Let's say Youtube's theoretical solution labels you as a child, even though you're not. Without some kind of way to get around that block, you've now lost access to Youtube.

Note that this scenario isn't entirely theoretical. It's rare, but there are already subsets of Youtube (trailers for horror movies are where I see this most often) that are locked behind a login screen because the uploader has indicated they're intended for mature audiences. You either log into Youtube (sacrificing some privacy) or you just don't get access to those videos.

This ends up being not a huge problem today, because the amount of content falling into that category is very narrow. Imagine a world where you fail Youtube's theoretical privacy-preserving test, and suddenly you can't watch anything, regardless of the content, that isn't designated as being specifically directed at children.

Of course, on some level that's just Youtube's choice. But now imagine if a government agency like the FTC dictates that every large Youtube-scale platform has to implement this test. Suddenly you find yourself not only unable to watch videos on Youtube, but also unable to make a Facebook/Twitter account. Imagine if you can't search for certain things on Google.

Note that this final scenario also isn't entirely theoretical with the FTC. My reading of the comments that the FTC commissioner has made is that the value of targeting Youtube is specifically that it's a centralized choke-point for this kind of content. I don't see any reason to assume that if creators migrate off of Youtube, that the FTC won't follow them and impose similar rules wherever they end up.
I think most people would prefer having a "referral" for dates (I know I would at least).

The cost of bad behavior is much higher if there's a third party involved (i.e. you're not just burning with me but also the person who introduced us).

Online dating on the other hand can be a cess pool of poor manners, since there's no social penalty for ghosting your date or misbehaving.

The reason that online dating has been on the rise is because it's easy, convenient, and turns potential suitors into a commodity.
I was thinking someone ought to write a book, not about how to be smart or how not to be stupid, but about stupid ideas people have about being smart.
sure you can. Anything uploaded to YTKids goes through 1 of 2 processes.

1. it's from a trusted provider, send it on through. Add a complaint mechanism that makes it fairly easy for a trusted provider to be removed from this list (DMCA for content, if you will).

2. it sits in a queue until a human looks at it. Prioritize videos from those who were recently removed from the trusted provider list as a way to dampen the harm from abusive reports.

Suddenly, it's a much smaller problem.
I believe dating via referral is possible, it is more expensive.

It needs cultural support (parents) or more money to pay for a matchmaker.
I've commented this on HN before, but the small farmer is criminally underserved. You can get so much more bang for your buck buying an old tractor than anything new, and there are whole cottage industries that have sprung up making replacement parts. If you go to a tractor show you can get just about any part you need apart from perhaps major body components.

I think a startup making cheap reliable tractors could make bank.
I tend not to give strangers with significant financial incentives the benefit of the doubt.
Speaking from the pov as a former astrophysicist, that definition of redshift is not quite accurate.

While we have observed the universe expanding since Edwin Hubble published his findings 90 years ago, it was in fact the Friedmann equations produced 10 years earlier that established how it would work within the context of general relativity.

The Universe is expanding at every known point at the same time at the same rate. However, this is only an observable effect over > 10 Mpc of distance (e.g. extra-galactic distances). This is far too large to effect a point particle like a photon no matter how far it travels so I'm afraid your analogy of a rubber sheet is incorrect.

The lengthening of said photon's wavelength comes instead from doppler expansion due to the nature of differing relativistic reference frames.

According to our local reference frame, doppler effects of nearby stars and galaxies are only due to local motion such as Andromeda being blue shifted as it approaches us for our eventual merger. However, as you go further and further out from our galaxy the metric expansion of spacetime begins to dominate the relative motion of all bodies, leading to observing progressively redder and redder light curves. A galaxy billions of light years away is perceived to be moving away from our reference frame at a significant percentage of the speed of light!

However, if you were to change our relativistic reference frame to match a distance galaxy's you would not see its photons "stretched out" but in fact they would look completely unshifted despite having traversed nearly all of spacetime, expanding as it went.
Extreme hubris, like food safety regulations? Car safety regulations? Right to repair laws? Truth in advertising laws? Bans on toxic chemicals in paint and toys? Worker protection laws?

All of those things, people could have simply chosen not to buy, or not buy from companies employing those practices, yet it took laws (i.e. collective action and organization), to affect them. Telling people to limit themselves to "simply not buying", is telling them to only use forms of protest that have been repeatedly proven not to work.

Don't like companies hiring paramilitary squads to kill union members [1]? Just don't buy Coca-Cola! Spend hours or weeks of research for every minor purchase or risk funding something abhorrent - just God forbid you pass any laws!

This is my take:

-It would limit your possible mates based on your circle of friends.

-Some people want to keep their dating life quiet as involving others can sometimes stress out the situation.

-If things don't work out there is less risk of gossip within your group.

Not having read the article but having participated in Bitcoin "production" a decent amount[1], I see a lot in common between Bitcoin and the organization of the intentionally non-hierarchical Quakers.

Quakers, despite being religiously-motivated to pursue non-hierarchical expression[2], necessarily adopt organizational structure: committees, clerks of committees, group decision-making about who will take certain roles, i.e. "meetings for worship with attention to business." There is some natural and arguably necessary inclination toward roles and authority for the sake of organizational clarity and efficiency.

What it does not have is empowered leaders with explicit authority, rather positions are cast as being in service of one another, in organizing groups of effort rather than controlling the outcome of the group, and thus tend toward eliciting the active participation of all. Care and attention are taken to minimize the gravitation toward arbitrary and unaccountable authority.

Bitcoin takes a similar approach - necessary roles expressed in service of one another / the general effort, with attention toward guarding against arbitrary or negative expression.

The other side of this relates to thought leadership - in some sense speakers naturally have authority via the Pareto Principle's natural tendency to distribute virtues unequally. However, by embracing a consensus-oriented development practice, the general perspectives are a check against individual mistakes or abuses by those empowered by position or circumstance.

I think maintaining the balance between the gravity of centralization vs the beauty and safety of decentralization requires a continuous effort. Thankfully, it is not solely up to the developers to ensure this - developers, node operators, and miners can each and all be active by refusing to upgrade or otherwise by forking the codebase. I would say that's the key ultimate check against the centralization, that every individual has the ability to vote with their node / personal activity. I'll be curious to hear if the article addressed any of that.

I learned enough Python for the interview questions specifically for this. Based on my (obviously anecdotal) experience, candidates I interview spend considerably less time on actual coding when using Python.

That being said, Scala makes design questions much easier thanks to its type system.
Yes, true, and as the paper points out they are related. But the mining centralisation story is basically "water is wet" in 2020 for people interested in this. And as a many commenters here show, the mining centralisation problem is being thought about in technological ways ($BUZZWORD)...

The paper seems to focus more about the political/organisational problem, which to me seem more inherent and harder to solve.
My confirmation emails contain zero product information.
In my opinion, Masters of Doom (as an audiobook) went from good to exceptional because of Will Weaton's narration.
Imagine if every time a nerdy news site got popular and influential, a whole group of astroturfers descended on it. At first it would be companies with commercial interests (and sometimes the nerdy news site would even be formed by a company as a kind of place to express and maybe influence opinions). As the nerdy news site became more and more popular, the news stories would shift from highly technical issues, to more political ones. Over time, the comments section would start to become more polarised as people rallied to support their chosen points of view. Conversations and ideas would carefully be stoked or extinguished by people wishing to push the concensus view in one direction or the other.

At some point it becomes really obvious what is happening. Anybody who lived through the rise and fall of Slashdot has already seen it. However, before it becomes really obvious, is it actually clear what's going on? Does one really understand one is being manipulated? When one jumps into a conversation and pushes an important point, is it obvious that the point originated at this very nerdy news site? Are we all clear on how we formed our ideas, who influenced us and where we got the supporting evidence to convince ourselves that we've got it right? Or do we rely on our gut feelings and participate in the echo chamber?

I don't believe anybody really understands the extent to which they are manipulated. That's the nature of manipulation.
“Does that mean Iran is now racing to develop a nuclear weapon? Probably not,”

Not really sure what the point of this article is, with the amount of reasons they gave in this article you could just as easily say “probably so”.

Why wouldn’t they? And why would they publish the real numbers if they were?

If they are within striking distance of someone else who does have the bomb then they damn well better be making them. Someone put me in check here but I think this fact has more substance than this entire article...
“ It’s unlikely that today’s gene therapies would have serious psychological or metaphysical side effects. They typically act on only one gene out of a possible 20,000 in a fraction of a patient’s cells, such as retinal cells or immune cells.”

Um, that’s exactly the concern with off target effects present in current crispr tech. There’s a lot a hopeful kool-aide in this article.
They have approximately the same fat content as animal products. But not cholesterol.

You probably wouldn't eat an animal burger everyday, so you probably shouldn't eat one of these daily.
Will Bright Star Betelgeuse Finally Explode?
Our moral intuitions are almost entirely determined by the society we live in. 30 years ago, 30% of people in the US supported gay marriage, and now it’s over 60%. Do you believe the number of good people doubled during that time?

I’m gay, and to me the animal farming industry is obviously more wrong than banning same-sex marriage. Yet almost everyone in both of the political tribes eats meat.

My values fall in line with the left in most areas, so I generally associate and agree with left-wingers. This means I get exposed to a lot of left-wing perspectives and media, so to me, it appears that the Republicans are constantly being evil. But then again, everyone on both sides is eating meat, so how different can they possibly be?
Not really. Although some forks are specifically programmed to require a miner vote, that's not the default case, and isn't how bitcoin cash, sv, or the etherum upgrades have worked. It's not very common these days.
How’s this different from a school exam preparation tool? It won’t teach you the subject; and if it did then what’s the harm?

Ontario sits at about 2/3 nuclear. We have for a long time. And our electricity is relatively cheap.
It is valued more in more consequential fields. What cosmologists believe never has any legitimate effect on public policy, except to the degree that they command budgets for telescopes, accelerators, and detector arrays.
> - it's not a breaking change to introduce or realize there are more constraints.

These breaking changes are allowed precisely because they're meant to address soundness concerns. Even if at any given time they're just a "best guess" of what's actually needed, that's still wildly better than what e.g. C/C++ do, which is just to not guess at all. Even wrt. formal memory models, perhaps the most complex issue among the ones you mention here, C/C++ only got an attempt at a workable memory model with the 201x standards (C11, etc.). It's not unreasonable to expect that Rust may ultimately do better than that.
You clearly have never seen the type of content psychopaths splice into child targeted YouTube videos or you would not be making this argument.

We are not talking about some mildly offensive or violent behaviour. We are talking about things that would be illegal to show on prime time TV (child and adult timeslots)

10 great child videos does not make up for 1 psychopathic murder scene spliced into video 11
I would probably agree on that. My limited experience is that the European teams and engineers are very productive.

Maybe Europe gets better engineers there because of less options.
I second Surely You're Joking. There's a second Feynmann book - "What do you care what other people think"
This certainly brings back some nostalgia. The university group I worked with back in my college days in the mid 90's used Pegasus mail. Reminds me of simpler days of school work and a summer spent upgrading Netware from 3.x to 4.x and moving from Charon to Mercury Mail. Not seen those since I graduated, but glad to see the developer still has active development and support for those programs.

I will try to refrain from being anecdotal here, but some of it will leak in, I’m sure.

Boot camps usually strap in their students for about 3-6 months and make them learn extremely basic coding in some modern stack with html/css.

Depending on the company, this may be a better/cheaper alternative to starting talent that was in the grinder for 4 years but may not have any other business knowledge - or sometimes lack knowledge aside from c++/java. (Not arguing the merits here, personally I prefer depth of understanding to a mechanical and superficial understanding, but business needs do differ)

So is it fair to say boot camps are stealing your money? The same way that any for-profit educational institute might. At the same time, they have a similar function to other educational institutions in that they are largely a culling mechanism and not an educational one - but that is a problem across the board.

It’s unfortunate that they market and promise what they do, as it’s just unrealistic - but that doesn’t mean that they don’t do anything. I don’t have the data anymore, but from multiple cohorts what I saw was a slightly skewed bell curve, where the top of the class (~1 out of every 10 or so) tends to do well and find a decent entry level job in 3-8 months, the bottom of the class just flatlines and really don’t learn a thing (1-4 of 10), and the remaining hustle hard to break into the industry for ~2 years or decide it’s not for them.

I haven’t run the numbers, but I know a lot of my college educated friends are not working in what they studied, so for those that ended up not in a code related role, but did not bottom out (I.e. they did learn some basics of how code works), were they scammed by the universities? (Okay, actually, as a victim of this myself, I’d say yes here, but again, I’m just pointing out this may not be isolated to boot camps)

Summary: only go to a boot camp if you have your eyes wide open and know it is a culling mechanism and that if you’re not in the top of the class or exceptionally lucky, you will not have an easy time finding employment. Even the top of the class won’t have an easy time, but it’ll be easier than you. You will probably leave knowing more about code than before regardless, but also be aware of how shallow your knowledge will be, regardless of how long or intense your boot camp is.
See the thread below.

You have a point.

I did not mean that, but didn’t articulate myself in a productive manner.
Yup. Screen timer is a tool to do help break my addiction, which is the first step of the solution (because without doing that first step, I don't think I'd have the mental capacity to deal with the underlying problem).
IIRC it was actually vertically-oriented impellers in a tunnel, but yeah, this is close enough to Red October for purposes of geeking out.
I think it will be different this time. And the reason is that Intel has really dropped the ball. Even if Intel’s chips are better, they have had massive shortages over the past few years. If you aren’t buying 100s or laptops a week, there were periods where Dell would not sell you a modern business laptop at any price because they didn’t have Intel chips.

I’m hoping the system integrators have learned their lesson and go out of their way to support and promote AMD for their own sakes.
It’s about privacy not content.

"The most damaging thing you learned in school wasn't something you learned in any specific class. It was learning to get good grades."

It's really kind of uncanny. I think the root of it is alcohol dries out your skin and causes lots of mid-level inflammation. Smoking is just all around bad for your body (I didn't realize it causes your body to heal about half as fast - although I've never smoked), granted your face is always inches away from a source of smoke.
> how would you prove the inverse of this?

I don't know, but that alone isn't a convincing argument.

> ...ads that would nudge them to a certain political candidate

> ...that's where most of the presential election fund raises go to...

Perhaps. The question is, what is the effect? I would wager it is very small to nil.
> If a detective merely asks you "do you post signs with your name and number with an offer to buy houses",

You're missing the point were the detective specifically asks you if you placed signs on telephone poles and got a voice recording of you admitting you did place illegal signs. The real reason this doesn't happen is simply because detectives can't be bothered, not because it's an impossible case to make in court.
Linux has been improved over the years with patches originally developed by the NSA, and what paranoiac wouldn't welcome that?

That's really unfortunate. I appreciate you sharing that with me. I hope this gets more attention.

But is the BIOS something controlled by AMD or the OEMs? My whole point in this and other threads it that OEMs are handling things poorly, and that's what's affecting AMDs prospects in the mobile market. The BIOS is a highly device-specific firmware, so that's why I'm asking.
> ... His code caused me hell. One production bug after another led me to eventually throw out all of his code. His code was written by somebody who did not care and his tests were useless. ...

We just need different coding interviews. Focus them on systems design, common pitfalls and 'fingertraps', good software engineering principles, etc. A "10x" software dev should definitely know her way around asymptotic O(n) analysis, she might also want to know about all sorts of exotic algorithms and data structures, but there's so much more to get educated about in this field, that could be tested for with relative ease.
Most things that break are electrical, not mechanical. The mechanics of reliable machines are taught in school and are widely available + relatively easy to repair.

And I'm speaking from growing up in a village with the highest agricultural % of population in Belgium. Which my family is also pretty involved with ( my dad is a veterinarian for farm animals, my uncle has ~40 tractors)

Also: a cousin with a garage, some friends who work at a big manufacturer and another cousin who with worked there.

My background influenced my opinion, not a unfunded comment like yours. I am curious what your background is, it's far from reality up here.

Mechanical parts are becoming a selling point. Just no manufacturer realizes it yet, because of "subscription access", lol.

I'd actually buy a mechanical environmental-friendly car. Not some electrical car that needs an overpriced official garage to work on. I want the guy I know, to work on my car. Because it's simple to fix and it didn't need a official licensed laptop to be serviced.

And I'm not alone:

On a personal note, it means I'm abandoning Mercedes-Benz for my next car or have a lease from work.

Ps. All newcomers try full-electric cars. Which have a lot of breaking parts.
>If everyone believes it's there, but nobody knows what it is, well... there was still something that convinced them that it was there.

The article stipulates what convinced these people that it was there, namely that they rested their conclusions on an assumption that turned out to be wrong.

This result is based on the assumption that the corrected luminosity of SN Ia through the empirical standardization would not evolve with redshift.

Which is another good reason not to make conclusive judgements based on unproven assumptions (not that everyone that "dark energy" must exist, but many did, and some people still cling to it even if the face of this study). It is also a good example of why one should never give credence to a theory or a supposition based on how many other people give it credence - stick to what you can prove.
