javascript is now as easy in Java as in higher level web scripting languages, mostly thanks to libraries like RESTEasy (which is a powerful JAX-RS implementation).
The name 2.5 tiers shows that it's not anymore a full 3 tiers, but it's neither an old client server app (2 tiers). You still have code on the server: caching, validation, REST services, JSON transformation are all on the server side. But a lot of code is now moving back to the client: gui widgets (Jquery UI) are completely client side (probably feeded by a server with JSON) and that's hardly news, but templating for example (JTemplate is one of the emerging libraries) is far less common on the client side. So it's two tiers and "a half".
An interesting side effect of this approach is that you are free to choose for example a .Net application server instead of a Java one (don't take that as an advice!), or try something new and cooler like Erlang or Scala, without touching a single line of GUI code: you basically only have to implement the same interface (GET, POST, PUT and DELETE) and produce the same representation of data (mostly JSON, but XML still has its role sometimes). That means, yes, you can write cross browser components (independent by server side code too!) and reuse those components in other departments of your company that use different technologies (if you are like me, in our company we basically have all the existing IT architectures of the world).

Getting rid of Wordpress...
Here it is what I did:
1) I exported my wordpress blog. You have only to login to your WordPress account, navigate to the Dashboard, look for the Export link. Wordpress will produce a WXR file (Wordpress eXtended Rss) which you will be able to save to your local machine.
2) Go to Wordpress2Blogger, browse the saved WXR document and click Convert and save that file to your local machine. This second XML file is a blogspot specific file.
3) Create your blog on blogspot.com and choose the XML export file you just produced in the Import Blog Tool. Alternatively if you already own a blogspot blog, go to the panel, choose the "Settings -> General". On the first row, immediately before the "Title" filed (yes, it's just a little hidden) there are import and export links. Just click on import and you will see immediately all your old posts and comments
4) After creating my blogspot blog, I wanted to integrate in my site, using my domain name and my look and feel: to do that I just configured the great Rapidblog plugin from Loghound software in my Rapidweaver project. You basically only need to give the blogspot username/password to the plugin.
Et voilà, a complete blog migration in less than one pomodoro! Bye bye wordpress.

Da Java a Logo...
Però qui potete trovare il materiale del corso di programmazione che ho organizzato per i bambini della scuola elementare Maurizio Poggiali, in via Benedetto Croce. Per rendere il post minimamente più interessante, con antlr sto anche cercando di implementare un interprete migliore di quello scritto "a mano" in kde. Ovviamente tanto non lo finirò mai, ma questa è un'altra storia :)
