Just one thing:
What about pep8 in your python code ? How can you give ‘tutorials’ on quite popular website, of such a bad quality ?

Larry Page is not being completely honest! The manner in which the PRISM program/project works does not need access from company administrators or owners, so called “direct access”; the access to the information is already there. These tech company CEOs take for granted the actual intelligence of most end users of their products. All it takes is a little digging and reading to go from ignorant to informed on these things especially on exactly how the internet works/functions in the U.S.A. I find Larry Page’s remarks just as laughable as Al Gore’s claim to “inventing” the internet/world wide web!
If you, as an end user, are reading this post; I challenge you to research these matters yourself. It really is quite simple with all the “information sites” that exist on the web today ie Wikipedia, & other online encyclopedias that actually list source material, as well as highly respected tech sites and blogs that also list their source material. Be warned: this is only the tip of the iceberg and these tech CEOs know and understand this; they are scrambling in attempt to perform DAMAGE CONTROL to save the company and what little trust thay have left from their products end users/consumers.
Am I a skeptic? I believe someone has to be or needs to be at this point in time! If your not just a little skeptical of the government, tech companies, and the people that are in charge of these agencies and companies; you need to be, even if just a little skeptic. For your own personal protection and security! I know I was a part of this community for over 14 years!

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
