The Remote Pop-In (2021)
It seriously freaks me out that Apple and Amazon are making movies. The tech giants really shouldn't be in charge of popular culture and the arts.

Amazon paid to lock down Lord of the Rings and very nearly to James Bond. Apple did the same to Foundation. Next is football.

You need an Apple device to watch Apple TV+, and their website is buggy as hell on other operating systems and Android.

I really don't like where things are headed.
Gioia's point about the worship of tragic, and sometimes even pathetic figures in modern fiction is right on the mark. He brings up Walter White as one example, but what I immediately had to think of when he talked about Marvel characters was Watchmen, Alan Moore's satire of that culture. What was so striking about the movie version in particular was how many people thought Rorschach was some kind of badass anti-hero, rather than the mentally ill Randian megalomaniac that he intended him to be. People didn't even get it any more, quoting an interview he gave on the topic: (https://www.stevensurman.com/rorschach-from-alan-moores-watc...)

"So, I thought, ‘Alright, if there was a Batman in the real world, he probably would be a bit mental.’ He wouldn’t have time for a girlfriend, friends, a social life, because he’d just be driven by getting revenge against criminals… dressed up as a bat for some reason. He probably wouldn’t be very careful about his personal hygiene. He’d probably smell. He’d probably eat baked beans out of a tin. He probably wouldn’t talk to many people. His voice probably would have become weird with misuse, his phraseology would be strange. “I wanted to kind of make this like, ‘Yeah, this is what Batman would be in the real world.’ But I had forgotten that actually to a lot of comic fans that smelling, not having a girlfriend—these are actually kind of heroic. So actually, sort of, Rorschach became the most popular character in Watchmen. I meant him to be a bad example, but I have people come up to me in the street saying, ‘I am Rorschach! That is my story!’ And I’ll be thinking, ‘Yeah, great, can you just keep away from me and never come anywhere near me again for as long as I live?’”"

when I read this I noticed how much this actually sounds like WW and how unironically celebrated the character was, in contrast to his family in particular online.

After running a few customer interviews with my personal network of NFT traders/investors, I have discovered interesting problems that they experience as traders/investors, which I experience myself and you probably do too without even knowing.

PROBLEMS I DISCOVERED:
- too many rug pools
- inefficiency
- too complicated
- all over the place

After that i discovered a secret, YOU don't actually need expertise to invest in NFTs. It's simple.

We are experimenting with a new concept that uses artificial intelligence to find promising NFTs on autopilot without effort on your part.

I would appreciate feedback about our landing page, comment down below.

If you experience this problem yourself or know anyone else, please don't hesitate to email me at mustafa.techleader@gmail.com or sign up to join the community now.

We are now moving quickly on this journey and eating all the feedback we can get and iterating. I love it.

I’m guessing a lot of the people in here bashing this attitude towards work are employed in tech jobs with good salaries, high levels of autonomy, and company stock options.

> Will everyone really always have what they need, or is that a theoretical state that is actually very unlikely to be achieved?

Just like our current system, there is no guarantee that everyone will have all their needs met. What differs, though, is what happens when those needs aren't met. On one side all you can do is complain and hope, on the other you get to raise the point to the community and you share the power to solve the problem.

> What happens if more than just one farmer opts out of the anarchistic lifestyle, they embrace capitalism, and outcompete the anarchists?

An anarchist society will produce enough for everybody. You can't outcompete what is already available for free through the community.

> Could that ever reach a point where it would be necessary to stop them by force in order to preserve the anarchistic society?

If that's what the society decides, then yes. It's all about the community decides for themselves.

> and not themselves in particular (which I think is more realistic, on average).

That's actually not true, the myth of the individualistic human, sold with stories of the proud family man who is the only one on earth who's able to save their progeniture, is largely wrong.
Perhaps time will prove you right, though (in the nicest possible way!) I hope you’re wrong.

Personally, I’m optimistic that we can do much better than 2x on the important metrics as mainstream programming languages and the programmers using them adopt ideas that already exist in more obscure languages, programming research, and development teams that don’t necessarily publish their experiences openly.

I think some of the potential gains come just from making it easier and therefore quicker to read and write our own code. Better syntax, more expressive language features, a more comprehensive standard library, and eliminating some of the historical baggage like how null/undefined are handled could all help a lot compared to today’s TypeScript, IMHO.

There are also other areas, such as safety and making it easier to work with other code from within or outside our own organisations, where today a huge proportion of a typical TypeScript developer’s time is probably wasted on things like wrangling dependency trees that could be much smaller and better managed, investigating preventable defects that currently reach later stages in the development process before they are noticed, and writing unit tests for negative cases that would be unnecessary if the language itself designed out those possibilities.

Something that struck me a little while back is just how unimaginably large this part of the programming industry has become. We’re talking about millions of developers working on web applications and companies collectively worth trillions of dollars. How much would even a 10% long-term improvement in developer productivity be worth to the world? What about 200%? What about 1000% or more? Personally, I think we still have a long way to go before we run into any inherent limits on developer productivity, and we’re learning more all the time.

Mars is ‘irrelevant to us’ if Earth is doomed, says Kim Stanley Robertson
Thanks for the interpretation, very compelling if that's what they're showing. Sci-hub doesn't seem to have this paper so I haven't been able to read the whole thing. But from what I can see the data doesn't seem to agree with what you're saying -

> The interesting part is this: If the vertically-oriented motors are made to move up-down on linear straight paths instead of curved paths, the net movement of the arm is not observed

In the video, it looks like the same kind of net movement is observed with the cylindrical configuration as with the spherical configuration. With the cylindrical configuration the average position migrates by about 0.2rad and stays there, compared with 0.3rad for the spherical configuration. So the spherical configuration seems "better"(?) but it's hardly a convincing difference given how much slop there seems to be - there's even significant net rotation in the "plateau regime" where it's apparently supposed to stop migrating.

And why is there a "plateau regime" anyway? If they can pull off a delta-V with no momentum transfer, I'd expect the robot to keep migrating around in a circle. But it stops. The abstract says:

> While this simple geometric effect predominates over short time, eventually the dissipative (frictional) and conservative forces, ubiquitous in real systems, couple to it to generate an emergent dynamics in which the swimming motion produces a force that is counter-balanced against residual gravitational forces.

I think this translates to "it just stops working after a bit". What's your take?
It seems that for this analysis using the current and projected fuel mix would make the most sense. There is no option at the pump purchase gas made from offshore crude for example.
> Sunscreen is regulated by the FDA unlike all other cosmetic products

Sunscreen is not a cosmetic product, the intended effect of the product is not cosmetic. It makes perfect sense to regulate sunscreen as a drug. I'm really glad if they aren't letting people in the US lather up their faces with sunscreen lotions that can't demonstrate themselves to be "generally recognized as safe and effective". People are using sunscreen more than ever these days.

If the products were so good that everyone would buy them over our tired old sunscreen formulas, and if they don't poison people or the planet, then someone will take the time and pay the money to meet that standard and they will make back their investment very quickly as they put every other sunscreen company in the US out of business. If no one has done that yet and you are so confident in these new sunscreens why not take a shot yourself?
> CTDs often remain undiagnosed for a long time

This seems to be a common thread, my wife's EDS diagnosis took more than a decade. It's a straightforward and obvious physical ailment. Even after her diagnosis she ran into problems - she once had to leave an ER without treatment for an unrelated problem, because the attending refused to treat her until she admitted that she was lying about her diagnosis. Hearing her stories and seeing first-hand how her medical interactions go has really shaken my faith in the medical system.

It's interesting, I seem to always see these comments on behalf of people who might find crypto useful to avoid local currency issues, not people actually doing it.
In the 80s or early 90s I read a surprisingly deep Logo programming book whose title/authors I forget. Not Turtle Geometry, but similar in coming from MIT Lisp/Scheme/AI people. One of the projects near the end was a kind of basic proof assistant. There was some discussion of OOP. It was written to go with some particular microcomputer Logo system.

Does this ring a bell for anyone? Maayybe this book? https://www.amazon.com/gp/product/0262510693/

Eh, it's more like... exactly what the title says: EVs are just more efficient.

1 gallon of gas contains 33.7 kWh of energy. [1]

The average ICE car goes 24 miles on 1 gallon of gas. That's 0.7 miles per kWh (24/33.7 ≅ 0.7).

The Tesla Model 3 goes about 4.1 miles per kWh. That's 5.8x further per kWh, or 5.8x more efficient!

Most of the difference is because ICE engines are inefficient. They waste energy. Just like the article says. :)

The point made by the article about the source of electricity from power plants was simply that EVs are more efficient even when charged from coal fired power plants! Your point about the "ICE in some power plant somewhere" is temporarily true... as the grid de-carbonizes there will be fewer and fewer emissions from grid-scale generation. (Nuclear + renewables is my personal guess for where we're headed.)

It's kind of sad that several threads here are playing devil's advocate. Unless some dramatically better tech takes the world by storm in the next 2-3 years, EVs are going to completely take over the market. Economies of scale should dramatically drive down costs over the next 5-10 years, and then all new cars will be EVs. No one will want the old, expensive, dirty, loud ICE cars. And this is really good news for everybody!

“It’s Potentially Illegal”: As Crypto Crashed, Coinbase Stopped Notifications
Ask HN: Anybody at Defcon?
My work flow changed from using one printer to using 8 of them. Octoprint is great but I haven’t taken the time or expense to set so many up since each would need their own pi. They are hard to find these days for a reasonably price. It was great when I did everything off the one printer though, I used an aftermarket runout sensor for filament on the gpio pins of the pi. I also kept track of my filament usage, used the webcam for monitoring from my house to the garage, and arc welder plugin to improve some of the prints. I am still a supporter of the program but I now just organize my SD cards neatly and manually sync them all with updated files. If my operation was bigger I would probably organize a networked solution like octoprint though.
It's not the idle at the stop sign that matters, it's the slowing and and re-accelerating afterward. Idle itself uses a trivial amount of gas - equivalent to around a tenth of a mile for a 15 second idle.
The title seems like a weird way to describe the phenomenon, given that the robot exists within our real space, which is essentially flat at the scales and velocities involved (specifically, non-relativistic ones). Is constraining motion to take place within a spherical slice of Euclidean 3-D space really equivalent to motion in an actually spherical space?

Unless I'm missing something, it's fairly easy to understand why it works. The horizontal weights use Newton's 3rd law to rotate the bar in the opposite direction from their own motion. The vertical weights are used to alter the robot's moment of inertia relative to the constrained axis of rotation. (You could replace these weights with a single weight that slides along the radial bar toward and away from the center axis.) The moment of inertia determines how much the robot as a whole moves then the horizontal weights move, so if you move the weights one way, then change the moment of inertia and move the weights back the other way, you get a net change in position. This is why it doesn't work with a cylinder: because when the vertical weights are constrained to a cylindrical space, moving them doesn't change the robot's moment of inertia.

I guess the point is that in a true spherical (or otherwise non-flat) space, any robot with the appropriate moving parts can do this "swimming" just by moving its parts in the right way in space without pushing on anything, essentially "pushing" against the curvature of the space itself.

Now that I think about it, there's a conceptually simpler way to demonstrate the same thing. Imagine a "robot" made of two parts: a "gun" and a "bullet". The gun starts on the "equator" of a spherical space and fires the bullet due west. By Newton's 3rd law, the gun begins moving east. After some time, the bullet flies all the way around the equator and impacts the gun from the east. The gun catches it and its velocity once again becomes zero, but in the time between firing the bullet and catching it, the gun has progressed some distance to the east, and now the combined gun and bullet system that we started with has changed its position. The gun can reload and fire the bullet west again, repeating the process as many times as necessary to continue progressing around the equator.
Seasoning is a reaction between the pan and fat. You're trying to create a thin layer of that reaction product (not just a coating of burned hydrocarbons). Any procedure that looks roughly like the following will be fine enough:

- Coat your iron with a heat-tolerant oil (peanut, avocado, ...) in such a way that it won't spill or make much of a mess. This usually includes very thin layers and maybe a drip pan.

- Cook it at 350-480F for 5-120 min. This often involves an oven, but you can do fine just bringing the pan up to high heat with some oil for a minute or two before you cook anything.

- Repeat as necessary.

The seasoning isn't critical for most dishes. Don't overthink it; just get the pan roaring hot once in awhile and start cooking in it. If you do manage to screw it up somehow (you probably won't), half a minute with some steel wool will make it easy to start over and try again.
You can do something similar yourself with an office chair and a pair of weights.

1. Hold both weights out in front of you
2. Swing one to the side.
3. Swing the other one straight up over your head (or just pull it in next to your body)
4. Swing the first one (off to the side) back in front of you.
5. Swing the second one back down (or push it away from yourself)
6. You are now back at (1), but the chair you're in has turned slightly.
> Roundabouts have a failure mode that 4-way stops don't, akin to starvation in computer science.

Putting roundabouts onto streets is not a binary decision: some intersections could be roundabouts, some could be lights, and others could be roundabouts with lights.
That's really awesome, but you need a tremendous amount of land to make that possible.
Very strong agree. Octoprint is incredibly slow, bloated, and just a poor performer overall. Klipper + Mainsail is such an insane upgrade that I feel like a fool for sticking to Octoprint for so long.

Using Octoprint reminds me of maintaining a bloated Wordpress + jQuery blob website, and then someone shows you a snappy React version running on a cached edge provider. Night and day difference.

Klipper and Klipper based UIs are making huge strides. They are just so responsive and capable.

I don't know anything about common lisp, this seems to be a problem where Julia would shine marvelously.
Given that most Julia users tend to be excellent mathematicians and physicists, I would imagine any advances or performance improvements in these types of calculations from the literature could be developed in Julia in a faction of the time that Fortran or C would take.
In this case (numerics), the performance of Julia actually would probably be just as good as Fortran (or potentially faster due to being able to implement new ideas where performance enhancements quickly).

Hang on. Capitalism means private ownership of the means of production. It sounds like you are talking about choices made by consumers.

Communist systems have consumers who make choices, too. Soviet citizens were perfectly free to choose which goods to queue up for.
Please note that Octoprint and Klipper are at different levels of functionality. It's not a choice between the two in any way.

Octoprint is for job management/monitoring and is SUPER extensible. It gives you a web interface/camera view/manual control of the printer. You can do things like install a slicer plugin so you can drop an .stl file into the browser then it will slice and print.

Klipper is more like printer firmware. It's lower level than Octoprint.

The two can be used together.

They effectively weigh less when they're far apart.

If you look from above (like their video), the curved track means that projected down to the plane it's rotating in they're closer to the axis.
