It currently costs about $2.50 to manufacture a battery cell. There are 7,700 cells in a standard battery pack. That’s $19,250 in cells before battery pack assembly.

I don’t know how they are making money on this. I’m inclined to believe they’re losing money, or someone is somewhere in the line.

Maybe they expect those battery costs to decline rapidly in the near future?

What do you think?
> Things like unknowingly racking up $2,000 in cell phone charges, or $3,000 in overdraft charges of $50 each for 60 different tiny transactions when you had no idea you were over the limit.

Was this predatory, though? Every phone contract I've signed for is pretty explicit about things like text message cost, data costs, etc.

From my perspective it seems more likely the parent's either didn't communicate that info to their daughter, or the daughter just did it anyway - both of which are parenting problems and not phone company problems.

Not to say the phone company handled it well, but the parent's signed the contract, too, so they should've had some idea.

EDIT: Now that I think about it more, I wonder if having the family on a business plan isn't part of the reason the phone company's being so stubborn about it?
No, it doesn’t.

I'm no security expect (and a bit of alcohol is helping write this), but I do honestly feel like people are shooting themselves a bit, especially to the point of using pass-otp, which is presumably ALSO where you're storing your passwords... It really feels like you've got two keys to a safe that two seperate people look after. But then decide to go for a beer together and one holds the other's key whilst they get another drink...

Sometimes conveniece definitely comes at a cost, and getting to the point of having an application to 'remember' your passwords (ignoring the fact the passwords can then be completely unique and more secure) and then duplicating the OTP keys (that are meant to be kept on an independent device) into the same application seems like a step to far.. at least for me! Think I'd prefer the inconvenience :/ No offense to anyone else's comments intended!
Recent past (e.g. in US politics) has shown that our society needs mechanisms to incentivize consensus. Google promoting fake information would get appropriate push-back and in the end help form consensus. Yes, even on political topics I'd be fine with that as long as they try to stay fact based. There is a lot of room for honest actors to discuss ideas. But I'm fine with society (including companies like google) pushing back once people (including politicians) go crazy with stupid positions (likely trying to widen the overton window to redefine the "reasonable center")

What confuses me about this is the tests were turned off because they were taking too long. But wouldn't the appropriate behavior there be "run a subset of the tests normally, but run the full test suite occasionally" rather than just disabling the tests completely?

Yes, it is. For Tesla it means, that they made up to their promise given when introducing the Model 3. Tesla has gotten a lot of critique after the Model 3 deliveries where much later than initially expected and the available versions much more expensive then the promised base price. Offering now a Model 3 for that base price should win them a lot of credibility back.

For the consumer it means, that the cheapest Tesla is now available for 35k vs. 42k vor the mid-range until today. Thats 7k less and make Tesla cars available to a larger audience. While I don't like how Tesla represents the prices with savings, the effective price gets close or below 30k, which is huge.

For electric cars overall it is also important. Tesla is the largest manufacturer of electric cars and the waiting times for the Model 3 are way lower than the competition. So this marks quite some progress in the availability of affordable electric cars.

> Firstly, kids on YouTube were NOT impacted by this

Unfortunately this is inaccurate. There are billions of daily adolescent YouTube users, some of whom entering puberty that were exposed and continue to be exposed to the recommendation algorithm that created this mess in the first place, and for periods running into hours every evening.

At such an early stage in development, it is absolutely the company's duty of care to ensure that a 5 year old is not being sent up a gradient of a recommendation system that is encouraging them (with the help of the comments just removed) to view people of their own age in a sexual manner. Not only were children impacted by this, but the mechanism that enables it remains active to this day.

I agree with the idea of allowing children outside, but as per my reply to your previous comment, not if that means spending all day in the back yard of the village creepy old man. Balance is required in every situation, and denial of the kind your comment is riddled with accomplishes nothing.
I didn't have a cell phone until I was able to pay for my own, but I know exactly how my dad would have responded to that: "If you don't like it, pay for it yourself." And then maybe would have added something about being responsible for me until I move out.

Twitch's model is terrible. Streamers have literally been banned for their chat going to other streams and causing trouble. Think about this for a bit. That's making the streamer responsible for the viewers, but they have no actual ability to limit what their viewers do outside of their stream.

Twitch only works, because they only apply their rules randomly to some people and only sometimes.
Does this have something to do with the decision of the owners of Tesla's convertible bonds if to get back cash or shares?

https://www.businessinsider.com/tesla-to-pay-march-convertib...

I mean that maybe if the bond owners see that Tesla is (really?) about to deliver the 35k model they'll opt less for cash and more for stocks? (therefore Tesla would have less problems with liquidity)

Slider phone reborn: Fxtec Pro1 delivers slide-out QWERTY keyboard
Our goal is making it super easy to build and run backends, and so if the first step was "install kubernetes" I don't think we'd have realized our goal. We don't have a goal of running these apps elsewhere. However, we don't like the lock-in either, as it's a blocker to people trying Dark, so we're trying to figure out ways to avoid that.

A current thought is perhaps allowing you to export your application compiled to Node or similar if you decide to stop using Dark. (Data is already easy to export, so we're mostly worried about code).

This is probably going to be the next blog post I write about this, because it's pretty front and center to the business.

This is the first time I've heard the concern of the project being too big for one company. I personally don't worry about it because it's so hard to move a small team in the same direction that I don't think a large community of volunteers will be a better fit.

>We don't really know if [mathematics] is sound.
My apologies, I was hoping to be concise. I meant to say that mathematics is sound relative to the assumptions, which is exactly correct. But if the assumptions do not hold in reality (and they never quite do), then the theory as a whole is slightly off. I mean to say that mathematics is never 'correct' with reference to reality, but of course is always 'correct' with reference to the axioms.
I've failed before, so here is the perspective of someone else who "fell off the ladder".

It is good to be a little scared of failure. But you don't need to be terrified. If you are still young, you will have time to recover. It may have its bad moments (https://news.ycombinator.com/item?id=13445141). If failure looks imminent, make a plan B. But you don't need to live in fear.

Instead, look at what other lessons you can take from meeting the box-lifting chemist. Here is a guy with an advanced degree in chemistry who is working for peanuts. This could be an opportunity for you and him. When I was bankrupt, a complete chance encounter led to the job that pulled me out of that situation. I was having no luck getting a technical job. But while I was getting a haircut for another failed job interview, I told the hairstylist how difficult it was to find a job as a physicist. And she said, "Oh, I know a guy who is looking for physicists". She gave my number to a physicist who ran a small company. He hired me and it was a mutually rewarding relationship. He also hired other down-on-their-luck physicists and programmers. One of the current directors of the company was notably hired when the company founder met him as his waiter in a Chinese restaurant. By keeping his eyes open, this founder got great talent at a good price and now his company pulls in over $50M/yr revenue.

If things go bad, maybe you'll meet someone who pulls you back up while working at Trader Joes. If things go well, maybe you will be the person who pulls someone up.
It's a business contract. Companies seem to be a lot more hardnosed with these things about openly segmenting their offerings, and being somewhat cruel about it. I bet there's one where you can send literally 1m international texts a month for free, for example, and it costs, like, $2.50/mo more.

But these people didn't pay for that one. And so here they are.

As a business owner you are expected to be a bit more on top of this stuff.
"We are also making it much easier to try out and return a Tesla, so that a test drive prior to purchase isn’t needed. You can now return a car within 7 days or 1,000 miles for a full refund.

I was the founder of SkyPhrase, a natural language processing startup that Yahoo acquired in 2013. Natural language was also a focus of my AI research. We have some ideas on how to apply that to this project, but they will probably have to wait at least a few months.
They've been doing that for a long time, trying to explain in TCO terms instead of sticker price. It can be somewhat misleading at times but I get the rationale.
This is true, as it doesn't need to be a matter regarding only the creeps. I was thinking sociopolitically, where adults related or not make the decision to use minors as props, whether for a thing as big as ad campaigns or as small as for social brownie points. As a grownup, if someone were to post my image without my express permission I could pull some legality in my favor. Children generally don't have the same resources, lacking their own guardianship. I'm just saying that until they can legally make such decisions for themselves, privacy should be the standard, to save them from embarrassment or abuse. We must all decide for ourselves what to share of ourselves.

Tesla had to do this. They've filled the order backlog of customers who were willing to pay more than $35K. They still have many on the list who are only willing to pay the original $35K. So it's sell at $35K, cut production, or park the unsold cars in a lot. Happens all the time in automotive.

Big question is, does Tesla make a profit at that price?

$8K more for 50% more battery. Or $24K for an entire large battery. Big markup there.
One thing that always bothers me about articles like this is that they compare gender equality among young people, which are much better than they ever were, with gender equality among people who were born 50-60 years ago and thus obviously grew up in a different environment regarding gender equality. C-suite gender distribution will always be a pretty lagging indicator of current gender equality.

But otherwise this article makes some good points. I remember in school seeing lots of people (almost all girls) diligently highlighting and color-coding, taking extremely detailed and clean notes, and otherwise spending a lot of time working on academics outside of the metrics which were actually being measured (homework, projects, and tests). It always struck me, a male, as an inefficient use of time. But I was almost on the entirely opposite end of the spectrum, with all my class' papers in one disorganized pile and generally doing everything at the last minute. I wonder if this stereotypical girl approach to doing academic work is due to socialization or some other factor

I don't believe people's unwillingness or inability to read and understand the contracts they sign constitutes predatory business practices. Unless they were misled when signing the contract, I don't see why this is a problem. Not only are there other phone services you can use if you didn't like this pricing structure, you can also just use a non-sms based messenger, like signal or whatsapp.
Funnily enough, the listed MSRP usually much higher than actual dealership price.
Hi— Jared from Pagedraw here. (Stunned that this is the top comment on HN.) I stand by what we wrote 100%, but to add some color:

I don't want you to think we didn't care about performance. We did— a lot. We just think most people do performance optimization badly.

There's a lot of superstition on the internet about how to structure your code so it's fast. In our experience, following this advice usually does not make your code fast. Most people have bad intuition about performance.

To counter this, you have to constantly measure the performance of your code.

There's 2 parts to this idea.

1. Most things are fast enough that optimizing them is not worth making the code less readable, and is a waste of time.

2. Measuring, rewriting, and repeating is the right way to do performance anyway, full stop. There's lots of superstition around performance, which is absurd because it's extraordinarily measurable.

For point 1:

We goalled on a clear and flexible style, which helped us move incredibly fast with very few people. See https://norvig.com/spell-correct.html for an example of a golden piece of code in this style. Rewriting for performance takes moves us away from that goal.

Most of the code we wrote was fast enough (<2ms) that making it faster wouldn't be noticeable, so it would definitely be a waste of time to optimize. Making code that's 0.1% of your runtime 100x faster only makes your latency <1% lower.

It's not because we're brilliant coders: we just realized that most of the code we wrote ran on arrays with few enough elements that even O(n^2) algos could run in <1ms. Some of the code we wrote ran on a server, where network was the dominant factor, and we could always just scale up our servers with money. Some of the code ran on click, where it could be as slow as 5 seconds without the user really caring.

For point 2:

There's no such thing as “fast” code and “slow” code— you can put in the work to optimize any piece of code, and make it incrementally faster.

Because you can put in work to optimize any particular code, we either budgeted hours of engineering time for performance, or set performance goals. In either case, you want to spend your time optimizing the code that's the slowest, so you get the most “bang for your buck.”

Most people have terrible intuitions about performance. We certainly did— if we'd prematurely optimized the things we'd thought were going to be slow, we'd have wasted a ton of time

I felt there were lots of superstitions about performance that were just wrong. For example, considering big-O time complexity was often wrong for us, because our n was usually pretty low, so we were dominated by constant factors.

Performance is incredibly measurable. You should always measure, rewrite, and repeat until you hit your perf budget. Otherwise you're just shooting in the dark.

Because we goalled on clean code, tearing and replacing whole subsystems for performance was relatively easy.
Then we'll agree to disagree. I think you are wrong on so many points here, it's clear we're not going to agree, and probably won't find common ground.

Thank you, by the way, for your references to various published material. FWIW, I've worked with BCPL, C, AWK, C++, Unix, Linux, GNU, and much, much more, for the last four decades or so, so I'm not inexperienced, and I have read most of the classics. That also doesn't mean I'm right, but it does mean that I have a basis for my opinions.

So thank you for your offer to school me, but I'll decline, and, as I say, accept that we disagree.
This is less secure than not having 2fa at all.

2FA means two factor authentication. It's a guarantee that even if someone hacks your password or steals your computer, if they don't also have physical access to the secondary device (phone, yubikey etc), they won't be able to gain access to your account.

If you put the secrets of 2FA into the same computer, you are back to 1FA.

However, you end up being less secure than not enabling 2FA in the first place. This is because when you enable 2FA, they can disable the regular checks that they have for 1FA accounts. It will also be incredibly difficult to regain access to the account if you don't have access to 2FA devices.
There's no need to monitor the content of the messages in this case.
The gas savings is definitely shady.

But including the federal tax credits and destination fee is fair I think. As far as I'm aware, no auto maker includes the destination/docs/handling fee in the MSRP. The Tesla fee amount is comparable to other automakers also (it's on the high side at $1,200; but it's not too different from Toyota's $930 and Honda's $920). Presuming your location due to geolocation is a bit too far (but that's debatable) since they didn't disclose that immediately up front.
We're absolutely willing to oppose organized and targeted manipulation of votes/flags (and we write a ton of software and meta-moderation features to do so), but that's not what's happening. What's happening is legitimate division and difference of opinion. If it weren't so then it wouldn't be a controversy—and sure it is.

Edit: I don't actually see the pattern of downvoting that you're describing in this particular thread.

Most parts that aren't near Times Square, IMO, aren't very touristy. Did you live in the financial district?

Do you enjoy nightlife? If not, you may not enjoy the city as much.

But there are frequent live music shows, good bars of all types, great late night food options (food trucks, pizza spots, Japanese izakayas), beautiful parks (I liked Prospect Park especially, but Central is gorgeous too). And if you're a single heterosexual guy in your 20s, the dating scene is pretty incredible. It seemed at least decent for other orientations too.

But yeah, there are overpriced brunches too. I tended not to do that as much because I'm not really a fan either.
