Mourou's Nobel lecture [1] has brief explanation of the envisioned process. The idea is to use intense laser pulses to accelerate deuterium ions into a tritium target. The deuterium-tritium fusion then generates high-energy neutrons that can transmutate nuclei.

This is probably not impossible, but I have doubts if this could be implemented efficiently at scale.

I'm a big fan of charter cities/SEZs and new city/country projects but I'm more skeptical this is a practical avenue for making money. There are plenty of established jurisdictions to do this (e.g. basically all the former British colonies, a few American states) and the 'infrastructure' of lawyers, accountants, etc. who know how to deal with it are already established. This is the same reason I don't get why people are bullish on e-Residency for Honduras, Liberland, etc. What's the real value prop of incorporating an entity in these places?

My dad’s dad hit him with a belt when he misbehaved.

My dad spanked me with his hand when I was a toddler. Not overly hard, and not after age 4, but still.

Do I think my dad could have made better parenting choices? Yes. Am I happy that he made substantial advances from what he learned as a kid? Also yes.

A small number of parents are legitimately abusive and should have their kids taken away. Some parents are amazing and talented care givers. Most are just muddling through and fall somewhere in between.

As a parent I am doing my best to keep raising the bar - no corporal punishment over here! But I am sure my children will still find myriad ways in which I have failed them as a parent. Kids don’t come with a manual, and “professional advice” is astoundingly inconsistent/conflicting. I think most parents are doing their best, it is just a hard and poorly understood problem.
> Is there enough demand for engineers that companies are willing to pay for one learning “it” on the go? If yes, what field is it? Trying to avoid cruft and mundane tasks:

I hope this doesn't sound overly harsh, but personally speaking, I'd say this might be a case of the proverbial "beggar wanting to be a chooser". Everybody wants to avoid dumb busywork that grinds you down, and you want to do so while being paid to learn it on the fly. Not saying it's impossible to get, but there's a lot more experienced engineers than you that are going after the fun/interesting jobs that don't have as much dumb work.

> wind and solar just can’t seem to produce enough energy

"They are not producing enough energy, therefore they can't produce enough energy." This is an obviously wrong argument, since there is nothing preventing vast expansion of renewable capacity. The world is constantly hit by 100,000 terawatts of sunlight; total world primary energy consumption is 18 TW.

> Nuclear seems to be the only non-carbon source of power we have today that is actually capable of generating electricity in the amounts our society needs.

This is simply false.
Yes. One point I make about virtual worlds is that space keeps everything from being in the same place. The annoyance radius of jerks is limited. In Second Life, it's about 100 meters, and the world is the size of Los Angeles. There's no "retweeting" or "following" or "broadcasting" to amplify jerks. So jerks are a very local problem.
As a rule of thumb, greenhouse gas emissions are roughly equally split between electricity production, transportation, heating, agriculture and industry, about 20% each. Transportation is electrifying rather quickly in Europe, heating at a bit slower pace. So it's a bit better than "10% of the problem" - it's about 20% now, becoming ~40% in 10-15 years, eventually lowering total emissions by ~60% probably some time around 2050

Agriculture and industry are tough nuts to crack. With electricity, transport and heating, it's a problem of scaling out. With agriculture and industry - we don't even have a blueprint yet

Your numbers appear to be way off. Commercial reactor grade Uranium is enriched to less than 20% (typically about 5%) while weapons grade Uranium is closer to 90% (the first U-235 bomb was enriched to 80%). Some specialized reactors do use highly enriched Uranium however.

I'm sure OP is getting lots of comments now! I'm not sure the rapid timing is really the cuprit here. I would argue that there are other UI factors at play:

* The text doesn't get cleared from the comment box after the comment is sent

* The submit button has no visual affordances to indicate whether it is valid. It looks exactly the same when the form is populated or empty. A conventional UI approach would inactivate the submit button until all the fields are filled.

So despite the message that the comment has been posted, it doesn't appear as if the state has changed as a result of pushing the button.

I think clearing the comment box and inactivating the submit button (which doesn't appear to be a native OS UI element) after submission would help users understand that the state has changed. Alternatively, I think displaying the acknowledgement message on a new page with no submission form would achieve something similar. It could even have a "post another comment" link back to an empty comment page.

Google controls JS to the point of being able to ignore the spec (e.g. that time they left TCO behind an experimental flag and it just went away despite being in the spec).

As long as node and chrome are so dominant, we're probably not going to see big shake-ups in JS that aren't driven by Google themselves.

JS is flexible, you can cover up a lot with polyfills, but not completely different syntax. Doing that without Google's buy in would create a rift in the internet that would either end with browser specific web pages, or with the complete loss of power for the committee that sets the ECMAScript spec as JS officially goes from being a language that is defined by a spec to a language defined by a canonical implementation (in this case V8).

Less radioactive waste than coal power plants, and significant less devastation compared to continuing funding wars by buying gas, oil and coal.

Energy generation is always a trade off. Right now the world is reacting to the fossil fuel funded wars created by one such trade off. We are also in the middle of causing irreversible climate change, which would cause more damage than any amount of meltdowns or nuclear waste could ever get near.

Naturally there are alternatives. If money were no objection then green hydrogen looks pretty nice, and one could always extract heat from the core of the earth as long the technology was safe enough to do so. As soon we have a technology that get proven to be cheaper, safer and more scalable than nuclear we should all switch to that. Buying natural gas from Russia is for multiple obvious reason not that.

While I was a graduate student at UT Austin, I attended a talk By Dr. C.P.J. Barty, Chief Technology Officer for the National Ignition Facility and Photon Science Directorate at the Lawrence Livermore National Laboratory, titled “Extreme Gamma-ray Sources and the Dawn of Nuclear Photonics”. It was quite fascinating. The basic idea is to use a linear accelerator to accelerate packets of electrons to relativistic speeds, and then to interact those packets with an infrared laser pulse (inside the laser cavity), to generate tunable extreme Gamma-ray laser pulses. They were able to demonstrate burning of nuclear waste products, as well as distinguishing between different elemental isotopes based on their absorption.

I haven't heard anything about the project since, but it sounded like a promising approach for burning nuclear waste, particularly when using a superconducting accelerator to do energy recycling.

i wonder how much have you contributed to humanity to consider your self "over".
If the biggest externality is heated water in a subarctic climate, or nuclear waste that gets stored on-site indefinitely in casks and produces no notable leaks or accidents (like has been done in the US for a long time now), the externalities are way less than literally any other form of energy production. That includes Dams, solar power, geothermal, wind, you name it.
No, quite the opposite. Bombs and reactors use fissile materials with long half lifes, i.e. 235U (700 million years) and 239Pu (24 thousand years). Isotopes with short half lifes are very difficult to handle since they produce a lot of heat and emit high levels of dangerous radiation.

I mean it's obviously purely anecdotal, but I would by no means consider myself an audiophile. I use Airpods Max at my desk and Airpods Pros during my run, and that's about it.

I would love to see someone do this experiment though, maybe I am an audiophile and didn't even know it.
It's funny, I've experienced the opposite, usually in the form of the "senior" title being handed out as a retention incentive because the company doesn't _really_ want to pay more. Here's a senior title and a 5k raise sort of thing.

That said, I agree that these requirements sound too specific, but they don't sound too intense. I mean, After working in the industry for ~8 years I would expect someone to at least be familiar with a bunch of this stuff.

I should really make template comments. Being asked to explain why Chernobyl is not a realistic scenario in the 2020s, with all the available information and previous discussions, has been getting really old...

See https://whatisnuclear.com/chernobyl-main.html#again

Or even just another comment in this very thread: https://news.ycombinator.com/item?id=30653778

Or the fact that it hasn't happened despite hundreds of active nuclear power plants around the world (not all in countries that you would expect to have high safety standards).

Or the safety statistics in general: https://ourworldindata.org/safest-sources-of-energy

Same with the waste issue. Nobody asks what the proposed solution is for CO2 storage (it will remain for billions of years! The horror!) when proposing to keep open coal/gas plants a bit longer until we have solar/wind/hydro+storage all set up, but with nuclear we need to find more reasons for the phase-out.

Here's another info page: https://whatisnuclear.com/waste.html

> If these materials are burnt in fuel through recycling, nuclear waste would only remain radioactive for a few hundred years

And that's ignoring that we're also managing to deal with the waste so far just fine, also without recycling.

(The tally is at 40 minutes time wasted for these two answer so far, also because most of the previous one was 'researched' and written on mobile. How long did it take to ask the question? This is why I contemplate templates.)

> The solution for the $5, 45min ride that comes out of the driver's pocket is to guarantee the trip price covers a profit for the driver and let the rider choose if it's worth it. But that would mean fewer trips and lower guaranteed profit for Uber.

IMHO, a $5, 45 min trip should just never happen. Algos should price that properly and drivers should get more transparency so they can choose to not accept bad terms before it ever becomes about cancelations.

If those EVs are mainly charging at night, where does the extra peak load come from? Or is this just a case of not being able to shut off as much NG/Hydro generation at night (since nuclear can’t really be turned on and off at will)?

Wouldn't the simple solution be to guarantee a minimum hourly rate from the time a driver accepts the ride to the drop-off? Uber would have an incentive to be efficient (find closer drivers, get more drivers on the road) and drivers wouldn't worry about the 45min-$5-ride problem. If the ride is profitable on its own, there's no change. If there are no close drivers for a short ride, the ride would (and should) cost more.
The need for flags in itself may be a sign of the wrong approach.
You create a shared module.
But for some cases the handling should be different. Let's pass in a flag or configuration. So somewhere in the shared component it will handle things differently. Oh wait, there's another case. Another flag.
Which combinations of flags are meaningful and which aren't? The nearest improvement is to put all the cases in an enumeration. But wait it's not one 'dimension'. Let's have two enumerations. And the extreme end point is that your shared module has a full blown DSL for the parameters it receives. Or even an interpreter.
The other solution that is often more understandable and debuggable in the long run is to not have the shared module call specific code for cases. But to have specific code pull in shared commonalities. No need for flags.
>The use of the terms "correct" and "incorrect" suggests that there exists a universal ground truth, and my whole point in this discussion is that no such ground truth exists.

The universal ground truth is the intersubjective understanding of language norms.

>The only way to get around this is to establish a specific cultural context where a ground truth can be agreed upon (e.g., a style guide used by a particular publication venue).

Yes, and such context exists. The main prestige dialect in the US is General American, all other dialects are marked geographically, culturally, professionally or in some other similar manner.
The Expanse isn't a "remake" of a decades old comic book storyline, quite a few movies aren't. I like movies that try to fit into an overarching "mythos", but that's just one particular approach to storytelling.

You seem to be equating “mining” with “selling to third parties”, I don’t think it’s the common use (I understand it as “gathering data”).

Also there’s many ways to exploit the purchase data without ever selling it outside the company, including using it in aggregate for ad targeting without exposing specifics to the ad buyer.
If you have datacenters on multiple grids (and applications that are favorable to being moved around), you could direct traffic to where energy was abundant. This is not uncommon for large commercial sites; you can usually get a better rate from the utility if you commit to demand response, and it's not too hard to shift load if you're already doing multi-site for reliability/continuity)
Indeed, we are left with (from my perspective) all bad choices in the short-to-medium term. In the US, we made a least-bad calculation when choosing the environmental cost of fracking over the geopolitical costs of depending on dictator oil. Now Europe gets to make similar calculations.

I'd sure like it if less inherently dangerous technologies were further along. But every year they are gaining.
> Ah. Is that the (sole) strategic goal, or is that a tactical threat - which many people believe useful for "improving" the situation? And perhaps also a feels-good, looks-good bandwagon that lots of people want to jump on at the moment?

Economic collapse in Russia would result in: Putin losing power, Russia losing war or at least retreat from Ukraine. Most likely, multiple bigger civil war started in Russia Federation.

> I'm thinking that most of the grown-up western leaders have a list of actual strategic goals, which looks more like this:
> - No nuclear weapons used, especially not at scale, nor against my country.
> - No nuclear weapons "lost" (to parties unknown) in a chaotic break-up of Russian state authority.

That why West can only help Ukraine indirectly and fight suing economic sanctions.

> - No massive/widespread economic collapses, wars, famine, etc. resulting in very large (say, 1+ million) deaths. Nor (say) 10+ million refugees.
> - No "large, ongoing" failed state situations.

Russia proven that they are European bandits and cannot be trusted. Nobody in EU will care about future of Russia.

> Russian's invasion of Ukraine clearly fails (short- or long-term) in the eyes of most Russian government & military leaders. Ditto most autocratic leaders in other nations, who might be tempted to stage invasions of their own.

You underestimate propaganda efforts. Most Russian still believe in military peace keeping action Donbas. Reality distortion is very strong there, sanctions are helping to get the message across.

> - Ukraine and its people are freed from Russian occupations / attacks / threats, and have a good opportunity to rebuild...preferably not too far in the future.

It is not so clear-cut. Once Belarus joins the war and French and German interest betray Eastern Europe, we can expect half of Ukraine lost and EU failing apart.

> - My, my party's, and my government's situations are improved (or at least not seriously degraded) by events related to Russia's invasion of Ukraine.

Most of Eastern Europe will benefit from the current situation.
