by students dressed as
ninjas. Inspired by "Open Source" On several occasions, fans have been motivated by Munroe's comics to carry out the subject of a particular drawing or sketch offline. – inspired by "Open Source". Munroe appeared, commenting, "Maybe wanting something does make it real", reversing the conclusion he drew in the last frame of the same strip. wearing a red cape and a pair of goggles based on his appearance in
xkcd. Doctorow later wore the costume again while accepting a Hugo Award on Munroe's behalf. •
xkcd readers began sneaking
chess boards onto roller coasters after "Chess Photo" was published. • The game of "
geohashing" has gained more than 1,000 players, who travel to random coordinates calculated by the algorithm described in "Geohashing". • In October 2007, a group of researchers at
University of Southern California's
Information Sciences Institute conducted a census of the Internet and presented their data using a
Hilbert curve, which they claimed was inspired by an
xkcd comic that used a similar technique. Inspired by the same comic, the
Carna botnet used a Hilbert curve to present data in their 2012 Internet Census. • Based on "Packages", programmers have set up programs to automatically find an item for sale on the Internet for $1.00 every day. • In response to "Password Strength",
Dropbox shows two messages reading "lol" and "Whoa there, don't take advice from a webcomic too literally ;)" when attempting to register with the password "correcthorsebatterystaple".
ArenaNet recommended that
Guild Wars 2 users create
secure passwords following the guidelines of the same comic. • The
Python Standard Library module "antigravity", when run, opens the xkcd comic "Python". On June 4, 2009, a
function was added into the "antigravity" module that implements the geohashing algorithm (which is inspired by the 426th
xkcd comic, also titled "Geohashing"), according to the commit history of
CPython's git repository. • Inspired by the xkcd comic "Online Communities 2", Slovak artist
Martin Vargic created the "Map of the Internet 1.0." • In 2008, Munroe posted a parody of the
Discovery Channel's
I Love the World advertising campaign on
xkcd, which was later reenacted by
Neil Gaiman,
Wil Wheaton,
Cory Doctorow,
Hank Green, and others. This reenactment was posted to
YouTube with the title "We Love xkcd". • Munroe's 2012 comic "Up-Goer Five" on the
Saturn V rocket inspired the "Up-Goer Five Challenge" for scientists. The original comic described the rocket only using the
one thousand most frequent words in contemporary fiction; in the same way, the challenge is for scientists to describe their journal articles and scientific papers with extremely basic language. More generally, even when not adhering to the original strict list, the comic has been cited as an example of the merits in avoiding too much
jargon that can make scientific papers unreadable to the general public. • The comic "Security", in which two characters plan to bypass a
cryptocurrency owner's encrypted laptop by beating him with a wrench until he gives them the password, is the inspiration for the term "wrench attacks", in which criminals attempt to force a cryptocurrency owner to give them passwords and other information. The term was mentioned following the kidnapping of an Italian man in
New York City.
Academic research In addition, a number of researchers have acknowledged particular
xkcd comics as the source of inspiration for their scientific articles. These academic contributions include: • In 2007, two researchers published an article titled "High Level Internet Scale Traffic Visualization Using Hilbert Curve Mapping". It was inspired by the comic "Map of the Internet". They were inspired by "Significant". • The "Password Strength" comic The second paper was published in 2015, and bears the title "How to Memorize a Random 60-Bit String". • The 2019 paper "Stippling of 2D Scalar Fields" was inspired by "2016 Election Map". • "Dependency" inspired an author to write the article "The Nebraska problem in open source software development". • Two scientific publications were inspired by "Movie Narrative Charts". These articles are named "StoryFlow: Tracking the Evolution of Stories" and "HyperStorylines: Interactively untangling dynamic hypergraphs," with the latter article citing the former. == Politics ==
