I recently wanted to create a shared folder with the attribute hidden, but did not want to change the /etc/samba/smb.cnf.

So i searched where the shares created by the gnome folder-properties window where saved. The directory is:

/var/lib/samba/usershares/

This is also the place, where you might fix a broken share by deleting the config file.

Somehow the Network-Manager in Kubuntu can not connect to hidden wireless lan. But i found a simple workaround in the kubuntuforums.net:

I worked on a project where i needed to handle a lot with cURL request. At first i tried to use Zend_Http_Client, but it was too limited for my purpose. So i wrote my own cURL handler php class.

I found a "fix" that works like this:

Change timezone on your Ubuntu/Debian system by opening a Terminal and run this command:

I wrote a (very) short script to test hdd or ssd speed using dd. You can find the code here:

hdd-speed-test-1gb.sh
and as text:
hdd-speed-test-1gb.sh.txt

The script uses dd and /dev/zero for writing a 1GB sized tempfile. Then the tempfile is written by dd to /dev/null. dd produces some output where the transfer speed is mentioned. Afterwards the tempfile is removed.
It is really just a tiny script, so i do not have to remember the dd syntax every few months.
