> How does a cryptocurrency actually solve the lack of trust?

I said it was an attempt, I'm not sure it solves it..

> If you need to hide stuff from the government

All governments are not good. The US government for instance "froze" (basically took) all the money WikiLeaks had, and made it impossible to send them money through traditional banking systems. So crypto-currencies have already been important in funding an organization that uncovered war-crimes; which is a good thing.

Not all secrecy/privacy is criminal behavior, sometimes it is actual journalism. I guess we have seen so little journalism in the last few years we barely remember what it looks like.
If you'd walk into a lead dev position after only fiddling with JS for 2 weeks by watching YouTube videos, you'd be kicked out faster than any sales person ever would. The reason you felt no threat was because you knew what you were doing,or at least knew good part of it. Sales people have one purpose in companies: to sell. There's nothing else. So if,after 2,3,6 months they can't do it, then of course nobody will keep them. Only shit companies hire/fire sales people like there's unlimited supply of them waiting to join,but even the good ones won't keep them forever if they can't do the job.
> Up until the invention of Bitcoin, there was ZERO scalable way for me @joeblau to send you @louwrentius money the way I send an email. By that, I mean the only thing I need to rely on is a protocol (like SMTP) and you'll receive it.

Maybe because it's not a need most people have?

> The problem is that money (paper money/currency) is not the only thing that has value which human beings transfer among each other. We share music, art, poetry, equity in companies, ideas, code, etc. What Ethereum does is take the idea of "Digital trustless money transfer" and expands it to "Digital trustless value transfer"

This still means nothing to me. I can't relate to this.

> Let's say I own TSLA stock and I want to sell it to you. I can't, without going through a middle-person. (they take cuts and fees..)

So it's about not wanting to pay transaction fees for buying stock. Hmm, doesn't really sell it to me, quite frankly.

No mention of how to get out of this unhealthy habit.

I'm struggling with this myself. Some of my conclusions so far:

* When I am sleep-deprived I am less productive. So I spend more time doing "work". Then I have less time for everything else I want to do (family, cooking, sport). So I take more time away from sleep. And the cycle repeats. Sleep deprivation is self-perpetuating.

* What I do at night, when I am exhausted, in 2 hours can be done in the morning in half an hour.

* I get angrier and negative much more easily when I am sleep deprived.

For my particular case: limit the time dedicated to "work" and do the other things in the time it is usually dedicated to it. Stay away from screens past 11. Listen to ebooks for falling asleep. Use the good sleep energy to finish work stuff earlier, do more exercise, etc. Break out of the vicious cycle and start a virtuous one.

I still fail at doing it from time to time. I think this must feel similar to what relapsing alcoholics feel. I try to not be too hard on myself and keep trying.
I bet this is pretty common among parents during the pandemic. Between homeschooling/work, the only time a lot of have is late at night.
The anecdote I heard was that it was because there was no good way of getting data on the USSR over-the-horizon radars - other than the times where their signals would reflect off the Moon and could be analyzed by the US, given good enough antennas.

The one thing that still puzzles me is, how that unified memory thing works and actually handles contention between GPU and CPU without slowing either down. There's not much information out there how it actually works.

Anybody has any details?
The programmable part is most interesting and unknown. Payments can be made to go to one party or have built in alternatives if they die prior to transfer. Payments can also require specific documentation or have a time limit for transfer. How exactly this might most commonly be used is all conjecture, but there are many possibilities and few built in limits.

Oddly enough making payments programmable also introduced some of the first bugs in payment programming which raises many issues with the whole concept. In any case, it is all moving forward very fast.
Tell me how someone living in Rural Africa can get any useful access to the Ethereum blockchain, without accepting a significant loss of expected benefits.

Frankly, if we're going to be broadly racist and otherwise discriminatory about this, I would say that Ethereum and other blockchain systems are vanity projects for first world, white, city dwellers, with very little relevance for the rest of the world.
This is common knowledge in embedded circles, where weak memory models are the norm.

This article doesn't address a different kind of memory weakness in some ARM implementations (and I presume other architectures) that you can run into when sharing memory between processes.

The data cache is virtually tagged, virtually indexed, which means that the cache is keyed with the domain (essentially the process number) + the virtual address. This means that the MMU doesn't have to be consulted for cache lookups, however, if you have two different processes mapped into the same physical memory, the writing process must execute a flush instruction, and the reading process must execute an invalidate instruction.
Wordpress is a brilliant example of Inner Platform Effect[1] in all its hideous misbegotten architecture-iness, and symbolic of (and literally) everything wrong with the web we now have today.

A newer example of that same effect is Dropbox, which allows users to read and write files to web-based storage and share with others. Great for Dropbox Inc; piss all use to an open web.

First Rule of Open Web: Shoot all the Middlemen. Because they are the first indicator that you’ve done it wrong.

And if you still can’t see the red flag these “middlewares” represent then shoot yourself too, because you’re part of very the same problem. Nerds love complexity, and they love devising complex solutions to problems they’ve created themselves.

That you so completely missed the point without even trying sadly demonstrates that we have a very very long way to go.

You just keep acting like the “caveman lawyer” from Saturday Night Live and refusing to learn or acknowledge anything. You are being obnoxious and just continuing the HN trope of “blockchain is totally worthless despite it being worth hundreds of billions - the whole world is wrong not me!”
DNS and its per-TLD registration procedures/rules and mandatory protocols for transferring your domain to another registrar (depending on the respective TLD) are about as open as it gets. Which is probably why Google et al want to kill it via DNS-over-HTTP and complex amendments to the DNS protocols themselves.
> ”Does this sentence actually mean anything?”

In more traditional software engineering language, it means “you can run stored procedures on an incredibly slow and limited distributed database.”

Also those stored procedures are immutable, written in a language with more holes than Swiss cheese, and you have to use a scammy cryptocurrency to pay for the privilege of running these unsafe programs. The adherents call this “web 3.0” in some kind of ironic joke because it’s nothing like the web.
I too don't need any of the features that cryptocurrency brings. However, cryptocurrencies are making substantial headway on solving the hardest class of problems that humans face: coordination problems. Common examples include the Tragedy of the Commons and collusion [1].

Vitalik has written some surprisingly approachable pieces on the various problems that cryptocurrencies face. It's not too much of a leap to see how these problems appear in non-cryptocurrency contexts. The value I see in cryptocurrencies is that they must develop robust/antifragile solutions to the coordination problems that have plagued society forever. Even if some problems can't be solved, then there are mental tools for making sense of what's going on.

I don't think it is this. It is about monopolies. The FTC and SEC have failed us. Monopolies tend to have some positive aspects because of economies of scale but it destroys innovation and competition. Just because an unusable piece of tech exists, doesn't make it open web. Just look at the rise of Slack: IRC has been around forever but never used en masse. There should be forced interoperability given the amount of government money spent on research that created the internet and its tools.
That's a nice argument against cryptocurrencies.

They enable darkweb sites like Silk Road and it's successors.

I follow a similar pattern, but a major component for me is anhedonia / depression. I don't have anything in my life that is fulfilling or exciting or fun.

The problem with arguing by analogy is that there are two possible cases:

1. Your analogy maps precisely, in which case it's no simpler than arguing about the original thing.

2. Your analogy is imperfect, in which case your conclusions are suspect.

Case #2 is most common, and the argument usually continues by proposing a different analogy. Now you're arguing about the merits of your analogies, rather than about the topic itself.

Analogy can be a good pedagogical tool, highlighting some aspects of the problem, and giving you an intuitive way to connect to them. But eventually the analogy always breaks, and now you've got to un-learn the analogy before re-learning the reality.

Formal systems aren't arguments, they're assumptions. As long as the assumptions hold, the formal systems are useful. If there's anything to argue about, that's a limitation of their utility.
I think you’re misconstruing his points by bundling it with the overused interrogative of “are you saying...”, he is saying it has value if the people so decide. A government regulation forcing people to do something they already aren’t doing leads to the sort of didactic nonsense like running government sponsored commercials every 20 minutes telling you to wash your hands and use hot water to combat covid.
Masters of a craft may be very good at a number of different crafts. The only difference between "master of" and "good at" is often how you feel doing that activity. Pick the one that you enjoy most and mastery will come.
It is kind of disappointing that the discussion got side tracked to the computer budget in the classroom, which is totally missing the point.

Perhaps it is a good idea to watch carefully the opening statement of Professor Papert:

The mess we are in right now (such as https://www.c-span.org/video/?462071-1/technology-companies-...)
might have been avoided if we had a few generations of kids grown up in the Professor Papert's vision of "Educational Jet" instead of "Educational Stage Coach with Jet Engine" (zoom?).

To trust a currency, you must trust the institutions that manage that currency. You have no control over it.

To trust a cryptocurrency, you must trust the algorithm that runs it. It's fully auditable and predictable.

It still takes me several business days to complete an ACH transaction in the US, and requires I trust the banking system. Transferring cryptocurrencies happen much faster and don't require the same kind of trust or centralized management.

What you see as anti-features are good reasons why they won't replace the dollar yet, but they still have a place in the market.
In my opinion, moving a large amount of money using crypto currencies, legally and without risks, it not easy for most people. I would say it's a lot harder than going to the bank and letting them manage the transactions database.

Multiple aspects. PoS offers much, much stronger security than PoW while being about 4000x cheaper to run and sustainably decentralized. Sharding (along with rollups) allows for a truly global scale platform - over 100k TPS, potentially 1M, while still running on normal computers in people's homes. PoS is a requirement for sharding, as dividing security under PoW would make each shard too easy to attack.

Last but not least, full eth2 turns eth into a positive yield asset, a share in ethereum (real income depends on fees paid by users - ethereum already dominates).

https://cryptofees.info/

To not overhype, the current launch is really an incentivized testnet only for PoS itself - real ethereum still runs on PoW as it was. It's important because it shows that after long delays eth2 is finally starting to happen, and because consensus itself is like a car that can drive without transporting anything or anyone - not very useful at the moment, but changes required to make it useful are relatively small compared to building the car from the ground up.
>aside from being a developer for Apple's platforms who occasionally looks around for CI services

So, you give him all this shit and you're not even using his service?

>There's still a huge hole for a service that lets you rent a Mac for the a couple minutes so you can build your Xcode project. It's not your fault that doesn't exist, it's Apple's.

If we're talking for CI of builds, sure. But in that case, one wouldn't be much affected (the C in CI means continuous, so you wont just rent for a few minutes).

Otherwise, as a user, I'm quite satisfied with less developers being able to build XCode projects and submit apps without even owning a Mac to test them on. Looks like it would bring a delluge of poorly ported apps based on cross-platform APIs and only tested in non-Mac platforms (if that).
Here’s how you fix this. Go to bed early and wake up earlier. I do honestly believe that young adults naturally stay up later though. I think there’s an evolutionary reason for it, basically to keep the nights watch and ward off predators.
You just need to add some compiler options; /MD should get the size down quite a bit already, then decrease the file alignment and merge sections together:

/MD /link /align:4096 /filealign:512 /merge:.rdata=.text /merge:.data=.text

That produced a 1.5K binary, which with a custom stub should reach 1K.

It's fine to criticize a technology and saying that you don't understand what problem it solves, but responding to every comment, even those that make clearly valid points, with "means nothing to me" and "not a problem for me" without any counterarguments is quite rude. These people are taking the time to answer your questions.

For example, intermediaries such as brokerages and banks taking money from your investments and selling your data (and order flow in the case of trading) is clearly inefficient and unnecessary, even if you don't care about it personally.

On PoW, it's currently 2 ETH per block, with a little bit extra for occasional "uncle blocks." This is fixed but has been reduced a couple times by hard forks.

For PoS, issuance is a formula depending on the amount staked. How that works out: https://docs.ethhub.io/ethereum-roadmap/ethereum-2.0/eth-2.0...

If you want to dig into the actual formula, it's explained here: https://benjaminion.xyz/eth2-annotated-spec/phase0/beacon-ch...

Until PoW migrates to PoS, probably in about a year, they'll operate in parallel and we'll have both rewards added together.

A final factor is an upcoming change to the way transaction fees work, which will burn most of the fees instead of awarding them to validators. That will reduce net issuance further, possibly even taking it negative.
I know making tiny Windows executables like this is done just for fun, but I'm curious if there's technically a performance loss from merging sections. IIRC the sections are split up and 4k aligned because they have to be page aligned in memory anyway.

Okay, let's do some back of the napkin calculation.

The specific heat of Hydrogen gas is roughly 20 J/gC at high temperatures[1]. It would be much higher for a plasma but I couldn't easily find a number.

At 100M degrees C, a single gram of hydrogen would have over 2 Gigajoules of thermal energy. 2 grams of hydrogen would have the same energy as a literal ton of TNT.

It's not untenable, but its not really something that should be brushed off as "its only a couple grams of fuel" or "it can't have a runaway reaction".

I don't see ... AT&T losing anything

AT&T lost big. It ended up going bankrupt.

The "AT&T" you know today is not the same company. It is Southwestern Bell, which bought the AT&T brand in the bankruptcy fire sale and renamed itself.

It did so because AT&T was a more valuable brand than Southwestern Bell. Looks like it worked.
We used to have this. The retentions/QA team was under sales and would do a closed loop feedback system back. They were also paid commissions on 'saved' customers. Apart from retaining the revenue that would have gone otherwise, it was good way to fix some ongoing sales issues ( gaps in the pitch) and provide necessary feedback to the marketing on how to position the product.
And during this time slot for oneself, somethings can't be done as it was done earlier. Physical stores are closed, sometimes there isn't enough space to watch your TV in the desired volume, you can't go to your yard and do your wood-working hobby.

Well I have plenty of friends in Argentina, and Ethereum is helping them live through hyperinflation.

Their currency is plunging, their banking system is corrupt, so these are their options:

1. Trade Pesos for USD on black market exchanges. Hide cash in safes & under mattresses
2. Purchase Dai or other stablecoins. Keep money in multi-signature vaults, earning interest through lending protocols.

Plus, cryptocurrencies allow many of them to work for foreign companies and get paid directly in stablecoins.
The problem (partly) is that the F-35 program puts money into 307 congressional districts in 45 states [1]. These insanely expensive defense projects are wealth transfer programs that make contractors like Lockheed and their many sub-contractors rich, and also create jobs in these communities.

That a fighter plane may or may not come out the other end is only nominally important, the key is to spend the money. The more money spent, the more people get work. That keeps people elected.
