> The problem is one of understimulation

The problem (for all the students, not just the cleverest ones) is that school curriculum is necessarily insipid, and school pedagogy provides very little direct practice and delayed, often unhelpful feedback. A huge amount of time is wasted on organizational overhead, other students can be tremendously distracting, and meaningful learning is often cut off by scheduled class changes. The primary focus is on memorizing and regurgitating atomized and decontextualized definitions, factoids, and formulas, and students are discouraged from asking and answering their own questions, solving their own problems, or doing their own research. Perhaps worse, there is an excessive focus on getting the “right answers”, which discourages risk taking.

Motivated students who have learned some meta-cognitive skills can often learn entirely independently without any human interaction more efficiently than they can from a typical classroom studying a typical school textbook and doing assigned homework.

Working 1:1 with an expert tutor/mentor/coach for at least a few hours per week (and then spending the rest of the time on independent practice) is dramatically more effective. Of particular note for clever students, this allows for students to try problems and projects of much larger scope and much greater difficulty than the typical curriculum has room for. But nobody has figured out how to scale this affordably to the whole society.

One lucky thing in the software industry is that the tools are very interactive and there are lots of opportunities to get various kinds of feedback even when working independently.
Mario Kart is now banned in my house. My youngest never wins and he never takes it well. Mario Odyssey is everyone's jam. They kinda like Minecraft on and off.
The article is talking about our image of "successful" not "smart".
>The best scientists don't make good managers

This brings up an important point. People are good at different tasks.

Some people are exceptional with gleaning and regurgitating information from texts and lectures. This is what we mostly label as "smart" today.

Others can be great at different things, such as any of the vast sets of social skills, critical thinking, maths, strategy, etc.

The problem is that while intelligence in one skill is correlated with intelligence in another, it is not necessarily the case.

We probably all have met engineers who openly admit they're not the greatest writers. Another example was one I learned from my interest in chess. Bobby Fischer was one of the greatest at the game, but notoriously struggled with memorizing opening game lines and theory. I am sure many of us here have also met engineers and academics with a lot of knowledge in their field, but whom also hold missconceptions, or easily come to factually erroneous conclusions on things which they have not studies.

When I read the story, I was a bit incredulous at the author's words that "IQ is real and it does matter," not because it's such an obvious over-simplification.

However, universities will be reluctant to disavow their beliefs in the mystical IQ--an idea which rests in the scholarly literature as an estimation of G, general intelligence--as this is a set of institutions which benefits from their faith not just that it is something which can be measured on a test, but that they do accurately measure it.

They're running in circles with this "medium brilliance" because they're out of ideas about why their faith's predictions failed. Turns out those who score the best on IQ tests are those who are the best at scoring well on IQ tests--not the same set of skills needed to be the best scientists.
You mean you're modifying files stored in Dropbox from your phone? What sort of editor setup do you use?
You’re assuming they’re using a linear controller, and they’re way ahead of you [1].

But I don’t think they’re overshooting per se. I think they’re landing the centers in the right place, but the outer pieces account for most of the moment of inertia, and they’re flexible, so the overall assembly is deforming. Deriving the optimal control law for that could be a bit messy. I would guess that it involves bringing the center piece nearly to a stop slightly short of 90 degrees and then gently bringing it the rest of the way.

Quite a few. What makes you think subsidised businesses should be propped up at the expense of more massified and efficient ones?

There is no justification for differential taxation of business structures. Competition should determine the appropriate form.

And never forget that to pay tax you are in receipt of recycled government spending. In other words your income is higher than it otherwise would be. Government doesn't save. It spends.
there are already many peak-storage solutions deployed and none of them involve hydrogen

That seems like an overstatement. There has definitely been considerable research into using hydrogen as "peak-storage solution", and I think some approaches are actually being deployed. For example, here's an NREL story from last year: https://www.nrel.gov/continuum/energy_integration/hydrogen.h...

The article agrees with you that the current inefficiencies of the round-trip to the grid are large, but claims that generating hydrogen as a vehicular fuel using excess solar and wind power does make sense. So if the parent was envisioning those "giant fuel cells" as being mobile (or located somewhere really remote), then he's not that far off.

Fwiw a couple days after a renown expert said to me (in so many words) "soon...we can so this..." this happened:

https://gizmodo.com/chinese-fusion-test-creates-90-million-f...

We built the bomb.

We put human on the moon.

But we can't do fusion? And it's the one we need most?

To play on Thiel's quote, thank god Twitter doubled their character count. Now that's an amazing advance!!!
Hmm, you're right. The linked article didn't mention fusion.

That website is such a mess though that I wound up on the main page unintentionally, and there was an article: MIT researchers say nuclear fusion will feed the grid “in 15 years”

I didn't realize they were separate.
From potentially incorrect memory, one can find the actual optimal solution pretty quickly, but that needs a giant lookup table that functions like an end-game table. Their lab might not have a machine with enough memory. Keep in mind that it would be a net loss if the solver took even 15ms longer.
Rather than "maximum", don't you mean the largest minimum is 20 turns? I'm pretty sure I can do 21 turns and not solve it.
We changed the URL to that from https://www.theatlantic.com/science/archive/2018/03/quantum-....

For the Vitamin D in particular, there's recentish news that suggests most people in general may be somewhat Vitamin D-deficient and that the recommended daily dose should be sharply raised.
Electricity to heat is not that efficient; normally district heating systems run off of the waste heat of electricity generation. Are you talking about an example where the waste heat isn't enough to power the district heat?
My Pokémon games still hold their saves, about 20 years after I got them. I turned on my GBC and checked a few months ago and the saves were amazingly still there then.

I want to dump the save files but I haven’t quite found the right equipment at the right price. Does anyone know of some electronics that are not too expensive and that can be used to dump the save games onto a Linux computer?
Yea, it's the maximum over the minimal solutions for each configuration.
A form would allow a team to define what gets entered, just like a checkout form defines a sellers needs. As it is, it's left up to human memory. That's flawed. I thought we knew and agreed on this.
To me, the promise of Servo was that we could incrementally rewrite Firefox in Rust, evolving Rust alongside it, and solve memory corruption in a browser, making a giant leap forward for security. Servo was the credible alternative to Chrome's approach of just adding more sandboxing. I'm just disappointed.
This place is trying: https://viome.com/

My guess is that human flora are orders of magnitude higher in complexity. They all interact with one another and diet. It’s hard to find numbers, but at least one place indicated over 500 different strains in the human gut.
His criticism is reasonable. There is a line between valuable criticism and pointless negativity. The latter deserves the “if you don’t like it, go away” response. The former does not. The line is fuzzy, so err on the side of leniency.

Now, if there is a flaw in the criticism, address that, not the mere fact that it is criticism.
Thanks for the suggestions. I hadn't heard of those, but they sound really handy. I'll try them out.
As one example of a new buyer who can use bursts of electricity: If you have a large number of electric cars with big batteries, which don't have to charge every day, and they're plugged in both at work and at home, you can do a lot of good by having them charge when electricity is cheapest.

And it's not exactly high-tech, it's just a little bit of schedule prediction.
I don't know why Californians put up with this mess from their politicians.

In Texas, one company maintains the infrastructure
and a variety of companies compete to provide service to customers. Separating these concerns means cheap, reliable electricity. Power is quickly restored after natural disasters and we don't have brownouts during the summer. Electricity is affordable and we don't pay extra during peak hours.

I pay $0.10/kWh for a plan 100% provided by wind power. When power is in demand, the smart meter my electric company provided for free (with free installation) will adjust my thermostat and give me a credit on my bill (under a program I opted into).

If my state made me pay $0.40/kWh for unreliable energy, I'd be furious.
Sorry, you’ve got some things wrong about 1Password.

Yes, they provide a cloud option where you can store your passwords on their server for synchronization purposes. But you don’t have to use it. You could just not use synchronization at all, or use a file stored on Dropbox, or iCloud, or other cloud provider of your choice. And if you use only a local file, you can still choose to sync that over the local network with approved clients of your choice with their built in network sync server.

The 1Password authors have been pretty open about how distributed their team is, and how no one single government would be able to convince them to do those kinds of things — the other developers would find out and then the game would be over.

They are also open about the crypto algorithms they use.

As for KeePass or KeePassX, which version do you use? Which of the dozens and dozens of different implementations do you use? Which database format do they support? Do you build the binaries yourself with trusted compilers? Where do you get those trusted compilers and how can you be sure that they haven’t been compromised?
Which part was not correct? macOS does indeed have, and has long had, a keychain API, if that’s the part you’re thinking of.
We can talk about acceptable nuclear waste production right now. Reprocessing on one level has been commercialized for a long time [1]. Furthermore, geologic storage in a repository is ready to go and under construction [2]. Nuclear waste is a technically solved problem. You can get all your energy for your entire life (transportation, electricity, heat, everything) and the waste from conventional nukes would fit in 1.5 soda cans. Nasty stuff but easy to store safety. Nuclear reactors are probably the only energy source that can track the entirety of the toxic waste because the energy density is 2 million times the 2nd best.

Compared to fossil fuels, nuclear energy is a major life-saver, having already offset 1.8 million deaths that would have occurred had the nuclear fleet not been operational [3]. As far as I'm aware, zero or close to zero people have ever even been injured from stored commercial nuclear waste. Right? So why can't we talk about it now while hundreds of thousands are dying early right now from upper respiratory disease from fossil emissions?

Excellent comment. Returned after some hours to check if some other people followed your thread and I felt the need to give you this simple feedback.

Feelings/Emotions are a neglected part of our western culture.
I also think the autoimmune system contributes largely to the overall system. To understand the autoimmune system is to do things like “beat” cancer, aids, possibly some brain disorders, and so on. I personally suspect even life extension could be affected with a full understanding- ie maybe we’d be able to genetically engineer an organism that would repair our telomeres or clean our brains of damage as a symbiosis. It sounds crazy, but I got the idea after hearing about fungi providing nutrients to tree roots in a symbiotic relationship. But first we’d have to find a way for our immune systems to allow it.

Is there any authoritative source on nightshades and inflammation/digestive issues?

After extensive testing, I believe they cause serious issues for me (fatigue, bowel issues, etc)

But when I search for info, I just find sites from sort of woo-woo sources. (Chiropractors, naturopaths, etc)

I'd like to read something more definitive. Both for my own purposes, and also to point people to, as the category itself makes people skeptical.

Spicy food, sure, people get that. But potatoes? That's a weird one for most.
Haha, ok granted. But by that reasoning, can't all problems be solved with more money, at which point there's no point discussing other ways to solve problems? That seems to reduce the argument to be less interesting in my mind.
I don't think that's what they're suggesting. This is more about replacing most register references within opcodes with stack pointer offsets, for faster context switching. It only replaces the register-spilling part of a context switch, along with the register-allocation code in a compiler.

It sounds a bit like SPARC, but more flexible? And not particularly difficult to port to.
True but the photon and graviton both transmit fields. For a black hole to pull matter in it must push out gravitons. Unless there really is no graviton particle and the Higgs tells space which way to curve. Ie gravity is an emergent property instead of a force.
For what it’s worth, assuming an alphabet of 72 characters (52 letters, 10 digits, 10 symbols), this is ridiculously higher entropy than a 128-bit encryption key.

There is no absolutely no need for your password to be this long. Even just twenty characters is within spitting distance of 2^128.
But Windows itself does this when you hover over a taskbar entry, right? Explorer is never that heavy for me.

Or is the process totally different?
I've been pretty happy with Orgzly on Android, but that's probably because I don't want that much from it. I don't really like typing more than a sentence or two at a time on a phone, so I never expected to do any serious editing of Org mode files on a phone. What I do want, and feel Orgzly adequately provides, is the ability to read my Org files, mark things as DONE or put check marks in checklists, and capture one sentence notes that I later fill out and refile, once I'm sitting in front of a real keyboard.

Energy wise, nothing is cheap, which is why I was quite surprised that Fuji Film weren't already moving over to renewables. Japan basically has no other energy resources. Natural gas, oil, coal, uranium: basically whatever small supply they had is already gone. I suspect the reason for factories using natural gas is because it is on demand and the capital cost for the generators is relatively small. Probably long term Japan will use geothermal for baseload, but a lot depends on how the recent test plants perform and especially how they are perceived by the public.
If you reject free markets, contracts, and the social harmony of pricing mechanisms, you had better have better arguments than clicking on a down arrow.
>Why would they bother optimizing?

Because they're also targeting Android devices.
Do you have a source for that Bobby Fischer anecdote? I’ve read several biographies, and I’ve never heard it mentioned that he had trouble memorizing openings. There were, however, quite a few stories that suggest he had perfect recall.
That depends entirely on the product and market, though there are a few general uses. Generally speaking, find the people who are very passionate and vocal about topics your product addresses.

Now, you know two things: the types of words they use, and with a bit of digging, the sentiment typically associated with those words. This can influence your marketing copy and promotions.

Repeat with a few demographics to identify associated areas of passion. Now, you have a group of very passionate people, and maybe even a loose network. Dig in and see if you can find more common associations to tighten the network up a bit.

From there, you could run a targeted campaign- say, a contest with freebies awarded to a number of people who retweet a certain message or hash tag.

People who are tangentially interested hear about your product. People who would have heard about it anyway (by virtue of being in your target market) will now be talking about your product, using your specifically chosen wording.

For the cost of a few freebies, you now have reached your target audience- and thousands more, if they have a significant following. Further, you're not spamming airwaves, or cold emailing, or running ads that are blocked or ignored anyway.

Take all of this with a hefty dose of salt. I'm an engineer, not a sales person or marketer. I'm not on Twitter or Facebook or any other network, so I don't really know all the ins and outs of how to use the product itself, only how to build things those people found useful.

EDIT: for what it's worth, you can do all of this by hand. Doing it well, doing it right, is harder. I won't recommend anyone specifically, but if you're interested in marketing this way, I'd suggest finding someone who already knows how to calculate influence very well and using their services. Otherwise, you'll spend a lot of time on a pointless goose chase, because there is a LOT of noise to sift through to find a good signal, so to speak.
The OS should use all available RAM it practically can for things like cache.

I agree with you on this one, KeePass is way to go compared to relying on browser's password manager.

Haruki Murakami: The Running Novelist (2008)
Your point is reasonable as stated for sure. I'd like to add to the conversation that there's a used fuel repository facility in Finland that's under construction now and is very likely to be the first permanent solution for nuclear waste [1]. The geologists I've talked to are very confident that deep geologic storage is a solid technical solution.

I'd also like to point out that the magnitude of nuclear waste is extremely small, due to the unbelievably energy density of nuclear fuel (2 million times more energy per mass than chemical energy). All the waste ever generated in the US fits in a football field a few stories high. It's incredibly small, albeit dangerous stuff. But that means it's even more reasonable to think we can bury it responsibly, without kicking the can.

There's also been good storage of waste in salt deposits down at WIPP [2]. We know that water moves centimeters in there in hundreds of thousands of years, so the radioisotopes will be well contained outside the biosphere until well after they've decayed to harmlessness.

I'd also plead with you to advocate nuclear energy in addition to renewables and battery storage. We need them all. You obviously are aware that batteries and vast fields of solar and wind and hydro have land/waste/cost/and carbon footprints of their own. I beg you to fairly compare those footprints with the footprints of nuclear energy. Nukes and the intermittent renewables must be partners in our major quest to decarbonize.

Future generations will be much happier with us if we stop emitting carbon than if we safely bury tiny amounts of radioactive waste.

For what it's worth, I disagree with lima. I love them.

Congrats on the launch by the way! Much needed product.
Reminds me of this, https://medium.com/@timgasser/build-a-16-core-128gb-server-f... Looks like from supply and demand those prices increased a bit.
It wasn’t costly. They weren’t going to reuse that core anyway. They’re just starting to roll out their “block 5” cores designed for long-term reusabity, and they won’t fly the older ones much longer. Landing it was just practice for the future.
