Then you'll be eating small bits of PTFE (commonly referred to as Teflon), which is completely harmless and will pass through you unaltered.

PTFE is a fluoropolymer. It is a completely different substance than the chemicals we call PFAS. PFAS chemicals are sometimes used when applying PTFE to surfaces, particularly as surfactants, but all current manufacturing processes ensure that no residual PFAS is left behind in PTFE-bearing products. As far as I know, nobody has ever found residual PFAS in cookware, for example. In over 50 years of use in cookware, there is no evidence that PTFE-based nonstick coatings have any negative health effects whatsoever, as long as the cookware isn't overheated. PTFE is among the most stable and immortal of all organic materials, and is logically unable to interact chemically with biological systems. You can eat all the PTFE you want, and it will never show up in your blood stream. PTFE is widely used in medical devices that are implanted inside the body, where it's inertness makes it the ideal coating. It's as safe as any material can be.

Unfortunately, non-stick cookware is pretty easy to overheat, and when that happens it can release some pretty toxic stuff such as fluoroacetic acid. But this has nothing to do with the PFAS chemicals we're talking about here. There are actually very few reports of any real-life health effect from overheated nonstick cookware, and those we do have involve only temporary flu-like symptoms.

The real hazard of PTFE is not in its end use, but rather it's an environmental hazard from its production. It is safe to eat Teflon, but I would never want to live downstream from a production facility.

This is completely different from products that use PFAS chemicals. Prominent examples are outdoor clothing, stain resistant coatings for furniture and carpeting, firefighting foam, and many brands of ski wax. These products contain large amounts of PFAS, which can easily end up in your body. The effects aren't well known yet, but this may well be an global health and environmental catastrophe. But again, that has little to do with PTFE. Two different things in this regard.
illegal where? that's not the case anywhere in the US that I'm aware. Most any legislation about exists is limiting modification to environmental parts like catalytic converters.
Is that a common thing to do? sounds extremely bad mannered and unprofessional to me.

You take an offer, start working at a place, then two months later you go: "Welp, sorry guys, grass is greener on the other side, I'll be going now. It's not you, it's that you use Angular and they have React over there. Screw you and the effort you put into training and onboarding me for the past 8 weeks."

Am I out of touch or something?
ZFS does that, except with error correction codes applied against bitrot. All you gotta do is turn on a ZFS-system and hit the "scrub" command. That automatically checks all checksums: and error-corrects all data that fails a checksum.

If anything, ZFS makes that whole system you just described easier and more automatic. Its not really hard for me to push the "scrub" button on my Nas4Free box every few months.
And presumably, even with detached single family homes in more spread out cities, delivery people don't just drop a package on the sidewalk. I live in a fairly rural location and packages are mostly left in my mailbox or wherever against the house. But I assume in busier areas, delivery people actually make a minimal effort to not make packages completely obvious from the sidewalk.
My understanding is that it’s geographically limited due to depth issues.

They don't even need to do that. They can just lie to you. "Hey, your buddy just totally ratted you out in the other room, you better tell us your side of it if you don't want to take the rap for everything"
Good luck on walking the fine line between the creative and the perverse. You get it wrong and you introduce an actual negative into the group.

The best non-conformists are those who can conform, and demonstrate that in a productive way, but really prefer to crayon outside the lines. Those sorts maintain enough empathy with the rest of the team to be a good “team player”, and are then able to introduce new ideas into an environment of “let’s give it a go” instead of active hostility to the jerk.
Which do you think is more likely:

A) There was a bunch of money allocated to climate change. We then took the money away and used it to bring an asteroid rock sample back to Earth.

B) There was no money allocated to climate change, because there is huge resistance to allocating resources to solving climate change. Unrelatedly, we took some money from a variety of trivial purposes and used it to better understand our solar system.
Right, but you'd somehow need to not only get your hands on the URL of a private doc but then inexplicably convince them to use the "send feedback" feature on that same private doc. This is a neat bug, don't get me wrong, but I don't think this is even something most would consider exploitable. IMO this is equally exploitable as telling the victim to hit the button labeled "PrntScr" on their keyboard and then hit Control-V/
This is essentially what the book Bowling Alone is about. It's worth reading, along with the writer's other research.

This is not intuitive so Apple added 500ms to the visualization.
I agree. The penalty on the user of AI would in turn incentivize the user to penalize/reward the AI developer.
But I’m not sure if it’s reasonable to require every user to be able to assess the long run accuracy of a statistical system given their limited interaction. Maybe there’s a market for companies to reliably assess and certify AI systems or by creating a sort of a prediction market that penalize overconfident false positives.
Put another way: "Apple pays project leader Bay Area salary + pre-iPhone AAPL stock to support open source development for more than a decade." (There are certainly more projects Apple relies on that deserve this!)

Most of Apple's extinguished open source projects are ones they started themselves and then abandoned.
When someone tells me Apple really cares about user privacy, I point them to how Apple has been deliberately crippling their wares to actually spy better on their users. Some of the recent events include:

- Crippled macOS Mojave+ to let Apple know every app you open (in the name of malware protection, but sent unencrypted over the internet).

- Crippled macOS Big Sur to allow any Apple whitelisted software to bypass any user application firewall blocks and some VPN apps.

- Even ios, that has a whole lot of "do you give app permissions" for loads of stuff, leaves a glaring wide hole open as it doesn't let the user to allow or block an app from connecting to the internet (on WiFi).
political entities is not just people voted into office, it's also unelected high-level policy-setting bureaucrats like cabinet officials, chairpersons of the federal reserve, etc, who have the right higher education credentials that get them to the place where they are, so that the elected folks can claim "I know how how to hire the. best. people." so you must also consider educational trends in social sciences and social policy schools, like Princeton Wilson (is it called Wilson anymore?) or Ecole Sciences-Po.

You don't think those people are presenting graphs! with numbers! in powerpoint slides? Also, this is a classic: https://www.youtube.com/watch?v=JUvm9UgJBtg&t=2m40s
Numbers! It can't be wrong.
If we assume there are zillions and zillions of extraterrestrial intelligences broadcasting radio, chances are at least a few zillion base their unit of time on periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom (https://en.wikipedia.org/wiki/Caesium_standard)

Such civilizations would have a unit of time that’s a rational number of seconds. That would make such clashes possible (but very likely not likely, depending on how likely it is that a civilization uses caesium 133 as the basis for its clocks)
You don’t need to put others down to boost yourself.

Isn't that exactly what you did right here?
Strongly agree with this comment. We hide our elderly in sterile, grey corridors and leave them to die alone. We have totally de-socialized growing old and the process of dying, we've totally dissociated ourselves from it - and when it comes for us we will wonder why we said and did nothing about it.
You should be asking a lawyer, not HN.

If you haven't had a priced equity round, you should be able to sell restricted stock at par value (usually a fraction of a penny). Especially if your _upcoming_ round is a mere 5 million, the business today is probably basically worthless.
Nearly every feature of the face is different. Is there someone who works in AI imaging that can answer:
1. How this could happen
2. Why it's gone unsolved
3. Why this kind of tech is even attractive?
100% agree. I have a NAS for photos and media, plus a big USB HDD for ZFS snapshots of my machines - but all of this is homelab tinkering, not an actual backup strategy.

I realized in the last year or so that the only digital media I have which I would be genuinely sad to lose were wedding photos - so I saved those to 3 different cloud providers, made a Blu-ray copy, and a copy on the NAS. If I lose all of that in some tragedy, chances are I've got bigger things to worry about.
Enterprise != B2B. The only customers for AWS are businesses and always have been, end-users don't rent VMs.
I can understand ghosting from the ceo of a small company, or anyone in a small company. But I don't get it from a recruiter, especially an independent one. You would think they would want to stay buddy buddy with people who might make them money. Just because company a doesn't give me a job didn't mean company b won't.
I've gotten hired because of vulnerability reports. It helped skip a lot of the "convince me that you know what you're doing" phase of interviews and it was then mostly just social/team fit!

Apple might use these instruction in CoreML/Accelerate Framework and not integrated to LLVM as the author said:

> This is an undocumented arm64 ISA extension present on the Apple M1. These instructions have been reversed from Accelerate (vImage, libBLAS, libBNNS, libvDSP and libLAPACK all use them),

So we still cannot understand all of them from LLVM source code.
Right, I should have specified "Enforced laws". Considering how easy this one is to enforce, and how rarely it's actually enforced, it basically doesn't exist.
Nothing new, the former communist empire always lied about their problems and boasted about their successes. Nothing has changed, all the babushkas who sit around the entrances to apartment flats are still on the KGB (FSB) payroll and still report rumors, whispers and scandals to the local bosses.
The phone system. It seems like it's an unholy mess. I moved from the US to Hong Kong this year. I have a US number that I want to keep, and of course I need a local Hong Kong number.

So, the US number is on my Google Fi account that I pay to keep active and I get a prepaid SIM card for Hong Kong. I can switch the SIM cards if I travel back.

But why? We have two semi-independent networks, one for voice and one for data. The voice one is arcane, region-locked (local numbers cannot easily or cheaply make international calls), and subject to all sorts of restrictions and regulations.

The data network can send and receive data to anyone, anywhere in the the world, for practically free. Why are we even bothering with the legacy voice network at this point? Why can't I get one number that works anywhere in the world? Google Fi kind of does. It's great if you live in the US and travel a lot, but I've heard that if you're living outside the US and use it outside the US too much, they'll shut down your account.

Even porting the number to Google Voice isn't a solution. It only works in a few select countries and of course Google might decide to just shut it down at any time, so who knows.

Internet speeds are more than fast enough now even on mobile in most of the world that you should be able to handle voice calls with a data-only plan. If someone figured out the backend to connect it to the legacy telephone system, to just have one phone number that is independent of a carrier that you can access from anywhere with an Internet connection, they'd make a killing.
The first person pronoun you used ("I") strongly implied personal use.
Social etiquette for online spaces. Especially during a pandemic year, I'm surprised that this hasn't been more of a topic of discussion.

Mostly, if people do talk about social etiquette, it's within the context of not explicitly pissing people off, or looking good to your boss. I've never seen anyone talk about actually having good social interactions online.

I've had a few friends change jobs during the pandemic, and the thing they immediately tell me is that none of them have made any friends at work since starting virtually. They all just work on their own tickets, and whatever collaboration there is, is pretty transactional.

Zoom "happy hours" pretty much get dominated by two or three voices (usually of the most senior people) and everyone else just listens, because you can't have 2 conversations at a time. I've heard a bunch of the most cringeworthy techniques that managements have tried, to enhance socialization among employees.

In person, some things are pretty obvious. If someone is new, usually a good team will invite you into the conversation somehow. It would be weird if you got to your office and sat down and for days no one asked you anything about yourself. But it's perfectly fine to log into slack and have no DMs for weeks or even months.

Yup, this is how science works. You post a lot of covid conspiracy nonsense. Odd.
Do you know the name of the service? Blocking .xyz names as a whole would cut your company's employees off from accessing sites like Engine.xyz, ABC.xyz, and Starship.xyz.

Official DirectX headers available under an open source license
This so much.

Also I'm a big fan of chat-bots. How about a chat-bot that answers typical HR questions for an organisation?

"How much leave do I have remaining this year?"
-> 16 days.

"Book the dates 10/5/2021 to 11/5/2021 as leave"
-> Confirmed. Request sent to your line-manager.

etc...

I've seen so many bespoke web pages for these sorts of tasks. Including emailing someone in HR to do it for you.

I'm sure a system exists, but too lazy to google for it :)
But this highlights the difference between the two devices, stopwatches and timers.

A stopwatch counts up. Therefore, it makes sense to use the floor (4.99 is still "4", not yet "5").

A timer counts down. Therefore, it makes sense to use the ceiling (3.01 is still "4", not yet "3").

In fact this was a turning point in the original article: "rounding down . . . makes a lot of sense when counting up. . . . But for a countdown timer, this is counterintuitive."
Smartphone Keyboard

I cannot type a single sentence without making a typo and I have been using a smartphone for 12 years. I miss Blackberry's keyboard. At the moment I even cannot use my natural keyboard layout with a fast and responsive keyboard. I type 3 times slower on my phone than on a computer keyboard.

I think a large part of this (in the USA, anyways) is due to how modern cities are structured.

It used to be, 100 or 200 years ago, that your workplace, your home, and your usual hang-out place were all within reasonable walking distance of each other. It wasn't a huge deal to go out and meet new people, as you'd naturally bump into them every day.

Nowadays we have a large portion of people in bedroom communities, isolated in a sea of houses. They drive in isolated cars to their workplaces, swing by to get some Starbucks on the way in, and that's the extent of their social interaction. Apart from libraries and parks, there's not many places that you can regularly go and just "hang out" without spending money just to exist in that space. It's incredibly easy to go for weeks or months without any substantial social contact outside of work or your few neighbors.

I feel like this is a reason why internet organizations and social media have exploded in popularity, for that matter. It's the new "default place" to hang out and get social interaction, for better or for worse.

(I expanded on this in an article I wrote, https://invisibleup.com/articles/31/, if you want to check that out.)
Ask HN: What are your New Year's Resolutions for 2021?
You can run aircraft on electricity.

Locomotives run on electrical energy produced by diesel generators (because electric motors are more energy efficient), for example.

The limits are the cost and weight of the batteries and the charge time.
I can also suggest Lost Connections.

Last year I did everything I could, to go to tons of concerts, meet up groups, and alumni events. I had a very successful year in terms of meeting new friends, finding high income partners , and generally loving my life. I've long been disillusioned with social media, and I completely blame it for destroying a generation of mental health.

You need to make friends, and you need to go back to the old fashioned way of having light-hearted discussions. Versus nasty arguments on social media. I had to stop using Reddit for the most part, since no matter what I said people would attack it in some way shape or form. Even something as mundane as I find Java to be difficult, turned into a personal attack on my abilities as a programmer. Tons of people are obviously angry for whatever reason, and you feeding into their anger isn't going to help anyone.

I went to tons of meetups, and even though and all of these cases I was a complete stranger I was never insulted or made to feel unwelcomed. There's community out there you just need to seek it out.
I don't know if it's just depth issues, I think I saw a story about some sample projects in Alberta where they were looking for the right types of rock for the heat exchange to occur. It definitely sounded significantly more complex than just drilling holes, but finding areas with the correct properties to get worthwhile ROI.

One nice advantage is it draws on skills common to the oil and gas industries.
I understood the exact opposite that you have understood, and I find your comment quite uncomfortable, as a result?

The parent is clearly seeking to confirm serious long-term use, as you say, in considering the costs of failure cases.
Hot take: Within 10 years, I think there's going to be similar tech with personal cars, where you'll get automatically fined whenever you drive too fast, drive without seat belt, etc.

Then this information will be shared with insurance providers, and your car or health/life insurance will be automatically adjusted accordingly.

And, because why not, the dispute process is probably be some Kafkaesque ordeal.

Walnut Creek. Etc. They use the Bart to commute in from far away. But do remember a police officer can make 100k a year + they might marry a police officer.
My parents have two of these in the attic of their new house. I went up there over the summer and it was noticeably cooler than the garage where the access is. This is in the summer in Texas.

They also put their HVAC into the attic and the entire house is insulated with spray foam, so the attic only a few degrees warmer than the house below it.

I need to ask them what the energy bills were but I imagine they were low enough to prevent complaint.
Other vendors ML hardware is very much "A far away device over the PCI express bus which you give bunch of work to and later come back and see if its done".

Looks like apple has decided to make it very tightly integrated into the CPU. It means while doing ML operations, the CPU core can't go off and do other useful work. It also forces all cores to require matching ML hardware (or have a lot of OS complexity as certain threads can only run on some cores). The benefit is latency to get ML stuff done is lowered from microseconds to nanoseconds.

I suspect Apple probably messed up with that tradeoff... Very few applications can't wait a few microseconds for results of some ML computation...
Does anybody else know what the nature of the "tampering sensor" and why there are exactly 2 of them? I'm guessing the reason for multiples is redundancy, but, then, why not 3 or more?

Also, amusingly, I read "Fall detection sensor" as "Fail detection sensor" at first, and was really confused as to what that was. :P

Is this a question? I can't tell you if that's how you find my comment or not, sorry.

They wants a cheap tape device because they just want to use it in the home. Tape devices aren't cheap... because they aren't aimed at use just in the home.

They aren't aiming at home users - I think that's a simple fact not presuming anything.
Call me old fashioned but what's wrong with having a regular git repo anywhere you want with all of your dotfiles and them symlink those files to where they need to go?

If you wanted to you could && a few symlinks and other commands into 1 copy / paste'able command to get up and running really quickly. It's also painless to manage secrets by sourcing in optional files. It also works nicely when you want files living across 2 systems (such as WSL 2 and Windows) where on a Windows box you consider certain Windows files dotfiles even though technically they exist elsewhere.

I've been managing my dotfiles like this for a few years and it seems to be working out well not just for myself but others who have want to use them either partially or in full. I open sourced them here: https://github.com/nickjj/dotfiles

I purposely broke up some of the commands because I know that not everyone will want a 100% replica of my dotfiles. Folks copy / paste only the commands they want.
