We do something similar at our startup. Basically we're a communication tool for construction, maintenance work and visitor management. Our selling point is simply data consistency, e.g. you can't edit posts, unlike on Facebook, and deleting will give a notice. Photos taken from the app are signed and location stamped. I think it's interesting that people comment you can just take a photo of an odometer, but that's not something that two parties do all the time; it's best to just automate that process.

Blockchain is not a "killer" feature of the app, but it's another layer of security. Databases are the core, but staff with access can edit a database in seconds. Maybe one way to think of it is like cash registers. The person operating a cash register can still steal it, but it's a lot harder than if it were just a box. It won't stop a dedicated person, but will greatly discourage doing it casually.
Just because "the majority" want it doesn't make it a good thing. That's why there is a Constitution (in the USA) and courts to protect various minority from the over-reaching majority. If I make a few bucks on the side working for uber in the evenings does that mean they should give me an insurance policy and retirement plan?
And it’s sensitive to moisture! And requires power! And probably software updates. And at some point, it’ll start selling your data and showing you ads. And then one day the manufacturer will brick it remotely because they don’t want to support it anymore, even though it was still working.
Inventory management. In many cases you want this centralized so you can manage it. But the reason is really so you have a “record” of what is in storage. The blockchain keeps it decentralized (ie less risk of a user deleting it), at the same time anyone can query the inventory.

Not directly related to this case but today I wanted to open a PDF as part of a insolvency case I am watching and when I opened that PDF in the embedded browser pdf reader it just displayed something like "Open in Adobe Reader for the best PDF experience" with a link to download Adobe Reader. And of course - Linux is still not among the supported platforms. So I was unable to open this PDF. Great company...
Serious question, why is this a joke? Couldn't javascript be just another language to replace bash?
"Secured by hard crypto" is item fifteen on someone's priority list after usability, cost, reliability, speed and the font used on the marketing page. Note that none of the questions you raise are answered by protecting a jpeg with hard crypto... (If that was the point, my apologies for re-explaining it).
I feel like I have some kind of mathematics dyslexia. I can understand all the concepts, but I find formal mathematical notation almost completely incomprehensible. Expressions with all kinds of strange symbols, often variables introduced that are either completely undefined or defined ad hoc locations remote from the usage, integrals and sums with no subscripts / unclear scoping, etc etc. Clearly other people just read these and I even know people who will ignore all the text in a paper and just look for the equations. I wish I could master it because in some areas it is a genuine barrier to me achieving my goals.
To some extent, I suppose so.

On the other hand, if you prize data collection or centralization, you must make some trade offs, including increasing some friction, as well.

The less you seek to control your users, the better their experience can be.

A tiny anecdote, with Jitsi Meet you can send a link to a meeting, someone who’s never used it before can click it, and they’re there. No need to set up or be logged into any account, install an application, or even find a small web client link at the bottom of what’s more or less a malware ad.
Blockchain as a data-structure gives you tamper-evident, append only database.

Blockchain as a system (datastructure + PoW) solves consensus & trust between agents in a trust-less and censorship-resistant way (without introducing a trusted party).
It's such a shame for profit companies abuse computers and computer users this way. Some of these ideas are really cool and could make people's lives better but they get given a terrible name. We're quickly reaching the point where the general public is becoming very afraid of technology.
A construction worker friend was working about 40 feet up on an extension ladder when the base went out. He said the hard part was resisting the urge to jump off, but they had been taught (correctly) that all jumping will do is increase the rate of falling. He rode it to the ground and was ok.
A more useful starting point for comparison might be the projects' respective stated goals. This is the first one listed for QuickJS:

Small and easily embeddable: just a few C files, no external dependency

Whereas v8's project description opens with:

V8 is Google’s open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome [...]

The stuff in the video is definitely super interesting but much of it is about how design goals in v8 are met.
It seems that the CCP admit the goal of forced assimilation. We might even say that their goal is an ethnocide. But calling it a genocide is using a definition of the term that is controversial (and not accepted by a majority of scholars). The core of the debate is on what "intent to destroy" means:

"The specific intent element defines the purpose of committing the acts: "to destroy in whole or in part, a national, ethnical, racial or religious group, as such". The specific intent is a core factor distinguishing genocide from other international crimes, such as war crimes or crimes against humanity.

In 2007, the European Court of Human Rights (ECHR) noted in its judgement on Jorgic v. Germany case that, in 1992, the majority of legal scholars took the narrow view that "intent to destroy" in the CPPCG meant the intended physical-biological destruction of the protected group, and that this was still the majority opinion. But the ECHR also noted that a minority took a broader view, and did not consider biological-physical destruction to be necessary, as the intent to destroy a national, racial, religious or ethnic group was enough to qualify as genocide.[29]"

There's no pleasing some people.

Never mind that Livecode IDE runs on Linux, Mac and Windows it also can produce compiled apps that run on those 3 platforms and iOS and Androd and even as a webapp like PHP. And it can even compile to HTML5 (although that's more limited).

It works with version control and unicode, it has regex, cryptography, sockets, JSON, XML, OAuth2, SVG etc. It has database libraries for interacting with sqlite, postgresql, mysql, etc. It can incorporate a web browser and control that using Javascript and callbacks. It can be extended to integrate with Java, Objective-C, etc. You can create your own GUI widgets. And it's free.

But that's still too much like Hypercard, which only ran on an ancient Mac and nothing else. Hypercard could do about 10% of what Livecode can do. And Hypercard has been dead since before you touched an IDE.

No it's not. First off he's not advocating genocide and second off you need proof that genocide is happening before you can make such a serious accusation.

You're telling me that a holocaust level genocide is happening in China right now? Serious accusations require serious evidence. Prove it. Something like pictures of mass graves like the ones you've seen in the holocaust or the rape of nanking is sufficient for me to do a complete 180.

What's going on here is mob mentality and you're part of it.
I would argue that scarcity doesn't matter if you have sufficient trust. It's probably fair to say that the majority of global financial transactions are digital. Practically speaking, there's not much stopping any of those institutions from incrementing a few bits here and there, except for trust. The illusion of scarcity matters, but can be maintained with trust.
I have not seen a single defense of this behavior in this thread except those with the thesis of "but America".
Alternative interpretation: person is looking at the data in the app while brushing.

Of course, it could also be a replacement mirror, but given that there are tiles drawn next to it and the phone holder is a suction cup on what vaguely looks like it might be a mirror, I doubt the phone is meant to be a mirror. Or am I missing the point here and is the message simply that one should be looking in the mirror rather than their phone while brushing teeth?

This seems like a currency use case unless you're verifying non-crypto payment in which case I'm not sure how I follow verifying an anonymous ticket holder signing a blockchain as any evidence of verification of real payment to a real winner.
No doubt, many taxi drivers have been getting screwed over by the current and pre-ride-sharing state of the industry.

I'm a big believer in incentives and how they influence behavior.

For better or worse, ride sharing systems have put drivers in a situation where they have to provide amazing customer service, and due to supply pressures, the price has been falling to levels that make it difficult to make a living.

Before ride-sharing came along, cities had set the rates to protect customers from being gouged. I think they can safely remove the ceiling now. They may have to set a minimum per-mile rate to protect drivers now (if they aren't doing already doing so).
> any given vector of the space can be represented using a linear combination of a finite subset of the basis elements with rational scalar coefficients?

FWIW, this is definitely false:

x = q₀·√2/1 + q₁·√3/3 + q₂·√5/9 + q₃·√7/27 + q₄·√11/81 + ... = Σᵢ(qᵢ·√πᵢ/3ⁱ)

for rational qᵢ.

Edit: primes approximate e^i, so 2^i isn't large enough.
Two things:

1) you'd still budget 125k a man-year? Why? That's only needed for devs in SV, NYC, London and other places with mad rent, besides - all you're gonna get in these places are fresh university grads and hipsters, not seasoned people with actual experience that tells them to not use a two months old JS framework for something that is supposed to live long.

2) Why limit it to USA? Other countries have decent programmers too, with way lower cost of employment. 60k is going to fetch you quality in Germany, 30k in Eastern Europe.

Besides, the best way to finance all of this, other than pressuring government to procure only/preferred open source is some rich startup exiter putting a couple billion dollars into some sort of trust fund and pay the development from the interest.
Added both. Thanks again!
The ROM on most modern ECUs is cryptographicly protected isn't it? (I know it is on my 2006 Toyota Carola because I've looked at replacing it.)

It would require cooperation from auto manufacturers but I'm sure you could come up with a scheme where the car itself signs and timestamps mileage data.
Maybe next year Trump will break up my gay marriage and make it illegal for me to get the medicine I'm on. Nothing like a little down-home American human rights abuses. He can't even condemn a terrorist group when asked directly to.
You're arguing against a straw man. I never said that polls are always wrong. My political desires don't hinge on the current polls being wrong.

I'm simply asking a question about whether the pollsters have corrected their methodologies. There was clearly something wrong in 2016 when they repeatedly failed to predict the GOP primaries and failed to predict swing states and even some states that weren't considered swing states in the general election.

You're right that I haven't read the analysis that you say exists. That's why I'm asking for it. Which pollsters have done the reweighting on their 2016 data and shown that they then align with reality?
I am suggesting that you keep bringing up risk management out of nowhere while I try to teach you how laws work.
I've been hoarding significant YouTube channels for years, at a cost of many terabytes of HDD space. Even though they were always available for free, I was always betting on the fact that YouTube's status as being incredibly easy to archive would not last forever.

I feel vindicated, but also sad that the end of this particular era has finally arrived :(

I agree that if you are doing a one off that nobody is likely to care about until some much later date it's probably worth while to OP_RETURN some proof on Bitcoin or something like that as it would be less ambiguous to prove that you knew something at that point. On the other hand you could encode whatever you like in some field of a fake PGP key and upload that to key servers.. and at the same time post it here in HN in a comment and tweet it, and that's really good enough to satisfy almost everyone as it is. There's just so many ways to get arbitrary data written into logs that can be used as evidence later. We're already drowning in distributed systems that log our every move.

For anything that involves timestamping some assertion that many parties care about on an ongoing basis it's much cheaper to have a distributed system of watchers. See certificate transparency. There's a lot of commercial inventive to want to falsify that, but is anyone able to in practice? There's no blockchain there.
Okay but how does this relate to the topic? Could you swap this product for the one you currently use for the second point, is that what you're saying? You seem to be advertising for a Google alternative in a thread about encrypted open source photo storage? I'm confused.
Russia, China and Saudi Arabia are not friends. Why would they ever pair militarily is beyond my comprehension. Saudi Arabia is armed by the west btw.

As for EU vs Russia - you really think the EU is that suicidal? It would be nuked into oblivion in a matter of minutes.

As for water. Two of thee largest nuke holders are the US and Russia. The US has Canada whth the largest reserves of water. Russia has plenty of it as well. So you think either is going to be attacked by any country for water?
You don't even need git for this, just diff is probably enough.
What kind of inventory receives benefit from this though? The users still have to trust whatever the group that maintains the inventory says is being added and the group that maintains the inventory can already expose what's in their inventory to whoever they want without making it a blockchain.

I can't figure out who this manual is written for. TileCode and the example games appear to target programming beginners and even children, but the lingo here is unlikely to be comprehensible to anyone but CS majors. And it's not like they're describing a complex idea here, it's just the language they use to describe it seems almost willfully arcane.
How about, most the stories of what's happening in Xinjiang might not actually be true?

So thegrayzone called rightly about the Bolivian coup to be orchestrated by the US with the MSM all agreeing with the US talking point of the Bolivian 2019 election being fraudulent. However, the recent election from last week prove all MSM basically being the mouthpiece of the US's war propaganda machine.

I should correct this. MD stands for "Message Digest" which is what this type of algorithm is for. So then it's just a coincidence that it's also the initials of (Ralph) Merkle and (Ivan) Damgård whose method for making a cryptographic hash out of a compression function was used.
The only thing that brings me solace in regards to doomsday scenarios like this is that they're extremely unlikely because of human incompetence.

We are so far away from companies creating and embedding computers everywhere for this to be an issue. Let alone for sophisticated means of interaction.

And lets say we somehow exceed all expectations and companies start creating marvelous products that are all on par with the iphone. It's still going to be difficult for them. There are people out there that are afraid of 5g because they think it causes coronavirus. We've avoided capitalizing on nuclear energy because of NIMBY. These nutjobs combined with perpetually on the fence observers will be a big enough stumbling block for a lot of this overreaching behavior. Remember how places banned google glasses?

Have faith in human stupidity and disorder - it's a tried and true system.
I have not, and it isn't plagiarized - but I'm not the only person that has similar views, so it is quite possible to have the same basic theme.
Yeah, we spent over $10,000 (US) on chemo for one of ours. It takes a lot.
More interesting IMO are securities in etherium. The world does just fine with (for example) the options clearing corporation and courts, but I wonder if by automating it you could fix some of the scaling problems (for example, allowing people on short visas to use options in foreign markets.)

It is an interesting point. When you first learn words in your mother tongue, you don't do it by outside reference to another language. Why is it different for you when learning a second language?

That's a very good idea, until you realize how specialized the modern city is. How many people does a single supermarket serve? How many a bakery, dentist, bicycle shop, etc.? Walkable means about 2-3km away, and that's not as the crow flies. If you really want that kind of city, you end up with something pretty dense. Personally I would prefer a tad more space.
Some people use their cellphone as a pocket mirror to apply make-up in a pinch. So we're there already.
I'm not American so the US-China rivalry comment is not relevant to me. If my family was killed by a bombing attack I would want to get to the bottom of why it happened in the first place without just blaming an entire population and justifying their genocide.

I am not saying that jihadist extremism is not to blame. But I don't think an entire Uighur culture is to blame either and especially not Uighur people who are being victimised.

>I'm not saying either side was right. I'm saying it's wrong to comment on how this is disgusting.

It's not wrong at all to comment on this. What the Chinese govt is doing is plain disgusting and they should be held accountable just like anybody who is supporting them. We hold extremist groups who carry out attacks responsible, so why not a racist, genocidal govt who instigated the whole thing anyway?

What's the point of a comment like this? Do you really think parent doesn't know that this is a niche interest? Custom integrations etc basically always are only done by a very small number of people, used by a lot larger (but typically still small number), that doesn't make them worthless. There's even an obvious example in the same niche, see the ecosystem around what was the Logitech squeezebox.
Can’t see it behind all the pop ups.
Maybe instead of an image, both parties could use an ODB reader that signs the mileage cryptographically, and pushes it to the blockchain?

This way both parties could verify the transaction was completed as contracted (IE no joyrides).

I'm still in the camp this probably doesn't need blockchain, but that would at least handle the image manipulation problem.
Disagree. Code is leverage, and leveraging valuable property is a great passtime, and smart for people in tech.
