Web3 replaces storing things on webservices which are run by companies like Facebook or Twitter with storing things on blockchains.

So yes, it is a crypto thing in the sense that it uses blockchain technology as the storage medium (sortof). You still need somewhere to store the data, but you can put pointers to those storage locations on chain.

Web2: Twitter knows the URL to your avatar and decided what it is (usually they listen to you).

Web3: The blockchain knows the URL to your avatar. You decide what it is and nobody can (practically) stop you.
Agreed they have no choice. But this race to the bottom has only losers, in the end companies should just pay their taxes and the UK facilitating this is not going to make any friends. The channel islands was bad enough.
My only realistic chance at employment is programming. I don't have the endurance for a day job, due to long Covid.

> Harm OCD is a subset of classic obsessive compulsive disorder (OCD). The condition is characterized by having aggressive, intrusive thoughts of doing violence to someone, as well as the responses the person uses to cope with these thoughts... OCD makes the individual feel that they can’t trust their own mind. Wherein someone without OCD could have a violent thought and recognize that it is simply a thought, a person with OCD who has the Harm OCD subset worries that just having the thought is somehow meaningful.

Most revolutionary/generational tech has started with an implementation or at least a proof of concept of something new and novel that subsequently drove interest in how it worked. Like Google Maps use of AJAX for infinite scrolling or Napster and peer to peer networks, or even Bitcoin and blockchain. I’m not aware of any such example for Web3.

The whole design of bitcoin was to make it difficult or impossible for governments to stop it existing. If you were the head of some government how would you do that? It's open source software that can be run on pretty much any computer in the world.
I don't think it's the answer you're looking for, but it's basically how I think about the scientific process: we ask all the wrong questions when we have the wrong mental models and the wrong vocabulary. But as our understanding improves, and as our vocabulary begins to map to the real world better, we start asking better questions and this unblocks science from progressing.
Ohh since when is that? I've never seen or used that syntax and I sort of like it.

Before it went insane, the UK played a positive antagonistic (to Germany) role, that I believe helped shaping some European institutions.

The EU is in some way weaker, because it lost a very important state, in some way stronger because everybody can see the shitshow that Brexit is and nobody dares to propose Italy or France leave the Union.

The UK is definitely weaker.

But how can that be a limiting factor as long as the sum of power delivered to all ports is <=120W and the power delivered per port is less than what the rail for this port is capable of delivering?

Why can't I charge devices on all ports with the power distributed like 65W, 30W, 20W, 5W for example?

NGST started in 1996! I was a 6th grader, at that time! I was fortunate to wake up at 2AM PT so I got to watch the entire webcast. I’m so happy it made it up and they unfurled the solar panel early — I wonder if that was a way to say goodbye while on camera.
I hesitated with the word choice but when i say "modern" i mean that the project dispenses with the implementation details of BBSes that are not relevant to the "BBS experience", such as the use of telnet/ssh, outdated text encodings, and long signup forms asking for copious amounts of personal info. I think adding images/videos would definitely affect the experience.
Seems like a reasonable avenue.. but it must be skewed by multiple devices (work+personal phone, phone+tablet+laptop each with a SIM - them being the same account isn't particularly relevant), and presumably it was `anonymize(SELECT * FROM active_sims)`.. including visitors and anyone else on the networks, which would also include children.
There's an awful lot of people looking from the outside of the UK in telling people that brexit is going terribly when honest to god nearly all focus in the UK has been on covid for 2 years with a short blip during when we actually left. Few people really talk about brexit anymore in the way we did in the years prior.

It happened, the world didn't end, economic armageddon didn't occur, mostly people are over it and more concerned by covid as I said.
> but on the other hand aren't there a lot of decentralized resources, made or to be made, that don't require crypto or blockchain at all?

Absolutely. In the project I linked to, I'm using DHT and torrent protocols to deliver decentralization.

That said, we run into an issue in a decentralized system called Zooko's trilemma [1] when it comes to naming. Names need to be human readable, secure and decentralized. Using public keys, this isn't made possible.

> Often in W3 discussions there seems to be a push to find a way to use crypto rather than an explanation of a resource, period. If a decentralized product includes blockchain or crypto, I'm immediately skeptical and expect a good explanation for why the product can't exist without it. Usually it seems like the product doesn't need it or could be built on some other option.

In the case here, I opted to use the handshake naming protocol. Handshake's use case makes sense as decentralized networks are subject to sybil attack [1], so a free for all naming system doesn't make sense. Handshake is one of the blockchain projects I admire specifically because the blockchain project solves a problem that has limited the success of decentralized systems until now, and the purpose of the coin is to limit the ability for an attacker to take over all the names.

> I'm all for decentralized and federated solutions, but they do tend to be slower and more resource-intensive. Blockchain most of all.

I think this depends on the functionality. In the case of the handshake blockchain, lookups are faster since data is local. On the other hand, you're absolutely right as DHT is very laggy.

The biggest car we own is a Honda CR-V, but if I had to tow a boat 3+ times a year or carry sheet goods once a month, I’d buy a truck appropriate for that and drive it the other 350-ish days of the year. It’s not practical to rent a truck every month or for a week at a time just to save a little money every month. Are there trucks sold that never do a single truck thing in their life? Probably, but probably not as many as you’d expect.
I switched from Scala because I found the interior to be so good. Calling Java from kotlin is easy, and - unlike Scalia - the inverse is also true.

> I don’t think any political entity has any interest in controlling what individuals post on a tiny website like HN.

I wish I could pull a cached view of the comment up (I tried), there wasn't anything I would interpret as being inflammatory in there.

The comment boiled down to:

"VICE isn't what I'd call the most reputable/unbiased source. I'd encourage everyone to do their own research/make their own decision. Here are a bunch of links of people walking around the same area, and it looks nothing like what is cut together from that VICE episode."

The speed at which it was flagged and removed was shocking. Like I said, (maybe I am a bad person for this), I don't really care that much about China or politics in general. There are a lot of other things I'd rather spend my energy caring about, that directly impact me.

I just wanted to call out this very odd behavior. I don't see HN as a place where people who speak objectively + respectfully get silenced, generally.
My personal running definition is something like: "The Web3 vision is that by leveraging publicly distributed, trustless cryptography, a contract and payment system can be tightly coupled to services, thus enabling truly decentralized coordination, execution, and delivery."... it's pretty dry.

You can't find what you are passionate about, it's not something that gets discovered. You pick it and hone it. Getting experienced, acknowledged by peers, and executing from knowledge all come with time and dedication and you become passionate as you want to drive that thing forward.

buying a stock on web2 vs web3 gives interesting properties because of ownership.

Totally tangential to the main point, but is no-one going to comment on the fact that the colour spectrum actually does in fact go from less-something to more-something? It's a spectrum of light frequency.

The colour labels, like "blue" or "red" are a psycho-cultural construct that are in large part shaped by the cone receptors in our eyes, but it's still a spectrum of light frequency.
Or just depopulate regions in the world which require heating to survive.

To reiterate, I'm not saying there's malicious intent in any single bug. Yes, billing errors don't lead to more revenue for the firm. I'm describing rather a systemic bias in incentives for the people doing the work (programmers) and supervising the work (managers).
I understand repr for debugging (though imo it's a deficiency of the language that custom objects don't have a repr which lists their attributes), but eq is a property of the domain itself; two objects are only equal if it makes sense in the domain logic for them to be equal, and in many cases that equality is more or less complicated than attribute equality.

In 2017, only about 15% of vehicle trips in the US were taken for commuting [1], the rest are for shopping/errands (45%) and for socializing/recreation (the balance). So even if we eliminate half the commute trips, we still have a long way to go to reduce the miles traveled.

Getting fusion to happen is the easy part.

Building a reactor that is economical is not so easy.

Fast neutrons, tritium management, corrosive molten salts, beryllium supply constraints…whole lotta material science problems you gotta work out at scale and on budget.
I think 1) will probably never get "solved," but that's ok. I don't think the vision of DAOs replacing traditional companies will ever materialize, for example. It's just too inefficient.

What I see blockchains enabling (to what degree, tbd) is ownership of digital assets without a central party. Take concert tickets, for example. Imagine a world where transaction fees are nominal and blockchains are scalable. An artist/venue can mint tickets and have people buy them directly from them, no TicketMaster with 20% "convenience" fees needed. Now, of course, there will exist a product (probably a winner takes-all, as usual), that will serve as the UI to mint the tickets. But a significant value add of such products, the validation of tickets via the authority of their name, will be replaced by the blockchain. I don't know exactly what that'll look like, but I don't think that's insignificant.
There is way less crime in Cabo than in most of the US.

Near term - yes, long term you want to use those rockets to put the people, factories and general infra in place to build the really massive telescopes, in the hundred meter to kilometer size categories.

Not to mention crazy long range VLBI radio setups or telescopes at the edge of the solar system using the gravity lensing of the Sun to observe things.
So no ansi animations then?
It's forward progress, but nowhere near being useful.

By "more energy out than they put in", they mean passing "theoretical breakeven", generating more energy as heat than they put in as electricity. Not converting that energy back to electricity and making the thing self-powered. Brief periods of theoretical breakeven have been achieved before.

Ahead lies "sustained theoretical breakeven" - the thing can be kept running for a while. So far, other tokomak experiments have achieved 70 seconds of plasma containment (Korea) and 120 seconds (China). That's below ignition temperature, though. Then "self-sustaining breakeven" - the thing can power itself. Then, someday, "economic break-even" - it can pay for itself. Then, maybe, useful power generation.

There's the problem of getting the energy out in some useful form. This begins with the "first wall" problem of finding something that can survive the conditions just outside the magnetic field. Those conditions include huge numbers of neutrons, which tend to split atoms in the first wall material and cause unwanted transmutation. This causes radiation embrittlement, which is not good for materials.

It's going to be a long haul.

I have one thing that gives me a deep sense of fulfillment and a feeling that I was not living those few hours of my life in vain. That is writing fiction.

paradoxically (or maybe not) it is not as rewarding process-wise as writing software, which has the strongest instant gratification loop after, maybe, video games.

You can’t really be a writer, however, unless you want to die in poverty, etc.
The article doesn't really go into detail about this (it's mentioned in the video) but the key breakthrough they're referring to is increasing the magnetic field strength from HTS (high-temperature superconducting) magnets to 20 Tesla [1].

It's hard not to come away from reading any of this without thinking what a huge boondoggle ITER was and is and there was plenty of reason to think that before now.

A lot of talk here is given to net energy production. That is a key milestone but it's not by itself sufficient for commercial fusion power production.

Example: imagine a plant costs $10B and products 100MW of net power. It has a lifespan of 30 years and requires $500m/year in maintenance and staffing. That capital cost and operating costs need to be amortized over the lifespan of the plant so even though it's 100MW of net power production, those numbers simply aren't commercially viable.

I applaud these efforts but I remain skeptical on when (if ever) we'll have commercial fusion power production, for several reasons:

1. The issues of turbulence with a super-heated plasma;

2. Power loss through neutrons; and

3. Damage caused by neutron embrittlement of the reactor itself.

Personally I think solar is still the frontrunner for the first renewable mass-scale power production method that will be cheaper than fossil fuels and thus replace fossil fuel plants for economic reasons.

I'm glad there are a bunch of commercial enterprises focused on this. I hope at least some of them explore some of the alternative forms of fusion (ie other than hydrogen). For example: proton-Born fusion [2]. Aneutronic fusion would have huge advantages.

As suggested, the core ethos of web 3.0 is truly decentralisation.

Decentralisation of internet was there since the very start of the World Wide Web.

The first internet during era of ARPANET was decentralised and it evolved into giant monolithic cloud to to appease the economies of scale.

In recent times, we have seen a lot of limitations and vulnerabilities of our dependence on the cloud counting from data breaches, hacks to outages. But since Cloud has become a single point of failure.

There are tens of billions of devices on earth having capabilities far exceeding the Great Cloud, yet they are completely wasted because we insist on using the data-centers to do everything.

It is high time that we realize the ceiling and limitations of the Great Cloud and move towards a decentralized cloud where the devices in our hands are the powerhouses.
Which is odd because Github doesn't use Teams, they're Slack based. As in, if I set up a meeting with my Github counterparts they're late because they had to install Teams.

High-performance networking somewhat excludes mobile and cloud.

Regardless, the io_uring interface, which is general-purpose and still based on file descriptors for its initialization, does go out of its way to work around some of the problems with the socket model.

>This “protein-folding problem,” as it came to be known, baffled scientists until this year, when the papers we’ve deemed the 2021 Breakthrough of the Year were published.

This is a straight lie and the author should be embarrassed. There's not one scientist alive that can explain how proteins fold from their amino acid sequence. There's not one algorithm in existence that can predict it de novo.

I'm so tired of seeing this lie repeated over and over. AlphaFold did not gain us any new information on how proteins fold. It just got really good at modelling them from existing data where existing data is available. Which is great. But still ultimately limited by the same categorical limitations of homology modeling. It simply has not solved protein folding.

Yes it's amazing.

Yes it's worthy of lots of praise.

No, it did not solve protein folding, ESPECIALLY in the way that is described here.
That's why not giving them ability to copy data, allow them to use that data only on your device and send aggregated information back. So they cannot copy the data
