Proposal: AWSCoin, GCECoin, AzureCoin
There are uses for decentralized, proof-of-work crypto-currencies...

But I wish that Amazon, Google, Azure, and other cloud computing companies would introduce Coins that you could use to pay for their services. I admit that they would have to develop these coins, and that it would not be trivial, but I think the value would be immense.

I know you can already buy Amazon credit, etc. But they don't work at all like the crypto-coins do. If the Cloud-Coins had a public address that anyone could generate, and a private key you had to use to access your own account, and you could call web APIs to transfer from your account to someone else's... And if you could do it in units smaller than a United States Cent?

Even better, if I could issue a temporary key to give to some service, allowing it to charge me at a specified subscription rate (for instance, "Up to $3 US in AwsCoins, per month"), that I could later revoke when I felt like it...

I just feel there's room for a ton of innovation, here. And the coins would be backed by something real. There'd be no investment phase of the currency. It wouldn't be a Ponzi scheme. The original creator wouldn't have 1/20th of the entire market. We wouldn't be wasting compute power and electricity proving to other computers that we were doing work.
We had the same complaints about cell phones, especially with handsfree headsets. It was simply too creepy to have people walking around with a small box mushed against their ear ... or worse, just walking along chattering into the air with nobody around.

Well, we still have the same complaints, we just find it so useful we've accepted the "cell phone zombification" of society.

HUDs will be the same, and like Bluetooth-enabled earpieces will gradually disappear into barely-visible devices.

Yes - this is the problem that most feedback sites have. I believe that Glassdoor uses Facebook as the verification. That way they at least know you are a real person, even if they can't explicitly verify that you actually worked there.
The scan of the license plan is not really the issue, it's the collecting of the scan, tagging it with GPS, and aggregating the scan into large, permanent databases that can be accessed by both government and private corporations.

If all you do is scan a plate and display "car payments past due", or discard the scan if the car is not wanted, it's not all that different from a human looking for a car.

But these folks are creating historical databases that capture everywhere you have ever been. These sorts of databases can be mined retroactively to discover all sorts of sensitive information, similar to what was pointed out by Justice Sotomayor in the recent GPS tracking case, U.S. v. Jones:

"GPS monitoring generates a precise, comprehensive record of a person's public movements that reflects a wealth of detail about her familial, political, professional, religious, and sexual associations. See, e.g., People v. Weaver, 12 N. Y. 3d 433, 441-442, 909 N. E. 2d 1195, 1199 (2009) ("Disclosed in [GPS] data . . . will be trips the indisputably private nature of which takes little imagination to conjure: trips to the psychiatrist, the plastic surgeon, the abortion clinic, the AIDS treatment center, the strip club, the criminal defense attorney, the by-the-hour motel, the union meeting, the mosque, synagogue or church, the gay bar and on and on"). The Government can store such records and efficiently mine them for information years into the future."

While the government can currently look up your license plate information, or track you manually, they are limited by their resources. (From Alito's opinion in U.S. v. Jones: "But it is almost impossible to think of late- 18th-century situations that are analogous to what took place in this case. Is it possible to imagine a case in which a constable secreted himself somewhere in a coach and remained there for a period of time in order to monitor the movements of the coach's owner?") A nationwide database of historical location information -- that may not currently require a warrant under the 4th amendment to access -- is ripe for abuse. Letting private companies access the data is also scary.

These data brokers are probably right that they don't currently violate any privacy laws, however. But that just means we need to change the laws, as I think this most definitely needs to be a violation of privacy.
This has been predicted by Ethereum's founder (and others, I'm sure). There will be millions of crypto-coins in the future. Any company could launch its own crypto-coin, as some sort of "shares" from the company, and a way to fund the company as some sort of mini-IPO. Think of it like Kickstarter for crowdfunding, but you'd actually own part of the company by buying their coins, and your coins will grow in value as the company's value grows. You could also easily sell those coins back into other currencies whenever you want.

Of course, this would be much easier if all of these millions of coins would be built on top of a crypto-coin platform, where you could also have P2P exchanges that can exchange these currencies much more easily and securely than a centralized exchange can. Things could get easier still for doing this, if companies just become Decentralized Autonomous Organizations. That's basically what Ethereum is trying to achieve, among other things.

This is both fascinating and disturbing at the same time. I think many game developers (myself included) struggle with monetization in a market that largely demands F2P games. Using tricks like these is a constant temptation and it's important to see how devious these methods are in their manipulation of gamers. Kudos to Ramin for writing such an informative summary.

I currently teach math to at-risk students. I don't read all of these submissions about math education, but I skim the comments on most of them. The comments people make change the way I teach math.

I have always done a decent job of teaching math. I focus on helping students understand concepts, even when they are focusing on mechanics. I use words like "shortcut" and "more efficient method" rather than "trick" when showing students more efficient ways to solve problems. I have students do problems and projects that relate to their post-high-school goals.

But with the routines of school life, I get away from the fun of math from time to time. The comments on these submissions often remind me to go in and just tell stories about math:

- "Hey everyone, did you know that some infinities are bigger than other infinities?"

- "Hey everyone, do you have any idea how your passwords are actually stored on facebook/ twitter/ etc.?"

- "Have any of you heard the story about the elementary teacher who got mad at their class, and told everyone to add up all the numbers from 1 to 100? One kid did it in less than a minute, do you want to see how he did it?"

Thanks everyone, for sharing your perspective on your own math education, and about how you use math in your professional lives as well. Your stories help.
But here's where I disagree with you: it costs literally millions of dollars to get the needed state money licenses to legally operate a Bitcoin exchange[1]. FinCEN has been very explicit that they consider Bitcoin exchanges to be money transmitters.

So those millions are money that could go toward building the infrastructure you describe. Bitcoin companies like Coinbase who have finished their Series A have to spend their runway on licenses instead of developers or infrastructure.

It's a huge problem, whether or not people are willing to admit it.

But thank you for arguing in a rational and non-bullying/non-contemptuous manner.

I was reading a review of a game. The game was a clearly labelled demo, and had a single IAP to unlock the full game. The reviewer called this unsavoury.

That's a great shame because it means people offering demos with honestly priced games are called unsavoury and people offering these scummy monetization tricks get more money and cash.

"whimsical Scandinavian clutches" does not sound very evil to me. It would have sounded more evil if she'd just said "clutches". A lot of the wording to me makes it sound light-hearted, rather than as any real criticism of LEGO. The kind of complaint lots of parents will make of them while still going to the LEGO store and getting just as excited as their kids about some new set or finding just the right bricks for some project.

Since fidotron has been piled on, let me defend the point in his/her post. Good mathematics has come out of being worried that what other mathematicians have done isn't quite right, and I think the perspective of the article doesn't acknowledge that.

For example: Cantor's theorem is quite true, only cranks doubt it [1]. But many mathematicians take it to have the corollary that cardinalities greater than that of the natural numbers exist, which does not follow: it is perfectly coherent to say that constructions such as the power set of natural numbers do not exist as a definite whole, and so do not have a cardinality. These kinds of doubt have driven constructivism which has led to interesting work in topology, measure theory, and type theory, and led to such useful applications as calculators for exact real arithmetic.

Cantor's paradise seems to be coherent (likewise I would be deeply surprised if large parts of mathematics turned out to be misconstrued) but the assumptions of large cardinal set theory are grandiose and poorly justified, and yet for a long time those people who wondered if it was wise to embrace the whole edifice were marginalised. It seems that now there are many more mathematicians who are interested in revisiting this perspective [2].

To put Wiles' metaphor in perspective, it is good if some mathematicians step outside the mansion from time to time, to see if the superstructure is up to all the crashing about that happens in the dark rooms.

Ask HN: I've bought a domain for my city, any ideas on how to use it? 
Hello,

I've bought a domain similar to my city name in Italy

Vicenza -> veecenza.com

I'm looking for ideas on how to use it and get some little money to fund my other real project.

I was thinking of using it for foreign users, maybe events but there's already a tons of website.

What might be interesting for a tourist to find in such a website?

If you visit the website now you'll find a couple of images and three links, just testing some themes, nothing serious.

Best!

While I agree that Grunt isn't rocket science, for purely front-end developers who aren't familiar with build tools, it can be quite challenging to get started initially. In order to start using Grunt you'd have to...

1. Install Node

2. Figure out how to use npm and package.json

3. Install the Grunt cli.

4. Install local Grunt.

5. Figure out exactly which Grunt plugins you need and install those.

6. Create the basic scaffolding of your Gruntfile, hoping that the references you use aren't outdated.

7. Figure out exactly which options each of your Grunt plugins need.

8. Do some debugging when you got something wrong in one (or more) of the steps above. Problem is, since this is your first time setting it up, you don't know which step you got wrong.

For someone unfamiliar with the Node & Grunt ecosystems, this could easily be a multi-day project. If you're simply putting out some static brochureware sites, then it might make a lot more sense to just pay for a GUI tool to handle a lot of this stuff for you.

"Branding agencies use proprietary type families when they're the most appropriate for the job"

Except... they sometimes don't appreciate the breadth of the 'job'. For agency A to get their 'job' done, using fonts ABC works just fine. But now when that same font needs to be use in other areas they're not licensed for, their client either can't have the same brand experience in other media, or has to pay a heftier price to do so, or is running afoul of the licensing terms.

This is a couple steps above people just going to google images and grabbing whatever images come up for their own websites. Still same licensing/terms-of-use problems, just with a higher price tag attached. And somehow, when people are using big fancy agency XYZ, they think (rightly?) that the agency always knows what they're doing (often they do, but sometimes they don't).

The entire post was enjoyable but I found the last paragraph to have the most actionable advice:

What’s much more useful is recording what the deep insights are, and storing them for recollection later. Because every important mathematical idea has a deep insight, and these insights are your best friends. They’re your mathematical “nose,” and they’ll help guide you through the mansion.
Very good advice. For an excellent primer, I recommend Mindfulness in Plain English[1], which has been around for 20+ years and remains one the best and most recommended books. There is a little mystic stuff! but it's easily ignored.

iamsalman offers a great response. Legally (and conceptually) there is the idea of a collection, a compilation being valuable in and on itself: this has been enforced to prevent people from selling phone books and TV programs without paying the original ‘compilers’, phone companies and TV stations, not as operators but original authors of an exhaustive description. Collecting changes useless information into, anecdotes, into a usable product: that’s the whole point of those companies, they (presumably by contract) guarantee a return rate that makes them economically sound; that changes the nature of ‘looking around’.

This idea is essential to all the creep factor around Google’s recurrent controversy: the problem is not taking street pictures, but guaranteeing that any house can be seen by anyone; it's not to murmur in your boss's ear ‘that’s the sub-commissioner in grey’ but potentially matching anyone’s face to their full public history. This is what made every page of a phone book precious, and every post-it with a phone number on it worthless.
>we have a system of mathematics built on a few basic principles (that you would not disagree with) and deductive reasoning

I think it's even better than that; mathematicians don't necessarily care whether the reader 'agrees' with the axioms, or whether they're in any sense 'true' or 'false'. Mathematics is always of the form 'if these axioms are true, this theorem follows from it'.

The real world and the notions which people consider to be self-evidently true is just some messy slimy gooey gunk best left to psychoanalysts and theoretical physicists and sewer workers and the like.

It is worth pointing out that the majority of these sites do not store patient data or any privileged information, they are informational brochure type sites for surgeries to show their operning hours or specific health awareness campaigns, hence the lack of interest in centralising or updating them. They could be hacked and defaced I suppose, which wouldn't look so great for the NHS, but they won't be running on NHS servers or controlled by NHS IT. The XSS issue is a real one, and they should probably not allow subdomains of nhs.uk to be used for gp surgeries (the most likely to have terrible websites as they buy them in themselves).

Patient data is typically held in secure systems like emis etc. run by one of a few large firms which have contracts with the NHS, so not on this sort of informational website.

I was expecting a more critical piece as well, but I'm not sure the words "speak out" gave me that impression as much as the fact that it was (a) a survey about Java and (b) HN front page news. Java is not always a popular topic here.

One could interpret some of the answers as a bit critical of Java (or the community), but not Java 8 specifically. The fact that 22% of Java devs are using a release that is 7 years old and hasn't been updated in a year isn't something the Java community is likely bragging about.

I mentioned elsewhere in the thread that the takeaway for me was that 83% were excited about lambdas, which Scala already offers, and the notion that Java's future updates might start looking more like Scala. So the survey may suggest "why not just use Scala?"

I'm actually hoping for a transition to a situation where your favorite web framework, will come with its own web-based IDE.

Esspecially at the web-development side of things, IDE integration isn't optimal. It's not so much that the languages themselves need better integration; it's the frameworks, and the abstractions and tooling they bring.

When it gets this easy to create a web-based IDE, why even bother trying to develop a one-size-fits-all super IDE? Why not just have a simple IDE that targets one particular framework and its (likely opiniated) workflow? I mean, right now, most of that stuff, targets the command line as their primary UI.
