What's the difference between hard and soft floating point numbers?
...ree ways to do floating point arithmetic:
Use float instructions if your CPU has a FPU. (fast)
Have your compiler translate floating point arithmetic to integer arithmetic. (slow)
Use float instructions and a CPU with no FPU. Your CPU will generate a exception (Reserved Instruction, Unimplemented ...
Run an untrusted C program in a sandbox in Linux that prevents it from opening files, forking, etc.?
...rotect against memory overuse and any fork bombs, as well as put a stop to CPU hogs. nice(1) can lower the priority of those programs so that the computer can be used for any tasks that are deemed more important with no problem.

Static linking vs dynamic linking
... is usually negligible. Inside the DLL there is some more overhead on i386 CPU's, because they can't generate position independent code. On amd64, jumps can be relative to the program counter, so this is a huge improvement.
2) This is correct. With optimizations guided by profiling you can usually ...

How do I debug Node.js applications?
...
I don't find the cpu reports from nodetime very helpful: 1. I just get a tree of methods, with no 'self' time. 2. Seems like the tree branches are trimmed below a certain number of precentage. Those 2 makes it very difficult to undestan...
Why wasn't PyPy included in standard Python?
...tten in C, which is traditionally the way Python applications have handled CPU-intensive tasks (see for instance the SciPy project).
The PyPy JIT compilation step itself costs CPU time -- it's only through repeated running of compiled code that it becomes faster overall. This means startup times ca...
