Yikes!!! Who keeps critters like squirrels, dogs, etc. off the course? I've ridden a lot of fast long twisty visibility impaired descents on a bicycle, up to about 55mph (not 136mph), and have had plenty of opportunities to evade obstacles, moving or not. Been involuntarily airborne a few times. To be sure I enjoy it as one of the most enjoyable activities of my life, but... that video is orders of magnitude more terrifying.
I have a pretty libertarian steak, but I do sometimes think that banning advertising in general might be so beneficial for society that it would be worth taking the free speech hit. Not sure how in the hell you enforce it though. "What is an ad?", for example.
It is! Although they are being used in a really weird and not normal way here.

I found "The Little Book of Rust Macros"[1] to be a really good resource for getting started with Rust's declarative macros.

The article says 1000 kilograms, that is 1 ton.
Vim is not only an editing language, but a fast-starting editor with a small-ish native executable, and small run-time memory use.

This facet is typically not ported into other editors that have a Vim mode.

Vim runs natively inside virtual machines and containers, on resource-constrained embedded systems, and on remotely accessed machines.

Another aspect is that Vim can be operated entirely using a terminal emulator, and so can be running on a remote host to which the use only has a SSH or serial connection.
> And they’re always frustratingly incomplete and/or buggy.

Have you tried evil-mode (Emacs VI Layer - E.V.I.L.), an implementation of the vim-bindings in Emacs? I've heard it works very well.

Or, at least, the Emacs subreddit seems to get a pretty steady flow of people who come from vim and get into Doom Emacs, which has evil-mode (and lots of other stuff) pre-configured and ready to go.

They seem very happy, from reading their reports, anyway.
Here is a visual proof for the Pythagorean theorem:

https://www.dbai.tuwien.ac.at/proj/pf2html/proofs/pythagoras...

I find this much more "useful" since the Pythagorean theorem isn't immediately intuitive to me.

As for the proof in the original post, it seems really redundant to me. it follows from a (b+c) = ab + ac.

And while building intuition for this distributive property of multiplication is extremely essential when teaching maths, I feel that the intuition for why this is true is better built without leaning on geometry.
Yeah when you live in vscode vim mode you learn to completely avoid certain vim features

Light on the details. Most of the studies cited are very "initial design study" type, far from a plan fleshed out enough to make a possible/impossible decision.

"They examined the acute as well as chronic effects of EMF exposure and found a significant increase in adrenaline and noradrenaline levels after EMF exposure, following a drop, but the normal levels were not restored even at the end of the study (about one and a half year). They also observed significant diminution in dopamine levels."
I don't trade so my comment is low value speculation, but it's more about what a crystal ball is.

revealing the future doesn't give free insight into the dynamics that produced it, and you don't need to know the future to identify where a dynamic among factors or parties may be in play.
> My aim was to configure my home's heating to switch off when my family is away and turn back on when we return. This is achieved with home assistant, a popular open-source home automation platform, with location/presence notifications from mobile devices. To do this, the home assistant server needs to be accessible from the internet, as mobile devices must communicate with it remotely.

Does it really need to be accessible from the internet? I've never used Home Assistant so maybe what follows would not work, but how about:

• Your mobile device could upload the location/presence notifications to a server outside of your LAN, such as virtual machine at an inexpensive hosting service like Hetzner or Amazon Lightsail.

Something on your LAN could poll that and talk to the Home Assistant server.

• Your mobile device could email the notifications to you. Something on your LAN could monitor your email and process the notifications. A good tool for that is imapfilter [1].

No, but I've used a scanner before. Surely that's still an option?

Maybe it's unusual that we've kept them, but both my ancient inkjet and my wife's ancient laser printer both have flatbed scanners on top.
In 1997, remains of a deceased newborn were found at a campground. Police investigated, found no suspects and it became a cold case.

What happened before: A woman gave birth unexpectedly alone, at home - which had with no cell or landline. She tried to self deliver in a bath tub and the baby asphyxiated. When she recovered enough, she wrapped the remains and left them at a campground.

From this, the police are charging her with murder (for failing to seek medical help) and concealing death. Each carries a life sentence.

I think this post is a good example of why people buy rpis: network effects. Are people writing articles like this about the competition? Especially if you're in to modding, hacking, etc the community around the product is an important consideration.

The expression immediately follows from

a ( b+c) = ab + ac.

I agree it's important that students intuitively feel that

a ( b+c) = ab + ac

is true.

But once we are at that, why would we even bother to teach or "proof" all variations of that expression?

Could you elaborate?

Motivation: looking at racket these days, and have ordered "how to design programs" in the library :)
I've made it explicit what I believe safe means. I could discuss it in more detail, but I won't be changing my definition.

I would never do such a barbaric thing as adding a non-inheritable class to an object system. Or, if I were convinced to, it would be purely for performance, not as a way of restricting the programmer; i.e. for speeding up things due to the compiler knowing that the class is final.
True, but are people turning off ECMAScript/WASM in their browsers to avoid this? As an app developer, I want to know if my app will keep running. In the Java Applet days, at some point the security scares became frequent enough to cause articles like "Turn off Java except on websites where you are actively using it". Once your users have to find and toggle a setting to make your app work, your audience size drops significantly.

I don't see such fears around ECMAScript/WASM. Since the dominant players have a vested interest in users feeling safe leaving those technologies turned on for all websites, they'll keep investing to maintain that safety (and the marketing of that safety).

This is a massive insurance policy for building a TeaVM app -- the foundational web technologies it builds on are receiving incredible investments from industry heavyweights. It's not just security that is maintained, new Web APIs are regularly developed too. Want to use USB from your web app? No need to wait for Oracle to roll out a Java API for it -- browser vendors have made a new API and you can call it from you TeaVM app right away.
I'd qualify that phrase as, "seeing how the factory sausage gets made".

Social media at the start may have been neutral to slightly negative, but once creators started optimizing and the various "algorithms" were installed and A/B tested, what came out the end is some pretty nasty stuff mentally. Junk food for the soul.
> You have to be better than the bad players

That is easier with fair opponents. Cheating could help the worse poker player to win.

In a field of apple tree, the best/fast/cheater climbers got the most apples but eventually everyone showing up can pick one or patient for the next season.

Pocket and finance needs at the very least one looser for the others to win something. Others cheating and you not, does lower your chances to win.
It's not just climate change. Roughly speaking there are three goals around environmental regulation:

1) preserving at least some nature and biodiversity. Not much elaboration needed, we are causing a mass-extinction, some would like to limit the impact of that. And we profit from some of those species too

2) Climate Change. This one gets all the media attention, and it is a valid cause. Most Western countries are in a relatively good position in regards to impact of climate change, but even for us any dollar spent today to fight climate change will save us multiple dollars over the coming decades. We can deal with extreme weather and build better costal fortifications, but those things aren't cheap. Also nobody wants to deal with the upcoming migration crisis as poorer countries become ever less livable due to climate change

3) Imminent Health Concerns. European cities suffer from high concentrations of airborne particulate matter, primarily from residential heating and car exhaust that lingers in the air in densely built cities. This is the primary reason city centers become inaccessible to certain vehicle types and governments push for heat pumps. Particulates are linked to a range of health issues. Heart disease, respiratory infections, chronic lung disease, cancers, preterm births [1]. Sure, China is much worse, but that doesn't mean we can't make people's lives better and save on health care costs by reducing the amount of particulates we emit in densely populated areas

If you show an LLM one webcam feed to train on, that's useful. Two is even more useful. But there are diminishing returns. "Useful training data" is limited.

Humans get to PhD level with barely a drop of training data compared to what LLMs are trained on.

If there were infinite useful data, then scaling AI on data would make sense. Since there isn't, the way forward is getting more efficient at using the data we have.
I'm all for capitalism, but still don't understand how people can work in that cost-cutting department.

Yeah, nice on paper, easy to shout all the time, and I agree. But - even if whole Europe went to caveman era, we won't make dent big enough to matter at all or change trajectory of future in any significant way. We are just little above 5% of the world, even if we pollute more than average its just a small drop in a bucket. But we are literally destroying prosperity in whole Europe, while most of the world gives significantly less fucks about this topic so we endeavor on some quixotic quest for glory where none is found.

That's the problem with well-meaning fanatics - you can't discuss consensus with them, middle ground is their ground only. Even extreme moves are never enough. So what we are seeing - people like trump who don't give a fuck about environment are winning, slowly but surely. There is no reversal in next decades, its hard to accept since I wish it to be true but it won't.

Inability of far eco left to have any sort of meaningful dialog and find middle ground is the reason why all these at glance well-meaning policies are going to backfire massively, and they already do as OP mentions. Why should we head to poverty while all developing world coast on us, steal our tech like germany's solar cells tech and we are just left behind.

I'll never vote for any green-related party despite being a massive nature and wilderness lover. Those people are literal personification of 'road to hell is paved with good intentions', IMHO a form of simpleton's eco-terrorism.

What is area? Do you find the the basic concept of area (or the relationship between different dimensions in general) "doesn't click"?
I don't think this is true at all. If you have a bunch of engineers at the table, they have plenty of topics available, yes, but say you add a medical doctor to the mix, you've suddenly unlocked the topic of how the two professions compare, interact, overlap, etc. With just the engineers, you don't have that, outside of surface level speculation.

9/11 is a great example here because even if you knew it would happen a day in advance, trading on that would gain you nothing in this experiment - the markets didnt open that day.
Because the Qualcomm and Nuvia ALAs have remained secret, we cannot know whether Arm really has the right to revoke them at will.

It is hard to believe that anyone would accept to sign an ALA that can easily be revoked, because whoever signs an ALA intends to invest a lot of money developing products based on it and there is no doubt that all the invested money can be lost if the ALA is revoked unilaterally.

It remains to be seen what will happen at the trial.

Hmm, maybe send children with no primary attachment off to battle school?
Disclosure: I work for a social media company. However I live in the UK.

Most schools in the UK ban phones in school. The difference here is that in this study phones were taken away for 21 days, even after school. They lost access to the phone completely during that time.

I am less convinced that we should wholesale ban phones for kids, because in the UK at least, there is no longer any culture of letting kids go out and socialise. We need to provide spaces for kids to be kids, and safe.

However I do think social media use should be severely restricted, unfiltered video being zapped into young minds is not the way to build a cohesive society. tiktok/reels/youtube should probably be editorialised so that we can avoid the stupid, bullying and dangerous stuff being spread by arseholes.

Furthermore I think phone use should be time limited by default. That is, the default is that the phone stops all notifications after 20:00 apart from things like parents.

I have two kids, and I despair at other parents who think its fine to allow their 10/11 year olds to start group video calls at >20:30. Or the ones who let their kids bully on the class whatsapp.

Part of this is education, most of it is tech companies wanting to make money from kids (including mine.)
I'm pretty fine with restrictions on usage during class time - but not by direct remote control of such personal devices. The goal is to improve education and prepare children for life in the modern world. That can't be done without a smartphone, the most important item of most people that they use to run their lives. Today, many normal people don't even have desktop computers, they do everything on phones. That has privacy implications on what is reasonable to do with a person's phone - even a child has right to their privacy (in reasonable limits of course).
Yes but preventing what we can of it at this stage (which isn't much) will cost as much as a world war and will have huge impact on people's lives. So will climate change but not as equally distributed. Many areas will be fine and some will even improve (eg Siberia and Northern Canada might become a lot more habitable. The Soviets even had a plan to screw up the gulf stream by damming up the Bering Strait for this purpose.

I just don't see it happen. Most countries are democracies and turkeys don't vote for Christmas. It's not fair and I don't agree with it but it's realistic.

Add to that the 20 year delay in CO2 emissions and effect and most of it is already locked in.

When you’re young, if your startup fails, you’re still young.

But when you’re in your 40s or more, and your startup fails, it hits you harder, you lost some last good years to the stress of building a startup, for nothing. And now you’re even older and more tired.

It’s like there’s no point unless you’re sure you have something very promising, not just snake oil BS. Better to spend time with family and your hobbies.

What’s the point of getting rich at like 70? You’re old and all the romance of life has been drained. Your wealth just pays for better end of life care.
Divorce isn’t a bad thing. If you’re looking for ownership of people, marriage is a poor choice.
Think about it from his perspective.

Data from the internet can be chunked, sorted, easily processed, and has a relatively high signal-to-noise ratio. Data from a webcam or a microphone -- if even legal to access in the first place -- would be a mess. Imagine chunking and processing 5TB of that sort of data. Seems to me that the effort would far outweigh the reward.

Robots are a different problem entirely. It's darkly amusing that simple problems of motion through space are more complex to replicate than painting the simulacra of a masterpiece, or acing the medical licensing exam. We'll probably have AGI before we can mimic the movement of the simple housefly.

The Invention That Accidentally Made McMansions
> the entropy of a thermodynamic system is proportional to the amount of microstates (positions, types, momentum, etc. of individual particles) that would lead to the same macrostate (temperature, volume, pressure, etc.). It doesn't matter if an observer is aware of any of this, it's an objective property of the system.

The meaning of "would lead to the same macrostate" (and therefore the entropy) is not an "objective" property of the system (positions, types, momentum, etc. of individual particles). At least not in the way that the energy is an "objective" property of the system.

The entropy is an "objective" property of the pair formed by the system (which can be described by a microstate) and some particular way of defining macrostates for that system.

That's what people mean when they say that the entropy is not an "objective" property of a physical system: that it depends on how we choose to describe that physical system (and that description is external to the physical system itself).

Of course, if you define "system" as "the underlying microscopical system plus this thermodynamical system description that takes into account some derived state variables only" the situation is not the same as if you define "system" as "the underlying microscopical system alone".

What research?
If the results of the study had gone the other way, would anyone have changed their minds about smartphone bans? Or would they have just pointed at the limitations of the study as reason to disregard the findings...
Visual proofs can be deceptive. For example, you have the famous missing square puzzle, where rearranging pieces of a triangle causes a square to vanish, something that should be impossible.

It doesn't mean it is not possible to have rigorous visual proofs, the one in the article is, but doing so can be deceptively hard. It is also common for visual proofs to be less complete, for instance, here, it only covers the cases where a>0, b>0 and a>b, there are no such limitations when doing so with algebra. I guess you can tweak the visual proof to account for these cases, but it will become far less elegant.

So I understand why teachers avoid visual proofs in math classes, they actually want you to stay away from them. They have entertainment value, that's why you see them so much in pop-science, and I think it is important, and also some historical value, as they were much more present in ancient times, but to actually learn maths, not so much.
That is unless you are studying visual proofs specifically, but I think it is an advanced topic you would tackle well after you can master simple equations like a^2 – b^2 = (a + b)(a – b).
