As far as I understand the point is supposed to be the blockchain is distributed trust. The longest chain = proof of most work = the truth. The only reason someone can't basically change the entire history of the blockchain is because no one has 51% control of the chain. The only reason no one has 51% control of the chain in bitcoin is because so many people are mining it to earn coins.

But, for medical records there is no such incentive. Therefore anyone can easily change the records or add new ones and claim everyone else who has a shorter chain has the wrong chain (which will be like no one since there is no incentive to mine).

So I'm probably just informed how blockchain is supposed to help here. Without the distributed trust there's no plus to blockchain. And without the incentive to mine that generates millions of miners there is way to have the distributed trust.

I'm happy to be wrong but I haven't see an explanation how this issue is solved for all these non virtual currency uses cases.
2) I'm guessing licensing comes into this, the same way netflix are the sole providers of certain content, and not others. Also I could technically watch something for free if I torrent it, but I'd much rather use netflix. In the same way, maybe this service is more about high quality and reliability,rather than the actual product.

3) I am as average as it gets, and I only upgrade every couple of years or so. They should definitely make this a yearly subscription model only.

4) They definitely have a second-hand market in poorer communities, who are willing to pay for older versions if they are cheaper. Old electronics are not completely useless and are way, way easier to repair than old cars.
I'm not sure why blockchain has become a perennial 'love to hate' favorite on a forum dedicated to 'disruptive' startups. The cynic in me would say the people complaining are the ones who sold their bitcoin for $100 back in the day and cannot stand the fact that they're out millions for not being forward-looking enough.

If that describes you, go invest in a new blockchain tech. There aren't actually that many -- most of the ICOs of the last year were for stuff built on the Ethereum network. Sort through that a bit and you'll find companies building entirely new blockchains, some of them incorporating very good, forward looking ideas.

Blockchain is still very young. You haven't missed out on anything. Do some homework. Invest.

But nothing useful has been built on a blockchain!

Go make something. You're smart. In the best traditions of the software industry it's almost entirely FOSS. Absolutely nothing stopping you from building something useful. And there's lots of funding available for those that do.

Saying blockchain is worthless is like saying public key cryptography is worthless. Before e-commerce it was sort of a novelty (the need for security was always there, sure). Now it's ubiquitous, as is e-commerce. The latter would not be possible without the former.

Even if the development is / remains purely driven by greed, the introduction of new financial markets and new investment vehicles means it's here to stay. There is zero chance this genie is going back in the bottle. Every day there are announcements about uptake by the finance industry and by governments.

But that's a shallow view of the possibilities. How about tamper-proof voting for governments? Nearly fee-less remittances? Un-censorable communication? Completely transparent non-profits? Trust-less provenance / chain of custody?

Let's be real. Humans are terrible to each other. Being to able to fight greed and corruption with a little math -- in a trust-less, incorruptible, self-sustaining way -- is potentially history changing.
Public keyservers are well-known, and in a different security domain than the download server. Without breaking in, a rogue party can't delete or replace keys from the keyservers.

I bet on the blockchain.

More and more people will eventually realise, as we can now witness by the facebook's revenue drop, that the fraudulent behaviour of the ad networks combined with the echo chamber does not bring them prosperity.

Which in the end would decrease trust of the consumer.

And bet who do we have there to trust? Well lets see... the blockchain? BINGO!

I would rather believe a friend of mine or a relative(related trust party) than corrupted ad network.

Now lets explain the corrupted.

If i pay more for the ad, my product will be advertised more, without the actual benefit for the consumer?

That is corruption.

So i would place my bet on the trust in the future.

Weird, there's something up with their Crowd Supply page. I saw the price there the other day (in the right hand panel that is currently empty):

I'm pretty sure most of the 23andme customers are in the US and not in the congo. By "many" women, you mean almost no women right?

> maybe the best outcome would be more open communication and understanding between couples rather than even more prescriptive social norms about how relationships should work.

Opening communication and understanding are the prescriptive social norm. You make it seem like cheating and rape is the norm. Also, most people agree on how relationships should work. That's how we got "prescriptive social norms".
Blockchain tech has yet to deliver on any of these promises. Instead we have a mass of people speculating that it might, someday, in future, do a load of stuff that will make it more valuable than it is today.

It's only like saying "cryptography is worthless" if it turns out actually to have worth in the long term. It could be a lot like saying the Sinclair C5 is worthless.

I don't see that the introduction of new financial products based purely on artificial scarcity does mean that it's here to stay. There are indeed announcements quite frequently - most of them turn out to be pretty meaningless, often overhyped by parties with a vested interest.

> How about tamper-proof voting for governments?

Any scheme that allows votes to be verified, allows people to subvert the process by demanding verification.

We have those. Cryptocurrencies make these worse, irreversible, uninsured etc.

> With enough political or legal pressure, you easily deploy a "51% attack" on the chain, and fork it as you like.

A 51% attack can do two things: Enable "double-spend" attacks - where the hash rate majority will ignore a block which was previoulsy mined and had a "confirmed" transaction, and instead mine from an older block which didn't have that transaction - but instead place a transaction paying themselves the money back. Anyone accepting payments over Bitcoin should use their common sense as to how many confirmations they should wait depending on the amount of money being transmitted. A 51% attack might eventually be able to write a chain longer than the current one, but it will take some time - and there is the chance that if it fails, the miner will have wasted his electricity costs.

The other attack a 51% hash power can perform is denial-of-service. They can ignore blocks containing transactions they do not want to include in the chain, and as long as they continue to mine the longer chain, those transactions will not succeed.

51% attacks can not change the rules of Bitcoin (although there are many people who wrongly believe this to be the case). If you try to change the rules, the rest of the network will reject your blocks and ignore you.

> what would stop a government from running the majority of blockchain nodes and gain consensus majority?

The costs, primarily. In the case that one party did accumulate a majority of hashing power, the network participants can agree to change the hashing algorithm to one which runs on commodity hardware. That would be many billions of dollars of specialized hardware equipment going down the drain, and will only make the system stronger by encouraging individual participation. Monero did this successfully, and plans to do it each 6 months to deter attempts to game their proof-of-work.

The cynic in me would say the people complaining are the ones who sold their bitcoin for $100 back in the day and cannot stand the fact that they're out millions for not being forward-looking enough.

I would say this attitude says more about you, and many others, in that you view bitcoin as a speculative asset rather than a stable currency to be used for the exchange of goods and services as initially advertised. This is not a positive argument for cryptocurrencies.
The annual releases are mostly cosmetic and typically only change higher-level details. They haven't made much in the way of substantive changes to the base system since 10.6. At the lower level, it's looking like abandonware.

How much has Windows and Linux changed during that time? I’m not going to read off the change log of everything that Apple has changed since 10.6

Apple is notoriously secretive. The "public announcement" of the new Mac Pro was a whole lot of nothing. Not one substantive detail. Am I supposed to wait until its 2019 release before making any commitment to support it?

So exactly what do you have to do to support the Mac Pro specifically? Of course they didn’t have any details. They hadn’t started on it st the time. But it still contradicts the narrative that where Apple is headed with the Mac is “unclear”.

It might be terrible, and there's no information about its specifications. "Waiting in hope" is no good for business and product planning.

I can give you hint. It’s going to be a multi core Intel chip. What are you thinking you need to do to support the Mac Pro specifically.

The hype train might work for phones, but for computer hardware it's a bit pathetic, and leaves me doubting they have a serious plan for it (as if the existing Mac Pro left us in any doubt at all).

Seeing they admitted they made a huge mistake with the current Mac Pro.

The merging of frameworks isn't of the slightest interest if you only develop for MacOS.

So the direction of the Mac APIs is of no interest to a Mac developer as is the fact that they are moving away from AppKit? Whether the fact they are merging the frameworks of IOS and MacOS are of interest to one random person on HN doesn’t mean their direction “isn’t clear”. The direction they are moving MacOS - the APIs is clear.

that they are
And the new chipsets aren't particularly noteworthy either; they are just details.

So first it’s not clear and now “just the details” don’t matter.

As a cross-platform software developer, I really couldn't care less. But I do care about their support for industry-standard APIs.

So you’re a “cross platform developer” and you’re overly concerned about the Mac Pro - a tiny sliver of a tiny sliver of the market. But you just said that you didn’t care about the merging of iOS and MacOS as a “Mac only developer”. A “cross platform developer” has much bigger issues than the graphic APIs unless you plan to do something like Electron and anyone should avoid those apps anyway.

Renault Sport, Porsche, SAAB and Nissan were doing great things with turbo charged cars in the 1980's, the implication of 'turbo' was clear and you could get 'Turbo' bicycle seats and even 'Turbo' sunglasses that embraced the concept. So it was a bit of brilliant thinking to name the clock speed button 'Turbo', it did what it said on the tin.

In the current era cars have more sophisticated interiors, often featuring a dial that enables the driver to choose between 'eco', 'comfort' and 'sport' settings. If you have got a long drive and you are paying the petrol then 'eco' might make sense, if you haven't got the wife and kids in the car and the boss is paying for the petrol then 'sport' might be the preferred setting.

We have all sat in front of laptops that whirr away even if we are just kicking back and reading Hacker News. We have all sat in front of laptops on some train journey where 'range anxiety' sets in and you fumble for screen brightness and other controls to extend the battery life. Yet we probably specified that super fast CPU with lots of RAM for compiling stuff or, heaven forbid, playing the odd game.

Wouldn't it be great if the Turbo button came back as a simple hardware switch that enabled you to easily switch up from 'eco' to 'comfort' to 'sport' modes? If you wanted a break from the fan noise then you could just slip into 'comfort' mode, then, when back to the grindstone with every second counting (due to the realities of project time keeping) you could step it up into 'sport' mode, knowing that fan noise won't disturb anyone in your open office? Back home you could then go back to 'comfort' mode with the fans only kicking in on compile, not because you have a gazillion tabs open.

So yes, I share your sentiment but I think the idea needs a reboot for the 2020's, by which time, as per the original 'Turbo' button the concept will be obsolete as we will all be using Intel 12th generation CPUs.

Unforunately no real information is available, the most recent update is the May progress report [0]. The 500 version is due for release before the standalone, and for the standalone they need to finish implementing the graphics/audio chipset in FPGA plus probably other design issues. Personally, I hope to see the 500 version available in 2019 and the standalone in 2020.

This topic brings up the issue of wrapping in Japan. Japan is notorious for having excessive wrapping. Individually wrapped cookies in a box with a plastic tray to hold each cookie. The bottom half of the box is sealed with a plastic tear off cover. The top of the box slides over. Then the entire box is wrapped in paper. If you purchase if they will then put it in a branded paper bag. If it's raining they will then put that paper bag in a plastic bag to protect it from the rain. That's 6 levels of wrapping.

It's a cultural thing AFAICT. Sure people speak out once in while but it seems unlikely to change without some major major concerted national PR effort against it, getting celebrities, politicians, etc all on board pushing for months or years and possibly even organizing boycotts until things change. But, if someone wants to do their part of make a small dent here well, here's a project you can try to take on.

The only reason those services use Twitter is because that's where all the people are. I'm not saying this isn't a beneficial use case, but Twitter isn't necessary for these kinds of services.

> I am constantly surprised by this point of view. Blockchain is a solution to a number of problems that were previously unsolvable, yet so much of the discourse is around the idea that decentralised trust doesn't really solve any useful problems.

Those two things aren't mutually exclusive. Blockchain solved some very interesting technical problems, much like a lot of advanced math might do. But as you pointed out, the discourse is around whether or not blockchain solved any useful problems, not just interesting problems.

Like others, I have yet to be convinced of a use case for which blockchain is the best solution (other than cryptocurrencies).
> We might find that our field could benefit from mining math related to mechanical and electrical engineering. Feedback and control theory, in particular, looks like it i could have some utility.

This was all over the place behind the core theme of my CS master's degree, for which I happened to also have background in both mechanical and electrical engineering. There are a lot of things that felt quite natural to me but that were proving elusive and challenging to people I worked with who lacked an equally diverse background by being exclusively focused on CS.

Two points I raised were designing with, leveraging, and modelling feedback loops in component-based software using control theory (application was on auto-adaptative AV streaming across a network of varying quality† but the overarching theme was largely generalisable); and modelling execution flow using laws from electrical engineering (using high level concepts such as power potential and current intensity as well as qualifying code paths as being resistive, capacitive, and inductive) as an alternative approach to complexity and optimisation.

The resistance to cross-domain mixing was surprisingly high, entrenched thought processes are a remarkably deceitful thing, even when faced with provable results.

† Something I would find out to be implemented a couple of years later with zero-delay Xbox Live movie streaming.
