Method names for getting data [closed]
...re lengthy access that involves transfer of data from place to place (a-la CPU fetching) or database fetching. For instance, Hibernate's query language has a Fetch construct. Developers often use methods based on their expectations of the name rather than by reading documentation so avoiding sending...

Array.Copy vs Buffer.BlockCopy
...ood performance is almost surely due to locality of reference exploited by CPU L1/L2/L3 memory caching in conjunction with no method call overhead.
For double buffers on 32-bit machines only: The explicit loop copy routine is better than both alternatives for all buffer sizes tested up to 100k. Th...
What is the difference between _tmain() and main() in C++?
...ed as the pair of bytes \0 followed by the ASCII value.
And since the x86 CPU is little-endian, the order of these bytes are swapped, so that the ASCII value comes first, then followed by a null byte.
And in a char string, how is the string usually terminated? Yep, by a null byte. So your program ...

...t may be in for example Security -> Virtualization or in Advanced -> CPU Setup. If you can't find any of these options, search Google for enable virtualization (the kind of computer you have). Don't change anything in the BIOS just like that at random because otherwise it could cause problems ...
Why start an ArrayList with an initial capacity?
... tell ArrayList to allocate a larger storage to begin with as to not waste CPU cycles when it tries to allocate more space for the next item. Thus to allocate some space at the beginning is more effiecient.

Are there any downsides to passing structs by value in C, rather than passing a pointer?
...
Unless your struct is tiny or your CPU has many registers (and Intel CPUs have not), the data ends up on the stack and that is also memory and as fast/slow as any other memory. A pointer on the other hand is always small and just a pointer and the pointer itse...
What's an object file in C?
...Object file contains low level instructions which can be understood by the CPU. That is why it is also called machine code.
This low level machine code is the binary representation of the instructions which you can also write directly using assembly language and then process the assembly language co...
How to get the return value from a thread in python?

return wrap
Then, whenever you need to push cpu intensive or blocking code off the event loop thread, you can put it in a decorated function:
