> The blockchain is for censorship resistance.

The blockchain is for having an immutable[1] log of transactions that does not require trust in the peer that you are making a transaction with.

Off the top of my head...

- Bank transactions

- Security audit logs

- Securities (stocks)

- Corporate governance

- Actual government

- Legitimate business transactions where you don't want to have to worry about charge backs or bounced checks

The article also falls into the trap of thinking Bitcoin and Blockchain are anonymous. They are not. Some blockchains try to be more anonymous. Bitcoin is not one of them.

[1] Yes, I know the blockchain can be forked which in theory makes transactions mutable. However, the barrier to take advantage of that is prohibitively high and highly visible (i.e. is hard to do in secret).

Even the Biggest Scandals Can’t Kill Party Loyalty – FiveThirtyEight
At that age, brain still develops and relative ordering of children still change. The lowest performers are unlikely to become best, but the middle still changes significantly. Otherwise said, it is too soon to determine how good they will be as adults and what they will be good at.

Also, at that age, your ability to learn climbs very high just as function of age.
But the government wouldn't need to pay to send a million of them. Just enough to send the people they want to send, along with associated equipment, plus the costs of feeding and housing them.

Remember, we're only talking about the portion of the mission funded by tax dollars here. Not all of the funding is going to come from that source.
Perhaps that's just the price you pay for access to ebooks at all -- particularly via an incredibly convenient system like Kindle? (Also, loaning -- the most pressing concern here -- is supported.)

Authors need to get paid. I completely understand the irritation DRM presents, but if you want to be able to resell your books or pass them down through the generations, maybe paper copies are the way to go under our present conditions.

A second question. Most of us, I presume, work in software. How do you approach the distribution of your work? Is unlimited piracy of your code an acceptable price to pay for giving customers unfettered access to the product of your labor, in your eyes?

The only way I believe that they can be modified is by literally burning them off or if you get a deep scar or cut, that can permanently alter the way they are. As far as "genetic modification" goes, likely not.
I buy BBQ from Smokey J's (https://www.smokeyjbbq.com) in Berkeley, CA with bitcoin. They have an android tablet under the counter for taking transactions, it's great!

Never bought drugs with them before, according to the artice maybe I should try...
From the article: " To be fair to the F, we are involved in an advanced discussion with Facebook about the creation of a subscription mechanic that would benefit news organizations and journalists – perhaps generating enough revenue for the industry so that journalists do not become a modern mendicant order."
So they are launching all of these frameworks targeted to mobile but what's happening to Tensorflow Lite ? I'm beginning to think that these things that they are releasing are scaffolding for this . I really hope it's not going to be vaporware from google I/O
> For now, because mass-produced starships are not a thing yet. SpaceX is on the best way to change this.

Ignoring the cost of the rockets, the biggest expense in space travel is delta-V, followed by life support. That's basic physics, and no amount of cheap rockets will help.

> I'd guess if you put in a proper emergency hospital kit on a pre-manned-flight-mission and two ER doctors on the first manned flight you're pretty much set.

Your ER doctors won't help if the habitat springs a leak.

What I meant was:

* ripped space-suit? Die.

* leak in habitat? Die

* run out of water? Die

* plants get disease? Die.

* air recyclers break? Die.

Plus, there's all the Earthly ways of dying! Fall down a hole, have a rock fall on you, etc.

> Lots of dangers that kill in short time on Earth are simply not present on Mars - you won't have deadly new pathogens, no cars, no dangerous animals and cancer can be kept at bay until a flight back to Earth can be arranged.

The same can be said for the space station... no diseases, wild animals, etc.

Why not build LEO habitats instead? Lots cheaper than going to Mars, and re-supplies are just a few hours away.
Yes, I only ever bother to go into Best Buy because I know they will price match Amazon (and their own price.)

I recently realized that even Wal Mart had lower prices for some things online, and now I have to go through the hassle of having them price match their own website when making certain purchases.
It's APIs all the way down

I think the order matters in the 3rd exercise. As in your "buy" index has to come before your "sell" index.
Incredibly common use case:

1) Hi there I have a request for a meeting or phone call, or need something from your organization.

2) Great, I'm copying my assistant who will schedule this, or the other person in the company who knows the answer to your question, who I have now handed this task off to nearly instantly and seamlessly.
when you have a scarce resource with the consensus of many people, digital or physical, it works.
There are a lot of people living near me that want to send money back to relatives in the country where they were born on a regular basis. One of the advantages that are often touted as a legitimate use of bitcoin is to lower transaction costs.

In light of that claim, I wonder how difficult it would be for: one of my neighbors in Queens, NY to take $1000 cash, turn it into bitcoin, send it to a brother in Cebu City, Pachuca, or Dhaka; for the brother to turn those bitcoins into Philippine or Mexican pesos or Bangladeshi takas; how long it would take; and finally how much it would end up costing versus the mid-market exchange rate between dollars and the other currency.

"It's Brunello Cucinelli. I know this because I worked in the store he shopped in. They are $400 t-shirts and those sweatshirts are Brunello as well and are around $3,000."

"Mark Zuckerberg wears custom made Brunello Cucinelli tees in marl grey. I believe they run long for him, thus needing a hem. He chooses to order in bulk for an estimated cost per unit that varies from $300-$400. Price reflects on an order of plain custom tees vs. one of grey tees that feature the original 3 emblem Facebook insignia on the upper left chest."

At some of the big box stores near me it doesn't even need to be intentional, they're just in a near blackout zone with my carrier. Their Wi Fi doesn't tend to perform a whole lot better though.
In addition to using Whole Foods stores as a locker location, Amazon can also ask Whole Foods employees to deliver packages on their their way home from work. Like Walmart - https://www.washingtonpost.com/news/business/wp/2017/06/01/w...

Changing the dialect is not the same as a foreign language translation. It can easily be misunderstood as the author's intent since it's the same language overall. It's copyediting something already published.

As someone who grew up in Hannibal, Missouri where Sam Clemens did, let me tell ya it's still a tad diff'rent from N'York.

If someone intends to "modernize" a book, particularly the dialog, they need to make it clear that it is a translation from one dialect of the language to another. They need to not credit the author those new words and say they just fixed typography. There needs to be an "as interpreted by", and that person needs the blame by name.
> It's extremely naive and arrogant to spend the resources to colonize Mars than try and make more places habitable on Earth.

Why?

And I'll note that insults and ad hominems don't make a rational argument.

> It's even more arrogant to believe that a Mars society will be any different or better than the society on Earth.

No one said that.

If your best arguments are insults and straw men... well, it's best to avoid a technical forum like HN where there are people trained in rationality, math, and rocket science.

This reputation is meritless these days. I work remotely from a desirable town, with, ahem, very competitive pay, 4 weeks vacation, generous RSUs, etc. It's the outdated reputation rather than the actual facts that inhibits hiring IME.

WMT is written off way too easily on these forums.

It makes more in profits per year than AMZN probably has it's entire history.

And I certainly think it's gonna be a lot harder for AMZN to replicate WMT's network of retail stores (which double up as warehouses) than it would be for WMT to replicate any of AMZN's online efforts.

In addition, by being a "retailer" WMT also avoids getting into competitive fights with the likes of Apple, Google and Microsoft, all major platform owners, and can instead better partner with them.

One can way overdo the modernization. From "The Message", a modernized Christian Bible:

"God, my shepherd! I don’t need a thing. You have bedded me down in lush meadows, you find me quiet pools to drink from. True to your word, you let me catch my breath and send me in the right direction. Even when the way goes through Death Valley, I’m not afraid when you walk at my side. Your trusty shepherd’s crook makes me feel secure."

Don't go there.
I have a job interview with Amazon next week. Wish me luck, I'll be likely doing entry level work but I hope I can keep working on websites for clients (have 2 currently), keep learning data structures/algorithms, and build a personal project. All this to one day get hired by Amazon for UX or web developer.
I come from very similar circumstances as yourself! Just moved to the city-ish area, but having land for the kids to enjoy is nice. And quiet too!
For those who have never heard of bonobos, their pants fit exceptionally well. Andy & co focused on doing one thing, having quality pants that fit really well. The fit of the clothing matters more than anything about bonobos and it is where most brands screw up.
Blockchain does not reduce the need for trust, in my opinion. If I order pizza from you and pay with Bitcoin, I still have to trust that you'll deliver the pizza. There is no way around the need for trust (though of course there are mechanisms such as laws, police, and judges that help reinforce trust in our society).

The only trust that blockchain provides is trust that a counterparty won't go back and change the ledger showing that a pizza was ordered. This solves the double spending problem, but it doesn't solve all the other kinds of fraud.

Let's make America lesser
We actually have Huck Finn in our catalog, and of course we've preserved all of the vernacular. I invite you to check it out for yourself to see what you think. "Light modernization" in our sense doesn't mean "ham-fistedly change old-timey vernacular into new-fangled internet slang", it simply means some basic, mostly-automated one-to-one spelling and hyphenation updates. Things like "develope -> develop" and "to-night -> tonight", that would not change the meaning of the text. Vernacular is not affected by these changes, nor would we want it to be. :)

Think of it more like modernizing spelling of Shakespeare, so that we can enjoy the text and not spend time parsing spelling like:

Had, having, and in quest, to have extreame,
A blisse in proofe and provd and very wo,
Before a joy proposd behind a dreame...

Some people might prefer that old-fashioned spelling, and it might be of some use to academics and historians, but I think the majority of casual modern readers would have an easier and more enjoyable time with light modernization.
> It'd be like replacing Google. You're basically talking market chaos and massive supply chain disruption, probably to the point of extensive loss of life

What? Granted an overnight transition could cause disruption, but in a few months, what couldn't be replaced?
Gmail? GMaps? Android? Youtube? Search+Adwords+GAnalytics? GCE? their CDN could be the worst, maybe? they all already have big competitors, and since Google's quality is minimal, it wouldn't be that hard to switch over. But you need a motivated company, i.e. just a little more effort than OpenStreetMaps or FastMail.
> Colonizing Mars is just the next step for our species.

Not quite. The next step is colonizing Earth. I agree we can do it if we really want to, and Dubai is a valid example. We may colonize mars in the future, but to me it doesn't make sense to try to do it now.
It seems like it requires a particularly narrow world view to equate censorship resistance with vice.

I've done a lot of work involving buying and selling virtual goods (not cryptocurrencies, think of currency in an online game as an example).

A lot of communities in these areas love bitcoin, not becuase they want to scam anyone, but precisely the opposite: becuase they are tired of being scammed.

Do you know what you have to do when you use Paypal to buy digital goods from many persons or companies? You have to send them your ID, a picture of you next to your ID, often confirm a phone call or email, and then pay an extra fee.

Because if they don't make customers do that, they will get scammed by chargebacks no matter what, and lose all of their money. People are tired of bullshit like Paypal, and that's why they prefer Bitcoin.

I agree with some points the author has, I don't think there's anyone that thinks the valuation of recent ICOs on the Ethereum network are anywhere near reasonable, but just because things are significantly overvalued doesn't mean the entire technology is for scamming.

Just like there's reasons to not exclusively use Amazon/Google, there's reasons to not exclusively use USD/Paypal/Banks/etc.
Fuck off; to the article.
At some point, you need to decide what you're going to ask something to build in an interview. It's probably been implemented before.

Yes, reversing an array is arguably lower level than an application engineer needs to go - but not by much (in some languages you will be doing this yourself). And if they can do that, they can do something comparably difficult.
What about the transaction cost to/from bitcoin? It seems like such a hassle compared to something like Transferwise which already gives decent transaction costs.
This is easily the most terrifying thread I've ever read on HN.
> My go to question is reverse an array (without using any library functions).

If you mean “functions provided by a library outside of the core” there are languages where this restriction doesn't prevent the kind of trivial solution you are trying to prevent.

If you mean “any predefined functions/methods” there are languages where this is impossible (e.g., since even literal array syntax is just syntactic sugar for the Array constructor method.)

Note that there are several languages that fall into both categories (e.g., Ruby.)

There are probably a very narrow slice of languages where this restriction, however you define it, really does what you intend.
I think the main issue that would have to be addressed is the "turn cash into bitcoin" step.

While I havent personally done an in person bitcoin exchange, I'd imagine that there aren't too many people doing it this way, and probably not in quantities of $1000+. I would love to hear about the experiences of people who have done this.

The other option would be to setup a bank account, which might be a bit of a challenge if the person is not a citizen, or perhaps not even in the country legally, and then there's the issue of the money now having a permanent digital paper trail (not bad per-se, but probably something your typical migrant worker sending money home might try to avoid (but seriously pay your taxes))

Lots of these comments ended up focusing on research, which applies heavily in litigation but hardly at all in transactional work. Justin confirmed in response to my other comment that their initial market is transactional, so perhaps what they have in mind is somewhat different (related to managing various transactional flows, like fundraising, M/A, etc.)
>But this nut is the Everest of retail. It will be a challenge to get it to fit into their model.

Looking at it the other way: Amazon knows it's bad at this, so it's acquiring the expertise.
What the hell is your point? That amazon treats unskilled labor in fulfillment centers less badly than KFC? Amazon has earned itself a reputation for being frugal/fostering a poor work life balance. You countered by saying that those stories only apply to seasonal "unskilled labor" in fulfillment centers. I am of the opinion that amazon should treat all of their employees well. OP is concerned about the impact amazon's culture will have on WF, which is apparently known for treating its employees really well (these employees would fall under the "seasonal unskilled labor" under your definition).
Agreed. I should have been more specific. It reduces the need to trust the person initiating the transaction. That person still needs to trust the entity that is supposed to provide value in exchange for that transaction.

Unless the blockchain supports contracts and you have a well coded contract.
I agree. How could a store that has a full range of products, with many organic options, at reasonable prices not succeed as well.

Whole Foods is too pricy for me for a full grocery shop but I can afford and like to eat better than discount stores.

> by this definition, lots of US soldiers are terrorists, they kill (sometimes intentionally, sometimes not, sometimes forcedly)

It's this kind of sloppy thinking that makes a rational discussion of this topic (and many other controversial topics) so hard. I wrote "intentionally target noncombatant civilians" and you essentially ignored this.

There is a huge difference whether you kill someone intentionally or non-intentionally as a side effect, or at least that's what the majority of people who seriously think about this topic agree upon. Intentional killings of noncombatant civilians by US army members are considered crimes or war crime, depending on the circumstances. They are often prosecuted. But I've already mentioned legal grey zones such as drone strikes in which the killing of innocent bystanders is not intended but taken into account.

> Of course, they [the Taleban] are defending their own place,

But they are often classified as terrorists, hence the example. Just to make this clear as well, the example is a bit ill-conceived in retrospective, since there is no doubt that Taleban as an organization are terrorists - they bomb cilivians in cities all the time. Of course, the definition of a terrorist organization is more complicated than just "they always intentionally kill civilians".
Ask HN: What video game elements do you wish you could use to motivate you IRL?
For example :

- earning rewards for doing actions
- earning bonus rewards for teaming up with others in groups or guilds
- getting 'gratz' from your friends when you reach a new level
- climbing a leaderboard
- customizing your character with look, outfit and gear
- bravely going into new territory with the risk of dying and losing time, gear and progress
- grouping up w/ other players to defeat a dungeon
- grouping up w/ your guild to defeat a raid
- dueling other players or groups for bit loot and glory

Any ideas on how you would like to see things like this brought to real life?

Say 'earning a reward for doing an action' could be using an app to record that action and the app rewarding you with a small amount of in-app currency that you can use for other things?
Amazon is simply too much - time for the monopoly-busters to break them apart.

What exactly does Amazon have a monopoly on?

Selling books? Nope, Barnes & Noble and Walmart and others compete there.

Cloud computing? Nope, check Google, Microsoft, IBM, Racksapce, Linode, etc.

Selling other random stuff on the net? No, Target, Walmart and a bazillion specialty sites also do that.

Groceries? Obviously not.

The idea behind anti-trust / monopoly law is generally to prevent a company from leveraging a monopoly in one area to gain excessive control in another area. I don't see how anyone can argue that Amazon are doing anything like that.

Being big and successful is not, in and of itself, wrong.
