> How is this not just the exact same formula?

I think it's actually a much more interesting formula because

(1) this stuff was invented out of whole cloth - concepts like MEV bots, hoping normies don't notice the rugpulls in progress, inventing stablecoins, staking, and establishing borrow rates are all unique to decentralized finance and involve strangers paying money in order to be entertained and maybe earn some of other strangers' money

(2) even though it was built entirely from scratch, the concepts and language end up looking EXACTLY like some of the synthetic constructs we see in "traditional finance", which I thought were actually based on something of real value

So -- watching my Twitter feed with the contributions from the smart folks I know from college who have gone into fulfilling careers as cryptocurrency VCs and founders has been fascinating overall. It's made me question how firmly I understand the value of "real things".

Note that I do kind of gloss over the "multiple slurp juices on one ape" stuff and questions about whether art has value. Much more interesting to me is the technical jargon that surrounds this communal hallucination that the bits on the blockchain represent amounts of money and that finance concepts can meaningfully be applied to them.

If everyone has mutually consented to moving around money this way in DeFi and it's working out ok (i.e. everyone is simultaneously giving each other a sly wink about the foundations but we're all having fun and it's fine), does the whole rest of modern finance also work the same way? What is the difference between cosplaying doing technical analysis on the blockchain and doing the other kind with stocks, options, futures, and commodities?
Yeah; ultimately no matter how many levels of acknowledgement, the other army's decision to attack is predicated on receiving an acknowledgement to the most recent message, not past ones (else you don't need an acknowledgement at all). There's an inductive principle at play; even at 100 levels deep it's the same problem as the original.
I find the same with Netflix. Some absolute gems have terrible scores because it is not the usual stuff people watch on tv

I'm impressed you got Oregon Trail working in Win95 with sound :)
It used to unpeg frequently (though not as bad as this TerraUSD episode). The stability has increased and the yield has decreased; a lot (yearly yield was close to 30% at some points). My guess is that they figured out how to peg efficiently as they have maintained the peg through various brutal crypto dips. The market does seem to think so (hence the low yield).
> That's a big part of the appeal of places like Hacker News and Tumblr- the focus on being a social network without adding in additional ad-delivery "features."

I myself wouldn't count Hacker News as a social network. There isn't anything that caters towards individuals making connections with one another. It's all about short-lasting exchanges between strangers on a given topic. The social aspect is fleeting and the network part is nonexistent (at least among users themselves. Networking has to happen through a third party). Not saying that this is a bad thing at all because HN is certainly a fun and appealing place to hang out online.

To the article itself, I think the author's graph is a little too simplistic. It only trends downwards. Some baseline features can cater to a more engaging discourse. The reason I say this is because I've been using an experimental social network called Minus (https://minus.social/#) which is very basic: you can't "friend" or "follow" anyone, there are no clubs or groups or private messages (though you can @mention), the main timeline combines everyone's activity, and you only have 100 posts available until you can't post anymore (but you have unlimited replies to other peoples' posts). While fun, it's hard to keep track of people unless you get into a conversation with them or unless they post frequently (though they can get buried by speedrunners who try to exhaust their post counts as fast as possible if you don't block them). So with Minus, I think there is still potential to add features that would positively contribute to the level of discourse before it would experience a downward trend
The emotions you’re expressing — awe and anger at disbelievers — are rooted more in religious sciencism than actual science.

I mean, it isn't?

Even the simple matter of port forwarding assumes you have access to the router you're using, and that's a major barrier for a lot of people.

I run the programming club at my high school (I'm a high schooler), and we use Github pages to host all of our stuff for this very reason.

I've used some old laptops to run servers within the network, but my school doesn't want us hosting anything public, and running everything through a free tunneling service like localtunnel is possible, but it scales so much better when students can just follow some friendly instructions to host a static site themselves.

It's not hard for the people with the privileges of (1) having a budget > $0 and (2) not having the adults tell you 'no' every time you want to try learn something.

Am I missing something? Even hosting static content on a server seems like a layer of complexity that is frequently unnecessary for basic use-cases.
if GP is referring to me, I wasn't making that point, I was mostly thinking about how ideation in the crypto space rapidly evolves because people are willing to try, all levels of the stack improve, consumers and investors rapidly become more discerning. lifecycles that are decades long in other markets play out in months or weeks in the crypto space.

It’s all too easy to confuse skepticism with science denialism. It’s important to be skeptical of scientific claims. This is essentially the core engine of scientific progress.
I don't think so. Single-master, multi-reader is the most common clustering pattern for all these databases. If you lose the app server that's handling writes in any of those systems, you have the same problem. Meanwhile, when your app server is down, the sqlite database is just fine, and so is Litestream.

I'm not thinking very careful in answering this, but I think there's a subtlety I'm not capturing well here, and that it's not the case that this pattern has poorer fail-over than clustered Postgres. I think there are more things that can go wrong with Postgres.
Ask HN: Confused – Whats the best extension after .com?
Hi all,

I am working on a peer to peer services marketplace (not IT specific).

If I cant get .com name what's the next best extension and why? I am sure many of you went through this. Hoping someone can share their experience / advice. Thanks!

These extensions are available:
.net
.io
.co
And the country specific extensions like .com.au .us etc
Sort of; 1 is just as good as 100, since whether the other army is going to attack or not is still dependent on their receiving your Nth acknowledgement, and past acknowledgements don't change the confidence of its arrival.

Which brings us to the relaxed case from the OP; make it so we only need one acknowledgement, and account for the confidence level of getting that one acknowledgement.
In NYC?
1) It's not clear it will be worse, many countries with single insurer/single payer have just as high quality care (Canada)

2) Leaving these people uninsured is not cheaper, you're paying for it already with significant healthcare costs. The same people complaining about the cost of healthcare turn around and deny preventative coverage to people who end up in the ER and you pay for it regardless.

3) It's the right thing to do, ethically, morally and financially (long term)

What an incredibly ignorant take, no wonder we don't have any healthcare solutions.
“This is probably good for society, as it puts more capital in the hands of people who will invest in things that succeed rather than things that fail.”

interesting how in your model wealth inequality doesn’t affect society at all. if one guy has a trillion and everyone else has a penny, it’s good for our society, bc he will invest in things that succeed, because no one else has a chance to succeed.
if "they" is referring to "me", I don't feel that the new one doesn't inherit or replicate other incumbent system problems. I like that its easy to try out, compared to attempting to try in the incumbent systems. for better, or for worse. its up to the all users to be just as discerning and pragmatic about participating or not. its great that many users are pragmatic supporters that accept things can go wrong and that they become a case study. less discerning users should also be like that, or not participate at all.
A couple months ago I was trying to figure out how they did “stablecoins” across multiple IRL currencies, which of course can fluctuate wildly against each other IRL. Their Discord helpfully explained that it’s just incentivized validator-oracles, which IMO is like crack candy for any crypto-Soros[0] out there.

Not that I think this is what’s happened, it just stood out that the grand claims didn’t even have any fine print, you had to go actually ask the community, “hey um what about this apparent contradiction?”

To their credit the community was super nice and helpful.

My understanding is the sales pitch is that it's quicker to move in and out of a stable coin then it is convert to cash. Plus you can avoid having to keep your funds locked in at an exchange. There's been enough exchanges disappearing with people's money that I guess keeping your cash on a blockchain with a stable coin looked more secure to some traders.

Mind you, I LOVE the idea of trill being trans/non-binary. This makes a ton of sense.

What discovery failed at is exactly what is tearing the USA apart. I love they realized why it didnt work and are doing better.
> consumers need to consume less

A lower consumption simplifies down to the equivalent to: (aj) reducing GDP per capita, or (b) reducing the number of capita (people). Structurally and morally, both of those are very difficult to manage. Ironically the argument for less “consumption” is usually made by the well-off people in wealthy economies. Weirdly war and political strife that destroys economic systems may be good for the planet (and the USA in particular wins relatively against other economies which have GDP destruction).

I would state a solvable problem as: how do we increase consumption, while decreasing resource usage? That requires efficiency, technology, and reducing the environmental cost of our economic systems. To achieve those goals needs a systematic global system that encourages those effects, while avoiding the tragedy of the commons. Politically we don’t seem to be achieving that.

> One of the issues with poverty and obesity is that a lot of people seem to think and argue poor people can’t afford healthy food.

I've seen poverty measured by toilet paper. A person who is working but poor may have money but their funds are so limited they can't even buy a 4 pack of toilet paper, or to buy in bulk, or to buy more when it's on sale. They simply don't have the disposable income every since dime is needed and already spent by the time they get paid.

With food it's the same way since poverty means that you buy what you can right now. Having worked shift work for 12 and sometimes 18 hours I know you don't want to do anything but eat something, anything just so you can get it over with and go to bed at a decent hour. I've actually had run around my house after a long shift because the end of my day was so limited. I ran around getting pizza pockets ready and getting my clothes ready for the next day. I was trying to get it done and not be up too late. I'd run to bed to jump in and go to sleep because I had no time to waste. It sounds silly but my time was limited and I wasn't really what I'd call poor I made just above minimum wage at the time but worked long hours to get overtime.

Also poverty means most times the person doesn't have cookware to cook food. Frying pans, a pot or more than one pot. Even chef knives or any large knife to cut vegetables. Cutting boards to cut on. It's all a big cost to get such items assembled.
The only entitlement I see is from those who think they're entitled to grow crops in a desert during a drought. Nobody is going to die if almonds aren't grown in the desert.
Problem/Solution stories: must see from YC
I’m not really interested in fault when this is a solvable problem with current tech. Consider that New Mexico gets enough solar power per year to power all of the globe. And it gets a ton of wind (70 mph gusts the last several days for much of the day!). And that’s just one state in the southwest and the rest get similar (or more) amounts of sunny days, wind, etc.

Though water rights are probably the lower hanging fruit to tackle…except it’s chock full of political issues dating back to the Spanish territorial days.

Politicians way worse than today in many ways found ways to build out the big infrastructure projects that made the modern southwest a possibility - ie the Hoover Dam, the national highways, and power grid.
What is interesting is that a lot of hard problems can be solved by making the network more reliable.

For example here is the writeup by Eric Brewer (of CAP fame) how Google is able to achieve CA (consistency and availability) in practice because of their reliable network architecture.

https://cloud.google.com/blog/products/databases/inside-clou...

Along the same lines, notice that while the first message can be arbitrarily long (for example the time and date of the attack, maybe the strategy), the ACK is only a single bit.

So in practice, Alice's message could be, "Attack on May 9th at Dawn, and as soon as you receive the message, set the hill behind you on fire."

So no matter how good the enemy is at capturing messengers, if at least one messenger gets through, and Alice is able to notice whether the hill behind Bob is on fire, they will be able to coordinate successfully.
Most Americans have never experienced a system like that, and will fight tooth and nail against things they don't understand or have experienced. They are told by billionaires who run the media empires that universal healthcare is expensive, will ruin the country, will remove their ability to get appointments scheduled.

Of course coming from any other country, this is ridiculous. But it goes to show you how out of touch many Americans are with how the rest of the world works.

>I'm reading your comment as admitting that the idea that any of these should be seen as mainstream investment vehicles is nonsense

Perhaps? Depending on your view on how much stupidity is allowed, the only thing that qualifies as a "mainstream investment vehicle" is broad market ETFs.

>There are many, many parties pitching people on the idea of investing in this stuff right now without pitching them on reading a bunch of code.

Yeah, that's what "caveat emptor" means.

>"This is all bullshit based purely on hype but I'm not gonna come out and say that, you just have to realize it by reading the code," basically.

you realize that both can be true? If some hustler pitches you some penny stocks and gives you false information (eg. fake earnings reports), that's fraud and definitely not okay. However, if you got suckered into some penny stock because some guy on wsb posted his gains and you got greedy, that's on you.
Describing someone else's success as messed up while riding the line between venting and emotional dumping. Blogging was seen as a weird nerd thing until the 2000s and got the usual response. I doubt Jason Kottke was spared the same experience. I sure wasn't! But I went a healthier path and took the chain of failures and small wins as learning experiences that have served me well in the years since.

Some people get bitter about failure, and then dump it in places where no one asked without any of the grace and introspection that might turn it from obnoxious to something others can learn from. That's the problem.
The zero-knowledge, copy/paste frontend development you’re describing is a big part of why so much of the web is such a bloated mess. It’s certainly not React or other FE frameworks that are the problem. At least not in and of themselves.

The pound peg broke because the price it was pegged at was fundamentally mispriced. The mispricing was the problem, not the pegging.

The reply is not addressing GP's concern. A survey of the literature of GNN fundamentals will contain a lot of repetition for someone who is already comfortable with message passing and neural networks (particularly neural ODEs) generally.
More so than not detecting threefold repetition, it is actually not good at endgames in general, very frequently struggling to find checkmates more than just a few plies deep. I’ve heard anecdotes from friends that played it, where they were able to converge from a losing position during the late middlegame or the endgame.

I spent from 2005 to 2020 doing almost nothing but vulnerability research, where the modal client project was a SAAS-type app, and my experience is that only a tiny fraction of companies building on Postgres actually use Postgres authorization features. It's far more typical to build this logic into the application than to build off the database's authorization features.

Nevertheless, if you're building an app that takes advantage of database auth features, that's a powerful reason to keep on using Postgres. You actually have one of the major problems Postgres solves for!

Best guess it doesn't really need a real executable peg since it provides such a convenient tax shelter to avoid realizing crypto gains. It's useful enough people are willing to ignore the issues and since it's backing isn't immediately examinable it gets to stay alive. On chain algorithmic pegs are vulnerable because their backing is immediately visible where Tether was able to just fake backing long enough to get deeply integrated into the crypto markets.

You could stake UST stablecoins for 20% APY. You could also get loans with UST collateral, and stablecoins are native to crypto. How do you move a dollar out of coinbase, into a wallet, bridge to another blockchain, and then stake it? That's only possible with stablecoins.

Well, hey, at least it looks like it's going down now.
Unless I'm misunderstanding something, I do think using SQLite makes a significant difference in the complexity of app deployment. When using multi-region Postgres, it's true that you only want the Postgres leader to be accessed by app instances in the same region, so the app instances all have to know which region is running the leader. But multiple app instances in that region can connect to that Postgres leader, so it's easy to do a typical rolling deploy. With SQLite, only one app instance at a time can write to the database, so IIUC, there will have to be a reliable way of doing failover with every app deploy. I suppose the same thing has to happen in the Postgres scenario when updating Postgres itself, but that's way less frequent than deploying new versions of the app.
Awesome! Happy to hear this :)
