> not reducible to mechanical models [...] is much more true for quantum mechanics

Yes, but... a caveat.

How big is an atom? "Unimaginably small" is an oft repeated phrase. What is an atom? "Definitions [...] models [...] skill at switching between models". Electron behavior? Quantum... "unintuitive... the equation is understanding".

So how well is "small" taught? Horribly, even by the lackluster baseline of current science education research. Asking first-tier medical school graduate students how big cells are, is not happy thing. But hey, maybe cells are "unimaginable" too.

So how well are atoms taught? One challenge in teaching high-school stoichiometry, is students not thinking of atoms as real, as physical objects. But hey, maybe that's a failure to "switch models".

So how well is electron behavior taught? Well, when students use the many realistic interactives emphasizing molecular electron density... oh wait. Well, when students view the many molecular dynamics videos showing electron density... oh wait. They do exist... now find them without using google scholar and sending people email. :/ But hey, if students ever do see them some year, maybe no understanding will result, given how unintuitive it all is.

Punchline? Teaching things badly seems associated with failure attribution errors. As with education research that's "we taught atoms really badly... surprisingly that didn't work... so we draw the obvious conclusion... students of this age aren't developmentally able to understand atoms".

And physics side... there often seems a blurred vision of objectives and their properties. There are a great many plausible learning objectives between "atoms are real" and "i∂_{t}ψ=Hψ". And the usefulness of "mechanical" models varies greatly among them. So "the equation is understanding" gets repeated, in contexts where it's inappropriate, and where it distracts from a broad long-term societal failure to improve wretched science education content.
I think this starts to get at it, but missed the lopsided situation we're in today.

In the small town he mentions, yes, there's little privacy, but it's constrained to the small town, and largely equal. Everyone knows about everyone.

If someone from outside showed up to ask questions the town would likely protect your privacy, but also let you know someone was asking questions.

Instead today there are corporations (some public, some very secretive) gathering vast amounts of information and it's impossible to know who knows what about you. That information is also much more easily tradable, so it spreads.

For example, in the small town, pre-IT, it was hard to produce consolidated, and deep reporting of who's buying what, beyond the memory of the staff.

Now Target, Amazon, etc can know not just what you're buying, but what you're looking at, and correlate it with information from other sources, and it can be easily correlated with public records, and other information on a scale that's just wasn't ever possible historically.
DocuSign is valid by statute: https://en.wikipedia.org/wiki/Electronic_Signatures_in_Globa...

Their security implementation or the authenticity mechanism they have for recording is not even really up for scrutiny, so long as they can provide some kind of proof that the signing occurred and that the counterparty signed with an understanding that the electronic signature was the same as a real signature.
Yes, that is one definition. There are others.
I guess I just don't value "contact discovery" as a feature?

I just don't see it as a casual thing the way the target users of these apps apparently do.

I want to explicitly control, per any form of communication, each person who is to be made to know that I operate that form of communication and whether or not that form of communication with me is open to them.

I do not want to open up a new app and have a large populated list of past acquaintances appear, I absolutely do not want to appear in such a list, I would rather not use a given app than risk having someone show up messaging me uninvited.
Somewhere I have a printout (green ruled 132-column line printer of course) of the SYS$SYSTEM:SYSUAF.DAT file showing my account with all 32 privilege bits set (including of course: "change mode to kernel"). This after spending the weekend writing a perfect VT-100 "trojan" that I left running on an operator terminal with some social engineering, grabbing the system user password which I then used to escalate my account's privileges.

Coincidentally, a few minutes later, the 780 threw a fatal memory error and shut down. My 17 year old self assumed he had broken the VAX, returning to work (I was an intern) on Monday morning expecting to be fired.

Writing the trojan, which had to correctly implement all the terminal timeouts, responses to ctl-y and so on, was quite a challenge. Required me to understand $QIO, by reading the microfiche copy of the terminal handler BLISS-32 source code.
I know it can happen to anyone and that every system will eventually go down no matter how many resources are spent or how smart you are. Heck, it might even be financially prudent to not chase those last 9s of uptime.

But r̶e̶l̶e̶a̶s̶i̶n̶g̶ posting this hours after a huge outage that affected most services for over an hour and also less than 12 days after a similar multi-hour outage seems somewhat ironic.

EDIT: guess I hurt someone’s feelings.

You can also send two streams (high and low quality) from each client and make other clients request the right one from the server. Yes, it's slightly more bandwidth than before and now complexity. No, it doesn't require full mesh of connections to be E2E.
Roku gets paid by Netflix and some other OTT providers, but it's nowhere near enough money to turn a profit. They need to sell ads to come anywhere close to making money. Their edge is that their software runs on really cheap HW, but it still costs money to manufacture and distribute. They probably lose a little money on every player they sell and make it back with ad deals and licensing agreements.

Excerpt:

"Dealing with fake news will need to involve more than simply adding a piece of code in today’s tech, and could require a lot of societal transformation.

The fear of giving everyone a voice

It is not the first-time disinformation is threatening civilizations.

Christianity faced the same crisis when the Bible was translated from Latin to other languages which any person could read and understand.

The church had resisted the move in the fear that giving everybody a Bible would result in skewed interpretations and rise of cults that would crop up everywhere.

That is exactly what happened.

[Side thoughts: Is the Tower Of Babel - A Metaphor For This?]

Today, cults after cult seem to spread all over the world with the educated being equally prone to the disinformation as the non-educated. It is like half of Christianity today is fake news."

Disclaimer: I'm not saying I agree with this assessment, nor disagree, but you have to admit:

Saw this thread -- thanks for sharing again! Here's some more context:

I'm Mike, co-founder at Zapier and head of Zapier Labs. Today our Labs team is launching a public version of Zappy: a fast, free screen capture tool that we built for our remote team. At Zapier, we have 300+ teammates working from across the globe with no central office—we've been fully remote since day one. We've learned that increasing communication bandwidth is crucial when you're working remotely.

I wanted a tool for screenshots/GIFs to supplement apps like Slack, but nothing on the market had the mix of speed and features we were looking for. So, built it internally. Zappy is a cornerstone of how we work at Zapier, nearly everyone at Zapier uses Zappy every week (voluntarily)! And we want to share it.

Why share now? People around the world just experienced a sudden shift to remote work—and we know life sans-office comes with unique challenges. We want to share our experience and make that transition a little easier.

Our goal with Zappy was to provide a screen capture experience that was so fast, people would actually want to use it to communicate. To capture something, you hit a keyboard shortcut, draw a square, and press enter. Zappy copies the image to your clipboard so you can paste it anywhere (or provides a path to your GIF/video).

You can draw annotations, record a selfie view, and stitch shots together. Captures support image, GIF, and MP4 formats. One of my favorite features is being able to grab past captures from the Mac menu bar, instead of digging through folders.

We're working on more features, too, like self-hosted captures on S3, sharing permissions, and a Zapier integration. :-)

Zappy is free to download and use for anyone (you'll need a free Zapier account to log in once). And, for paid Zapier customers, you'll get free capture hosting while it's in early access.

I'd love to hear your feedback and ideas. I hope you find Zappy useful!
What about Trax (https://github.com/google/trax) and how does it compare with Flax or Haiku?

Interesting that googlers who are supposed to use Tensorflow are now actively developing a new autograd engine and at least three new DL frameworks on top of it. What do you think about this segmentation?
It's not testing the recruiter. It's trying to get information about how the company works. That's exactly the sort of question I'd expect a recruiter to be able to answer, at some level. I would gladly accept "I don't have a really good answer for you, but I can set you up to talk to someone who does." If they don't have an answer better than the NYT, and they're willing to do that, I'd be satisfied with the recruiter on that point.

As far as being ready to talk about the role, asking these questions is talking about the role, so I don't understand what you're getting at here.
It looks to me like they've still won the lottery.
Newton's laws are essentially 1 law and all can be inferred from just the 2nd: f = ma. So, I think your point is stronger than you've written.

Also, Newton's laws and Maxwell's "laws"/equations are laws in different senses. The latter is far more specific to the causes of a force and also holds stronger under relativity, by the dual nature of electromagnetism. Whereas the former is often on the left hand side of equations involving the latter and, as we know, is completely up the left under relativity.

Hence, comparing these as succinct yet fundamental laws of nature is doesn't really compute. That is, unless you want to go down the inertial/gravitational mass rabbit hole.

I'm wondering if this has floated to the top of HN because of the recent GCP outages (both a few days ago and from this morning). I'm trying to figure out if this is coincidental or ironic.

NOTE: As a heavy user of GCP we we're affected by the three most recent outages (GCIC20005, GCIC20004, GCIC20003), but I definitely feel for those that were impacted.
I'm pretty sure they were getting paid for Netflix signups from the beginning.
True in many other European languages too. Spanish, Italian, Portuguese come to mind.

In English we derive it from Saturn, which is also a god, but I guess too far removed for us to think about it. AFAIK a fair number of European names for days are derived from pagan gods. Even more if you count the Sun and Moon (Sunday, Monday) as gods, as many historical European cultures would have.

Even Thursday is for Thor, Friday for Freya. Which is to say Germanic gods too, not just Greco-Roman or Hebrew.
They've done sampled serological tests in at least one town in Italy. If you compare that against excess deaths in March, you get an Infection Fatality Rate of 2%.

Perhaps it will be better in the U.S. due to age structure, but perhaps it will be worse due to the high prevalence of obesity and diabetes.

Either way, California won't have reached herd immunity until approximately 600,000 people are dead, barring some therapeutic breakthrough.

Your comment is based on a summary quote, the full text linked in the article makes it perfectly clear:

> 57 percent are less likely to interview a candidate they can't find online

> 54 percent have decided not to hire a candidate based on their social media profiles

> Half of employers check current employees' social media profiles, over a third have reprimanded or fired an employee for inappropriate content

> 70 percent of employers use social media to screen candidates, up from 11 percent in 2006

For more than half of the world's population or 80+% of all internet users "an online presence" means precisely "social media". Nothing else comes even close to that. It's also one of the few segments where people use their real identity. Your anonymous HN account will fly under the radar.

Let's not bury our heads in the sand, employers will check social media so they don't hire anyone who's publicly offensive or extremist, unprofessional, trashes their employer, even someone posting too much or with poor communication skills, etc. From a link in the article I posted above [0].

I have problems with most tech companies on some level (Microsoft includes too much telemetry, Apple is monopolistic on the app store, Google owns half the internet, Netflix's autoplay is an anti-pattern). Amazon's feels like "company treats lower-wage workers poorly", which is true of every company I know of except Apple.
I understand and mostly agree with your concern about the censorship of messages these outlets disagree with. I must point out that while unethical, it is not a freedom of speech issue. The constitutional right to freedom of speech is in relationship to the government only. If Medium and other platforms were a government run then you would be correct. Thankfully, they are not. Pressure put on the censoring by platforms by you and I is the only way to change their mode of operation.
Please don't break the site guidelines by posting insinuations of astroturfing. Overwhelmingly, such perceptions are simply in the eye of the beholder. I say that based on many years of looking at that data, and you can find more explanations here than anyone would ever want to read: https://hn.algolia.com/?sort=byDate&dateRange=all&type=comme....

If you're worried about this kind of thing, follow the site guidelines and email hn@ycombinator.com so we can look into it. (We always do.) In this case, though, the simplest explanation seems adequate: the community is divided. When there's a popular divisive topic, people who feel strongly for side A always feel like the amount of support for opposing side B is 'eerie', because it's hard to imagine how it could possibly be in good faith. Of course B feels the same way about A.

Edit: oh dear. It seems like you've been using HN mostly for nationalistic battle lately. We ban accounts that do that, so please stop. It's emphatically not what this site is for, regardless of which nations are at issue.
Well, maybe that's what he's trying to get across, but it seems largely irrelevant to the interviewer's question. He could just have given a physics textbook level explanation of how magnets work. I'm not convinced that there's some kind of profound misunderstanding evident in the interviewer's question that needs addressing in long and rambling terms.

A downside they don't discuss in the article is that there's less slack in the system. If you're already running your machines constantly, and something goes wrong (ex: war, pandemic, famine) where you suddenly need to scale up, you were already right at the edge of what you could be doing.
> stopped shipping everything but essentials

Not true. They are still shipping non-essentials just with longer delivery times.

Now, objectively speaking, Amazon could have done far better in prevention when this started. Why is it that just recently they introduced temperature checks? That’s should have been a -day one- (pun intended) measure. They were doing that in China months ago.

Einstein Notation is similar in this regard. It makes the 'mechanics' of tensor mathematics much easier to deal with. Kinda like how arabic numerals are a lot easier to manipulate than roman numerals.

I'm not sure sure, but I believe that Helen Dukas, Einstein's secretary, is the one who came up with Einstein notation originally. She was just trying to get through his notes faster when writing things up and that method of notation later became accepted. I can't find that citation though, so calling it Dukas Notation is for the moment erroneous.
