It's ambiguous. The end condition could be a pixel spawning with overlap on a ball because there's nowhere else to go. What will happen when there's no room left to add one more pixel, and it tries to add one more pixel? Will it place it with the collision boundaries on the wrong sides? Will it crash with a null value error because there's no good spot to place it? Can't know without understanding the code. But there are many possible end conditions.

They're asking if one can prove that you never reach any situation where an end condition (intended or not) could ever exist.

Imagine black has a long horizontal 1 pixel tunnel, but it's zigzagging down hitting every side pixel rapidly, while white has a long white tunnel and it's bouncing perfectly horizontally, taking a long time to hit each end. As the ends close in on white, is there some perfectly aligned timespan where black can hit a pixel while white doesn't have a full pixel of open space on either side? It would be interesting if someone can articulate logically why or why not that would ever happen.
It seems to me this article is addressing the wrong problem. If each subsequent generation grows up more ignorant than the last, all the hard won advances of civilization will be lost. People will pray to the few remaining AI terminals like they're deities.
Nothing magical about observation. Seems to have scaled so far. Not sure what magic you think might interrupt individuals' desire to produce more art and science.

> I think we've already passed the point where anyone can keep up with all the cultural output (music, literature, graphical media) that is released each day.

Good thing that's not necessary for one to benefit from it. I, for one, am happy to benefit from all the medical innovation I can't keep up with.
Nah apple just cut costs and hired some year of efficiency designers. Usability will fail and they will need a visual distinction.
Fun anecdote - I wrote a new load balancer for our services to direct traffic to an ECS cluster. The services are exposed by domain name (e.g. api-tools.mycompany.com), and the load balancer was designed to produce certificates via letsencrypt for any host that came in.

I had planned to make the move over the next day, but I moved a single service over to make sure everything was working. Next day as I'm testing moving traffic over, I find that I've been rate limited by Lets Encrypt for a week. I check the database and I had provisioned dozens of certificates for vpn.api-tools.mycompany.com, phpmyadmin.api-tools.mycompany.com, down the list of anything you can think of.

There was no security issue, but it was very annoying that I had to delay the rollout by a week and add a whitelist feature.
Bingo.

The correct answer is that this is a contract dispute, not a state or federal dispute.

The electrical company leases a right of way for the lines across private property. There's a contract in place for that lease.

Does that contract have anything to the effect of "property owner will guarantee a stable, non-interfering electromagnetic environment in this right of way"?
> Sounds like you gave them an unfair value.

Huh?

They were the bidder. There was no haggling or negotiation. Accept it or walk away.
So you're saying that the law should force people to stay in a business relationship? Like let's say this wasn't a teacher employed by a school district, but an independent tutor directly employed by parents. The law should force those parents to continue hiring the tutor? What if the parents have an independent plausible (or real) reason to cease doing business with the tutor?
You can’t stop public use but you can make it so that any account posting AI porn of someone without their consent gets auto reported to the police or at least automatically filtered out. Also I think it’s a recency thing, in a few years no one will care if someone makes AI porn of you other than to get mad at the person who made it if it was done without consent.
That was true in the 90’s when you’d post a whole page but these days the individual checkboxes are more likely to have event handlers that transmit state to the server immediately.
The Sunk-cost fallacy is when you weight the value of something disproportionately because of effort or expense you've put into it.

But if you've got an OS that's certified for the work you're doing, and it's not costing you extra to work on that OS, then there's no fallacy - you're getting more value out of the cost of certification you've incurred, and shifting to some other OS would presumably require you to incur the expense of certification again.

That said, the skills needed to work with a legacy OS will tend to become rarer, so you ought to factor that into your calculations.
Can somebody recommend some music theory book/course for this algorithm or the one in https://www.vitling.xyz/toys/acid-banger/ to make sense? Obviously, there are some pretty simple rules to predict that something sounds alright, some more complicated ones, and baroque music is notoriously algorithmic. But I still have no clue.

I tried to research something across these lines before, and I cannot quite recollect what exactly was the problem with the books I came across on my own (I think it was mostly just too basic to be useful), but somehow I never got any "general" understanding of "how music works". Even though I've got some very basic solfeggio training long time ago (admittedly, I was too young to ask questions I now find interesting and understand what's the purpose of what we were doing there, but at least I can read the notation).
I just double checked and I read my link completely wrong. That's my bad. It seems you're correct.

That just explains why it tends towards balance. It's just like all the air molocules in a room reliably bouncing around where you can inhale them. There's no hard law of nature saying all the air wont move to one side, suffocating you. It's just statically extremely improbable.

"Market maker" is quite a specific term and is typically used to describe companies providing liquidity in a market for a given good/asset/etc. They are almost by definition not speculating, they are in the business of liquidity, and are compensated for providing liquidity.

Speculators would (try to) buy low and sell high, whereas a market maker could well buy high (when speculators are trying to sell) and sell low (when speculators are buying). That sounds counter intuitive, but of course speculators aren't always right, and market makers typically aren't holding assets for enough time for prices to move much, and they make money off a small spread.
Did that have any effect? Usually people lower in the org chart have less power than those closer to the root, so I'd expect that complaint to be filed away an no-op'ed on.

There's two different ways to indicate how fast a function, F(x), is growing.

One is to look at host much its value changes as x goes to x+d, and divide that to d to get an average rate of change from x to x+d. Take the limit as d -> 0 to get the instantaneous rate of change at x.

That gives a rate of change of Limit as d->0 of (F(x+d) - F(x)) / d, which is pretty much the textbook definition of d/dx F(x).

The other way is to look not at the actual value of the change but rather how much of a fraction of F(x) it was. That gives this measure: ((F(x+d)/F(x) - 1) / d. The instantaneous value would be the limit as d -> 0. That limit is of the form 0/0, but using L'Hôpital's rule we can turn it into (using the notation F'(...) for d/dx (F...)) the limit as d -> 0 of F'(x+d) / F(x) which is F'(x) / F(x).

When people talk of growth rate they usually mean this second measure. The first is usually called the rate of change. BTW, note that rate of change and growth rate are related. The growth rate is the rate of change of log(F(x)).

Exponential functions have an exponential rate of change but a constant growth rate. It is that constant growth that makes the concept of a half-life work for things that exponentially decay.
The reason is because the ARM `brk #0x1` instruction doesn't set the exception return address to the next instruction, so the debugger will just return to the breakpoint when it tries to resume, instead of running the next instruction. Recent versions of LLDB will recognize `brk #0xf000` and automatically step over it when returning, but I don't think GDB does this. With GDB you would have to run something manually like `jump *($pc + 4)` to resume at the next instruction. Clang's `__builtin_debugtrap()` will generate `brk #0xf000` automatically.

In America, today, Black culture IS culture and communism isn't viewed critically for the murderously-bad idea that it is.

Most of the immigrants that fled here from communism are either old, boring or dead. Kids today rarely have the benefit of speaking to older folks who fled Cuba, Laos, Cambodia, Burma, the USSR and others.

Instead they're following influencers on Twitch and Youtube who have extremely privileged lives speaking from ignorance about communism with no pushback.

What a loss for the world of music. My mom introduced me to his work through “WTWP: Wall to Wall Pachelbel”, an album that would become a staple on roadtrips. It takes a really gifted mind to make musical jokes, and Professor Pete was uniquely qualified to do so. He will be missed, despite living on through his music. May his memory be for a blessing.
I'd guess a lot of people would have their own special stories to tell.

However, do not underestimate the fact that some of these stories might not be easily disclosed.

A "friend of mine", let's call it Bob, decided to leave one of the big tech companies (call it "A"), and join another big tech company (call it "B"), which offers him exactly double the salary.

Due to a very unlucky combination, a former colleague at A gives the 30-day notice, then announces it on Twitter, and then speaks with Bob, who tells him that he's just joined company B, but another company has a perfect job for his. He applies, gets his job, and tells people that Bob gave him a hand.

Company A, as nasty as these big tech firm can be, decides that Bob needs to "receive a lesson" to avoid further "bleeding", or loss of other talent. See, my friend Bob was evidently quite popular when he was at A. So, A threatens to sue Bob, and company B, for breach of whatever.

The next three months are extremely painful for Bob, who has to go through a third party security audit and let them go through all his files, emails, etc, to then end the process with a mutual agremeent in which B pays the costs of the audit, and all is clear and done. AAaaand, Bob is never to disclose anything about this, publicly, ever.

I can tell you that Bob would love to tell this story, but alas, that's life.

Back to me: I had corporate jobs for 12+ years in different countries, most notably the US, and now I run my own firm (a VC based in Venice, Italy, called Rialto). I'm so happy I don't have to deal with this kind of crap anymore.

I wish all the Bobs in the world the same joy and freedom.
The biggest problem with Vroom (and its peers) from a business perspective is that they’re trying to operate a two-sided marketplace with incredibly low margins. On the sell side they’re competing with Carmax and co., which means they’re trying to win the most price sensitive customers which will inevitably lead to the smallest margins. On the buy side they’re trying to offer a better experience than dealers which means lower profits at similar prices. Add to this that the economies of scale don’t really help for used car dealers, and you’ve got a business that’s primed to fail.
Interesting. Lotharius encounter with Palmisano shows him as a mafia guy and not just a 'hustler'.

Sure, that would fix the bug immediately in front of you, but what if the same bug exists in several of the other copies of the dependency? Are you going to be able to track all of the occurrences down? I think that's the big tradeoff.
As someone who hasn't done more than dabble in Nix one weekend a few years ago, I don't doubt how powerful it is, but I'm not fully convinced that similar power couldn't be achieved with a better UX. My sense is that most people who voice concerns like the parent comment probably feel the same; right now, the amount of "activation energy" needed to get to the point where it's worth it feels too high, and I don't know if it's more likely that Nix will fix that (either in terms of better UX or documentation) or if someone else will come up with something that managed to give a better tradeoff in terms of amount of work needed to get started.
> I weep for the juniors that will be absolutely crushed by this garbage.

This is the real danger of this sort of thing. When your Copilot or whatever are good enough that they replace what is vastly superior for purely economic reasons.

I wrote about this trend applied to the unfortunately inevitable doom of the voice acting industry in favour of text-to-speech models a couple of months ago, using my favourite examples of typesetting, book binding and music engraving: https://news.ycombinator.com/item?id=38491203.

But when it’s development itself that gets hollowed out like this, I’m not sure what the end state is, because it’s the developers who led past instances of supplanting. Some form of societal decline and fall doesn’t feel implausible. (That sentence really warrants expansion into multiple paragraphs, but I’m not going to. It’s a big topic.)
Ambiguities stump people all the time too. That's why I insist on calling people rather than texting if there's something important I'm attempting to discuss. I don't have the time or emotional energy to attempt to figure out someone's actual mood when discussing something via text.
Just out, but from a quick look, it is surprising that AI received such a minor role in the contributions.
> I feel gross about fluffing it up, instead focusing on outcomes and facts

Sounds about right to me. Outcomes and facts should be enough.

Maybe you're focusing a bit too much on autism. If you appear personable (and apparently you do based on the feedback) you're already more than half way there.

I would say, maybe you present your achievements was a "detached" demeanor? Maybe you don't sound proud, excited or passionate enough when recounting facts and outcomes? I'm kind of shooting from the hip I guess, but it's obviously hard to tell if there is a problem or just bad luck.

I cant help but recall a 2015 Peter Theil interview with Tyler Cowen [1] where he talked about the black magic predictive power of company names. Hard to unsee a company called "ever bigger" getting overextended.

Ugh spot on. I actually quite enjoyed the work I was doing at the Big Cos and Unicorns, and wouldn't mind doing it to this day. However, the culture that performance management wrought was so awful, it makes me not want to work in tech at all. The incentives they create are so perverse, it's sad how much they crush otherwise fun and innovative environments.

I’ve not heard much of his music (I must remedy that), but I remember hearing one of his pieces (perhaps on Prairie Home Companion?) which was an operatic setting of a joke (“transporting gulls across a staid lion for immortal porpoises”) and it elucidated so much of how opera worked structurally that I never got from listening to actual operas. There’s a lot of education hidden in the jokes.
This is not about about some microbe conservation effort. The whole idea is to preserve the conditions in which life can be discovered, and if it is, studied. Think about how much harder it would be to detect Mars life if organic molecules from Earth are present in quantity, let alone the interaction that could occur.
I think it's a sign of how far HN has strayed from its mid 2000's roots.

This was a great walk down the memory lane for me: I was a research intern at IBM Almaden in the summer of 2000 (crash learning C++ from Horton's Beginning Visual C++, I was a Unix/C person) and shopped at Fry's in Sunnyvale. We used to have lunch with interns from HP and other companies and visited Xerox PARC, it was like visiting Shangri La!

When I first visited the US in 1992 I visited the Silicon Graphics buildings where the person who hosted me worked, it felt infinitely innovative. In 2000 they (now SGI) had built these cool buildings (which is now the Google campus) and offered free dinner for employees and families on Tuesday evenings. You don't get to hear about them much.

In 1993 we had a brand new Silicon Graphics Indy (https://en.wikipedia.org/wiki/SGI_Indy) in our lab and loved it, so different from the beige boxes. Somebody ripped the first three songs from the Eurythmics Greatest Hits CD and had them playing on a loop into late nights when we were working on our Wavelets course projects (we had Daubechies's Ten Lectures on Wavelets as the textbook).

Good times!
I was at Microsoft from 1991 to 2007, almost always as an IC, and don't ever recall stack-ranking teammates. That was always something done by the managers, not the ICs.

> If we find evidence of current/past life on Mars, what is the math that this means there's "overflowing" life throughout the universe?

If life on Mars is related to life on Earth, that doesn't tell us very much.

If it's not related to life on Earth, then that means life can arise easily, so we should expect to find a lot more examples. Currently any instance of life is guaranteed to find at least 1 example (itself), so moving from 1 to 2 is significant.

> If there is no evidence on Mars, what does this show whether there is no current/former life outside the inner solar system

Evidence for the "Earth is special" hypothesis gets stronger the harder we look and find nothing, but we can never know for sure. At this point, we've hardly looked anywhere.

That's mostly not true.
Polling has never implied blocking. It’s actually a way to avoid blocking. I think you’re thinking of “busy-wait loops”.

The difference between “polling” and “busy wait” is whether or not the CPU is doing other unrelated things between samples.

The difference between polling and interrupts is that with interrupts the CPU can halt entirely while waiting rather than having to take those samples in the first place.
I have been wondering how to support interactive / real-time web apps based on Snowflake data. I suppose pushing down to DuckDB a subset of data needed for a chart would be one way to do this...
Offhand, things that used to just be "AI": Expert systems, markov chains, genetic algorithms, data mining, and identification/classification.

People in the field would probably say they fall under the AI umbrella, but it's not the common viewpoint. Either someone can conceptualize how they'd work (expert systems) or they've been watered down and turned commonplace (markov chains in software keyboards, identification in Facebook images), and either way it disassociates the technology with the "intelligence" part of "artificial intelligence", so is no longer thought of as part of it.
