Having acquired a ReadyNAS duo for my new backup system, I wanted to explore the system that runs on it and see if I could run more services on it. There is nothing terrific in this article as many people have already done this before. Anyway it describes step by step what must be done to connect to the ReadyNAS.

Inserting a file in a JSF view with a custom component
By Stephane Carrez on Monday, January 26 2009, 21:56 - java
My problem was to give some flexibility in a JSF page to customize some blocks so that a marketing team could easily change those blocks. Basically the marketing team needs to insert some promotion, advertising or specific presentation blocks. For this, they ask a designer to make those blocks. The designer will give us some piece of HTML (with Javascript) that must be inserted in the page.

Viadeo passwords are not secure: can you trust web 2.0 applications?
By Stephane Carrez on Thursday, September 11 2008, 21:14 - Security
We are using more and more Saas applications available on the Internet. Social networking applications like LinkedIn, Facebook, Plaxo are quite famous in the world, Viadeo is well known in France. In all these applications that you use, you have to authenticate yourself (this is a good thing). In many cases, you just have to give an email and a password. What confidence can you give these applications? Can you trust them? Are they secure enough?

Restoring a complete system after a hard disk failure: bacula to the rescue!!!
By Stephane Carrez on Saturday, July 5 2008, 13:41 - Linux
Last day the main disk of by computer stopped to work. My Western Digital 150Gb raptor hard disk was no longer recognized by the system: it was simply dead after one year of work. The 10000 rpm disk contained the Ubuntu 8 system, my home directory with all my files and other important critical and important data. When this kind of problem happens, you don't care about the 3 year warranty of your disk, but you are very thankful to the backup system that you put in place. Indeed at the end of the day, you will only have lost some time but not your critical data. Here is how.

Death match: Windows Vista versus XP
By Stephane Carrez on Wednesday, April 23 2008, 23:35 - General
I'm amazed to see people speak about Vista as the Saint Graal of operating systems. Is it worth to upgrade? Many people will not ask the question and will jump to it with closed eyes. Take care!!!! You should better think twice before the upgrade (this is true for every software in fact). The article written by Randall C. Kennedy, Death match: Windows Vista versus XP, is interesting in drawing the most important reasons why you should stay with your XP version.
I'm also amazed upset to see that in 2008, a Microsoft Vista running on a 3 Ghz CPU with 2Gb of memory does not bring anything compared to an operating system from 1998 running a P3 350Mhz with 128Mb of memory. 10 years of serious hardware progress. Big regression on the software side.

Deploying a J2EE application behind an Apache server in a production environment
By Stephane Carrez on Sunday, April 13 2008, 12:35 - J2EE
You have created a Web application using a JBoss application server and you are going to put it in production. Great!
But deploying your application with JBoss serving the Web requests directly may not be the optimal solution. First because the Tomcat web server embedded within JBoss is not the best server to serve static files and second because configuring Tomcat and JBoss for best performance and security is in general a complex and tedious task.
Instead, it is a good practice to use an Apache server (2.0 or 2.2) in front of your JBoss/Tomcat. This Apache server can serve static files, take care of your SSL security and manage for you all the details of HTTP headers (Expires and other headers) and more....
