Theft Quadrants
TinyURL was the most popular link shortener for long enough that it made it into a lot of printed publications. I wonder what year the domain will finally lapse and get picked up by a porn site.

Explanation

Ambox notice.png This explanation may be incomplete or incorrect: How difficult would it be to steal TinyURL, really? Is it a real problem?

This is a "Eisenhower box" comparing how difficult it is to steal a specified thing with the severity of the theft.

It is very hard to steal nuclear launch codes. They are protected by many layers of federal security. That's a good thing, too, since if they were stolen, they could be used to start a nuclear war, which would be a very bad thing.[citation needed]

It is also hard to steal the crown jewels, since they are protected by a complex security system. But if they were stolen, it wouldn't be so bad for most people.

It wouldn't be too hard to steal the Wienermobile (a car shaped like a hot-dog, advertising the Oscar Mayer brand), and there would be little consequence at all if it were stolen.

However, it wouldn't be hard (or at least, not as hard as stealing nuclear launch codes or the crown jewels) to steal the tinyurl.com domain name, but the consequences of that could be significant.

TinyURL offer a url shortening service. They provide short URLs that redirect to long ones. This is useful if you want to write down a very long URL as it saves typing and is more accurate. Other companies including bit.ly offer a similar service, as do Google and Twitter. TinyURL was, for a while, the most popular of these URL shortening services. If their domain name were stolen, all the redirects from short URLs could be changed to forward traffic to sites hosting, for example, malware. This would have significant effects on a large number of people, because TinyURL is used in many places both online and (as the title text notes) even sometimes offline.

Domain hijacking is relatively common. If a cracker can obtain personal information about the domain owner, they can impersonate them to the domain registrar, and obtain control of the domain, and with that control defraud a large number of people. [Well-known examples?]

As the title text notes, sites can be particularly vulnerable if they do not maintain their web site, as the registrar is free then to sell the same domain to any third party. A whois search as of June 2016 finds that the tinyurl.com domain is next due for renewal in June 2018.

Randall has written about stealing the Wienermobile before in 935: Missed Connections.

  • List of all comics contains a complete table of all xkcd comics so far and the corresponding explanations. The red links (like this) are missing explanations. Feel free to help out by creating them!

Rules

Don't be a jerk. There are a lot of comics that don't have set in stone explanations, feel free to put multiple interpretations in the wiki page for each comic.

If you want to talk about a specific comic, use its discussion page.
