Exhaust from a gas turbine for a pipeline compression station is around 600C at about 95kg/second. That flow contains about 100MW of heat energy, which can be captured with Organic Rankine Cycle (like steam cycle, but using organic fluids like cyclopentane as a working fluid to better match the thermodynamics) about 20% of that can be converted to electricity. This is off-the-shelf tech.

The problem isn't the technology, it is the economics.
Yeah, a better option is to use capital costs and input them into https://model.energy

I recall nuclear being part of Hillary Clinton's presidential platform, and Biden has mentioned it as well, though I'm not sure it's a priority for him. Lobbyists are more an issue than political parties when it comes to energy. Nuclear energy doesn't have a powerful lobbying arm like Big Oil, unless you count the military.

The Human Brain Project is a somewhat failed experiment to understand the brain in its entirety. They started by taking human brain cross sections and imaging them down to neuronal resolution, but the scans took up so much space that there wouldn't be enough capacity on the entire planet to store a complete human brain scan. This is a challenge of compression inasmuch as it is a challenge of understanding brains.

I question if progress in any given field X is completely and unequivocally hindered by progress in a dependent field Y. If this is the case, dependencies better be known up front before embarking on any project, unless you like wasting time and money.
Inside The Square Kilometre Array (2013)
Diffusion and buoyancy are indeed both things about the weather, but the nonlinearity of the navier-stokes equation stems from the ability of convection to transport momentum. Fluids moving through rocks can't go fast enough for that to happen.
It absolutely is a factor for the politics of site decision. I've checked Yucca Mountain; apparently the closest settlement is like 25 kilometers away or so, the next one like 40 kilometers or so. Finding a comparable site in a country 1% the size of US with quadruple the population density and with no sparsely inhabited areas is a Herculean task -- especially if you don't have huge areas appropriated by the military for such purposes.

> Look at the map from the US, many sites of varying level are extremely close to major metropolitan areas. They are often deep underground.

Wikipedia tells me that the Waste Isolation Pilot Plant in Carlsbad, NM is currently the only deep underground waste storage site in the US.
Leaks and emissions specific to NG aside, NG is primarily a byproduct of the oil extraction industry. It lives in a symbiotic relationship with it. To truly get off oil we need to get off gas as well. There's a reason why oil patch boosters and lobbyists and climate change deniers in places like Alberta are also pushing natural gas; the fortunes of oil and gas are tied together. This is a lobby and sector we need to deprecate not support.
I have been disappointed by cross browser discrepancies in the canvas element. Chrome and FF handle Alpha values very differently, and the results are extremely noticeable if you do anything that involves layering many semi-transparent layers on top of each other. There are other floating point rounding error quirks as well, e.g., firefox can translate a context by 0.001px whereas chrome is limited to a precision of only 0.01px. These discrepancies make it impossible to do certain things that look the same on all browsers.

Google is countersuing Epic Games, claims it's owed for lost revenue
I agree, but I think you can't demand-response away all of winter. People still want to drive their EVs and heat their homes and industrial processes can't be time shifted for weeks or even months.

You'll need some storage. Right now that would probably be Hydrogen or Methane, and making those is pretty expensive. Perhaps something better will come along, or it gets cheaper with scale, but at the current CO2 price it's not competitive with fossil fuels.
South Korea hasn't forgotten. They have gotten the costs down quite a bit.
Doubtful. Just think about the toilet paper shortage; a common household item that never would have had a supply shortage if people just maintained their regular buying patterns.

Now think of masks; a non-household item that a small percentage of households carried. Even if people were reasonable and only bought an amount to cover their needs, that would have introduced hundreds of millions of new buyers for that item.
It's much easier to lose trust than it is to earn it. Lie just once and you can wipe out years of hard-won good will.

Isn't it a bit unreasonable to lie but expect people to still trust you as they did before? This is not some new premise that the authorities got blindsided by; Fool me once, shame on you. Fool me twice, shame on me. They should have known better than to lie, no matter the motivation for a lie.
Provisioned concurrency is a bit of a non-starter for cold start latency reduction in user-facing applications. Its a tool in the toolbox, but the problem is: Let's say you set the provisioned concurrency at 10, then you have 11 concurrent requests come in. That 11th request will still get a cold start. PC doesn't scale automatically.

The ping architecture of warming up functions does scale (better) in this setup. Its not perfect, but nothing on lambda is; its possible that the ping request for User2 could get routed to a live function, which finishes, then starts handling a real request for User1, User2's real request comes in but this function is busy, so Lambda cold starts another one.

That being said, these ping functions can be cheap relative to PC. PC is not cheap; its ~$10/mo/gb/function.

With the ping architecture; you'd generally just invoke then immediately exit, so there's very little billed execution time. For sparsely executed functions, the ping architecture is better because PC is billed 24/7/365, whereas ping is billed per invoke (that being said: PC is a much cleaner solution). For high volume functions, PC may be cheaper, but it also won't work as well; if your concurrent executions are pretty stable, then its a great choice, but if its spiky high volume (as most setups are!) then it's hard to find a number which balances both cost and efficacy.

A setup which also includes Application Autoscaling, to automatically adjust the PC level with time of day or system load or whatever, would approach a better setup. But, of course, be more work.

The other frustrating thing about PC is its price relative to a cloudwatch events cron warming setup. Most sources say Lambdas stay warm for ~5 minutes, which means you only need ~15,000 invocations/month per "faux-Provisioned Concurrency" level. Theorycrafting at 100ms/invocation and 512mb: that's ~$0.012/month. PC is ~500 times more expensive than this. This kind of cron-based ping setup is very easy when PC=1; at 1+, it gets harder, but not impossible: You have a cron configured to execute a "proxy" lambda, which then concurrently invokes the real lambda N times depending on what level of PC you more-or-less want.

It's also worth noting that PC cannot be maintained on the $LATEST function version. It can only be maintained on an explicit Function Version or Alias (which does not point to $LATEST). So there's just more management overhead there; you can't just have a CI deploy functions and let AWS do everything else, you have to configure the CI to publish new versions, delete the existing PC config, and create a new PC config, maybe also adjust autoscaling settings as well if you configured it. All automatable, but definitely in the domain of "CloudOps Engineer Job Security"; anyone who tells you AWS will make your life easier is probably working for AWS.
Why is there no money to be made? I would at least pay to buy the hardware and possibly for ongoing software support as well (depending on how they structure such support or any other "soft" features). E.g. I think its a jolly good idea if somebody really checked for a living all those open source apps.

In any case if there is really no viable business model for private mainstream mobile computing we have been duped big time: This is not a consumer device, it is track-and-trace machinery.

Can you point me to some? How were they caught? I knew this was a possibility, but I hadn't seen it actually happen before.
In the US, natural gas produces more emissions now than coal, if you include heating. NG is now the big fish to fry.
Same. It feels like the "have the cake and eat it" situation for me who switched over from iOS.

I was worried that some apps might not work but that is not the case. Everything from banking apps to password managers just works fine with the only exception being NPR One (which is hilarious).

They are really doing an outstanding job and I do not miss anything on here besides a Apple/Google Pay NFC solution. But that is quite ok.
"But nuclear is reliable and doesn't need this "natural gas assist". Even if a hurricane sweeps over an area, the nuclear power plants will keep working."

Actually, they don't.

"As a precaution measure, the reactor shall be shut down at least two hours before the hurricane’s strong winds arrive at the location. Generally this happens when the speed reaches between 70 and 75 mph (between 113 and 121 km/h)." (https://www.foronuclear.org/en/nuclear-power/questions-and-a...)

Also, they need electrical power to keep the reactor cool---typically the power grid and co-located diesel generators, not necessarily the best redundant backup system.

Anecdotally, I've evolved in to a flexitarian (first I've heard that term is this article) since I met my partner who's a vegan. As a result, I eat many vegan meals, both at restaurants and prepared at home. When I eat vegan, I generally avoid plant based "meats", partly because I don't really know what's in them, partly because they are inevitably highly processed, and partly because if I'm eating vegan it's because I don't want to eat meat, so why would I eat something that goes out of its way to be like meat.
Most EVs have enough battery to cover more than a week of daily commute. If you could charge for significantly cheaper and greener than you do right now, by simply telling it to only charge when the panels on the roof are producing a surplus, isn't that sort of a no-brainer?

Maybe you'd go back to grid mode when anticipating a weekend trip, or when the charge hits some sort of level of concern. And I expect polar places with cloudy winters would probably run a fair bit of conventional generation like we do now, in the winter. But during the sunny season, shut it down!
At the rate panel prices are dropping, they'll be cheap enough it won't matter. But, while I'd prefer them on homes, I think most solar will go to big, commercial solar fields.
Monads are chainable containers for a computation. The container represents some sort of "effect" implicit to the computation ie asyncrony, optionality etc. This is not technically 'correct', monad explanations are always a bit cursed, but I find this a pretty useful intuition to work with day to day.
It's near a place where that amount is just a drop in a bucket.
Agreed. Not the stuff of action movies, but welfare checks, coordinating with the community what resources are available, where they are, and what times they are available. Think food, water, etc. But if the rescue workers can accommodate helping a smaller percentage of the population hams can help identify folks in dire need.

Digital modes, winmail and similar have been heavily used for getting medication to those in need, mostly because some meds need refrigeration and the power grid doesn't have to be down for long for everything refrigerated to go bad.

I’d just choose some small subset of your dataset as a sample dataset, expose just that, and accept that some users will scrape and make use of that.

If this really isn’t satisfactory, the best you can do is non-interactive video, I think.

For your actual paying customers, you control it via contract rather than DRM.

>consequences of no longer having trustworthy institutions.

Those institutions just spent years getting called deep state by half the country, systemically racist by the other half and in the pockets of entrenched and moneyed interests by both. Color me shocked that nobody trusts them.

The same people who were so happy a year and change ago to earn cheap internet virtue points trotting out tropes about about how the noble FAA has been neutered by Boeing and the revolving door are complaining that people don't trust the CDC. You can't have your cake and eat it too.

This is a feedback loop. The lower the expectations from these institutions (government, academia, etc.) the less they have to lose by behaving poorly and the more they will behave poorly. It will get worse until it gets so bad it starts getting better.
The word "could" is doing a lot of work, there.

but that's my point. knowing how to compile a program does not make me a compiler engineer. in that sense feel free to use ML tools, but don't be fooled into thinking you will get a job as an ML engineer if you do not know what the chain rule is, or why we need to take a derivative in order to optimise a loss function. in fact, don't even be fooled into thinking you will get into a ML uni degree if you don't know what the chain rule is. i actually don't understand what is the problem. spend 10 minutes reading up on it and i am sure you will get it. i think an unwarranted phobia of mathematics is what is at play here
> But, because Rust's traits have semantics not just syntax the actual effect is different.

Don't concepts give C++ the same semantic power? What am I missing? Concepts give C++ generic code exactly the same nominative constraints you're describing, yes?

Besides: even without concepts, you can use tag types and traits to similar effect. Not everything needs to be duck-typed, even in C++17!

One of my main problems with using Rust instead of C++ is losing metaprogramming power. I really like the template system.

While I see where you're coming from, semantic formulation like this is highly subjective. All the same the problem statement could be "Given any kind of input, tell me whether it's a Human or not".
Sometimes I feel crazy when people start arguing about nuclear. Up here in Ontario, 60% of our power comes from nuclear. If Canada can manage to have an indigenous nuclear industry with our culture of regulations and red-tape, what on earth is stopping an economic powerhouse like the EU.
What does a coal plant do with the emitted radiation, CO2, coal ash, and other waste products? Current spent fuel rods from nuclear reactors sit in concrete casks located on site usually. At least I don't need to breath spent nuclear fuel or have to deal with it's CO2. Not saying we should do nothing about it, but at least the impact to my life today is substantially less.
If you feel that way, you should upvote posts you find more interesting.
I'm starting to think pushing more decisions to the state level is the only way to cool things off in the U.S. Rather than having these life or death battles for control of the federal government, letting people eventually self-sort into states that align with their values may be a more workable path forward. It's not perfect, but it's better than what's going on now and what the current situation could eventually escalate to.

Don't confuse popularity with hotness. The latter is the first derivative of the former. Rust is hot, but not popular. Scala is somewhat hot (was truly hot a couple years ago) and somewhat popular. Java is lame, but very popular. JavaScript is... a goddamn black hole.
I wish I couldn't say "see ?" but it rings with my experience too much.

It seems to me that our society all revolves around an absurd pressure for housing~.

If you give a roof, clean water and some veggies to people, .. expect a solid 5x increase on every metric. When you stop playing shitty politic games, surprisingly people have more energy.

But since people are under threat they accept what the market offers and we're in this sad pool of misery.

UBI might never work but after my little volunteering and others [0] I was under the impression that we need a device of this kind to free people.

It’s actually frozen deuterium tritium. Inside a small pellet blasted by X-rays which compress the pellet until it’s hot and dense enough for the fusion energy produced to continue burning and heating the deuterium/tritium until much more energy is produced than the energy of the X-rays.

It all happens in an instant. The pellet’s structure doesn’t survive. But it happens fast enough that just the inertia of the pellet (turning to a gas and then a plasma) keeps things confined for long to fuse a significant amount of the deuterium/tritium.
Nuclear waste is a mostly artificial problem considering we've known how to recycle/reuse nuclear waste to the point where it is no longer dangerous. The actual hurdle to nuclear adoption is really more about concerns with nuclear proliferation since a lot of the recycle tech can also be adapted to create weapons grade nuclear fuel.

Additionally, even with no nuclear reactors whatsoever, we'll still have to deal with nuclear waste as it is used in various other areas like medicine. The Goiânia accident incident in Brazil killed many people _immediately_ (unlike Fukushima) and originated from a defunct hospital, not a nuclear power plant. We need to find ways to deal with this stuff regardless if you use nuclear power or not.
The unpopular truth is that fossil fuels are far too cheap. If the negative externalities were priced in, they would be at least twice as expensive, perhaps as much as ten times.
