Last time I was in France, there is not that many NFC terminals yet. Also both of my french cards don't support it

Also 20€ limit is fairly deal breaker, doing groceries will often be above that. Even a 2 person MacDonalds is probably something like 22€

Meanwhile even vending machines can scan your QR code in China

> No - empathy just means feeling the same emotion as people around you, which is not always helpful. What you want is compassion.

That's a particularly narrow definition of empathy, most definitions include something like the following:

"the ability to understand and share the feelings of another." [1]

The capacity for this is what helps - it makes it easier to understand how the other person is feeling.

As opposed to compassion:

"sympathetic pity and concern for the sufferings or misfortunes of others." [2]

Empathy is a more general understanding of emotional state - I don't think it's being incorrectly used.

> Internal promotion, both in compensation and position, seems to be the relative norm.

My experience and observation suggests exactly the opposite. ¯\_(ツ)_/¯
I had heard of WeChat and AliPay but didn't know how it worked.
It is quite similar to what Walmart does with their Walmart Pay https://www.walmart.com/cp/walmart-pay/3205993 and what a number of retailers tried to do with CurrenctC https://en.wikipedia.org/wiki/Merchant_Customer_Exchange

CurrentctC never made it out of test marketing and I don't think Walmart Pay is taking off.

The difference is that these two are from big retailers and the Chinese versions are from apps or online retailers.

How do you account for all the people who did subscribe to it at some point in the past, but no longer do?

Case in point: I used to be an ancap. I've read "Atlas Shrugged" many times, and I worshiped Rothbard.

That was many years ago. In this past election, I supported Sanders.
They actually do.

Well not _you_ but bills do get flagged if they're involved in crimes (like kidnapping or robbery). So when they're deposited in a bank the FBI can track the _relative_ location of criminals.
Interesting, looking at the price graph Ethereum's price seems to correlate with Bitcoin's, which lost about %20 of value ($500) recently. In case anyone's wondering, the crash seems mainly driven by anxiety of an upcoming blockchain fork splitting the currency in two next month.

That doesn't make sense; you are comparing the creation of a currency against the usage of other. The finance sector includes the creation of cash (its paper, price of counterfeit measures); the transportation of cash (think ATMs), the materials needed for creating debit and credit cards, including their chips, the equipment to protect banks from being robbed (think big steel security safes) along many other resources to make such industry work.
Germany also doesn't really take credit cards.

Well, didn't.

The EU limited fees for credit cards to 0.125% recently, and while EC (now bought by MasterCard and called Maestro for SEPA) is still cheaper, credit cards start being affordable for merchants. But almost none support it yet.

And Google still hasn't launched Android Pay, despite every ALDI having NFC. I'd prefer if there was a local NFC payment option actually.

China has Unionpay. Because merchants don't often have terminals, and because paying with phones is more convenient, people just link their card to WeChat/Alipay and pay with the apps
>most empiricists believe that mathematicians have knowledge not based on sense experience.

Even the knowledge that 1+1=2 comes from sensing objects in the world. If you'd never seen more than 1 thing ever you would have no sense experience to base your conceptual framework of addition on.

All knowledge -mathematical or otherwise- can be traced back to sense experience. Your ability to reason mathematically comes from your experience of the world and from your experience of your own thoughts. Intuition is fundamentally a sensory experience.
Living in China for the past two years -
Important thing to remember - in China and in most of South-East Asia the tech boom came at a later stage when smartphones were already prominent. Android + Chinese manufacturing made it possible to produce cheap smart phones. The result is that these countries have completely skipped the laptop phase and went straight to smartphones, most of the population doesn't even know what a laptop is.
What the west calls eCommerce (amazon, Ebay etc) is called mCommerce in Asia (Taobao app, JD.com App etc). Asian consumers find it easier and more natural to shop using smartphones rather than laptops like Western consumers.

Oh and yes, When I leave the house I don't even take my wallet, everything is paid using wechat.
Take the credit card swipe versus chip example. The chip is an improvement over the really old swipe tech in theory. In the US, using the chip is a terrible experience because it takes a lot longer for the process to complete. Why? Because merchant processors have no interest in putting the chips on a fast network because they can get higher fees on the swipe and conversely the stores are charged higher fees for enabling the chip. There you go. There's the moral question and the profit question all in a real example that didn't improve the experience for the end user.

And of course, there's the "buy a full set of interchangeable socks" approach. I did this a few years ago and it's great. Pairing socks seems trivial but saving 10-20 minutes a week, every week, for minimal investment (I needed socks anyway) is a huge win.

One caveat, though - if you do this, commit to it. Don't do what I did and keep one or two pairs of non-conforming socks just because I liked them. Because now they just recirculate through my sock drawer, gumming up my otherwise perfect system. :P

Everyone in Australia just uses paypass/paywave contactless payment with their credit cards. I rarely carry any signifiant amount of crash for that reason. It's essentially the same as using your phone except you use your credit card and doesn't require a PIN or anything for <$100. Once I have a transaction over $100 I can tap and enter my pin, or use chip and PIN, or if everything fails occasionally I need to swipe and PIN. Most critically, signature is no longer allowed.

Without having used WeChat's approach with QR code scanning, it doesn't seem that different for the end user in practice. Either way, you're scanning an object you carry against some target environment and a merchant is processing the transaction for you. It's even closer once you use eg: Apple Pay with your CCs loaded into the Apple system - you're tapping your phone rather than scanning via the camera.

I'm guessing that the CC infrastructure simply wasn't there and pushing out EFTPOS units was a far higher barrier to entry than simply running an app on your newly acquired cheap chinese smartphone. As such, the CC merchants missed the boat whereas the big phone app companies got in on the ground floor. On the flipside, many Western countries had all the EFTPOS terminals already, so contactless just became the next iteration on that.

I don't really necessarily agree with the problem of the country building their commerce systems around Tencent, etc. as 'private companies' since most of the west hinges on Visa, Mastercard and to a lesser extent Amex. They're all private companies too. Maybe the government will step in and standardise the QR code system eventually to reduce the risk. I don't really see it playing out much differently to how the West did with CC contactless.
Where I see the cashless innovation failing deliver is where there is a state-owned enterprise providing a service. I was in Shenzhen on the weekend and had to use cash to pay for a one-time use token to catch the subway. Lining up to pay took a good 20 minutes by itself.

The Shenzhen subway seems like an exact copy of Hong Kong's MTR, which uses the excellent and ubiquitous Octopus system. The MTR is its own entity and allowed to play favourites (or enable monopolistic behaviour).
I'm a Chinese & living China, I shopping almost only with credit cards and cash for privacy consideration.

However, I don't think credit cards in China are as popular as it is in the USA. I could guess most Chinese people don't have any credit card.

Chinese traditional culture encourages saving, not loaning. And taking small loans is exactly how credit cards works. So maybe that's why people here don't like credit card very much.

QR pay (Or mobile pay, OR more specifically, Alipay and Tenpay etc) can acting like a gate way between seller, user and bank. It can pay with the money you already have, no need to loan from the bank. So I think it's a Culture Match.

Beside that, take a wallet (Which is needed for protecting your credit cards from been scratched) everyday is a burden. I could really be happier if I can get rid of it from my EDC (I can't get rid of my phone, so).

> A mile of diameter weights 7 * 10^8 * density_of_the_asteroid kilograms

This sentence, in so far as it can be understood in English, makes a wrong assertion. Only the first mile of diameter approximates to that; "the" mile, not "a" mile. In the context of the conversation - long lost in this subthread - it's the wrong answer without further clarification. It was in reply to the question "How much does a mile weigh?" - again, note "a", not any specific mile. Someone who takes the reply as an answer to that question would be even more misled, irrespective of how well rimliu understands the problem.

To be really specific: I think 90+% of people would think that an asteroid with a diameter of two miles would weigh 14e8 * density, given this answer - and they'd be wrong, and increasingly wrong the larger and larger an asteroid they're calculating for. Because mathematical intuition is not common.

I added the clarification. Then you came in with your intervention, for reasons that aren't yet clear to me.
Contactless payment systems are prevalent in Australia. And even before tap to pay we were able to insert cards, enter a PIN and pay. What has happened in China is that they payment systems have been baked into the apps where, in Australia, this occurs at the terminal (EFTPOS as an example) which is app agnostic and tied directly back to the bank gatewys.
> the transaction fee, for many, is perceived as a rip off

Only if you're a merchant. Most of the 2-3% fee is transferred to consumers via reward programs. It's important to understand that merchants and consumers face different incentives and that US card networks have aligned themselves with consumers.

It's a symptom of how hot the job market is, IMO. The traditional view is that employees had to compete to get regular raises and stay employed. It's flipped a bit, and now there's more effort that employers have to make to keep high-value employees from leaving for better pastures.

Someone who job hopped five times in ten years has convinced five different employers to give them a significant pay raise to poach them. Someone with one job in ten years is likely in the "I'm just lucky to be employed" category and is less of a hotshot.

Dang I respect your work a whole lot and appreciate all that you put in to keep HN a place i like coming back to. But the comment above was totally unwarranted and uncalled for in my opinion. I flagged it (of course, just as a token symbolism).

Promoting self censorship just because a topic is unpopular is not a theme that I associate HN with. Flame war aside I am happy that some sane discussion and information around the topic came to light because of the comment that started this.
Not only that in the context of story and the current time I did not find it off topic at all.
I'm curious, how much more do you think you could get by leaving, or if you had been job hopping? Companies say they value loyalty, but that can seem fake if loyalty ends up costing the employee money.
I don't understand people's obsession with happiness. It always seemed like a very weird and arbitrary metric. Orgasms makes people happy, perhaps we, as species should come together and fund/help build the constant orgasm machine, we will all be very happy.

> And what's stopping me from setting the constant to something lower in my own mining code?

The difficulty constant is determined by an algorithm that takes into account the average time that it currently takes for a new block to be mined. It tries to balance difficulty so one block is mined every 10 minutes, on average (if blocks are being mined too fast the difficulty increases, if blocks are taking too long to mine it decreases). This algorithm is part of the "bitcoin protocol" and you can't just change it in your own mining code because the other nodes in the network will not recognize your blocks as valid if you use the wrong difficulty constant

> Does it follow that if most people in the network are duped into a ridiculously high difficulty, that it will be impossible to mine more BTC?

This is kind of what has already happened. Nowadays there is specialized bitcoin mining hardware out there which is has driven the difficulty into the stratosphere. Bitcoin mining using CPUs and GPUs has become unprofitable, which is why the small miners have moved on to alternative cryptocurrencies where they won't need to compete with specialized hardware.
Is there any value to the code in failed attempts or do you just want a log of things you have tried?

If the former, you could try a single experiment branch and use tags to denote different experiments. Add a tag when you finish an experiment then overwrite with your changes for next experiment and repeat. This would keep all the changes while not have having a huge number of dead branches and the branch could be merged when necessary.

If the latter, why not an experiment log that is checked in which has a similar form to a change log? Or maybe create an issue and branch for each experiment then update the issue with results and delete the branch?

No, rewriting all of that Lisp code would be impossible. It's also unnecessary. The primary advantage of Rust is safety; the compiler ensures that either your code follows the rules or that it doesn't compile at all. The Lisp code, on the other hand, already has that safety. No manipulation of conses or vectors or other lisp data structures will ever result in a buffer overflow, or a null-pointer dereference, or in doubly-freed memory, or any of a hundred other of C's pitfalls. On top of that, Lisp is extremely fast to write, test, and debug.

But of course, that safety only exists to the extent that the Lisp interpreter/compiler is bug-free. The C side of Emacs's code base is alternatively great and terrible, depending on how you look at it. On the one hand, 30 years of continuous development has resulted in code that works really well. On the other hand, it is very hard to extend this code to support new features (good multi-threading support has been in the works for ages, moving to lexical scoping and away from dynamic scoping has taken years, etc). This is because it's difficult to maintain quality and compatibility while also navigating such an old project.

Once enough of this old C code is rewritten in Rust, it'll be possible to leverage the memory safety features (and the type system) of Rust to innovate much more quickly. Not as quickly as you can innovate on code that's written in Lisp, but much more quickly than you can innovate on the C code.

Besides, the number of libraries that a program uses is only a detriment if it means that the developers have to spend more time installing and maintaining those libraries. Cargo makes this comparatively painless.
As an avid emacs user... I would never use this.
I recently took a trip to Shanghai and Kyoto and was blown away by this. In Shanghai even the taxis displayed their QR to accept payments. Kyoto accepted WePay and AliPay; the latter was most impressive because I was told AliPay requires the Chinese equivalent of a SSN

After the first year of the reboot, with that Eggles-can't-spell-it guy, I couldn't keep watching the reboot. Same formula over and over, each episode: Doctor to the rescue! Skin of the teeth!

I enjoyed the first year of the reboot. The Doctor/Rose dynamic was something new and really well played.

I'm no longer a regular watcher, but I guess I did note a few exceptions to the above. E.g. particularly the episode where... Tenant, I think, encounters a forward-thinking female member of the royalty. Good writing and chemistry in that one. Ok, and Donna was a good change-up at points, another different bent to the companion role.

I guess I mostly wish the episode stories weren't so basically repetitive. For the most part.

But then, there was the... um (sorry, not a remember the name of every detail kind of fan) "stone angel" episode, with a younger Carry Mulligan. Unique for being an entire episode with the Doctor at best making a cameo at one or both ends (just the end, IIRC). That was different. And, Mulligan did a great job.

At that time, I thought she would make an excellent Doctor. Hoped, wished production might think of the same thing.

Didn't happen. But now, here we finally have a woman in the role. I hope it adds some new aspects to characterization and the roles. I hope, too, that in might inject some new thinking and variations into the writing and story construction and focus.

As for production values, Baker remains my favorite Doctor. Yeah, the sets were obviously sets, and some -- many -- of the aliens would have been at home in the Los Isoles (sorry, again, not the kind of fan who knows the spelling of that) bar back in the first Star Wars film, "A New Hope".

But the characters were characters, and they showed more than a bit of heart. And, where I was, then, the syndicated broadcasts made for a great excuse to stay up too late on Sunday nights.

Some more of that, please, Ms. Doctor.
Does success in work bring you happiness?

Yes. More than anything else.

It's not the money part. I don't make much. It's the influence and seeing my work actually shift how people act and live their lives - especially seeing where it will lead.

I have three kids and when I talk with other parents, they say that they get the most joy out of seeing how they can positively influence their kids.

What about positively influencing millions of people, consistently over the long run with your work? You do that through impactful, meaningful work. Maybe it's software or maybe it's building houses, or providing access to capital for low income people, or working on vaccines, or any number of the millions of things that influence people at scale. That's the difference, at scale.

You can't do scale with personal relationships, you do it with work. Define work however you like (charity etc... it's how you spend your time)

How could that not be the key to happiness?
"Android was released a couple years after the iphone "

This is a really interesting history rewrite, since it was released a year and 3 months later.

It also didn't define the low end of the market, since at that point, the iphone was just getting apps (2 months earlier is when the apple app store was released)!
There _is_ a major disconnect! You’re studying computer science and wondering how it applies to software engineering. When I studied CS (graduated a year ago) we never went over things like building a GUI, reverse engineering an API, or designing a UI. Those are software engineering topics. By the time I graduated I learned how to do those things, but it was by learning them on my own. If you want to learn these things you’ll need to take the initiative yourself.
