A hacker is a person skilled in information technology who achieves goals by non-standard means. The term has become associated in popular culture with a security hacker – someone with knowledge of bugs or exploits to break into computer systems and access data which would otherwise be inaccessible to them. In a positive connotation, though, hacking can also be utilized by legitimate figures in legal situations. For example, law enforcement agencies sometimes use hacking techniques to collect evidence on criminals and other malicious actors. This could include using anonymity tools to mask their identities online and pose as criminals.

23, original German title: 23 – Nichts ist so wie es scheint is a 1998 German drama thriller film about young hacker Karl Koch, who died on 23 May 1989, a presumed suicide. It was directed by Hans-Christian Schmid, who also participated in screenwriting. The title derives from the protagonist's obsession with the number 23, a phenomenon often described as apophenia. Although the film was well received by critics and audiences, its accuracy has been vocally disputed by several witnesses to the real-life events on which it was based. Schmid subsequently co-authored a book that tells the story of the making of 23 and also details the differences between the movie and the actual main events.

Life in the real world is far more interesting, far more important, far richer, than anything you'll ever find on a computer screen." Stoll later acknowledged that the book was a mistake.
Numberphile is an educational YouTube channel featuring videos that explore topics from a variety of fields of mathematics. In the early days of the channel, each video focused on a specific number, but the channel has since expanded its scope, featuring videos on more advanced mathematical concepts such as Fermat's Last Theorem, the Riemann hypothesis and Kruskal's tree theorem. The videos are produced by Brady Haran, a former BBC video journalist and creator of Periodic Videos, Sixty Symbols, and several other YouTube channels. Videos on the channel feature several university professors, maths communicators and famous mathematicians.
A cuckoo's egg is a metaphor for brood parasitism, where a parasitic bird deposits its egg into a host's nest, which then incubates and feeds the chick that hatches, even at the expense of its own offspring. That original biological meaning has been extended to other uses, including one which references spyware and other pieces of malware.
