I found a cool programm, that can count lines of code for several programming languages.

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 did a clean install of Ubuntu 11.04 and copied all the needed configs from my old 10.10 installation. But i could not find the needed folders for the network and wireless settings, so i searched for them and this is what i found.

Today is backed up my SSD so i can install Ubuntu 11.04 fearlessly.
Problem was that dd was very slow, but i found a solution.

I tried to install Ubuntu 11.04 on a 4 GB USB-Stick today, but was failed by the installer who wants at least 4.4 GB free space. This is unnecessary much, because a normal Ubuntu install will stay below 2.5 GB.
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.
I use the digg-digg Wordpress Plugin on this blog and found a annoying error - the like button does not use the correct url. I found out why and how to correct it.

If you want to send somebody parts of your svn repository, then you mostly do not want to give them your .svn folders with all the settings and base files inside.
I wrote a short command to remove all the .svn folders recursive from the current directory:
find . -name ".svn" -type d
- Will list recursive all directorys named '.svn' in current directory.
for dir in $(...); do rm -rf "$dir"; done
- Will delete all items from the result of $().
If you do not want to type and remember that much, you can easily add this as a bash alias.
Open your .bashrc and add this line:
The next time you start a bash, you have a new command "unsvn".
