2) Police officer hides, catches unsuspecting driver speeding, stops driver, issues summons.

This is the very best approach. It's got the perfect tension leading to the greatest safety.

When you're expecting such an ambush (getting caught a few times will teach you to do that), and you're really paying attention and playing "spot the ambush" then they won't catch you. But because you're being so damned focused and alert, you're also a safer driver.

OTOH if they nail you, that means you weren't paying attention. So you weren't merely speeding; you really literally were speeding unsafely, and the ticket is the proof. (If you were so safe, then how come you didn't see the guy with the radar gun in time?)

Every. Single. Time. I got ticketed, my mind was wandering and not fully focused on the road. I wasn't looking for a speed trap, so I didn't see it in time. Busted. And those times I was looking? I didn't fall for it. I slowed down and avoided a ticket.

The ideal system (in terms of safety) happens to also be downright sporting! The ol' classic speed trap was almost .. a game?

That's generally how it's being done. The robot reads the code and writes specs. Then another robot reads the specs and writes code. If courts still accept the traditional clean room defense (and why wouldn't they?) then they're probably going to say it isn't a derived work.

It looks like the big catch, the actual source of uncertainty, is that the instance of the robot that reads the specs and writes code, may have seen the original code as part of its training data. That'll be enough to keep it from being a true clean room. In those cases, you'll be totally right.

But for any particular given project, was it trained on the original code? That'll be a case-by-case thing, and I think in a very long-term way, the answer will increasingly be No, simply because codebots' need to keep training on newly-published code, will diminish.

As an analogy, imagine you're a human author, and for some weird reason, one thing you like to do is have people tell you high-level plot summaries (specs) and then you write a detailed story from that. Someone says "the moon is unusually bright one night and people fear something bad has happened" and you write a story much like Larry Niven's Inconstant Moon, from that prompt alone. And you do this with 100 more stories, and most of them honestly don't appear to be derived. You take specs like "bombardier has crazy war experiences" and your resulting story is nothing like Catch-22.

But then one day, you're up in the attic and you find an old box that's been sitting there for decades, and inside, you find an old, worn, dog-eared paperback of Larry Niven stories which happens to include Inconstant Moon. Oh shit, you must have read that 45 years ago and then somehow "forgot" that you had, so your story wasn't truly independent of Niven's work. Your story turned out to not be "clean" at all, whoops! It was a derived work after all, because you read it ("trained on it") when you were a kid.

But the other 100 stories? Nope, those really were clean. Your story-writing process was almost legally foolproof, except that you had to learn reading and writing at some point, so your childhood favorites needed to be off-limits.

The heat wave made March be like late spring. Things that normally bloom in May, bloomed in March. And yesterday I got my first MRGCD irrigation of the year, flooding my back yard and letting the shade trees greedily suck up the water. We're spending a lot more time outside on the patio, compared to previous years during this time-of-year.

If I were stupid, I would be out of my mind with pleasure. Things feel wonderful right now.

But that water I just got .. that is The snowpack, probably. Instead of getting it all throughout summer, this first irrigation is probably the last, or second-to-last.

This summer is going to SUCK.

If a computer program ingests code (whether GPL or not) and then outputs some code, the big question is whether or not the resulting code is a derived work.

If it's not a derived work, then the license of the original code is irrelevant, and it doesn't matter if it's GPLed, fully proprietary, or somewhere in between. The license has no say in the matter, because nobody ever needs to agree to the license; whatever they're doing is legal under copyright law so they already had all the permission they needed, without ever needing the additional rights granted by a license.

If it is a derived work, then that's copyright infringement unless the person who does it has permission. And the only way to get permission (i.e. cause copyright infringement to have not happened) is to agree to the license. So yes, the output would have to be GPLed.

But I don't think we really know whether or not robots reading code and then writing code from what they "learned," are creating derived works. Ask again in a few years, after a few court cases. This is hard. Rational people can disagree and come up with pretty good arguments no matter what side they're on. We'll see what the courts decide.

I think the most interesting case for determining it, won't involve a GPLed input. It'll be if Anthropic sues this project, since they will have contributed arguments to both sides. They'll have to argue "it is a derived work" in court, but to all their customers, they have and will continue to preach "it's not a derived work."

You're confusing the importance of avoiding Kessler syndrome in LEO with the difficulty of causing Kessler syndrome. GEO debris can potentially remain there for millions of years before interactions between the gravitational pull of the Sun, Earth, and Moon sufficiently perturb it. LEO debris remains for weeks to months. You have to have many orders of magnitude more debris in LEO to trigger Kessler Syndrome, where the rate of collisions exceeds the rate of debris loss.

The fact that a LEO Kessler Syndrome would also be short is something that exists on top of that.

It's also worth nothing that not only are modern satellites not only vastly better at properly disposing of themselves than they were in the 1970s when Kessler Syndrome was proposed, but they're also vastly better at avoiding debris strikes. All of these factors are multiplicative together.

People forget that the primary concerns about Kessler Syndrome were about geosynchronous orbit, which used to be where all the most important satellites went (many of course still go there, but not the megaconstellations). It takes a long, long time for debris to leave GEO. But LEO is a very different beast.

Yeah. In particular:

with fragments likely to fall to Earth over the next few weeks

LEO FTW. Kessler Syndrome is primarily a risk if you put too much stuff with too poor of an end-of-life disposal rate in GEO. End-of-life without proper disposal rates have declined exponentially since Kessler Syndrome was first proposed (manufacturers both understand the importance more, and do a better job, of decreasing the rate of failures before deorbit - in the past, sometimes there wasn't even attempts to dispose of a craft at end-of-life). And now we're increasingly putting stuff in LEO, where debris falls out of orbit relatively quickly. It's not impossible in LEO, esp. with higher LEO orbits - but it's much more difficult.

Or to put it another way: fragments can't build up to hit other things if they're gone after just a couple weeks.

And this trend is likely to continue - a lower percentage of premature failures, and decreasing altitudes / reentry times. Concerning ever-decreasing altitudes, we've already been doing this via use of ion engines to provide more reboost (with mission lifespans designed for only several years before running out of propellant, instead of decades like the giant GEO ones), but there's an increasing interest in "sky skimming" satellites that function in a way somewhat reminiscent of a ramjet - instead of krypton or xenon as the propellant for an ion engine, the sparse atmospheric air itself is the propellant, so the craft can in effect fly indefinitely until it fails, wherein it quite rapidly enters the denser atmosphere and burns up.

The point of buying Trumpcoin is to pay a bribe. You just need to remember to communicate what you want in exchange for the purchase, out of band.

It's a really good system, but making it tax-deferred would make it even better. Since the goal is for Trump to end up with all the value, a Trumpcoin's value should be 0 by the time you're required to take distributions. That way, there's effectively no tax on your bribe. Win/win for everyone.

Relativity = gravity is represented by the curvature of spacetime. Curvature is linear, R. The formula treats curvature linearly. As things get closer and curvature spikes, the math just scales at a 1:1 rate

Quadratic gravity = Squares the curvature. Doesn't really change things much when everything is far apart, but heavily changes things when everything is close together.

Pros: prevents infinities and other problems when trying to reconcile quantum theory with relativity ("makes the theory renormalizable"). E.g. you don't want to calculate "if I add up the probabilities of all of these possible routes to some specific event, what are the odds that it happens?" -> "Infinity percent odds". That's... a problem. Renormalization is a trick for electromagnetism that prevents this by letting the infinities cancel out. But it doesn't work with linear curvature - gravitons carry energy, which creates gravity, which carries more energy... it explodes, and renormalization attempts just create new infinities. But it does work with quadratic curvature - it weakens high-energy interactions and allows for convergence.

Cons: Creates "ghosts" (particles with negative energies or negative probabilities, which create their own problems). There's various proposed solutions, but none that's really a "eureka!" moment. Generally along the lines of "they exist but are purely virtual and don't interact", "they exist but they're so massive that they decay before they can interact with the universe", "they don't exist, we're just using the math out of bounds and need a different representation of the same", "If we don't stop at R^2 but also add in R^3, R^4, ... on to infinity, then they go away". Etc.

The theory isn't new, BTW. The idea is from 1918 (just a few years after Einstein's theory of General Relativity was published), and the work that led to the "Pros" above is from 1977.
