favila / flatten.php

Created March 19, 2013 08:19

Braindump of a whole bunch of ways to flatten an array in PHP (with timing harness)

	<?php
	function flatten_for($arr) {
	$c = count($arr);
	$newarr = array();
	for ($i = 0; $i < $c; $i++) {
	$newarr[] = $arr[$i][0];
	}
	return $newarr;
	}

favila / MultiIndex.php

Created April 4, 2013 01:36

`MultiIndex` class: simple class for keeping multiple indexes on an array of items with easy derived sorting. Originally written to answer [this stackoverflow question](http://stackoverflow.com/q/15800052/1002469).

	class MultiIndex {

	protected $array;
	protected $indexes = array();
	protected $indexdefs = array();

	function __construct($array, $indexdefs)
	{
	$this->array = $array;
	$this->indexdefs = $indexdefs;

Last active July 24, 2022 17:41 — forked from anonymous/ci_lower_bound.sql

MySQL stored functions for calculating confidence intervals using Wilson scores: more precisely "Lower bound of Wilson score confidence interval for a Bernoulli parameter". Includes a P(qn) function (inverse normal distribution). See http://www.evanmiller.org/how-not-to-sort-by-average-rating.html This describes a way to rank items based on a ve…

favila / b64longs.clj

Created August 7, 2013 02:12

Encode and Decode java.lang.Long as a web-safe, identically-sortable Base64 string. I.e., the Long and the string will both sort exactly the same way, and none of the characters of the string ever need to be escaped in a web context (e.g. in html, in xml, in any part of a url). Requires net.iharder.Base64 class which is Public Domain. See http:/…

favila / parallel-chan-map.clj

Created September 19, 2013 14:32

parallel-chan-map: Read in-chan and put result of `(apply f in-chan-value args)` on out-chan, running items in "parallel" and yielding results out-of-order. Works with Clojure or Clojurescript.

	(ns parallel-chan-map
	(:require-macros [cljs.core.async.macros :refer (go alt!)])
	(:require [cljs.core.async :refer (>! close! put! chan )]))

	(defn parallel-chan-map
	"Read in-chan and put result of `(apply f in-chan-value args)` on out-chan,
	potentially running items in parallel and yielding results out-of-order.

	Function f must return something takeable (e.g. a go-block, channel, promise),
	in essence spawning a \"subprocess\" which this function manages as a pool
