I can’t give an authorative answer (not my domain), but I think there are two ways these types of things are done.

First is just observing the page or service as an external entity; basically requesting a page or hitting an endpoint, and just tracking whether you get a response (if not, it must be down), or for measuring load level in a very naive way, track the response time. This is easy in the sense that you need no special access to the target. But it’s also limited in its accuracy.

Second way, like what your github example is doing, is having access to special api endpoints for (or direct access to) performance metrics. Since the github status page is literally ran by Github, they obviously have easy access to any metric they could want. They probably (certainly) run services whose entire job is to produce reliable data for their status page.

The minute details of each of these options is pretty open ended; many ways to do it.

Just my 5¢ as a non-web developer.

Lua.

Don’t call the ambulance, it’s too late for me

I know it won’t happen, but I keep imagining CDDA getting the “Steam” treatment ala Dwarf Fortress. Both games are amazing… Should play CDDA again myself. Always such a pain to remember HOW to play though, and by the time my muscle memory gets good enough that I can actually fluidly play the game instead of staring at keybinds, I’ve kinda run out of gas 😄

You are totally correct, but I feel like pointing out that a surprising number of games use the 4k texture nomenclature in a totally illogical way; they label it 4k because it’s meant to look good on a 4k screen, not because the texture itself is at that resolution (or any loosely related resolution).

Which is itself really annoying. But I guess less savvy crowd might not actually understand what ‘real’ 4k textures even refer to?

Man. That was a good series. Not sure if I can watch it again now, though…

Seeing as it’s their river and they are operating it, not sure what exactly you want as evidence.

While true that the x nm nomenclature doesn’t match physical feature size anymore, it’s definitely not just marketing bs. The process nodes are very significant and very (very) challenging technological steps, that yield power efficiency gains in the dozens of % usually.
