That's what friends are — people who share your crazy outlook and protect you from the world… Friendship is an island you retreat to, and you're all on the floor and laugh at all the other ninnies who don't have enough brains to have your good taste.
— Ray Bradbury
The leader election and failure detection mechanisms are fairly mature, and typically just work… until they don't. How can this be? Well, after a lengthy investigation, we managed to uncover four different bugs coming together to conspire against us, resulting in random cluster-wide lockups. Two of those bugs lay in ZooKeeper, and the other two were lurking in the Linux kernel. This is our story.
I love reading bug investigation write-ups like this.
The tobacco industry might once have funded a study that says that smoking is less dangerous than coal mining, but here we have a study about coal miners smoking. Probably while they are in the coal mine. What I mean to say is that there is no scenario in which "user choices" vs. "the algorithm" can be traded off, because they happen together.

At a moment when American lawmakers are reconsidering the broad surveillance powers assumed by the government after Sept. 11, the lower house of the French Parliament took a long stride in the opposite direction Tuesday, overwhelmingly approving a bill that could give the authorities their most intrusive domestic spying abilities ever, with almost no judicial oversight.
The money quote from the discussion of how the (lack of) oversight works:
While in theory, the prime minister would act independently, it would probably be difficult for him or her to oppose the intelligence services, because they would most likely be supplying information about possible terrorist or criminal targets.
It is easy in the world to live after the world's opinion; it is easy in solitude to live after our own; but the great man is he who in the midst of the crowd keeps with perfect sweetness the independence of solitude.

Naturally, I want them to learn about abuse of authority on a breathtaking scale. But I want them to confront something more painful and more dangerous: I want them to see humanity and what we are capable of.
What makes memory magical is its imperfections and its unpredictability; try as we might, we never quite control it. It draws our attention to the margins of stories that once seemed to be the main events.
— Walter Kirn, Remembrance of Things Lost
At the University of Nottingham in Britain, researchers have rediscovered an ancient medicinal elixir that appears to fight a very modern scourge: a deadly drug-resistant bacterial infection rampant in hospitals.
