Well if the coin can be deactivated when it's out of range, that would mean the coin has to be "smart" because it wouldn't be the phone app doing the deactivation but the coin itself. In that case, why couldn't the coin take extreme measures and just wipe its memory? Inconvenient for legitimate situations where the card is out of range and not accidental ones, but I imagine it's quick process to reload the coin with your card(s) data.
that kiva system is very cool, here is a tedx video about it, and some words about the theoretical min-max parameters mentioned.

Perceived low risk :)

BTC is a nice hedge against that. I think people are beginning to realize that.
I think "standing on the shoulders of giants" is the cliche you're looking for.

- Looking over the examples from the blog post, those aren't really from 'first principles'. They are assuming cars and an internet and other huge innovations. I think the real message should be 'double check your assumptions'.
"Anyone operating in a template-driven manner is not reasoning by first principles."

I'm saying that when you want to solve a problem, you don't use a checklist of which "reasoning from first principles" is an item. "reasoning from first principles" would be the template. It's an approach that someone spoonfed you. There is no contradiction here because we're speaking about the type of approach, not the particular sequence of steps you use to arrive at the solution. Of course you can be creative with these steps once you know the type of approach you're taking.

"I'm not sure what legs your argument has, we might as well say that speaking an existing language like English, French, or German makes us robots by forcing us to communicate within a well-defined and rigorous communication structure."

Natural language is well-defined and rigorous? That's not true.

"The fallacy of an individual with regards to reasoning is not a function of the fact that methods of reasoning are identified"

I don't care that it's labeled, per se, as long as people are discouraged to act like I mentioned. If the act of identifying and labeling thought patterns promotes laziness, then I am justified in being against it. But anyway, that's an empirical claim and you haven't provided any real reason for why you think it's false.
The answer to this is complicated and I'm not going to try to cover all the angles of it, so I'll simplify the answer with this: it depends on what you value and what you're willing to pay a premium for; if you care deeply about the optimal ratio of commodity functionality versus price, then the iPhone 5s (or most any Apple product) is probably not for you. That is NOT meant to be a snobbish, classist, elitist jab and I mean that respectfully.

In a similar vein, yes you could do similar things on a $500 Lenovo laptop compared to a $3000 Retina Macbook Pro; driving a Tata Nano or Honda Civic will get you to your destination just as fast (within reason) as a nicer car. Buying the cheapest food possible will get you calories just like more expensive food... the list goes on and on with other things (clothes, coffee/tea/wine, jewelry, etc).

So ask yourself: what did Apple value when they designed and manufactured the iPhone 5s, which are different than the values used to produce competing products? If those values are similar to your values, then it's worth every penny.
How to make a bad title worse.
I want chip and pin cards SO BADLY here.

Mainly because it would make my trips to Europe a lot easier, where many systems I've encountered won't work on some non-EMV cards.
I have a Tera-butte-ton of security data that I could use hadoop for analysis. Have you a free cluster?
Back in college around '08 my friend and I always used to joke that Google would buy a startup or company, then make their product free and better.

That doesn't seem to happen much anymore.
That's why this decision is about a million times better than the settlement that was shot down years(!) ago. The settlement would have given Google a monopoly on the digitization of orphan books. A ruling sets a precedent that anyone can cite.
For a view on another part of the world, just in 2012 in Japan it seemed like about nobody knew about these. Some stores didn't even know they had a pad for entering a PIN, and some didn't know what was the "enter secret code" instruction.

I only understood that after a week and maybe ten or so places had told me "your card doesn't work", when some hotel tenant called her daughter to translate things, and she knew about chip and pin and was excited to see how it worked.

I'm pretty sure all the other places just saw some message they didn't really understand, and just thought "the card doesn't work", when in fact they probably just had a pad somewhere that was waiting for my input.

Just before that, we had stayed in Taiwan and used the same card pretty much everywhere with absolutely no problem.
I have a website built with ruby on rails which I was hoping could be converted to a webservice. I would really like to use Ruby on Rails so that the website can be used as an html front end and webserive simultaneously (if this is good practice).

I'll take a look a phonegap. That name seems to be popping up a lot in google searches.
not yet, I've still some work to do. One question: do you think that Optimum-Path Forests could be used also in the context of deep learning?
* Dart doesn't require "wrappers" or classes for anything, including hello world or Fibonacci. This has been pointed out in almost every comment where you've brought it up. Yes, the examples might be confusing here, and so for pointing that out thanks and I will bring it up with the team, but repeating the claim that Dart requires wrapper classes for functions is completely unnecessary at this point.

* Most of the popular languages use braces for blocks. I sort of like significant whitespace, but it brings a lot of other problems. In the end braces are a pragmatic choice and have very little bearing on the utility or usability of a language.

* Dart also has a default visibility: public. You change it to private by adding a leading underscore.
Silicon Valley Tech Venture Capital Almanac
For most maladies, the treatment is some combination of pharmaceuticals, lifestyle changes, or diet changes. The latter two can be undertaken anywhere, so that leaves pharma.

Name-brand pharmaceuticals are expensive, but in almost all cases, there are less expensive options available that are almost as good. Most of these are off-patent, can be manufactured anywhere on earth, and can be acquired for pennies.

An intelligent diagnostic / treatment computer would know where the patient was located, their access to medical facilities, their access to drugs, and make a recommendation based on those qualifiers.
Think about cassette tapes and this devices that enable you to play your iPhone through a cassette player in your car.
I know that the processing at the one store I work at requires that we input the last four of the card. There's no way to over ride this on our end.
Yeah, actually after I made the comment I realize that that issue of acceptance is probably the reason they are selling this on kickstarter instead of a VC backing it. It may have been identified as a risk during YC and now they are still trying to make it work.

I hope the founder comments on this point. If it is usable and merchant contracts are in place for long enough, this is really cool. If there is a whole in the legal side, this feels like something that may not be ideal to back on kickstarter.
As far as I know, EMV has no way for the user (or bank's employees, for that matter) to get that private key out of the chip card; if it was possible then the whole concept would be pretty much useless and allow easy cloning of those cards just like the old magstripes.

The system doesn't allow to "trust other hardware", the card itself has to sign every transaction.
Yeah, they probably didn't think about that.
The bacteria evolving to go dormant reminds me scale insects that damaged citrus fruits. The farmers put a giant tent over every tree and gassed them. This worked at first, but after a few years the scale insects got resistant. Whenever startled, they would sit perfectly still and hold their breath for half an hour.
So really, the answer is to use payment details as user information.

That seems like a great idea. /s
I think it says that email.parser reads the whole message then parses. Flanker can just read the headers and ignore the message, so I guess with the right configuration and test data you get the 20x speed up.

It's pretty unlikely that many well-used and years old OSS language libraries have orders of magnitude speed ups lying on the table, without there being a design decision in there that can be argued many different ways.

OP here! This is not the only drop shipping site I run, and I talk about the others on my blog. This specific site (TrollingMotors.net) doesn't make six figures annually - that's correct. But I do have stores that do (I mention my other stores on my blog). And, of course, the combined earnings are above the six-figure mark.

Also, I don't sell my eBook - I give it away for free. :-)

I've only ever used S3, but some of these AWS offerings do look interesting for my little projects. My question is, how do hours get calculated for billing? If I had my super low traffic blog using RDS, would I incur a few microseconds of time per DB hit, or is it rounded up to an hour, or is it the total time the DB is available period?
And you're continuing to post links to the same domain? Brave sir, very brave.

You give the merchant your card, not your phone.
It deactivates completely when it's been away from your phone for a certain amount of time, which you can set in the settings.

Meaning shifted entirely to the consumer?
The DevShare program is the offers-based installer that's been pretty controversial in the open source community and has been discussed here previously (FileZilla bundling with their installer, GIMP Windows leaving SourceForge over it). Today, SourceForge has announced that they are re-evaluating and re-working the program and are suspending it with the current 3 members. In other words, it will remain running with those 3 members (FileZilla and 2 others I'm unsure of) but not accept new members until it's relaunched.

SourceForge also put out a call to folks to report misleading ads on the SourceForge site (fake download buttons, etc) with screenshots to blockthis@sourceforge.net so they can address them. These types of ads are the other reason GIMP pulled their Windows builds from SourceForge.

I thought the Hacker News community would be interested in this development.

Full disclosure: I run PortableApps.com, one of the largest projects on SourceForge. We do not participate in the DevShare program (PortableApps.com Format forbids add-on offers in our installer) but do participate in the SourceForge Accelerator Program which shares a percentage of ad revenue with hosters who use the SourceForge download buttons.

Always email if you feel you have been banned. A few months ago, I posted something stupid and was down voted. Almost right afterwards, the site became extremely slow but was fast when I was logged out. I thought I had been slow banned. After emailing, I was reassured my account was fine and the slowness was caused by garbage collection & caching issues.
A lot of cards also moving towards a smart chip implementations on cards. Also I carry 3 cards with me, 2 CC and a debit. Perhaps I am not the intended customer for this thing, I do like gadgets but my wallet is fine for now. Still a very nice idea. I would def follow up to see what happens after Summer 2014
Credit card fraud is generally not a problem in the US for consumers or the credit card companies, the two groups that would be in a position to adopt a new credit card technology. The merchants accept all the liability in the US credit card system, and they're at the mercy of the credit card company's policies, and the consumer's desire to use their card of choice or go somewhere else. As a consumer, I avoid cash-only businesses, and even tend to frequent ones that accept my card of choice (Discover) over those that only accept the cheaper cards (Visa/MC.) Businesses know this, and they're willing to accept credit cards so that they can earn most people's business.
A simple rule I go by: This brain is for processing. Not storing.
I guess I don't understand using the letter + doorman. Why don't you just have coffee with him and talk? Writing a letter is so impersonal - you don't know what he wants, what he's good at, etc. Your advice is great if he wants to do what you think he wants to do. It's not so great if he really wants to do something else completely. It just seems so much easier to say, "So, Michael - tell me what you want to do."
Or they just use lodash/underscore which takes care of it for you.
if by that you mean no gain to the financial institutions who get a cut whether fraud happens or not, they yeah. No big gain for them = not happening.
Do you still have a link to the presentation ? It sounds interesting.
So are Coins waterproof? Because my credit card is weather proof. Just curious.
I don't agree: law, political, and social constructs are also amenable to arguments from first principles.
You would be paying for 24 hours each day. You are renting a managed virtual server, and you pay for each hour this server is running in addition to usage fees for storage and IO operations when it's actually being accessed. It'd be $20-30/month to host the database for a very small blog.
Struggling typists prefer conciseness.
Hi, I guess two killer features that we think make all the difference are:

- the central place that modularity plays in the whole architecture, and

- the fact that the JavaScript VM is a first-class citizen.

While I don't doubt that you'll find things you miss from Scala (implicits, if you insist - though IMO they're generally harmful, pattern matching, maybe, or higher-order generics, perhaps), I'm sure you'll find things in Ceylon that you'll love. For example, I _know_ you're going to love the things you can do with union/intersection types. I think you'll really like how we treat null, and our approach to flow-dependent typing in general. You might also dig how the language treats tuple and function types, and how you can just naturally abstract over the arity of a function/tuple type. And you might find runtime metaprogramming with reified generics and the typesafe metamodel a whole lot of fun.

I hope that's at least half an answer...
Don't know if your personal card is an Amex or not, but my Amex is a Costco Amex and doubles as my membership card.

I'm surprised your loyalty cards aren't the smaller key ring ones. I have half a dozen on my keys and barely notice them.

I leave my AAA and Airline cards at home and pull them out when I need them for trips. Could probably do the same for your Zip Car card (unless you use the service multiple times a week or something) and other rarely used cards.

Last year my medical insurance company switched to paper cards which are much thinner and easier to deal with even if they're less sturdy. Same as my car insurance.

All that being said I still walk around with about a dozen cards in my wallet, so I can definitely sympathize. But I could probably edit out 3 or 4 right now and not really miss them.
Huh? BitFloor totally made this possible when it was around.
Aren't Visa and MC going chip-and-pin in the USA next year?
Here is a part that I don't get. Do they actually change the magnetic strip on the 'coin'? Or does it have a fixed VISA number that is tied to your ID and owned by the 'coin' company. Then they just use the coin app and the timestamp of the transaction to know which card to charge in the backend.

That would mean the company gets a log of all transactions.
That ciphersuite has the following problems:

- DHE: the way ephemeral DL-DH works in TLS is unfortunately misdesigned. The client first offers DHE-* ciphersuites, then the server sends a DL group and public key in that group. The problem arises because now the client cannot:

* reject that group as having too small a modulus to possibly meet the client's security requirements,

* reject that group because it doesn't support one that big (Java SSL stack does this -- doesn't support >1024-bit modulus DH -- and is therefore broken with some more aggressive servers when they select DHE ciphersuites),

* check that the subgroup is of a suitable size to meet the client's security requirements (I'm not sure if SSL predated the Lim Lee paper here, but certainly later SSL standards didn't bother to fix it)

- DSS: fine, but the security-performance profile is similar to RSA, with the exception that verification in DSA is much slower than RSA. That's the reason it's mostly overlooked in favour of RSA.

- AES: as mentioned in the article.

So, yes. It's about as good as other SSL-era ciphersuites; which is to say: slow, badly designed and mostly broken :)

> One of their developers was giving an informal presentation about their progress

The example wasn't an interview question. It seems like a perfectly normal question you'd ask a fellow developer in the course of working on a project.

Every time you ask a question you're making assumptions about prior experience.
But how many of the cards in your wallet could be replaced by Coin? For me it's maybe three. If it can't replace nearly all of them it seems pretty pointless to me - I'm still going to be carrying my wallet, it'll just have two fewer cards in it.

Yay? In any case, it does seem odd to build a business around something that is virtually guaranteed to be extinct in a few years time.
TotalBiscuit on the new Youtube comment system
It's not about providing service unconditionally - it's about have Reasonable (IMO) terms which don't give them license to turn you off whenever they want. I think it would be perfectly reasonable to specify they will do that if you were abusing resources, doing something illegal, being malicious, etc. - there needs to be some limits on when they get to shut me down. I can't consider it in any way reliable otherwise.

Then you can imagine how many people outside of the Bay area do the same thing. I've worked at places where I (stupidly) suggested some of their principles as solutions to systemic problems that came up, assuming that everyone would be on the same page (I mean their ideas just make sense right?) ... no way. I've gotten laughed out of the room a couple of times, wised up and am now resigned to the fact that unless I start my own company or join the founding core of a startup, I'll never get to apply those kinds of ideas unless I work in the Bay
Yeah, that's a clbuttic mistake.

"pushing comp-sci forward"

nit - The Dart team have explicitly said that they are not doing any features based on new computer science research. The Dart project is built on pragmatic engineering decisions, rather than "pushing comp-sci forward".

This is a good thing in my opinion.

Every time this comes up, somebody's got to get snooty about Kids These Days and Their Attention Spans and Facebooks and Pokeymans.

All I really want to do is read a book during takeoff and landing. Reading is still a thing mature, responsible people do, right? Thanks to ever-decreasing passenger and storage space, it can be a genuine pain to fit even a mid-size paperback into my carry-on luggage in such a way that it's easily accessible during flight, especially for big, tall folks like me. It's much easier all around if I can read a book on my phone, which I have to have with me anyway; or, for some people, a slim tablet or e-reader is an easier fit.

But no, I can't do that (yet). I have to either cram a book in there somewhere, or spend 20+ minutes with nothing to distract me from the heat and the cramps and the screaming babies but vapid seat-back magazines. I know it's not the end of the world, but it's one more frustration piled on top of an already deeply frustrating and dehumanizing experience. After paying hundreds of dollars for the privilege of getting treated like a criminal suspect and then packed into a can like a sardine, it's not unreasonable to keenly desire a little bit of comfort and distraction, is it?
I just invented something similar.

Though it only supports a maximum of 4 cards, at scale it would cost ~500x less.

I call it "penny." Here's my prototype: http://imgur.com/49auKC4
Apart from the security. Coin shows just how easy it is to skim and duplicate cards. Way more difficult with chip and pin.
This is interesting. You can just buy blank magstripe PVC cards in bulk for very cheap on Amazon. You can buy an ID printer for a couple grand. Why the need to repurpose old cards?
The other question is- if you have an offer letter from Google or YCombinator in hand, would you really want to go to Brown? At Google it will be like going to grad school except you will be better funded, working with more consistently smarter people, and you will be getting paid instead of racking up debt. As a YCombinator founder you'd basically already be in the position that a Brown computer science graduate hopes to one day get to. I like universities. I hope they figure out how to stay relevant.
