OK, I'm seeing it now. Generalizing, imagine N+1 jars each containing N balls. The jars are numbered 0 through N. The jar numbered k has k red balls and N-k green balls.

We have N+1 people, also numbered 0 through N. Person k is holding jar k.

We ask each person to draw a ball at random from their jar. If they draw a green ball they take their jar and leave. If they draw a red ball they stay.

We expect on average (N+1)/2 people will remain.

We now ask them to draw another ball.

The expected number of red balls on this second drawing is (N+1)/3.

The expected number of green balls on this second drawing is (N+1)/6, half the expected number of red balls.

That's because on the first drawing, the more green balls in your jar the more likely you will draw green on the first round and thus take your jar and go home. The second round is biased toward people who have jars with more red balls.

Here's the math behind those results. The probability that person k makes it to round 2 is k/N. The expect number that will make it is sum {k=0, N) = (N+1)/2.

Once in round 2 the probability they draw red is (k-1)/(N-1). The probability they draw green is (N-k)/(N-1).

The probability then that they make it to the second round and then draw red is k/N (k-1)/(N-1).

The probability that they make it to the second round and then draw green is k/N (N-k)/(N-1).

The expected number of reds we see in the second round is sum {k=1, N} k (k-1) / N / (N-1).

The expected number of greens is sum {k=1, N} k (N-k) / N / (N-1).

Use the well known formulas 1 + 2 + 3 + ... + M = M (M+1) / 2 and 1^2 + 2^2 + ... + M^2 = M (M+1) (2M+1) / 6 and simplify and you'll get the (N+1)/3 expected red and (N+1)/6 expected green I stated above.

Very funny that Tiktok's response is "we're paying you in exposure!" I dunno man, I don't think that's how music licensing works.
Yep. It's a giant machine with specialized logistics (supplies and parts) and staff needs, so it has to based somewhere. AI can't miracle away maintenance of such a complex beast, if it were ever built. There's no hiding it under a net in the Bahamas.
Be careful what you hope for. For all we know, the answer might be, "Sorry, human, I'd love to chat, but I need to get your dish cleaned and racked up to dry before they close the lab for the eon. Now, how do you get the childproof cap off this bottle of antineutronium..."

$25k in taxes on a $55k income? Where are you from?

For a family in 2024, at the Federal level, the first $29,200 is untaxed because of the standard deduction. The remainder would be taxed at 10-12%. Child tax credits can easily wipe that out and make the liability negative (i.e. you get all your tax withholdings refunded plus another couple thousand dollars).

State income taxes will vary, but are typically lower than Federal income taxes. Many have no income tax.

I have to agree. This is weird as fuck, honestly.

So what you are proposing, and I am perhaps agreeing with, is that someone has created a bunch of random ebooks and then invented a backstory for the fake author?
I imagine it's mostly a CPU/battery/bandwidth concern at this point — having one wireless 4.5k/60 (or is it 90?) stream from your Mac is difficult enough; having a potentially unbound number of them (for arbitrary number of Mac windows open) is a different problem altogether.

But there are 3rd party solutions that will let you do just that though: https://github.com/saagarjha/Ensemble
This reminds me a lot of the fall of the Roman Empire: Romans abandoned the cities and their highly skilled professions so they could move to feudal lords' farms and work the fields. Apparently the society had deteriorated so much that it was more lucrative to work as a field laborer than live in the city doing specialized work. And of course, without skilled people to keep the city's advanced economy going, it fell apart over time.
Its speculation, but probably reasonable speculation. At WWDC, I think almost every OS version gets an announcement of a major version bump. They will announce the next macOS major version, iOS major version, etc. So it is totally reasonable to suspect they will announce the next major version of visionOS.

Edit: But since it is still so new, it could not be until WWDC 2025 that visionOS 2.0 gets announced.
You have zero notion to what the current profit the landlord is making or if it’s anywhere close to “razor thin”.

Yet you pontificated on all the things the increase could be and took the time to get in a jab by asserting it is most likely the op’s fault because they “voted for those policies” yet you conveniently left out the easiest of them all - greed. It’s not beyond the pale for a landlord, especially a private one, to arbitrarily raise prices just because they can.

But, oh no, it must be taxes and crime and everything else under the sun but couldn’t possibly be simple greed. Must be those razor thin profit margins jumping out to scare that most honorable capitalists like the boogeyman under the bed.
You are using the term "OS" to mean something other than "kernel", which is the meaning required by this thread (and arguably entire topic) thus far.

This is demonstrated by the rest of your comment, in which you note that linux has a stable, language agnostic system call ABI, and that other libc implementations exist.

TFA was ONLY about Linux syscalls, so what other platforms do or do not is irrelevant in context.
Diesel subs can also dive because they have batteries and electric motors.
I have received checks in Germany in the last decade, specifically when a health insurer refunded premiums but did not have bank details on file for me.
> It’s definitely not individually trained for each mile in each market.

Oh, that's very interesting. Being in the test/training market, and having read that they were training on every mile while they were here, I thought that was a key differentiator, but if it _is_ generalizable, that's absolutely huge.

(And living here, during training, we'd see trains of 5-6 Waymos cruising down the streets of our neighborhood, so it kind of tracked with what I'd already heard from their videos and posts.)

Thanks for the correction. It's amazing what they've accomplished, and it's also a blast to show out-of-towners who have no idea this is _widely available_ here in Phoenix.
Yeah, please test some in GPT Pro and let me know what answer you get. I have to do some mixed content later this year (Japanese magazines that fluidly meld English, LTR Japanese, and pop-outs in RTL vertical Jap). I've not tried them in Adobe Acrobat yet though, which I usually use for text recognition.
I know the implementation needs a lot to be desired but just in case you were not aware, the Oculus Rift shipped with this feature and it still exists via the link on Quest AFAIK. You pick the last icon on the UI bar that appears and it lets you select any window to pop out separately

Here's a screenshot of 4 windows plus the deskop.

https://pasteboard.co/hPKLrKgp5vjy.jpg

This features has been there for nearly 9 years?

(note: In my view there was passthrough and I could see my room but the screenshot function didn't include that).

It seems limited to desktop + 4 popout windows but I know it used to support more because when I first got the Rift I tried to see if I could get 6 videos running + desktop all at once. It worked.

There are issues though

(1) it's just showing the desktop's image, that means it can't adjust the resolution of the window. Ideally you'd pick a devicePixelRatio and a resolution and it would re-render but no desktop OS is designed to do that.

(2) It's Microsoft Windows, not an OS that Facebook controls which means they're at Microsoft's mercy and whatever features Windows supports. No easy way to add better VR controls. For example, IIRC, you can't size a window directly. Instead you need go to the window showing the full desktop, size it there, that will then be reflected in the popout window. If that's not clear, there are 2 size. The size in VR. The resolution of the window. If the window is a tiny 320x240 pixel window on your desktop and you make it 5x3 meters in your virtual space, all Oculus can do is draw those 320x240 pixels. You can go back to your desktop, size the window to 1237x841, now Oculus can draw those 1237x841 to your 5x3 meter VR pane. But, since Oculus doesn't control windows (or maybe they're lazy), there is no way change from 320x240 to 1237x841 by directly manipulating the pane in VR. Instead you need to do that in the desktop pane in VR.

(3) IIRC it's got some weird issues with the active window. Since it's really just grabbing the textures of the Windows OS compositor and showing then in different spaces, that's separate from Windows' itself's concept of which window is the foreground window. So, as you select windows, you can see on the floating window of the "desktop" the front window keeps changing.

These are all really just a function of (2), that Facebook doesn't own the desktop OS.

The same problem would exist with the Mac. Apple, since they control Mac, could maybe make it work but it would be a huge change to MacOS. They'd effectively need each app to run on its own screen and each screen to be a different resolution and device pixel ratio. Plus they'd need to map in all of the other features to mac MacOS to be usable in AR
I don't think so and , anyway, why are you using the past ? Twitter IS losing money and IS nearly backrupt, not being able to sell , you know, ads, that in a company relying for 75% of its income on ads it's a big problem:

"X generated $4.4 billion revenue in 2022, a 11% decrease on 2021 figures. Revenue is expected to be worse in 2023 due to a loss of advertising revenue"

In fact, now is 1.5 billion verified, 2.1 estimated with a negative trend:

https://www.reuters.com/technology/us-ad-revenue-musks-x-dec...
https://arstechnica.com/tech-policy/2023/12/stop-comparing-x...

We have half revenue, even if you improved the efficiency of 100%, you have no improvement. Besides there are the interest he have to pay to banks lent him money.

So, "He has since turned it into a profitable company" , it's not true, it's the opposite, demonstrated black on white in the financial documents. Everything else is a delusional dream of Musk's troll army.

The people he fired was the same people help the platform to keep away the scum of the web outside, reason why the ads are declining. You know, you don't want nazis, white suprematist, antisemitic, hamas, near the new shoes model you are trying to advertise.

P.S. Anyway why this article is flagged? The source is a news article for a reputable source and the title is correct. Other demonstration that when you dare commit blasphemy against the Cult of Musk , you have to face an overdose of trolling.
It doesn't matter what I believe, the court should have a higher standard when determining legal standing for cases like this. Otherwise it reduces overall faith in the US court system and undermines the rule of law.
You can sell your cars much cheaper if you barely pay the workers and don't invest in safety equipment.
The warnings etc. are for people who, more likely than not, are using a libc implementation that depends upon its own wrapping of syscalls. As such, they are entirely appropriate.

Do they apply to all possible uses of syscalls? They do not.

Is the suggestion then that we need fewer teachers in order for the price of teaching labor to rise above costco? or that we need teachers to provide more economic value from their teaching labor? How do we measure economic production from teaching labor?
Electronic check readers to take advantage of the Check 21 rules. I'm not sure how many places still have them but they were a fixture of large store checkouts 20-ish years ago when the rules came out. IIRC Walmart (and probably other stores but I have vague memories of Walmart...) even had a printer they could put a standard check into that printed the front information (date, dollar amount in words and digits, memo) for you.
And where is Egypt in the global hierarchy of nations? Not very high. This should tell you something.

Some of them have the right idea. There's one guy who built a ship to launch cars into space. He flung one that went around the sun and it was pretty funny. He likes blowing stuff up too.
Please do, because excluding minor exceptions, the more popular of recent programming languages have these as table stakes. Everything (even previously dynamic languages like python) has some form of static typing, options/null-safety, and really good tooling (ts ecosystem is huge, rust compiler has entire articles praising it for making people better programmers). Some languages might be slow to compile but have solutions like HMR for ts and are actively being improved in languages like rust.
I was also surprised it's a TS project. I will say learning Swift and native macos dev during the last year without a job has been quite fun, and a nice departure from web stuff. Swift's type system is very similar to Typescript, and SwiftUI is somewhat similar to any component UI library, but it has it's own interesting bits. Xcode is a beast, but can be a decent IDE after you get familiarized to the quirks of the language and build process.

It takes time to be able ‘see’ the Milky Way. And what made it easy to understand was seeing andromeda through binoculars.

Realising that if I was in andromeda looking back at the Milky Way it would look the same. I could then understand that I wasn’t looking at the Milky Way, but part of it and looking out.

Really grounded me.
Welding may also provide a feeling of satisfaction in that you actually made/fixed a physical tool that satisfies a customer's real need, who thanks you and appreciates your handiwork.
Same here. But I know how they do it because I have some family like that: they're hip deep in debt and will never figure out how bad the situation really is until the inflow of cash that allows them to pay the interest on all of their loans stops. Then there will be a rather rude adjustment in life style.
> State management is probably biggest concern - there are at least 5 approaches / libraries competing for mind-share - and none of them are particularly ergonomic.

I've heard this critique a lot (particularly about Flutter), but I'm not sure I agree that having multiple state-management approaches is a bad thing. Can you elaborate on why this is painful?

From my perspective, (and to borrow the 'ergonomic' metaphor), it's like opening a toolbox and finding 5 different screwdrivers with similar heads. Some might not be well-suited to your project, and of those that do, one might have a handle that you find more ergonomic. I find it hard to imagine a screwdriver that could fit all screws and feel amazing in all hands at once.

Also, fwiw, I find Riverpod to be very ergonomic ;)
> on any other network

> I didn’t even use my iPhone in the US

So you can't really describe the experience for the several different US carriers which it didn't work on, and thus can't really say it worked on any other network. Verizon was a network it didn't work on, and thus fails the "any other network" standard you set earlier.

They are only exempt from the yearly quota (aka 'cap'). They still result in foreign talent being brought in so if your concern is about displacing the labor pool that still applies.
In absolute sense, yes. But in a relative sense the portion they spend on housing is going to be much smaller than what your 'average income' person spends on housing. On top of that they probably own their properties outright whereas the average income person ends up paying interest on the bulk of the price of their home for decades.
> However, internal domains should have their top domain externally registered and controlled

Not necessarily. `.internal` exists for that purpose, and people have historically used `.lan` for similar purposes. There's no particular reason internal names need to have resolvable DNS names of any kind, if they're not going to be externally accessible, unless you're trying to do something like dns-01.
Baltimore has no money, ain't nobody paying for that.

In cities outside of Baltimore, where there aren't 20,000 abandoned buildings (when last I lived there), where there's a public housing shortage and a rising cost of living, they need affordable homes, not trees. I love trees but they're better for cities that don't have housing shortages, yet have the money to pay for trees.

Baltimore (and Philly, similar in some respects) has large concrete and brick deserts. But they also have large and small parks with lots of trees. That's where you get mugged after dusk (and sometimes during the day). You don't walk through Patterson Park at night.

IMO it's a privileged thing to think of first. Certain websites that cater to this kind of post don't seem to discuss civic issues from the perspective of the people who need the most help. It's more a certain kind of person who's more interested in a closer walk to the Starbucks and Trader Joe's.

> Isn't that proof by practice that the underlying mathematical model...

Maybe. Maybe not. The only practical example we keep seeing is implementations centred around SQL which, while loosely based on the relational model, notably does not have relations. Without relations – the idea that sits at the very core of the relational model – you don't technically have a relational database (even if we colloquially call it as such).

So while, in theory, the relational model should work just as well, practice hasn't attempted to prove that at scale. Not since Postgres was first created has anyone really even tried to implement the relational model, and Postgres soon gave up on the idea and moved to SQL too. It may be that tables are actually better for practical use and that the relational model would fall down flat if we ever gave it a serious go.
People come in on a short term basis. They don't know the company, the business, or the employees. They make long term decisions by applying generic and simplified metrics without deep understanding.
If you gave $1000/month to everyone, it wouldn’t necessarily push rent up by $1000. Supply and demand still holds, people have an extra $1k to bid up rents, but that only applies if supply is really tight. In reality, rents are likely to increase not by that much.

If you pay for the $1k via progressive taxation, then it will make the lives of people at the low end a bit better, at the cost of making high end a bit worse.

The only way to make everyone’s lives better is to increase supply in the supply and demand equation, we get that via improved productivity, which happens via better jobs where your time is worth more.
Why do you think teaching at a university is better than working at Costco? How do you decide the optimal number of university teachers vs. optimal number of Costco employees without the market test?

I don't have any emotional attachment to university teachers anymore than I have emotional attachment to buggy whip makers. Maybe a lot of the knowledge a university education provided can be obtained by moving to a major city and watching various Youtube documentaries for 4 years, augmented with debating people in Hacker News comments.

If your goal in life is to be happy, healthy, and fulfilled in purpose, hasn't universal university education been a recent phenomena, not required to fulfil one's life goals? Perhaps university life and its requisite bureaucracy is an aberration, not a requirement for human flourishing.
Same with one of my teacher in France. He had a few patents used in the automotive industry and nade more from that than from his salary.
It will not in fact use the same nuclear reaction as the Sun.

Nor is it being large a good feature. By the square-cube law, it ensures the gross volumetric thermal power density of the thing will be absolutely abysmal, 400x worse than a commercial PWR's reactor vessel.

Value chains – method for creating and balancing faucet-and-drain game economies
Maybe they are different versions, or I'm an outlier, but I love epic - I used a relatively new build of the software last year for a new months, just the ability to message other staff in the context of a patient's chart saved huge amounts of time and interruptions. They also had this super low friction way of addending to the chart, so you could, say, review a (paper) ECG and start recording your interpretation straight into the correct chart within a second or two, and be done in around 10 seconds (with dicatation software which is usually from a different company but integrated)
I had the same question but the interpretation they're considering is whether the next ball you draw will be more likely to be red than the red ball you drew was likely to be red before you drew it but after the total number of red balls was already determined.

Like: you have a box with a whole bunch of red and green balls. Would removing a red ball increase or decrease the likelihood of drawing a red ball from the box in the future?

I wouldn't buy that as a reasonable misinterpretation of the question in most cases, but I don't know what standard of analysis holds for Twitter polls.

I think it's a matter of knowing that the phrase "where n is chosen uniformly at random" means something very different in a probability question than "where n is an arbitrary value".
I'm building a medium sized app in Flutter right now. Occasionally I notice animation lag in development, but in production it is really smooth.
There are a lot of books, and online courses. Given the breadth of topics in undergrad physics, may I suggest materials from MIT Open Courseware?

https://ocw.mit.edu/

My theory is that you can get a sequence of courses, or at least the materials for them, that are consistent.

I know this doesn't really answer your book request, but by perusing the online courseware, you might get an idea of which books are recommended, and maybe even contact the instructors.

It's a lot to tackle on one's own, (I tried, with some grad level physics. Ouch) so I hope you can find a physics grad to help you over the rough spots.

Eager to see what others recommend.
