AFFF is used in far more than just military bases. Outside of the USA, AFFF extinguishers, small vehicle/building hazard suppression systems, etc. are much more common.
AFFF is being/has been phased out pretty much everywhere in the first world. There is still plenty of it around though - disposing of, and then filling with fluorine free foam can be an expensive process.
Personally, it’s about $10/litre to dispose of. Regardless of concentration. So properly rinsing out old equipment is expensive. But I know the situation differs by country, and what’s deemed “acceptable” varies too.
Powder doesn’t contain fluorinated compounds, at least to my knowledge. The role of fluorosurfactants is in increased wetting and emulsifying with hydrocarbons. Not really applicable to a dry agent.
Many oil filters these days are accessible from the top of the engine, and IME it’s possible to get under many SUVs/CUVs/trucks far enough to remove the filter/bung without lifting anyway.
A set of drive-on ramps makes it kind of a non issue either way
If I had to guess, Alpine is a very popular choice for building container images in Docker/Kubernetes/whatever the new hotness is since I last worked with containers. Mostly because the aforementioned small size and low overhead add up if you’re at any sort of scale (even one instance on top of your desktop OS).
If you’re wanting to containerise the program, maybe it’s less resource intensive to add those things to Alpine than to run another distro with more support? Obviously only speculation
Doesn't Kubernetes deduplicate layers by hash? I thought the key to minimizing overhead was standardizing on a limited set of images across everything you'll be running on the same host.
Just from reading HN it seems like Alpine had a brief fad a few years ago but never got much traction.
the underlying container runtime (usually containerd) will dedupe shared layers, but there's a lot of things you don't get to directly control, like third party apps, and the bottleneck when spinning up new nodes is real. Plus, envs where there isn't that much caching, like CI.
Espressif has also capitalised on this trend with the ESP32, having cheap (~$10) official dev boards available at or before the launch of a new Esp32 model
I found it’s a form of jargon, and once you know more about the field, it becomes much clearer.
Before I started working out at all, I found it really hard to follow any workout instructions (even videos). I couldn’t tell if what I was doing felt right or if my form was off in some important way.
After a few sessions with a personal trainer/physical therapist, and just getting comfortable with the sensations and movements, I found it much easier to figure out what I’m supposed to be doing from an instruction. I had more of the building blocks that I knew were correct already.
Text is still inherently a difficult way to instruct movements though.
You’ll be missing out on some experiences for sure. Would it be a net positive? Probably not. But you really can’t quite comprehend the feelings you’re missing out on.
There might be tangential things you don’t experience too, places you’ll never go, and people you’ll never meet.
But yes Phos-check isn’t that
