For better or worse, this is what the consumer expects. First of all, if they don't get a refund through PayPal, they will just get a chargeback through their credit card, and you're still screwed. Second, you're competing with large online and storefront merchants who offer no questions asked refunds. In fact, offering generous refunds may be cheaper than quality control for those merchants.

Those merchants make money by having a pretty good statistical handle on the rate of returns, and baking it into their prices. The trick is to make sure your cost is low enough relative to your selling price. Granted, a big vendor has an advantage in access to good statistics, whereas a small business can't plan for it very well.

But I think it does create a situation where PP or any other payment processor works for some businesses and not others. You have to decide if PP is the right technology for your business.

It's a different argument because it addresses a different point: "unsweetened works just as well in any scenario." Clearly, that's not the case as the sweetened and unsweetened versions are not comparable due to taste.
Just subpoena the intel agencies? Just because they haven't released the evidence publicly doesn't mean it wouldn't seem reasonable for the intel agencies to assist the case.

It's not like you're storing card data because you're using Stripe. Stripe also allows 3D Secure to be used, so Stripe is clearly the more secure option compared to PayPal.
The bug looks like it occurs because the date picker aligns days/dates from 2017. February and March both begin on a Wednesday in the screenshot. I don't have iOS to test, but if this is the case, a flight for 1st Jan 2020 will incorrectly be aligned under Sunday instead of Wednesday.

Pretty poor bug
My first instinct was that this was bad and designed to spread misinformation. However, on second thoughts, science is not religion and can stand up to sincere challenges and questions. In fact, if these people are serious and dedicated to truth, perhaps they will advance science by challenging assumptions and asking new questions.

I think we should welcome it.
I work on a hotel OTA and this and similar situations consume a disproportionate amount of our dev time, and I believe it should. So much travel software relies on third parties and problems with eventual consistency (read timeouts) mean that often either the customer is told their booking failed when it succeeded, or it fails after payment is taken.

We try to ensure that our support tools make these situations, and the resolutions, as clear as possible to our customer agents.

Ultimately, we are on the hook for this booking so it's in our interest to get it resolved for the customer so they are happy. Our stats show that this only happens to 0.5% of bookings, but if they aren't handled well, they take up a much larger amount of support time and then end up with an unhappy customer.

Over the last few years I've come realise that this is a fundamental cost of building travel software. You can't gloss over these problems or push them back on the customer, otherwise you simply won't have any customers left.
Production reliability and user privacy are different goals. It’s true that a generally tighter ship will be better at both, but they are often in direct conflict. “Fail secure” is an outage waiting to happen.
I think Gradle is mostly implemented in Java. I wouldn't think its speed is limited by the language of the DSL. Although I would guess startup time is longer as it definitely does have to load up groovy in the classpath and initialize all its classes.
We desperately need another major video streaming site. Google has been consistently acting in an atrocious manner for users and content creators, with negligible cost due to their functional monopoly - even massively popular creators are able to recover their videos only in the rare situation of widespread media attention [1].

Do you never buy anything online? Or play an online game? Or use Google maps? I can think of lots of websites that I regularly use where JavaScript is important. I agree it is best to limit it, but it definitely has lots of uses.
Except challenging evolution is like challenging F=ma
I don't think its inconceivable, but comparing it to a hedge fund makes it look pretty crazy. First note that they look more like a prop fund, in which typically returns are labor-constrained rather than cash-constrained. Annual returns there aren't really comparable to investing, as they're more performing services (like arbitrage) for the market than putting in money. Second, the fact that being able to invest is a perk of employment means that part of their pay structure is via Medallion returns. Income that other firms would have to subtract from returns because it is spent on payroll still counts for Rentech even though said returns are going to employees.
Three letters: TSA

I have a complete lack of faith that any institution whose day-to-day experience completely differs from their catastrophic risk scenario is ever truly prepared.

The personal and organizational strain of maintaining constant vigilance against an invisible enemy is simply too high.

People get lazy, complacent, and think they're more prepared than they are. That's just human nature.
Yes, there is no need to have a PhD to do ML, either applied or research. Not to say there isn't good research using advanced mathematical/statistical methods, but most of it is not. It's entirely a signaling game.
To be fair, custom Javascript on a website can do things that are too rare to be baked into general browser behavior, such as adding colors or icons or text to certain dates, date-range validation, disallowed dates, etc.
maybe we do need some kind of registry, tree based key-value with an API for access.

>That's all well and good, but the judge is quite clear that it is 'the defendant’s ... reference to a “lawyer dog”' that is 'ambiguous and equivocal'.

In that it was not a clear and unambiguous invocation of the right to counsel.

>I'd be curious about your views on why the judge chose to include that sentence if the 'reference to a “lawyer dog”'' wasn't relevant to his decision?

I don't know why he chose to quote "lawyer dog" and not more or less of the defendant's quote. I'm not a mind reader. But when he writes:

>I believe the defendant ambiguously referenced a lawyer

It's clear that the ambiguity he is arguing does not derive from his lack of knowledge of what a lawyer dog is.

Ask HN: Are we training Google's self-driving AI by using reCaptcha?
Am just curious, I can't help but feel like Google is using me to help train some sort of AI system when I click on crosswalks, street lights, cars, etc, often several times in the same day. Also, what are some of the alternatives to Google's reCaptcha?
Two of the first questions to ask are "could a competitor do better in this regard?" and, if the answer is in the affirmative, "Could a competitor replace PayPal by doing better in this regard?"

For a number of the most successful e-commerce fields (those having a large market that can be served in an almost completely automated way), the answer to the first is probably yes, but only in a tiny fraction of all transactions, and only by spending a lot more on human customer service. Consequently, the answer to the second question is probably no.

There is also the asymmetry with regard to whether PayPal leans towards the customer or the vendor in a dispute. The former attitude tends to lubricate commerce, while the latter applies the brake, so it is actually to the benefit of vendors as a group, as well as customers (and also, of course, itself), if it does the former. If customers regard PayPay as the preferable way to do business, the pressure is on vendors to use it, while vendors who spurn it in favor other methods risk losing business to competitors.

Because PayPal made a number of smart choices, it offers benefits to both sides of a transaction in the vast majority of cases, and that is pretty unusual (compare it to, for example, the credit rating agencies.) It is in a sweet spot where it would be difficult to compete either by reducing costs or by improving service, and that sweet spot is defined by what it is currently technically feasible to automate. That sweet spot will move with technological developments, and PayPal will need to adapt accordingly to stay in it.
Class action lawsuit? If it's this blatent why hasn't anyone been taken to court by a large group of the wronged.
The issue with PayPal isn't that they freeze accounts, but that have a history of preventing people from getting at their money for months without justification.

It was never about returns exceeding borrowing costs. Rentech is probably the greatest money manager of all time. They can make returns that exceed the borrow costs.

It was always about the amount of borrow available, and the tax paid on the gains. The (illegal) strategies they used allowed for much larger borrow amounts, as well as only paying long term capital gains, when in reality there were millions of trades.

The simple setup: Rentech pays the bank $1B for a call option. The call option is on a $10B pot of money. The bank then hires Rentech to invest the pot of money for them. After a year or two, Rentech then exercises it's call option, which gives it everything in the pot except the bank's $9B plus a fee. The banks loved this fee. And since this was a year long call option, all gains are taxed as long term. They avoided $6B in taxes doing this.
Not emacs (it means kill-region there, which deletes the text between the cursor and the mark and saves it in a holding area, fairly close to what windows does when you hit ^x, except the holding area is fancier).

This readline behavior follows a Unix tty driver. I'm not sure off the top of my head which one introduced it. I don't think it was on xenix but am pretty sure some 4.x bsd had it.
Ask HN: Resume templates compliant with ATS?
I recently came to know that whenever we apply at a tech company, our resumes are first parsed by ATS (Application tracking system) to find out if our resume is relevant to the position. I also read that several of the resumes people use are not parsed well by ATS, resulting in an immediate disqualification. What are some of the resume templates which work well with ATS?
Median Sales Price of Houses Sold for the United States
If you read the two paragraphs after that:

"The state protects normal religious activities. No one may make use of religion to engage in activities that disrupt public order, impair the health of citizens or interfere with the educational system of the state.

Religious bodies and religious affairs are not subject to any foreign domination."

The Chinese government justifies their actions in Xinjiang as an attempt to prevent extremism (terrorists disrupting public order) and prevent foreign extremist influence, so technically the government could claim its actions in Xinjiang are "protecting normal religious activities". The statement that "religious affairs are not subject to any foreign domination" could allow it to argue that it's free to define Islam however it sees fit, such that it could claim things like Ramedan are artifacts of foreign domination.

Note that the government is not arbitrarily oppressing muslims; the muslim Hui minority are not being locked up, as they haven't been pressing for independence. The Chinese government doesn't care about religion, what it cares about is stopping anyone who tries to resist it, such as separatists, and the separatists in Xinjiang just happen to be muslims, and the government sees their religion as a motivating factor behind their separatism.

Of course, this doesn't make it any more acceptable, I'm just pointing out that the Constitution as written gives the government a lot of leeway to do such things without technically breaching it.

Another line:

"Article 51. Non-infringement of rights

Citizens of the People's Republic of China, in exercising their freedoms and rights, may not infringe upon the interests of the state, of society or of the collective, or upon the lawful freedoms and rights of other citizens."

So the government could justify pretty much anything in the name of not allowing people to "infringe upon the interests of the state".
The rule is very simple - it applies to any flight originating in the United States.

Several payment gateways offer a fully hosted payment form or cart. It can be as simple as "fill in the form to set a price, and you get a magic link you can put on your website." You need no server-side code because the customer transitions to the gateway's site to pay.
I always thought it was because that space in “Program Files” was troublesome for a lot of programs, particularly command-line ones. IIRC, older versions of MinGW for instance would simply not work at all if installed in a path containing a space, because some of their startup scripts didn’t properly quote all parts of the path.
PayPal owns Braintree (and, relatedly, also Venmo).

If it's not peer reviewed, it's not rigorous. If it's not rigorous, it's bound to publish much more misleading or outright wrong content. Couple it with the possibility of ideological motivation (come on, who are we kidding?), and no... we should not welcome this. It's a net negative for progress.

Does science have the tools to "stand up to" it? Yes. Will society? No way.
It's not just about the sum. The upper and lower indices are semantically crucial. Eg: vectors have upper indices and gradients have lower indices. It's nonsensical to add the two, so the core step in gradient descent doesn't make sense. To add the two, you need the metric (Hessian) to raise the index of the gradient. And just like that, voila, you've discovered natural gradients!
The further from the coal face someone is, the harder their job will generally be to quantify and so the more likely they are to be able to slide by.
This video is notable for a couple of reasons. First, it was produced by Walt Disney. Second, it features a prominent Nazi scientist.

That scientist, von Braun, was the principle designer behind the Nazi's rocket program. He was relieved of his duties in the US space program when he started saying that man couldn't reach the moon in one jump using the style of rockets he had invented, the Saturn type which was the basis of all the Apollo missions.

Interesting.
Not to mention that this is a solved problem with the "at" and friends commands.
Your lawyer was wrong, then. If you look around, you'll find coverage of people successfully doing their startup shares in their Roth IRA, and I know one billionaire personally who did that.

Is that true? I'd like to see some statistics. I've known many people who have 'accessed' state courts (like Hogan did, btw). It doesn't cost much to file a lawsuit. It all depends on the state, of course. Plus, there's no way that Hogan was a single-digit millionaire.
> ...when you have no idea whether that's true

If you're familiar with soy milk and almond milk, it's a pretty dubious claim. The most well known brand in the US is Silk, which contains no such whitening ingredients that I have seen (see https://silk.com/products for ingredient information) nor have I encountered any other brands that contain whitening ingredients.

I think it's justifiable to say that claim is a falsehood.
You're never going to be able to stop developers dumping their shit in ~/. The best you can do is create your own directory like ~/Data to put your stuff in. Since programs don't already know about it, it will stay clean.
Folk like Alex Russell has a weird an intense hatred of how people actually use JavaScript. Of course he dresses it up as caring about user experience, but - surprise - every single time the solution to a problem turns out to be "don't write React/Angular", which is not a very pragmatic stance.

This wouldn't be such a problem, except he has a huge sway on the language via TC39 and the web via his work at Google, and keeps trying to foist over-designed complex solutions, like Web Components and PWAs onto developers.
No kidding. Seattle should be an example of how not to plan a city. Traffic is astonishingly bad given the population.
This is completely absurd and should be grounds for a GDPR complaint for any EU friends.

Are doctors doing anything to end the requirement that patients get prescriptions for drugs? What are you doing to change the system? The AMA lobbies congress to keep it broken in the favor of doctors and detriment of patients.

Doctors control our right to live. It's contrary to life, liberty, and the pursuit of happiness, because we must get your permission to live.
This is great, why is this thread so negative? Doesn't anyone here want to go and do business in China? The previous setup led to so many scams and ripoffs. Get in now before they ban it bc Chinese people will attribute foreign owned companies as having better quality.
Coffee is the main place I've experienced it, really dislike the texture vs other milk alternatives. Almond milk I think is actively better than milk in some scenarios (matcha lattes)
> Chrome, which is apparently already big on these size limits, doesn't do this

Not sure what you mean, Chrome's background tabs are heavily throttled. Killing completely after a day or two would be nice. I use an extension for that.

I think you're missing the goal when you say what "most of us care about", though. Background tabs aren't an issue for people without many tabs open (many people) or who are on mobile (even more). Slow loading pages definitely are.
> What I know I care a lot about is when a tab I haven't looked at in three days is suddenly using CPU time _at all_. Just make it so background tabs get severely limited in their ability to do background execution and eventually get stopped entirely, and the problem is essentially solved.

Chrome does throttle background tabs: https://developers.google.com/web/updates/2017/03/background...

It doesn't throttle them all the way to zero, though. If they did that they'd break things like sites that change their favicon to signal "unread message".

(Disclosure: I work at Google, though not on Chrome)
> Per-script max size: 50kB

> Total script budget: 500kB

This limit would break, nearly, all modern SAP apps. Bootstrap 4 min js bundle is 49Kb. Also, the other limits are far from reasonable.

I would be wiser if Chrome/Firefox/etc would target ad networks. Would be nice to have optimised ad that would be a tiny fraction of the website. Some ads download several megabytes just to show video gifs. These are the bastards that waste a good chunk of my 4G data plan.

Websites need to start to be reasonable about the amount of ads per page. When I pause my ad blocker, I get scared by the websites I usually visit: So many god damn ads everywhere, makes wonder why ads blockers users are not 99% instead of the current 30%.

For website owners: if your website/app is slow, users will stop using it and other websites will replace it. It's your own problem, not the community problem.

Don't think it's fair to limit javascript/browser because some morons code garbage without caring about it. It is more than possible to code fast javascript apps.
Ask HN: Should I ruin my credit score?
This account is a throwaway account for obvious reasons. First of all, I am not a U.S. citizen or U.S. permanent resident, but I used credit cards that I applied in U.S. to finance my startup for about a year. The debt is around $20000. Now, I am in an Asian country, working for a startup. I won't come back to U.S. for at least 4 years. And if I come back, it's gonna be about my new startup for sure. So my question is, if I don't care about credit ratings, should I ruin my credit score by not paying back the debt(I'm ready to pay pennies for the dollar after a charge-off, and I understand that after 7 years I could rebuild my credits.)? Thanks for your advice in advance.
Yeah Bangkok has two airports: Suvarnabhumi (BKK) and Don Muang (DMK). BKK is the airport you land at if you are going to Thailand from Europe or North America, etc. (but not necessarily Asia). DMK is the old international airport that mostly serves domestic flights and a small set of international flights to Singapore, Cambodia, Vietnam. Air Asia only has flights at DMK so when they list Bangkok they are correct.
"Article 51. Non-infringement of rights

Citizens of the People's Republic of China, in exercising their freedoms and rights, may not infringe upon the interests of the state, of society or of the collective, or upon the lawful freedoms and rights of other citizens."

So the constitution, even if followed perfectly, technically only guarantees such rights when they don't interfere with the interests of the state.
I'm not sure RenTech and Virtu are comparable though (although I'll admit I don't work in the industry, so correct me if I'm wrong), but based on the article from Matt Levine on his Bloomberg column "Why Do High Frequency Traders Never Lose Money?" [1]:

> Imagine how suspicious it would be if, for instance, your local supermarket made money on every carton of milk that it sold. That just seems too good to be true, doesn't it? How can they know the price of milk before you do? Shouldn't they be losing money on half of their milk, and making it on the other half, so that things balance out? Doesn't the fact that they always make money suggest that they're ripping you off? [...] That is, Virtu (like Goldman) is selling a product, and that product is liquidity, and it charges for that product. High-frequency trading firms are in the business of acting as middlemen, providing a valuable service by letting buyers and sellers trade as soon as they want to, rather than waiting for fundamental sellers/buyers to come in on the other side of the market.

As I understand it, RenTech is taking an investment position which is why the returns are remarkable whereas virtu is (as Levine puts it), selling liquidity.
