Yes, it is. I'm not sure what you think that post says, but it means LavaRand is currently serving a purpose in production. The whole point is to add more randomness to their other methods to protect against exploits or failures in the implementation of those methods. This is like the drives in a RAID setup. All those drives are a waste of power if you only care about when things work right. The point is to provide safety when things break.

The previous paragraph:

>> "LavaRand is a system that uses lava lamps as a secondary source of randomness for our production servers. A wall of lava lamps in the lobby of our San Francisco office provides an unpredictable input to a camera aimed at the wall. A video feed from the camera is fed into a CSPRNG, and that CSPRNG provides a stream of random values that can be used as an extra source of randomness by our production servers. Since the flow of the “lava” in a lava lamp is very unpredictable,1 “measuring” the lamps by taking footage of them is a good way to obtain unpredictable randomness. Computers store images as very large numbers, so we can use them as the input to a CSPRNG just like any other number."
Yo, chill with the assumptions. Nothing about this article/discussion has to do with your comment.

Fuck natural gas. Just because coal and oil are terrible doesn't mean that it is a good option too.

Build hydro, build nuclear, build wind and solar if you have money to waste. But natural gas is not a good stopgap measure while we get to fusion.
Correct. It is more of a demonstration of the scale of the pandemic, that it has taken years off the collective population’s life expectance, in the same way that infant mortality does in developing countries and the US.

Maybe you really believe this, but to me it comes across as gas lighting. I know what I remember, all the blabbing heads on the media were telling us to stop buying masks because they won't help us. Maybe you earnestly believe otherwise, but I think this line of argumentation will never be accepted by the vax-avoident. On the contrary, it probably contributes to their perception that they are still being lied to, and consequently, will only strengthen their resolve.

Nuclear fusion requires both compression and heating of the fuel. In nuclear weapons, this is accomplished with a combination of radiation pressure and a fissile sparkplug, respectively. In inertial confinement fusion, there are two distinct laser pulses with different characteristics. A fusion pellet detonating would release radiation that could compress another pellet, but there would be no method of heating that pellet at the appropriate moment.

There may be an engineering method to overcome this, but it would be way beyond the difficulty of getting that first pellet to ignite, which already is a bleeding edge technological development.

Re "While this was true even 10 years ago..."

A very remarkable thing is the decline in the cost of renewables just in the last 10 years.

The cost number have completely flipped in that time, not even counting the cost risk from delays, underestimated decommissioning costs for nuclear, the uninsurability of decommissioning costs, and the uninsurability of of nuclear accident risk. Solar and wind are cheapest now, by a multiple.
So... Are those listed in order of importance?
Although it is an poll with a weird and surprising result from a nuclear lobby group with a strong interest in depicting the general public as "in need of education" on nuclear issues.

As far as I can see there are no details about who ran the poll.

"Finland lobbied EU to declare nuclear power sustainable"

Well, isn't it? Am I missing something or is nuclear about as sustainable as it gets? The perfect baseload to cover us when solar or wind is out. Almost no CO2 produced, much lower deaths/GWh produced, plentiful fuel supplies?
I think this is a real testament to factors of safety. In construction, you need something to hold 150 lbs, then it need to be designed to hold 1000 lbs. Prob the same for these penetration performance ratings.

Yep, nukes require cooling, and good cooling mean either the seashore or a large river with suitable sites. Hence there being 4 plants on both Rhone (highest discharge in the country, not including the Rhine) and Loire (longest river in the country), while the smaller Garonne rates only 2.

That discussion makes the baseless assumption that the simulating world must resemble the laws of physics of our simulated world. Under such constraints the theory could be testable, but the idea behind it will always be able to retreat to other constraints on the simulating world.

Similarly, if we assume that God must have certain properties, than we can make falsifiable predicitons. For example, if God is as strong as a human, we can prove that God couldn't have created the Earth. Does that tell you anything interesting about religion?

Very likely, each fusion plant (if they ever exist) would require, ironically, a fission plant next door to provide the power required for the magnets.

The magnets, and wiring won't be cheap. The power delivery and control won't be cheap. I'm not sure how this would be amortized into the cost of the power, without making it 2-3x (or more) more expensive than alternatives.

We can build, and we need, nuclear plants now, to be able to generate cheap/plentiful electric power. And if we don't we're basically going to have to push the brakes on EV deployment. Or light up more NG/Oil plants to provide the power for those.
Yes. The majority of the population doesn't experience the things you have, as unfair as that is. So I think the person you're replying to has a point.
Doing something with low-grade heat is hard and often futile. E = (Th-Tc)/Th. Look at a gas turbine. There's a succession of turbine wheels, getting larger towards the end. Each is running off the exhaust of the previous wheel, at a lower pressure. If you added another, larger, turbine wheel at the end, you'd get a little more energy out, at higher machine cost. The turbine ends where adding another wheel is not cost-effective.

Starting from the exhaust at that point means you're competing with turbine manufacturers who decided they'd reached the economic limit. That's fighting the Second Law of Thermodynamics.

The hot end temperature for fusion systems is quite high. Tens of millions of degrees at the plasma. Fusion has lots of problems, but thermodynamic efficiency is not one of them.

The dream is that somehow that high temperature plasma from the fusion reaction is run through a hollow coil to generate power by magnetohydrodynamics. No turbine required.

Somehow. Maybe someday. No clue how to do this yet.

I think a fundamental misunderstanding is conflating Linux style system package management

A collection of resources that are inserted and removed into standard locations plus metadata used to retrieve additional resources many times including some that may be shared between multiple packages including but not limited to dynamically linked libraries and actions to be completed on addition or removal of a package.

and the fundamental concept of a package manager

A tool that provides a standardized set of steps easily add or remove one or more resources to or from a system from a previously configured set of sources without the user needing to manually attend to the details of each installation.

A package manager doesn't inherently impose any sort of constraints on how such packages are retrieved, their requirements met, or their operations actuated. It is the simple mapping between clicking or typing install foo bar in a singular interface and foo and bar being installed on your system. Foo and Bar could be msis individually retrieved from their respective web pages each bundling 100% of the resources needed to run and depending on nothing outside themselves. That is to say the result of running install foo bar could be the EXACT same result as navigating to each respective website, finding the appropriate download, running the installer, answering any questions, disabling any adware or toolbars and waiting for each routine to finish save only that you can't accidentally install malware, you don't need to google the website, its trivially repeatable and suitable to automation.

In that context even if you don't like Linux system package managers it is incorrect to reject package managers in general as they are strictly superior to the alternative of manually retrieving the same packages to the web and in no way impose the things you dislike about Linux system package managers that you are concerned about.

Although you may competently perform that task in fact the act of retrieving and installing software is one of the largest source of infections among users. Removing this source of challenges is as useful as the time saved by being able to run install foo.
We are pretty much in agreement. My point was that the OPs statement that there is no point in getting a vaccine if you are not going to get COVID was nonsense.
This whole clusterfuck of states vs. the federal government on vaccination requirements is a big clog in the pipes and a bunch of unnecessary headache.

Realistically, at what point is the US at "terminal velocity" on vaccination?
Not really. While it is true that we have not been building nuclear reactors in the last 40 years (and that, therefore, all knowledge is basically lost, leading to the insane delays we're seeing in the EPR), this is mostly a political maneuver to win the ecologist vote. Hollande closing down Fessenheim when it was good for an additional 20 years at the very least is a prime example of the clownery at the head of this country.
You’d build more central for that though, no? Otherwise you’re just covering a lot of ocean (until inter-sat links are up and running).

If Amory Lovins had designed a nuclear reactor that would be unaffordable to build it would be

https://en.wikipedia.org/wiki/EPR_(nuclear_reactor)

You can make the case that regulation inflates the cost of nuclear power plants, and that's somewhat true, but the deep problem is the cost of the steam turbine and other facilities (e.g. heat exchangers) to accept energy at the low temperatures that the LWR works at.

All of that is so big and expensive it would be hard to make the economics work even if you got the heat for free.

A liquid metal fast reactor or a molten salt reactor or a high temperature gas cooled reactor could power a closed-cycle gas turbine

https://www.osti.gov/servlets/purl/1221819

which would fit in the employee break room of the turbine house at a nuclear plant. Such a "fourth-generation" nuclear power plant might have compelling economics to build, but it's hard to believe anybody is going to start and finish an LWR outside of China.

It's little appreciated that the cost of the steam turbine is what killed coal circa 1980. Once GE adapted aerospace turbines for low-capital cost power plants on the ground, it made no sense to build more thermal coal plants.

In the late 1970s you see various attempts to save the coal industry, plausibly you could have gotten better capital costs pyrolyzing the coal and running the gas through a gas turbine. This kind of technology is making a comeback because it can be coupled with carbon storage to make CO2 free or CO2 negative energy.

I would add only one thing to the article. Algebraic data types are so great because they are so dumb. ADTs are inherently stateless, for example (as long as you don't put stateful things inside them). This makes them extremely easy to reason about: they're no harder to reason about than an integer is.
This is of course because in 2021 an overwhelming number of consumers are finally pushing for crypto currency payments.... /s

Seriously though, if speculative assets are your thing then crypto is great. It's still not great for the average consumer to use for payments.
Offtopic, but while I may have nerdy GISers gathering here I'll shoot my shot.

Someone knows what is a common/standard way of displaying vector information (points in this case) without having that information scrape-able? Is that even possible? I have a project where I want to sell some georeferenced data and be able to show said data (without all attributes, but showing all points) to potential customers in a map, but IIRC I've never failed to scrape vector web map data so I'm not sure it's even possible. I could imprint them in the tile rasters but then they wouldn't be interactable. Thanks

I don't think it is possible to make the distinction. It is too late unfortunately. I'm vaccinated and I'm ok with people making (what i view as) bad decisions. The fundamental issue here is a question about the role of government: let people hurt themselves or have a nanny state. I don't think anyone would listen though and I'll get lumped in with the antivaxxers regardless of the nuances of my opinion.

With node.js, the cold start problem is caused by how node loads files. For each file it does about 10 IO operations (to resolve the file from the module name), then load, parse and compile the file.

If using any file system that is not super fast, this amounts to long delays.

> The US government, and nearly every government, has a history of lying to people.

This is something you should work to fix rather than just say things like "but the other party lies a bit more, so I also have to lie to defend myself! And people doesn't listen anyway so why does it matter if I lie?" etc. I see so much bullshit people use to defend their sides lies and deception here.

To me ensuring the government stops lying and deceiving the public is priority number 1, every other issue is second to that (as long as the country remains a democracy). This goes for your side, no matter which side it is, and no matter how much the other side lies and deceives, I'll condemn you if you lie and deceive. If you disagree then you are a part of the problem, and people like you are the reason the government can freely lie and deceive the public as they do. Governments only stops lying and deceiving when the public strongly reacts to it every time they do, ignoring it just because it helps your cause is how they can continue to lie and deceive.
> If you can’t explain why you’re doing something

It's not that I can't explain it, it's that it does me no good to do so an in some cases makes things worse.

Where human factors are concerned, software developers in the large (which noteworthy exceptions), are so deeply in denial about what is easy and what is difficult that it's downright toxic. Especially when considered as a whole. Yes, this task is not particularly onerous by itself, but it's one of twenty tasks we have to juggle all the time, and that's simply ridiculous.

I have reasons for most of the things I do. I could write chapters for (someone else's) books about them. But I'm not going to explain them to people because they'll just try to line-item veto everything to try to protect their ego, turf, or both. Complementary practices (those with a multiplier effect) typically have very little payoff when you eliminate half of them. It becomes a self-fulfilling prophesy when you block enough of them that the overall improvement is in the low double digits, instead of say 50% spread across six behaviors.
