I was really happy to see that the event was crowded, it means that Opensource is becoming mainstream also here in Italy.

As scheduled I delivered my presentation on Puppet and OpenJCloud, a set of practices and opensource tools that enable cloud like infrastucture based on RHEL and JBoss. And of course I had some trouble with the microphone…

I also had the opportunity to have a nice chat with Sacha Laborouey, JBoss CTO, about Grails and some development about that.

See you next year

def host = new Ghost(“barman.byte-code.com“)
def result = host.ls()
println result

think about it carefully… do you think it’s possible in less then 10?
Let’s pull out a groovy solution!

The server:

1:import groovy.net.xmlrpc.*
2:import java.net.ServerSocket
3:
4:def server = new XMLRPCServer()
5:def socket = new ServerSocket(8080)
6:
7:server.executeShell = { commandArray ->
8: def p = commandArray.execute()
9: p.waitFor()
10: p.text
11:}
12:
13:server.startServer(socket)

And the client:

1:import groovy.net.xmlrpc.*
2:
3:class Ghost{
4:
5: def hostProxy
6:
7: Ghost(host){
8: hostProxy = new XMLRPCServerProxy(“http://${host}:8080“)
9: }
10:
11: def callCommand(methodName,params){
12: def commandArray = []
13: commandArray << methodName
14: params.each{ commandArray << it }
15: hostProxy.executeShell(commandArray)
16: }
17:
18: def methodMissing(String name , args){
19: callCommand name,args
20: }
21:
22:}

I’m just amazed… this is what I call next generation devlopemt: based on solid foundation of good java libs and move foward on top them.
I don’t think this a full “production-ready” implementation but..it works!
and they’re less the 10 line of code if you remove the “bloat”… half an hour work, a fullblown coffe break application!

Repeat… less then 10 line of code!

Happy groovin’ , keep DRY and write less code that do more;)

as “usual” in the sunny Florida is raining;) and yesterday we also get a “funny” tornado alert!

Anyway we managed to get to our first conference JBoss World. And the hotel is whaoooo! Soon you’ll see some shots on flikr!

I’m now attending @ “Leveraging Ajax and Metdata for Hoc-Reporting” from a Penthao guy and it looks promising(even if the slides are graphically horrible…), I will give you a brief review of each speech I will attend.

given some requests I publish a classresolver for Wicket that enable groovy pages & components to be hot reloaded in development mode.
I suppose you have a project with maven and so let’s start…

1. Get the “mighty” GrovvyClassResolver
2. (fix up the package)
3. Open the WebApplication class and do something like that (remember that I use maven & jetty for dev, If u have a different project structure change the path of the BASE_SRC constant pointing to your source dirs)

   1. 
      
      /**
      
       *
      
       * @author Byte-Code Srl 2004-2007
      
       */
      
      public class GroovierWebApplication extends WebApplication {
      
      
      
          public static final String BASE_SRC = "src/main/java/";
      
      
      
      
      
          protected void init() {
      
              initSpringContext();
      
      
      
      
      
              getResourceSettings().setThrowExceptionOnMissingResource(false);
      
      
      
              String configurationType = getConfigurationType();
      
              if (configurationType.equals(DEVELOPMENT)) {
      
                  getResourceSettings().addResourceFolder(BASE_SRC);
      
      
      
                  getApplicationSettings().setClassResolver(new GroovyClassResolver(BASE_SRC));
      
              }
      
          } }

4. You’re done! Now you can develop in wicekt using groovy & hot reload pages and components.
5. As a side note remember to create a production profile so when you deploy the war the groovy class are compiled and you won’t loose any performances!
6. Ok, now you have to transfer some bucks to my account… or it won’t work!

Ok, that’s all folks, if u have problem just drop me an email!

I’m looking forward to give you a live coverage of the events form the states, so stay tuned between 10 & 24 feb !

Take it Grails-1.0-RC4

Fast startup:

1)Take it (http://people.byte-code.com/dpanelli/grails-1.0-2.noarch.rpm)

2)rpm -Uh grails-1.0-2.noarch.rpm

…and you should be on Grails!

Have fun!

http://grails.org

Now the docs looks great and I’m looking forward to have the final version!

• 90% of “ordinary” programmers, just trying to do their work(hopefully…)
• 10% of “extraordinary” programmers, they want to lead and demonstrate that they’re faster,clever, better, anything ${whatyouwant}er

So the “e” leads the development community finding “genius” solutions, by doing black magics frameworks, and they are passionate, and thats is a good thing… but this produce what I call the Inverse Frameworks Factor! 90% of the frameworks are for the 10% of programmers… and ,you know, given the previous division of programmers..(no, I’m not going to list them all…)

That’s not secret… Think about how many projects you have seen messed up by the complexity of the problem and how many by the complexity of the “not-so-usefull-but-cool-enterprise environment”.  What are the results?

Few days ago I’ve tried the new Netbeand 6m10…. and what can I say? They need more stability(it crashed a few times….) but they are going in the right direction!

It’s a really good piece of software! They are copying all the IDEA completions and code hints and the general feeling of the ide is much idea-like! And that’s great.

I f you are using Idea, have a look at the last vesrion of NB. You won’t be disappointed.
