I have read two anecdotes online, but would it be possible to order an outlet or 'socket' from the UK Amazon, along w/ a kettle, and wire it into its own dedicated 20A 220v US circuit?
It's quite popular in Europe and extremely so in Israel (IIRC they have >85% penetration there) so it doesn't seem unreliable infrastructure or expensive SMS would be the main factors in every place. Though at least in my experience, in europe it seems mostly used for small-ish "trusted" group chats to shoot the shit or prepare/synchronise stuff.

Yeah, "phoneticity" is a new word for me, but I'm assuming you mean retaining the (sometimes bizarre) original spelling of loan words so that it's clearer where they came from.

In a language like Polish where rules are rules, I think you will be able to see fewer shifts in texts. I think where you would notice a real difference is if you could get a recording of a Polish speaker from 1545. (That is, if you could somehow get a recording from 1545 without somehow also making it available to most of the people since 1545. It's going to be interesting to see 1000 years from now how the availability of recorded media at scale is going to change the basis of new language evolution.)

Yes, but even if the block time is longer, the probability that I will "win" the block goes up. Someone has to mine the block and if half of the competition goes away my chances go up. This incentive will counter the temptation to stop mining, dampening the effect you mention.

A Multi-Trillion Dollar Blockchain Use Case
At its inception the appeal was the "multi-stage optimisation system" and the virtual instruction set design (from https://llvm.org/pubs/2002-12-LattnerMSThesis.html)
Voting comes up a lot as a use for blockchain, but I've never been convinced that a regular public database wouldn't be better - generally the government has to be trusted in some way, and gets to say who can and can't vote, so blockchain's main benefits (trustless+permissionless) aren't needed.

Payments is definitely something blockchain can do better in some cases
Succinct and clear. Thanks!
Let's see how the analysis was derived:

> Note: Assumes China wholesale price ($0.06/KWh), using listed specifications for Antminer S9 (13.50 TH/s), adds 30% cooling & operational costs, assumes retail is 30% markup from wholesale hardware price, 52-week depreciation schedule (Bitmain offers 180-day warranty). No transaction fee or pool fee. Hash rate and computational difficulty as of Feb. 6, 2018.

The biggest sunk cost is on the hardware price. Assuming 30% markup that too in China on a China build product seems too high for me.

Anyone based in China can confirm the retail markup on Antminer S9?

Seconded. I'm almost certain they are, or at least, they're pretty damn hard to stop.
I'm surprised that nobody has mentioned what seems to me to be the obvious precipitating factor: that some guy went on national TV on Jan 30 and boasted that he was responsible for a massive increase in the stock market. When I saw that I immediately felt a warm and fuzzy feeling for the fact I had decided not to buy any stocks (except AMD) over the previous few months. I think that many people who had only half been following the market heard that claim in the speech, causing them to pay renewed attention to market values, check on their portfolio, realize that there was clearly a bubble, then decide to sell.
The specter of rising interest rates in the US (driven by higher inflation expectations) appears to be a factor.

Fast-growing companies which are investing aggressively today and whose profits lie far in the future, in particular, are exposed to rising interest rates, due to the higher duration of such companies' cash flows. Duration, for those here who don't know, is a measure of the sensitivity of present value to interest rates.[a] Duration rises with the amount of time an investor must wait for cash flows, and vice versa.

For example, the present value of $100,000 of cash flow to be generated in 10 years, if the 10-year rate is 2%, is equal to $100,000/(1.02^10) = $82,000; if the 10-year rate rises, say, from 2% to 3%, the present value declines to $100,000/(1.03^10) = $74,000, or a -10% decline. However, if the $100,000 in cash flow is to be generated in 30 years, and the 30-year rate rises from 2% to 3%, the present value declines from $100,000/(1.02^30) = $55,000 to $100/(1.03^30) = $41,000, or a -25% decline. In this example, an increase in duration from 10 to 30 years changes the sensitivity of present value to a 1 percentage-point rise in interest rates from a -10% decline to a -25% decline. The longer an investor has to wait for cash flows, the greater the sensitivity of present value to changes in interest rates.

The same ruthless logic applies to companies. The present value of companies whose profitability is in a distant future declines much faster when interest rates rise than the present value of companies certain to generate cash flows in the near future. Until recently, due to historically low interest rates and no prospects for inflation, the stock market has been rewarding high-investment companies that are sacrificing current profits for growth. If interest rates continue to rise (along with inflation expectations), I would expect this pleasant state of affairs to change abruptly -- in which case, strap on your seat belts!

A few problems with that analogy:

1) Mining isn't required to use the network

2) You don't have to pay any specific "club" to start mining. You need to be able to generate hashes efficiently, how you do that is up to you

3) It's still unrelated to what "permissionless" means in this case

"Permissionless Blockchains allow anyone to participate. The transactions are validated and processed by votes / consensus. A vote does not depend on having a prior identity of any kind within the ledger and no pre-existing trust is assumed between participating nodes."
I guess the model has changed. This is bad for your average unicorn startup employee though, liquidity for any real purpose is limited. There's no price transparency and there's no upside. Maybe this is a strategy to push for deregulation. But it is fleecing the public in another way by restricting assets for purchase even if the goal was to prevent outright fraud originally. All of that money has gone into housing, the stocks that we can buy... But there is also massive consolidation being driven by technology. So there will only be a few winners by definition. This is why China and Russia closed their tech markets to US companies.
Really? To be honest, although I'm a marketer, even as a consumer, I believe if I don't accept the parameters and terms of the application, I shouldn't use it. Obviously that philosophy is only really eligible for private sector organisations, but GDPR holds public ones to a higher bar in any case.

IANAL, but I also think a lot of companies will be well argued on using "Legitimate interests" as a basis for processing instead for a lot of things.

Then others will argue on "Consent should not be a precondition of signing up to a service unless necessary for that service." and use "processing is necessary for the performance of a contract" as the basis (especially if there's money involved).

Obviously, the large companies will be able to handle this better and employ decent legal teams to argue for using those basis' - not because they're "good actors", just they've got the cash and knowledge to argue better. It's the smaller business owners (who as with VAT MOSS) are going to be screwed over the most.
If you start a new blockchain then you probably don't need as hard proof-of-work problems as there is now in bitcoin.

One thing that the article is missing to discuss is that for a blockchain to truly work there needs to be a reward system for the nodes to participate in the network (basically to cover the cost of this crazy expensive infrastructure). Ie. a cryptocurrency that can be mined.

> The US ranks 14th in happiness ahead of the majority of European countries.

The top 6 in said index is occupied by European countries - and all 8 European countries ranked before the US in said index are routinely bashed in the US as being prime examples of "socialist" hellholes.

> The US ranks 6th in productivity, again ahead of the vast majority of European countries and far ahead of the European average[1]

Well, it's not that hard to beat European countries if you're working 300 hours per year more than them... and the core question is: how much of the US "productivity" originates from the scamming going on at Wall Street, i.e. it has no meaningful human labor associated by which this "profit" was created?
That just copies the data, its doesn't do imports or initial fetching of data - which running the application in and IDE does for me.

To be fair the term "blockchain" is too broad and generic to give it a very specific definition. I think that's a big reason for the hype, like "cloud computing". It's so vague that nobody really knows what it's about, if you actually decide to get technical you lose 95% of the audience as soon as you utter the words "cryptographic hash" or "public key cryptography". So you can just make any bold claims without going into details and still be sort of right. I can say something like "blockchain technology is going to be big for avocado cultivators to be able to audit production year after year". Does it make any sense? Who knows. But it keeps people going.

And it's probably true too. Blockchain technology is here to stay. Cryptographic hashes, public key cryptography, merkle trees, hashcash, peer-to-peer networks, all that is here to stay. Of course, all that existed before the Blockchain, in the same way that servers existed before the "Cloud" but it doesn't matter, it's all about that sweet branding.

You don't need to mine to make Bitcoin transactions. By "permissionless" people tend to mean that you can send money to and from another user of the system regardless of the legality and without a payment processor to intervene and forbid it.

As a really quick hint, if somebody pushes blockchains as a solution for anything but cryptocurrency and managing cryptocurrency based on the state of other cryptocurrency, or a solution for Zooko's Triangle, they're selling a lie.

EDIT: the reason for this is that if the chain ever needs to touch something that isn't entirely stored within the chain - for example, the number of avocados picked on a certain day - it needs a trusted oracle to tell it that. If you have a trusted oracle, you can trust that oracle to host a bog-standard SQL database and avoid this whole mess, unless your boss is breathing down your neck about using "blockchain" so your company can look cool and hip to its investors/clients.

Verifiability by an individual voter - given their receipt (hash) they would be able to verify that their vote (transaction) was in the chain that produced the final tally.

I am in general a blockchain skeptic - I think in most cases, there’s just enough trust to just use a centralized database - but voting seems like a good usecase for blockchain, as it provides voters with a receipt and it’s designed for auditing provenance.
Again, I think you’re naive. The big tech companies and anyone with EU operations will comply, as they should since they are operating from those jurisdictions.

But other small and medium websites all over the world that don’t have EU operations will mostly just ignore this, as they should. It’s going to be nearly impossible to enforce for those companies, it’s a violation of national sovereignty, and half the regulations don’t even make much sense. How exactly are you supposed to avoid storing the personal information of EU residents when personal information includes IP address and that EU resident can be anywhere in the world? Or you have to delete the info if asked, but other laws require you to keep it? Now every medical facility in the world has to have entire new compliance procedure just in case an EU resident stumbles through their door?

Yeah, color me skeptical. You can pass any law you want, but it’s only as good as your ability to enforce it. If you think the US is going to help the EU collect multiple-million-dollar fines from some small business in Oklahoma, well, you’re going to be very disappointed.

We’ll see, but I doubt that in a couple years things will have changed all that much.
Filament Runout Sensor for Your 3D Printer
Thanks this is really helpful. 4% for the 20th century is definitely closer to 3 than 6.

However, the assumptions have only 80% in capital gains while this should be much higher for long term investors.

If you’re investing in a 401k then you add about 1-3% because you won’t be taxed each year and those gains are compounded.

And it’s assuming 1% admin fees from 2000+. This is way too high and is closer to .1% starting in the 80s with vanguard index funds.

So if you invest in tax deferred index funds you are looking at 5-6% after taxes and inflation.

But I like the way this matrix displays info and I want to find a version with assumptions for efficient 401k investors.

>To me "true blockchain technology" in the bitcoin sense of the design is open, permission-less and only has a few real applications.

Beyond cryptocurrencies? Go on, I'm all ears. I'm always amazed by how often I hear that claim (on HN and elsewhere) and yet nobody seems in a rush to be specific about it.

The only other use case for blockchains I'm aware of that makes sense to me is some sort of IP protection scheme (mentioned in the article too). If you make a discovery you can write down "$me has discovered this and that", hash it and put it into the blockchain. Later you can use it to prove that you actually had that information at that date without needing any trusted peer or institution.

But even then it only works if the chain can't be attacked you still need the currency aspect to motivate miners (or shareholders in a PoW scheme) to protect the chain.
