Yeah I finally abandoned Windows for good after Windows 7. Up until then it still basically was familiar (except for the earlier change in Office to the Ribbon interface, which I still find unfathomable). Windows 10 was just a bridge too far. It was not worth the effort for something I wasn't using much anyway.
I'm not familiar with the design, but where are you getting the "millions of km" from? I didn't see that in the article, and my quick skim of the paper[1] suggested that that Ls (the length of the coil) would need to 200 km (given shortly after equation 15).

> What did you have to unlearn and relearn?

Twenty years ago I worked for 6 months in India as a consultant intern to Indian programmers. My experience is that Indian programmers are very gifted and clever but caught in everyday hustle. They tend to work chaotically, misunderstand requirements and lack long-term and fundamental thinking. I understand that because as I experienced it myself they had to fight with everyday annoying nuisances like power going off unpredictably. I had the luxury of a laptop (then a high-end 486 Compaq one) so I could shutdown at leisure but I vividly remember the many times light going off suddenly the nights and everybody moaning.

We were programming in server-side JavaScript, many years before Node was a thing.

I imagine GP meant unlearning short-term thinking.
Those all sound like local database features that one could add to an Ethereum client if they found them useful enough to bother, they aren't protocol-level concerns or "flaws in the design of eth" as you put it earlier.

> The data might be there, but it's practically useless.

The availability of the packed data is useful, just not to the end user of the node. Having this data widely available on the network means that anyone can spin up an archive node by peering with other full nodes, they don't need to discover and peer with the very limited number of other archive nodes, and the network doesn't need to worry about losing that data permanently if all archive nodes go offline.

> A user who discovers they need some archival data is never going to consider waiting weeks for the nearly 7 years of history to be replayed before running their query. Instead they will head over to etherscan and trust whatever it says.

Call me unprincipled but I don't think it's an issue that if a user needs data above and beyond what's needed to fully verify the chain and read and write to it, they're expected to either spin up a more resource-intensive node or retrieve the data from a specialized history service. Statelessness is on the roadmap, so in the long-term the historical data that Etherscan and similar services serve up to you will come with a validity proof anyways.
I don't get this summary how are you capturing a larger part of conversations
Most people (myself included) very much dislike dealing with coins. Having to find the 37 cents (or more likely having to break a bill) is a (minor) pain point for a lot of people.
Back in the days of paying cash for everything, it was both rare and amazing when a transaction came out even in terms of standard dollar bills. If you pumped $20.37, you'd have to pay the clerk $21 or $25 and get $0.63 or $4.63 in change back. Coins were annoying to deal with.

At the gas pump, you could control how much you spent precisely. So many folks would slow down their pumps as they approached $10 or $20 or whatever amount they needed and then stop on the even number.

In the commercial, pay-at-the-pump is a new and novel feature, so Jerry can fill his tank up to the top without worrying about dealing with the nickels and dimes.
> The study results suggest repeating the experiment with a larger sample pool and introducing randomized controlled trials covering more clinical parameters.

You're writing like you disagree, but in the sentence after that the actual "claim" says to do exactly what you suggest(get more data).
Doesn't this go both ways?

Employees would have perfect visibility into their peer's (and boss's) salaries and it would be impossible for employers to covertly take advantage of people with less leverage and poor negotiation skills?

Why would the global financial system move to a blockchain?
That's some great information, thank you. I always assumed wire nails were better because they are more pointy and more modern.
looks perfect, couldn't get payment to work on my international card though. Thanks for the recommendation!
They turned KITT into a blurry 3d blob, poorly lit to hide the flaws. Barely qualifying as a full 3d model. "Black car" is the appropriate name for the result, nothing more.

They disabled comments on the article, and on the youtube video. Combined with YouTube's newly hidden dislike ratings, we can't know how many viewers are unimpressed. Hype has more breathing room than ever before.
>Nobody has demonstrated better results than our public system without either filtering students or by spending a lot more money.

Could you produce a citation please? I've been under the impression that several countries are beating US in public education ROI, but since I don't have that source off hand and you've already made the assertion I'll go ahead and let you fill the burden of proof here.

Are you basically saying no (similar cost) private school beats the public system because by definition they can pick which student they have so they can't possibly beat a public system without filtering? There has to be some (similar cost) private school out there that could beat the average public school even unfiltered; these seems like a pretty tall claim to make.
This is a good breakdown.

Too much web3 thinkpiecing (both pro and anti) comes from people who've never looked under the hood. It's refreshing to see someone try actually try crypto as a developer, not just as a user, and go deep enough to figure out how things work in practice.

Moxie's critiques are valid. All of these are well known problems to the researchers at the core of web3 and all are the subject of active R&D.

- Point 1: people fundamentally don't want to run their own servers.

Clearly true. Vitalik gave a vivid example of this in a recent interview on Bankless pod. He visited Argentina, where hyperinflation has forced many people to use crypto or physical USD. He observed people using stablecoins, but not primarily via Eth L1 or any L2. Instead many transacted via Binance. Not BSC--Binance the centralized exchange! Which provides a Paypal-like UX.

Crypto researchers are fully aware. The plan is a couple thousand validators and millions, eventually billions of end users. Of course the end users will not run command-line geth, or run their own server in any capacity.

The plan is for them to use some combination of light clients or trust-minimized hosted services. This requires bringing transaction fees way down, the core goal of L2 rollups + sharing.

Also, today's popular clients are not particularly trust-minimized, which brings us to his second point. Paraphrasing:

- Point 2: current "web3" is really mostly web2. Under the hood, Metamask, OpenSea, etc just use trusted servers.

The fix here is trust-minimized services (= like Infura, but with every response bearing a proof of correctness) or light clients (= very similar, but using full nodes as interchangeable servers).

This exists today as a proof-of-concept. It is about to become feasible in production. The reason current Infura does not provide proofs is because Merkle proofs are 10x+ the size of the data returned for a typical query. Verkle trees fix this.

If you're curious:

- https://vitalik.ca/general/2021/06/18/verkle.html

- https://dankradfeist.de/ethereum/2021/02/14/why-stateless.ht...

Zooming out. Here is the Ethereum roadmap for the next two years, summarized:

- The Merge. This removes proof-of-work. The Eth ecosystem will use >99% less energy after this point.

- The Surge. This is about data sharding. Today a transaction might cost ~$50 on a bad day on Eth L1 and ~$0.50 on a Layer 2 rollup like ZKSync. After the Surge, L2 transactions will be nearly free.

- The Verge. This is about Verkle proofs and statelessness. These allow the core user interfaces -- wallets and light clients -- to efficiently follow the blockchain without trusting central intermediaries. They enable efficient proofs of any portion of the chain or its state.

I think these are fundamentally powerful primitives, the implications of which we've just barely begun to explore. I actually welcome the next bear market, since it shakes out the grifters. It is day 1.
> In reality, you would think about and act upon each in turn

Here's a real example from real coding I was doing, then:

color.r = 42;
color.g = 42;
color.b = 42;

I want to bump the 'r' and 'b' from 42 up to 255 but leave 'g' alone. So I,

1. Alt-click after the two 42's I want to change
2. Ctrl-Backspace, type '255'
3. Done

With a vim I could

1. Use '/42<RET>' or '?42<RET>' to search towards a 42 I want to change
2. Use 'n' or 'N' command to skip the 42 I don't want to change (possibly)
3. Use 'cw' followed by '255<ESC>' to change the first 42
4. Use 'n' or 'N' to get to the next 42, skipping the 42 I don't want to change
5. Use '.' to repeat the 'cw255<ESC>'

Alternatively with vim

1. Use ':%s/= 42/= 255/gc' to query replace the right occurrences
2. Answer 'y' or 'n' for each occurrence
3. Still requires more keystrokes, time, and thought than VSCodium

It's funny all these posts presuming that multi-cursor is a gimmick only used by idiots who don't know how to use regular expression query replace and the vim '.' command. Yeah, I know how to use those, and multi-cursor is often faster. And VSCodium has a powerful multi-file query-replace that is faster to learn than the equivalent vim/emacs/grep/sed.
I've never had apt-get update && apt-get dist-upgrade create any "highly technical problems"

Jumping major release version, yes there are always new things to learn. Windows is no different in that regard.

I agree that the Windows kernel is pretty stable. The driver and application landscape is another story altogether.
My company is selling such sensors. Europe only.

IoT sensors can do a lot of useful things for trains. Such as checking if a long train in Siberia lost a few wagons. Check if a door will break in a month or two.
I had an intensive daily meditation practice at the time which made it easier to do while in the sleep posture. It's definitely not a panacea since everyone has different needs.

Overtime I learned a lot of different techniques to help to bring my mind back into the body. I became obsessed because of how I had been avoiding my feelings for my whole life.

For me, I got extremely curious about what I was feeling either good or bad. That overall curiosity and desperation in a way forced me to pry open the dirty and grittier parts of my feelings and let them go.

I hope CBT or other techniques continue to help you. Definitely curious to know what other techniques may work for you.
Do you know of any financial structures or corporate structures that are not pyramid shaped?
To reverse this. Too many companies depend on open-source ecosystems to siphon a profit from the average dev by persuading them to work for free. Foss isn't free. It merely shifts the costs from users and corporations to that one guy in Nebraska.

Foss came about because RMS wanted to fix his printer, other academics wanted to share their code, devs didn't want to have to go through finance to buy software, and internet companies wanted to reduce their costs. The rest is just post hoc rationalization.
It used to be like you could google someone’s name and you could get their tax returns. But now you need to login to tax portal and the person will be notified that you looked up their tax returns.
Agree that developers should have to pay the cost for creating infrastructure to support the housing they build. But in general, infrastructure in dense areas will be cheaper per capita to build and maintain than infrastructure in sparse areas. So even if we make them pay the cost, the result will be massive densification, which I'd say would be a good thing, since it would make housing more affordable.
A unit test would likely have mocked the mongoid gem with the old behavior.

Integration test on the other hand…

Or Mocking one level further down, not sure about ruby but in Python there is a mongomock package which simulates most of the mongo queries in memory, so an ORM on top of raw queries does not need to be mocked. Because it simulates the database rather than just EXCPECT_CALL it’s also invariant to how you chain operations as long as end result is the same.
Some of the wording in the article is weird, and the "Context" gives very little of the relevant context.

> The current reference frequency for tuning musical instruments is 440 Hz

More accurately, the current most popular frequency for note A4 (the A above middle C) is 440 Hz. The article brings up the 432 Hz tuning but completely fails to mention that it isn't just an arbitrarily-selected frequency, but a frequency proposed by Verdi. He also proposed Scientific Pitch, which is tuning middle C to 256 Hz, making all C notes integer frequencies, and taking A4 to about 430.54 Hz.

I'm a fan of scientific pitch, and I tend to just use it as a default when I'm doing any audio programming because it makes it very easy to calculate all the pitches using C-4 as a base with frequency of 1 Hz.
The phrase "institution-grade" have the strongest meaning in commercial real estate, where they tend to be brand new buildings without any real risk of falling apart during your holding period. They are lower-risk assets. On the other hand, if you're talking about something bonds, you're more likely to hear about "investment-grade" bonds to describe the lower-risk investments. In other words, the exact opposite of Bitcoin, easily one the most volatile assets on the market. (If you want any more volatility, you need to start trading derivatives.)

A few billion in speculative investments doesn't make this "institutional" in a hundreds-of-trillion-dollar market, either.
Yeah that’s fair enough, and it’s changing so fast. I imagine alot of the current problems will be fixed over time… it’ll get there eventually. There are some good educational resources cropping up now e.g. Web3 University and rabbithole.gg
> Yes, if you need your computer to check email and visit websites, and maybe deal with digital photos and do a little light word processing, Linux is rock solid stable and more than up to the task

I would go further and say that browsing, email, and light word processing doesn't require a laptop/desktop at all, whatever the OS - this is what a tablet (perhaps with some kind of keyboard) would be perfect for.
Those packages generally don't "need" updating. I generally go months between updates on Linux systems with 100% uptime the entire time.
> Even nerds do not want to run their own servers at this point. Even organizations building software full time do not want to run their own servers at this point. If there’s one thing I hope we’ve learned about the world, it’s that people do not want to run their own servers.

Why is this true? At this point it's never been easier to make your own static website, deploy nginx, and get online. Maybe not everyone wants to make a website, but you would think that everyone that does want to make a website would be able to and deploying a server would not be the bottleneck.
I'm confident that https://www.levels.fyi/ would be updated over night with that info if it became available stateside.
Yeah, much of human intelligence is also just statistics. We do a lot of unsupervised learning and reasoning based on correlation.

The opposite of this would be causal reasoning but that is hard for humans as well. Not everyone can use causal reasoning, it requires many years of training. The discovery of causal mechanisms (science) is slow and it takes many people to do it.

For example the president of Turkey believes interest rates should be lowered in a hyperinflation. What can we do? Causal reasoning is hard.

I think we do something else, slightly different than causal reasoning. We're generating hypothesis and testing them out, in an iterative process. Like a GAN (generator+discriminator) or Actor Critic (policy + value function). More famously, AlphaGo was generating many rollouts for each move, one model to generate moves, another to evaluate their consequences.
They don’t own anything in a meaningful sense except the url, and even that is controlled by someone else.
I have a similar experience. A friend of mine was staying on SE Asia for an extended period of time and asked me to configure her router with an always-on VPN connection to the US to access her media subscription services. She had already signed up with a VPN provider. None of the standard VPN connection types worked (OpenVPN, L2TP etc) with Netflix, only the custom application that they provided. When I analyzed it, I found out that it routed traffic through other users' residential connections.
Their site broke recently. Before it had nice benchmarks included. Apparently string backend researchers are not that good in maintaining website frontends.
Awesome vid, the visuals of driving in the nail to softwood are especially helpful. Had no idea cut nails were tested to grip about 1.5x better than wire nails, I thought they were mainly just about aesthetics
You got me for a second there.
> From a user perspective, blockchains are less secure as there is no authority you can approach for chargebacks

This actually proves the point that security is relative. There are instances when I would feel more secure when an outside party can refund my money, say when the seller never ships the product I ordered. There are also times when I would feel less secure with chargebacks, like when I sell something on eBay and the buyer files a complaint with PayPal after taking delivery of exactly what they ordered.

Security wasn't an original goal of bitcoin. Privacy, anonymity, and immutability were, though the first to were lost a decade ago and immutibly is pretty well solved but also the primary cause for so much wasted resource consumption.
This tool is not at all scientific or accurate. One problem is that this tool assumes most of the water flows through rivers and out to oceans, when in many cases water flows underground in aquifers, emerging elsewhere. In the US south east these aquifers travel a long distance feeding many springs, which then lead to one of two rivers: the Suwannee River and the Saint Johns river.

Sounds like quality of public transport problem. Also, high schoolers are fully competent not to miss busses.
Both the viewer request and origin request hook both happen early enough that you can update the path

See https://docs.aws.amazon.com/AmazonCloudFront/latest/Develope...

I have used lamdba@edge and our primary use case was to rewrite url (to add languages information for example) so I'm sure it works in viewer request events.
His example of his NFT that gets shut down is showing that because of this layer of centralization, anything that can happen to normal assets can happen to blockchain. Governments can force OpenSea to take your NFTs, OpenSea can delete your ownership at their discretion, etc. All he is left with is a meaningless string of data on chain, while the NFT visual is gone. It’s not immune and protected like people think
Don't get me wrong its good that the option is there, but short of coding and operating your own full node Metamask will still be trusting a centralized third party
Could you elaborate on "mobile crypto please"?
I almost cry when I think about how Jaime Escalante lost his department chair (allegedly due to jealously) after being one of the most successful public school math teachers in US history. It's sad how incentives are set up for public school teachers.
No, the centralised url selling service decides who owns which monkey url and they have already used that power.

https://blockzeit.com/opensea-nft-marketplace-stops-hacker-f...

There is another example in the article - his nft was deleted from the marketplace, and nobody buying monkeys cares what is on the blockchain.
> Maybe because its familiar but different at the same time.

I would bet on this. That's why a lot of people like the concerts versions, instead of just listening to the studio version. It's the same... but feels new again, thanks to those small variations and imperfections from a live performance.

Still, I find it interesting they did the research for this, I love myth-busting, to know if urban legends are true or false with the foundations of data.

I wonder if for people with Absolute pitch this tuning could mess with them.
While there is precedent[0] for reclassifying a game based on content included on the distribution medium but not normally accessible within the game as released, I think you would have a hard time making that case here since you're probably going to have a much harder time inducing a GBC game to render an HTML document or JPEG image.

Think about it this way: there are two doors as the starting condition, only one has the prize behind it. 50% odds.
The host opens the wrong door, so only one remains. The prize MUST be behind the only remaining door.

The host gives you the option to select that door or he can start a new game where there is only one door and one prize.

Would anyone really argue that there is a difference in outcome here? But the logic I see is that people are saying you should switch because the probability in the first set is 50% even though its literally impossible in this scenario for it to be 50%.

I know mathematically it's wrong. But I hate this problem so much. I am convinced is a philosophical / semantical issue.
This is quite rare and also types would have done nothing in this case.
That's hardly linux's "whole spiel" and like any OS, you need to check that your hardware is compatible.

I grew up skiing Sunshine Village along the Alberta/British Columbia border. There's a lift called the "Great Divide" where the rider apparently starts in Alberta, crosses into BC, and then returns back to Alberta before reaching the top.

As you ride up, you're greeted by a sign that reads "Welcome to beautiful British Columbia", and then "Welcome back to sunny Alberta". My Dad used to always joke about the snow melt either traveling to the Hudson Bay, or the Pacific Ocean depending on where you are along the lift line.

Had to test it out for myself. Unfortunately the lift doesn't quite carve across the watershed boundary as I hoped, but it's very close, and it was fun to wonder about as a kid.
So, fun history, the 440hz standard was only settled in the 1900s. A competing standard was 435hz for middle C if memory serves.

I have a soprano sax which was tuned for the pitch system that didn't win out. It was called "low tone" if memory serves.

It's a fun antique which you can play out of tune to your hearts desire.
FWIW, threads lock after a few days. So if you figure this out within the next day or two you should be able to update the thread. I'm interested :3
They made a new function for the ‘old’ behavior… that makes it even worse. Just make a new one for the new behavior and everyone is happy.
I don’t want how much money I make known by anyone I don’t want to know. How quickly people who advocate for privacy and data ownership acquiesce when it comes to salary data. The transparent-salary movement is a terrible crime against privacy.
"Was associated with a slight decrease of mean" is a claim. The p=0.05 convention requires that you report that the mean was not found to be different from the comparison distribution.
