> The systems guy in me has experience that all exponential trends are s-curves

A friend of mine visited a financial planner inquiring about saving for his children's university education.

The planner took the last the last 20 years of education inflation and extrapolated it out 15 years, and recommended my friend put away 2.5k per month today per child today to cover it.

My friend didn't hire the planner, on the reason that we will probably be post-revolution (which would cause this curve to become an S) before we get to the point where you need to save 30k per kid per year over 15 years to pay for university.
Unless you go out in the sun. But yes, if you're hot indoors, wearing black clothing can help by radiating more heat. (And white clothing can help in the sun by reflecting more incoming radiation.)
Cancellation still works. I just went through the flow a few minutes ago.

Something like this would do the same, if somebody implemented a tool called jsed:

jsed '
Object.fromEntries(
$("Directory").map(
x => [
x.name + " has children",
x.children && x.children.length != 0
]
)
)'

Interestingly enough there is already a tool called jsed which seems to kind of do this... https://www.npmjs.com/package/jsed

Edit: Note the jQuery part of it is for advanced cases like searching for specific nodes in the tree, then navigating back up to the parent. Basically the cases like "<Work>[-1][children]" from the jtc guide, I would write as: '$("Work").parent().find("children")'
They do/did have a customer satisfaction survey somewhere at the end or after the booking process.

I made sure to provide feedback.

When people book with you but give you 1/10 stars, that's probably a pretty strong warning sign that the customer isn't happy with the site and the first usable competitor that they find will get their business.

It's also a natural tendency to eat calorie dense, sugary foods. That doesn't make morbid obesity any less of a pathological and unnatural culural phenomeon.
>A simple forum also has reply notifications, that HN has not. It is difficult to accept that HN is different from other forum software, with different priorities?

I don't object to the fact that this forum lacks particular features, I can accept that, although I would disagree that they would add unnecessary complexity or would somehow damage the "signal to noise" ratio of the community. I object to the tendency of people here to assume that any features this forum lacks are a priori without value because it lacks them.

If they don't want to add these particular features, fine, but people need to stop cargo culting the simplicity of this forum. Some of the features here are intentionally, actively user hostile and we should admit that Hacker News gets a pass for no other reason than it's Hacker News.

>I don't know what being writing in Lisp implies that HN have to have some specific feature that you think it needs.

I was snarking on the way people sometimes describe how elegant and powerful Lisp is, almost as if it were magic. Sometimes I forget this place is where humor goes to die. Mea culpa.

> otherwise, the your best bet would be to replace a few million square kilometres of a hot region with black paint and make sure there are never any clouds overhead.

That would be counterproductive since black would absorb more of the sun's energy during the day than it would radiate at night. What you'd need is a way to have a black surface during the night and white during the day. (But barring that, white all the time is better than nothing, because it reflects more of the incoming sunlight. This is why melting of polar ice caps can accelerate climate change.)
What about the post history data set in BigQuery? That is a widespread and complete record of HN activity.

That used to be the case; now the new Silicon Valley for producing anything is in Shenzhen with crazy innovation (kinda like what Japan used to be in the 80s). You can set up your own goods production there in minutes and in all kinds of quality as your budget allows. A regular Chinese now matches a regular American in quality of life as measured by typical economical metrics (adjusted for purchase parity, not in nominal value). Many US/EU companies reduced to selling stuff one can buy on Alibaba for 1/10th, just rebranded to appear US/EU-made. There are some areas Chinese can't do yet, like advanced metallurgy, which was generating quite a bit of business for US/EU, but that disadvantage is disappearing rapidly as they continue throwing money on it and invest into research.
This sounds familiar. Here's an article from 2 years ago saying the same thing:

Hopefully this time it's the real deal. I remain skeptical.
It is my understanding Fascism was invented by disaffected Socialists and Marxists who felt the revolution was taking too long.

The opposite statement is closer to the truth: fascism as a reactionary response to Marxism and progressivism.
It was clearly an illusion of safety to begin with if they broke in. At that point you're at least informed, and it didn't cost you anything.
This is a difficult argument to counter; for instance, are you sure that signal can't decrypt your messages? If so, do you remain sure knowing that they can update the app?

As a security person I really can't think of any service (or piece of hardware) which I think satisfies the threat model where the provider is both clever and truly hostile.
Of course, with as much air as comes in the ice cream here, a half gallon is probably only a liter of actual ice cream. They definitely don't weigh nearly as much as they look like they should.
the 80/20 principle says it's going to be a long, long time before level 5 autonomy is reached. That's 100% in all conditions. In fact, I would say it's more theory than attainable.

There's a reason they're testing in Phoenix. It has almost no Inclement weather. Throw a little snow, mud, or sleet in there and it gets hairy fast. Level 2 is basically the 20% of effort in 80/20. It's exponential effort from then on out.

Nitpicking, half of modern laptops consume something close to that, e.g. surface pro 4 36W, macbook air 30W.
I agree. The IRS should simply mandate that forked coins have a purchase price of 0 USD. When sold, the tax event occurs and the seller simply pays the short term or long term realized gain.
Same with best uber drivers.

The generic answer to these concerns is usually the following: if a (well-known, very scrutinized) company such as Google writes that kind of promise in public documentation that is part of a binding contract with paying customers, there is a good chance they won't purposefully break that agreement, and risk being caught by an audit, just for the sake of accessing someone's personal data.
Moviepass was spiraling the drain though, so a desperate move like that didn't seem so strange. Blizzards having a bad week, but they're still a healthy company, and a bizzare attempt to block people from leaving would just amplify their PR problems.

So I'd guess technical issues as well.
Nonsense. Image recognition engines are very capable of detection in even at the most extreme angles. Sure it won’t rotate the image for you but it will certainly tell you there is a goose in it. What tricks image recognition technology more then anything is lighting.
Waymo is so far ahead in this game. Tesla has the biggest online cheerleading section and an "autopilot" that behaves as a low-budget adaptive cruise control with lane keeping that sometimes works, and a pretty big body count. Uber has a dead pedestrian and a major lawsuit. Cruise has a lot of people on staff but virtually nothing to show for it. Lyft exists. Waymo is in production revenue service.

String theory is probably the one scientific topic I spend the most of my free time learning about. It is fascinating. I have read Brian Greene's 'The Hidden Reality' over five times, I think.

I recently watched his conversation with Sam Harris and was intrigued by a point Brian made, albeit about quantum mechanics and the 'many worlds' theory.

Brian claims that he doesn't think the many worlds theory holds water because it makes an assumption about what happens before some object is measured (A) and after that same object is measured (A'): while many worlds claims that all possibilities are indeed realized, Brian claims that we just don't know for sure what happens between events (A) and (A'); he claims that a unified theory would explain what happens between those events.

In any case, that's just me rambling about it. Thanks for the post :)

Make it easy, and you lose some revenue from customers who want out and could be kept in against their will by making it too painful. However, the customers are happy, and you gain their trust. This will make them much more willing to give you their CC# the next time they're thinking about re-subscribing.

Make it hard, and you may keep a small fraction of these customers, but make all of them hate you, make them hesitant to re-subscribe, and make a significant fraction just go through alternative means (e.g. chargeback, cancelling cards, letting a prepaid credit card run dry) that end up costing more than that.

Just so. After having done JavaScript development for a few years, I really can't take the Elm FUD here seriously.

I'm starting to think that there really are a lot of front-end devs who don't know anything but JavaScript.
I ran into this issue while developing https://www.faceshapeapp.com where user uploads their photo and face detector is run on top of the picture. Shortly after launching about 10% of users complained having rotated images, after some debugging, I discovered that it was due to exif rotation.

You could parse the exif and rotate the image using canvas, but thankfully, there's already a JS library which does it for you: https://github.com/blueimp/JavaScript-Load-Image.

Sure, In situation 1 is says the following:

"A holds 50 units of Crypto M, a cryptocurrency. On Date 1, the distributed ledger for Crypto M experiences a hard fork, resulting in the creation of Crypto N. Crypto N is not airdropped or otherwise transferred to an account owned or controlled by A."

So I interpret the line "Crypto N is not airdropped or otherwise transferred", too mean that there are no additional transactions that are recorded on the new blockchain N to give people additional coins, but previous state is maintained, as maintaining state is not a transfer.

An airdrop would have to be an actual state change, "recorded on the distributed ledger", that says "These people now receive 200 coins". In the case of a normal hardfork, there is no transfer that is "recorded on the distributed ledger".

I interpret that as meaning some sort of additional transaction, on the blockchain.

If you notice, in situation 2, the key line to look at is as follows:

"The airdrop of Crypto S is recorded on the distributed ledger on Date 2 at Time 1 ".

It specifically says that something must be recorded on the ledger.

The reason why situation 2 needs to be called out, specifically, would be in the case of a developer, hard forking a coin, and giving themselves a developer dividend, for example. It would make sense why the additional transactions, that are "recorded on the distributed ledger" would need to be taxed, as it is referring to additional coins being airdropped.

Edit:

Ah, you were also referring to this line here:

" A did not receive units of the new cryptocurrency, Crypto N, from the hard fork"

I'd interpret this the same way. The user did not receive any units of the cryptocurrency. They had it all along. It would take an actual state transfer for them to "receive" it.

It sounds weird to say, but basically, they had these coins already.

I don't think you're being very accurate there. There are lots of videos of people commuting 50+ miles to and from work every day without touching anything while on the interstates, including interchanges. It's doing a lot more than just lane keeping.

This will be my last reply since it's quite clear we're at an impasse, but I assure you I have been exposed to many more perspectives than just HN, and frankly am offended that you would assume otherwise. I think it reflects poorly on the strength of your argument if you have to resort to "you disagree with me, you must not be as well informed as I am". Particularly when you proceed to not clarify in any way which perspectives you're referring to, it is a sign of arguing in bad faith.

Your comment reads to me as a very thinly veiled "shut up and dribble" [1]. Not quite identical, mostly due to the lack of racist undertones, but the idea is the same. If the NBA standing in support of democracy and human rights creates an "international battleground", the blame for that lies exclusively and totally with China, full stop. These are things worth going to battle over, whether within the context of the NBA, state department negotiations, or anything in between. Your point about weaponizing the peace corps is a complete non sequitur.

I understand, I think as well as any western person can, why the Chinese get upset about this. I'm familiar with their history of issues with territorial sovereignty particularly in the 19th and early-to-mid 20th centuries [2]. I simply completely disagree that said reaction is justified. People advocating for the right to govern themselves to some extent or another, particularly when the alternative is falling under the jurisdiction of an authoritarian regime, is justified precisely 100% of the time, and anyone who thinks otherwise is simply wrong, or yes, brainwashed. Silver may have listened to other perspectives, but I'll eat my hat if he cared at all about them, as opposed to caring about the NBA's bottom line.

It feels like Hong Kong has spurred a political crisis in Beijing. Publicly denouncing the NBA? Publicly going after a European capital?

It would be one thing to do this behind closed doors. But the hamhandedness of it all resembles flailing more than a coherent strategy.

Is there a domestic nationalistic PR strategy this is playing into?
Yeah. My technical tracks were covered. It was the roommate of one of my friends. He overheard me talking about it and ratted me out.
"People who go to church have values", doesn't mean "People who don't go to church don't have values". He was just using it as an example of how people make (or used to make) friends.

To your original point about drugs helping you make friends, I'd argue that you're making friends because 1. It's a shared experience, and 2. It's taboo, which forces extra trust between you and everyone who joins. Not so much as an effect of the drugs themselves.

Others in this thread dislike that you're suggesting drugs as a way to make friends because, well drugs are taboo. It's not like you can just post "Going to a rave and doing shrooms" as a meetup event online, nor can you invite your wife and kids to go camping and do LSD, so your suggestion is not very helpful for the kinds of people here who would be having a hard time making friends in their adulthood.

Yeah and so is having software being spread across multiple OSes "horrible UX" too, so you are basically suggesting that the Windows monopoly is a good thing for customers in that same vein.

Good to see this finally happening. I wonder how they're going to scale this out though -- AVs are still pretty expensive to build/operate (COGS/TeleOps/Maintenance etc)

Do any of these patents explain how they're converting the fusion-generated heat into giga/terawatts of electricity?

Am I expected to believe there's a turbine propelled by steam conventionally generating that much electricity powering the alleged tic-tac craft?

Or do the patents describe a purely direct thermoelectric conversion method capable of sustaining such power levels in such a small space at fusion temperatures?

From where I'm sitting, at this moment, this all seems like an elaborate disinformation campaign to both prop up morale of the domestic masses believing the USA has magic China doesn't, while trying to instill FUD in the enemy.

Learning to Control Self-Assembling Morphologies
in 1990, while working for an insurance company, we were looking for what UNIX to port a multi user database to, We looked at SCO, Microport, Cohernet and Sperry. The company chose Microport, and the Sperry went back, so I got to keep SCO and Coherent. Loaded and ran both, liked SCO a tiny bit more because of it successfully compiling a few programs, and heard about the UNIX Copyright controversy.

Coherent installed, and ran, but had a few incompatibilities with our software, but ran solid as hell. The documentation was very good too.
