What is the best collation to use for MySQL with PHP? [closed]
...the one we're going to test next:
charset utf8 collate utf8_general_ci
-- now, create the table and fill it with values
CREATE TABLE `test` (`key` VARCHAR(16), `value` VARCHAR(16) )
CHARACTER SET utf8 COLLATE utf8_general_ci;
INSERT INTO `test` VALUES ('Key ONE', 'value'), ('Key TWO', 'valúe'...
How does std::forward work? [duplicate]
I know what it does and when to use it but I still can't wrap my head around how it works. Please be as detailed as possible and explain when std::forward would be incorrect if it was allowed to use template argument deduction.

Why doesn't nodelist have forEach?
...nner text, but found that nodelist does not have a forEach method. I know that nodelist doesn't inherit from Array , but doesn't it seem like forEach would be a useful method to have? Is there a particular implementation issue I am not aware of that prevents adding forEach to nodelist ?...
How do you remove an invalid remote branch reference from Git?

You might be needing a cleanup:
git gc --prune=now
or you might be needing a prune:
git remote prune public

Comparison of full text search engine - Lucene, Sphinx, Postgresql, MySQL?
...t Lucene - because I've no idea about that.
Sphinx, on the other hand, I know quite well, so let's see if I can be of some help.
Result relevance ranking is the default. You can set up your own sorting should you wish, and give specific fields higher weightings.
Indexing speed is super-fast, beca...
Convert a character digit to the corresponding integer in C
...the same for letters, for example:
char c = 'b';
int x = c - 'a'; // x is now not necessarily 1
The standard guarantees that the char values for the digits '0' to '9' are contiguous, but makes no guarantees for other characters like letters of the alphabet.

Why does setTimeout() “break” for large millisecond delay values?
...
You can use:
function runAtDate(date, func) {
var now = (new Date()).getTime();
var then = date.getTime();
var diff = Math.max((then - now), 0);
if (diff > 0x7FFFFFFF) //setTimeout limit is MAX_INT32=(2^31-1)
setTimeout(function() {runAtDate(date, func...
Computational complexity of Fibonacci Sequence
I understand Big-O notation, but I don't know how to calculate it for many functions. In particular, I've been trying to figure out the computational complexity of the naive version of the Fibonacci sequence:

Using Gulp to Concatenate and Uglify files
...
Coming from grunt it was a little confusing at first but it makes sense now. I hope it helps the gulp noobs.
And, if you need sourcemaps, here's the updated code:
var gulp = require('gulp'),
gp_concat = require('gulp-concat'),
gp_rename = require('gulp-rename'),
gp_uglify = require(...
