# xkcd

xkcd is a stick-figure webcomic started by former NASA robotics contractor Randall Munroe in 2005, built around jokes about math, science, programming, and online life. The strip's cult audience among coders and scientists turned specific installments like Little Bobby Tables, Click and Drag, and Password Strength into their own standalone internet memes.

## Origin
Randall Munroe, a physics graduate who worked as a robotics contractor for NASA, registered the xkcd.com domain on January 25, 2003. In a 2006 interview with Red Hat Magazine he explained that the four-letter string came from an instant messenger handle he picked specifically because it had no pronunciation and no prior meaning[2]. For about two and a half years the site sat mostly empty.

In September 2005, Munroe started scanning stick-figure doodles out of his school notebooks and posting them to xkcd.com, and that doodle feed quickly took over the entire site to become its only focus[3]. From there the strip settled into a Monday, Wednesday, Friday publishing cadence that it still keeps.

## Overview
Each xkcd strip features stick figures acting out jokes about programming, mathematics, physics, linguistics, and online life, with a hover-over title text under the mouse that acts as a second punchline or aside[1]. Munroe draws from a small cast of visually interchangeable characters: a bald figure sometimes called Cueball, a woman with black hair often referred to as Megan, a Beret Guy, a Black Hat trickster, and a White Hat straight man[9]. The strip's dry tone and willingness to pack real equations, flowcharts, or research citations into gag panels made it a reference point for programmers and scientists[2].

Several strips grew past the regular readership into standalone memes. Comic 327, "Exploits of a Mom," introduced Little Bobby Tables, a child whose full name Robert'); DROP TABLE Students;-- is still quoted every time an SQL injection story breaks[9]. Comic 256, "Online Communities," mapped the social web as a fictional continent sized by population, and the strip spawned a sequel map after the shape of those networks changed[6]. Comic 936's "correct horse battery staple" argument for passphrases shaped how a generation of security educators taught password choice.

The strip is published under a Creative Commons Attribution-NonCommercial 2.5 license, which lets readers legally reprint, translate, remix, and teach from the comics as long as they don't sell them[5]. That permissive setup is a big part of why xkcd panels show up in slide decks, textbooks, and conference talks.

## How to Use
References to xkcd typically take the form of linking a specific comic by number for a specific joke. Common conventions include dropping comic 327 whenever SQL injection or input sanitation comes up, pointing to comic 936 in password discussions, and linking comic 256 when mapping any community space online[6]. Readers often check the volunteer-run explain xkcd wiki when a strip's math, in-joke, or title text lands outside their field, since it writes a breakdown for every published comic[4].
