This is exactly the problem the Randi Challenge tries to solve. There are reports and papers from time to time about ESP, but as far as we know they are just flukes, p-hacking, bad experiment design or plain lying. Some of them get press coverage, but the press just copy&paste the press release.

So the idea is to make some challenge that where there is a magician team to detect frauds, a statistics team to avoid p-hacking and minimize the chance of flukes, something equivalent to pre-registering and other security measures to ensure the result is legit.

What is the best scientifically documented EPS experiment?
That's why it's so important that Tesla may make it possible to buy cars with Bitcoin.
"Bitcoin is almost as bs as fiat money" - Elon Musk, https://twitter.com/elonmusk/status/1340588909974200321

E.g. it's still not the ideal, final solution - but Tesla seemingly aligning to being on the side of the "army of HODLers" makes business sense; you don't want that army that's financially incentivized via the MLM/pyramid scheme that it is to start rallying against you and your products/services.

You admit that it's a strawman to say Bitcoin is meant to replace Visa.. but then why argue that?
I too hadn’t read any of her stuff but I had not heard of her until just a few years ago. After reading the parables and kindred I am a bit dumbfounded I hadn’t heard of her before. Her genre is the stuff I have thrived on since I was a teen. I’m honestly a little pissed (maybe partly at myself) since the reason probably has a lot to do with her skin color and gender. Anyway I’d highly recommend the parables as a starting point. They seem especially prescient today and were a great read.
Show HN: Easier way to study long articles – good for graduate students
In such a serious case, once the accused was identified by TrueAllele, shouldn't a further test be carried out by a human to verify the results.
I don't think Zuckerberg was ever the "I started company to solve interesting problem" or "I want make world better place" kind of person.

But is maybe the only inflation story anyone can come up with? Venezuela is misgoverned, but how do I know bitcoin governance is better? Bitcoin exchange rates are not stable. I can only hoard it, it's not an investment and not a currency.
The obvious connection that we’ll see in the news soon is how companies will combine this with all the digital tracking and profiling being done. Every message somebody sends to a teammate in an online game or discord conversation will be a factor in a job application result 5-10 years later
Why all the downvotes? lol. I started reading but noticed I won't have the time to finish this booklet of an article bjt was still interested in the gist of it ... don't get the HN community sometimes. Anyway thanks for the answers i got
Yeah, this has been one criticism of EU's Article 22...
It's interesting you don't consider Android one of Google's platforms.
If the reports of BTC going to 100K by EOY are true, they just turned $1.5B into ~$4.5B.
A directory per project is a good rule of thumb. I generally avoid directories for file "Types", thats what file extensions are for. Also:

- Adding a directory to an otherwise flat project at least 2x the complexity, so wait until there's a good reason

- Every directory should have a readme. If it doesn't have a readme doesn't deserve a directory.
Well they did until the British exiled them all to build a US naval base on Diego Garcia. And they would very much like to return home. The UK courts have ruled in favour of the Chagossians, but they are consistently ignored by the UK and US governments.

I actually don't find that convincing at all. He dismisses the idea of it being castoff as "special pleading", but what else could it be in the galactic rest frame? Same for the size and tumbling: the most reasonable artificial hypothesis was that it was a cast off chunk of solar sail, essentially litter, and that's still completely consistent with the evidence. His best argument was about the possibility of a natural, normal-shaped object just being a lot brighter on one side, but he barely mentioned that for some reason. I'm a lot more convinced that an artificial origin is reasonable to believe.
This position makes all sorts of unfounded assumptions about the nature of your government, that it is operating in your best interest, that it hasn't been captured by outside forces/interests etc etc.
As I said above, this is not someone hitting a rate limit.
Just imagine the sheer fucking arrogance of demanding people submit government ID for a social media account.

I hate that company with a passion. My mother is addicted to that garbage, and I don't know what to do about it.
That's like an accountant, accused of embezalling, refusing to hand over the ledgers because "there are just too many records to go through". Yeah-no, that's kind of the whole point. We want to find out what you've been hiding in that wall of paper.
Don't get me wrong, I see the appeal for Google of having it on there, but from the sidelines here, it seems to me to be terribly wasteful. It's like the energy consumption angle was never even considered. I presume it wasn't.

OT - where does your username come from? I'm sure it's not, but for a Brit to read it, it stirs thoughts of a terribly un-PC origin! :)
Will the Future Be Decentralized?
Are you sure you can't spend Bitcoin directly for goods and services? Have you tried? When was the last time you searched for physical shops near you [1] that accept it?

The end result of that tiny little error rate was tens of millions in settlements and legal costs, families permanently separated by government mandate, and multiple people spending more than a decade in prison.
Western Union has been doing this for > 150 years.
Gold is a decentralized store of value too, to be fair.
> quantum computers are more similar to analog computers

I can't speak for all architectures, but the ones I'm aware of absolutely are analog computers.
the key technical innovation that bitcoin gave us (that ethereum and other systems took to the next level) is a replicated state machine shared by untrusted peers. That's a huge deal for decentralized systems. It turns out that economics is a good way to keep network participants honest.
The other day I was thinking about Tesla employing guy from the Wall street and now all it looks as they capitalizing on Elon fame, people gullibility and and inflating economic balloon by mimes.

Basically idea is simple if you have a billion to spare, you buy something very cheap, then you say that that will be most important thing in the world. Many people buy it, and then you sell your share.
Don't get me wrong I love what Tesla and SpaceX do, but in this game I can envision that Elon wins, and many other ordinary people will lose.

In some way I consider all this - very, very wrong.
My wife, an employee of freetaxusa.com, said that you can write in to them with more details (I showed her your comment, and she wanted more details), and they will fix the problem. Usability is super important to them; I am the one that has to do taxes every year, and the company asks my wife to watch me do it to learn what trips people up.
Not sure about other places, but the UK and US treat this situation as equivalent to a sale of the cryptocurrency. Capital gains tax may become due.
But your example use case will be made illegal soon - that bitcoin ATM won't be allowed to give cash to an unbanked person without them providing their birth certificate, passport, 3 forms of utility bill and a driving license, then waiting 3 days for identity verification to complete.
Perhaps in a just society. Most places, the state and it's agents can do no wrong, there's almost no incentive to do the right thing.
About a year and half ago I was applying for a software engineering internship at Goldman Sachs and they made me take a Pymetrics test. One of the tasks was to press the spacebar as many times as possible in 30 seconds. I didn't do the task and withdrew my application.
Because tools like ripgrep are in your Linux distros package repos. You don't need to update them manually.
For me it solves "trust". See, Americans find it so difficult to relate to this issue because US central bank has such strong economics that a major event is unthinkable.

But going back to 2009 Greek crisis and the "bank run" prevention. Same thing happened in Argentina before and also in Mexico (the ones I know of).

We people in these countries dont trust our monetary and banking systems. The traditional way to offset that was gold or USD. But they are not so liquid or easy to store.

Cryptocurrencies are an instrument to detach the "value transfering" properties of money from the government control. With high liquidity and extremely easy to store.

The inefficiencies of BTC (performance, traceability, ease of use) are more technical details that people has been slowly tackling.
Ask HN: What financial services does your company need?
Aside from invoicing, budgeting, payroll, HR, etc, what are some solutions you feel like your company need?
It doesn't seem like science, or it's selectively chosen science.

If we must do these tests, I should be able to take one or a few of these and keep that as a record and not have to do them again. But instead, I have to repeat the process for every company that gives them (recently, Berkshire-Hathaway and it had to be done before anyone would even speak about the position). These things rarely test for job-specific skills and are supposedly generalized intelligence tests, so the skills should be widely applicable, and therefore I shouldn't have to repeat this often. Hell, I do less for a drivers license renewal and 2 tons of metal at 60 mph is more lethal than most jobs behind these tests. Typically they've been math, reading comprehension, word association, memory, personality, and abstract/spatial thinking, which, frankly, was already done through high school and college. If the goal was finding signals for successful applicants, they already have had these signals.

To me, that says they're less interested in finding out how smart you are, and it's really more of a filtering tool where science is being used to give it more credibility than it deserves.

And of course, referring to the article, because it's AI, there's a gray area of accountability that I don't think the legal process has caught up with yet.
> They do because they can, and because the damage still falls into the "acceptable losses" column.

Yeah, until they piss off someone too big to not give up without a legal/public fight or they piss enough people to make a dent on their bottom line.

I think Google right now is just coasting and the short term evolution is just reactive/siloed plans but no bigger picture of where they want to go (basically just "evolution for promotion points")
I was part of a very in-depth evaluations of both Pymetrics & HireVue for a large company recently (2 different evals, among others). Some interesting things we observed:

(1) It was not clear to us, with any level of certainty, whether either tool did anything more useful than filter out people who don't want to take the test / don't trust "AI".

(2) It was not clear to us, with any level of certainty, whether (1) was a useful, arbitrary, or counterproductive selection criterion for the roles we were hiring for.

(3) It was very clear to us, with a high degree of certainty, that both impressed a LOT of the higher ups

(4) It seemed somewhat clear that both were unlikely to get us sued (note: this is a high bar). However, HireVue (as of a year ago) could not in ANY meaningful way substantiate this claim "AI is more impartial than a human interviewer, as it has no bias," and it angers me that they make that claim.

After conducting a bunch of reviews like this (including other tools), I concluded that most AI recruiting software is a combo of (a) very useful process automation and (b) hocus-pocus, magicical, pseudo-AI. I had people telling me they used supervised learning because they had a team of supervisors in India. I had people telling me they had "Custom AI" when they were just calling some random unverified third party API. And I OFTEN heard nonsense, unverified claims of "unbiased" AI, as if eg training a hiring model using geographical factors won't tell you "don't hire non-college-age people from the south side of Chicago".

If anyone is looking to use recruiting AI, get a good IO psych person and listen to them.
Congratulations on the launch! Keeping track of our AWS costs and attributing those costs to each team was a huge pain at my previous job, a tool like this would have come in real handy then.
Yeah but Javascript can actually be used to create a blockchain or any number of applications. I bet SpaceX could land a Falcon-9 with Javascript if they wanted nightmare difficulty.

Bitcoin's main purpose for everyone I know is to buy drugs and treat as an 'investment'.
It's not just like voting machines if it's just software. Just give it the same DNA as input and check if your results match the others.
I wouldn't be surprised if "incorrectly averaging" and similar are very common software errors.

The reasons are manifold, including:

- Normalized values need to be averaged differently the absolute values.

- Floating point has limited precision, even just correctly summing/multiplying numbers need special care if you care about correctness. Results can, in the worst case, be of by a massive amount.

Often you don't need to care about it so it's not uncommon for especially junior programmers to be not so aware about it.

I mean in the last 3 years of working as a professional software engineer/developer I didn't need any of this at all, but once I do I know what to look out for.
That's my experience as well. My master's is in bioinformatics and I worked for several years in biotech.

I got frustrated because my concerns that my team's development practices were causing issues on a regular basis, were ignored. I was continuously able to predict what issues we would run into, but no-one seemed to care - I even had a manager tell me, that it was good that our software was buggy, since the client would continue paying us to fix it

I've since left the biotech industry. There's a limit to how many times I want to run my head against that particular wall
If you look at the history of the gold standard, this comment doesn't really make all that much sense.

The gold standard attracts a lot of people because of the naïve view that the government can't debase gold like it can fiat. However, that view is naïve: the gold standard doesn't prevent debasement, it just means that the government has to make a choice between maintaining the gold standard or pursuing the fiscal policy. (And the moment of decision can be delayed a surprisingly long amount of time.)

Yet, historically, when forced to make the choice, governments have almost always chosen continuation of fiscal policy over the gold standard. Many times (e.g., the early 1930s), governments chose the gold standard only for things to get even worse and instead opt for fiscal policy. In the long run, every country has ultimately abandoned the gold standard.
You could ask the same question of calculus (or any theoretical domain of knowledge). The rules of derivatives and integrals don't, in themselves, give a model of any particular empirical system. But they are a tool/language that can be used to describe/build/evaluate models for systems.

To give examples requires an agreement on exactly which domains of knowledge you consider to be part of "complex systems", so based on your question I'll assume that you consider chaos to be part of it.

For example, the Poincaré-Bendixson theorem saves researchers time because they don't have to consider the possibility of chaos in 2D continuous state space models.

For example, since we know that weather is a chaotic dynamical system, we can give up on the hope of ever being able to precisely predict the weather a year beforehand. This saves researchers from spending their time on impossible objectives.
MicroStrategy is a very expensive way to own Bitcoin
The VC-finance industrial complex is a problem, Bitcoin being the next MLM scheme they're trying to profit from by taking advantage of the broader undereducated society.
We have been cornered into nihilism. We've been shown that any attempts at making positive change in society will be crushed by entrenched power -- e.g. Bernie Sanders, climate movement, etc. So might as well just make a quick buck instead.
Calcite has planning rules to "push down" filters to the underlying adapter.

So I could push down filters to Git itself if that makes the scans any faster.
I made Dr Kleiner sing "I am the very model of a modern major general": https://www.youtube.com/watch?v=koU3L7WBz_s&ab_channel=Shawn...

It's pretty trash, but it's not completely horrible. It's also over a year old, so the SOTA is likely better today.
I'd bet Amazon has more retail customers trying to get disputes resolved, than Google has business customers attempting to do the same, yet Amazon manages to get a human on the other end of the line. And I'd bet that Amazon's disputes have far less monetary value per incident. Maybe apples to oranges, but it's impressive from a customer service perspective.
Large numbers of the 'get rich quick' crowd that you speak of become poor after each crash. More will follow.

Each time this happens, I stand in awe of the brilliance of bitcoin - not so much the details of UTXOs or hash magic, but the choice of time base and halving intervals.

Its as if it were designed to be a FOMO feedback loop from the outset.
The fact that its still working after so many boom/bust cycles is amazing.

[Edit] clarify reference to parent
If everyone switched to BTC employment in the financial sector would not shrink. Are you saying it would? I can put a bundle of dollars in the mail but even if that was free, it is still risky. My understanding is that I pay my bank to hold my money and transfer it because it is much less risky than doing it myself.
I don't think I've seen that! Thanks! Happy to accept a PR with a link to it.

The "template package manager" sounds very cool. Perhaps Stamp as a format for the CookieCutter Package manager would be a good combo. Not sure haven't taken a close look, just thinking out loud.
No, calling an "Assistant Professor" a Professor is like calling a "Major general" a "General". I have only ever heard full Professors referred to as Professors, and Assistant or Associate Professors are called by their full title, or simply "Dr.". It's possible some students might call them professors, but it's not the proper term.

In practice, these are tenure track positions, and not all teaching staff have them. For example, as a postdoc, I might teach a course at a college nearby. They might refer to me as "Adjunct professor", which is a temporary non-tenure-track position.
These two comments are giving me two more reasons to try radvac
Gold is unique, few metals can match it's shine and electrical conductivity. But there exist many cryptocurrencies which can act as "a system for transferring bits in a decentralized fashion over the internet". Many also do a far better job than bitcoin. So shouldn't they be more valuable than bitcoin? Etherium, Monero etc

Yes, but you really can't fight the government and run a parallel currency. If the government bans it then you cannot use it for any legal transactions.
I do believe that there are some solutions that we could (and will) come up with, but they do require radical shift of priorities in people's lives. Currently our society is just blinded by "chase money by all means" which was always a part of the humanity, but definitely got worse since Commercial Revolution, then even pushed further by Industrial Revolution. At the same time I feel like the pushback is finally slowly showing up in many parts of the society.

I wholeheartedly agree that we definitely do need some vehicle of value, and it might as well be currencies as we know them now, but with some hoarding-prevention mechanisms built in, or maybe some other way to figure out a value of time you provide to the society. Right now we rely on free market for that, but is the coffee you buy in the morning of same value to you as it is to the person in the queue after you? And if that coffee helps you build more value to society than your fellow man for whatever the reason, maybe part of that difference could also be captured by the coffee producer as well. If price of coffee was expressed in something like a fractional unit of your value in a day, let's say 0.02u, then you'd pay the same price, yet with wildly different absolute values. This is just random thought, and it probably will fail in hundreds of ways, but maybe something to spark your imagination.
The "economy" is some number larger than (2^999999999999999999999999999999999) of decisions done at every second. Unless you or some cabal of godly beings exist they cannot determine whats a "good" equilibrium in the first place.

Furthermore, to describe descriptions good/bad to a market is against the definition of a market. It is what it is. A high price signal lets others that they should come in and get involved and thus bring the price down one way or another.

Being humble is a good thing. I cannot understand how certain ideologies or peoples always proclaim to know whats best for a stranger.
This comment is unlikely to win me many friends here, but it is worth considering that while Bitcoin is, nominally at least, decentralized and free from government control, internet access is not.

A simple glance at the trend of governments to partially or to fully shut down internet services to certain areas in times of unrest or mass protest means, in the case of Bitcoin and other cryptocurrencies requiring collective transaction verification via online communications, that a loss of internet constitutes an inability to conduct financial transactions for those thus affected.

While I applaud the efforts of so many to free the world from government control of "money", the full implementation of this effort should be preceded by freeing internet communications from the control of those same governments, otherwise what appears to be a new financial "power" is actually a new financial "weakness".

Think over this carefully.
> While away on vacation, I once sent $1000 in cold hard cash, on a Sunday, to an unbanked person in Los Angeles, in less than 1 hour, thanks to bitcoin and the recipient withdrawing it for cash at a Bitcoin ATM. There is not a single alternative service in the world that would have made this possible.

And this is reason enough to replace all other currencies with btc ? Because it's fast ?

If people thought a little beyond their personal use cases, they would understand the NON utility of Bitcoin/crypto for most

This technique does not have to work 100% of the time to be effective at what it does. Even at 80/20 it's great at preventing random folks from adding you to meetings. Effectiveness of this technique is better the larger the company is.
