30 Years of E-Mail in Germany

Today, it has been exactly 30 years since Germany’s first e-mail was received in Karlsruhe. This anniversary was celebrated with a small event at the Karlsruhe Institute of Technology (KIT). A press conference was organized and students launched 72 helium balloons shaped as 0s and 1s that were arranged to read 0x4B40726C7372756865. (I didn’t actually verify this.) While personally I disapprove of such intentional and needless environmental pollution, it was a great opportunity for us to raise awareness for privacy of e-mail communication and teach people about OpenPGP.

SCC Supports OpenVPN

After having had lots and lots of troubles with the proprietary Juniper VPN client (On some GNU/Linux versions including the distro used by the computational chemistry group it refused working at all!) formerly exclusively recommended by our university’s IT management, the Steinbuch Centre for Computing (SCC), I was very happy to see that now (since when?) they also support OpenVPN.

On my Ubuntu 10.04 + GNOME 2 system, running

sudo apt-get install network-manager-openvpn-gnome
sudo -r shutdown now

(yes, it needs to reboot…) was sufficient to allow me importing the configuration file provided by the SCC into the GNOME NetworkManager. (VPN Connections → Configure VPN… → Import Then enter your user name and password and confirm.) The configuration file along with some additional information is available from the SCC’s website.

It should be installed by default but if not, first install OpenVPN via

sudo apt-get install openvpn

I hope many students and employees will now use OpenVPN so they switch from trial to regular operation. Kicking out the Juniper client was an important step for me towards a fully free desktop.

TOC Organic Chemistry II

I was just consulting my OC II script when I found that a good table of contents could make things much easier. You can download such a list from the professor’s site. However, I thought I’ll format it somewhat to make it handier. I didn’t expect this to become such a huge task including a really dirty LaTeX hack to override the maximum list depth. Now I’ve wasted far too much lifetime for nothing, I hope that at least someone else might have use for this list as well.
