What is an uninterruptible process?
Sometimes whenever I write a program in Linux and it crashes due to a bug of some sort, it will become an uninterruptible process and continue running forever until I restart my computer (even if I log out). My questions are:

How to decide between MonoTouch and Objective-C? [closed]
After sitting through a session today on Mono at a local .Net event, the use of MonoTouch was 'touched' upon as an alternative for iPhone development.

Why does i = i + i give me 0?

In 32-bit twos-complement arithmetic:
i does indeed start out having power-of-two values, but then overflow behaviors start once you get to 230:
230 + 230 = -231
-231 + -231 = 0
...in int arithmetic, since it's essentially arithme...
Why would adding a method add an ambiguous call, if it wouldn't be involved in the ambiguity
...have found a bug in overload resolution. The bug reproduces in C# 4 and 5; it does not reproduce in the "Roslyn" version of the semantic analyzer. I've informed the C# 5 test team, and hopefully we can get this investigated and resolved before the final release. (As always, no promises.)
