As I understand it so do VLC use same encoders as ffmpeg. And yes, there are less code that can break when you use command line instead of a graphical UI.
And may I ask what mono has to do with VLC? *facepalm*

Just some thoughts about Java.
OpenJDK7 are now THE Java implementation and Oracles are just one more of the reimplementations. So you should not need to install Oracles version.
And you really don’t need to remove the OpenJDK7 installation to also have Sun Java JDK 7. Just run
sudo update-java-alternatives –list
and select which java you want to have as default java of all that is installed.
And if you want to run a program with one special version, check manpage for java-wrappers how to do that.
man java-wrappers
so you can run java program rasterizer like this:
JAVA_FLAVOR=openjdk rasterizer
JAVA_ARGS=-Xmx80m rasterizer
JAVA_BINDIR=/usr/share/
etc

Yes, it is. If you are a “5 years old schizophrenic kid” who can’t restrict what effects to use and what to not use. It’s actually usefull, if you can restrain yourself.

Agree with BA. You should teach how to remove telnetd from your servers, and tell them to use SSH instead.
And explain that telnet is not secured. It’s easy for anyone to see what you type in clear text or MIM-attacks.
Or you might want to add a kerberos version of telnetd and se to it that it denies any try without kerberos authorization.
The tool telnet is usefull, for example to explain how SMTP protocoll or HTTP-protocoll works by making the user be the client (mail client or web client).
But you do not need to install telnetd for that.

Can you resolve that name on your machine?
$ getent hosts server.example.com
192.168.0.10 server.example.com
Where this should be your IP-address and then all aliases for that machine (where you obviously change DNS name to your own. ;-)
