How to simulate Android killing my process
...if it is in the background and the OS decides it needs the resources (RAM, CPU, etc.). I need to be able to simulate this behaviour during testing so that I can ensure that my application is behaving correctly. I want to be able to do this in an automated way so that I can test if the application be...

Why is SSE scalar sqrt(x) slower than rsqrt(x) * x?
...lers like clang choose not to use reciprocal + Newton for scalar on recent CPUs, because it's usually not faster. In most loops, div isn't the only operation, so total uop throughput is often the bottleneck even when there's a divps or divss. See Floating point division vs floating point multiplic...
Node.js or Erlang
...ngle-threaded environment. So it's great at dispatching but not so good at CPU-intensive processing. To cover that ground you can fork off another process/thread that runs native C/C++ code. If all you're doing is async IO calls (ex IPC | bi-directional pipes) then node.js should be able to handle t...

Is the sizeof(some pointer) always equal to four?
... @SangeethSaravanaraj: Note that theoretically the native word size of the CPU and what the compiler decides 'int' is can be arbitrarily different, it's just it was convention for 'int' to be the native word size before x86-64 came around, where it's long to ease backwards compat.

如何解决这个问题？
有几种思路：1.重写ON_MESSAGE宏，增加ID的限制；2.模拟按钮单击消息；3.自定义WM_NOTIFY消息。基于这些思路都不能修改MFC底层的代码。

JOIN queries vs multiple queries
