‘X’s marketing style is irreverent and often acknowledges its community of customers. Product descriptions commonly mock the product, the customer, or ‘X’ itself. In lieu of typical product sales, ‘X’ occasionally offers a blind grab bag officially called "Random Crap." While today its accompanying picture of a paper lunch bag with a question mark has kept its unofficial name "Bag of Crap," (BOC) it was originally dubbed "Bag of Crap" during the early years of the site when a physical bag of some kind (notebook, iomega zipper bags, etc.) was sold with the 1-3 "craps" and was part of what you were buying. Today, the BOC contains at least three "crappy" items and one bag whose value and quality are not guaranteed, but sometimes expensive items are included. The BOC typically triggers millions of order requests and sells out within seconds, causing server lag and usually a crash. During the January 25, 2011 selling, the website received a record 3.1 million requests, and the product was sold out within eight seconds.

In 1987, after turning 16, ‘X’ began hacking under the name "Mendax" . He and two other hackers joined to form a group they named the International Subversives. ‘X’ wrote down the early rules of the subculture: "Don't damage computer systems you break into (including crashing them); don't change the information in those systems (except for altering logs to cover your tracks); and share information". The Personal Democracy Forum said he was "Australia's most famous ethical computer hacker." The Australian Federal Police became aware of this group and set up "Operation Weather" to investigate their hacking. In September 1991 Mendax was discovered in the act of hacking into the Melbourne master terminal of Nortel, the Canadian telecommunications company. In response the Australian Federal Police tapped ‘X's phone lines and subsequently raided his Melbourne home in 1991. He was also reported to have accessed computers belonging to an Australian university, the USAF 7th Command Group in the Pentagon and other organisations, via modem. It took three years to bring the case to court, where he was charged with 31 counts of hacking and related crimes.

"X" describes the situation, idea, or societal condition that ‘Y’ identified as being destructive to the welfare of a free society. It connotes an attitude and a policy of control by propaganda, surveillance, misinformation, denial of truth, and manipulation of the past, including the "unperson" — a person whose past existence is expunged from the public record and memory, practiced by modern repressive governments. Often, this includes the circumstances depicted in his novels, particularly ‘Z’. ‘Y's ideas about personal freedom and state authority developed when he was a British colonial administrator in Burma. He was fascinated by the effect of colonialism on the individual, requiring acceptance of the idea that the colonialist oppressor exists only for the good of the oppressed person and people.

'X’ is an optical illusion first published as a rhomboid in 1832 by Swiss crystallographer ‘Y’. ‘X’ is an ambiguous line drawing. The effect is interesting because each part of the picture is ambiguous by itself, yet the human visual system picks an interpretation of each part that makes the whole consistent. ‘X’ is sometimes used to test computer models of the human visual system to see whether they can arrive at consistent interpretations of the image the same way humans do. Humans do not usually see an inconsistent interpretation of ‘X’. ‘X’ whose edges cross in an inconsistent way is an example of an impossible object. ‘X’ is used in epistemology (the study of knowledge) and provides a counter-attack against naïve realism. Naïve realism (also known as direct or common-sense realism) states that the way we perceive the world is the way the world actually is. ‘X’ seems to disprove this claim because we see one or the other form of a cube, but really, there is no cube there at all: only a two-dimensional drawing of twelve lines. We see something which is not really there, thus (allegedly) disproving naïve realism.

'X' is basically the cube that you draw on paper. It's called a Necker cube.

A resilient, rubber-like material is bonded or otherwise attached to a hard base material which keeps the rubber-like material flat. The base has four rubber-like pads on the opposite side from the resilient material to refrain it from sliding on the surface of a table, for instance. This may be utilized to assist the operation of a cathode ray tube pointer wherein a metal ball is rolled on a hard surface.

The word ‘X’, Latin for "I will please", dates back to a Latin translation of the Bible by Jerome. It was first used in a medicinal context in the 18th century. In 1785 it was defined as a "commonplace method or medicine" and in 1811 it was defined as "any medicine adapted more to please than to benefit the patient", sometimes with a derogatory implication but not with the implication of no effect. ‘X’ were widespread in medicine until the 20th century, and they were sometimes endorsed as necessary deceptions. In 1903 Richard Cabot said that he was brought up to use ‘X’, but he ultimately concluded by saying that "I have not yet found any case in which a lie does not do more harm than good". Beginning in the 1960s, ‘X’ became widely recognized and ‘X’ controlled trials became the norm in the approval of new medications. Later, researchers became interested in understanding ‘X’, rather than just controlling for its effects, and in 2011, a Program in ‘X’ studies was established at the Harvard Medical School.

'X’ is traditionally made from ‘Y’, specifically from a variety of ‘Y’, treated with raw (unboiled) linseed oil. The oil has a protective function. ‘Y’ is used as it is very tough and shock-resistant, not being significantly dented nor splintering on impact at high speed, while also being light in weight. It incorporates a wooden spring design where the handle meets the blade. The current design ‘X’ was the invention in the 1880s of Charles Richardson, a pupil of Brunel and the chief engineer of the Severn railway tunnel.
