Spell checking in vim is very easy and just needs the following command:

:set spell spelllang=en_us

This will highlight all misspelled words. To turn off the spell checker just type in command-mode:

:set nospell

For german language we need a few files:

mkdir -p $HOME/.vim/spell
wget -P ~/.vim/spell/ http://ftp.vim.org/vim/runtime/spell/de.utf-8.spl
wget -P ~/.vim/spell/ http://ftp.vim.org/vim/runtime/spell/de.utf-8.sug

Now we can use the following vim-command to enable the german spell checker:

:set spell spelllang=de

Many years ago, someone mentioned on a congress that apache has an interesting feature: if apache doesn’t know a file-extension, it will just take the next one. If someone saves a file called “shell.php.ab”, apache would not know what to do with the extension “.ab”. So it will just skip this one and uses the next one and the file “evil.php.ab” becomes “evil.php” and gets executed. I wondered how long it will take until a related bug will occur and I was not surprised when I read aboutthis nasty bug.

Overview

• System affected: VirtualBox
• Software-Version: prior to 5.0.32, prior to 5.1.14
• User-Interaction: Required
• Impact: A Man-In-The-Middle could infiltrate an Extension-Pack-Update to gain a root-shell

Certificate Transparency is a great idea. All certificate-related activities on a certificate authority will be logged into a public database(it’s a merkle-table), so that anyone can monitor or review the certificates. Commodo published a very handy web-tool to query the logs.

Irssi 1.0.0 has been released in January 2017. This is a major release with lots of new features and security fixes.

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:

sed -i '1 s/^\xef\xbb\xbf//' virtualbox.tex
