Good example. You need roughen it also for better sound quality on the inside.
For Disney I had develop lot of linear algebra optimizations for smoothing which went over my head mostly, so I used symbolic solvers.

We don't have much sound optimization CAD programs, so we worked with light as replacement for sound, and looked at the reflections with raytracers. For the big, expensive concert halls and opera houses.
Our bridges stand. Our rockets fly, and our planes (tend) to not drop out of the air unexpectedly. If not for some healthy logical reasoning, correct patterns of thought, and ordered mental states, then what? Yes, it's fun to discuss this kind of thing, and a lot of what we do is irrational, but it's just as often sophistry as anything else. I note, of course, that you did only say 'nearly', but that's basically exactly what I mean.
Many people solved their lack of money problems through launching blockchain-related companies. The actual systems they launched can't be considered substantial, functional, or often even real, but the (actual) money that poured into their own bank accounts was substantial enough. Does that count?
So far I love working from home, I am more productive than in office, despite parenting.

I'm just waiting for the time to kick my kids to the kindergarten again, to gain a better concentration, then there will be much more improvement.
But couldn't this also be done by publishing the hash in a few newspapers, for example?

I imagine for a court case this would be better. One less thing to explain.

I think for a court case you would have to prove that the block chain is a historical record, not just some data you and your friends made up.

I assume that's some sort of "Faraday bag" for your phone?
In our research group (with shared NFS), we log the history per directory (i.e. the histfile is $PWD/.history.$USER), and we also log the date/time. This has been extremely helpful. Not only checking your own history, but also being able to see others history. E.g. imagine going through some directories of some former colleague who is gone now. Otherwise it would often be impossible to really understand how sth was created, or ended up that way, etc. I mean, properly documenting everything is of course nice, but even if that is done consistently, it will still miss some details. And in practice, it never is done consistently.

I wonder why this is not more standard. Most shells write a single global histfile to $HOME.
I look to Belgium as an example of the ideal world government. Trying to explain Belgium's government would require a wall covered in newspaper clippings and string, but the short form is that there are 6 independent governments with the same power as the federal government, with very long-standing cultural and linguistic strife between them. As a result, it is very hard to do much of anything on the federal level and instead, most decisions are made locally. As a result, despite Gent, Antwerp, and Brussels being about as far apart from each other as San Francisco and Palo Alto, each has a very different culture and regulatory environment regarding daily life. In Gent, it is completely normal to close one of the major roads into city center for a neighborhood festival. In Brussels, it requires weeks of fighting bureaucracy to legally block a side street for a few hours at 6AM with a moving van.

Even larger issues are handled locally. Until last year, even immigration and work permit issues were handled provincially. It would take 3-6 months to get my work permit renewed in Brussels, but after I moved to Gent, it took 2 weeks.

This all works because it is very hard to get national agreement on anything. Everybody knows that they're not going to be able to push their views on the country, so they work to change their local environment instead.

This is all despite the government being (IIRC) the largest employer in Belgium:
I attended SF's blockchain event last year and was fortunate enough to have a discussion with a guy whose startup was working on blockchain app for verifying cannabis from farm to store (and also for providing a marketplace, I think). They're apparently doing well, but I left wondering how crucial is blockchain to what they're doing, as far as customers are concerned. If I have to hazard a guess, I doubt many customers are savvy enough to know how to verify the blockchain of their goods. The app, I imagine, tries to make this easy by showing it in the form of UI, but how would I know if, underneath that sleek veneer, it's not just some good old crud database?

For as long as humans have engaged in trading, we have relied on trust that's built over time. There are bad actors from time to time, sure, but I'm not sure if that's enough of a problem (perhaps it is in cannabis circle) to justify making blockchain a centerpiece of one's endeavor to modernize the purchasing experience.

The same goes for other current applications of blockchain such as trading card games. I left the event feeling most of the presenters just forcefully shoehorned blockchain tech into their applications, with one exception: cryptocurrencies use in countries with oppressive regimes and poor banking system).

The current estimate is that 2/3rds of deaths "due to" C19 are just people who would have died anyway dying a little early.

The relevant number is excess deaths due to C19, which are hard to estimate during a pandemic. That will be much lower than these numbers being reported.

"Ready Player One" came to my mind. I have never been in/played "Second Life" or "Sims". I bought a PS4 in the hope that "No Man's Sky" would become something like that. It had a disappointing start, and I just ran out of patience (and then time) to see what it has become nowadays.

I would very much enjoy a "Ready Player One" universe with the entrance/lobby of "Wreck it Ralph" where you can jump around (imagine pacman with a fully equipped "Half Life" character ;)

The "buying objects" is the thing that will annoy me, people staying hungry to buy 0s and 1s still doesn't make sense. I understand buying Software, but software is a tool that we use to build something to add value.

Was this comment really worth exposing the fact that you don't understand why nearly every store in America prices with 9's?

But since you asked... lowering the price by $11 will require 28% more unit sales to cover the difference. Normally 28% more units would increase COGS, resulting in less profit on equivalent sales, requiring even larger unit growth, but we're talking about software here so let's ignore that. Regardless, I couldn't tell you which works better without some more data.

I will bet you, however, that $39 will outperform $40 in total revenue and profit.

Blockchain usage right now is minimal, largely due to the fact that for most use cases it’s too expensive (the cost is high, confirmation time is long).

For most use cases, Ethereum is too expensive and the blocks are too full, the same is true for Bitcoin.

Once second layer solutions are more mature and layer 1 blockchains are substantially cheaper due to new consensus protocols, you will see more applications for blockchain.

Until then, blockchain is too expensive for the free world, and is largely only somewhat useful to those in failed states.
A very well written article this is.

That makes sense. So, continuing with the git/source control analogy, what’s missing is a distributed mechanism of both publishing new forks and then deciding which of those forks “wins”.

It sort of happens now in an ad-hoc way, if you include blogs and such with big fork announcements that sometimes result in an effective change of ownership, but that’s a slow, rare, unreliable process at the moment.
To OP's question though, are there real-world cases of blockchain tech being used for this, or is it more of a hypothetical?

The reason I ask is that the security of Blockchain comes at a cost (both in additional complexity and, for PoW at least, energy use). Have people who need those records in the real world found the additional tamper-proofness worth the cost?
I strongly suspect that the virus doesn't survive in vitro when exposed to a multitude of crystals! A sodium chloride crystal, for example.

Due to placebo effect you could probably even extract a "reduces symptoms" in a not very good human study too.

I don't disagree that you could setup a criteria which would admit masks and parachutes but deny crystals. But would it also deny all (or even almost all) other manner of 'obvious' snake oil past or future?
This is clearly a highly-technical project by teams at both Google and Apple, and presumably those teams have social overlap with the userbase here on Hacker News.

The risks raised by this article appear credible and worthy of consideration.

It'll be interesting to see whether Google and Apple do openly respond to any of the specific concerns raised by the privacy and security community - for exmaple, whether the functionality will be time-limited to the duration of COVID-19.

Google and Apple would gain huge potential leverage over nations worldwide if they retain the sole ability to offer and withdraw the functionality and to vet the applications that are allowed to use it.

Has any commenter here read the blog post? He starts from "network that evolves through simple rules" then goes on to derive how this results in space dimensionality, time, Sr, GR, the uncertainty principle, path integral, entanglement, and makes predictions along the way.

This is regardless of the specific rule that computes our universe. Also since that rule is Turing complete, it's going to be the same as every other Turing complete rule, and since we can't produce a machine IN the universe that can simulate the universe, it kinda doesn't matter what the rule is.

Everything in this article is completely illogical and baseless.

And we have to be fearful because this anonymous data is somehow going to be linked by Apple/Google to real persons and used for mass surveillance. But yet they could have done this for years without needing GACT as an excuse.

Intel and AMD refer to their systems as SoC since they integrated the north bridge (which includes the memory controller) into the chip, has nothing to do with Apple.

That's a weird definition. Most architectures don't have "I/O ports" and use memory-mapped I/O exclusively. And even if we read that as "any kind of I/O pins" and go back to the

Generally yes, except I seem to run into an annoying bug where if you start typing your password too quickly after the initial unlock keypress, the password input control sometimes decides to select everything you've managed to type so far when it initialises, so your next key press overwrites everything.
Plus at home I've kept the full lock screen because I actually like those random landscape pictures, but at work they've set the computers to directly boot into the password entry, which of course rather plays havoc with your muscle memory.

Fine up until the last cheap shot. None of those conflicts were wanted or started by the US. Saddam invaded Kuwait, the Taliban enabled 9/11, Assad provoked a civil war in Syria.

Disengaging always makes things worse. After the ‘Surge’ in Iraq the US tried to pull out and what happened? ISIS. The US pulled out of north Syria and our (talking broadly, I’m a Brit) allies the Kurds got massacred and thousands of ISIS prisoners got loose again. Walking away doesn’t work, we tried that with Afghanistan, just leaving it to the Taliban after the Soviets pulled out, and they came after us in New York anyway. It’s a small world whether we like it or not, and we’re in it together.
Yes I literally posted 5. The disentanglement of blockchain from cryptocurrency is senseless. The entire point of a blockchain is to serve as a distributed ledger. If it's truly decentralized, it has to be monetized somehow to incentivize the maintenance of the blockchain.

Hyperledger is a blockchain that is mainly used for these private blockchains that are used in corporate settings. However, a public chain has 100% uptime, is permissionless, and is by far the most useful application of the tech.

The strongest use case right now in the blockchain space is Bitcoin as a sovereign money. It's an asset with substantial liquidity that has incredible protections against asset seizure and strong independence against capital controls.

It's the type of thing that you go 30 years without needing it, but then when you do need it you really badly need it. Bitcoin does this well today and there are plenty of people who proactively plan for financial contingencies by holding some percentage of their portfolio in self-custodied Bitcoin.

We also have several examples (Greece a few years ago, Venezuela recently) of this playing out in favor of the prepared in the real world. When your country's financial system melts down, your Bitcoin holdings can give you liquidity and options despite everything else around you being completely disfunctional.
Right. They've done the exact same tracing for years as part of the "Find my phone" feature, but now it becomes problematic when it's used to mitigate a pandemic outbreak? That makes zero sense.

The problem here is that the ledger is public - and there exists few wholesalers who want their customers to learn who their suppliers are.

So the ledger must by design, anonymise each entity involved.

If you anonymise each entity, then every entity is Sybil.
