Every large building in the last 100 years has been built with multiple integral fire-safe paths of egress for the very reason that a path should be available if one is blocked. The design of buildings is very much conditioned on tables in the fire code about how many paths of egress, how large they must be, and how long they can be based on how many people need to be evacuated. (Not to mention how many hours of fire each door and partition must be designed to resist.) It's kind of a PITA. And it works very well.

External fire escapes are merely the retrofit allowed to old single-stairway buildings to get them to be vaguely as safe as a modern building.

It would in practice be (mostly) fine, just as it is elsewhere. But electrical safety principles in the US are typically "must be safe regardless of the dumbest possible use" so that "mostly" is a big obstacle.

Generators are typically grid-forming. They can (and will) be out of phase with the grid power, and will backfeed and create hazardous conditions upstream if the grid is out (and your main breaker is still on.) To use a generator safely you need a transfer switch (or similar) to make sure only one source of power can be active at a time.

Solar inverters (esp for this use, but also in general) are grid following; they'll use the existing frequency and support it, and if the grid goes off they'll go off too and do no power-off backfeeding.

The inverters are thus broadly safer to be plugged in to systems that are otherwise unprepared.

Generators could be made grid-following (many are now inverter-based), but for most users that would be silly, since the supplemental power would be more expensive (and louder!) than from the grid.

There's not much older than the Vasa that is essentially intact. The Vasa is in good enough shape to have been recovered as a ship, and not as a shipwreck or an archaeological dig, which is pretty remarkable. I think there's one Ottoman galley a bit older that's been continuously maintained, and that's about it.

> The Mycenaean palaces had developed a syllabic script, which we call Linear B, to represent their spoken Greek. This form of writing is entirely lost. In the 8th century, the Greeks will adopt an entirely new script – borrowing the one the Phoenicians are using – to represent their language

You've misread something. Linear B encoded Greek, but is not related to the Phoenician-based script.

Crew Dragon flew an automated demo flight before flying with crew. It was proceeded by 20 flights of Dragon 1 over 10 years.

Starship's heatshield has already been tested full-up half a dozen times. Many changes have been made as a result.

Belgian glasses, like wine glasses, leave room for head and aromatics.

Belgium is also fanatical about matching the glass with the beer, and Europe has the very sensible pour line on glasses, so it is designed for a certain fill and filled to the design.

It's designed for experience, not volume.

I don't see that Google cares much about backlinks any more. Seems like it's all about "content" keywords and maybe a little time-on-site. The domain is a huge signal, which is probably where the problem comes from here.

Sadly, Google's generally better against all the new AI-generated content farms than other players, so maybe they're still running PageRank somewhere.

Industrial buildings are typically built at dock height. Even if they don't do any grading, that would put the building well above any plausible flooding in that area.

There is a problem with the number of dimensions. Even a t-shirt is described best in neck, chest, waist, and you could add several parameters for sleeves and also for heights. Neither consumers nor manufacturers can really handle the combinatorial explosion, so you have to boil it down to one or maybe two dimensions.

But the reason even that isn't done is mostly history and market expectations. There are clothing categories that sell in actual dimensions, and (aside from the terrible dimensional accuracy of clothing in general) it works fine. But those are all on the "men's" side, and it seems the industry believes women will not like buying based on actual numbers.

"Plaster" can be lime, gypsum, or cement, in rough order of historical adoption. Sometimes you even use different types on the same wall; cement rough coat and lime or gypsum top coat, for example.

Because this is not about charity, but about politics. Specifically demonstration with the intention of advocacy. The advocacy falls down when the demonstration is less applicable.

The idea here is that the economics of launch are changing with Starship such that the "incredible cost" and "overspeccing" of space will become much less relevant. There's a world where, because the cost per kg is so low, a data center satellite's compute payload is just the same hardware you'd put in a terrestrial rack, and the satellite bus itself is mass-produced to not-particularly-challenging specs. And they don't have to last 30 years, just 4-ish, when the computer is ready for retirement anyway.

Will that come to be? I'm skeptical, especially within the next several years. Starship would have to perform perfectly, and a lot of other assumptions hold, to make this make sense. But that's the idea.

It's a mid-50s bomber. The skin will be easy to replace. Drill out the rivets, rivet on new sheet metal. I don't think it even dragged the wingtips.

Might be some complications with the nose gear and the payload bay (the main gear is on the wings, and untouched) but nothing terribly complicated. I wouldn't be at all surprised if it was designed with some assumption of belly landings; it's a warplane after all.

Repairs surely isn't automatic, and who knows how tight that's program's budget is, but planes are repaired from such landings all the time, and if they attach any value to the vehicle it can be repaired, and not at great cost.
