  How MySQL optmizes ORDER BY

In some situations, MySQL will just use an index to fulfill the requirement of an ORDER BY or GROUP BY statement without extra sorting. Although ORDER BY will not have the exact match with index, index can still be used as long as the portion that is not included in the index is included in the where clause. The following queries will all use index to process the ORDER BY or GROUP BY part: SELECT * FROM t1 ORDER BY key_part1,key_part2,... ;SELECT * FROM t1 WHERE key_part1=constant ORDER BY key_p...

  Overlap Detection

How does one detect when two strings overlap? In the case below, the four-letter suffix of string 1 matches the four-letter prefix of string 2. 1: "Fire at Will" 2: "William Riker is number one" Sometimes there are several matches; finding the longest is not always straight forward. 1: "Have some CoCo and CoCo" 2: "CoCo and CoCo is here." 2: "CoCo and CoCo is here." 2: "CoCo and CoCo is here." The naïve solution is to take...

  Learn from Haskell - Functional, Reusable JavaScript

Learn You a Haskell: For Great Good? For the last couple months I have been learning Haskell. Because there are so many unfamiliar concepts, it feels like learning to program all over again. At i.TV, we write a lot of JavaScript (node.js and front end). While many functional/haskell paradigms don’t translate, there are a few techniques that JS can benefit from. There are Haskell library functions for everything. At first I thought this was just because it was mature, but then I notice...

  CSS Tools: Reset CSS

The goal of a reset stylesheet is to reduce browser inconsistencies in things like default line heights, margins and font sizes of headings, and so on. The general reasoning behind this was discussed in a May 2007 post, if you're interested. Reset styles quite often appear in CSS frameworks, and the original "meyerweb reset" found its way into Blueprint, among others. The reset styles given here are intentionally very generic. There isn't any default color or background set for the bod...
