Having worked in ecommerce ~8 years ago, one reason I'd say is simply order history. Order table linked to the same address table as the users address book.

If you actually delete the row, the seller would lose the address the order was delivered to. They can need that for any number of reasons including legal compliances such as sales tax compliance.
Phoenix(Designed by IBM) to take 5 years, billions to fix: report
I like the idea of a system that would allow only 2 coins - .5 and .1 - to function properly. However it could potentially mean removing the quarter from circulation completely, unless the holder is willing to sacrifice 20% of its value or has two of them.
I quit using Waze for exactly that reason, after being a happy user for years. I wonder who thought it would be a great idea to have me make an unprotected left turn from a side street onto a major road with no signal at rush hour.

Suggesting caution is not automatically saying everyone who didn't take that advice derserves what happened to them. Saying "you should wear your seatbelt" is not the same as "you deserve to get maimed or killed if you don't wear your seatbelt". Similarly, saying "don't put identifiable info on forums" is not the same as saying "if you put PII on a public forum you deserve to get stalked".
Wait, obviously not everyone in your life is losing $2300 at a casino regularly right? So to them a few dollars might be important?

Hacker News reading can be an especially pernicious and problematic addiction. Seriously, often in the startup world I find software engineers with TODO lists spanning space and time compulsively reading and scanning the HN front page. Oh, look: cannabis users addicted, dopamine rush. Altruistic punishment means an immediate boost to social status and opportunities for bonding. So who exactly is addicted to what again?
We still have no idea how to eliminate more than a quarter of energy emissions
The linked article is already taken down, but from the perspective of a woman, I will add a few thoughts. I attended a rural university that also shared a town with a state penitentiary. Periodically over my years there, the university would put notes in student mailboxes informing us "The state prison was releasing on parole convict X on [insert date]. X was tried and found guilty of 3 counts rape. X stalks women and was armed during each of the events for which he was convicted. Psychologist have stated that X has near 100% likelihood of reoffending. If you are female do not walk alone. At night, do not walk without campus security or in small groups." The times we got a note like this, some weeks or a few months would pass, X would reoffend, raping some woman who normally did not have the benefit of campus security escorts, and we would get another note in the mailbox telling us that the security recommendation was no longer in effect. The town police were hard men.

Last year in college, a neighbor came to my door freaked out because somebody was peeping on her. Called the local police.

Police officers came to our door told us that peeping toms and flashers had statistical likelihood of escalating their behavior to more and more extreme acts including rape. They already knew the guy based on the neighbor's description. Also said not to fuck around if we saw him again. Any indication of a fixation was a really bad sign.

So should submitter be subject to legal scrutiny, monitoring, and restraint on behavior after that single event? Absolutely. Bad behavior for some, begets worse behavior later. Should submitter be subject to scrutiny, monitoring, and restraint decades after a single offense? Probably not.

We have sexual predator laws for a damn good reason: some people are guaranteed to violently reoffend unless prevented from doing so. Use of those same laws to ensnare teenagers who sext, Romeo & Juliet lovers, and the legitimate one-time offenders, is outside the original law's intent. The issue for the last category of offender is having a legal path to redemption. This piece seems to be missing. Arguable that for a lot of ex-convicts, a path to redemption and unrestrained participation in society is missing.
It’s also the extent of the anarchy-libertarian stance popular on HN.
None of this makes it physically addictive, which is the only issue I'm making. Mental addiction can also be terrible, and can cause the issues described.
Is there a place, like Groklaw's UNIX timeline, where you can see which software is derived from what?
All addiction issues are just the surface of an underlying problem.

The problem is that there are a lot of situations in which tax is exempt and/or variable depending on the customer.

i.e. Joe Sixpack is going to pay 7% on his loaf of bread, but Jane Wicstamps buying the same loaf of bread with food stamps does not get charged any tax.

Additionally, some municipalities will do things like say there's a general 7% sales tax on everything, except groceries, which are taxed at 2%...until next year, when the general tax goes up to 8% and the tag on literally every item in the store needs to have the price adjusted.
Nothing is stopping you from having the computer back-calculate the tax and display it on the receipt. I seem to recall the ones I got on my last European trip showed the VAT as a separate line item despite the price tag including the VAT. I mean, isn't that the whole point of having an electronic POS.
> Think about it for a second: there is someone buying and selling, consistently at known price points.

This happens all the time in the stock market. Look at the SPY stock which tracks the S&P 500 index. At everypoint in time, anyone can compute exactly what value this stock should have. Any deviation from this consistent and known price point is immediately traded away by arbitrators.
This is one of the best terrible ideas I've ever heard.
I think part of the issue among users is that "rely[ing] on Google" was (and probably still is) a perfectly acceptable approach that already worked reasonably well until Apple inexplicably replaced it with Maps.
> why browsers can still stop fingerprinting (emphasis mine)

> privacy defenses don’t need to be perfect. Many researchers and engineers think about privacy in all-or-nothing terms

So browsers can't stop fingerprinting but they can reduce it, and the article author's title falls in the same all-or-nothing trap that they criticize others for. Too often practicality is viewed as defeatism. I don't remember defeatism, I remember practical limitations to stopping all uniqueness vectors but realization that some can be stopped.
Dropping the average number means that trackers make less money which means that they have less resources to invest in tracking which means that there's less of a chance that you specifically will be tracked.
Coins: the busy work of business, that's why they mostly switched to credit cards, for similar logic you're using regarding pennies.

Stores don't typically raise their unit prices when they decide to accept credit cards; they benefit from efficiency (and lack of theft) and receive more volume in sales as a result.
Social Media Checks are becoming more popular
Scientifically speaking, no. A scientific hypothesis must be falsifiable, and to be falsifiable it must be testable. I guess in some sense you could claim that there are hypothesis that are testable, but which we do not have the capacity to test. But then, is the claim that "one day in the future, we will be able to test this other claim" itself falsifiable? I'd argue not (it's a recognizable, not decidable claim, in the computational sense, and I think that for a claim to be falsifiable, it must be decidable).
Apple has a team right now working on OSM: https://github.com/osmlab/appledata/issues

The article just strikes me as plain wrong in this regard. Yes, of course Apple isn't going to use OSM in the Bay Area, but it's a big world out there.
I must have missed the part where Google is letting state run Chinese companies run their data centers and sharing the data with the Chinese government. When that happens then Apple and Google will be on equal footing when it comes to China.

>If you have issues with China's human rights, you should encourage your local government to take up that issue. Your post reads like a bunch of raw emotion and statements like "Tim Cook doesn't believe" that which are just impossible for anyone BUT Tim Cook to know. Relying upon supposition of what you think a person thinks, and extending that to a company to arrive at a conclusion of: money > human rights is... pretty sad as arguments go.

What's really sad is that Apple's revenue from China is far too lucrative for Tim Cook to really care about human rights and privacy. Tim Cook knows he'd probably be ousted as CEO if he ever tried to exit China.

Hi Scott,

This may be an ill-formed question, but it's something I've been thinking about for a long time:

Do you think the human mind is equivalent to Turing machines, or somehow above it? Assuming we have an infinite tape/memory and time.
> Are there things that we can't test that do exist?

Lots of people think so (e.g. unmeasurable things predicted by theory like parallel universes, but also things like evil or God or the color purple), but by definition it's hard to be very sure, or to transfer your own confidence in such things to others.

Lots of these kinds of questions reduce to quibbling about definitons; and also by definition, if we can't test the thing then the universe isn't going to punish us either way for believing or not.
Interesting. That's way more physics than I know. :)

General management lessons from Larry Weed
Google's estimates seem most accurate for me if I can consistently break the speed limit by about 15 mph. If I get into a bit of congestion and get stuck at the speed limit then it misses the mark.
So I originally wrote this post to respond to the user "havesmoked" who posted a similar comment in response to you to what I'm about to share. They deleted their post, but I figured I'd still post mine.

----

I also don't know why I'm posting this beyond sharing my anecdotal experience, lol.

I'm pretty much like you on this one. I've been smoking pot for about ten years now (I'm 31), and half of that I'd say has been fairly heavy usage, and for the last 2-3 years a single week for me has, on average, seen me consume: 1 eighth of flower, 50-100MG of edibles depending on weekend activities, and most of a .5G vape cartridge. That seems like a fucking outrageous amount of pot, but I've shown continuous growth professionally (worked all the way up to my current "Director" position) and I've never had a problem traveling and suddenly spending a week or two cold turkey.

Like you, I've always been cognizant of the fact that I could end up relying on it as a crutch, and have been wary of the fact that there's not much quality scientific data around marijuana to make me feel comfortable continuing this way. My wife and I are also at a point in our lives now where we'd like to start having children. We met with a doctor last week to discuss a few things, and the "marijuana lowers your sperm count" conversation that I was anticipating did certainly come up. I've known this time has been coming for a while and had no problem immediately cutting back as of last Thursday. It's been just over a week now of reducing my intake to just 4-5 hits per evening, late at night and shortly before bed so I don't get the urge to just keep smoking after I've started.

It's been incredibly easy to kick, I'm gonna save a boatload of cash, and I don't spend the day craving it. I appreciate the clearer head that I have, and the increased productivity I feel. But that doesn't mean it's easy for everyone, as I'm sure people use this as a crutch for a variety of reasons.

Edit: I think one of the things that has helped me keep my consumption reduced compared to other people in this thread (someone mentioning nearly an eight per day) has been my refusal to do dabs. Those are incredibly more potent and can really quickly kick your tolerance up a notch. I did one just once and it hit me so hard I immediately fell back and had to lean in place against a wall without moving for 20 minutes. I don't know how people can do that shit regularly.

I am not defending Apple. My point is that no corporation an (or should) is above the law. If the law is problematic, it should be fixed. But no one can be allowed to go against it.

Let’s say Apple leaves China. So what next? Do you have any contingencies outlined where the people of China get their rights?

And by the way, it’s not about Cook. Decisions like these are made by the board with shareholders’ agreement. I recommend you learn how things work before you go bashing.
I told this to my girlfriend and explained to her what tau is. She responded that she actually had bought two pies just a few hours ago. Excellent.

What’s popular in the tech community is some combination of laziness and naive political cynicism masking as strategy or anarcho-libertarianism.

Yeah, and it looks like the process has already started:

They said it was the solution to keeping cool indoors. I don't know how you read "keeping cool indoors" as "climate change", but the two aren't the same thing.
You don’t seem to know what it does. When did you last look at it?
The platform looks interesting, but the fact that you're offering an ICO makes me immediately wary of your company.
While the title says we have 'no idea' how to do these, most of the items listed do have viable but expensive solutions (ie carbon recapture, energy storage, etc).
The UK is usually very humid too when it's hot so the heat index (the 'feels like' temperature) is much higher. For example 30°C could 'feel like' 38°C if the humidity is at 80%. Also terrible if you are sweating and it can't evaporate.
Most people in the country live in cities though, so it's not really unreasonable to be surprised that some people never encounter the extremely destitute. Maybe it is you who should leave your bubble of wealthy suburbanites?
I'm pretty sure that would lead to a near absolute zero survivability for anyone on board a system like that.
What infrastructure do you think they don’t have?
Agree, Apple should just commoditized maps with a big open source initiative to take the leverage/power away from Google. They just need a highly functional solution for their platform.
It is worth mentioning that the mentally ill are (sadly) fairly common in this society. Historically mentally ill people have not tended to be more dangerous than average people and it important not to assume that mentally equals dangerous today.

That said, I think, historically, a substantially part of the reason mentally people usually are harmless is because they can see their grasp on reality is shaky. Others have generally not shared their delusions and so no one validates their desires to lash out at those who they imagine have harmed them.

The Internet seems to have changed that - communities of people who share pathological illusions seem to have come together and produced a still small number of horrendous crimes - the "incel movement" being one very visible example.

These folks might well in dangerous (to others) gray area between debilitating insanity and approximate sanity. Pathological enough to embrace problematic ideas and functional enough act on them.
Head of Product opening at OneSignal
Yes, I do think there's a significant chance of that. If it happens, my main interest would be to understand WHY. What are the non-obvious limitations that you mention? What is true about the world that makes it seem to have this exponential explosion of amplitudes, yet makes it impossible or infeasible to harness them for computation?

The depressing possibility, of course, is that we never succeed in building useful QCs, but we also never learn anything deep about why we failed: it was just too complicated, too messy, and then at some point the funding ran out.

But I like to proceed on the assumption that the world is ultimately comprehensible (what other choice does one have in science? :-) ). On that assumption, if QC can never work, then there must be a deep reason that's not articulated in any of the existing physics books: either a breakdown of quantum mechanics itself, or else some new principle on top of QM that "screens off" or "censors" QC. Needless to say, the discovery of that principle would itself be a revolution in science -- indeed, I'd personally be more excited about it than a "mere success" in building scalable QC! (But my own bet is on the "boring, conservative" possibility, that QC can ultimately work.)

If we see the milestone of "quantum supremacy" achieved in the next few years -- i.e., a 50-70 qubit quantum computer used to solve some artificial sampling task many orders of magnitude faster than we know how to solve it classically -- that will obviously be one strong indicator that the potential of QC can be realized. An even better indicator would be the use of a quantum error-correcting code, like the Kitaev surface code, to keep encoded qubits alive for longer than the underlying physical qubits are staying alive for (or better still, to perform 1- and 2-qubit gates on them).
The USA is terrible. Don't come here.
Many people underestimate the total costs of commuting. They want a cheaper and/or bigger residence. They think they're a superior driver and/or they'll buy a bigger car for safety. They would never take a salary cut even if it came with a greatly shortened commute. Car operation cost deltas are not included when considering a job or residence.
Well now you've gotten me all bothered, too. And if I do manage to find the street name but can't quite read it because the font is too small, I zoom in and the road expands but the font doesn't. No matter how I zoom or pan, it offers either 1) too small, or 2) oops, I disappeared again.

> A scientific hypothesis must be falsifiable

This is certainly one understanding about what science should be (although not a scientific one interestingly enough). Personally I prefer Thomas Kuhn's demarcation, which by my understanding concentrates more on whether a scientific program is producing interesting predictions which turn out to be true.
It doesn't help much to deploy this to routers, since they aren't endpoints for much TCP traffic volume. Smartphones, laptops and other Linux-based client devices are what need this fix the most.
I resisted for a long time, but when I got my newest car it came with CarPlay and so I started using Apple Maps because I had no alternative. Now I see that iOS 12 is going to relax that restriction ... and I am going to stay with Apple Maps. Works fine for me, and nice to know Apple is not tracking my every move.
Figured I'd drop this link here. This is a neat pathway, that scientists in different camps have focused on over the years but haven't necessarily tied to aging biology.

What I find fascinating is that it appears viruses have evolved to exploit our own immune systems against us, and this very exploit underlies heart disease, dementia, and even some cancers.

The Echo Show is a horrible disappointment. I got one when they were released in the UK because it seemed the perfect thing to keep in the kitchen, but it’s crippled beyond usefulness.

My primary use case was going to be watching Netflix with voice control. Netflix has yet to appear
on the Show, and because of Amazon’s zealot like insistence that everything be driven by a voice UI there’s no web browser or app support. The thing is clearly running some version of Android, I wish they’d just bite the bullet and throw FireOS proper on there.
Surely the value of a penny to The US government is more than just the monetary value displayed on the face of the coin. The ability to store 0.01 USD has to be worth more than 0.01 USD or at least (production cost) - 0.01 USD.

Is the idea that someone will guarantee me some basket of consumer goods (or some amount of another currency which can readily be exchanged for said basket) if I give them 1 DAI?
Not worth the effort? You underestimate my cheapness at your own peril.
Then again they can offset these costs by having a much larger customer base (i.e. people without cash on them) from which to help them realize greater volume discounts.
I don't really understand this - if you need to 'keep your lambdas warm' why not just run them as a process?

There seems to be a lot of book-keeping and ritual for something which is supposed to just let you focus on the important bits of code, without worrying about how it runs.
