I'm really not assuming too much at all.

Have you ever been on slashdot?

I mean, it's hard to tell how long you've been around so maybe you're not aware of the context here.

I will give slackware (and gentoo and alpine) due consideration. ...ank

Why not use: "systemctl stop "?

Thanks for the helpful hint. I didn't know about that until now. (now I'll have to figure out what name my display manager is known by to systemd -- is there no end to the rabbit hole?) I'm still not sure, though, why systemd couldn't have left backward-compatible aliases around -- even if they spit out 20 caveats when you use them, including what commands I probably want to run instead. The command you suggested is shorter and more reasonable than what I figured out to use, but it's still way wordier than "killall gdm" or "telinit 3".

Also, I'm posting as me. Can you please do the same?

Also, I'm still not happy adopting an init system whose authors treat corruption of the journal as a "won't fix". Not happy at all. That's not an attitude that inspires confidence and I don't understand how any putative improvements in other areas out-weigh it, never mind the silly ones I've heard like "lower PID numbers!", "lower socket numbers!": yeah! as if that sort of stuff ever mattered.

To others: slackware will get my due consideration as will gentoo and alpine. Don't count on BSD escaping this nonsense, though. I understand Apple is pressuring Darwin to adopt a systemd like system there, too. Why, oh why!!?

You don;t seem to understand that "best" in this context doesn't refer to a literal superlative material, but to the best material currently available from a glass manufacturer at the time the product was made.

Ah yes, that well known Corning-hate on slashdot, with the frequent trope of being excited to upgrade your corning product on a short, repeating cycle like sheep.

I hardly think the original coward's target was non-obvious.

Today I learned that people with opinions counter to anonymous cowards are Apple employees or stockholders of Apple. Man, there must be a lot of them!

About time Apple did what? Made their phones deliberately out of the best material available at the time and now out of a subsequently even better material made by a third party supplier that they don't control?

What did you think they are "about timing"? Making new phones out of a material that has only just been announced?

I'm not following.

What do you mean? I was directly replying to a brave coward who went for a cheap apple bash.

Is replying to that comment with an opposing opinion "getting defensive"? Isn't this a discussion forum?

Oh, right. I understand.

News just in! Products get better incrementally, somehow only controversial when Apple does it. Film at 11.

Yes you can.

except in a VERY black way.

Don't wait five years. I find systemd to be more and more annoying every day. The closest things I can find to "telinit 3" and "telinit 5", "systemctl isolate mulit-user.target" and "systemctl isolate graphical.target" (and talk about convoluted command lines!) can't be counted on to stop and restart the GUI part of my arch box.

Give me back my sysvinit. It may have looked crufty to some but it worked. systemd? meh

I'm running arch. Arch moved to systemd before I understood the issues at stake. I feel the systemd pain every day. I'm trying to get multi-head with nouveau working (a different set of pain, that I'll probably just switch to nvidia blobs to get around -- unless someone can point me where I want to be -- but I digress)

...and I don't understand why "systemctl isolate multi-user.target" vs. "systemctl isolate graphical.target" [try explaining THAT pair of command lines to start with] can't be expected to be as dependable as "telinit 3" vs. "telinit 5".

If I couldn't ssh into the box from somewhere else regularly, I'd be hitting the Big Switch a lot and we all know how well file systems take that kind of shenanigans.

I don't need to wait five years to hate systemd. I hate it more and more every day. My feelings do not extend to the authors -- as humans, they deserve my compassion and (in this case) pity. But I hate their software with a passion that grows more intense by the day. This is a sad day for Debian, it was one of the places I was thinking of escaping to.

The Ideal Gas Law determines what happens to a gas under pressure: PV = nRT

Pressure is proportional to volume, so if you compress a gas it shrinks in volume until eventually it liquefies - but the point at which it does depends on the phase diagram for that particular gas. The properties change depending on the molecules.

If you release pressure quickly then it expands very rapidly and cools down. This is a function of thermodynamics. Similarly, if you compress a gas it will heat up for the same reason. This is common to all gases. Jamming the molecules in ever tighter will increase the temperature. Your air compressor heats up when it is compressing air because of this. When you let the pressure out, the temperature of the air drops rapidly.

Where things like hydrogen are special is that you can't liquefy them by simply pressurising it. You need to cool it down too - the triple point of hydrogen is about 22 K and the critical point is about 32 K - hydrogen simply can not be a liquid at any pressure unless the temperature is between these two values (22 K is -251 C or -420 F - cryogenically cold temperatures).

Any gas under pressure is a hazard - cylinders of nitrogen are pressurised to 300 bar and if one of those ruptures you're in a world of hurt, despite the fact that nitrogen itself is inert, but we routinely handle high pressure gasses in industrial and commercial environments. You take more precautions with a hydrogen cylinder (or any cylinder of flammable gas), but the handling procedures for flammables overlap a lot with the non-flammables like nitrogen and argon.

You think hydrogen stored for use in commercial fuel cell vehicles is stored cryogenically.

Cute.

I can see why you didn't log in.
