[[Cueball]]'s cousin decides to install Linux on her new PC, and calls Cueball, whom she views as her personal Linux expert. The overarching joke revolves around the fact that Linux, especially home PC-based GNU/Linux, is much more often used as a "hobby" OS, as compared against a "productivity" OS such as {{w|Windows}} or {{w|macOS}}. Large numbers of people use Windows or Mac by default, because it came with their computer hardware when they bought it, and it already had the software suite they wanted to use installed along with it. Linux, on the other hand, rarely comes pre-installed on PC hardware and generally must be deliberately chosen and acquired; and while it can be set up to achieve efficient and productive workflow in virtually any area on PCs, because it often must be consciously selected, installed, and configured by users, it tends to either attract or, in a few cases, create individuals who take disproportionate pleasure in, and derive self-identification from, hacking the operating system itself. Thus, many people who are {{w|Linux}} {{w|Hacker (hobbyist)|enthusiasts}} began by not really knowing anything about it other than that it's {{w|Gratis|free of cost}}, but the process of actually building Linux on their machines gradually led them to take an increasing interest in it, which the comic humorously likens to substance addiction.

Xorg (officially {{w|X.Org Server|X.Org}}) is an implementation of the X Window System, a program responsible for the graphical display used on Linux.

In the third panel, we see that the cousin has had new problems.  Though she likely has been able to fix Xorg, she is now having problems with Ubuntu's auto-configuration tools.  She suggests that she is considering switching to a more advanced Linux distro in order to sidestep the failing autoconfig issues. A Linux "distro" (distribution) is a suite of tools and applications that provides a specific user experience on top of the core Linux operating system.

In the fourth panel there is a strong implication that the cousin has indeed switched to Gentoo because a hallmark of that distribution is the kernel (the basic core of the operating system) must be compiled from source code upon installation.  Source code is a computer program expressed in an somewhat human-readable format, often simply as text. However, source code cannot be run directly by a computer, and instead needs to be "compiled" into low level machine instructions the computer can understand. This means that with Gentoo, instead of downloading an already functional Linux system to install and run, users download the source code for the system, customize it to their own needs, then compile the code into a runnable version of the OS, all before they can begin to use the system. The cousin has been forced to do this because whatever her problem is, the solution required a customized kernel.  This could include needing the kernel to be compiled in a non-standard way not supported by more mainstream distros, incorporating experimental third party code into the kernel or modifying the kernel herself to fix the problem.  Compiling a kernel with the aforementioned modifications is a tricky affair since any mistake or oversight can render the kernel, and thus the computer, non-functional.  If a mistake is made or the custom kernel does not fix her problem  the kernel needs to be compiled anew.  The fourth panel also implies the cousin has been stuck in a {{w|Trial and error}} loop, compiling the kernel over and over again for the better part of 6 weeks in an attempt to fix her problem.

To many such advanced users, their installation of Linux is like a hobby sports car: A never-ending project, constantly tweaked and cleaned and adjusted to improve performance, that spends far more time sitting around with its hood open than actually being used for its ostensible purpose.  However, for more typical users who are interested in a functional computer system instead of a toy or project system, Gentoo can be highly frustrating or plainly unusable.  By week 12, Cueball's cousin is likely suffering from the {{w|Sunk cost fallacy}}, in that she believes that since she has put in so much time she needs to see it through.  She might also be optimistically underestimating how much additional work will be required since at each point Linux does at least offer potential solutions due to its customizability.  Finally there could be an element of {{w|Target fixation}}, in that the cousin has become so focused on the problem, she has forgotten about her original plans for the computer or that Windows is still an option.

Similarly, in the fifth panel, Randall riffs on the old anti-drug message "Parents, talk to your kids about drugs before someone else does," with the meaning being if a responsible adult does not educate their kids about the dangers of drugs (or Linux), then someone else (likely a peer) might convince them that drugs (or Linux) is a good idea.  There is an additional call to the theory of {{w|gateway drugs}}, where mild drugs like alcohol or cannabis will lead to harder drugs like cocaine and heroin.  In the comic, Cueball's cousin starts out with Ubuntu, a "gateway" version of Linux, which leads to Gentoo, a harder, more niche version, with the end result being her vanishing for weeks inside her house, compiling her kernel, like a junkie hopelessly hooked on drugs.

Explanation[edit]

Cueball's cousin decides to install Linux on her new PC, and calls Cueball, whom she views as her personal Linux expert. The overarching joke revolves around the fact that Linux, especially home PC-based GNU/Linux, was (at the time of this comic's publication in 2008) much more often used as a "hobby" OS, as compared against a "productivity" OS such as Windows or macOS. Large numbers of people use Windows or Mac by default, because it came with their computer hardware when they bought it, and it already had the software suite they wanted to use installed along with it. Linux, on the other hand, rarely comes pre-installed on PC hardware and generally must be deliberately chosen and acquired. While it can be set up to achieve efficient and productive workflow in virtually any area on PCs, because it often must be consciously selected, installed, and configured by users, it tends to either attract or, in a few cases, create individuals who take disproportionate pleasure in, and derive self-identification from, hacking the operating system itself. Thus, many people who are Linux enthusiasts began by not really knowing anything about it other than that it's free of cost, but the process of actually building Linux on their machines gradually led them to take an increasing interest in it, which the comic humorously likens to substance addiction.

Xorg (officially X.Org) is an implementation of the X Window System, a program responsible for the graphical display used on Linux. If it has configuration problems, which was quite common with some video card drivers back in 2008 (especially those for ATI Radeon cards), it is often difficult and/or painful to fix (see 963: X11). Man pages are manual pages for Unix-based operating systems and software, usually accessible online but also bundled with the software itself. Considered helpful and clear by the sorts of advanced computer users who typically run Linux, the text-only documentation can seem inaccessible for less-technical users. Here, the joke starts to build in that Cueball's cousin, a computer novice who just wanted something to work out of the box, is now having to learn how to understand Linux documentation in order to fix her ongoing Xorg problem (likely an inability to start a graphical environment, something a novice user would depend on).

In the third panel, we see that the cousin has had new problems. Though she likely has been able to fix Xorg, she is now having problems with Ubuntu's auto-configuration tools. She suggests that she is considering switching to a more advanced Linux distro in order to sidestep the failing autoconfig issues. A Linux "distro" (distribution) is a suite of tools and applications that provides a specific user experience on top of the core Linux operating system. Each distro has a different look and feel and different feature sets and design philosophies. Ubuntu is a very popular "beginner" version of Linux, designed to "just work" and be familiar and usable to people fresh out of Windows. Debian is a popular but somewhat more "advanced," traditionally "Unix-like", distro, with a huge and diverse base of supported software that generally requires more Linux know-how to configure and use. In fact, Ubuntu is based on Debian, and under the hood they have similar features, so that it would not be considered much of a leap for a competent Ubuntu user to switch. Gentoo, on the other hand, is a very advanced distro allowing for extreme customization and optimization, but requiring extensive install and setup time. It is generally considered to be complex and beginner-unfriendly (to the point that its difficulty has become somewhat memetic in the Linux world), a trade-off for providing a powerful and versatile set of tools for advanced system hacking.

Transcript[edit]

Linux: A True Story:
[Cueball talks on a cell phone.]
Week One:
Cousin: Hey, it's your cousin. I got a new computer but don't want Windows. Can you help me install "Linux"?
Cueball: Sure.
[Cueball's cousin sits in an office chair with her laptop on her lap. She is on the phone.]
Week Two:
Cousin: It says my XORG is broken. What's an "XORG"? Where can I look that up?
Cueball: Hmm, lemme show you man pages.
[Cueball's cousin crouches on the floor with the laptop on her lap. She is still on the phone.]
Week Six:
Cousin: Due to auto-config issues, I'm leaving Ubuntu for Debian.
Cueball: Uh.
Cousin: Or Gentoo.
Cueball: Uh oh.
[Cueball's cousin lies on her stomach with the laptop on the floor. On the floor are several pieces of paper and a book. Cueball stands to her left.]
Week Twelve:
Cueball: You haven't answered your phone in days.
Cousin: Can't sleep. Must compile kernel.
Cueball: I'm too late.
[Box with text:]
Parents: talk to your kids about Linux... Before somebody else does.

Discussion

Isn't 'Talk to your kids about...' from a famous Unilever ad? 101.174.52.183 09:47, 2 June 2013 (UTC)

Is this Megan? Her hair seems awfully curly and it says she's his cousin. Is there an official transcript? Theo (talk) 20:46, 14 August 2013 (UTC)

Official transcripts, if they do exist, do not contain names in general. These names are just an invention by some communities like this wiki. So, if you have a better stick figure which would match her, talk about this.--Dgbrt (talk) 21:16, 14 August 2013 (UTC)
She is clearly not Megan. I propose to call her cousin. Xhfz (talk) 22:20, 13 October 2013 (UTC)
There exists an official transcript for each comic, available to see in the page's source code. According to a comment in 1037:_Umwelt, Randall does apparently not type those, but is seemingly done by Davean, his friend maintaining the server. (Note: this is just a guess) Vgr (talk) 11:22, 22 October 2013 (UTC)
I don't think that this is Megan either. I propose to call her Alice, though, in reference to cryptography. Official.xian (talk) 19:46, 10 July 2014 (UTC)


I think we're all forgetting something very important here: It's a true story, therefore she has a real name. If we really wanted her correct name, we'd be pestering Randall for it. Anonymous 23:26, 18 August 2014 (UTC)
And since it's a true story Cueball here's probably meant to be Randall himself. Elektrizikekswerk (talk) 08:57, 14 November 2014 (UTC)
And the hair not reminiscent of Megan.173.245.55.25 17:26, 18 March 2015 (UTC)
Then why has nobody fixed it to say Cousin instead of Megan?... 173.245.54.166 19:42, 3 April 2015 (UTC)
Done. I'm not sure abiut the hyperlinks though, if they're supposed to be on every reference to curball then someone shoulf add those. Bbruzzo (talk) 15:28, 26 August 2015 (UTC)


The last paragraph is taking quite a leap. While she has obviously learned over the 3 months, we have no idea if she is actually building her kernel in a critical and meaningful way. Does not fit with actual comic. flewk (talk) 19:28, 28 December 2015 (UTC)

The part where it says man pages use simple unambiguous language made me laughThaledison (talk) 17:59, 26 January 2016 (UTC)

It's called mansplaining for a reason... 172.68.59.186 (talk) (please sign your comments with ~~~~)

Shouldn't it be explained outright that Randall is Cueball (since title text confirms it's a true story)? -- [[User:{{{1}}}|{{{1}}}]] ([[User talk:{{{1}}}|talk]]) (please sign your comments with ~~~~)

The [https://www.explainxkcd.com/wiki/index.php?title=456:_Cautionary&oldid=226935 "There's no learning curve..." edit" is not quite right. Though all Man Pages should be accessible, do you remember the first time you came across something like:

URI       = scheme ":" hier-part [ "?" query ] [ "#" fragment ]
hier-part = "//" authority path-abempty / path-absolute / path-rootless / path-empty

...and wondered what it meant, or how to parse it? Some of the Man Pages out there are even more technically-inclined, presupposing prior knowledge (or where to go to get it), which may not be their intended philosophy but is nonetheless a fact. Not changing anything, but pointing this out. 141.101.99.20 13:22, 12 February 2022 (UTC)
