What is the difference between a process and a thread?
... referring to. Threads are an operating environment feature, rather than a CPU feature (though the CPU typically has operations that make threads efficient).
Erlang uses the term "process" because it does not expose a shared-memory multiprogramming model. Calling them "threads" would imply that the...
kernel stack and user space stack
...sable, and therefore will require one set under its own control. Different CPU architectures implement this in different ways; x86 CPUs automatically switch stackpointers when privilege mode switches occur, and the values to be used for different privilege levels are configurable - by privileged cod...
Compiled vs. Interpreted Languages
...e. Or let's say: There are native compilers (creating machine code for the CPU to eat), and not-so-native-compilers (creating tokenized stuff, i.e. intermediate code, that some just-in-time compiler compiles to machine code before (or during) runtime ONCE), and there are "real" non-compilers that ne...
Why doesn't C have unsigned floats?
...d floats is because there is no equivalent machine code operations for the CPU to execute. So it would be very inefficient to support it.
If C++ did support it, then you would be sometimes using an unsigned float and not realizing that your performance has just been killed. If C++ supported it ...

Update:
There are also two ways to disable the CPU affinity-resetting behaviour of OpenBLAS itself. At run-time you can use the environment variable OPENBLAS_MAIN_FREE (or GOTOBLAS_MAIN_FREE), for example
OPENBLAS_MAIN_FREE=1 python myscript.py
Or alternatively, if you...

What is data oriented design?
...our data for efficient processing. Especially with respect to cache misses etc. Data Driven Design on the other hand is about letting data control a lot of your programs behavior (described very well by Andrew Keith's answer).
