ORA-00001: unique constraint (METALINK.SYS_C005417) violated
This is a partial screenshot of an application without a decent error handling.
Do you recognize it?
It goes without saying that no further comments are needed…

New Infrastructure
This is just a short note to point out that I just moved this site to a new infrastructure (new hosting provider, new Wordpress version and new MySQL version). If the migration went fine, nobody should notice the difference ;-) If you have any problem, please, let me know!
For a couple of days (i.e. until all DNS are updated) I expect hits on both sites. Anyway, if you see this post, you are on the new one.

No Space Left on Device
Some of you probably noticed that this site had some availability problems during the last two days :-(
For that I have to thank “my” ISP. Somehow a disk was full and, of course, some services didn’t like that at all! Anyway, now it seams that everything is up and running. I really hope that this is the last time that something like that happen.

Never Say Never
Only a couple of years ago, I would never have thought I would start blogging. But, you know, as Forrest Gump’s mom said “Life’s a box of chocolates, Forrest. You never know what you’re gonna get.”
So, here I am… the first post…
Sticking to the topic “Never Say Never”, I would like to share with you how I ended up in this business. In the early nineties, I was a student in the department of Electrical Engineering at the Ecole d’ingénieurs de Fribourg. In my final year, I specialized in computer engineering. As a result, my professional interests were related to micro controllers and processors, operating systems (mainly Unix) and C/C++ programming languages. Basically, I hated only one thing in the IT-environment: database engines! At that time, I was introduced to Ingres on Sun 1 workstations. However, I don’t think this was the cause of the problem ;-) Anyway, at that time I promised to myself to stay away from database engines for the rest of my life. But, as I wrote before, never say never! After a short foray into Informix, I had my first contact with Oracle7 in 1995. Since then, I have been focussing on understanding how the Oracle database engine works and, therefore, how to correctly use it to leverage its power.
