To search for ideas of what would be a good candidate for soaking up excess electricity, look at capital cost per watt consumed:

For instance, if I have an efficient computer system that costs $100 for every watt consumed, it's not going to make sense to run it only during that 20% of the time there's excess electricity. The effective capital cost is then 5 times greater. I'd be better off investing in a battery and extra solar to allow it to run it 24/7.

But if, instead, I have something which has incredibly low capital costs, like 10 cents per Watt consumed, and which can tolerate being shutdown and restarted, then even though it might only be operating 20% of the time, the effective capital cost is still just 50 cents per Watt, even cheaper than a battery capital cost. So it makes economic sense to use that to soak up the extra electricity demand.

This is why the key for hydrogen electrolysis isn't so much efficiency but capital costs: a variable-renewables-heavy grid will have enormous amounts of excess electricity at times, but only for fairly brief periods. You can't economically "store" that electricity using hydrogen if your electrolysis capital costs are so high you need to run your electrolysis cell 24/7!

If you want to make the hydrogen economy a reality, FORGET about hydrogen cars. Focus on hydrogen electrolysis capital costs!!!

Ask HN: Why don't smart routers use phones to callibrate?
I've had several band switching and high powered routers, but the problem is that they can't see the whole problem.

Switching channel based on local traffic is a reasonable idea, but it doesn't know what the conditions are like in the room/area of my house with bad reception and I'm yet to encounter one that factors in that side of things.

Surely you often want to optimise for the place with the poorest signal, which might have problematic insulation that weakens your signal, and also weakens the signal before it reaches your smart router, so it doesn't know that it's a poor band choice.

Surely an app or method using your cell phone or other wifi device would make this a more useful technology.

(and I do know I can download apps and test manually - while logged into the router admin, I already do)

Thoughts?
The delays have little to do with technology, and a lot to do with regulations and bureaucracy. Largely put in place to combat money laundering, fraud, terrorist financing, etc etc. Yes, there's some small banks that have horrible APIs and shoddy servers, but for most transfers the delays come down to things that if cryptocurrency were ever mainstreamed would be tacked onto it.

That is why it takes time to get approved on coinbase and other exchanges that try to follow the law.

> it was always about who would get it first without getting busted

The question is, to what kind of person, and how would they realize they have been busted? Eichmann demonstrated that even sentencing and hanging someone doesn't necessarily make them understand what they've been sentenced for and why they must hang. What is left is to weigh the guilt of judging someone without the mental capacity to understand what is going on, and the guilt of leaving them destroy and kill yet others. It's not fully satisfactory either way, that boat kinda sailed.

What does "blockchain" even mean in this generalised context? When we are talking about crypto currencies, it is a distributed database with a consensus mechanism that is extremely costly to run. But this is not something you would need or want in most other situations, because there is always some degree of trust with your counterparties (and legal recourse if necessary).

If we strip away the consensus mechanism, all that is left is a trivial data structure that anyone with a CS background could come up with. So, the question becomes where the real value proposition is in "blockchain technology" outside of the realm of crypto currencies. What are the things you can only do with "blockchain technology" that cannot be achieved with existing technology? It looks more like a marketing buzzword than anything that has actual merit for the average use case.

(as an aside: generally only the large legacy carriers do this type of price discrimination.) Find one flight that's not "this is so cheap I don't care" (basically at least a few hundred dollars). Then, change the search mode to round trip and find the same departing flight. The lowest round trip price will be shown.

“governmemts are thinking of putting assets and laws on Blockchain”

Two things: this statement is so vague it borders on meaningless. What assets? Who will put it in there? The president? Why would a government do that? Is it free to do or is there budget? Etc.

Secondly, even if we could surmount the vagueness that plagues not just this idea but all blockchain ideas, the Herculean effort required to move governments which can barely move themselves seems like it would delay the whole thing by decades.

It all starts with how vague the ideas are. It really requires simply staring at the ceiling and figuring out precisely what you mean when you talk about blockchain ideas.

> Have you ever tried a normal bank transfer? How long did it take?

For less than $5,000 it is free and instantaneous in the United States (e.g. Zelle). For more, it is free and instantaneous (wire; my bank waves the fee; most charge $15 to $35).

The number one thing holding back the blockchain from becoming a proper database technology is its proponents insistence on applying it to problems that already work faster and cheaper.
It's younger than most technology is when it becomes successful. Much younger when you realise you think about the age of the concepts, designs, algorithms, etc. that eventually become successful rather than a specific attempt at implementation.

Its in my 'Petersons guide to Weather' from the early 90's. Interestingly, it was Kurt Vonnegut's brother who did much of the early research.
I flippantly thought, from the first time about when I was reading about dark pools in the financial times newspaper, the delay in reporting less interesting than I hadn't expected the reporting, I have felt as if the bankers were unravelling their own life support and ecosystem, without realising what they are doing. Dark pools existed for advancing business in a grey area of regulatory distinction. This is the habituated purpose of the modern banker. The most important exposition of the expansion of banks into grey area meaning uncertain legal ground in which crucially the advantage of any interpretation and codification by case law, is strongly to the advantage of who can deploy the greater resources, must be "Wriston" the biography of Walter Wriston, who created the modern Citibank from the National City Bank of New York. Precisely by expansion in grey areas of business.

But the ad absurdam finality of creating ever more custom trading venues, is that you inevitably end up only being able to game yourself. The professional advantage of executing in a public market is replaced by the mind rotting process of writing your own rules and looking for where you can faithfully attest you weren't developing a rule for suitability for your trading desk abilities, you either accept you know that your own rules are already beaten by your own operations and become at best a pragmatist, of you devolve into second guessing the nature of your own company to be able to claim your rules are unbiased neutral and blind to be fair to all comers.

This has turned banks into navel gazers not Watchmen over economic instability and guards of our capacity of production in daily life and ready in case of war. The regulation was wanted by banks to assure the public. This move to reliance on in house mechanisms for all of your flow, eliminate the advantage of regulation. This erodes the raisin detre of regulatory government but it far worse dissolves the conveyance of trust from government institution that the regulated bank enjoys.

I am saying that one day I realised that the behaviour of banks had become self destructive and it wasn't a flu or affliction but a inherent character trait come out of much poorly understood history I think is too important to never let the public see. We need the institutions to function, too.
This isn’t really all that comparable to the Lytro - this is effectively a hack that takes advantage of some Panasonic camera’s ability to shoot 4K jpeg bursts at 30FPS - it racks the focus as it shoots a burst so you can pick from a range of focus points. The subject can still move noticeably in between shots, it’s not a single shot style solution like the Lytro has. I have a Panasonic m43 camera with this feature and almost never use it, It’s just a fast implementation of focus bracketing and you take a pretty big resolution/quality hit.

The new “Dual Pixel AF” sensors in some newer Canon DSLRs is much more like the Lytro, in that focus can be adjusted slightly in a single image capture, no burst capture trickery.

> this comment is like the Triple Crown of dumb GMO arguments

Regarding points 1-5, did you miss that I said it was an honest question? I clearly did not say that it was an argument. I asked precisely because I knew there might be facts I am not aware of. Thank you for filling me in.

> 6. All of this drastically misses the point of glyphosate, which is that it's a very simple, broad-spectrum herbicide that is better understood than the selective herbicides farmers use for non-GMO crops. Glyphosate targets a metabolic pathway present in plants and fungus that isn't present in animals. That's not true of selective (grass- or broadleaf- targeting) herbicides. "Conventional" weed control programs are known to be dangerous to humans, rather than the targets of FUD campaigns.

And this addresses the concern that it may be a carcinogen... how?

> 7. If you're "inclined to agree with IARC" about glyphosate, unlike a significant number of scientists, I have bad news for you about cooking food --- meat or vegetables --- which is also 2A-carcinogenic.

And that also is not an argument for rejecting 2A carcinogenic labeling on glyphosate.

So I ask again: This addresses the concern that it may be a carcinogen... how?

Well, I ask rhetorically. Apparently an answer will not be given, only misdirection.

Sorry but I don't have the energy to debate with people who won't read carefully or provide answers that are not misdirecting. You may have the last word. Good day and God bless.

P.S., "a significant number of scientists" is a fallacious appeal to authority. A significant number of scientists is not the same as having a majority of consensus.
I’m glad some people get it. Banks do zero delay and zero cost transactions between themselves already. The idea that “if only we coukd figure out where to use blockchain, everything would be FREE” is really naive. You take away a banks ability to charge for X, don’t be surprised when Y gets a new fee.

As to decentralized, there seems to be a wonderful libritarian ideal around cryptocommodities but I’m reality they are much more centralized than anyone wants to admit. There are probably 10 people that if they wanted to could absolutely demolish bitcoin.

Too much hype around all of this. Not even getting into the massive waste of power and potential.
Then I don't understand the question, but you can probably make pretty decent guesses about a person's income just by looking at the type of credit card and the issuing bank. And definitely if you include credit card billing address. There's tons of databases that translate a zip+4 to a median household income.
As someone who owned a Lytro Illumn, it was surprisingly a wonderful piece of hardware. Its massive and always gets interesting questions from onlookers. It was clear a lot of effort went into bringing a Shack–Hartmann wavefront sensor into the hands of a consumer. Sure it felt prototype-y, but it wasn't vaporware. It'd be wonderful if they opened up the development environment for the camera itself.

I think the fundamental assumption is that "Satoshi invented a useful solution to decentralized consensus".

What people don't realize is that Satoshi's solution only works if two assumptions hold true:

1. Mining is decentralized: If mining is centralized than relying on proof-of-work for consensus is waste since the centralized entity controls the blockchain anyway.

2. Consensus rules don't change: If you see the threat of #1 and so take power away from miners (like Bitcoin has done), then you cannot ever change the consensus ruleset because aside from proof-of-work, Satoshi did not give any solution to the problem of choosing between 2 chains that have slightly different consensus rules. If you change the consensus ruleset (ie. make any changes where 2 nodes disagree on if a block is valid or not), then you need an oracle to tell you which chain to choose. We've seen this when Core developers chose the 0.7 Bitcoin chain in 2013 and when Vitalik chose the forked Ethereum chain in 2016.

At the end of the day, the blockchain's decentralization is a myth because it relies on false assumptions. Satoshi invented a Rube Goldberg machine that is currently using as much electricity as a medium-sized country (and also enabling things like money laundering, drug trafficking, etc.).
I understand the economic rationale behind this, but I would think that there's automated tools to exploit this segmentation. It'd just be a simple function call to determine if there is any round trip flight (with a certain one-way segment) that's cheaper than the one-way segment alone.

---

I stumbled upon this strangeness while planning out a vacation. I'm basically hopping through Europe so I was buying several one way flights. I accidentally clicked the roundtrip button once and noticed that the prices, in general, seemed lower than the one way. So I checked and lo and behold: they were lower. I ultimately just went with Ryanair because their prices were literally a third of what the next lowest carrier wanted (~$35 vs. ~$120).
> Combined they're sitting at ~$165 billion dollars in created value.

Huh? Bitcoin and Ehtereum are purely speculative assets, they have not enabled any new production or efficient distribution,
they have not increased economic activity. They aren't even marginally useful in electronics production like gold is.

This is like saying printing dollars creates value (though the dollar is at least useful as an instrument of trade).
You are confused on what I am saying. They shouldn’t just rely on booking flights with some private company.

They will never build in house and never have. Just like the military some large contractor will build the plane or spaceship according to their specs.
