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

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.

So I checked the encoding of the file and saw that it looked like this:

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:

Mysql does not connect to a given port if the host is localhost.

Ansible is a powerful configuration management tool. For developing and distributing ansible-roles we use Gitlab at Toscom. In this article I'll describe how to automatically test ansible-roles for different Linux-Distributions in Docker-Container using Gitlab-Runner whenever someone pushes changes into our Gitlab-Repository.

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.

To give up who we are

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:

I installed Raspbian(Debian Jessie) with Kodi on my Raspberry Pi and I use my Pi as a Meda Center. This Media Center plays music, mostly radio stations, all day long. I can easily control this media-center using the Yatse-App on my phone. The Setup is almost perfect, but just almost. Sometimes I prefer to listen to my Spotify-Playlists. At the moment there are no really good music addons for that. So I came to the idea to pair my phone via bluetooth with my Pi and use the audio output of my phone to play the Spotify-playlists.
