Woow it's been a while!

It's been a while since my last post but i am a live ;).

well actually i was very busy those couple of months, woking on several projects (and i still actually). now i am on a project dealing with BPEL and workflow nets and java langage (maybe a little more details later...).

Oracle XE hates the Accents!

I just installed Oracle database express edition (i have some homework to do) and i was surprised that she hates the accents.
The problem:

To keep it sample i use the command line to access oracle server and i just can't use words with accents to create tables:
for example here what i got if i try to creat a table called "évaluation" with two fields "id"(number(2)) and "nom" (varchar2(15)):

The Solution:
well to fix that problem you need to set NLS_LANG to FRENCH_FRANCE.WE8PC850
but how to do that and what is that NLS_LANG thing??
OK first if you need to fix the problem quickly just open the command line and type :
>set NLS_LANG=FRENCH_FRANCE.WE8PC850
>SQLPLUS

and voilà that's it but remember you need to do it every time you open the command line.
Now if you want to know what is the NLS_LANG think you probably want to go there (but it's in French) and you can find some informations from oracle.com about it here and here.

few slides about blogs

A couple of weeks ago i presented a few slides about blogs and blogging in my French course in ENIT (where i study) and i just uploaded the presentation with google docs (i am discovering it) so i hope you enjoy it
Note : the slides are made in French!

So why this blog?

As any student in the world, i am concerned by my career and specifically what kind of skills required to have the best opportunities ? what i should know, learn, master,...?
And one of the great things about blogs is that they help you answer those kind of questions. Actually while writing in a blog you can "see" your hole learning process, and your previous steps. But the most wonderful benefit you get with blogs is definitely the FEEDBACK. Feedback is crucial for any learning process, and it makes you in the right path early, i mean just think about it you have all those experts in a field or another how writing comments(, advises,...) for you!!
There is certainly other reasons like improving my English which is a foreign language to me (as you probably can notice :-) ) but also this blog just get me a chance (i hope) to meet other people, and publish (My) thoughts loudly.
