Prevent the screen from blanking under GNOME+Wayland while a video is playing

Prevent the screen from blanking while a video is playing.
This script is a workaround for the GNOME+Wayland issue documented in the
[Disabling Screensaver] section of the mpv manual, and depends on
gnome-session-inhibit (usually provided by the gnome-session package) to set up
the inhibitors.

Think twice about Wayland. It breaks everything!

Think twice before abandoning Xorg. Wayland breaks everything!

Hence, if you are interested in existing applications to "just work" without the need for adjustments, then you may be better off avoiding Wayland.

Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating everyone else (e.g., people using just an X11 window manager or something like GNUstep) in the process.

The Wayland project seems to operate like they were starting a greenfield project, whereas at the same time they try to position Wayland as "the X11 successor", which would clearly require a lot of thought about not breaking, or at least providing a smooth upgrade path for, existing software.

In fact, it is merely an incompatible alternative, and not e

GJS & SpiderMonkey Garbage Collector Heaps

Generally speaking, SpiderMonkey implements a mark-and-sweep garbage collector, although it employs a number of strategies including generational collection (with nursery and tenured regions), incremental collection, arena compacting and others.

This a brief overview of the structure of SpiderMonkey garbage collector heaps with some additional notes on GJS particulars. This isn't an exhaustive article on garbage collection or SpiderMonkey internals, only a reasonably thorough
