> We are better off if each node, either biological or not, determines from provable and transparent facts ("this was agreed upon by 51%+ of trusted nodes")

In this hypothetical, what if the 51% of 'trusted' nodes conspired to lie? Also, I'm confused how the nodes would be 'trusted' if the system were truly 'trustless'—trusted by whom?

Do you not think that we would have to trust things that we don't understand? Even if I had in front of me all the transparent data about how a SpaceX rocket worked, I wouldn't be able to tell if it were true without relying on someone else I trusted to have more knowledge.

> I think we _could_ do make our gov't and officials completely transparent

Maybe I just see it differently, if something is completely transparent and I have all of the knowledge (and understand it), I wouldn't define that as 'trust' but rather 'knowledge' or something alike. For me, 'trust' has an inherent uncertainty to it, a doubt, where I choose to believe in spite of that doubt.

I trust that this message arrives to you the way that I send it, because I trust that Firefox is not tweaking the input, I trust my ISP is not injecting/removing text that I send, I trust that HN is showing you what I typed, etc. I have some idea based on how you're replying that those things happened, and yet I'm still trusting that it will work each time I send something, despite having not much idea how it works at each level.

> I think that Fake News is largely only able to propagate because there has been a failure in trust.

I agree that many people are trusting certain people/institutions less than in the past. I disagree that opaqueness is causing distrust, as I again believe that there is little if no 'trust' when things are completely transparent and known.

<counter hand-wave-y weirdo ranting about social trust :-D>

Personally, I think this has more to do with the cause:

> Trust is easily broken or exploited.

I think many of us have felt betrayed, ignored, cheated, lied to, abandoned, etc. Things have happened to us that have hurt us and made us feel afraid that people don't really care about us or actively are trying to hurt us. I do think this part can be changed. I think we can get better at apologizing, at forgiving, at mending our relationships.

I say this because I don't think truth is that connected to trust. I think if you tell me the truth (let's say truth = >99% of people believe it's true, as 'objective truth' can be really hard to pin down), and yet I don't trust you, then it doesn't matter if you tell me the truth or not, I will believe it's a falsehood. Conversely, if you tell me a falsehood and yet I trust you, then it doesn't matter if you tell me a falsehood or not, I will believe it's the truth.

From this perspective, trust is less about an 'objective truth' and more about one's personal subjective experience, often colored by the emotions one experiences based on different stimuli.

</counter hand-wave-y weirdo ranting about social trust>

Yes, I believe is easily broken or exploited. Do you believe it cannot be rebuilt?

I know nothing about nuclear energy but I immediately thought about the Tokamak. The article said it could be useful for scenarios where penetration of a wall of a device would be problematic. I thought I wonder if the Tokamak had the need to be sealed in some way and being able to send a signal inside it wirelessly would help. Maybe they need a completely sealed room but they also need to trigger a switch but no one can be in the room and typical communication can not penetrate it. You just need one bit to make it through to flip that switch from a 1 to a 0. This would be the perfect device. Ya I know that probably has no use for the Tokamak and I can’t think of a scenario where you need a completely sealed device with no holes but still need to send a signal inside. Like in the article they also mentioned submarine communications. You sound smart but surely if they could just do other forms of communication they would have already the US military budget is massive. Currently subs float a device to the surface so they can talk. The article says this slows them down and risks exposing them. Beside the couple mentioned in the article already I’m sure there has to be more use cases someone smarter then your or I can see.

> These vaccines are at best experimental - I'm not saying they don't work, but I am not confident enough in them to take the shot.

A drug that has been given 7.5 billion times is not experimental.

Crucially, the mRNA vaccines have a very similar effect on the body to previous vaccines. The fundamental mechanism is the same: stimulate an immune response to a particular pathogen without actually giving someone the pathogen.

> If your counter argument is that they have been tested and doctors and other professionals have stated that there is no way of adverse effects in the future, then why is everyone signing a release before taking the shot, freeing all parties of legal action?

I got my vaccine in the US and didn't sign a release to free anyone of legal action.

Also, the way we know that it won't have adverse effects in the future is that the vaccine doesn't persist in your system. If it's going to harm you, the harm will be in the short term. It can't just pop up again in 6 months.

You shouldn't take my word for it. Do your own research[1], as they say.

For anyone interested in e-bikes, that has a do it yourself attitude, I recommend looking at Grin Technologies in Vancouver.

Lotta weasel words in there, maybe describe how you acquired these loosely held "beliefs?"

What Is Imax Enhanced, and Should You Care?
I love the idea of e-bikes and would love to be able to use them and not need a car (which i don't own), but i just don't feel safe using them in US cities... NYC has too much traffic, SF has too many hills, Seattle is too wet.

I wish there was more alt-transit for commuter scale transportation to get around without a car, but the autonomy of not using a bus. Scooters seem promising but they're a pain on the roads (with laws banning use on sidewalks), and i've heard horror stories of how unsafe they were.

I feel like the ideal form factor is a pallet dolly: You have a handle, its wide so its comfortable to stand without balancing, and you can ride in the road confident a car can see you and not run you off.
Not really. Many of them just use simple WiFi APIs and already work with the quest. It's very hard to block this if you allow internet access to an app.

Example: https://www.handyfeeling.com which you can use with the sexlikereal app. It connects to your WiFi on its own and has a cloud service.

I don't really understand why they'd want to ban this kind of stuff. Let people have their harmless fun. Why does everything have to be kid friendly? Some people don't even have kids. Just put it behind an age check or something. Just like violent games which are on the platform.

The true risk of leveraged ETF's like TQQQ is not so much the risk of large losses in a downturn, but rather that under extreme market conditions the fundamental mechanism that powers the ETF will break down in some unexpected way.

These leveraged funds are made up of complex derivatives, if the funds counterparties (UBS, Goldman, Societe Generale etc.) are unable to make good on their existing trades with proshares, or refuses to allow proshares to open new derivative positions it spells trouble for TQQQ and other leveraged ETF's.

In a 2008 style scenario funds like TQQQ would be hit particularly hard by 1. leveraged exposure to crashing markets and 2. bankrupt counterparties going bad on TQQQ's swaps.

> Instead of posting customer hashes to a public digital ledger, Surety creates a unique hash value of all the new seals added to the database each week and publishes this hash value in the New York Times. The hash is placed in a small ad in the Times classified section under the heading “Notices & Lost and Found” and has appeared once a week since 1995.

> Surety’s main product is called “AbsoluteProof” that acts as a cryptographically secure seal on digital documents. Its basic mechanism is the same described in Haber and Stornetta’s original paper. Clients use Surety’s AbsoluteProof software to create a hash of a digital document, which is then sent to Surety’s servers where it is timestamped to create a seal. This seal is a cryptographically secure unique identifier that is then returned to the software program to be stored for the customer.

> At the same time, a copy of that seal and every other seal created by Surety’s customers is sent to the AbsoluteProof “universal registry database,” which is a “hash-chain” composed entirely of Surety customer seals. This creates an immutable record of all the Surety seals ever produced, so that it is impossible for the company or any malicious actor to modify a seal. But it leaves out an important part of the blockchain equation: Trustlessness. How can anyone trust that Surety’s internal records are legit?

Oversimplifications like this are not helpful. There are a ton of ways that complex numbers are interesting, and they have important generalizations as e.g. an even subalgebra of G^2 (leading to quaternions as the even subalgebra of G^3, and so on). They’re not just “a circle”.

> EDIT: I would also say the lie that we live in a 3+1D world (X, Y, Z + Time), helps confuse the mater. We probably live in a 6D + 1 world: X, Y, Z, Pitch, Yaw, Roll, and Time.

If your model doesn’t treat time the same way as space up to the metric tensor, it’s probably not very well generalized. There should be an even number of parameters.

Rotation including the time dimension is just acceleration. The math is simpler if you’re in a ++++ metric - rotations are a bit weird in +++- because rotations into the time dimension are hyperbolic. I suggest reading Dichronauts, a book covering a ++-- tensor.

You’re worried about vaccinated people being in danger of the thing they’re vaccinated against. Either they work or they don’t.
Much lighter. The difference is quite a lot more than you might guess from the raw numbers, because the LH2 doesn't need to loft the weight of the jet fuel, but only its own, lesser weight.

Since it doesn't need to loft that weight, that lifting capacity can be used for cargo instead, thus also increasing the top-line income for performing the flight. Finally, locally produced LH2 will be cheaper per joule delivered than jet fuel, moreso after its carbon is taxed, and the carbon burned in transporting it to the airport.

It will take a while to get there, because it needs both new (or maybe retrofitted?) airframes, and new airport infrastructure, initially only at key international airports.

Not injecting CO2 directly into the stratosphere will be a side benefit.

You can always come up with a million reasons not to do something. Plenty of people bike safely in NYC, SF, and Seattle.

You don’t have to wish for an alt-transit solution that’s not a bus. Bikes exist. The more people who ride them the safer and more normalized they get.

I’ve bicycled (conservatively) 7,5000 or so urban/downtown miles over the past decade or so in Portland, OR. I get wet, I get sweaty, I get tired, I get into the occasional close call with cars, I get scared.

My biggest tips are: don’t buy a bunch of gear at once. Buy 1 thing at a time once you figure out what you might like. Ride slower, it’s not a race. If you get too scared, pull of the road, walk your bike, and take a break — I still do it even after a decade of riding.
This is really neat, I'd never heard of the Wilson score.

Some other thoughts - anyone know what state of the art is in ratings?

- especially for technology products, time on market seems like a big thing. How should the iPhone 8 be rated today? It was a great product in its day, but if someone is looking at it now there are a lot more trade offs.

- I wonder how we should consider the users in this. It seems like certain users are more harsh or fair than others, and have different rating patterns. Should we try to identify "good" reviewers?

- Similar to the above, I wonder if for example Uber drivers get harsher reviews if traffic or weather is bad. So should we normalize for local trends in ratings?

> The prospect of cities with much less air pollution is wonderful.

For cities with a dense urban core (of which mine, Philly, certainly is) I'm really hoping we lean in on bikes (electric or not) moreso than electric cars. Even less carbon-intensive to produce, and in a city with this level of density it's shocking how quickly you can get around by bike. I would go so far as to say it's often faster than driving if you consider the time you spend looking for parking.

It's just that with our current car-centric infrastructure, it's way too dangerous.

Plus with some e-bikes, you can detach the battery and carry it with you indoors to charge it back up. Try that with an electric car!
