angiosperm··on Ubuntu 24.04 (and Debian) removed libsystemd from SSH server dependencies
Seems like the code they added in place of the call to the huge libsystemd should be in a little library that all the other programs that need to perform systemd_notify may use. Seems like systemd should ship that library, or split out the part of their massive (789981 bytes in the text section) library that does just that bit. And probably split out other parts.

Conceded. Anyway the Romans were unpleasant neighbors and worse hosts. But I do not credit Christianity for recognition of rights to dignity and freedom. The Church has much more commonly been a supporter of oppression, starting as the official religious organ of the Roman Empire itsel. Only in recent centuries have breakaway sects adopted enlightenment values from secular culture.
angiosperm··on First languages of North America traced back to two groups from Siberia

The most interesting secondary information I got from this vid is that there are dozens of mammoth sites in North America that have not been excavated because they are considered too old to be potential human cultural sites, or because no interesting stone tools were found.

The next was that the butchers of this mammoth lacked the sophisticated stone tool technology later migrations brought in. Thus, not finding stone tools does not disqualify a site as cultural. Apparently the stone tool technology was not known to the south Asian maritime population that first settled the Americas, but was brought in by the Siberian overland population.

Mammoths and mastodons might be the only North American extinctions we can reliably blame on early Americans. The rest of the extinct macrofauna (30+ genera) fell to the end-Pleistocene comet strike and continent-spanning wildfires, or follow-on effects.

It is interesting that this work places those languages entering only ~5kya, many millennia after the other language families were long established. Their success establishing residence particularly in the Pacific Northwest is remarkable. How they achieved it might never be known, but maybe some complex of technological innovations they brought enabled it.

TIL about the Hartley Mammoth butchery site, 37kybp in New Mexico, via offhand mention in the paper. It will be hard for naysayers to discount it, given so many details seen almost exclusively in human contexts.

Of course there would be no detectable linguistic remnants of these people after so long, so their place in the landscape of migrations may never be established.

I understand from this that you consider coercive interactions and slavery to be such a normal part of your world as to be unworthy of comment.

Pretending that people of the time bearing under the crushing burden of slavery did not suffer for it is the culture-washing. They were fully aware of their status, and would have spit on your complaint.

The fresco painters probably cycled through Rome to pick up current fashions, then circulated through outlying towns to meet demand for capital styles. A top politician could easily have afforded the best painters, if he cared.

The "narrative that this was created by slaves" is just a fact of history. If you don't like how history was, you may direct your attention elsewhere. Ranting about somebody mentioning facts of history you prefer to avoid thinking about is disconnected from life.

By "correct" here you only mean fashionable. Either approach works. Each has its merits and its costs.

Any big enough system will have parts that are most sensibly built object-oriented, and other parts that are more reasonably functional, plus anything else you can think of.

Civilization as we understand it was already thousands of years old, then, and actually expressive art from the period is easy to find.

These frescoes were painted at great expense on behalf of an elite figure. He could afford to have expressive art if he cared enough to demand it, and was perceptive enough to recognize whether he had it. Evidently he didn't, or wasn't.

You are the only one here enforcing a personal agenda. I have as much right to call attention to the coercivity manifest in all the images as you would to call attention to their color scheme. But instead of calling attention to the color scheme or whatever interests you, you try to shame me for saying what I notice about them.

The alley was the way to the slaves' rooms, so supplies and slaves would not need to traipse through the manor. The slaves probably slept right there, or in rooms above got to by ladders.

They probably traveled from city to city. They certainly carried clip art catalogs, and had painted each scene many times over. It wasn't art, it was decoration.

They were topics considered more appropriate for a social setting. That they were really about rape and kidnapping was probably not seen as notable; they are just familiar furnishings of a culture founded and maintained on armed compulsion. Nobody but the gods have any freedom, and the gods are bored children.

Slaves did anything in Roman society. Skilled workers from conquered places were enslaved. Slaves apprenticed under them. Slaves even ran all the government offices, and some got rich from bribes, buying their freedom, and eventually, some, their childrens'.

No one remarks how trite and formulaic the frescoes' compositions are. They are painted as if from soap-opera re-enactments performed by actors bored to tears. Evidently whoever commissioned the frescoes couldn't tell, cared less, or could do nothing about it. That who paid for them was Aulus Rustius Verus, a local politician, tracks. The mosaic floor of 3 million tiles with no more decoration than a double black line around the perimeter tracks, too; probably rugs covered most of it.

These are lavish trappings of a slave-keeping society. The slaves could be compelled to paint and lay mosaic tiles, but not to care. They were anyway able to ensure viewers would know. Moderns working in advertising will understand.

We know, anyway, that they used untold millions of cat mummies for locomotive fuel. In other news, Egyptians mummified millions of cats.
angiosperm··on If Inheritance is so bad, why does everyone use it?
Most of us have no contact with Java. But Java offers little else than inheritance to use to organize a system, so Java coders use it for everything. They are not exactly wrong, except in using Java at all. But sometimes is all that is allowed.

Are these the bacteria that literally all other life on earth depend on to split N2 so they will be able make protein and reproduce?
angiosperm··on The Great Oxygenation Event
99%+ of species were driven to extinction, first from their environments becoming bathed in oxygen they were powerless to resist, and then from the whole planet freezing over for an eon (except maybe some equatorial refugia). Volcanism eventually restored enough CO2, with the oxygenators frozen, so the ice could melt.

More to the point, geo-engineering is guaranteed to fail if emissions are unchecked. Whatever gains the former can offer, the latter may easily overwhelm. Our only hope is for emitting processes to become much more expensive than non-emitting alternatives. Fortunately we are on that path, although entrenched interests force emitting processes to continue well beyond economic rationality. E.g., new coal burning infrastructure being built even now.

With any luck, it will happen in just a few centuries as waste heat from industrial processes grows without bound, unless industrial expansion moves off-world before then.
angiosperm··on Terraform Industries converts electricity and air into synthetic natural gas
The social benefit of such production, considered strictly, probably far exceeds methane. But methane costs more to ship, and displaces demand for Russian gas. Economics is hard.
angiosperm··on Terraform Industries converts electricity and air into synthetic natural gas
Displacing mined methane is an overwhelmingly better use of excess power.
angiosperm··on Terraform Industries converts electricity and air into synthetic natural gas
The economics of this sort of thing is full of surprises.

Someone with a solar farm who cannot sell the excess they produce at noon (local utility won't take it) can put it into producing methane to sell (or use), if the equipment is cheap enough to amortize over only the over-productive intervals. And claim extra carbon credits for displacing mined methane. They might install some extra panels to increase the intervals. Displacing methane they would have had to buy yields more value.

Probably in the future it will be more profitable to produce ammonia instead. Ammonia is even more useful than methane.

angiosperm··on Terraform Industries converts electricity and air into synthetic natural gas
Methanol is strictly harder. There is enough demand for any amount of hydrogen or methane that can be produced cheaply enough. Methanol can wait until those are saturated. Ammonia might be another intermediate step before it is worth doing methanol.
angiosperm··on Debian on xz-utils: revert to version that does not contain changes by bad actor
Wow, thank you!

So it is wrong for such a fundamental service as systemd to depend on such complicated processes ... just as the anti-systemd people said. Except of course shellscripts and /bin programs are just as complicated, when you check.

> That can only be caused by overregulation.

That reads like a creedal statement. We see the same effect in all regulatory jurisdictions, indicating the effect is instead intrinsic. A more fundamental observation is that the more we learn about building nukes, the more expensive they get.

Best would be to disable anything in sshd that can perform compression or decompression. There is no value in that capability, and way too much risk.
