Zuhälter verklagt Nike, nachdem er Freier misshandelt hat:
Den Freier trat er so heftig ins Gesicht, dass sein Gesicht komplett zerschunden war. Dieser brauchte anschließend eine Schönheitsoperation, um seine Nase wiederherzustellen. Der Mann wollte verschwinden, ohne für den Sex mit der Prostituierten zu bezahlen. Bei der Tat trug der Zuhälter Schuhe der Marke Nike Air Jordan.

Wegen dieser Tat fordert Sirgiorgio C. nun 100 Millionen Dollar von Nike, wie Oregon Live jetzt berichtet.

Der Grund: Nike hatte keinen Warnsticker auf den Schuhen platziert, die davor warnen, dass die Jordans als Waffe missbraucht werden könnten.

Fix backlight function keys in Ubuntu 13.10 on Clevo W840SU [Jan. 6th, 2014|07:36 pm]
[Tags|, , , , ]

More of a note to myself...:
  • Notebook: Schenker S403 (actually Clevo W840SU)
  • Operating System: Ubuntu 13.10 (same in Ubuntu 12.10)
  • Problem: Fn+F9 to increase display brightness (backlight) not working

Fixed by adding paramter "acpi_backlight=vendor" to kernel command line.

In fact, this was a bitch to track down.

Solving the Key Exchange Problem [Dec. 10th, 2013|03:51 pm]
[Tags|, , ]

The main hassle about using encryption is the secure exchange of encryption keys. There are key servers and webs of trust and certificates and signatures and certificate authorities, but all that is magic to the average user and thus just as trustworthy as and generally more complicated than other closed systems (e.g. WhatsApp, Skype, etc.) which are not to be trusted.

So how to solve this problem in the modern world?

For many use cases the solution could be as simple as using Smart Phones and QR-Codes!

Many users who like to communicate privately also meet each other in person from time to time and could therefor share their encryption keys in person, if they only had a comfortable way of doing so.

All a user should have to do is:
  1. Generate a key
  2. Securely share that key with friends
  3. Communicate safely
All of that should be trivial to do.

My proposal: A user can generate his public key as a QR code using a smartphone app and allow others to scan that code and store the key as they meet. That QR code could also be printed on business cards.

According to Wikipedia a QR code of level "L" may contain up to 23 648 Bits of information, which is more than enough to hold regular asymmetric encryption keys which currently use about 2048 Bits.

What do we need for that?
  1. a smartphone app which generates QR codes from encryption keys
  2. a smartphone app which imports encryption keys from QR codes
  3. Communication apps that use those keys.
  4. an import/export mechanism to synchronize those keys between multiple devices of one user.

And all those MUST be easy to use.

Apps for encryption do exist, such as SecureSMS or APG. Maybe some integration effort is needed to get those to work with the locally shared keys.

Greetings from Bangkok [Nov. 2nd, 2013|04:32 pm]
[Tags|, , ]

I'm in Bangkok, again.



We had spent two weeks at the beaches of Hua Hin and Koh Samui and found ourselves once again overwhelmed by the city of Bangkok today. This city just does not feel right in so many ways. Down at the bottom of the streets it is full of cars, motorbikes, dirt and funny and not so funny smells and most of all: people. Soo many people. And everything is so narrow: the markets, the small streets, the shops. The whole city seems like a complete mess.

Yet again, everything is so huge: shopping centers of sizes that Europeans aren't able to grasp or describe – not only one, but six or seven right next to eachother, with bridges connecting them over the roads – skyscrapers spread all over the city as if someone had dropped them there at random will, huge roads with skywalk and skytrain above.

And in this city so old and modern at once there are the local people, the rich and the poor, and visitors/tourists tied up in messed up roles and they play those as if there was nothing to it.



So today we went to the Baiyoke Sky Hotel to get a view at the top of the scene, down from the highest Hotel of Southeast Asia. We took the elevator to the 83th floor and walked the final stairs to the rooftop (at about 300 m). And all the sudden, everything was so peaceful. The jammed Pratunam Market that we had barely pushed ourselves through to get to the tower, the crowded streets which we were almost unable to cross – it all looked so harmless, almost empty, it was amazing.
