And so insecure too, my fax machine's number used to be 1 digit off from a pharmacy's .... I used to get more faxes of other people's private prescriptions than genuine faxes intended for me
> Has anyone made any real progress in solving this problem?

The reason they haven't is that the law puts the burden of fraud on the payment processors. The dispute resolution overhead is the same for a $.10 transaction as a $100 transaction, but if that average cost is $.30 then you can't have $.10 transactions and the fee on $1 transactions is onerous.

Using some cheaper less effective dispute resolution for micro-transactions doesn't work because if it's possible to consistently scam it but only for a dime then people will just scam it for a dime in a for loop.

This is why the off-chain Bitcoin processors have lower transaction fees -- they don't have this problem. But then the problem is that the customer has to get some Bitcoin and if they have to buy it with a credit card we're back to square one.
It depends on how much reliable sun the location gets, and how much wind. Wind is often cheaper. Wind also keeps going at night.

Free speech vs. virtual ‘action’ on the early web (LambdaMOO)
"transaction-level" pooling might be a more apt description. Instead of assigning each incoming connection to a dedication upstream connection for the entire duration of the incoming connection, it assigns the upstream connections on a per-transaction basis. When each transaction ends, the upstream connection is returned to the pool. A better description is at https://wiki.postgresql.org/wiki/PgBouncer.
So before Netflix introduced a VPN ban, Netflix didn’t exist? Same for Amazon, Apple, etc. etc.?

No. Rights holders groups asked for it, and they said yes to increase their margins.
Moved to Show HN:
I opened sourced the platform that I made to serve my personal side projects. It's basically an open source version of Heroku. Similar to Dokku, except it comes with Free SSL certificate support, clusing support, web interface and etc. Let me know what you think :)
Interesting. Or put more tersely,

Let O be an open set in R^n. There exists a smooth function f: R^n -> R with support cl(O).

Off the cuff, I'd try proving this by covering O with bump functions and trying to glue those together. I'll try thinking about this more when I've got time. :)
> Typed Racket supports refinement types and dependent function types. Previously an experimental feature, refinement types allow types to describe more interesting properties of values, especially integers. For example, this type shows that the max function always produces a number at least as big as its inputs: (-> [x : Integer] [y : Integer] (Refine [z : Integer] (and (>= z x) (>= z y))))

Did Racket become a better Haskell while I wasn't looking? What's the catch? Those look like some powerful type system features.
The value lies in being able to create a permanent ledger that cannot be changed for your products that anyone can access. For example if this was around during the time of Da Vinci, he could have recorded his paintings onto the blockchain and attached a QR code to the back of them. Then today we would be able to scan that QR and trace the painting back to him. This is a huge deal as some art experts claim almost 50% of paintings in museums are fake.

Another use case would be for cars. Each car could have a QR code attached and every time a mechanic does a repair they could add that service record to the car's ledger, creating permanent service records (a big issue faced with buying used cars is a lack of service records).

The use cases are endless. And when we do take it off of the testnet and onto the actual blockchain we want to bring the cost of gas down significantly so that it will almost be like paying nothing. We are adding the explanation to our page very soon!
And thanks I just posted on your website!
Yes, completely agree that each dataset requires decisions to be made that can't be automated, but there are huge opportunities for tools to assist users in understanding what cleaning decisions they might want to make and how those decisions affect the data. Most data cleaning tools do a very poor job of helping the user visualize and understand the impact cleaning has on data - they're usually very low level (such as pandas).

As an example of a tool: Trifacta (disclaimer I work here) https://www.trifacta.com/products/wrangler/. We're trying to improve data cleaning with features such as suggesting transforms the user might want, integrating data profiling through all stages to discover and understand, and transform previews so the user can understand the impact.

I think there's a huge opportunity for better tools in the problem space.

>The clinic has digitized its own patient data. But its electronic system can’t connect with other clinics’ records. So when doctors want to retrieve records from another office — an ultrasound for a pregnant patient, for example — they have to turn to the fax

Haven't these people at least heard of email?
i also don't agree, they have found a group that likes to work together, likes to solve problems together. i think that's a primary motivator. sometimes i see my colleagues more than i see my family so it better be people that i enjoy working with.

Don't think of it as asking for 1 dollar. Think like this:

Say if you walk up to me irl and ask for a dollar, I'll be like, sure here's your change and open up my wallet.

Online, asking for one dollar is too much mental overhead. Its not like people don't want to pay, but you need to make it easy for them to pay you.

Personally, I would stick with ad revenue instead of 1 dollar payments.
Watch the video, this thing is mobile, but has the resolution of a full size device. But yes, thinking it will be an at home device is a bit of pipe dream.
I never spend more than $0.10 on transaction fees for bitcoin. I mean, you could give $5 if you wanted to, but why would you?
If I was sending a dollar I wouldn't pay more than $0.01 or less for the transaction fee. And for something so cheap the merchant shouldn't bother waiting on confirmations. Exploiting 0 confirmations isn't easy, and it's not worth the work to anyone for a dollar. Even with sub cent transaction fees they'll still settle faster than 3-5 business days.
Email is roughly as secure as you care to make it. Better than stupid phone lines at least.
It's always interesting seeing the conspiracy theorists emerge on Hackernews, of all places. Gavin himself stated he should have removed his own commit access due to inactivity. Of course, it was removed for him due to being social engineered by Craig Wright (the fake Satoshi guy evading taxes).

>Banned people created /r/btc and this sub is growing quite fast

No, Roger Ver uses that subreddit to advertise his commercial website - breaking reddit.com's terms of service.

Also, Ethereum is in a quagmire regarding scaling. In fact, I do believe it's cheaper to spend bitcoin now than it is ether ($0.25 in gas per transaction).
Don't bother, the HN crowd will downvote this hard, bitter truth. I had this conversation N times, my argument is roughly this: "There's no legit use of bitcoin. Main usages are a) pyramid-like hold-and-hype b) illegal money transfers out of China. No, ordinary people don't want to use it for international transfer because you need to go through hops to get Bitcoin on the sender end, even worse the receiver needs to do something to get money and at the end of the day you have no idea how much money the receiver actually gets. And let's not even discuss outsourcing the security from banks to customers."

France Is Running Out of Butter for Its Croissants
They've heard of it, but aren't going to use it. Email is generally not encrypted when stored at rest in many hops along the way, which should be considered insecure.

While fax is unencrypted, it's generally not stored in any intermediate systems and has established history of being considered HIPAA compliant.
Yeah these are the people I like to talk to. I've built some great apps based on things I've been told by these folks.
At least part of it is that no one has come up with a document format that suits everyone. Doctors want to scribble notes with a stylus but when you digitize that you don't really gain anything, other systems don't know how to interpret those scribbles. Suggesting doctors enter fields into a form instead of scribbling notes will get you no where, doctors are the stupidest and most stubborn smart people you will come across. Not that this is perfect anyway, sometimes you really do just need those random notes that don't really fit anywhere else. Some of the younger ones will type instead of scribble, but it's still mostly free form text and not data. The industry is still stuck on the idea that one doctor visit == one patient record as well, the thought that doctors could input blood pressure readings in their own section and have it display the history as a spreadsheet (or even a graph) has not gained any acceptance.

So it's not just about how we transfer information but how it's created as well, we haven't invented the right set of primitives to store it in the first place. I've spent a bit of time thinking about how I'd improve things and think things need to be more like emacs org mode or a jupyter notebook than any current EMRS, but even that might have to wait for a generation of scribblers to die.
That's a pretty rude comment. I'm sure cpncrunch understands that, literally, not everyone on the planet can afford to pay a dollar. Please adjust your tone.

Generally the Kelly Criterion is the optimal play strategy for the entire game if and only if your utility in final payouts is the log of the payout.

In the Haghani & Dewey 2016 experiment log utility is violated in two ways:

- A $250 cap on payouts.

- The fact that $250 payout to participants was on TOP of participant's current wealth, making utility approximately linear.

>to the detriment of high fees and a clogged network.

Sigh. It is astonishingly cheap to spend bitcoin right now. In fact, I paid the absolute minimum fee (1000 satoshis, or a handful of cents) the other day.
On what basis are you calling this assertion "clearly not true"?
Neither of those services blacklist based on bad netblock neighbors anymore. The only one I've seen to that in years is AT&T, and it has only been a problem with them sporadically.
Legally they're fine because the responses were anonymous and none of the users would reasonably believe that their responses would remain completly private.

Ethically (at least in my opinion) is the same, as long as they're kept anonymous and there's nothing personal or private in the responses they can use them for any reason. Especially because they were given in lieu of payment.

I have no experience with ExpressVPN, so I can't help you with that.

But in a vlog I've watched on Youtube, the host of that vlog said "Over the last coupe of days, ALL the VPN is been very difficult to use". So, I guess that includes ExpressVPN.

I wouldn't try to build A startup.

Instead I'd focus on being a 'special forces team' for people who have a good idea and some product &/or traction but need more people with your skill sets and access to capital.

You would then be essentially super hands-on investors, who could add significant value (although that really depends on you - you could also be super disruptive).

Over time you'd pick up a portfolio of companies that you've worked in and on, then exited and allow the initial team and new members you brought in to flourish.

While you rinse and repeat and slowly build network effects and improved learnings along the way.
Is this site a giant bubble? I spend a lot of time here and don't think of it that way.
> The existence or not of collusion is independent on whether said collusion was ineffective or unnecessary.

Am I misreading you or are you effectively saying that non-existent collusion can be as effective as existing collusion?

I've read it three times now.

(As usual I guess I should point out the sitting POTUS is and was not my preferred choice.)
Thanks! That paper is extremely helpful. Still, there is one thing missing to complete the picture for me right now. At the input, I have a list of words that I want to index or query. When indexing, they usually form a sentence, when querying, they might just be keywords. But in both cases the words will usually be selected by the user/author in such a way that a human that reads all the words from the input together is able to disambiguate the meaning of every word. This is precisely what I'm missing.

Let's say the user entered three words: A B C. You look up each of them among the vectors and discover that there are three matching vectors for A, four for B and five for C (and for the sake of generality let's assume that there are more words than just 3 in the input, so it's impractical to test every subset of these words for co-occurrence). How do you jointly select the correct vector for each of the words?
yeah, so when you pay with cryptocurrency there is no real information about you, now this is just the first part, and if we stopped there, you would be correct. But many sites use the address data necessary for credit card transactions and append that to your user profile, but sites that accept cryptocurrency do not because it is not necessary to complete payment or distinguish users.

so secondly the bitcoin transaction would have been executed by someone else, from a mixer. The mixer was instructed by my transaction to it from an opaque blockchain, as explained earlier. Your rebuttal implies you have never seen the differentiating features of Monero. It is a public blockchain, but transactions are not linked.
There are several reasonably well-known languages that bridge the functional and imperative worlds in one way or another. However, I’m looking for more than just that. In particular, I’d like to have good tools for both imperative/stateful and functional/data-transforming coding, but all within a safe, structured environment in terms of effects/external interactions/observable behaviour.

Now, I am by no means a Lisp expert, so it’s entirely possible that I’m completely unaware of something here. However, I’ve yet to encounter much of an effect system in any flavour of Lisp. Indeed, it’s hard to see how the sort of explicit visibility and control of effects that I’d find useful could be achieved in a language with primarily dynamic typing using any of the approaches I’ve encountered so far.
No, Parsons is at least a 2-trick pony; from Wikipedia:

"In 1984, he founded Parsons Technology in Cedar Rapids, Iowa, and began selling MoneyCounts, a home accounting program. In late 1987, Parsons was able to quit his job and focus completely on selling and overseeing growth of MoneyCounts. Eventually, Parsons Technology grew to be a 1,000-employee, privately held company. On September 27, 1994, Parsons completed the sale of Parsons Technology to Intuit, Inc. for $64 million."
Create a protocol or API spec on top of HTTPS or something else and use it. I don't know where you ar at but surely the government can just say "hey guys support this secure protocol before 2022 or you're out".

I can log on and read any of my medical records at any time and the information is aggregated from multiple sources. What's the issue?

If you use fax you won't even be able to see some kind of central audit log for your data. That's pretty crazy.
This might get downvoted, but let me play devils advocate... the $1 is too cheap. You don’t value my time if you’re making me whip out my credit card and go through the painful process of checking out for transacting only a dollar from me. You’re also extremely downplaying the value of your product. if it was only worth a dollar, you would likely not be building a startup around it :)

Most people don’t know how much something is worth. Try not to lower price, rather, increase value.

Under the sad faces, I’d change the messaging. Its generally understood (even by the layperson) that the true cost of technology is very low. What this really costs, and this is true, is the time-value of your development team (and associated market salary). “It takes real people to build and maintain this” might be more effective messaging.

All that said, this does seem like an interesting way to gather user feedback. Good luck!
Just purchased, thanks for the heads up everyone, I'm looking forward to this.
If email is encrypted, why does it matter that it is stored in any intermediary place along the way?
Edit: turns out it's just a little harder to find.

That's regression. Despite having vastly more memory than 20 years ago I'm not getting anything more done with it.
Online micropayments is still a woefully untouched market, it was supposed to be the wave of the future some years ago, but never went anywhere.

I won't pay 10 dollars a month (each) to the NYT (LAT, WaPo, et al) for a subscription I might quite happily pay 5 to 20 cents for an article though. I can see a service that functions a lot like EZPass, you load your account with 5-10 bucks, you agree to pay by clicking a payment button on a landing page on a website, the rest is mostly automatic, require more than just a click thru for anything larger than say, 25 cents. You could even set it up so it doesn't prompt you to pay until you're more than half way thru too.

Yes, It'd take some doing to build infrastructure and get content providers online, but it would eliminate a lot of the mechanics of paying for news, information, online media and other like content (as well as many of the privacy and practical concerns of ad based content payment).

The big thing is to make it content agnostic, it can't be part of apple, google, facebook, whatever, it needs to be something that functions just as a payment/escrow service, not part of some other media empire - part of the utility of such a service is universality. I'd also steer clear of person to person payments, large transactions, pretty much just be a one-trick-pony (at least until you have wide penetration), and only go after small payments - all of those other markets are well served by a multitude of providers, and would serve as a distraction from the primary product.
Depends on your supermaket POS vendor. NCR has by far the most expensive offerings, but there are a few dozen smaller vendors, some of which have reimplemented a few of the core concepts of ACS, BR Data and other components, thrown them all in one package, and offered it at a much more reasonable price.
Given the regulatory process, I would envision AI along the lines of "region proposal". That is software to highlight or draw one's attention to a certain portion of the image that "may" have X or something interesting. That's in contrast to diagnosis software where it'd say this portion "is" X.

I should add there are several hand-held portable ultrasound machines, like from SonoSite and Clarius, and would agree that the selling point here is the price point. To the best of my knowledge, the cost of ultrasound machines has gone down by two orders of magnitude with somewhat comparable resolutions. I believe the top-tier machines with the best image quality or resolution are still on the order of >$100k (Philips Epiq for example).

The cloud software offered by Butterfly should also be interesting if done well.
I was thinking the same thing, that's a really cool feature.

I like this idea of avoiding a paywall with a reason.

I read many articles from The Guardian, who use a banner ad to promote their premium subscriptions. Due to my unstable life, I can't commit to regular payments from one bank account in one country for more than a couple of months at the longest.

The Guardian and many other news sites have entire sections dedicated to Bitcoin. But they don't accept it as a payment method.

I emailed their customer feedback, and was pleasantly surprised at the encouraging reply. Their management will be discussing whether to accept Bitcoin as a payment method.

If the news websites start accepting Bitcoin, they'll be more likely to post less sensational articles about it, and the value proposition to the end user becomes more clear (remove ads). The fact that Bitcoin payments aren't traceable encourages factual articles instead of promoting articles that indulge the political opinions of the people funding the news agency.

I'd be curious as to what the payment model for a GP to own a conventional ultrasound machine would look like in Canada, the US, and the UK. It's my understanding that the pocket ultrasound at it's price point would essentially pay itself earlier on while serving a purpose of being a triage tool.

Given the size and cost of a conventional cart-based machine, I think the pocket one is more well suited.
