[A chart is shown with one horizontal line with 13 ticks (the first larger) and ending in an arrow. There are three labels along the line, at the start in the middle an towards the end before the arrow. Below are two clouds in gray with labels. The first cloud is long and it is getting thinner towards the right. It goes between the first and second label above the chart. The second blob is smaller and of equal thickness and it goes from the last label towards right.

Computer problems are frequent and can be difficult to solve [ citation needed ] . Networking problems in particular can puzzle even seasoned people and sometimes seem to have arbitrary issues causing them. Packets are units of data transfer used in computer networking, and one measure of network performance is lag , the amount of time it takes for data to travel from one point to another (and perhaps back); saying a packet's transmission is 'laggy' means it is unacceptably slow.
Lag in packet transmission and other network performance measures can appear quite random. Just to start with, your ISP may be engaged in traffic shaping, which can do very weird things indeed to your packets (making the first megabyte of a transfer faster than any other, for example); now imagine that your ISP's ISP (usually known as an "Upstream Provider") is engaged in something similar, and you begin to see the scale of the problem. Wireless latency can relate to things as unexpected as where people are standing, what they are touching, the weather, viruses and other system compromises, network activity by other unseen users, and so on. Because humans are wired to perceive patterns, they will find them even in random data , a fallacy that Cueball is probably suffering from here. He variously attributes the network behavior he sees to the packet number being even vs. odd, packet arrival time being before vs. after noon, and packet arrival day being today vs. yesterday. Such a pattern would make sense if it were merely "every other packet" regardless of odd or evenness, but that still leaves unexplained the other "patterns" Cueball is seeing.
These non-existent patterns that Cueball is 'finding' are driving him mad, so much so that he says he believes in ghosts now. The statement of belief in ghosts may be a reference to the intermittent or fluctuating nature of the network issues being caused by mischievous or malevolent spirits. Ghosts generally are not concerned with expressions of belief, but there are some religious traditions that include group clapping and chanting. Many works of fiction depict a future or alternate history where machines are worshiped as gods or spirits , such as the Adeptus Mechanicus of Warhammer 40,000 .  Some of this terminology can be found in present-day IT and other support personnel, including references to " daemons " and " black magic ".  Another possible reference Randall may be making is to the Ghost in the machine , a term describing AI. A third possibility is that Cueball's brain had stopped working, as Randall had suggested in his chart. it may also be a reference to 1316: Inexplicable , in which Megan concludes Cueball's computer is haunted.
The title text continues Cueball's maniacal attempts at self-assurance, with him alluding to J.M. Barrie's play Peter Pan by saying that latency falls every time you "CLAP YOUR HANDS AND SAY YOU BELIEVE". In the play, Peter Pan says, "If you believe in fairies, wave your handkerchiefs and clap your hands." [ actual citation needed ] A more mundane explanation of the network behavior Cueball is experiencing might be that it is random but he's seeing a pattern anyway, or that there is a loose connection or trace and the vibration of clapping and speaking in the vicinity of the equipment in question closes the connection.
Similar superstition regarding computer devices was used previously in 1457: Feedback .
