Is there a way to iterate over a range of integers?
...
Debating the runtime performance of nanosecond CPU operations, while common in Goland, seems silly to me. I'd consider that a very distant last consideration, after readability. Even if CPU performance were relevant, the contents of the for loop will almost always swamp w...
Warning on “diff.renamelimit variable” when doing git push
...
Although it also could be viewed as a hard-coded bound on the amount of CPU
time we're willing to allow users to tell git to spend on handling
renames.
An upper bound may make sense, but unfortunately this upper
bound was neither communicated to the users, nor documented anywhere.

.NET JIT potential error?
... new x86 configuration (I'm on running X64 Windows 2008 and was using 'Any CPU')
Debug Build
Got the correct output both F5 and CTRL+F5
Release Build
Correct output with Debugger attached
No debugger - Got the incorrect output
So it is the x86 JIT incorrectly generating the code. Have delet...
how to File.listFiles in alphabetical order?
...
@CPU100 i believe that by using the list() instead of listFiles() gives the advantage of having only the file names without the parent directory paths, resulting in shorter strings and lesser cpu time to sort/compare.

API pagination best practices

memory is cheaper than network/CPU speed. So if creating a page is very expensive (in terms of network or is CPU intensive), then caching results is a valid approach @DeepakGarg

Why would you use an ivar?
...ot spots, but none of these inefficiencies are hot spots on their own. The CPU time is just averagely spread among them, yet each of them only has such a tiny fraction of it, it seems a total waste of time to optimize it. And it's true, optimizing just one of them would help absolutely nothing, opti...

What if the next CPU has twice as many registers?
The converse of this question would be: What functionality do compilers provide?
I doubt you can/want to/should optimize your ASM better than gcc -O3 can.
