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...
Secure hash and salt for PHP passwords
...rcing a password policy of X length with X many letters, numbers, symbols, etc, can actually reduce entropy by making the password scheme more predictable. I do agree. Randomess, as truly random as possible, is always the safest but least memorable solution.
So far as I've been able to tell, making...
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.

Why is Swift compile time so slow?
... with high accuracy whether your refactorings (explicit casts, type hints, etc...) are lowering compile times for specific files or not.
NOTE: technically you could also do it with xcodebuild but the output is incredibly verbose and hard to consume.

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.

To turn on the GUI you have to put this in your vagrant config Vagrantfile:

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

What is the fastest way to send 100,000 HTTP requests in Python?

What's the difference between the atomic and nonatomic attributes?

Minimal web server using netcat
I'm trying to set up a minimal web server using netcat (nc). When the browser calls up localhost:1500, for instance, it should show the result of a function ( date in the example below, but eventually it'll be a python or c program that yields some data).
My little netcat web server needs to be a w...
