It's totally counterintuitive. Classical angular momentum requires a choice of origin. All angular momentum is then relative to that origin. Any point particle lying at the origin should not be able to have any angular momentum.

Imagining the classic "figure skater experiment", the figure skater speeds up as she draws her arms inward, due to conservation of angular momentum. If she could shrink down to a point, her angular speed would tend to infinity. This is what I imagine happening to a black hole.

This is a perfect example of nootropic dystopia: paying for a small advantage in a mostly meaningless unproductive task with possibly maladaptive permanent changes to the brain.

Of course this is not new. Ritalin has been used as a study drug for meaningless academic tests for decades.

But it really goes beyond drugs. The experiences created by media and games today, even social app feedback loops, are far more powerful than any real-world experience. Go to bed every night with a show or a game or a social app, and you will lose your edge very quickly. (I’m currently embroiled in a muted partner dispute of several years over this.)

And yet I have considered exactly the same, because the last few years has filled my head with so much crap that I never wanted to think about; perhaps microdosing would allow a more intentional reset, and leetcode may be the closest thing normal folks have to productive mental engagement. Certainly not most jobs, even in tech, which is sad.
SPOILERS:

From a technical standpoint, I was disappointed in the finale. It was too outlandish that they accidentally developed an AI that could break all encryption. In real life, it almost certainly would mean that the technology gets sold off to a military enterprise. Sure, you could say something about them deciding to kill it in preservation of a free internet, and I think that’s the message they were trying to send.

Going into the finale, I had expected maybe they would open-source piper-net. I think it could have made a far better statement about sharing technology, and could have projected a far brighter future, rather than Richard losing his flash drive...
There's nothing ironic about this. The people who don't want growth are rich techies with a 'screw you, I have mine' attitude, or aren't working tech jobs, and the only growth they are enjoying is of the rent they pay for their shoebox apartments.

The former don't want growth in the form of more housing (It devalues theirs), and the latter don't want growth in the form of more jobs (Because that just means more rich people to bid up the cost of their housing.)
My view isn't full of praise. My family was really affected by the recession he caused. The recession was brutal and lots of people never worked again - it caused a lot of pain and despair.

Everyone talks about how taming inflation is so wonderful. Taming mostly benefited the wealthiest - as interest rates have tumbled asset prices have soared in value. Ever since working people's salaries have stagnated. Ironically now people are worried about deflation.

I think that's more of a side effect of a population increase. Though as we've seen over the past few decades, the most advanced societies tend to have a decrease in birth rates after a certain point. I don't think we should be striving to turn the entire Earth into Kowloon.

Anything over 250k is not a typical salary though, even in SV land. It is definitely attainable, but most engineers will never see that type of salary.
While that certainly gives some signal among the noise, it is also heavily skewed towards Twitterable papers. Clickbaity papers fare better.
The definition for structural racism according to the article:

> Structural racism refers to “the totality of ways in which societies foster [racial] discrimination, via mutually reinforcing [inequitable] systems...(e.g., in housing, education, employment, earnings, benefits, credit, media, health care, criminal justice, etc.) that in turn reinforce discriminatory beliefs, values, and distribution of resources,” reflected in history, culture, and interconnected institutions (Bailey and others, 2017).

I think I might be misunderstanding, but given this includes “culture”, is this so sufficiently broad such that hypothetical scenarios such as this (no idea if this is accurate) would be captured “white people are culturally more likely to use crystal meth than other racial groups, ergo they are victims of (a certain kind of) systemic racism”?

It seems like this is just a catchall for any kind of error associated with a racial group, and the article is merely cautioning against such errors. If so, it begs the questions “why not just say so?” and “why use such a loaded term like systemic racism?”.

Absolutely not. This will take away one of the greatest advantages of working remotely, which is being free from distractions and free from having to worry about other people looking at you.

If they want to talk to me they can ping me on IRC (yes we don't use the newer stuff) or schedule a phone meeting. Video calls are only for very specific reasons.

Is the company in any way owning the server or proxying the video or a man in the middle in the communication between you and your peer? My company would absolutely do that, or consider that I can't talk about confidential information through this channel, rendering it useless. And if they do the man-in-the-middle approach, then I would be concerned over privacy of having the monitor me 24h.
>See also places like the North Slope in Alaska, where living conditions are rather harsh but people take the work because of the extraordinary pay.

There certainly are jobs that some mostly younger people take with the expectation that they come with sort of a lousy lifestyle but they'll put away lots of money and they'll do them for a fairly limited length of time. (A lot of these jobs are in the oil business but it arguably also applies to things like investment banking and Big Law where you pay your dues for a few years and either make partner or get out.)

I'm not sure how many people working for big tech companies in the Bay Area have that sort of mindset though. [And, as root_axis notes, I'm not sure the numbers work for most developers starting out. One difference with the North Slope, etc. example is that you don't have a lot of expenses with those kinds of jobs.]

Do you think this would split the existing PAR user base, given that the pros don't matter much to those users (recursive directory blah blah... just create a zip file) and the cons (can't replace a missing file) matter a lot?

It's an eccentric user base to begin with, of course. Most archivists and ordinary users just create multiple backups, and the file integrity concerns aside from file sharing and archiving are best addressed at the filesystem level.
The PC is an extremely refined instrument with excellent flexibility. Billions of hours have been spent training users in how to type and click with a mouse/trackpad/trackball and navigate operating systems. It will take something vastly superior to replace them.

With respect to productivity and usefulness, touch screen devices are mostly inferior, aside from being very mobile. They have little to no tactile feedback, are laggy, and controls can change even as you are inputting them. I've very often tried to click a button/hyperlink on a touch screen and had it change at the last half second.
What is the practical difference between blocking an ad, manually skipping an ad, and watching an ad and then ignoring the product? In all three cases you're mostly worth the same to the creator: zero. This is especially true in worlds like podcasting, where promo codes are the primary tracking metrics to find out how successful the ad campaign has been.

Advertising isn't magic. Your creator is getting paid because they are encouraging users to either spend more or to direct their spending at a specific product (regardless of that product's actual value). I don't see how you're supporting a creator just by listening to ads. The people who buy the products are supporting a creator, and they're subsidizing you. Even to an advertiser, ultimately, your ears aren't valuable. Your money is valuable. A conversion is valuable.

There's this idea that if we all tolerate certain kinds of advertising, creators will get paid and nobody will have to lose -- but it just doesn't click with me, no matter how much I think about it. The money isn't free, it has to come from somewhere. Somebody has to have their spending habits manipulated against their will for this to work. The propaganda has to be effective for some people, or they wouldn't pay this much money to distribute propaganda.

And it's very difficult for me to imagine a scenario where introducing multiple massive middlepeople into that transaction will make the transaction ultimately end up costing us less money than if we just payed creators directly for their content.

We are paying for ads; or at least more vulnerable people are paying on our behalf. I strongly suspect we would collectively pay less as a society if we just gave creators money.

You should take a look at Processing 3 (a graphical Java). My dad introduced me to it at about 12yrs. All he did was give me a YouTube playlist to work through and it has held my interest till this day.

I would say any framework with a narrow focus on graphics and instant graphical feedback (like SFML for C++) would be great for kids or any beginner. Also, Khan Academy has great resources based on ProcessingJS and even a simple submission board with a community of other young learners.

RE: storing user data in a central server or on device, this feeling is what it must be like to feel old.

I remember developing applications for the pocket PC in the .NET Compact Framework 3.5 era. The advice from the Larry Roofs and Dan Ferguses of the world was simple: you can't assume you have network connections all the time, so get your data locally on the device, and sync it when the network returns.

All these years later, while the devices are much more powerful, the network is still not reliable enough to treat it as interchangeable with local storage. Why stream my music over Google Play Music when I know that the hand-off from one cell tower to another will consistently cause a few seconds delay in re-establishing a connection and thus my VPN will have to reconnect, and other knock-on effects?

Yes, use the cloud where appropriate, but if your app is useless without a data connection, it (IMHO) likely means that it could be replaced with a mobile website which at least operates under different user expectations.

I'm excited about CRDTs, once someone makes a robust-enough library for 'good enough' CRUD style abstractions for them (automerge may be this, but I'm a no-JS snob), that library will likely take off in usage, IMO.

I'm not saying it doesn't. The grandparent's point was that the gov could spend the some of the $T it spends on the military on healthcare. My point is the gov is much more likely to fund healthcare through new taxes than to spend less on the military.
Ask HN: Which Company to Work For?
Hello HN,

about me: I'm 24 years old and recently switched companies.

Company A:
I do now work for a medical mid-sized company, with a old IT and old structures in a boring job but I do get paid good. 3343 monthly for 37,5 hours a week, with 31 days paid vacation. Working here does not benefit my knowledge that much. (I have the option, to learn while I work, as I have some spare-time between tasks.)

Company B:
I got an offer from another start-up like company, with a very interesting job, doing what I like. They pay: 3000 monthly for 40 hours a week, with 30 days paid vacation. Working here, would benefit my knowledge for my future plan greatly. I would not have that much spare-time between tasks.

Future plan:
I am in the progress to start my own SaaS, this is why the question is tough to me.
I am able to write code and host servers, I do not need to learn much, to start the SaaS but still, I do not know, if I should take the offer or not. I really tend to do so, because I think it is better for my future.

Can you give me advice in my choosing?

>Article claims that the 1995 No Doubt song, Spiderwebs, references Caller ID. Clearly, the song is about an implausible excuse recorded as an outgoing answering machine message, not Caller ID.

You're referring to this part of the article?

>> No Doubt’s “Spiderwebs,” featured a protagonist, Gwen Stefani, who was screening her phone calls—something made easier with Caller ID.

The article is correct, some of the lyrics explicitly refer to screening calls[1]:

"And it's all your fault/ I screen my phone calls/ No matter who calls/ I gotta screen my phone calls"

In common parlance, that means checking who's calling you before deciding if you'll take the call, which involves Caller ID. [2]

I don't know where you're getting the song being about implausible excuse from the caller -- the song is about Gwen not wanting to talk to someone who thinks she's interested (and Genius confirms):

"You think that we connect ... Your words walk right through my ears/ Presuming I like what I hear".

And later in verse 2:

"Don't have the courage inside me/ To tell you please let me be"

If you're referring to the "a likely story", look at the surrounding lines:

"Sorry I'm not home right now ... So leave a message and I'll call you back/ A likely story, but leave a message/ And I'll call you back."

That is, she's recognizing that her claim of not being available is implausible.

Finally, my love of that song paid off on HN!

[1] https://genius.com/No-doubt-spiderwebs-lyrics

[2] EDIT: A now-deleted reply pointed out that at the time it wouldn't be understood as referring to caller ID, as it wasn't very common to have, and most people screened by listening to the message. I stand corrected.

Still, the article only says that screening is made easier with caller ID, which is correct, and the song is still about screening calls because of unwanted attention, not, as was claimed, about the implausible content of said message.

> I do wonder what will happen if mortgage rates return to even their pre-Volcker level, much less the 1980s levels

It's a scenario that can't occur as far as the Federal Government's solvency is concerned.

Just 5% on $50 trillion in public debt, 20 years out = fiscally say goodbye to the US military and Social Security (or say hello to the highest taxes on earth). Even 3.x% on $35 trillion in ~10 years starts to become a figure impossible to manage as it explodes the budget. You can plainly see the limits on where the Fed can allow rates to rise to.

Instead, the Fed and government's only option is to do everything possible to hold rates down forever. The Japan model reveals some of what the US is going to face, most likely. It's also why US growth keeps persistently sliding lower as we keep taking on more public debt, the debt is putting our productive capital into perma cold storage, robbing the economy of dynamism until we hit zero expansion. That debt will gradually yield less and less, we'll have $40+ trillion yielding 1.x% eventually. Effectively a massive pool of permanently dead wealth stripped out of the economy that will never be put to productive use; and that process of removing money from the economy simultaneously is what helps prevent traditional inflation from soaring despite the low rates. Picture reversing that and rapidly injecting that $40 trillion of dead capital back into the economy and see what would happen in terms of inflation for example.

Yes! Also, long-term owners who bought while rates were high stood to benefit greatly as interest rates came down and home prices rose accordingly. (In your example, your $65k @ 8% house becomes a $100k house where you've refinanced down to 4%.)
You're correct. You can't tell everyone what to do. Therefore you delegate and add middle management and have overarching goals.

Telling a narrative that everyone can interpret willy nilly and pick and choose the bits they like is basically "hoping" things go as you imagined them.

You need hope, but you also just need to check and follow up.
