Q: In the monty hall problem, how does opening the second door skew the probability in favor of the initially unchosen door?

A: The Monty Hall problem is generally poorly described, in order to make the conclusion seem more surprising then it is.

The actual Monty Hall game — as imagined by the people who are asking the question— is set up like this:

In front of you are 3 doors, there is a goat behind two
of them, and a car behind the other one.

In *round 1* of the game, you select a *pair* of doors,
from which *one* “goat containing door” will be
*automatically eliminated from*, leaving only *one* door
of the selected pair of doors in play, (and only *two* of
initial *three* doors in play).

In round 2 of the game, you guess which of the two
remaining doors in play has the car.

The choice is this: should you choose the remaining door from the pair selected in round 1, or should you choose the door which was not part of the selected pair in round 1?

When phrased like this, the answer is fairly obvious: the pair of doors contains a car 2/3 of the time, whereas the non-paired door contains a car 1/3 of the time.

The Monty Hall problem— as normally described— messes this all up by introducing a game show host. This is an agent who— seemingly by their own whim— changes the game you thought you were playing, and introduces round 1 of the game once you have guessed the door you initially think the car is behind. The rules this game show host agent are following are almost never described to a sufficient degree to ensure the game is equivalent to the game laid out above. And yet, the people asking this problem pretend that it is exactly equivalent when they ask you for an answer.

It’s generally a poorly described problem, whose answer depends entirely on what kind of agent the game show host is.

Don’t worry if it doesn’t make sense to you as it’s usually described. If you can understand why— in the two round game I describe above— it’s better to pick the door from the pair of doors, rather than the single door, you understand probability just fine.
You could pick something like shocking the fingertips. A sensation, but not one expected to quiet the chronic ringing.
I mean we're talking about a car that literally has the risk of its roof blowing off. How can that NOT be the end-all-be-all?
The AFL are the guys I allude to in the story of Avalon/Peru/Excelsior. Those who would flip from enemy to friend when they are weak can flip from friend to enemy when they are strong just as easily. I'm willing to believe, but no core tenet of the AFL-CIO is considered immutable. Given that, and given that they shift with the breeze, perhaps you can see why their words ring hollow.

Today, they feel this. When tomorrow they must cast us aside to win something more essential to them, will they stand strong? They didn't in the past. Why would they now?

Even 2 million strong they are subject to Stolper-Samuelson.

Hawking Rings, Delayed Choice Double Split Experiment and Fermi's paradox imply that the universe came into being and time started when a quantum superposition was in a place where if collapsed would create humanity.
Perhaps an imperfect allusion, given that most Abrahamic religious services involve recitation of prayers and affirmations that restate basic principles about the identity and nature of God.

When has a modern day labor union operating in the tech industry harmed you in the past?
46 vs 37 is most colleagues. Nobody is forcing you to stay at a job where management makes decisions that you don't like, and similarly no one is forcing you to stay at a job where it's your coworkers making decisions you don't like. This is what democracy looks like.
You are comparing very different classes of cars. A Tesla Model 3 is equivalent to BMW 3 series ($35-40K), and in my experience compares very favorably to it in terms of performance, design, servicing/maintenance and more. Owning an entry level BMW isn't the luxury it's claimed to be in ads. A Porsche Taycan goes for $150K+.
(Replying after your clarifying edit.)

You seem to have a very narrow definition of what "love" is and want to deny people the ability to love in whatever way makes them happy, which is a bit uncharitable of you.

I think maybe I get the root of your complaint; there are some people who drink the kool aid and get stuck in what amounts to an abusive relationship with their job, and stay there out of some sort of warped "love". That is genuinely bad. That is also not what anyone in this thread is talking about when they say they love their job.

I have at times loved my job. I have at times only liked it. And sometimes actively disliked or hated it. I've also loved romantic partners, family, and friends. My love for a job is different than my love for a romantic partner, which is a different love than the love I have for family, which is also a different love than the love I have for friends. That doesn't cheapen the value of any of these kinds of love, and neither does broadening your horizons to accept other kinds of love that you perhaps don't feel yourself.

There are many different kinds of love, and no person has any business telling others how to love or how not to love. This has nothing to do with "conditioning" or "defensiveness". You just don't get to decide this for anyone but yourself, and complaining about how other people love is as meaningless as complaining that the sky is blue.
The high-paying locations are the ones where the experts congregate.
Yes I finally understood it. At the beginning you are choosing one door vs "the others". If you could you would already chose "the others" because they have a 67% win probability but you are only allowed to chose one single door. Then he opens all the wrong doors of "the other doors". The "other doors" still have 67% probability and now only one door is remaining in the "other doors". Obviously that last remaining door now has 67%.
Concorde was profitable. It initially wasn't, but then BA and Air France found out that customers thought Concorde was more expensive than it actually was. Once they increased prices to customer expectation the Concorde was fairly profitable. https://theadaptivemarketer.com/2012/01/14/a-pricing-lesson-....

The major issue with Concorde by the time of its retirement was that it was very old and outdated, among other things needing a 3-person crew. The market for new Concordes was not large enough for a next-egeneration update to be profitable. And 9/11 had dented air travel demand.

Simulate it.

I thought as you think. I wrote a simulation to show I was right. I was wrong.

I have had this interchange several times. Invariably it goes one of two ways. They have endless reasons why they have to be right and they don't need to write a goddamn simulation, or they tell me they wrote the simulation and they have learned they were wrong.

Yeah. I'm aware of that. It's a bunch of straightforward questions, a pretty high bar for how many you need to answer, and so it's pretty random how many of them you mess up, so it's kind of like a die roll to get a job. I had a really bad interview at a peer company once, and I'm well aware how it goes.

But I kind of miss the old Google where you DID need to be a genius. I interviewed with Google probably around the year 2000, and there was a genuinely hard ball packing problem. I'm kind of curious what happened. Anyone who could answer that question would find this one trivial -- and not just the dynamic programming solution, but the O(log n) one which apparently no one at Google (or even applying to Google) noticed.

What I hate about Google is that everyone there still thinks they're a genius. In 2000, it felt okay, since for the most part, they actually were. Today, it's kind of obnoxious.
yes very nice writeup by johann
If so, you will find me a trivial recruit and true believer.
I think the speed advantage is more due to the I/O controller that Sony's made a big deal of, where data can get to RAM or GPU without having to interrupt the CPU. Those interrupts can cause a domino effect with Windows doing god-knows what else in the background, leading to a stutter.

You're right though, PCs will get brute-force faster, while devs will squeeze more out of consoles. I just find it hard to make the case for building something right now given the apparent bang-for-the-buck of these consoles. That said, I do kinda need a new Plex server... :)
True, video chat is very expensive especially with the extreme bandwidth costs of the big cloud providers.

I built something similar as OP and chose a mesh solution for this reason even though it's inferior.

It appears that only big video chat companies like Zoom or Skype can afford to have a generous free tier, subsidized by their business offerings.
Can you tell us what you love about the Model 3 that makes up for all the bad?
To be fair that particular example isn't as terrible as it looks because that's (generally) the intended behavior.
But yeah, this is the type of arcane bullshit that comes up all the times in system-level C programming. C is a great language, but the environment you find yourself programming in is layers upon layers of barely intelligible nonsense that nobody needs nor wants.

This is so true, look at any GM or Chrysler car from the 90's. Complete abominations of cars with cheap plastic everywhere and myriad mechanical problems. You can see their attempts to catch up to Japanese cars during this time.
It might be a little much, but maybe you could numb the area? (although this might eliminate the effect...) or maybe use something like laughing gas to put the patient semi-out (you probably wouldn't want general anesthesia, since that's risky)?

> And an arc minute's area, viewed from low orbit, is somewhat bigger than a football field.

This means if you take a point light designed to light a football field (football fields do have these light sources), and direct it into space instead of the ground, will be visible from low orbit.

> E.g. if it's known that a transmission of a particular chunk of a stream failed, the next transmission can capture that chunks plus additional data from that stream instead of just blindly retransmitting a full datagram.

But QUIC Datagrams do have ACKs, and don't have retries. Maybe we don't want them to have ACKs, but as long as it's opt-in, is that not enough for the upper layers?

> Besides that the crypto and handshake parts also need streams with guaranteed delivery and ordering, since they carry TLS stream data.

QUIC packets are individually encrypted so more metadata can be encrypted too. And I don't think connection establishment uses any sort of stream abstraction either since people speak of n-packet handshakes?

> Yes, because they are being hired to do the same job.

Is it? One could do both jobs (Advanced ML & QA) but I'm not sure the other could.

Question is: Should the job of guard at ToysRUs be considered a specialty occupation?
You can do all of that, except for the application level control, by just opening multiple TCP sockets. QUIC is just basically TCP over UDP in that it shares the same semantics (guaranteed, in order delivery of a bidirectional data stream with congestion control). Sure, game engines don’t always want all those attributes - guaranteed delivery, for example - and will implement their own thing over UDP that makes more sense for them. QUIC is just as bad as TCP for those use cases though!

Not when the configuration is drastically different. "Scale" has a very specific meaning in engineering. It's like saying a motorcycle is a 1/3 scale version of a car just because it uses the same motor. It still demonstrates that the heart of the vehicle works, but it's not a scaled version of it.

Nevertheless we should all be as clear as possible about Googles' motivation for pushing any new technology: Better data collection, more/better/fine-tuned ads.
But it does equal to unemployment in the United States because you can only get limited mileage out of OPT. Moreover, you need to work in an industry where employers are willing to sponsor an H-1B. Many of us have had to "pivot" to industries like Software when we realized that we were un-hireable in non-software industries due to our immigration status.
It's strangely common. As someone who has worked in a few IoT companies that ship devices that run on other people's networks the amount of enterprise gear that just drops all UDP as a default is astonishing. Every single IoT device I've worked on has had some custom, hand rolled, NTP-over-HTTP to get around RTC failures.

Affordable supersonic aircraft seem like a great technological achievement, and I'm all for it.

But would the impact be that high?

Cutting flight time by 40-45% is nice, but end to end travel time includes driving to/from the airport and immigration, which does not change.

Let's look at JFK-LHR (New York - London). The flight time is cut from 6.5h to 3.5h. Let's add 2 hours overhead at each end (somewhat ... optimistic), which makes it 10.5h vs 7.5h.

LA-Sydney is 14.5h vs 8.5h, or 18.5h vs 12.5h end to end.

Is that difference really going to change if you take the trip or not? Would you be willing to pay a significant markup for that?

Seems like the market would be constrained to relatively high profile business travel.

I've been running WSL and then WSL 2 for a while now as my full time development environment, it's quite solid.

This isn't mentioned in the blog post but if you use VcXsrv you can have it start up automatically by putting its config in your start up folder.

That's what I've been doing here for the last year or so: https://github.com/nickjj/dotfiles/blob/master/c/Users/Nick/...

If anyone prefers video about 6 months ago I recorded https://www.youtube.com/watch?v=idW-an99TAM which is about a 30 minute drive by of setting up WSL 2 + Docker + VcXsrv and a bunch of other tools that are handy on Windows for web development.
The current law does exempt APIs from copyright via sensible general principles (you can't copyright functional things, which as applied in this case is known as the merger doctrine).

If the court gets it wrong congress should fix it, but ideally we don't want a law that is a patchwork of tiny little exceptions because that fails to generalize to new things, so we would rather that the court just properly understands how to apply general principles.

Even if the court gets it wrong, my favored way of fixing it would be to modify the general principle to be less ambiguous to this case, not to explicitly make an api exception.
The Xbox design looks classy but uninspiring. I like that. You can sit it under your tv and it will blend in with the style of most rooms.

Intuitively just consider the difference between the two:

What DO you see? In case of the mirror, you see what's BEHIND you, because the stuff in front of you is blocked by the mirror, no? And just to be clear, by "you" I mean your eyes, and in particular the direction your eyes are looking at.

Now in contrast a photograph never shows what's BEHIND the camera (now that would be kind of funky, don't you think?), but - just like your eyes - only captures what's in front of the lens.

And there's your difference.

I’m not sure the doctor comparison holds up here.

The doctor takes your oral history to assess your health. Knowing that $x percent of family tree has high blood pressure means they can more accurately assess your risk of high blood pressure. For the population of “literally you”, your oral history is data. Now, if the next patient came in, and your doctor said “well, the last person in here has high blood pressure, you might have it to”, that’s an anecdote.

Similarly, telling somebody ~”My instance of $product worked great” isn’t really useful info for them. That’s a sample size of 1 out of a massive number.

I'm sure they'd like to, but the line between "vetting" and "endorsing" is extremely challenging to draw, and it's not good for anyone if Facebook bans spreading information that they don't as a company endorse.
> The solution here is to pass a law that exempts APIs from copyright

But APIs were never included, explicitly, in copyright in the first place. Why do they need to be explicitly excluded?
It's not dressing up as science, though.

I understand that for someone who appreciates science, but not philosophy, the book turning out as straddling those two fields might be a letdown. But that's not the authors fault since those books are not presented as academic research, but only informed by it.

Infuriating for me are philosophical discussions which don't draw substantially on science.
If you look at the monitor + stand its actually cheaper than competing pro monitors. I have no idea why they didn't just make the monitor more expensive and the stand cheaper and include vesa holes to avoid the years of jokes that followed that stand.
Ask HN: What is the next Reddit, for you?
Just saw that Reddit has removed Aaron Swartz from the list of co-founders, and was wondering, what online communities do you really like that serve the need for discussion and play which aren’t HN?
Specifically, it's the difference between

var num_stays_wins = 0; var num_switches_wins = 0; for (var i = 0; i < 100000; i++) { const car_door = Math.floor(Math.random() * 3); const my_choice = Math.floor(Math.random() * 3); var montys_choice; do { montys_choice = Math.floor(Math.random() * 3); } while (montys_choice === my_choice); if (montys_choice === car_door) { i -= 1; continue; } if (my_choice === car_door) { num_stays_wins += 1; } else { num_switches_wins += 1; } } console.log(num_stays_wins, num_switches_wins);

and

var num_stays_wins = 0; var num_switches_wins = 0; for (var i = 0; i < 100000; i++) { const car_door = Math.floor(Math.random() * 3); const my_choice = Math.floor(Math.random() * 3); var montys_choice; do { montys_choice = Math.floor(Math.random() * 3); } while (montys_choice === my_choice || montys_choice === car_door); if (my_choice === car_door) { num_stays_wins += 1; } else { num_switches_wins += 1; } } console.log(num_stays_wins, num_switches_wins);

(The difference is in the calculation of `montys_choice`.)
I wonder what capabilities they have versus what they turn on for the general public due to regulation and safety. I would imagine that to release FSD in the wild will require an insanely high factor of safety.
> 1 - 5 bit errors per hour for 8GB of RAM after my calculations

That is way off from what I'm seeing. When launching Factorio I use 90% of my 8GB RAM and never once have I noticed data corruption, and I could tell you how many hours I've played but that would be embarrassing.

The test I did in school with heated-up RAM (the internet said that's when flips should occur more often) also wrote many many gigabytes without a single failure.

Not sure what hardware or temperatures that source is running but it's not DDR3/DDR4 at heats below hairdryer melting temperature because that's where I had to stop the experiment with zero failures.
