Change date of git tag (or GitHub Release based on it)
...d:
Go back in time to the commit representing the tag
Delete the tag (locally and remotely)
This will turn your "Release" on GitHub into a Draft that you can later delete.
Re-add the same-named tag using a magic invocation that sets its date to the date of the commit.
Push the new tags with fix...
Is calculating an MD5 hash less CPU intensive than SHA family functions?
...s with sphlib, a library of hash function implementations in C (and Java). All implementations are from the same author (me) and were made with comparable efforts at optimizations; thus the speed differences can be considered as really intrinsic to the functions.
As a point of comparison, consider ...

Replace first occurrence of pattern in a string [duplicate]
... much better than the regex imho, this is what the regex will eventually do anyway, after skipping overhead. In very long strings with the result very far at the end, the regex impl might be better as it supports streaming the char array, but for small strings, this seems a lot more efficient...
Is a `=default` move constructor equivalent to a member-wise move constructor?
... decl-specifier-seqopt declarator virt-specifier-seqopt = default ;

Strictly speaking - you have no choice but calling either hostname(1) or - on Unix gethostname(2). This is the name of your computer. Any attempt to determine the hostname by an IP address like this
InetAddress.getLocalHost().getHostName()

Should I pass an std::function by const-reference?
...rmance, pass by value if you are storing it.
Suppose you have a function called "run this in the UI thread".
std::future<void> run_in_ui_thread( std::function<void()> )
which runs some code in the "ui" thread, then signals the future when done. (Useful in UI frameworks where the UI ...
How to declare a structure in a header that is to be used by multiple files in c?
...ting it in an header file, and include this header file whenever needed.
shall we open a new header file and declare the structure there and include that header in the func.c?
This is the solution I like more, because it makes the code highly modular. I would code your struct as:
#ifndef SOME_HEADER...
Is recursion ever faster than looping?
...airly expensive compared to iteration (in general) because it requires the allocation of a new stack frame. In some C compilers, one can use a compiler flag to eliminate this overhead, which transforms certain types of recursion (actually, certain types of tail calls) into jumps instead of function...
