Is this for real?

Read what Bjarne Stroustrup said about creating C++ here. Then tell me what you think.
I must admit I always found C++ a bit weird. :)

More space on Linux HOME partition

I've been trying to post this for a while, but never came to it.
Here it goes.

On every Linux partition there is a certain percent (usually 5%).
For certain partition you can check the amount of reserved space like this:
sudo dumpe2fs /dev/sda3 | grep "Reserved block count"

On my computer I had about 6Gb of reserved space.
You can gain those 6Gb of space back simply by using:
sudo tune2fs -m 0 /dev/sda3

I DON'T recomend using this on you root, boot, ... partitions. More on this can be read at How to Gain Couple Of Gb Of Free Space On Linux

First


Two days ago I bought an HTC Desire phone with Android 2.2. I'm still learning, installing applications, ... This is my first smart phone and it's great. :))

This is also my first post from the phone.

Compile DB2 plugin for Qt on Linux

Steps:
- get Qt from Nokia's page
- install it
- run configure like this:
./configure -plugin-sql-db2 -v -I /opt/ibm/db2/V9.7/include -L /opt/ibm/db2/V9.7/lib64/
make
make install (if you want to install it)


- this should compile DB2 plugin for Qt. Now you can use this installation or copy generated Qt db2 plugin (libsqldb2.so) to /usr/lib/qt4/plugins/sqldrivers

Access DB2 via ODBC on Linux

This is how to install ODBC on Linux (Kubuntu 10.04) and access it.
Steps:
- install DB2 (I always install everything)
- install unixODBC
- edit $HOME/.odbc.ini :
[DB_NAME]
Description = Connection to DB_NAME
Driver=$HOME/sqllib/lib/libdb2.so

- run db2ca and add DB_NAME (don't forget to add ODBC)
- now you can use it on Qt for example like this:
QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");
db.setDatabaseName("DB_NAME");
db.setUserName("DB_USER");
db.setPassword("DB_PASS");
db.open();
QSqlError error = db.lastError();
qDebug() << "db error = " << error;

QSqlQuery query = db.exec("SELECT 1 FROM SYSIBM.SYSDUMMY1");
while (query.next() == true) {
qDebug() << query.value(0).toString();
}

DB2 9.7.1, db2start and SQL1042C

As you may know I'm running Kubuntu 9.10.
The other day I installed DB2 Express-C 9.7.1 on it. When I tried db2start I got:
SQL1042C An unexpected system error occurred. SQLSTATE=58004

If you get the same try running db2ftok and then db2start again. It works for me.
