Pros and cons of patenting and IP

Maloi posted a link about the pros and cons of Intellectual Property (IP): on IP.
I think it’s a rather good article which is clearly against patents but gives reasonable arguments for its point of view.
Money Quote:

So, patents are bad for the vast majority of small innovative firms, and they are good for trolls that produce no wealth, publicly funded research institutions that should not be driven by a profit motive, legal cartels that engage in global price fixing, and wealthy firms that speculate on future market movements.

Enjoy reading and get rid of that fucking IP.

Traffic Wohnheim Gutz/Reiba 2003-present

I was curious and put together some code to generate a chart of the traffic usage from late 2003 until now.
The red bars are incoming traffic, green is outgoing. The bars only represent the traffic beeing accounted for, meaning inbound/outbound of the TU Dresden network.
The traffic limit was raised from about 3 GByte per week to 7 GByte over 7 consecutive days. The traffic per user is round about 10G/month today (it started out with round about 2G/month).
The huge dent in 2011 was in August, our servers broke and we didn’t count traffic for approx 2 weeks. In september most of the students are home, that’s why the traffic goes down as well.

I’m looking forward to do more of these charts and I’m looking forward presenting them to you.

Writing CD’s from the commandline

Because I was in need of it and because I don’t wanna forget it:
wodim -v speed=2 dev=/dev/sr0 -data my.iso && eject /dev/sr0.

Something else (very) usefull: check the integrity (here of a grml file):
gpg --decrypt grml64-full_2012.05.iso.sha1.asc | sha1sum -c -
