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

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:
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')
