This is wild - somebody did a deep dive into the real stories behind this famous XKCD: sheets.works/data-viz/hol...
an XKCD comic showing a precariously assembled tower of blocks. much is labelled "all modern digital infrastructure." a thin leg down at the bottom is labelled "A project some random person in Nebraska has been thanklessly maintaining since 2003."

Me: oh wow, this shop has everything my heart desires!

Spooky shopkeeper: yes, I will warn you... every item comes with a price.

Me: yes, I know how shops work

Spooky Shopkeeper: The price may be more than you expect to pay.

Me: Yes, I know how US taxes work, too.

Shopkeeper, increasingly exasperated: I'm trying to tell you that I'm evil and offering these wares with no regard for the harm they will do!

Me, also increasingly exasperated: I know what capitalism is too goddammit

Discworld QOTD, from Night Watch
But the helmet has gold decoration, and the bespoke armorers had made a new gleaming breastplate with useless gold ornamentation on it. Sam Vimes felt like a class traitor every time he wore it. He hated being thought of as one of those people that work stupid ornamental armor. It was gilt by association.

So, this guy has a track record for help with something unglamorous but *really* useful. The ability to dig in well and quickly saves so much else. If you want to help individually this is one of the most efficient ways to do it.

The image is of a four panel comic.
The title reads, "Suddenly Finding A New Obsession".
In the first panel we see Sarah, the protagonist, in front of her computer. She has a bored expression on her face.
In the second panel we zoom in on her face. She looks suddenly alert.
In the third panel we zoom in even closer on her face. Her eyes and mouth are wide open in intrigue.
In the fourth panel we zoom out and see Sarah in front of her computer again, but this time she is dressed in a frog costume, surrounded by frog toys, and has an "I heart frogs" poster behind her.

Some changes to the XIV Onslaught - 45 DP, with built-in Armored Weapon Mounts (which also gives a "free" s-mod), and the missile mounts changed to composite for more potential Big (well, medium) Guns. (Seems like a heavy MG/elite point defense + other range-boosters build might be fun, hmm.)

Three teenagers in a car. Something has gone TERRIBLY wrong as you can see their skeletons through their skin. The first kid looks at his hands and says, "Oh this is BAD." The second is furious as she shouts, "WHERE DID OUR MOLECULES GO, AUGIE? WE NEED OUR MOLECULES?" The third teenager, panicking while driving, hits a button on the ceiling.

The original American monitors apart, that's basically what's going on. Generally the guns were going spare (as items with a long lead time and a need for extras, there were often big guns in stock) and just needed a convenient, preferably cheap, hull to plonk them on and carry them where needed.

Any model that uses game theory to analyze what decisions are rational, but ignores that the expected value of money is *not linear* for most humans, most of the time, is not a good model for the real world.

If Internet ads were like ads in magazines -- they didn't track you, didn't run arbitrary malware on your computer, didn't do annoying video autoplay and cover up the thing you're trying to read -- nobody would use an ad-blocker. If sites don't want us using them, they do have a choice.
