(UK kids are not smarter!)

Just to add when I mean fractals at 7 and 8, I don't mean the hard maths or the programming, for sure.

But some ways to imagine the context of the hard maths.

Like how to recognise fractals (or just self-similarity) in nature, or explore drawing some by hand, that is a really crucial thing that a seven or eight year old should be introduced to. Why are leaves like trees? Why is broccoli simpler than it looks? River deltas, snowflakes, you know...

Kids are shown lots of these things -- and they often notice self-similarity without prompting -- without being told that there is a unifying theory. The unifying theory is amazing in and of itself, and can be demonstrated with a Logo turtle.

(Which brings me onto another thing... where the heck are all the logo turtles)

There's a long and broad tradition in the UK of the "Christmas Lecture" now (started with the Royal Society which is televised; it's what a TED talk is, but better). All-ages family learning, made fun and accessible.
When things cost money to produce, funders get more input. That said many TV and film projects are the vision of a single auteur, when the auteur has the pull to get total creative control from funders or else funds his own project. It’s just that this person is a director or executive producer instead of a writer.

Math is all around us, and it's nice to have a gut-level check on whether or not something makes sense.

Say you're at a restaurant, and you and your other both ordered $25-ish dollar entrees, and $10-ish drinks, and split a $15-ish appetizer, and the bill comes closer to $150 than $100, something was probably mixed up.

That kind of quick approximation gives you a nudge to check real numbers.
Good point about break pads, I completely forgot about those.

The thing is, that's another aspect where I'd naively assume tires are a much larger factor. I'm probably wrong, though.

I feel this way about UIs that are never stable enough and not configurable enough for us rubes to be trusted laying it out how we want.

Software is so flexible, yet we can't make UIs the way we want and are constantly subjected to the whims of designers and the buffets of fads. No way anyone becomes a master of using software because software apparently doesn't want that.
The main benefit is that I know mental math makes my brain sharp. I can't believe the difference it makes, and that it is not more widely known and practiced. However, it takes discipline to make it a habit, which isn't a very popular thing.

Any practical utility is a distant second.
Why would Russia hit Toyota? They have more important stuff to hack right now.

China on the other hand, has a new auto industry to take over the world.
The worst part of this trend to me is how many games sacrifice their identity to fit the mold that is now most profitable, it feels so soulless. This is all from my own experience/memory.

Every game needs live service, seasons, and a battle pass. While I appreciate that it can keep the game fresh and evolving over time, I think a lot of times its harmful. Sometimes a relatively simple game is blown out of proportion over time and id almost rather a stagnant game. Furthermore, gameplay can suffer too. In my opinion R6 siege started really strong, but has gone downhill recently, most obviously in operator design. Real power creep is sometimes an issue as well, somewhat recently I remember there were one or two operators added that felt like almost direct upgrades to base game ones. In its case, both the art style and operator design suffered from being stretched out for so long. Or RDR2, who sells most of the content through their premium currency and whose movement between the single player and online is so drastically different that fights online look like smash bros melee matches with frantic strafing and rolling. Compare this to titanfall 2’s design, which has remained stagnant (because it was killed a long time ago), but incredibly successful maintaining a large player base to this day.

Cod and pubg have sacrificed their art style and aesthetic, MW went from “realistic” tactical characters to jigsaw puppets and neon, out of place outfits. It’s like power creep, but for ridiculousness, skins have to get crazier and crazier because sometimes it keeps people buying them because its funny. It fit in fortnite because it was cartoonish and ridiculous from the beginning, but through MW and CW lifespan you can see the art style gradually decay. These game aren’t really meant to be taken seriously, but it always kinda put me off. Not necessarily making an argument about my taste, but rather how the games stray more and more from their original vision, driven by micro transactions.

Battlefield has thrown out their traditional classes for specialists following in r6 and other hero shooters footsteps, part of me always kinda felt like it was to sell skins for each specialist, but I might be wrong here.

This isnt the biggest deal, especially not within the games industry, but frustrating to see innovation slowly be stamped back into the mold. There are many games that hold true to their visions or fill these voids, but the state of AAA gaming and how it molds to the market is a little disappointing to me.
A three star restaurant really is something different. It’s not just the experience, the quality and consistency is just something that’s hard to find elsewhere.

The best cup of black coffee I’ve ever had was at a three star restaurant. It was just a simple cup of coffee but it was just made completely perfectly. Great beans I’m sure, a good roast, brewed exactly the right way. You can of course get that outside of a Michelin starred restaurant easily, but the point is in a three star restaurant everything is perfect, even the cup of coffee you have after dinner. They didn’t teen me where the beans were from or who roasted it, it was pedestrian for them.
Off topic but in a sci fi hypothetical, would there be a way to make out sun bigger to go supernova ?
They call it black market because a black market is not the same thing as a free market, otherwise they would just call it free market.
I hate when Occam's razor is applied to non-scientific domains, but this is clearly a scientific domain, and it applies here - multiverse theory is the simpler of the two explanations.
Async/await requires a run loop. Async functions are special functions that can suspend execution and jump back to the run loop, and at some later point the run loop continues them.

Normal functions can't do that. If they wait for something they block, they can't give control back to the run loop.
> Other than research, what is going to be possible on Mars that isn't possible underground for cheaper?

Mars, or any location well beyond easy reach of the Earth-Moon system for that matter, act as forcing factors for the development of truly independent self-sustainability, and thus also all of the various technologies required to do such a thing. Even on the moon, the presence of a eject lever (ability to return to Earth relatively quickly and easily) and fast and “easy” resupplies greatly reduce the impetus to become self-sufficient.

Mars would also serve as a great stepping stone to vastly larger and more ambitious spacecraft. Its reduced gravity and aerodynamically insignificant atmosphere along with the raw materials available on Mars along with a relatively temperate climate and Earthlike day-night cycle make it a good candidate for use as a shipyard for building and launching extremely large interplanetary freighters and the first permanently spaceborne non-orbital crewed crafts — something that’s not feasible in Earth’s orbit due to the need to tow all the raw materials in, and less suitable for the Moon due to its greater extremes and deficiencies in readily available resources.

So in short, Mars is really more of a starting point in humanity’s permanent inhabitance and traversal of space with potential for huge gains in science and technology applicable to problems on Earth than it is a goal in and of itself.

> Right, but there is the opposite concern as well. By trying to do this too soon we underfund arms control or climate change response at the margin and we suffer extinction or societal decline.
> For me it's about resources. It's true technology takes actual effort, but it generally speaking takes less effort over time due to exponential tech. If the folks involved in the manhattan project had just ONE modern computer it probably would have halved the timeline / resources required. My argument is that if the goal is species survival there is much, much, much lower hanging fruit to go after.

The resources being sunk into space right now are couch change relative to practically everything else, and a company like SpaceX pursuing long-term settlement of Mars would only increase that to pocket change (at least in terms of usage of taxpayer funds). Vastly larger sums are spent on the military and even wasted on utterly broken government contracting and procurement, like the $20,000 routers that were purchased for hundreds of tiny libraries in WV[0] where $60 consumer grade routers would have sufficed.

There is no lack of resources, only rampant mismanagement, waste on titanic scales, and lack of will.

I used to think about this deeply, and have flipped the idea around - why can't we be doing more work (including writing and other computer work) outdoors?

As a start, I've started https://www.reddit.com/r/ErgoMobileComputers/ and been going on stretches of doing laptop work outside more. By having a setup where you've either got the screen closer to the face (less glare) or an e-ink display, I've managed being outside for up to a few hours.
This case is obvious. So fix the law, it is / should be easy to close the loophole and move along.

It's another strawperson argument. It's not all one or the other. Reducing your energy consumption is not sufficient, and I don't know anyone who says it is.

The idea that individuals are powerless is antithetical to democracy, which IMHO is why the reactionaries push it. They say the same thing about protests (despite a long history of success) and any other individual/collective action. Democratic government is a form of collective action, and so they decry that too. They want you dependent on strongpersons and corporations, and IMHO by buying into it, you are surrendering your power and (unwittingly for most) doing nothing less than fighting agaist freedom and democracy. Collective action is quite powerful - ironically, the reactionary movement uses it heavily, and is the foundation of a free society, as is individual responsibility. (It's also the foundation of a free market and SV-style entrepenurialism - individuals doing something in their garage and changing the world.)

Communities, society, depend on everyone doing their part as individuals. You can't prevent trash on the streets in your community by obstaining from littering yourself, but we do keep the streets clean in large part by each person not littering (and we also obey the law, help people in need, etc. etc.).

Reality is quite the opposite of reactionary propaganda: Individuals acting works incredibly well. The Minutemen in the American Revolution were volunteers, who defeated the subjects of the British King. After centuries of unprecendeted success in human history, it's incredible that people abandon it simply because of propaganda.

I don't know you, of course, and it's just one comment in one moment in your life, but the parent comment is clearly anti-progressive.
> Teslas come out poorly on this because they are a performance-focussed car with large, soft tires.

Even the Model 3? That's more of an economy car, I'd expect it to have practical tires.
I expect them to be firesaled by the oligarches themselves. Get them liquidated before they're frozen, and get that desperately needed western currency that doesn't need to flow through embargoed Russian banks; a desperation life raft.

This is a much harder problem than it might seem. You would need to find an underground storage site, where you can rule out any geological effects for a hundred millennia. In those time frames, even rigid rock moves quite a bit. There is no container solid enough, it can't be crushed. You would need to prevent any water coming to that place and carry the contamination away.

I don't get this doom and gloom. The population of Hawaii is 1.3 million, a third of the oil is from Russia. That is minuscule on the world scale. Oil is an extremely liquid trade, and Hawaii is already buying non Jones act oil.

Jones Act itself is a problem, and a blessing. It ensures a US maritime industry but has due to lack of competition left it so far behind the world standard that the minute it is removed the entire sector will go bankrupt from international competition.

Michelin also gives out an award for 'good quality, good value restaurants', called the Bib Gourmand, which is worth looking into. Bib Gourmand restaurants are often still a bit more expensive than the average restaurant in a place, but are generally of very very good quality and value for money.
That still trips me up from time to time. I'm not sure why anyone ever uses percentage increase to communicate anything.

Just say the quantity increased "from 0.0015 to 0.002" or something.

A simple UI on my phone that tells me how many steps I have and a progress bar was enough to make me religious about getting my 10k steps each day, and it's been nothing but a good thing in my life. I even got my girlfriend addicted.

I cant tell which keyboard they are actually selling. Most of the pictures show a sleek split keyboard with buttons that look programmable -- especially around the thumbs, but on the buy button and store -- its a square, generic looking split keyboard. Am I missing something?

It's tricky going from an engineering mindset to risk management. I still struggle with it and have been in the industry for a long time. You can't falsify risks and many of your inputs are going to be guesses based on an amalgam of experience, historical information, trends and available risk/threat models.

Today there's all of these metrics available that give it the feel of an exact science, but its not. It's educated guesswork, but there's enough evidence showing it works that its worth substantially increasing the costs and friction of doing business to align with its outputs.

Usually.

In this case something arguably failed in the process. It's noteworthy but it's not an existential threat to Toyota. They will learn from it, someone's probably going to 'seek opportunities outside the firm' and they'll get back to making great products.
That's true however there aren't currently any other viable batteries chemistries with the density offered by lithium based chemistries.
I just stopped reading the news pretty much. It takes like a week or two and then you won't even notice. Look at it this way, if anything super important happens you will most likely see it on the front page here or on the front page of Reddit. But with HN and Reddit you don't get the bulk that is made to fill the page on a news site.

>What if Russians (the ones with power to do so) decide to take the world with them?

Traditional military is being wrecked by underdog Ukraine and probably massive proxy war. Russia is losing big time.

Evil will burn down the world to rule over the ashes.

Everyone is looking to the Russian people who must prevent this evil from happening. They must rise up and overthrow their government.

Lets be realistic, if Russia does nuke the world. Literally nobody can sit back. The nuclear winter and nightmare of Earth would harm them just as much as anyone else. Even if the prediction of nuclear winter isn't true... it's only a matter of time that Russia goes after everyone else they didnt nuke already.

The entire remaining world immediately lays waste to Russia after they do this.
Most devs who use something like Postman in their normal workflow would prefer a standalone client (or cli).
I could be wrong but I don't believe there's enough mass in our solar system for it to be close. Solar systems do merge with one another, stars bring other stars into their orbit, etc. It would take something like that, I believe.

Reminds me of when people routinely (and entirely legally) use tax loopholes to avoid paying tax. The problem is that no one even tries to pay a dime more taxes than is legally necessary.

And yet those people are routinely attacked instead of the laws themselves, which to me seems completely absurd. A person should no sooner pay "the spirit of" the amount of tax they "should" owe, than the IRS would forgive a restaurant some tax during the pandemic since "the spirit of" tax wouldn't sink businesses temporarily set back by pandemics.
It's conceptually a different thing to "await" and to "stop execution till the thing I am waiting for happens"

In the first case I am telling an executor what it has to do (it has to execute the thing then continue inside my function)

In the second case I am myself blocked into a state that will be unblocked when the thing returns.

That is in the first case my function must be of a type that can be stopped and continued and I need to save its state somewhere.

In the second case I don't need the ability to stop and continue my function.

That makes for two kinds of functions at some level. Low level languages will expose that. High level languages will hide it.

But there is a growing request for functions that can be both. I think that zig has them
This process works, but in my experience it also leads to the naive implementation. Which isn't always bad.
that's so awesome, thank you!
What's the point of sealed records then? How would that be managed? We should let citizens have some privacy right?
Some better questions to ask - based on both histories of the U.S. and Soviet/Russian nuclear chains of command, and well-known rumors that Joseph Stalin was murdered by his inner circle:

1.) If Putin actually ordered the use of a nuclear weapon (in the current context in Ukraine), would his order be obeyed?

2.) If {same situation as #1}, would Putin quickly be removed from power, for being too dangerous for even his inner circle to tolerate?

3.) How confident is Putin that he knows the answers to 1.) and 2.)?
China has willingly accepted to support Russia confront NATO directly and said Putin they will help in case of unilateral sanctions from the West. China may not try to backtrack a bit, but that support directly enabled Putin to invade (even though China may not have been given the details).

China must pay for that.
Most teachers don't seem to particularly like working from home. They became teachers because they like working with children. They can't do that as effectively at the other end of a screen.

Most teachers I know want to get back to the classroom. They just don't want to risk their lives for it. They are often older and often have co-morbidities that put them at serious risk from COVID.

So they're not dragging it out to escape work. Unlike "the rest of us", working from home isn't an opportunity to slack off without the boss watching. They often work even harder. They being cautious because they don't want to die.
A little bit of googling reveals that I am not the only person to have this question.

To summarize some answers:

a) Energy is conserved by anyone performing an actual observation, therefore energy is conserved. (I suppose this is the 'shut up and calculate' answer.)

b) MWI worlds are actually entirely separate non-interacting universes that just happen to have the exact same history up to the moment of 'divergence.' Therefore energy is conserved.

(But why does world B exist in the first place, waiting around for this specific point of divergence? Are there just so many universes lying around that we're guaranteed to be able to find two that reflect both sides of a given coin flip? Or are the many-worlds realizable as the 'closure' of events from any given world-line?)

But I suppose all of this points at MWI being internally consistent but deeply unsatisfying. Any attempt to chase implications puts you in 'we can't answer why' territory.
