XUL and Python

You can use Python with XUL with the help of a http server
which execute plain Python Scripts sent by the client.
Like the following :

JScript .NET + WMI

Finding documentation for using WMI with JScript is not easy.
Compile this code with 'jsc' (shipped with .Net) in an exe file

import System;
import System.Management;

var diskSearch = new ManagementObjectSearcher("Select * from Win32_LogicalDisk")
var obj = diskSearch.Get()
var prop = new Object()

for (prop in obj){
print(prop['Caption'])
}

Les Scripts HTA


Les applications 'hta' sont de simples fichiers html ayant pout extension 'hta'.
Leur intérêt, entre autre, est qu'il sont interprétes par Windows comme de véritables
applications. Ils permettent ainsi l'utilisation de tous les composants 'html' dans les
scripts écrits en vbscript ou tout autre langage supporté par wsh.

Jython - SSH

Ganymed est une librairie java qui implémente le protocole SSH.
Et bien sûr on peut parfaitement l'utiliser sous Jython :-)
Voici un exemple de servlet Jython utlisant Ganymed.

http://www.ganymed.ethz.ch/ssh2/


from javax.servlet.http import HttpServlet
from ch.ethz.ssh2 import Connection,Session,StreamGobbler
from java.io import BufferedReader, InputStreamReader

hostname = '127.0.0.1'
username = 'admin'
password = 'Yu8KL%'

class MonServeur (HttpServlet):
    def doGet(self,request,response):
        self.doPost (request,response)
    def doPost(self,request,response):
        sortie = []
        conn =  Connection(hostname)
        conn.connect()
        isConnected = conn.authenticateWithPassword(username, password);
        sess = conn.openSession()
        sess.execCommand("uname -a   &&  df -k")
        stdout = StreamGobbler(sess.getStdout())
        inputStreamReader = InputStreamReader(stdout)
        br = BufferedReader(inputStreamReader)
        toClient = response.getWriter()
        response.setContentType ("text/html")
        while (1):
            line = br.readLine()
            if line == None:
                break
            sortie.append(line)
        toClient.println (sortie)

Utiliser Jython développer en Java

Jython est l'implémentation en Java du langage de programmation Python.
Il permet d'avoir accés à toutes les classes Java. En outre on peut très facilement
créer des applets, servlets, beans avec toute la simplicité du langage Python: le rêve.

Si vous voulez tester voici un lien qui explique comment par exemple
déployer une servlet Jython sur Tomcat. (J'ai testé cela marche très bien).

http://linuxgazette.net/issue97/tougher.html

Jython inclue la servlet "Pyservlet" qui permet de modifier la servlet et de l'exécuter sans recompilation !!!

Modules musicaux

Je viens de rajouter quelques morceaux de musique. Ne vous arrêtez aux premières mesures :-)
Malheureusement, la conversion au format mp3 réduit de façon notable la qualité du son et des effets. Mais bon c'est le prix à payer.
Si vous désirez en savoir un peu plus sur l'origine de ces oeuvres musicales, je vous conseille de visiter ce site : http://www.modarchive.org.

Bonne écoute...

Impressionnant...

C'est le premier mot qui m'est venu à l'esprit en regardant le travail effectué par Jean-Michel Doudoux.
Voici un site qui ravira tous les utilisateurs du langage Java.
A lire absolument.

Musique en ligne

La diffusion de musique en ligne peut-être réalisée très facilement, comme le témoigne ce site.
Pour ce qui est des fichiers mp3, il existe de nombreux sites sur l'internet qui pemettent de les stocker en ligne, et de les rendre disponible à travers des liens URL.
Personnellement j'utilise : http://www.snapdrive.net

Inauguration

Google, met à disposition un certain nombre d'outils en ligne qui méritent véritablement le détour.
Pour quiconque n'a pas besoin d'un site sophistiqué, ces outils sont amplement suffisants, avec le gros avantage de ne plus avoir à s'occuper du stockage et de la disponibilité
J'ai décidé de franchir le pas.
