> If I need a universal lubricant that is readily available and cheap, I just use used motor oil.
Why? Used motor oil is, well, used. It contains metal particles from the engine and combustion byproducts, which is why it was replaced in the first place. Granted, most lubrication applications aren't the marvels of precision parts moving at high speed that a modern engine is so can probably make do with poorer oil, but still.
You can buy industrial lubricants in bulk for pretty cheap so that unless you use huge quantities of it, it shouldn't make much difference.
As an aside, my aunt's husband worked more or less his entire career in a heavy truck repair shop. And he had an oil burner heating his house (you can see where this is going, eh?). So he got used engine oil for free, the shop was happy to get rid of it as disposing of it properly cost money. I think burning used engine oil was illegal already back then due to the pollution, and nowadays I think they have some government mandated accounting system to ensure that the same amount of oil is sent to proper recycling as comes in.
You're right about getting industrial lubricants in bulk for cheap. But I don't need 55 gallons of lubricant. I'd never use it all nor do I want to store it.
Used engine oil isn't really suitable for lubricating an engine anymore but it's fine for a temporary lubricant of a drill bit, some random hinge on a gate, or stubborn bushing on a piece of equipment. Engine oil is only really replaced on an engine because at some point it degrades enough that things like oil film bearings in the crankshaft would start to fail. A bushing on something like a small dump trailer doesn't rotate at 2300 rpm.

Well, the corollary to that is that if it's just small case usage then if you buy a 1L bottle of some general purpose lubrication oil for, say, $5, then it doesn't really matter in the grand scheme of things that the price/L is a lot higher than if you buy an entire drum of the stuff. ;-)

Fair enough. I guess I just don't see the benefit here vs just having some bottle of cheap unused lubricant. Except if used engine oil is the only thing you happen to have at hand.
At least soot from ships is an issue in high latitudes, as it turns out that the soot reduces the albedo of the ice and it thus has an outsized global warming impact.
The podman kube support? It provides similar functionality as docker-compose, using a yaml file which is a subset of the Kubernetes pod definition syntax.
Then you can just create a few line systemd unit definition, and it integrates as a normal systemd unit, with logs visible via journalctl etc.
> Note: The kube commands in podman focus on simplifying the process of moving containers from podman to a Kubernetes environment and from a Kubernetes environment back to podman.
I'll give it a try, but I'm starting to understand why there is so little use of podman among amateurs.
Personally, I am not interested in kubernetes, just podman for single-node use case. What the kube YAML does for this use case is provide a way to declare a multi-container application.
The podman documentation pages I have found most helpful for this use case are podman-kube-generate (generate kube YAML from an already running pod), podman-kube-play (run the kube manually) and podman-systemd.unit (run the kube as a service).
Edit: I should also mention that there are pod units (which don't require the use of kube YAML) but I skipped over them because they do not support podmans auto-update feature.
You can actually count to 12 on your fingers using one hand. Use the thumb as a pointer, then for each of your other fingers you have three joints. So 3*4=12.
It's hard to actually count using more than 4 bits/hand though. The quickest methods that require the least dexterity are those that count the knuckles (which are actually used in some counting traditions, unlike binary finger-counting).
> There were many older models of BMW that had an electric water pump. If that sounds silly, well, it is. And it failed frequently and was again, very difficult to replace.
On the face of it, it's not actually a bad idea. The electric pump can run at an optimal speed regardless of engine rpm. This means the pump can be downsized, because otherwise if it's driven directly from the engine it'd have to be sized for the worst case scenario of low rpm and high load.
Same reason why many vehicles nowadays have electric radiator fans rather than driven directly from the crankshaft like in the "good ol' days". (Of course with transverse mounted engines a crankshaft driven fan doesn't really work either, so that's another big reason to go for an electric fan.)
Now, of course this concept can be badly implemented, just like any other part of the design.
As much as I'm gung-ho about the world electrifying transport, I agree with you here. Those Porsche SUV's just look awful, whatever the drivetrain. If I'm gonna splurge on a Porsche, I'll want the real thing. And if I don't want a 911, well there are a lot of other brands making more sensible vehicles.
(Of course, if a lot of other people share my extremist views, that's pretty bad for Porsche the company. They likely can't survive just producing 911's. Oh well, I'm not here for corporate charity anyway.)
Unfortunately children playing in the yard have ample time to get behind the car between you checking it, entering the car, starting it, and reversing.
Yes, in principle one could take whatever other measures necessary to prevent such accidents. In reality, backup cameras save lives. Just like seatbelts, anti-lock brakes, crash safety standards, and other safety features that "Real Manly Drivers" protested against back in the day.

In "The Great Leap Forward" they killed tens of millions of their own. Granted, that was a long time ago, but while the current leaders may be wiser little suggests they aren't as ruthless.
