"Concentrated benefits, dispersed costs." Farmers are highly organized and vigilant in defense of their subsidies and regulations, whereas sick people are not similarly organized and the policy connection to their condition isn't obvious. Concentrated benefits are what create special interests, which by their nature put their own interest ahead of the national interest.

> save their own customers unnecessary pain.

The pain is going to be that very few video games will be ported to OSX / iOS unless they dramatically increase their market size to justify the heavy cost to port to Metal just for those systems. If Apple cared about customers in this case, it would be an obvious choice to use Vulkan to pressure developers into using the industry standard rather than the Microsoft only product they are using predominantly now.
Not that I condone the usage of them but if they don't call that item a lightning rod I'll be sorely disappointed.

Calculus class simply provides a method for testing how good your algebra is. It's an elaborate algebra test. The stuff where you use calculus is the calculus test, etc. etc.

I know of a specific technique for teaching algebra - write down the principle used to justify each step in a derivation/solution - that will teach algebra cold but it "costs" too much so we don't do that.

I've heard at least one "officer" ( like dean ) level academic say "We use calculus class to keep the stupid people outta med school."

> I don't think removing the headphone jack is going to be as big a deal as everyone here makes it out to be.

> I have a pair of bluetooth headphones I use for the gym and I love them.

Yeah, that's why you don't see it as a problem. The majority of people still use corded headphones, some of which are high-quality, pricey investments that you don't just want to stop using. If you end up misplacing that little dongle, you can't listen to music privately until it's replaced. Seems like a downgrade in functionality, with almost no improvement, considering you are already using your bluetooth headphones effectively.

SSL Labs is a tool mainly used by the website owners/administrators, not so much by end users (and if at all an end user will then complain to the owner about a low rating).

Downgrading the rating because he used a "fishy" CA might motivate the website owner to switch to a CA with better standing. The bad CA will feel pressure to clear their standing.
It's hard to be in sitting position and also keep the cable flat and going to the side. It's usually at least hanging downwards, and also perhaps sideways if you're sitting lengthwise on the couch.
Mis-issuance is creating a certificate that is totally reasonable to create, just with the wrong validation. If you have a human step that lets you override the validation check, or if you get the validation logic wrong (e.g. WoSign/StartCom's thing where they allowed high-numbered ports), etc., you end up with a certificate that is otherwise reasonable for you to have created. And there's a lot of code that goes into validation. But there is never any reasonable use for a backdated certificate, and it's a very simple thing to double-check that your code does right.

If you give CAs a pile of requirements and say "Do not do these incorrectly" (which is what browsers do to all CAs), they can always argue that they made an honest mistake and they fixed it. Maybe they shouldn't have that room for argument, but they do. But if you say "Do not backdate certs," you've given them one thing to get right, that is hard to get wrong by mistake. At that point, a backdated cert implies either malice or losing control of the raw private key material, both of which clearly demand revocation.

I don't know what you mean by "fundamentally different" but there are definitely going to be demographic differences that the algorithm could use to predict race with good probability from hidden variables. (Where they live, for example.) History has an influence that's hard to remove from the dataset.

I'd guess that another reason this problem is hard is that it's about defining the goal correctly. It's not just maximizing repayment. There is some fairness goal that isn't well-defined.
When my grandfather died with cancer and fibrosis, one of the main complications involved in getting compensation from EEOICPA was the fact that his county doesn't have a coroner. They have a "medical examiner" who is based 70 miles away and never visits, plus some nurses he employs. As a result, death certificates in that county are only signed in extraordinary circumstances. The federal bureaucracy doesn't accept unsigned certificates for the purpose of establishing a cause of death. The county medical examiner is paid a flat yearly fee, so guess how many autopsies he performs?
What are they going to do with the 3.5mm audio jacks on Macs? So Apple removes the 3.5mm audio jack from the phone & adds a lightening port to the mac?

It makes me imagine how nice it would have been to ditch both the 3.5mm & lightening port & replace it with a USB-C port across product lines.

Obviously that would have been even more drastic in many ways, but I can't help but think that they have painted themselves into a strange corner.

> Uhh, personal experience? I've certainly bent my share of 3.5mm plugs, but I've yet to hear of anyone actually bending their lightning cable plug.

And in personal experience, I have never once damaged a 3.5mm plug, despite extreme rough use (and I mean the "extreme"). Can't say I have bent / never bent a lightning plug though, since I've never used an iPhone.
Even in models where race doesn't directly cause an outcome, a model's judgements may be biased against a race.

For example, suppose that (1) people can be green or blue, (2) green people tend to live in Idaho, (3) living in Idaho is associated with people not paying back loans.

A linear model where there are only non-zero, positive coefficients for the path p(green) -> p(Idaho) -> p(fail_to_repay), and p(credit_score) -> p(fail_to_repay) will create trouble, even though color does not directly affect repayment. If you use a multiple regression with fail_to_repay ~ B0 + B1Idaho + B2credit_score, it will discriminate against green people, by penalizing people from Idaho.

AFAIK, one of the points of the paper linked in the parent comment is that blindly using indicators like IP address may indirectly lead to discrimination against a racial group in this way, e.g. p(racial_group) -> p(a_specific_IP_address).

Maybe more relevant to your example, though, is that assuming whites and blacks have the same model in the "ground-truth" scenario I presented could cause a model to be discriminative (when it shouldn't be, because the coefficient for the path from p(green) -> p(fail_to_repay) is 0).

This specific issue is hairy, and exists for traditional approaches also.
I don't know if it's YC's fault per se, but it sure doesn't reflect well on them when the first link on their giant cheerful "look at all our companies!" list is a dead domain serving malware.

If you were charging what Slack charges, I wouldn't trust you to win against them. But you're going to undercut them by providing everything Slack does, for free, and aligning your financial incentives with another product? I've been an engineer at a mismanaged startup run by a hotshot CEO before, I know how this works and I know how much attention the zero-revenue product gets.

What your pricing tells me is that a) you have no interest in doing it as well as Slack does, and I'm already less than 100% happy with the quality of Slack's product, and b) you have much less chance of surviving than Slack does.

I suppose I am one of the "Slack fanboys" because of this response I wrote on Twitter https://twitter.com/geofft/status/679466421206687744. (Incidentally, that proves to me that you're lying, because that "so last year" tweet is from 2015, and in this article you're arguing that it's okay for you to say "so last year" because it's currently 2016 and you're talking about 2015.

> Billions of years from now, only one of these two galaxies will remain. Until then, spiral galaxies NGC 2207 and IC 2163 will slowly pull each other apart, creating tides of matter, sheets of shocked gas, lanes of dark dust, bursts of star formation, and streams of cast-away stars. Astronomers predict that NGC 2207, the larger galaxy on the left, will eventually incorporate IC 2163, the smaller galaxy on the right. In the most recent encounter that peaked 40 million years ago, the smaller galaxy is swinging around counter-clockwise, and is now slightly behind the larger galaxy. The space between stars is so vast that when galaxies collide, the stars in them usually do not collide.

Apple gets reportedly $4 per connector [1] for each 3rd-party device that uses a Lightning connector -- and that's with their new, kinder/gentler licensing scheme.

The adapter that comes in the box is the proverbial drug dealer's "first one" that's always free.

Imagine getting a $4 royalty on every pair of iPhone-compatible headphones that's sold in the world. That's worth a lot of free adapters in the short run.

Just as a first-order estimate: Forbes says that annual worldwide sales of headphones are $300M. If the average price of headphones is around 20 bucks (taking into account there are a small number of very expensive headphones but also a lot of cheap ones, that's probably high), that's something in the neighborhood of 15M pairs sold per year. If half of those become Lightning-connector equipped, that's $30M/year in revenue (on costs of zero!) going to Apple.

The connector could make the phone substantially worse as a phone and it still might be worthwhile. There doesn't need to be a compelling technical reason.

How they pair with non-Apple gear is yet to be seen, but the connection is BT.
Depends on what you mean. I have two pairs of headphones at any given time. One is a high quality over ear set for work/transit/home. The second is a "beater" cheap pair I bought at CVS that I wear when working out or walking. I lose the beater pair all the time, but don't care because they are cheap.
This is how I see it. There's no mention of Airpods using bluetooth, I'm betting that W1 chip is using a proprietary wireless protocol that keeps other manufacturers from easily/cheaply creating wireless headphones or using these wireless headphones on other devices.
They did* own the domain. I don't believe YC does non-equity deals.

I wouldn't mind a lighting port instead of the 3.5 mm jack on my mac. My last macbook, the 3.5mm jack was the one thing that failed, surprisingly.

I think that what successful people tell themselves is not that important of an issue. What's important is the narrative we give people who are not yet successful.

I have a friend who's smart, and is a really good listener. We have really good philosophical conversations, and he kicks my ass at board games. I've been wanting him to get into programming, because right now he's working as an assistant manager at a sandwich shop chain. He absolutely has the talent to understand programming, but he has never put an ounce of effort into it. He really likes the idea of making 50k/yr (which would essentially be a doubling of his salary) so he could be less depressed about finances.

I offer him help... I tell him how I self-trained into programming, without a C.S. degree. And he just has a total lack of effort, and I think that he just tells himself that he can't do it.

When we establish the narrative that the only barrier is hard work, then we ought to be able to motivate people because they'll recognize that most things are within their reach with enough determination.
