The first day of the 33c3 was fantastic. There were great talks(among others) about "Certificate Transparency", "Nintendo Hacking", "IPv6-Scanning" and "PHP7 Issues". I saw wicked, funny and amazing installations. People celebrate their obsession for tech with a lots of respect for each other. This congress is like being in another dimension (or time?) and absolutely works for me.

I wish you all a Very Merry Christmas and a beautiful time

PS: I found this nice html-css-hack at codepen.io

I experienced an interesting problem: on a Debian Jessie host with squidguard: update-squidguard threw the following error-message:

root@34697f9f06a2:/# update-squidguard 
/usr/sbin/update-squidguard: 69: test: dbhome: unexpected operator
Rebuild SquidGuard database - this can take a while.

On Debian Wheezy it returns with the following error:

I got the following error while compiling a Latex-File:

compiling MyLatexfile.tex...
tex/virtualbox.tex:1: Package inputenc Error: Unicode char \u8: not set up for use with LaTeX.

file tex/virtualbox.tex 
tex/virtualbox.tex: LaTeX document, UTF-8 Unicode (with BOM) text, with very long lines

It seems that inputenc does not like utf-8 with Byte Order Mark. So I removed it using the following sed-command:

This is a one-liner to search for installed packages containing a searchstring and then deinstall them using "apt-get remove":

apt-get remove --purge $(dpkg --get-selections | cut -f 1 | grep DPKG-SEARCHSTRING | xargs echo " " | tr -d '\n')

Today this blog has reached it's second anniversary.

The best editor of this world celebrates it's 25th anniversary

Vim version 1.14 was the first public release of Vim, distributed on Fred Fish disk 591. The executable has the version information "Vi IMitation v1.14 (Nov 2 1991 0:36:35)". That is exactly 25 years ago. Raise your glass to Vim! (Bram Moolenaar)

So HAPPY BIRTHDAY VIM

Sometimes we have to migrate some tables from one host to another. And sometimes we want to migrate users as well. This is how I managed to do this..

First let's read out all users

mysql --batch --skip-column-names -e "SELECT user, host FROM user" mysql

Output:
