Change date of git tag (or GitHub Release based on it)
... git checkout SHA1_OF_PAST_COMMIT
git tag -m"Retroactively tagging version 1.5" v1.5
And while that's perfectly usable, it has the effect of putting your tags out of chronological order which can screw with build systems that look for the "latest" tag. But have no fear. Linus thought of everyt...
Why does changing 0.1f to 0 slow down performance by 10x?

How do I use reflection to call a generic method?
...nerating code for you), the open source framework Dynamitey (.net standard 1.5) gives you easy cached run-time access to the same calls the compiler would generate for you.

How dangerous is it to compare floating point values?
...teger (1), versus what happens if you first round it to one decimal place (1.5) then round that result to an integer (2). This is actually one of the nastiest areas to deal with in floating point, since the behaviour of the compiler (especially for buggy, non-conforming compilers like GCC) is unpred...
Fastest hash for non-cryptographic uses?

What new capabilities do user-defined literals add to C++?
...lass citizens of the language, as are build-in types. So, if you can write 1.5f and 1000UL, why couldn't you write 25i or even 100101b? To the contrary of C and Java, user types are not to be considered second-class citizen of the language in C++.

Why is reading lines from stdin much slower in C++ than Python?
... fraction of its larger total time.
In fact I did some quick tests with a 1.5 gigabyte file of garbage, on a Linux 3.13 (Ubuntu 14.04) system, obtaining these results (these are actually 'best of 3' results; after priming the cache, of course):
$ time wc -l < /tmp/junk

Speed comparison with Project Euler: C vs Python vs Erlang vs Haskell
...ng this declaration with -export([solve/0]). gives a much better speedup: 31.5 seconds (almost 35% from the baseline).
But the code itself has a problem: for each iteration in the factorCount loop, you perform this test:
