Title text: If I'm such a god, why isn't Maru *my* cat?
The comics points out the large number of levels of abstraction working together at any given time in today's computers.
Programs on current computers do not run "directly on hardware". Instead, the hardware (in this case, a processor of the x86-64 architecture) is controlled by the operating system kernel (in this specific case, XNU is the kernel used in Apple-branded devices). Many operating systems offer a standardized interface called POSIX, which wraps the services offered by the different operating systems so that applications do not need to cope with the differences between the operating systems. Darwin is the name of the core set of components on which the Apple's OS X operating system runs. And using this operating system, the user runs the Firefox web browser. However, the browser itself contains further abstraction layers: Gecko is the engine handling the display of web pages on the screen, but in this case, it only allows a separate software, Adobe Flash Player, to render a video requested by the user.
And all of this work is, in this case, done only because the user wanted to watch a funny cat Flash video on the Internet; which makes the user feel like he is a god.
The title text refers to Maru the cat, a cat who became very popular on YouTube for, among other things, jumping into a box. Cueball questions his god-like capabilities by wondering why can't he own Maru.
Flash was officially discontinued from all operating systems and browsers in December 2020. Soon, getting this joke without reading explain xkcd will date you considerably.
- [Cueball is sitting at a computer.]
- An x64 processor is screaming along at billions of cycles per second to run the XNU kernel, which is frantically working through all the POSIX-specified abstraction to create the Darwin system underlying OS X, which in turn is straining itself to run Firefox and its Gecko renderer, which creates a Flash object which renders dozens of video frames every second
- because I wanted to see a cat jump into a box and fall over.
- I am a god.
