It's a fundamental way to learn.

E.g., suppose people tell me I'm a real funny person. Let me test that.

1. I remember a joke from a professional funny person widely considered to be one of the best.

2. I tell that joke to the people who told me I'm a real funny person.

3. I measure the laughter I get.

If the laughter is different-- e.g., if the people tell me this is by far the funniest thing I've ever said, then I know I've got a lot more to learn about jokes. On the other hand, if it's the same amount of laughter I usually get, perhaps I've got a real talent here.

Of course, it could be these are just close friends and they are primed to think anything I say is funny. Nevertheless, just the act of telling that joke as if it were my own gives me the experience of the timing and emphasis of that comic. It's a gain of knowledge.

That process is an order of magnitude faster on Reddit with control-v. Who know, maybe it even makes that person a bit more cynical about "karma" points. If so, they've at least become a less naive person.
Electrolytic hydrogen plants of up to 250 MW were constructed in the 20th century by the use of smaller electrolysis units in parallel. All of them were for producing ammonia from hydrogen. See table 3-2 on page 99 of this NASA report from 1975:

"Survey of Hydrogen Production and Utilization Methods"

https://ntrs.nasa.gov/api/citations/19760008503/downloads/19...

250 MW, Rjakon, Norway, built 1965

170 MW, Kima, Egypt, built 1960

125 MW, Nangal, India, built 1958

90 MW, Trail, Canada, built 1939

25 MW, Curco, Peru, built 1958

> The ulterior motive couldn't be more obvious.

You haven't explained it well enough to claim it's obvious.
You think it's a money grab (of some sort)? or that the operations which were barely telling in 2015 (https://thediplomat.com/2015/08/satellite-imagery-from-china...) but of questionable efficacy in 2019 (https://news.usni.org/2019/05/03/report-china-cant-execute-m...) might all be a misunderstanding?

The danger is real enough (https://www.taiwannews.com.tw/en/news/3980026, which may be a rumor) but Taiwan is sure enough to spend money on exercises (https://www.scmp.com/news/china/military/article/3076947/tai...) and the movements https://www.thetimes.co.uk/article/china-simulates-island-in... which promoted a legitimate fear, that there would be an operation during the US election. https://www.taiwannews.com.tw/en/news/4034710, obv that didn't happen.

There's a stated intent to enforce a "One China Policy" and that's not going to happen without a large-scale troop movement.
What’s your point other than people generally sell large projects with a low up front number and it ends up being higher. Investors don’t get the 3-4x return they wanted and have to settle for 2x. Or it takes longer to pay itself back.

Solar and wind are expensive too if they are overbuilt 5x or backed up with enough batteries to be a firm source of power.

How can anyone argue against nuclear being part of the solution of reducing carbon emissions just because it takes more imaginary monetary tokens to build?

Who cares who is building the reactor? Russia and China have the skill and the will to make it happen while everyone else is wringing their hands and continuing to pump out co2.
Agreed with this, the tooling for pumping out presentational only components is already there.
Show HN: Simplified EU VAT validation (for B2B sales)
Hi HackerNews,

first time solopreneur here (if that is a word) and my very first launch of a product which I built alone, start to finish. Not sure what to expect. I am super pumped and excited to show Vatfy to the HackerNews community and am very nervous (and scared to death at the same time) of what you guys think of my niche product.

I created Vatfy because I did not find a simple and cheap alternative to making my invoices tax compliant. Yes, there are other solutions out there that do VAT validations, but most just do this initially (one time) or are insanely expensive (at least for my gusto). This kind of sucks if you are invoicing on a monthly basis as a SaaS (for example).

So I created Vatfy to validate EU VAT ID numbers, calculate prices for B2B and B2C customers based on their location and help me figure out if you want to invoice net or gross pricing (with and without VAT percentages), be able to look up up-to-date VAT rates as well as have a place to store all my validation evidence in case the local tax authority ever wants to do an audit.

Also very unsure about pricing at the moment. 100 free validations per month is a lot, but I always had the small business user in mind, who cannot or does not want to purchase a more expensive solution.

Any feedback to Vatfy more than welcome!
This'll generate the kind of code you'd expect to get from a $60 themeforrest template. If you don't care to or never need to dig into it or reuse anything out of context of the prefab template you'll be in an 'OK' place, but anything more than that and you'll likely be not much better of than if you just started from clean.

Resetting Your GE Smart Light Bulb (2019)
> The vendor (Areva NP) and the utility are in bitter dispute over who will bear the cost overruns and there is a real risk now that the utility will default.

With the contract TVO signed with Siemens and Areva for the plant they will never end up having to pay all the cost overruns. It was basically a fixed price contract.

What ended up happening is Siemens got the fuck out of the deal (it was originally a Siemens and Areva joint project) and French government broke up Areva Group into smaller entities and took a hit on the failed project. From the legal fighting Areva agreed to pay TVO 450 million due to failing to deliver on time with some extra money going one way or another based on if it will deliver in the new revised timelines (ended up Areva having to pay TVO another 450 million).

According to TVO at the end of the day the project cost them 5 billion instead of the original 3.2 billion with Areva saying it cost the 8.5 billion so Areva took a huge hit on making a bad contract and/or failing to deliver.
The future looks bleak for humans, better get a geiger counter and carry it with you.
Sure, but even a grain of sand that I can't build on or walk over is still going to be annoying. It's still just rude no matter how small you think the problem is.
If you scale this up you're also having more Area. If that hall contains all the waste from decades of energy for France, I'm sure we can also build 1 in Germany, Italy, and every US state.
It is insane to me the amount of pain email not being secure by default causes across the economy.

All these apps implementing in-webapp messaging systems that suck, then sending me an email with no information other than that I got a message in a system I look at maybe once per year.
It's unlikely to hit 0 even at night, no reason to stop all the windmills and hydro, and there will be stored energy buyers and sellers. But there won't be production guarantees to some level based on anticipated demand.
In British Columbia Canada we are building a 1000 MW hydro plant called site C for 10-12 billion. We have been doing studies on the site for 30+ years and it will be 10 years construction time by the time it is finished.

Nuclear looks pretty good in comparison.

I still don't understand why nuclear waste needs long terms storage. With Burner reactors you can produce waste that only needs storage for 100s of years, not 1000s.

Its easy to store and manage, basically it can just stand in a field, doing nothing for 100 years.

The 'waste' is not waste, its material we might want to use in the future and putting it into some 10000 years storage is idiotic.
The half life of Plutonium is ~24k years. That's way beyond a time frame we have any grip on. Then its still very, very dangerous. Uranium (nuclear fuel) has a half life of 200k - 4.4 million years. Then its half as dangerous.

CO2 has a half life of ~ 10 years in our atmosphere btw.
I think the point is that Taiwan being free of Beijing has a lot of strategic importance to other countries (basically all of the West). Crimea is really only important to Russia and Ukraine.
It’s not necessarily a feature comparison, but I’ve found it much easier to just “try” things in Rhino. Solidworks is best when you already have a clear idea of what you’re building. In that way, our industrial design team would use Rhino and then hand it off to the mechanical engineers to rebuild it in Solidworks.

While you're probably right, I always find it oddly weird sometimes how logical these things can be. Like copying tattoos and mannerisms. On one hand, it doesn't make sense to pretend to be someone else, but if you look past that, the steps were frighteningly logical. And this is where I think it dovetails into other scams. I'm not sure if the scammer is above it, a part of it, or unaware of it sometimes, but what they present and what you see isn't really the whole story.
I have a suggestion for ground rules as far tooling is concerned.

1. If it requires a GUI, at any stage at all, it's broken.

2. Unless it's controllable through scripting, it's unfit for purpose.

3. If it doesn't support real-time observability and control via an API, it's useless.

This space doesn't need any more "products". We need a good suite of composable tools, not more C-suite bingo sheets.
Yes, this. I am a huge fan of thorium breeders and there are few other minor advantages but people have gone of the deep end.

There is almost no way to generate energy without waste for future generations, CO2 for fossil fuels, nuclear waste, electronic and heavy-metal waste for solar and batteries.

Saying we should only use methods that don't provide waste is saying we should reduce energy consumption to 1-5% of current global and ditch all cars, ships and airplanes. Even if you are 100% morally right you're never going to convince humanity of that.
I've been thinking about nuclear this last week and i have some assumptions that i would appreciate if somebody more knowledgeable can quickly filter:

We want more energy per person in the future.

Stable energy is required to make industry sustainable.

Stable 'free' energy allows you to do really cool new things (like melt trash for resources?)

Waste & environmental impact is negligible compared to fossil fuels.

A nation needs to agree to the risk/reward of a nuclear power plant, it must be owned and payed for primarily by the government.

Having a country/state that offers free energy will pay itself back easily.
Cost should not be an issue, 20 % of GDP should be on the table.
( Money is made up, Jules are real ).

Solar and wind are mostly done innovating. Nuclear has a relatively clear path of improvements ahead in terms of $/joule.

Storage based on hydrogen or thermal are too inefficient and don't scale well enough to power homes and industries during the winter.

Any comments are welcome.
I think you are forgetting that there are nuclear missile submarines within striking distance of every major Chinese city. This is a game of chicken, not a game of "who has better logistics."

Imagine how overbuilt and under utilized a communications network would have to be in order for it to work the same way people imagine solar and wind power can be transported across the country.

Networks offer the best return on investment when they are fully utilized not sitting idle.
I am not sure the American underclass (a large part of Trump’s support base) is faring much better. Even with larger unemployment, inequalities are still not as bad as in the US. Several countries have similar problems, whether it takes the form of 10% unemployment or working-class poor.
It's always windy somewhere. You just need to expand the electrical grid.

We are still far from the point where we have enough wind that any of it goes unused.

Also what is the cost of storing that energy? It's so much cheaper to generate it might still come out cheaper.
> These companies want to commoditize their complements---"open source" means we can reap what you sow and sell it to our customers---but not the proprietary code they use to differentiate their clouds.

I've worked with numerous SaaS businesses who run open source for as much external software as possible because it has better economics at scale. They want tight control of software configurations, ability to diagnose problems themselves, quick application of security patches, etc. It's not cheap; you have to hire highly qualified engineers to make it work.

The approach makes more sense as the business gets bigger, in the same way that it makes sense at some point to design your own data centers, own hardware, etc. It's therefore not surprising to see large businesses go all-in on open source.
I think this is negligible compared to the “era” that it would start. Taiwan is seen as a more westernized country and an attack on Taiwan would start a cold war-like era with China and the western world.

The false positive in this case is filing a false police report. That’s illegal in the US, and probably exposes the rental car company to civil liabilities (generally, contracts that allow one party to commit crimes are unenforceable, so I’d hope that extends to eliminating the binding arbitration clause, though I am not a lawyer).

The police should pursue it cases like this, and arrest the decision maker in the organization that caused this to happen. If it’s been happening repeatedly, the person’s sentence should be increased accordingly.
If you are going to use cement to build anything, a nuclear power station is probably the best use for it.

I don’t think anyone is ignoring the problem, having huge amounts of zero carbon power is the starting point for lots of things that will let us solve a lot of the harder problems like cement, or jet fuel etc.

Given that mountains are a result of geological activity, this is for sure the worst place to store it. You'll have a better chance digging out a big hole in the desert - which the EU doesn't have.
we are in a climate crisis and wind/solar alone are just not going to cut it.

And nuclear is the safest power source (measured in deaths/twh) which humans have been using for decades.
> doesn't download it, it's not a excuse, it's a filter

If it's a decently large project, sure. But if it's a small project with only a couple contributors who I've never heard of? There's the potential for that to be hiding malicious code. Plus the potential complexity of getting a project that's only ever been built on (say) 2 computers to successfully compile and run on my system. Plus figuring out whatever build system and weird flags they happen to use. And potentially wrangling a bunch of dependencies.

All that just to take a quick look at a language that might not actually be of interest to me in the end. The browser offers huge benefits here - follow a link and play around in a text box. It just works. (This is also why I use Godbolt - I don't want to bother with a Windows VM or wrangle ten different versions of Clang and GCC myself.)
But the only definition we have for mental illness is whether your situation falls under some category that we have a name for. It’s a slippery (and fuzzy) enough slope having designations for illnesses that encompass a huge portion of the human condition (see Rosenhan). Much worse if we also include things that don’t have entries in the DSM. It would be trivial enough to say that anyone you have even mild distaste for has a mental illness.
> Conciseness (not mere terseness, but clarity and terseness together) greatly aid readability. Verbosity is not zero-cost.

I've been coding for 40-ish years. I've never found this to be true. Simple expressions are (in my experience) more readable.

I understand it like this: to understand a complex expression you have to unpack it in your head to a simpler version in order to grok it. This is an operation you don't need to do if the expression is in the simpler, more verbose, version in the first place.

This is a known thing in writing, btw - complex sentences are harder to read. If you want your audience to understand you, write more, simpler, sentences.

There was a Reddit bot a few years ago (aptly named 'trappedinreddit') that would automatically post the previous top comment on reposts. Predictably, those comments would get upvoted again, and trappedinreddit would end up with the top comment on most posts. It lasted a few months before the bot was outed and it went away.

Doubt. Weather systems/patterns are often extremely large.

Insanely high compared to the cost of producing it.

For one common naive case: Storing the energy in Li-Ion batteries in e.g. a Tesla Powerwall: $437/kWh.

If anything, Taiwan has a claim on China as sovereign land.
This is Stupid, yes, but but it would (very roughly) be like if in 1066 the Normans had lost -- and then they kept claiming "Britain is ours!" Years later. Uhhh... No. Britain would be the Anglo-Saxon's. No question.

"Intel usually considers FP16 to be the optimal precision for AI, so when the company says that that its Ponte Vecchio is a 'PetaFLOP scale AI computer in the palm of the hand,' this might mean that that the GPU features about 1 PFLOPS FP16 performance, or 1,000 TFLOPS FP16 performance. To put the number into context, Nvidia's A100 compute GPU provides about 312 TFLOPS FP16 performance. "

wow
China has squashed the virus, its placing a major emphasis on consumption, its navy now rivals the US. Taiwan is home to the largest semiconductor fab in the world and there is a worldwide shortage of semiconductors. Other countries around the world are struggling to get the virus under control and they are dealing with stuttering economies. The US is in the midst of a culture war where nobody can agree over economics vs virus protection or interventionism vs isolationism. The dollar is in a shaky position between massive stimulus and the increasing interest in crypto. I’d say China sees this as their best opportunity to make a move with little opposition.

> Nuclear energy without subsidies is not sustainable at all.

This is nonsense. We are basically using 60s technology that has some of these problems.

A modern reactor facility could be 10-50x smaller for the same output and that makes think like decontamination cheaper as well. Also, these facilities can run 100 years potentially, so the amount of money required for decommissioning is amortized of gigantic amounts of energy.

There is nothing inherent in nuclear that make it super expensive or unsustainable.

What would that look like? Running away? Because that behaviour pops up in news often enough.

Conversely, there’s learned helplessness — discovered by animal research and yet also demonstrated in humans. Do humans demonstrating this lack free will?

> One could argue that we still don't know the human brain, so how can we exclude that animals haven't what it takes to understand free will?

I’m not asking if animals understand free will, but if they have it — humans don’t seem to understand it even though we can talk about it (judging by the difficulty of nailing down a definition) so I would actually be very surprised if it turned out any non-human animal understood it.

I don’t understand the point you’re trying to make about bovine aggression?
