Im all for it. I moved back to Norway for a few years (2006) and most of the time there I only carried my debit card and no cash. I sometimes had a 200kr note in the same card sleeve for emergencies, but think I only used it once or twice in the 5-6 years I was there. Even remote pop up cafes/hot dog stands in the middle of nowhere took chip and pin cards.

It annoyed when I moved back to the UK that I had to start carry cash again as most corner shops in the UK have a minimum spend of £5 for cards. For valid reasons as in the UK the card providers charge a much higher fee than in Norway but it generally makes me avoid those shops.

The spread of contactless cards are also a blessing (in the UK and Norway). Paying for kids ride on stationary cars in shopping centres, even quick charity donations, etc are all great friction removing innovations.

Bad idea. Cash is the ultimate failure mode for on-site payment systems. What if the internet/phones went out? What if I'm visiting from abroad and my card is declined for potential fraud?
Dane here: only persons in trusted jobs (police, hospitals, etc) can look up a persons address. The avarage citizen cannot!

Denmark has much stricter laws for privacy than USA: Companies are not allowed to sell your address or phone number to other companies. So Danes don't mind giving Blockbuster their address because they know it won't be sold to 3rd party.

I think this differs widely from country to country. Here in Sweden our SSN equivalent (personnummer) is public information accessible to anyone by calling calling the register office and today even via various third party online services.
I still carry a single note around with me here as a backup, but I rarely have to use it. What has really advanced the process in recent years is MobilePay, a mobile app that let's anyone send money to anyone else with a phone number, provided they also have the app.

As for privacy concerns - my guess is criminals and those with privacy concerns will resort to pooling payments in some way - e.g. by converting it to some virtual currency and then back again. The tracking of regular people's transactions is of course getting much much easier.
Great project! I should do something like this too.

It would be nice if you place link to day 1 on each post, so that newcomers will have a bit more context when they get a link through twitter/HN/reddit
I'm Danish and I find this thoroughly distressing.

The payment processor, Nets, is a monopoly, owned by US investment firms. They have frequent outages and are unapologetic when they do. There is no transparency. They have a terrible privacy record (see https://en.wikipedia.org/wiki/2014_Se_og_H%C3%B8r_media_scan...). Until last year everyone down to their phone support staff had open access to everyone's payment records (see http://www.computerworld.dk/art/230818/alle-kundeservice-fol... -- in Danish). Despite all these issues they just laid off a bunch of people. Their only priority, it appears, it making money for the owners.

Money is a critical piece of infrastructure and these guys absolutely cannot be trusted to implement it. With more payment processors and a regulatory framework that forced them to provide decent service maybe cashless is not a bad idea. With the current implementation though there's a good chance it will be a disaster. It will certainly be a gaping vulnerability for anyone who should feel like targeting us; I wouldn't be surprised if all it would take to bring the whole thing down is one lone hacker.

Honestly, do you think you could get around having your accounts frozen in most any developed country currently?

And if your assets are frozen, chances are there's an arrest warrant for you and you have big issues.

There's a pretty hard limit to what you can do with briefcases of $100 bills.
If it's not too complex I would recommend an AWS,EC2 model - let customers pay as you go or opt in to pre buy for predictable and possiblely reduced pricing.

Brainteasers tend to follow a particular pattern. The amount of information the various Alices and Bobs and Charlies have seems at first glance to obviously be inadequate to the task they're given. Then a closer examination reveals that there's some sublte extra scrap of information, and you can generally assume than that the answer is to use that to trace out the possibilities to find the actual answer.

So knowing that, I just looked for what extra, non-obvious piece of information A and B had. It seems impossible to guess what the results of a coin-flip are in another room. But the players also know the result of their own flip, and so basing a strategy on that extra info is certainly going to be the answer. From there, since there are so few combinations of such a strategy, getting the right answer is pretty trivial.

I like this brain teaser (and I suspect the reason that Felton likes it as well) because it shows this general pattern for brain teasers very clearly. The "extra" piece of information is pretty obvious with a moments thought. And once you have it, the number of possible strategies using it is small enough that you can see the correct one quickly.

A lot of other brain teasers require a lot of pen and paper work even after you've guessed the "trick" in order to work through all the possiblities. So this is sort of a nice, boiled down "essence du brainteaser".
An actual fun problem:

100 prisoners are each assigned a black or white hat, at random. As always, they cannot communicate after the hats are assigned. Then they are shown each other. None sees own hat, everyone sees everyone elses hat. Then they are led into separate rooms and each guesses their own hat color.

They win only if everybody guesses correctly. What strategy maximizes the probability of that event?

I suggest that card providers would charge an even higher fee if nobody was using cash.
It seems HN is being trolled by posts from the past.
Interesting. I live in BC and Kijiji definitely isn't as dominant as Craigslist here. It's common to find jobs, second hand goods, and cars on Craigslist. I haven't heard anyone refer to Kijiji for anything here. Quite different from ON where Kijiji does seem to have the dominance that the article referred to.

Spotify already did that early on - the client was also a P2P node that would transfer music files from and to other clients. They shut that part down last year.
Just moved a bunch of our company's large downloads over to S3 recently (mostly BSP releases and drivers), and this would be awesome for that 100MB - 4GB package size range that they have!

Tried it with a few clients: Transmission does not seem to work, though (both web client, and GTK): "Tracker gave HTTP response code 404..."; rtorrent seems to be able to download (but looks like no upload?); deluge downloads well and also kickstarts the transmission clients.

I wonder what's unacceptable in the Amazon infrastructure for transmission... And the 80kb/s max seed rate mentioned in the comments might be a showstopper already.
1. The speed of electrons in wires is quite slow. Electrical signals travel much faster than electrons.

2. Light travels ~30 cm per 1 GHz clock cycle. That's approaching the point where we have to worry about it, but...

3. The speed of light constrains latency, not bandwidth. GPUs care much more about bandwidth. The advantage of using shorter wires is it allows increasing bandwidth more easily.

Ask HN: A startup runs at a loss for 6+ years, gets acquired. Was it a success?
I've mulled over this question for some time now. I've kept watching startups (both funded, and bootstrapped) that never generate a profit (not even close), don't get much traction, and then get acquired by some bigger name company. The founders celebrate the success of their venture and add it to their successful entrepreneurial resume.

But does it really count as a success? Is there something about economics that I'm missing? Is it only about how much money you get back into your (or your investors) pockets? Does the term acquisition actually mean more than "rescued from drowning"?

I don't want this to come off sounding negative. I just want to understand what I'm not getting. Thanks in advance.

The things that cause real problems aren't local (like long functions, big classes, etc).

They are global, like hidden assumptions about the stuff you interface with. Requirements regarding order of invocations of some methods of seemingly unrelated classes. Code that shouldn't really be needed, but stuff breaks when you remove it. Esoteric automaticaly generated code driven by xmls or .xlsx, that nobody really understand, but copy-paste when you need another special-case.

Is this really easier to manage for building things than other techniques? It seems pretty labor intensive.

Though I guess everything is labor intensive. And the end result looks solid for what it is.

I want to add to it as a former pentester: it's absolutely painful to read about these nitpicky "the world is going to burn if you don't modify trivial security setting X that will destroy user experience". Not because these shouldn't be included in the report, but because the focus is wrong.

As strayptr, I would also include the trivial issues as "informationals" in the report as you do want your clients to know about these for a number of reasons. However, most of my time would go to hunting for severe issues, where I defined severe on some mental ranking based on "difficulty to exploit", potential impact,... In addition, these issues were also where most of my attention went to afterwards, because you need to explain and educate development, testing and business on the issues, why you think they are important and how to best/quickest fix them.

In my opinion, building up relationships and having empathy for your client is very important. I would always try to have a chat with development/test/business to get a feel of where their heads were at. That would help me both while testing (what is important to them? how did they develop it? what is their maturity?) and while reporting issues (they would actually believe me, I could help them rank the issues and they would allow me to brainstorm how to best mitigate the issues for their environment).
Checks are not electronic. If you shop at a store, the transaction record says what items you've bought.

Nobody can stop the tax authorities demanding you to attach an invoice to every transaction a business makes. It would be trivially easy for businesses to implement it nowadays with the software they have. Many businesses do it this way already, if they use their invoicing vendor (xero,quickbooks) to accept the payment as well.

I've always preferred compressed earth blocks to superadobe (http://opensourceecology.org/wiki/CEB_Press). I think CEB has more potential to replace western buildings at a lower cost and low carbon footprint.
This is the same here in Iceland. We have a very high adoption rates for internet banking and through each bank you have access to the national registry and can find the SSN for everyone (even the prime minister) by searching by name or address.

Companies publish their SSN on their websites.

The key for recipient in intra-country payments is account number plus SSN.

Identity theft is rare. I've always found strange reading about credit card scams in USA where people go through your garbage and get a credit card in your name. Here you'll have to show up in person and identify yourself.

When I get my money out of the account because of deflation, why would I choose cash over, for example, gold? In financial unrest, holding cash gives zero return at best, and more likely a large negative return due to inflation.
I think it's more interesting to build temporary dams using this. It could be more robust than using ordinary sand bags. Their licencing could be interesting in this regard too:

"Superadobe is a patented system (U.S. patent #5,934,027) freely put at the service of humanity and the environment. Licensing is required for commercial use."
Going to the store and having a problem with one of the products, we looked at the registry of all my last purchases(that got recorded for using a discount card) so they could see I was right.

Just looking at the list it felt so wrong. Everything I bought, with the day on it, the person that attended me FOR YEARS.

I mean, they had all this information about me that even I do not have about myself so they could study me like a Guinea Pig.

Governments are collecting more information about us that the Stasi or KGB. Transcribing our phone conversations, our GPS position, and now everything we buy, where we buy it, when we buy it and soon with whom we do it.

This is a serious problem. We are predators by nature, the first thing hunters do is study the habits of their victims so they can find vulnerabilities.

Too much power in a few hands. This people also have the power to make money, and want to ban cash so they can force you interest in your own savings(negative interest or tax your money).
> I think there is a stigma attached going out alone though - I have random people ask me if I am alone and seem surprised by the answer.

I've been doing things alone a lot since I moved to another city. And it really seems weird to the people I talk to.

"Are you waiting for someone?"

"No."

"Are you alone?"

"No. Look around. There are so many people here."

I think the article is quite correct with the spot light theory. People are way too concerned about what others might think. So it actually seems to be a good thing that I mostly don't care about that.

One downside for me is that – I asked a random stranger about that – it seems I don't look approachable. She said, it seemed to her that she needed to say something smart to me rather than just asking me if I want to have a drink with her. I haven't figured out what the reason is but I would really like to change that.
> the "getting cash is free" myth

Can you explain what you mean by this?
The solution is for the lines to be operated prioritizing the community before profit, yes. We've agreed on the fundamentals but now differ in imagination of the size of the community.

Why not extend such egality to all citizens? And why do people have to get "screwed by telcos" first before it can happen?
> Private ownership of land in and around the cities is not common in the Netherlands.

This is only partially correct. Private land ownership exists (and is the dominant form) in many cities in NL, but there are a few prominent ones where 'erfpacht' (still) exists. In quite a few cases the annual fee can be bought out for a lump sum for a couple of decades or even for ever.
Really? I'm Dutch but lived in Denmark for a while. I gave CBB (a telco) my CPR number on the signup form and poof they had all my data. Impressive UX, but it scared the hell out of me.

Also a Danish social security card (the kind you show to doctors or hospitals, so you take it everywhere) contains your full address and the CPR number. Handy if someone finds your wallet, so they can bring it back. Unless of course they want to screw you over, because all relevant personal info is on that single card.

If you find a Dane's wallet, you can basically do any kind of business on their behalf that doesn't require showing a picture ID.

The other comments in this thread make an excellent point on how this doesn't make sense (extremely long investment period, unusually high interest, no inflation...).

However, my $0.02 is time. If you can afford a daily $5 coffee, the time it takes to make yourself a cup of coffee every day will cost you a lot more than $5.

Not to mention the fact that if you can afford $5 a day, you 're probably stable enough financially to save up for retirement anyway.
I've found companies typically use monolithic development because they don't get all of the benefits of modular development. e.g. they don't re-use code cause they only have 1 website (and don't care about open sourcing). I'll stick with modular all the way. :)
> Not such a good feeling. Stuff like this happens sometimes when people go to restaurants alone, I guess.

I go alone at restaurants pretty often, and what you described (more or less) only happened to me once: after I had finished my meal I went to the restroom. When I returned I found out that the book I had left on the table was no longer there. I asked the waiter about it (this was a fancy restaurant, where I go once in a blue moon), and he told me that the Italian tourists from the table next to me (some self-important shmucks) had told him that I had gone away for good, without paying.

Anyway, other than that eating out alone is pretty nice. I generally have issues with eating food in front of other people while talking and socializing (apart from very close people, like family or SO), so in this way I can eat whatever I like at whatever pace I want. Plus, I have like 4-5 or restaurants to which I go pretty often and is always nice to see that the people from there know you pretty well. May be because of the larger than average tips I leave at the end, or because they feel that I look strange eating out alone :), I wouldn't know, is nice all the same.

And about your relatives' piece of advice: In general is true, but is way, way harder when you find out that you are (and have been, for some time) alone by yourself even though you had been surrounded by all sorts of nice people who supposedly should have cared for you (family, close friends, SO etc).

Our lessons learned regarding the Producthunt algorithm
Hi there,

On May 6, our platform StartupCVs was surprisingly featured on Product. At the end of the day, we had roughly ~380 upvotes and were ranked 2nd that day by number of upvotes. However, we obviously made many mistakes - and I want to share our learnings. The day started off very well - we were at the top of the list and gathered great traction - but during the day, our ranking (not by number of upvotes, but placing in the list) slipped and we could not regain the first place. Obviously, being listed at the top during (PST) daytime would have had a positive impact.

Our main takeaways:

1) No direct-links! Do not post direct-links - ideally refrain from sharing
We shared the link with our family and friends/networks (as probably all do) - and we and supposedly some of our friends shared the direct-link.
Apparently, when you do that, the ranking algorithm "punishes" you and your ranking slips (while you may still gather many upvotes). Now we know that Producthunt prefers and incentivizes "organic traffic and decision-making". Fair enough! Also fyi: please do not overestimate your own impact. Producthunt reaches an incredible audience. In our case, we used Productfriends.com to engage with our upvoters - we quickly realized that we barely knew any of our upvoters. Regarding Productfriends: this webapp helps you understand who and how influential your upvoters are.
