Hello HackerNews! Author here :)

TL;DR: We devise a linear SDE/ODE model to imitate per-class feature (thinking logits) dynamics of neural nets training based on local elasticity (LE) [1]. We found the emergence of LE implies linear separation of features from different classes as training progresses.

The drift matrix of our model has a relatively simple structure; with that estimated, we can simulate the SDE using the forward Euler method, whose results align reasonably well with genuine dynamics.

Local elasticity models the phenomenon observed in DNN training: the effect due to training on a sample is greater for samples from the same class, and smaller for samples from different classes. For example, training an image of cats facilitates the model better learns images of other cats while not so for images of, say, dogs.

Any comments/thoughts/questions are most welcome!

You misunderstand Spinoza. Spinoza is a [1] Panpsychists. Spinoza's logical arguments in Ethics won me over to this perspective.

"The more resources people have, the fewer children they tend to have in fact."

I dispute this, most people want to own a home and be able to provide for their children, and average age of first-time homebuyer in UK has risen to 33
> Also, not particles, but fields, actually.

Why are there fields?

It's turtles all the way down, and it fundamentally comes down to "why something rather than nothing"?

Nothing has no potential to create anything because it's literally nothing. It can not have potential.

So where do these crazy forces, fields, the quantum observer effect come from, out of nothing?

We will never find an answer to that question because it is literally unanswerable.
Not to mention, carbon capture these days is mostly about capturing emissions at source, not about distilling CO2 out of the atmosphere at large. It doesn't work very well, either.

Extracting CO2 from the atmosphere will be energy-intensive and inefficient. Where are we going to get all this spare energy to scrape back the disastrous consequences of releasing a well-mixing destructive greenhouse gas? Uh, solar panels? Nuclear? A trillion trees? Spending energy on such CO2 extraction will literally have no economic value. And we're going to fund that how?
Same here. I still think the tiles interface with vertical scroll was the best one for phones. I don’t dislike either Android or iPhone, but I still miss my Windows phone.
The Moderna vaccine was designed on January ~12 2020. All problems since have been social rather than technical. And if Balaji Srinivasan was head of the FDA we'd all have been vaccinated by December last year.
> Taxes are higher in Europe, which disincentivizes risk taking and ambitious individuals.

The implication is unproven.

Furthermore, most FAANGs dodge most taxes and have offices everywhere including in Europe, making your point moot.

> Labor productivity is also lower in Europe.

That has to do with US geopolitical influence. (and army).

> Finally, Europe still has a culture where software engineers, cloud architects/products/managers/etc. are viewed as code monkeys and the people who really matter in a corporation are the finance people and upper level executives.

That depends on the company. Again, there are european companies in US and US companies in EU... and yet the salaries are in no way aligned.

> Europe also suffers from a brain drain to the US (and Canada to a smaller proportion). Many of Europe's best and brightest software engineers have already emigrated to the US, leaving behind the less productive ones.

Analysis on most technical or important FOSS projects prove otherwise, with EU having the brightest.
> It's not so difficult to filter out good programming languages from poor ones

I beg to differ. There are some pretty awful but popular programming languages! No, I won't name them because I don't want to ignite a flame war here.

It's actually not easy to do a good programming language design. It looks obvious only after the fact.

> And lastly bad amateurish programming languages can be ignored. They have little consequence on the whole of society.

They impose a lot of cost on society, both direct and indirect.
Not near the top, no, but according to the numbers it is median. I'm sure there are larger salaries out there but this article makes it sound like it is normal. Which in a roundabout way was my point.
You're correct so I'll explain what I was trying to get at.

At the moment, focusing on dwindling birth rates is nonsensical because the world population is projected to be 10B people by 2050. So the issue isn't lack of people, it's the inability of various nations to properly coordinate a response to an existential crisis (global warming and increasing volume of CO2 in the atmosphere: https://climate.nasa.gov/climate_resources/24/graphic-the-re...). Dwindling birth rates in Britain should be the last thing anyone is worried about if their real concern is not having enough people in the future. I mean if they're really concerned about lack of Brits then I guess it makes sense, but globally, on a planetary scale, worrying about local birth rates is not really something to be concerned about.
Because with a trivially large enough network of friends willing to game the system, you could just keep buying each other top-paying jobs over the course of a few years. So long as you're at least a mediocre engineer, you can make it past the two-month mark and everyone gets their ROI.

> people with the ability to afford payment have a higher chance of being hired

That's the other very valid reason that this idea sucks. People from disadvantaged communities now not only have the existing hurdles to face in entering the tech world; now trust fund kids with rich friends can continually skip the line and buy the jobs that others are applying for. And a company is going to take the pay-to-play candidate, because it's easier than running an interview process.
To some extend, yes. On the other hand, they’re currently the only service where I can set up one VM, give it my AWS credentials, and have fully automated scaling.

The hoops you have to jump through in Github are absolutely unfun.
Serious question: How did they even find you? Did they seriously do a dragnet of all birth certificates and send you a letter in Canada or something?
That's kind of how it already works with recommendation letters. The result of nobody wanting to say no is that every letter is positive but the number of adverbs chained together signals their true opinion of the candidate rather than the number of dollars.
It's experimental medication, with no proven track record. The media and big tech platforms have been censoring the medical community. Most people under 50 are not at high risk from COVID and the reports of adverse reactions to the vaccines are legion. The people advocating for mandates are themselves offensive and I think history will prove them to be utter monsters.
That's definitely part of the problem.
That certainly puts an interesting spin on the one time I had to ride the back of a bus from west coast to east coast. It was three days and I was physically and mentally exhausted at the end despite sleeping for a fair chunk of it.

Edit to add: Thanks for your input on this, it's insightful and interesting!
Perhaps because vegetarians always need to explain themselves to friends and found it frustrating?
I wonder to what extend plastic packaging and the ubiquity of low quality food often found inside is contributing to obesity related illness.
Apple was derided when they started opening stores. Gateway had tried it and it killed the company. Dell tried it, but we’re killing it with the computers-by-mail business and it’s opportunities for financial engineering.

What did apple bring to the game? With a tired product line in a maturing market, the last thing they needed was another expensive effort in a domain they had no experience in (retail) while simultaneously killing their retail channel.

It’s my understanding that the popular understanding turned out not to be completely accurate.
valve is very differently structured and has had a very tough time pivoting to hardware. We can see this obviously with steam machines where they just didn't want to get involved. Then the steam controller, steam link, and now steam deck...

they're getting there but they're not exactly there yet. I think oculus taking their research tech and turning it into a $2b acquisition and a threat to steam because of its closed garden was a big wake up call.

We'll see how they do in the future I guess.
Releasing RCVS-hack, the tool used in the Missouri breach
One reason discussing those numbers is hard is the variable compensation section: RSUs.

An E4/L4 (the level right below senior) easily makes 400k right now depending on which company they joined. Their typical offer was 160k base and let's day 82k RSU (325k over 4y).

With the usual (~15% of base) bonus, that's 160 * 1.15+82=266.

But now let's assume they joined 2 years ago, so they got refresher of stocks that are roughly 20k per year extra (80k vesting over 4y), 266+20+20=306k.

Here's the catch though, the 82k/y from the in-hire grant are now worth 160k/y: it's {stock price today} * 1/4 * 325k / {stock price at join date} , and look at FB, GOOG, AMZN etc trajectories.

Same for the refresher, the oldest one is probably worth around 40k/y, and most recent one probably worth 30k/y,

So this year exact TC could be (bumping base with 2 usual raises to 170):
170 * 1.15+160+40+30 = 425k.

That's ignoring extra (~10% of base) for on-call compensation.

That E4 doesn't need promo to E5. The math can be repeated for E3 or E5, the higher the stock number was, the higher the effect.

That's the effect of stock compensation and alignment of employee compensation with company performance. Of course if those share prices go down, so does the TC. There's a company in FAANG known for their frugality famous for not offering refresh "because the stock price is doing so well", but even without the refresher, someone's initial stock award from 2-3 years ago is worth a lot more today.

Some companies are starting bad trend these days due to them offering only 1 year vesting stock awards, instead of typical 4 years (smaller on-hire awards but bigger refresh), where an employee cannot benefit from the compounding effect of stock growth anymore. The employee can "hodl" their vested shares, but the vested shares are usually less, since ~1/3 is removed to pay for the tax the vesting represented.
So, your argument is that methaphysics is based on belief and no logic? :)

TBF, all of those can be expressed into binary code and mathematical formulas and mathematical logic, however there does not exist proof that there exist God.

Science requires proving that something exist - not disproving that something that is made up centuries ago does not exist!

I am Uruguayan and have never even visited the Bay Area. But just cry "tech bro" and move on.

>We have the tech to build super cheap housing for everyone, yet poverty and homelessness skyrocket

This is a great example of a regulatory (rather than technical) issue. Global cities should simply be built up into the stratosphere by decriminalizing construction, anything else is a policy failure.

Similarly, climate is solved by decriminalizing nuclear power.
Please read Spinoza Ethics. There seems to be much misunderstanding of Spinoza Philosophy going on in here. Which isn't unlike how he was misunderstood during his time.

That's an incorrect understanding of rainforests, and has me scratching my head at the article.

It rains because of Hadley cells. Hadley cells don't disappear with global warming, so it will still rain a lot in the tropics. Why on Earth would it be "barren?" A few degrees of temperature doesn't matter to plants: as long as there is sunlight and tons of water, they should be fine.

Now if Hadley cells widen or shift northward, that could be a problem for the US. But no matter what happens, Hadley cells still have to rise near the equator.
The resource that is most valuable for us on Earth is not oil or water or gold or rare earth metals.

It is the human brain and human potential. I would argue that we have developed this more than we ever have before in human history. We have access to more knowledge than we ever have had before. We can communicate more than we have ever had before. More children get good nutrition and so can develop normally than we ever have before. Women, especially, with the advent of safe, reliable birth control, as well as low infant and maternal mortality are encouraged by society to develop intellectually more than they ever have before.

If you look at the past, it was said that humans would exponentially grow in population. Turns out birth control and female education and empowerment radically altered that trajectory and we will actually have a stable population soon. People were predicting wide spread famine, but the green agricultural revolution enabled us to produce more food than we have ever been able to.

The most important thing is not to be consumed by doom and gloom but rather embrace that human potential is our most powerful resource and seek that every human on earth will be given the resources and opportunity to fully develop into all that they can be.
There is no such thing as natural evil. The Inverse of love is fear. Whether something is good or evil has more to do with the social constructs of the times than any morality. That said, a morality based on Truth, Freedom, and Love is cooperative as above and below. The unfalsifiable god is the Truth god.
It's close enough to 0 to be a rounding error. Even some of the recent unicorn IPOs didn't return enough for employees to offset what they could have made working at FAANG.

>Full frame sensors have thin depth of field.

...when they have a large aperture. Stoping down the lens will widen the DoF on that full frame sensor

you don't have to. only if that is the style you are wanting to achieve. you can also stop down the aperture. it's not as obvious as non-macro, but still something doable.
I think concepts like Spinoza's or Deism or people who declare themselves "not religious but spiritual" are just having trouble parting with the comfort of religion even though they know there's nothing there.
That’s it for me. I thought HN was a place of intelligent people and all. But here we have it, someone supporting a literal scam!
I think I was pretty clear in my comment above in saying that I support right to repair and the ability to modify, disassemble, and interrogate the device you have in your possession.

I appreciate that folks in this thread are attempting to propose legislation to stave off behavior they believe is dangerous. My concern is that using legislation in this way has knock on effects that make free society radically worse, because at its core it requires being OK with using government to restrict what technology combinations are legal to bring to market.
In The Olde Days you could schedule a return; when the fedex driver stopped by you could ask them to wait and pop your laptop into the box and hand it back, and have the repaired machine the next day. No more.

Or are you pointing out that social security, despite supposedly being a fund that I pay into to fund my retirement, is actually just a giant pyramid scheme.

And if you know its a giant ponzi scheme, then you are on the side of "everyone keep fucking to keep the ponzi rolling".

When the oil runs out, and the phosphate is gone, just remember that a few billion more kids and we'll be fine, right? Just keep fucking.
Cryptocurrency can obviously work, but bitcoin is not realistically going to be widely useful.

For the last three months it has had a throughput of 195 bytes per second.

https://bitinfocharts.com/comparison/size-btc.html#3m

There is no universe where the fact that everyone in the world will get about three transactions on the main chain for their entire life will give people the dream of sending money to each other directly electronically. If you start using apps and side chains for everything you are back to centralization and aren't much better off than venmo.

This is why during heavy use single transactions cost more than the hard drive space needed to store the entire chain. It just doesn't make sense to think the entire world can run on 700KB every 10 minutes. Every other decentralized cryptocurrency is more viable.
> Yeah individual voter fraud, per all the vote security experts, basically isn't a thing

While I would allow the possibility of it being a real issue, that’s not really what I meant. I’m most surprised that TFA claims that strict voter ID requirements have no impact on perceived fraud.
Honestly, I think it deserves the outrage. It's one of those ideas that just needs to get shot down as fast as possible.
Its not just privacy. Corporate exclusivity power also hurts competition, which in the long run is worse for everyone. (Well, except maybe the monopolist).

For example, when AT&T owned all the telecoms equipment in the US, other companies couldn't make new products using their system (like answering machines or modems). Having anyone able to design, connect, use and sell new devices on top of their infrastructure is an incredibly important feature.

And facebook knows that. They launched facebook on the internet (which is an open platform). Facebook couldn't have been created in the first place if not for that.

Facebook owes its existence to open platforms. Lets not allow the train of innovation to stop here.
Could you try to find words? There’s so much outage but not a lot of cogent criticism.
Sounds like the mafia.
I would say countries that prohibit dual citizenship are much more punitive towards those who leave. In the case of the US, compared to say Western Europe, we are so much more inward looking that policy towards expats is mostly one of neglect to even consider their interests.
I lived in a state that made it insanely difficult to register to vote, but easy to vote. Registration required two forms of ID, one with your picture, both with address.

A while ago, the state changed the rules so that one form of ID was required to register (photo required) and one form of ID required to vote (photo required).

This made registering much, much easier, which made voting much much easier, especially for young people.

There was national freak out over this. HOLY FUCKING SHIT THE REPUBLICANS ARE REQUIRING IDS TO VOTE! YOUNG PEOPLE AND MINORITIES WONT BE ABLE TO VOTE!

Voting rates went up, especially among the young. The only people who had problems were very elderly people who had lived at the same address for long time (no need to register) and we’re had stopped driving. Most were Republican.

Partisan organizations released non-peer reviewed studies showing the vote was superseded. Partisan publications (for example, Mother Jones) treated these press releases as fact, but mainstream fact checkers pointed out they were bullshit. They have since been largely scrubbed from the Internet.

I can’t imagine why it’s OK to require two forms of ID to register (a consensus position as of 2007 or so), but requiring a single ID to register and vote is a human rights violation.
I haven’t seen any well articulated arguments about why this is so evil. I think it’s not likely to succeed because it’s a complicated 3-party transaction but I can’t understand why it’s evil.

Can we have 100 billion mega-yachts sailing around? 100 billion private jets, billions of sprawling opulent mansions in each of the most desirable and expensive cities? 100 billion private rocket ships and 100 billion vacation houses on Mars?

The impact to other life on earth would just be horrific too. It's already way beyond the point of sustainability. Even if you just magic away the footprint of all primary production and all manufacturing, just having that many people living, producing waste, impacting habitat is my idea of a nightmare.

I hope population naturally gradually subsides to some actually sustainable fraction of the current that does not rely on heroics like fusion, asteroid mining, and scrubbing industrial chemicals from the environment. Tens of millions of people, perhaps.
Why should the Internet be accessible only to people who have undergone a high school curriculum that teaches it? That already excludes a large portion of the population.
> in mere centuries.

I'll just add to my own comment that 3% economic growth for 480 years would mean the economy in 2500 would be 1,500,000 times its current size today and in the year 3000 almost 3.8 trillion times its current size. So obviously, exponential growth is going to come to an end, probably slowing down this century and we will absolutely have to reach sustainability on Earth.
I don't think 4-5 years experience is Sr level, as used in the Robin example. $100k with 1% of the company seems... OK? The salary is a mid level software engineer is closer to $150k, Chicago should down adjust a bit, so maybe $130k salary in big tech. Realistically, you are looking at $162.5k with bonuses and stock. How much is the startup worth now? She's probably passed on (very roughly) $300k of comp, so if that startup valuation is sitting above $30M she might be close to even and if it provides an exit above $100M she'll have done well. If not, well it was a lottery ticket.

As for the other person, Staff+ does not necessarily translate between companies, and especially does not translate from companies in very different cultures to the big tech space. It's not impossible, but just because someone got the title of Staff engineer in one market does not mean they will be able to get that title in another market.
