It's purely the brightness. If you're in ambient bright light you don't develop myopia even if you're looking at nearby objects the whole time (e.g. reading books or a phone), if you're in a dim environment you still (are at statistically elevated risk to) develop it even if you're looking at distant objects. This is something they've had to keep doing bigger and bigger studies on because everyone who hears about it has the same kind of thoughts as you did.
First time I've seen this show up on HN. I lived there too :). I still live in a co-op to this day.. actually one a few blocks away from Stanford.
Fahrenheit is a pretty nice scale for weather temperatures for humans that produces nice round numbers. 0 is really fucking cold, 100 is really fucking hot, and both are somewhat rare but not impossible numbers. Mild weather is in the 70s, which is like getting a C on a grading scale.
All those languages have if-expressions, which is all ?: is.
Your comment reminds me of Steve Jobs amazing commencement address to the Stanford Class of 2005.

I try to watch it once a year, especially with grad students and postdocs. Gets better each time.
The cheapest iphones are solid. The cheapest android phones are crap. On the higher end they are more comparable.
Well said! Unless the personal life is happy (stable dependable lovable relationship like spouse/significant other), it's hard to succeed in professional life.
Very nice! What ended up happening on the small day boat you worked on?
Assuming your question is not rhetorical: because it probably does not predict what you think it does.

People with higher incomes probably buy more expensive phones. You already have their income on a loan application, so you don't need a blackbox NN model to confirm it.

Throwing in a bunch of corrolated features into a model won't help improve accuracy.

But if you throw in a bunch of weak features that together sum to a predictor of race (or other protected attributes), then aside from being grossly unethical, may well be illegal.
They've fixed the import / modules situation to a point where it's usable and much improved, and generics have been added.

However, the issue this brings up about structs / types not explicitly declaring which interfaces they implement is a real and unaddressed problem, especially in large codebases. The only tool that I'm aware of that finds implementations is GoLand, at steep JetBrains prices.

Figuring out what type an API is asking for should not require reading every line of code in the package, and slows down every developer of large Go projects
You may buy an EV before such a battery is widely available in production.
My general rule is that if its been working reliably and contributing to revenue generation its not bad code. We have code over 10 years old that looks bad by today's standards but since those are parts of the system that almost never need to be changed then there is absolutely no reason to try to make them better because they are already functional and battle tested. The concept of modern code is just a compulsion of developers to sprinkle their own beliefs of good coding standards over code that is application critical and should be resisted unless there is a good case behind it (e.g those components regularly cause instability or need to be extended)
That’s why the highest ranking phone under $500… is an iPhone? It honestly makes the most sense to buy the budget iPhone if you are on a budget. They’re supported much longer than other phones meaning not only are you not paying a whole lot up front, you’re also able to meaningfully use it much longer than competing android phones.

I am pleased to see your rebuttal. Frankly, I initially thought your indignation was disingenuous. Now, I think we have both read that comment differently.

>> Would they have done the same thing if animal rights protesters, or the Proud Boys, or whoever came and someone thought they were on Amazon property illegally? I think so.

I read it as: take any arbitrary group of people who might organise a protest from any arbitrary political or social position "or whoever". Regardless, Amazon would have reacted the same. There is no implicit comparison to insurrectionists in such a reading.
I think the reason why they focus on social media is because it is so much more effective at capturing our attention. This is because social media giants know to a high degree of accuracy the profile of their users. Besides basic demographics, stats such as the amount of time spent looking at a entertainment video can give away more information about the user’s interest than they know themselves.

Regarding television being king, According to statistica, the number of social media users in the US is 294 million (https://www.statista.com/statistics/201182/forecast-of-smart...). Whereas the number of television users is about 305 million (https://www.statista.com/statistics/243789/number-of-tv-hous...). Even though these numbers are comparable now, the increased effectiveness of social media and its popularity among younger populations makes it a more effective means of mining our attention than television in general.
I have no first hand experience to offer.

But remember all the iPhones are relatively premium phones (starting about $430).

People argue about the Pixel and the Galaxy and such. That hardware is probably relatively reliable.

But there are also things like the BLU J9L and CellAlure Fashion C. Both are $100 new from BestBuy unlocked. Or the free-on-contract handout phones various carriers have that may be complete crap.

So the Android average may be relatively bad because it’s dragged down by bargain basement junk.
That's good news, pending actual pricing when commercially available.

But the real meat of the EV revolution will probably be high density LFP (300-400 range cars) and next-gen sodium ion (200-300 mile cars) which require no nickel or cobalt, or for sodium ion, not even lithium.

This is based on production densities that are supposed to be available in production late this year (LFP) or next year (sodium ion)

Improvements in any sector or aspect is a good thing though. There will be cells needed in dozens of applications, from container ship to bicycle.

Edit: I reached the posting limit, so here is more on the higher density LFP/sodium ion:

230 wh/kg LFP:

https://pushevs.com/2022/03/29/guoxuan-closer-to-mass-produc...

160 wh/kg Sodium ion:

https://www.electronicdesign.com/markets/automotive/article/...

So my napkin math says that the densities listed should enable a 400 mile Tesla model S type car (especially since LFP doesn't need as much cooling and has higher density cell-to-pack), and sodium ion should do about 70% of that, or a 275 mile model S large car. Napkin math is derived from looking at current pack densities in Tesla cars and comparing that with 90% of the cell densities in the above articles (which these should be able to achieve in pack density with cell-to-pack and that these chemistries don't need as much active cooling systems). The current model S from googling seems to be at 186 wh/kg at pack level. 90% CTP 230wh/kg LFP should be 205+ wh/kg!!!

That may also enable large scale 50-70 mile range PHEVs, and even cheaper EV bikes/scooters/lawnmowers/etc. LFP also has better capacity retention,cycle endurance, and temperature endurance typically.

But the Sodium Ion might be the real revolution from a city car perspective for places like China/India where you'd need a billion or more clean city cars. A cheap 100-150 mile sodium ion car is just what these markets need.
I'm sure there's a reason (probably related to lawsuits, liability, or negative publicity) for universities cracking down on student-run housing options, but it flies in the face of the idea of "residential education" - that students could actually learn something by being in charge of their residences.

Since university administrations can just wait for undergraduate cohorts to graduate, it's up to alumni, graduate students, faculty and staff to push back, but they rarely do. The point about eliminating certain houses during the pandemic makes sense - the administration had the advantage of undergraduate turnover (and loss of institutional memory) as well as pandemic stress and amnesia.

If we look at Yahoo! or Google, which originally were hosted on Stanford's network (though Excite was hosted off campus?), or Cromemco, a computer company that was actually started in a graduate engineering dorm at Stanford in the 1970s, we can see that ultimately it may be in the university's (financial) interest to sometimes let students do what they want.

Then again Facebook originated as an abuse of Harvard's undergraduate face book, so maybe some cracking down isn't entirely a bad idea.
It was stories like this that made me realize that I don't have to be a super-parent to be a good foster parent. I can be a regular good parent and still be way better than the alternatives that would otherwise exist for a child that's placed in my care.

Realizing that there are kids out there that need someone to take care of them and that I don't have to be perfect to provide that care is what really got me thinking seriously about foster care, instead of thinking about it as "something other people do."
Guessing it’ll need a megawatt charger to pull that off on an EV size battery.
There are already plenty of tab managers that work on desktop, and they shouldn't require a rewrite to work on mobile. I think Mozilla just hasn't finished making Firefox mobile support all the web extension APIs yet, so that's why they haven't opened the mobile app up for installing arbitrary extensions
There are no third party app stores on iOS, so I'm not surprised at all.
Update Jan. 20, 2021: The North America myopia trial is nearing the end of its second year and it is closed to enrollment. Based on the one-year data, the eyeglasses have regulatory approval to be sold as medical devices in Europe and Canada. They are currently being sold in Canada under the brand name "Kikko." Researchers anticipate regulatory approval in the United States in about a year that will be based on the two-year results. People can go to the Kikko website https://kikkovision.com/ and sign up to receive updates about U.S. availability. Once they are approved in the U.S., people will be able to buy the glasses from their optometrist or ophthalmologist.
I know Apple worked with various high end hotels to deploy their phone/watch as a key offering. Going to be a long time before that’s in Holiday Inn or La Quinta.
Rust has if/else (ternary) and match (N-ary) expressions, so it doesn't need a separate ternary operator. All of the other “C replacements” listed (which are a weird list for that description, especially Elixir, but whatever) have at least if/else-expressions, which, again, are ternaries.
Private sector unions are a simple matter of free association; if they kill the host, so be it.

In the Navy, we called a public sector union a 'mutiny'.
I have absolutely no idea why they haven't increased the number of residencies available (not a field I work in), but the process to become a vet is similar to other medical specialties. There's a limited number of slots available annually, and the number of slots is lower than the number of people retiring, let alone accounting for industry growth.
2 years is less than I’d expect. I remember an 18 year old kid got 1.5 years for creating a variant of the Blaster worm (not even the original), and I don’t think he even profited from it? This guy is a fully grown adult, created an illegal business that performed 200,000 DDOS attacks, likely made millions and caused immense amounts of damage, and … just a 33% longer sentence?

Although, maybe “hacking” type convictions are getting lighter over time?
I don’t know OPs location but if they’re in SV - series anything isn’t enough to afford the Bay Area long term unless the wife is working at FAANG.

I presume OP doesn’t live in SV because no way to buy just about any home here on a startup salary. Homes where I am went from $2m to $3m in last couple years. These pillars of dust full of termites somehow managed to get even more insanely expensive. I literally didn’t think it was possible to see a shitbox going for $3m outside of Palo Alto but I was wrong.

No as long as they would selectively pass only articles which look anti-Bezos at quick glance but are actually supportive with full read.
Thank you for the sincere reply.

I think it’s a lot of rules - you even allude to there being infinite - and while each might be easy to understand for an IT crowd like HN, I think some of them might be hard to understand in the general population.

A lot of them looks like the product of hard learned lessons too.

So the sum of the whole thing doesn’t add up to simple.
People wear the same glasses for everything because it is hard remembering where your glasses are, carrying them around, and swapping back and forth every couple seconds.

Its a horrible user experience
I don’t know how it compares. The source I could find lists 380Wh/kg for Tesla batteries. This article claims up to 550Wh/liter. Also sometimes they discuss the energy density of a single cell and sometimes of the whole battery.
They do. Not just for me, but for many Americans in some study I found previous, and many people I've talked to. However there is a conflicting Philippine (iirc, or Malay) study that concludes the opposite. Most go with this latter study, though both are likely correct, myself having experienced the former.

Having explained this to my optometrists they will take me seriously and give me most any prescription I want, though unfortunately I don't exactly know what to do. I just make sure I have dedicated outdoor glasses and limit screen time with them.

I avoided wearing contacts for a while due to this but also other concerns. I think this may have limited my romantic success somewhat, at least at the time. In retrospect contacts with readers may have been the better option.

I keep holding out for LASIK but don't know how much longer I should.
That's pretty much any "respectable" industry really. The government will usually take their cut, but it'll be far less than the profit a company's illegal actions brought in, and the victims of the activity get shafted instead of being made whole.
I believe there used to be a "wormhole" static video conference linking cafés at MIT and Stanford. You could sit down at a table at MIT and talk with people at Stanford or vice-versa.

It's a great idea that should be deployed not just at universities but other places as well.
When developers who usually make 6 figures of money complain about $90/yr IDE price I just cannot help laugh. Actually it's even better... the price elevators down from $90 -> year2 90 - 20% -> year3 90 - 40%.

Over three years that's like $150-$200 total and it will save you so many headaches. But that's a steep price? Are you kidding? Why do developers hate tools that cost money when they save them time and allow them to do more?
That sounds like a much older congregation. If the worship has a guitar, it’s probably using ESV.
you can add cargo to that list as well.
To an 80% charge, all modern cars with super fast charging (Tesla Model 3/Y, Ioniq 5, etc) can do it in around 15-20 minutes assuming you're connected to the fastest charger available.

The double time to full (vs. just to 80%) is pretty comparable to other batteries though, where that remaining 20% takes almost as long as the first 80%.

So, it's a lot faster. That said, I'd be interested in lifespan. They claim 'high cycle life' but don't actually put any figures around that.

The article states that the capacity figure is just a 'goal', not something they've actually achieved... if I'm reading it right, so it's a bit meaningless at the moment.
That's like asking why there is a car doing 60mph on the highway when everyone else is doing 75mph. If they are driving a VW, would you assume that means VW makes slow cars?
I will trust our younger readers to draw their own life lessons here, but the general model being described is that of the "company union." They were outlawed in the United States in 1935.
1. This isn’t what the subject of the video is. At all.

2. We shouldn’t base scientific measurements off how things feel. Imagine this in any other context. Speed limits in what “feels fast”, weights in what feels heavy etc. it’s ridiculous.

> making students pay in person tuition for online school

Bad enough at any school, but imagine borrowing $60K or more to pay for 9 months of Zoom university.
While serving a mission for my church, a fellow member bought me a copy of “Strongs Exhaustive Concordance of the Bible”. I found it really fascinating to flip through correlated terms and be able to draw conceptual lines between them. It was the first time I’d ever come across something like that. It strikes me as something that is relatively rare simply because what the Bible is, in terms of popularity and commonality across the western world.
Parts for used imported cars are extremely difficult to find, with the prices up exponentially.

With new car sales in Russia down over 80% in May, the pressure will increase the prices of used cars.

One way or another, Russians are paying for the barbarity of their countrymen, and the price they pay will only continue to get higher.
> I absolutely despise most third party Android vendors.

Years ago I got a Samsung Galaxy 8 which came preloaded with CNN and Facebook. After uninstalling those apps, I poked around with adb and found services still running for CNN and Facebook. Made me also despise non-Pixel devices.

For a long while my daily driver was a Pixel 4 (probably my favorite phone hardware of all time) running GrapheneOS and then eventually CalyxOS. If I were to ever switch back to Android I would 100% go back to Pixel running CalyxOS. I absolutely loved that setup.

Things that keep me on iOS:

- On-demand VPN. I use Wireguard and it is unnoticeable when it automatically turns on when I leave home. I was able to use Tasker on Android to unreliably replicate this functionality.

- Apple Shortcuts. Android could really benefit from a first-party automation toolset, Tasker is still pretty mediocre compared to Shortcuts from my somewhat recent tinkering.

- Apple is a decent steward of data and I'm encouraged by the continuing privacy features they release (Private Relay is awesome). Despite this, I try to avoid the walled garden as much as possible. Homekit is one area where I've totally invested into but could switch that out with HA if I ever switched back to Android.

Things I miss from Android:

- Sideloading. F-Droid is the best -- I miss sideloading so much and hope that Apple is eventually forced into allowing users to actually sideload (not the temporary 7-day renewal you are forced to do). Because of the ability to sideload you can embrace an open source ecosystem so much more than you can on iOS.

- Custom, debloated roms.

Aside from those drawbacks I am a big fan of both Android and iOS and find very little difference in how useful each OS is to me.

EDIT: fixed formatting and minor typo
The capacity of an individual cell doesn't really matter, because you can linearly scale up the energy capacity and power. If you can charge a single cell to 80% in 5 minutes, then you can do the same for many cells simultaneously, as long as your power source doesn't become the bottleneck. From the perspective of battery technology, what matters is energy density, power density, and of course manufacturing cost.

But for what it's worth, the linked presentation[1] includes some test results from 2.7Ah cells, which is about the same as the capacity of a common 16850 cylindrical cell.

Kids aren't interested in how much you have, or where you came from. They won't necessarily be "grateful" in what you provide for them, because they don't quite get that "being provided for" isn't supposed to be the norm. They show their gratitude by growing and thriving, and eventually when they grow up, they'll finally "get it" and know. Love them, provide for them, survive their moments of immaturity, console them when they need it, guide them even when they don't want it, and they'll be come a reflection of what you want the world to be.

It's the foster kids who become permanently adopted who are a little bit different. They're the ones who understand that love isn't to be taken for granted, and so they appreciate it when you become the parent who will always be there for them, in ways that people who have never been so alone will ever fully understand.

Why do people expect energy to be free to charge their car?
Another option for families that are not in a position to make a long-term commitment is respite care. Basically being available to take kids for a night, a weekend or a few weeks. It can allow foster parents to have a break (or sometimes an emergency comes up and they need a few weeks to deal with it) and it can also provide kids with a place to stay when they are between foster homes and there's a gap in availability for whatever reason. Or when they have to be removed from their birth family suddenly and there isn't time to find a long-term placement option right away.
High-density LFP sounds amazing. Where can I read more about it?
>The cells also surpassed 1,000 cycles while retaining 93% of their capacity

1000 is a short count i wonder if the capacity drops off suddenly after about 1000...
Public DNS servers have their place. 8.8.8.8 and 4.2.2.1 are pretty popular. DDoS attacks don't depend on DNS servers either so you can't solve the underlying problem by making them go away either.

I always thought it'd be great if the EFF ran a public DNS server. At least you could trust them not to use your requests to build a profile of your online activity or redirect you to ads.
The editorial details exactly how societal class-ism starts.

This study is ridiculous. I have an old android because they took SD card support and headphone jacks out. I also spent money on a fairly expensive car, and have no aversion to buying tech that isn't disposable. just like many others. What puts me off apple devices most is probably this brand of elitism based on class and racial undertones. They are devices, not personality attributes by which people should be measured.
