Die Aktion ist sowas von durchsichtig,
das geht nicht einmal mehr als Negligé durch.

NYT: How Laura Poitras Helped Snowden Spill His Secrets
http://www.nytimes.com/2013/08/18/magazine/laura-poitras-snowden.html
Poitras endured the airport searches for years with little public complaint, lest her protests generate more suspicion and hostility from the government, but last year she reached a breaking point. While being interrogated at Newark after a flight from Britain, she was told she could not take notes. On the advice of lawyers, Poitras always recorded the names of border agents and the questions they asked and the material they copied or seized. But at Newark, an agent threatened to handcuff her if she continued writing. She was told that she was being barred from writing anything down because she might use her pen as a weapon.
“Then I asked for crayons,” Poitras recalled, “and he said no to crayons.”
She was taken into another room and interrogated by three agents — one was behind her, another asked the questions, the third was a supervisor. “It went on for maybe an hour and a half,” she said. “I was taking notes of their questions, or trying to, and they yelled at me. I said, ‘Show me the law where it says I can’t take notes.’ We were in a sense debating what they were trying to forbid me from doing. They said, ‘We are the ones asking the questions.’ It was a pretty aggressive, antagonistic encounter.”

Coffman conditions for a deadlock
There are four conditions, known as the Coffman conditions, that are necessary for a deadlock to occur. Remove any one of these, and a deadlock can’t happen:
- Mutual exclusion.
There’s a resource that only one entity can use at a time. - Hold and wait.
An entity is holding one resource while waiting for another. - No preemption.
An entity gets to decide when it releases its hold on a resource. - Circular wait.
There must be a cycle of waits, such that entity 1 is waiting on a resource held by entity 2; entity 2 is waiting on a resource held by entity 3; …; and entity N is waiting on a resource held by entity 1.

Spruch des Tages
Wenn einmal die Lebensmittelversorgung zusammenbricht,
dann kann man sich wenigstens noch freuen,
dass man bei Facebook einen schönen Garten hat.

Google Reader Alternative
Reeder verwende ich gern, aber was kommt als neues Backend als Ersatz für Google Reader in Frage?
http://feedafever.com/ Fever ist interessant und zumindest schon jetzt von der iPhone-Version von Reeder unterstützt. 30$. Hmm.
