Sure, it's obviously a matter of diminishing returns and opportunity cost. But the re-engine for the A380 was basically a rote, low-risk, B-team exercise for Rolls Royce. All they had to do was tweak their existing generation stuff. The program was already well underway, and they still dropped it; they all but explicitly said the reason was, "meh, we lost interest". Something seems to have changed.

Putting my cynical cap on, my hot take is this: Everybody now realizes that Emirates and Clark are exactly right. As was Airbus.[1] Demand will blow past supply (i.e. runways and gates). Ticket prices will sky rocket. But from the perspective of the plane and engine manufacturers this translates to, "if everybody sits on their hands and does nothing, we're going to enjoy a windfall of profits". Clearly, IMO, Boeing, all the engine manufacturers, and now (somewhat despite themselves) Airbus, are going to passively collude[2] to bring about this windfall. All they need to do is sit tight and wait things out. The threat of competition isn't significant enough to break the collusion; there are too few players, the barriers to entry--regulation, technical and logistical expertise, etc--too steep, and like with housing little prospect that political reforms will make it easier to build enough new runways and airports to change the capacity trajectory.

Similar calculus applies to most of the established carriers. There's much more competition among them, but if the manufacturers are expected to continue to coast there's no angle to exploit in that regard and thus little incentive to agitate for disruption along this dimension, and so the carriers also get to look forward to windfall profits, notwithstanding that they'll be forking over much of it to the manufacturers. Clark just isn't cold-blooded enough to want to play that game; he's got too much of a fighting spirit. (Or perhaps more realistically it's also because if Emirates doesn't keep growing it won't be viable in this prospective future reality?)

[1] Boeing wasn't wrong, either, but point-to-point only bought a couple of decades of supply expansion.

[2] I think there's an economics term for this, but I don't remember it.
Useful keyboard shortcuts I learned too late
I'm pretty YIMBY, but I don't really have an issue with popularly mandated style guides for development. As long as they are A) set in advance, not in response to individual development plans and B) aren't deliberately prohibitive of varying types of development. If an area wants to, say, mandate that all buildings are Art Deco, that'd be pretty cool to live in and visit. An area that wants to ban anything but single family homes should go rot.
It's pretty hilarious, surely nobody will take either the FBI or ICE seriously?

One is a law enforcement agency, the other is a migrant rights abusing agency so there is a severe conflict of interest...

Also, officers of old did a lot more with a lot less, so they should just do their jobs instead of relying on easy access to communications, or simply put: be less incompetent.
Democracy in microscopy: cheap light microscope delivers super-resolution images
I mean, I spend a lot of time discussing this stuff with actual local development opponents, so arguments like these in the abstract just aren't that aggravating. I'm often happy for people to mount the most superficial arguments against things I believe in; might as well lay the flimsiness of the opposition out clearly.
I don’t think 25 fonts has ever made something better. I’m sure there is a number greater than 1 but less than 25 where we can read happily.
> More importantly, satellite positioning receivers need a cached "ephemeris" file that helps them predict which satellites will be overhead at a given time to operate efficiently, accurately, and quickly.

Interesting, I've never heard of that particular optimization for GNSS before. I know GPS transmits ephemeris information in each frame, since that's the input data for the positioning calculations. I've got a number of Garmin watches, and they've always been able to get a position fix even after being disconnected for weeks.

I find GNSS implementations very interesting, which manufacturer is making their watches like this?

What your essentially saying is "alignment is very hard", which is what those researching alignment say. And they often use the example of how inter-human alignment is hard as evidence for why it is a hard problem. But saying it is hard is not an argument for why it is essential or not.

While humans are not perfectly aligned, especially if you just look at individuals, we are collectively aligned enough that many people can live together in communities of various scales. That imperfect alignment has been good enough that we have scaled from small tribal groups to an international network of nations. We need AI alignment to be good enough if we hope to continue advancing.
Thanks for sharing these. I wasn't expecting an Air NZ plane when I clicked on the links – my father (a pilot) flew that exact plane when he was rated on the 777 over 15-years ago.
Not well. Feel free to prove me wrong. Doing more localized measurement of your hands or your tongue will give you much more accurate readings of what it's actually doing and you can build a proper control scheme.

Why not put relay satellites that orbit the moon?

Actually I think this is already being planned anyway, unrelated to a telescope.

(on the unstable lunar orbits...) https://en.wikipedia.org/wiki/Lunar_orbit

> Gravitational anomalies slightly distorting the orbits of some Lunar Orbiters led to the discovery of mass concentrations (dubbed mascons) beneath the lunar surface caused by large impacting bodies at some remote time in the past. These anomalies are of sufficient magnitude to cause a lunar orbit to change significantly over the course of several days. They can cause a plumb bob to hang about a third of a degree off vertical, pointing toward the mascon, and increase the force of gravity by one-half percent.

> ...

> Study of the mascons' effect on lunar spacecraft led to the discovery in 2001 of "frozen orbits" occurring at four orbital inclinations: 27°, 50°, 76°, and 86°, in which a spacecraft can stay in a low orbit indefinitely.

Consider that - there are only four inclinations where you an orbit the moon without needing to do constant adjustments. Whereas with the Earth basically all the inclinations are available.

And unscramble an egg, and reverse flow of entropy too.

The problem of AI alignment is that human value system is rather complex (to the point we haven't formalized any meaningful chunk of it, nor it seems we'll be able to any time soon), and random deviations from it can easily lead to - what we'd consider - horrifying tragedies. A random AI mind plucked out of space of possible minds is highly unlikely to have internalized a good approximation of our value system, for the same reason putting a scrambled egg in a bag and shaking it vigorously won't get you a fresh egg back.

Manipulation and exploitation are, by default, what happens when an agent with power over you finds you standing between it and the thing it wants. Almost every point in the space of possible minds will feature this behavior. "Love, understand, help each other", in the sense we understand it, is a very specialized, specific set of behaviors - few points in the space of possible minds will feature it.

Or, in short, there's a good statistical argument (to which I do not do justice here), that if you make a smart enough AI without doing a perfect job alignment, it will kill us all - most likely unintentionally.
I'm not certain that this is exactly what you're talking about, but one of my dictionaries (Webster's New International, 1916) includes this under the entry for Authentic, which brings me great joy:

Authentic, Genuine. The prevailing sense of authentic is authoritative, trustworthy, with the implication of accordance with fact; as "confirmed both by legend and authentic record" (Froude); "assurances more or less authentic" (Wordsworth); an authentic portrait. The prevailing sense of Genuine is native, real, true (see Real), often with the implication of descent from, or correspondence to, an original source or stock; as, a genuine merino, genuine piety; "true simplicity and genuine pathos" (Wordsworth); cf (colloq.) "the genuine article" with "the real thing." Both terms are used - genuine more frequently than authentic - as opposed to spurious, counterfeit, apocryphal; as "Let them contrast their own fantastical personages ... with the authentic rustics of Burns" (Jeffrey); "What is genuine knowledge and what is its counterfeit" (J.H. Newman). The 18th century distinction between the two terms, as applied to documents - "A genuine book is that which was written by the person whose name it bears as the author of it; an authentic book is that which relates matters of fact as they really happened" (Bp. Watson) - while still often observed, is becoming obliterated in present usage; as "The criticism which thus so freely diminishes the numer of his [Giorgione's] authentic works" (W. Pater); "Some collectors frankly take the ground that they buy what pleases them, and that age and authenticity are minor considerations" (The Nation). See Real, Correct.
I use a python library called python_dotenv, which like the article describes, loads environment variables from a .env file. My use cases are for just tiny personal projects, but, I do like how the process is the same on my laptop and my web host. If i were to use some specific technology with digital ocean, I would still need to do something for when I'm building this stuff locally.

Generally speaking the only thing I'm holding in my .env file is the Django secret key, and the debug flag, so, pretty limited use case, but works well I think. I manually create the .env file when setting up my site, so none of it goes into any repos.

A fair part of Russian economic 'growth' is in military supplies. When you are attacking another country and looking at almost no gains in the end this is a disaster of epic levels. If you have a gain in the end you can justify the expense in the revenue from the spoils you captured.

At it's current rate Russia is looking like it will get none of that. It will not gain any new territory. It will lose massive amounts of equipment and personnel directly. It has lost massive numbers of better off people that left the country. This is a demographic and economic nightmare, that keeps getting worse when you look at the preconditions.

Before the war Russia was making huge amounts selling natural resources, but was already running into problems funding its retirement (something Putin said he'd never touch when he was first elected). Well in the past few years Putin did have to raise the retirement age and tried to reduce the retirement benefits which was causing massive problems internally. Now that problem is even worse and puts Russia at risk of complete internal collapse.
Yes. It's a text-led book, so set your expectations accordingly, but there are plenty of black and white pictures (mostly screenshots) throughout. There's also a colour plate section in the middle with a bunch of photos (a mix of people, floppy disks, and game boxes).

If you mean the NURBS code, there are no plans to separate it for now. It does live almost entirely in the src/surf folder and does not depend on the sketch entities or constraint solver.

My hope is to squash the remaining bugs in that code. I'm currently working on an issue with coincident and tangent surfaces.

The constraint solver is available as a library and is currently used in FreeCAD assembly 3 workbench, as well as the Blender CAD Sketcher addon.

> 1. Show that the problem of child abuse on social networks is wildly out of control. I hear about it all the time, but what are the numbers? Where is the data?

The same people that say it's rampant on social media are the same people that also still say the majority know their abuser (ie family members etc) - it's all narrative, no substance.

Also if it was as widespread as they claim, the statistical probability would mean that almost everyone knows one or more victims, that isn't the case either...
Great game, controls felt tight and difficult was well balanced. My one complaint is the stages are way too long, it feels like a slog until you get to a boss
Both these options don't feel good to me. Hard to really tell what is ultimately worse, when I can imagine similar outcomes when irresponsible or malicious agents have access to sufficiently powerful AI.

Main positive point for open models is that we will start seeing the abuse sooner and at smaller scales. That might give us more time to build an immune system up against exploits by encouraging us to prioritize development of comprehensive AI safety practices.
> For the 10+ crowd, the days of kids roaming the streets, finding their friends and playing are gone. I think the causes for this are complicated, and social media (and screens) are just one part of the puzzle.

Blood hell. Kids will be like zoo exhibits of the last of their species. Seems in everyone's benefit that they are well-socialized, street smart, well-educated, AND not make virtually the same mistakes everyone else are making. We can rapidly go from the myth of "overpopulation" to population crash in as short as a generation.

Edit: Since this is getting downvoted I'll be more explicit: The human brain may well be also just described as some simple sort of thing, but that doesn't mean humans are not dangerous, nor hypothetical humans with a brain ten times as large and a million times faster. The worry about AIs killing all humans soon is not naive just by sounding naive.
This is a pretty ignorant comment.

Whaaa? Russia is sending T-55s to their front to deal with massive material losses. The losses are closer to the numbers we'd expect in WWII, not a local border war where they are the attacker.

You are watching Putin fight to keep alive (note, not keep Russia alive) at this point. Bakmut will go down in history has Putin's mad king moment.

Anyone else think its an abuse of terminology to refer to speaker conditioning as "in-context learning" and "prompting" now?

Like, using a reference encoder to condition on an unseen target speaker has been around for 4 or 5 years now. These results are already cool without mystifying the results by calling this "prompting" or "icl"

Unless there is some subtle difference that warrants the new terminology?
That's what pruning is, but it's not that straight forward and has limits. Finetuning a smaller model on the output of a larger one is much more flexible and reliable.

GPT 3.5 is probably a 13B Curie finetuned on the output of full size GPT-3 175B, to give you an idea of the technique.

That is smaller than the third smallest StableLM and the same size as LLaMA-13B which can run at useful speeds off of a smart phone CPU.

There's just no way this'll get past the lawyers.

I agree, it's a great way to assess students. I've been through them too, they are nerve wracking, but end up being a lot better than written.

But the lawyers, man, they'd hate it.

There's too much variability. Some students would get 'harder' questions than others. Some would get 'grilled' more in depth. Some would be asked to turn around and face a whiteboard more. Some students would say this is because I'm part of a certain category. And of those students, a lot would unfortunately be in the right. Because professors are just as biased as the rest of us, if not more so.

So, if you'd want to do this, the lawyers would say you'd need to have at least one person of every imaginable category in the room giving questions. And it would need to be an open exam (Pence rule), and they'd like for the exam to be recorded too, video and audio. And you've got to use a rubric with standard questions, so we can make sure there's no bias. Which means you have to sequester those that completed from those that haven't, phones included. And the proctors have to be behind a screen. And a few dozen waivers, just to round things off.

As others here have said, the expense would be huge. At least a handful of people, A/V techs, a revolving door of students, translators, the works. All just to end up asking students the exact same questions anyway.
>The traditional problem with nasal vaccines is that they induce a quick spike in antibodies in the mucosa, which then go away without the corresponding long-term rise in cellular immunity that is seen with injected vaccines.

Are you talking about traditional vaccines or mrna ones for covid? Because aside from mucosa it sounds like you're describing the short term durability of mrna vaccines that need to be perpetually redosed months not years later. If that's the baseline, what is there to lose by adding or replacing them with short term mucosal immunity?
"It is refreshing to hear opinions I already agree with. People with other opinions are unintelligent"

You're missing the fact that I'm also growing said trees. If I plant a bunch of trees to sell the lumber as firewood, I turn around and plant more trees so I can sell more wood in the future. Those trees capture the C02 released by the first batch, and then I sell them again. This is especially true with algae ponds, because 1) there's no chance there was an existing algae pond that would put me 1 batch in the hole on carbon neutrality and 2) it takes a lot less energy to grow and harvest.

In contrast, digging up coal has no carbon recapture stage. I dig up coal, it gets burned, releasing C02, I dig up more coal.

No one's saying biofuel is carbon negative. But it's pretty close to carbon neutral.

I don't know if it's particularly inspired or "grand idea" - it's just a 2d multiplayer rpg, and with something like that the sky is pretty much the limit.

If I had to peg my general philosophy, which is tied to how I like to play games: it's on being open minded when it comes to strategies players can use to overcome challenges within the game, and try to codify some of that within the systems built into the game so players have options to overcome challenges in ways other than gladiatorial-like combat.

Basically, I think "exploiting" is fun, and believe it's an overused term.
