Deny Internet in Ubuntu

posted in: Linux Archives | 0

I have phases in my work cycle, where I want to limit internet access to myself. Thus, I created a »work-user« and in the user’s properties I unticked the boxes 

  • Connect to internet using a modem
  • Connect to wireless and ethernet networks
  • Use modems

I thought that should do the trick, yet it didn’t restrict internet access to this user. I tried various other things to deny access to network and web and finally found something useful at ubuntuusers.org (German):...   READ MORE

ffmpeg-GUI

posted in: Linux Archives | 0

I was somewhat flabberghasted when I found out my mobile phone (Sony Ericsson Cyber-shot) was unable to play .mp4, .flv, .avi and what else I tried. It refuses to play all video formats save .3gp.

I was unable to convert to this with avidemux. Google quickly told me that ffmpeg could do the trick. But being unfamiliar with bitrates and stuff I was happy indeed when I found Mobile Media Converter, which is a neat and lean GUI for ffmpeg (Mac, Linux and Win). It even sports convenient batch process via drag & drop. Have fun.

World Wide Food Chain

posted in: www Archives | 0

This last weekend I understood a lot about the internet food chain: There are the smart guys and there are the monkeys. The smart guys find out how to crack a system. They publish their stuff and move on. The smart guys are too busy to play around.

As soon as the smart guys make the security hole public, the swarm of pimple stricken milksops with teenage angst who read what the smart guys publish come marauding. They upload a bit of this, toy around a bit in that and then claim they »hacked« something while they really only hacked their pants once more....   READ MORE

Groucho Marx Job Application

After graduation naturally comes application. Now it seems that application naturally comes with frustration.

Each and every company knows exactly what they want to a degree that just saw me printing 14 pages of a single job description – the job being »PR nut«....   READ MORE

»Might Make You Laugh«

posted in: Random | 0

Yesterday we arrived in London for a short holiday. In the early evening we were rambling the streets, not sure what to do. When at last we made our minds up and opted for cinema, a couple stopped us. Something was with their daughter, I did not quite get what, but it was the reason they couldn’t make it to the theatre. If we fancied to see »Absurd Person Singular« at the Garrick in fifteen minutes? He said it was a comedy and that it might make us laugh.

Given my theater experiences lately I honestly wasn’t too keen; but A. already had taken the tickets – and off they went in a great hurry....   READ MORE

ΛαΤεΧ in Greek

posted in: LaTeX Archives | 0

There are various possibilities to include Greek text in your LaTeX document. The three ones I found are these:

  1. $\Gamma\rho\varepsilon\varepsilon\kappa$ gets you Γρεεκ allright, but it looks clumsy and lacks all the accents etc.
  2. betababel. It does not work with my customised control sequences, and I am too lazy to change them and learn them all anew.
  3. polutonikogreek. Neat, slim, worked straight away.

Nos. 2 & 3 use ngerman, so make sure they don’t start a fight with german....   READ MORE

Timestamp your LaTeX Documents

posted in: LaTeX Archives | 2

While working on a somewhat larger scale document I always end up with numerous prints, .dvis, .pdfs and so on and so forth. Once, I lost all my original .tex documents and thus had to copy everything from a pdf and reformat it. In a case like that, it sure is handy to know exactly with which version you are dealing and which one is the latest. So for my thesis I wanted to add a little automatic timestamp to each print. Sure enough I found timestamp.sty. Just go to your local package repository, create a folder called <timestamp> and save timestamp.sty into it. With

\usepackage{timestamp}

in the preambel and...   READ MORE

A Mighty Hunter

posted in: Random | 0

In the course of writing my thesis I came across Nimrod, grandson of Ham, great grandson of Noah (Gen 10, 1-12). Now Nimrod is not only »a mighty hunter before the Lord: wherefore it is said, Even as Nimrod the mighty hunter before the Lord.« (Gen 10, 9), according to Wikipedia, he – under the name of Namrūd ibn Kan’ān – also tried to build a tower so he could reach Allāh and dispossess him. Allāh did not at all approve of this plan, so he came up with a rather creative punishment:

Allāh ließ eine Mücke durch die Nase in sein Hirn fliegen. So wurde Namrūd 400 Jahre gequält, bis er starb....   READ MORE
