> Given the climate crisis, the government should be doing the same as they did with the CRS for space, award DOE contracts of $X billion for a working reactor, dole it out to people doing SPARC or Thorium Molten Salt (LIFTR) designs.

> The innovation rate in Fusion is way too slow, we need to build and fail a lot more rather than sink $22 billion into multi-decade projects like ITER.

We don't need fusion for climate change; fission will do, and we have working reactor designs already. I don't mean that we shouldn't spend some money on fusion research, just that it isn't reasonable to spend 100% GDP on it (or some significant fraction thereof).
The scenario you describe sounds plausible to me.

Yeah, I do feel for those that come late to a trend, but can't shake the short-term mentality. I got big into TSLA in March, at the very last moment before it exploded upward. I'll move back into my parent's basement before I let those go...
>> The innovation rate in Fusion is way too slow...

I'm starting to think real progress on fusion is suppressed because there might be a risk lurking there.

This isn't true. Shootings are very, very rare. And they are concentrated in certain types of places (e.g., poor urban ghetto) such that the parts of the country that aren't these places have vanishingly small probabilities of being hurt by a shooting.

Gun murders in the U.S. are a very low percentage of deaths (0.39%) and preventable deaths (~1.1%, there's some disagreement about what's "preventable"). That's 0.0036% of the population per year gun-murdered. That this statistic is 3x some other country's is irrelevant because 3x a small number is still a small number. If your goal is to prevent untimely deaths, focus on boring things like falls, car accidents, and diabetes.
I have device with me and on full load on both CPU and GPU it can go up to 25 but for most use cases i see the whole SOC hovering around 15W
> We appear to be at the tail end of the maximum hype part of the boom-bust cycle. Thinking that the rapid gains being made by the current deep learning approaches will soon hit a wall is a reasonable outside-view prediction to make: nearly every time we've had a similarly transformative technology in the AI space and elsewhere, hitting the wall is exactly what happened. The onus would be on practitioners to show that this time really is different.

What a take. Neural networks just took a huge bite out of protein folding and your take is: This just in, the Deep Learning boom is about to go bust! Asinine.
I think it would be much more usable as a electronic signage display, however, rather than interactive... Or if you needed to manipulate anything in detail in the GUI, it would be less awkward to do it over VNC.
> Contrast this with a hypothetical cpu that has only one register "base" and allows to address 32 words after the address at that base register.

This, er, wasn't really hypothetical. The TMS9900, the CPU used in the TI-99/4A, had three hardware registers: a program counter, a status word, and what was called a Workspace Pointer (WP). General purpose "registers" lived in RAM, and were referenced by an offset off the value in the WP. Subroutine calls were initiated by saving the PC and changing the WP to a fresh new register context before branching.
Interesting. I thought overlay2 can be agnostic to the base filesystems.
True. I'm old and I just have no desires anymore to spend money on. Low appetite, low libido and low energy, tired of traveling ... wish I had 1/100 of that money when I was young.

False equivalency. Hospitals don't overflow with flu patients every winter. Meanwhile just in Italy and NY, hospitals were overflowing with Covid patients with only a fraction of people exposed to it compared to the billions exposed to the flu every year.

Same with the number of deaths. 65,000 in a really bad flu season in the US with hundreds of millions exposed to it, and Covid already has exceed that with only about 20% exposed to the virus.
Regarding #2 and #3, I don't think there is a way to speed this up. The only way they are testing these vaccines is by looking at the percentage of people who get infected who either got the vaccine or placebo. One of the reasons that these vaccines have been able to be produced so fast is that COVID is rampant, especially in the US, making it much quicker to hit the N-number of cases necessary to test.

There was talk early on about doing "challenge trials", where'd they vaccine a sub-group and the purposely infect them with the virus. There are huge ethical issues with this, especially for a virus with which we don't clearly know if someone will range from asymptotic to death. We certainly have statistics on likelihood, but there have been many reports of perfectly healthy, young, people dying from the disease. Given that unknown, I don't think it's possible for anyone to give informed consent for this kind of trial.

Could this be weaponized in the way nuclear energy can be weaponized?
I think it follows a general theme where some people have a "tricks"-based mindset. Some people look at Tesla and think it's just tricks. Such as the idea that people are buying Teslas because of the drivetrain - which would be a simple trick, rather than the reality that Teslas are just all-around great cars - something much harder to understand.

The Nikola founder probably thought Musk had succeeded in unlocking a series of successful tricks, and set out to reproduce them. But when you don't know the reason for the formula, you don't know what steps you can leave in or out, so you just follow it mechanically.
Certainly the first two are not trustworthy and are sometimes dangerously wrong.

Mayo’s advice is not bad but I think the government (CDC) is better ground truth, especially for public health issues like ringworm.
Why do you think a 5 year timeline is too long for the challenge? AFAIK most people think that is way too ambitious.

Spacex took 6 years to get into orbit (and were not the first by decades) and you think they could show energy gain fusion in 5?
Think of it just like fire. Fire will also give you almost no energy if you physically scoop it up. Instead you leave the fire where it is, continually generating heat, and you capture what pours off. Or you pump in fuel, ignite it, and exhaust it over and over at a high speed, like in an engine.
But surely the whole point of this is to eventually create a lot of steam, right? So hopefully it will have enough energy to do that.
It seems like Apple walked away from a bad PowerPC situation into Intel's arms only until they could do something like this... Especially after the past few years where Intel can't execute on the fab process and forced Apple to switch vendors when Intel couldn't execute on 5g.

As far as I understand there is a nuclear waste problem, since neutrons are generated which activate the hull significantly. Neutron cannot be deflected.

But I dont believe this is the show stopper why progress is slow. To me it feels more like people know ther e is a technical insurmountable problem ahead (like how to efficiently enough transform the energy to electricity; actually really wondering how this should be scalable) and people involved do not want to reach that point.
What conceivable risk could there be that supports this hypothesis?
None of these problems are problems in elixir or zig, the two langs I'm most familiar with currently (they are handled differently, of course).

> reddit is where I go to get on the ground crowdsourced recommendations

I would be careful about this on reddit. Subreddit communities are heavily influenced by fotm, everyone repeating the same thing(there's a word for this and i cant think of it...) Dissenting opinions to what ever is main stream gets downvoted. Reddit communities are also heavy on beginners. Those beginners often don't realize how much depth of knowledge they are missing.

It might be a place to bounce ideas off, but I would only go there after doing some of my own research. It should only be one tool of many.

In areas I consider myself knowledgeable, I see terrible advice given out. Often parroted by beginners. Like people in the headphone subreddit can give recommendations without listening to them. cscareerquestions is the blind leading the blind more often then not. There's no way to differentiate experience with someone fishing for upvotes or think they're being helpful by repeating someone else's advice.

I also think there's some astroturfing going on sometimes
Basically humans have an instinct for graffiti, a few standard interests (hands, sexual anatomy, prey animals), and there are a few material combinations that survive the ages particularly well.

I don’t think we can assume the errors are normally distributed. It’s possible researchers are biased in a particular “direction”, away from 0 on all dimensions of this problem.

I find an interesting related item to be the ~30% of people in the AZD1222 (AstraZeneca) study who got COVID after being vaccinated. They reported that in this subgroup, there were no severe infections, nor any hospital visits, confirming the parent's hypothesis that some people might not get full immunity, but still benefit from the vaccine.
Wanted to open it up to others’ ideas first.

It’d need to appeal to a younger crowd, not just families. So it would need to have bars/restaurants/other cultural destinations.

Since almost no one needs to commute, it wouldn’t be designed around the car and driving. So would need some mechanism for people to receive deliveries and go get other goods from local stores without having to get in a vehicle.

I think it would be a good idea for there to be communal kitchens and dining halls. I’m thinking most people would want to get food delivered or sit out in a public space for lunch, but would get together with other households and cook for dinner. Large dining halls would be great for frequent festivals and celebrations.
I've found myself in situation as well.

I feel that the "produced excellent results" has a lot of unpack there.

It obviously wasn't scoring 90+ in CASP.

Actually, after reading your linked blog post, it's pretty obvious why they weren't exactly chomping on the bit:

"To gain insights into the receptor’s dynamics, Kai performed detailed molecular simulations using hundreds of millions of core hours on Google’s infrastructure, generating hundreds of terabytes of valuable molecular dynamics data."

Hmm, yes, hundreds of millions of hours of cpu time, hundreds of terabytes of data, who says no to that? It doesn't even seem seem to attack generalized protein folding in general. It really seems like the plan was, "let's attack this problem with a Google-sized firehose" rather than created a fundamentally different algorithm that had game-changing results.

Comparing your system to AlphaFold seems like your really bending the truth here.
Complaints I've heard: json broken, no good way to do orm, http library not great, no good framework for http webserver, etc. Channels/goroutines are deceptively hard, easy to cause resource leaks.
What is actually the plan to harvest the energy (how to get the heat to a steam engine or whatever and generate electricity?)
The question is if we would have any innovation in fusion without ITER. It is a research installation meant to prove fusion is viable for generating energy. It's basically designed to be surpassed by later designs.

But it's also like an Apollo program for fusion installations. It doesn't have to be economical, it just has to work.

What I find interesting about this explanation is that it suggests a much more limited scope of decision-making than is often attributed to humans. A practical example of why this could matter is that instead of spreading an idea through viral mechanisms where an information is transmitted between individuals, this would provide an illustration of how an idea could be spread by replicating conditions and causing the idea to essentially regenerate in a predictable manner among disconnected individuals, while from each individual’s perspective they are doing something novel.

Got a BS/MS in CompSci in my twenties when I was immature as a person, now doing online classes for a non-tech major. As an "adult student" the system seems 10x more broken than it was when I was a high school graduate.

Being young and tuition-free it was easy to grind through the material just worrying about the next test in the next class. Now, here I am as a tricenarian trying to relax and understand hundreds of pages of anatomy material while everyone else seems to just binge seems so asinine. After 75 pages of reading, exams continue to be a black box. Here I am paying for instruction and the professors can't be bothered to tell me what's important to know for the career let alone the test.

I got one teacher to chat off the record and he basically said to "get through it." What a disservice to students. Why are there still weeding-out classes? How many doctors, surgeons, programmers, engineers would there be in the world if it wasn't for these classes? The Montessori education system and the like seem so superior. College should be pass/fail.
They weren't the first to build a new engine or an engine of that type or land upright. They just combined previous achievements in a better way. Their technology is incredible but it is all incremental improvements combined with a sustainable business model.

There is little energy stored in the gas, but it produces lots of energy. I.e., every second the gas might produce a megawatt second of energy, but only have the heat capacity to store 1 kilowatt second. Numbers may not be to scale but you get the idea. I'm also not sure how this stays stable. I guess that if the gas gets hotter the process breaks down? Mayb the volume expands within the confinement and the reaction rate goes down as a result?
