Usually it boils down to ablatives. Either your pusher is designed to ablate at a known rate and factored into the propulsion calculations as fuel mass, or you are protecting the pusher plate by doing something like injecting synthetic oil that wont spontaneously boil in the vacuum of space through pores in the pusher plate so that the oil becomes a protective layer that boils off instead of eroding the surface of the pusher plate.

The other method I've seen is to "go big" and scale things up to the point where the pusher plate is collecting enough force, but spread over a sufficient area that while the pusher can effectively and "safely" capture the plasma debris from the pulses while keeping the flux of high energy photons low enough that it doesn't erode the pusher plate from the radiation flux. The "Medusa" design scales this up to the extreme, putting the explosion ahead of the spacecraft and using a giant spherical "sail" to capture the energy from each explosion, if you simplify Project Orion as "explosion under pogo stick while you stand on it", then the Medusa design is "explosion above your head while you wear a hard hat, holding onto an umbrella with a pole made from elastic bands".

Since you mention the tests with conventional explosives, I love bringing up the actual tests that were done when people talk dismiss Orion as an impractical idea that wouldn't have worked, seeing the "Hot Rod" fly powered by RDX explosions is usually enough to convince someone the physics of the idea is completely sound.

> Instead you build and live in highrise/towers

I mean, I'm sure this is valid in some places but having lived in high rises relatively far north in Canada let me tell you it is very possible (and in my experience very common) to build high rises that retain heat so well they basically bake the occupants in high heat/humidity.

I doubt most of North America's high rise apartment buildings above some latitude are particularly well equipped for this, so there's almost certainly a shift required in how you build them.
I am one hundred percent certain that both the locatelli grocer that has almost nothing I want to eat in it ever and has nothing but mexican standoff intersections with people walking around really slow, and the 'california' grocery that I really have to work hard at not just eating all the food in inside the store are both heavily planned, in terms of where exactly they are and all of the ridiculously excessive lighting and product placement inside of the stores. There is some vague pretension to a capital market and some vague notion that some of the great many retail businesses which are essentialy a second form of rent extraction may go out of business, but by and large it would seem extremely clear that there is a great deal of planning going on with information that business people are not supposed to have access to. Whether or not there is a viable alternative to said situation is a more complicated question, but there is no question that there is not some kind of innovation() support system where if you just figure out how to build a better mousetrap or run a better grocery store or sandwich shop, you will succeed and grow.

> We have only 50 million years before Earth's ability to adapt to solar warming pegs and the temperature starts crawling up

This sounds like an oddly small estimate. Life has been around 3.5 billions of years and has passed through multiple extinction events. It would be a puzzling coincidence that human civilization appears and then we have only some tens of million years to avert catastrophe.
>Is that true even if it has a large mass from cargo?

Nope. It's just plain false.

To wit:

During its career, Graf Zeppelin had flown almost 1.7 million km (1,053,391 miles), the first aircraft to fly over a million miles. It made 144 oceanic crossings (143 across the Atlantic, and one of the Pacific), carried 13,110 passengers and 106,700 kg (235,300 lb) of mail and freight. It flew for 17,177 hours (717 days, or nearly two years), without injuring a passenger or crewman.

It never crashed, and was retired at the dawn of WWII.

The huge airships get a bad rep because the only country which could successfully build and operate them was Nazi Germany.

As for dirigibles operated by the US, the UK, and the USSR... yup, none of them actually worked.

It didn't mess up the instruction "make every fifth line bold". The blank spaces between each "paragraph" are empty lines, so it counted them too. I think this is perfectly reasonable behavior, it's what I would have done absent further instructions too.

You can see it in the generated code on the bottom right during that part of the demo. It loops over the lines and bolds them when index % 5 == 0.

Edit: I guess with the 1-based indexing of natural languages, the code actually bolds lines number 1, 6, etc. So arguably it should have done index % 5 == 4 instead, to bold lines number 5, 10, etc. But funnily enough, if it had done that, it would have bolded all the empty lines, so it would have seemed like it didn't do anything.

Walkable yes, but often not safely bikeable, which unfortunately limits mobility options quite a bit. I live in Philadelphia and likewise have lots of options within walkable distances/a subway station nearby - that's a big part of why I live here. But here we only have two subway lines, going roughly north/south and east/west. If you need to get anywhere that's not well served by those, your main options are:

- Take a bus, most of which only come every 15 minutes at most

- Walk, which is doable bit adds another 20-30ish minutes to your trip depending on exactly where you're going

That would be more like 10 minutes max on a bike, which easily makes it one of the fastest ways to get around if you consider that you'll be spending several minutes just looking for parking if you were to drive. But the city still prioritizes cars above all else, making it not really a safe option. I absolutely would bike everywhere here if I felt safe enough to do so.
No they can't. You're just to inexperienced to know this.
There's a far larger area of the world which is too cold & dry for human tolerance, yet people survive & thrive there. Probably the same for places which are hot & humid.

There are some tax and work permit/visa consequences so it's not as simple. E.g. someone who can not legally work in the US may have a problem presenting a US bank account and an SF mailbox. The requirements may vary in different countries/states.

But I agree we may be headed towards a future where pay is no longer a function of location. If you can't tell where an employee is physically it's a lot more difficult to have location based payments. A remote employee can be anywhere. When I worked remotely (way before the pandemic) I spent some time working from Hawaii and my employer did not even know.

DECLARATION OF INDEPENDENCE
If all men are created equal, that is final. If they are endowed with inalienable rights, that is final. If governments derive their just power from the consent of the governed, that is final. No advance, no progress can be made beyond these propositions. If anyone wishes to deny their truth and their soundness, the only direction in which he can proceed historically is not forward, but backward toward the time when there was no equality, no rights of the individual, no rule of the people. Those who wish to proceed in that direction cannot lay claim to progress. They are reactionary.

I mean, the AST doesn't help at all with comments which are potentially the most valuable part of the code to an AI like this. Formatting is also ignored by the AST but may play a role in understanding, just as it can for humans.

The model can clearly already generate large amounts of code with no syntax errors in one shot. It's probably better at that than I am, I always need to fix something after typing a bunch of code without calling the compiler. I think that instead of adding a bunch of language-specific AST stuff it would be far better to simply give the model the ability to iterate on its solution the way humans do, to fix any syntax errors or logic bugs discovered by the compiler or at runtime. That could potentially work in a generic way for any language. It seems like the obvious next step, though figuring out how to train it is not obvious.
A lot of new technology could potentially solve this problem.

Yes, that's true... but often, visible symbols don't have enough information to get deduplicated anyway. Often, the symbol is just an address within a section in the object file. The section contains other code, and you can't remove things from it... by default, on most systems.

E.g. if you have file.o, the linker will see something like this:

section .text: [...16kb of data follows...]
section .data: [...2kb of data follows...]

my_function = .text + 0x1f3a

This is simplified, but it just illustrates the core of what an object file looks like during linking.

It's just not enough information to go on, if you want to deduplicate a function. C runs on weird embedded systems. You might think, "Just use LTO" and well, those weird systems don't always have LTO. You might think, "If you care about code size, don't use inline functions!" and well, sometimes, inlining a function results in smaller code!
This goes for humans too. Ultimately, "something similar was in the training set" is semantically indistinguishable from "having a rich generalizable conceptual toolbox".
I did foster care briefly. Children were in my care after mom was charged with a crime and in jail awaiting trial.

One of the kids needed a medical authorization approved by the parent so I naively waltz into the local jail and say, "I have a piece of paper for so-and-so to review and sign"

Oh boy, they laughed and laughed at me. You idiot, only lawyers can do that. And her lawyer for her criminal case isn't going to be here for awhile. They said we could talk to her for like $10/min on a video conference system (she still couldn't sign anything) I was like, yeah but I am here face to face, they laughed again. That isn't safe. Only lawyers can talk face to face, you must talk through a video chat system located on site for a nominal fee.

Screw this. So we played the song and dance that involves shuffling papers to court appointed lawyers, waiting several weeks, and this latency made every tiny insignificant element of us providing the best care to these children absolutely impossible.

We quit foster care after 3 months.

Gnome is in fact great, and has great usability. But my point was, for many Linux users (perhaps the most vocal), care about GUI looks over GUI usability. So GNUStep/WindowMaker are simply too "ugly" (although I think the experience of using them is superior to Gnome).
Similar question to this that I've been wondering this wildfire season -- at what point is AQI (Air Quality Index) too severe for human tolerance? The scale tops out at 500, what happens to a person if the air is even worse than that?

Some sensors near Medford, OR are reading in the upper 400's and even low 500's -- what happens if it hits what would be the 1000's if the scale went that high?

I'm mostly thinking of particulates, but AQI includes other gases like CO, SO2, NO2 so maybe those would be more dangerous than particulates (and certainly harder to filter out)

>Never has there been a law that says you cannot evict somebody after 18 months of not paying rent.

I used to work in mortgage default - and yes some foreclosures. There are some really weird state laws that extend eviction protections.

In New York City, if a renter has an agreement with the person with the mortgage - the bank can foreclose on the house, but we must honor the rent agreement. We had someone rent their house to their mom for $500/month, we "got the house", but the mom got to stay as long as she paid us $500/month in rent

In Massachusetts (iirc), after filing the "first notice of default", banks need to wait well over a year before finalizing the foreclosure.

Foreclosures are ultimately handled at the county court house - and the county makes the rules. They county tells the bank "fill out this paperwork". After the 2008 recession, some counties would change the COLOR of the form and then tell banks "sorry, wrong form, start over" and let the tenants stay in their house.

I'm not opposed to any of these situations, I'm merely mentioning them because local governments can and DO place long protections for tenants.

Gosh I would love places like this in the Bay Area.

I recently watched a video [1] about the planned cities built by the Soviets and it all seems really nice. One advantage in their case is that they planned industrial activity as well so they built residences within bicycling distance from factories (with green space in between) so people could get to home, shops, and work with a walk or bike ride.

Actually I remember that Japan has done a lot of industrial planning too, but I don’t know if they paired that with residential and commercial spaces. Something to look in to. (Please comment if you know.)
