Back to the University
The last crusade :P

After the exams period, I'm back to the University. I hope that's my last semester, at least as an ETIS student. Now I'm learning Network Programming and Data Structures.

$here and $there

That returns true. I finish working at 2 pm and Tuesday, Wednesday and Thursday I start classes at 3'10 or 3'15 pm, so some days I arrive late at class...

DFP (or Degree Final Project)

Finally I earned enough credits to ask for a Degree Final Project. I have chosen Automatic java swing form generator using APT and reflexion technics, but until this Friday I won't know if I can do it. Other choices (we can request up to 5 DFP's) were Online Shop implementation with J2EE, Project Time Manager Distributed Application, Game for Symbian systems and Bidimensional and multiplatform game development

Didn't pass it
Yesterday was published the qualifications list for "Ampliació de Bases de Dades" (databases subject at UB). I knew it wasn't my best exam, but at least I expected to pass it.

Never expect.

Next Monday I'm going to an interview with the teacher, at least to know where I failed. Moreover, it's curious I passed the Communications & Networks exam, which supposedly was harder than the other.

Work
This week they made a mistake paying a supplier's invoice to me!... but I'm honest and I returned them all the money. I was rich for some days, now I'm poor back :P

However, today hasn't been a nice day at work.

J2ME
I bought a little guidebook to learn the basics of J2ME (Java for mobile devices) programming; right now just for fun, but it's a very interesting area and I think I could use it professionally in a future.

From this newspaper printed edition:

Darkness is faster than light. When light arrives somewhere darkness was already there.

salmoni, I have a similar issue with Firefox. If I misspell a web address e.g. http://http://www.google.com Firefox takes me to El País (spanish newspaper). Other people got redirected to Microsoft's website (!). I wonder why it's happening this. I thought that could be somewhat related with cache pages, but I had never visited El País before!

(This line has been added some hours later) sneakums, thanks for your reply :)

Getting usergroup in PostgreSQL
I'm building with a classmate a console application (written in Java) which connects to a PostgreSQL database.

Eventually we wanted to know in which user group was the user trying to connect to the database. Looking for some information about this, we found there's a table called pg_group where for each group we have a field with users' id (grolist). Then the problem was to know where a concrete id was present. We thought grolist was a plain string, so we had to code a StringTokenizer to get the id's, and then test if it was the one wanted. That resulted in an ugly, unefficient code which I wanted to rewrite.

Fortunately, we misunderstood the type of data stored in the field grolist. It's an array of id's instead a string. So, and after visiting this page :P, I finally could solve our problem like follows:

private static void setGroup() throws SQLException {

ResultSet rs2;
String myGroup,query;

query = "SELECT groname FROM pg_group WHERE "+idUser+" = ANY(grolist);";

rs2 = DBConnection.execQuery(query);
rs2.next();

myGroup = rs2.getString(1);
