How can you ensure all the philosophers can eat reliably without starving to death? In order to eat, a given philosopher needs to use both chopsticks. There is one chopstick between each philosopher, to their immediate right and left. The philosophers alternate their time between eating and thinking. In front of each philosopher is a large plate of rice. Rerun the transaction.ĭeadlocks are a classic computer science problem, often taught to computer science students as the Dining Philosophers puzzle.įive philosophers sit around a circular table. Transaction (Process ID 54) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. One major surprise in the development of Stack Overflow was this recurring and unpredictable gem: That's not to say everything has been copacetic. I hadn't contacted him in any way I myself only found out about his reaction third hand. Still, I was humbled by the way Robert picked this up so enthusiastically through the community. For what it's worth, Robert Scoble was enthused about Stack Overflow, though it did not make him cry. Joel Spolsky also seems to think it's going well, but he's one of the founders so he's clearly biased. That's because I've been busy building that Stack Overflow thing we talked about. Table handler doesn't support NULL in given index.You may have noticed that my posting frequency has declined over the last three weeks.
