Track-point scrolling
Why isn't track-point scrolling configured to work out to the box on Linux?
Right, everything is full of bugs. At least there's a workaround:

Generate a 8k x509 self signed ssl key for usage with a web-server like apache2 where both keys are in the same file:
openssl req -newkey rsa:$((1024*8)) -new -x509 -days 9999 -nodes -out apache.pem -keyout apache.pem
I need to get some data form a libvirt/kvm image without starting the VM. Actually the VM is broken so it wont start. Here's how I could get access to the image:
mount:
modprobe nbd max_part=63
qemu-nbd -c /dev/nbd0 /var/lib/libvirt/images/image.img
mount /dev/nbd0p1 /mnt
unmount:
umount /mnt
pkill -9 qemu-nbd
rmmod nbd

In this setup the reverse proxy server does the ssl encryption. Therefore you must trust your reverse proxy server enough to hold the private SSL certificates for your websites! Do not use this setup if you can't trust your reverse proxy sufficiently!
install apache 2
apt-get install apache2
enable mod_ssl and mod_rewrite
a2enmod ssl
a2enmod rewrite
service apache2 restart
create site configureation for the virtual host
Put this file under eg. /etc/apache2/sites-available/example.com also make sure to read trough the entire file and change it according to your setup...
You might want to change:
ProxyPass and ProxyPassReverse targets to your actual internal server urlthe SSLCertificateFile and SSLCertificateKeyFile to the actual certificates for your domain

enable site
use the name of the file you created in /etc/apache2/sites-available insted of example.com for the a2ensite command
a2ensite example.com
service apache2 reload
install redmine dependencies
apt-get install apache2-mod-passenger redmine redmine-sqlite
add desired listening port to apache config
apache ports are configured here on debian 7 /etc/apache2/ports.conf
Listen 8083
create redmine apache config
I named the site file: /etc/apache2/sites-available/redmine
<VirtualHost *:8083>
DocumentRoot /usr/share/redmine/public
<Directory /usr/share/redmine/public>
AllowOverride all
Options -MultiViews
</Directory>
</VirtualHost>
enable site and restart apache
a2ensite redmine
service apache2 restart
redmine is now running you can access it with
redmine default username: admin
redmine default password: admin
install apache2 to run as reverse proxy
install debian packages
apt-get install libapache2-mod-proxy-html
enable mod
a2enmod proxy
a2enmod proxy_http
a2enmod proxy_html
create reverse proxy config eg. under /etc/apache2/sites-available/redmine.example.com
<VirtualHost *:80>
ServerName redmine.example.com
ServerAlias redmine.example.com
ProxyRequests Off
ProxyPass / http://192.168.100.178:8083/
ProxyPassReverse / http://192.168.100.178:8083/
</VirtualHost>
enable site and restart apache
a2ensite redmine.example.com
service apache2 reload
if you want to use virtual hosts in combination with ssl you must configure SNI (server name indication)
Actually it's already enabled in debian 7 packages, all you need to do is to add this line to your /etc/apache2/ports.conf file to make it work:
NameVirtualHost *:443
make sure /etc/apache2/sites-available/default-ssl does not define <VirtualHost _default_:443> rather than *:443 and that ServerName is set.
<VirtualHost *:443>

I fixed my debain squeeze with lvm2 fulldisk encryption. When booting it always froze when doing fsck. What I did was basically booting the squeeze installation-image into recovery mode and run fsck there. If I had knows how easy this can be solved, I would have saved my self a lot of troubles.
