Coin is taking something that's outdated -- and unnecessarily physical, and offering a layer of digital on it to create many cards into one.

Yes, this is "doable" with existing technology, but not for the common man.

Security is going to be an issue, sure. If Kanishk can get the security tech concerns AND human worries calmed down - he's on to something that can fundamentally change how we use credit cards.

Until we realize there's really no need for a device this physical... or something beyond what we're currently carrying. But this'll require losing the magnetic strip need, and that'll take time.
I've been waiting for someone to put a name to this kind of thinking.

4 Things You Should Do To Prepare for A Hackathon
> The trouble is that some subset of the usage of P2P apps -- even for copyrighted works -- probably is fair use. Imagine some history teacher downloading Lincoln to make excerpts for classroom use in order to avoid having to personally use DeCSS on the DVD.

It seems to me the real trouble is that, with torrents, that history teacher will also be giving unauthorized copies to others, who are most likely not also history teachers.
Hey, i highly suggest getting rid of the reverse auction.

Imagine X is the highest value any bidder attaches to ownership of the site. Even if the price drops below X, the bidder has an incentive not to bid (since they can potentially wait and scoop it up at a discount). You're throwing out money.

I find it a bit unsettling that those question often center on finding out whether the universe is "in principle" deterministic. Can the universe be deterministic in principle but at the same time be indeterministic in that it is not possible to practically compute some things (because of computational complexity or other practical limitations)? Is practical and "theoretical determinism" different? Is "theoretical determinism" even a thing? Am I just being stupid, or has anybody serious already explored it?
I'm really excited about this - data streaming has been a crucial missing piece for building large-scale apps on AWS.

Great post and thanks for sharing.

How did you get started in this? I mean - why trolling motors? And, how did you find drop-ship suppliers for such a seemingly expensive/low volume-product?

Good luck!
Physical laws don't necessarily have to be deterministic.
Merchants bear the brunt of the cost of fraud. Credit card companies and consumers bear none. And as the credit card company oligopoly currently* has no viable replacement, merchants are stuck bearing the cost of fraud.

* the replacement will be when folks like Square, PayPal, etc grow large enough that merchants can replace credit card systems with them for a decent % of customers

The "make whole copies of books available" thing is crucial, because that's what makes it not a substitute for the original work. I think most companies would not be particularly upset if you torrented a demo or trailer of their movie/game/whatever. But instead, most people make the entire work available, so that it acts as a replacement for purchasing the work.
From a very quick glance at the small end the Amazon options are a little more than half the price (Ireland single AZ instance pricing and even less reserved) but multi-AZ options are probably very similar.

I don't actually know whether Heroku can failover across an AZ failure.

I'm a big fan of reasoning from first principles, but in practice it tends to work out more like 'total honesty' does with your spouse. Which is to say, not always all that great.

I tend to be a reasoned sort of guy, this doesn't mean I don't say stupid things, I do, but when called on those things I can tell you how I reasoned to them and you can help me see the error in my reasoning. When someone can't reason from such a basis, and they are insisting on some plan or assertion based on their 'gut' I find it very hard to accept that as acceptable. When they won't even talk about how one might reason to the point, I find it unacceptable.

Some people are very invested in being "right" and letting them know they may not be right is taken as an attack on their person rather than their reasoning. One of the smartest guys I met at Google had this issue. You could do ok with the Socratic Method (asking questions that might lead them to understand where they were mistaken) but even that was dangerous if done in a group context (since the audience could figure out they were wrong before they could come up with a rationale). When someone works with me to explain their reasoning I really appreciate and respect them for that.

How is this more open than just about any auction on Flippa? Basic financials and traffic stats are the norm, not a special example of transparency.
It's an economic boon, and it brings in a lot of smart people, and it makes the neighborhood more lively. All of that is awesome. I live in SOMA and believe me, I love how vibrant it is today, especially as compared to what it used to be: essentially, a dead zone of warehouses and shipping containers.

I love SF's ability to reinvent itself, to adapt its spaces, and so forth. I don't think the city gets nearly enough credit for that.

The problems are housing inventory and traffic. The city has not yet figured out a fantastic way to address either of those issues. Personally speaking, I'd freaking love a Tokyo-style mega-city of uber-high rises and elevated catwalks. I'd love for SF to become the dense, futuristic wonderland that Star Trek envisions its becoming. But a lot of regulations are in place that seem to prevent that from happening. And there's also the issue of seismic stability to contend with. SF is not exactly the sturdiest ground on which to build skyscrapers. But we need more housing, and we need more intra-city transportation that doesn't rely on the roads (which, if you've ever experienced gameday or rush-hour traffic in SOMA, you know can become hellish nightmares).

Essentially, SF is a very small space that experiences high density and is not (currently) built to accommodate such density.

All said and done, this stuff is sort of a mixed bag for me. I appreciate it in many respects, but I feel the pain in a lot of day-to-day life. It's not a binary, net-good or net-bad situation.
Until Dart is natively supported in Browsers (which might take several years, at the very least), it is going to be cross compiled to Javascript before being shipped to the end -user.

Knowing and understanding javascript and it's intricacies will be invaluable to writing and debugging good Dart code.

My favorite sentence started with: "A long time ago, the original neckbeards decided..."
For a newer web programmer learning a toolset to get things done quick is much more important than jumping on any one bandwagon. If you can't build any complex systems with what you have learned then jumping languages is not going to help you. Use what you know and build great software and when you move onto the next project you'll know where your language isn't the greatest and it's worth shopping around to know what would do it better.

Javascript is going to be around a long time, you aren't going to just wake up tomorrow and see Dart paving over everything Javascript was doing. Sticking to the beaten path when starting out, especially when the path you've chosen is ubiquitous, is not a bad way to go about things.
That is still effectively a whole copy. The law is not a poorly configured spam filter that you can get around by changing a couple of words here and there.

Because Bitcoin as a replacement for credit cards is currently just a pipe dream since less than 0.01% of people even know what it is, let alone have it. That plus its insane volatility is why it's only accepted by a handful of online merchants, mostly only for virtual goods and mostly just for show.
I am a newbie in field of Web Development, and recently I felt in love with JavaScript, especially because of the sheer capability to write Client side and Server side code in same language. Thanks to Meteor.js, it made my bond with JavaScript even more stronger.

But now with the buzz of Google Dart going around, I am afraid that, am I betting on the wrong horse? Is it the right to jump on Google Dart bandwagon? To be honest, it do looks promising.

Please guide me, what should I do, since I am a newbie, I want to take advantage of the fact that, since I don't know anything, I better learn something that have much promising future, and have an edge over technology.
Occipital Structure Sensor
Two engine planes don't have problems flying on 1 engine. Adding an engine is the best safety feature the plane can have. Multi-engine pilots often joke that you pay for both engines when you train, but you only use one, since during training, the instructors constantly shut one down. By that point, you've already got at least a single engine land certificate, so the only thing they're training you for is that when an engine cuts out, instead of gliding to the nearest field/strip, you fly there a little crooked under power.

it is possible that the MD5 hash of your partition keys isn't evenly distributed

how? i mean, apart from poisson stats / shot noise, obviously (and which is noise, so you can't predict it anyway).

thinking some more, i guess this (splitting and merging partitions in a non-generic way) is to handle when a consumer is slow for some reason. perhaps that partition is backing up because the consumer crashed.

but then why not say that, instead of postulating the people are going to have uneven hashes?

[edit:] maybe they allow duplicates?

Downside of that might be that the reverse auction probably generates more buzz though... here we are, on the front page of HN.

Seems like 20% of that slide deck is about chat rooms... GitHub still uses Campfire for chat?

I tried Campfire and Hipchat a couple years ago, neither stuck. Not sure why, maybe poor offline notifications and logging? Or maybe our team didn't have enough timezone overlap or things to chat about? Hard to say.

Is strong chat as important to Github as Zach implies?
Wow, my school's not even on the list and our graduate program for CS/CE has less than a 13% acceptance rate.
Very cool, thank you! I remembered hearing of a dropshipping guide a while ago, didn't realize that was you too.
It looks to me like a bubble. Much of the people investing in bitcoin are doing so because of hype, or at least it looks that way. Also there is no real way to short sell on bitcoins, so the market is entirely controlled by the people who are into the hype. People who are skeptical don't have much affect over the price.

However that doesn't mean bitcoins are in a bubble, for that the true value would have to be lower than what it is. And I don't know how to even roughly estimate bitcoin's true value. That is, what the price will turn out to be in the long run, what the supply and demand will be. That depends on how big the bitcoin economy will grow, and the hype, while irrational, might actually bring enough people to it to make it work. Or it might just die as people get disappointed or move onto the next thing.
> Other techniques are human-attended. Remote drones are very appealing as we've seen for most of a decade now. Anybody can afford them; its anonymous; it comes from above so is hard to anticipate.

How is a drone swarm not human-attended in a way that is distinct from existing drone weapon systems? More specifically, what advantages does a drone swarm have over existing drone weapon systems?

I still think you're missing the reason why this is a non-starter. It's not that they're ineffective (although I'd argue that they are of limited effectiveness), it's that there are too many better alternatives.

> Anybody can afford them; its anonymous; it comes from above so is hard to anticipate.

Russian 50mm mortars are inexpensive and readily available on the arms market. You can drag it through mud, drop it, and shoot it with small arms, and it will still work.

It's anonymous, because the high trajectory allows you to fire from an enclosed position, then simply walk away when you're done; remember they're cheap and available.

When you fire a mortar, it travels a long distance and comes from above, so it's hard to anticipate.

Guerilla forces love mortars. They use them all the time. They get the job done.

The SciFi-fantasty drone swarm is far too cumbersome and expensive for guerrilla forces, and it's too much of a blunt instrument for 1st-world powers.

First-world powers don't need kamikaze drones, because they can field larger, more sophisticated drones that are mounted with more advanced sensors and traditional munitions. They can fire on many targets in succession with terribly effective weaponry like a 20mm cannon. They can fire from altitude where you don't even see them. They can fly in-theater, autonomously until the time that they're needed. They can return to base, be reloaded with cheap ammunition, then return to the theater of operation.

There are some very limited scenarios where the weapon system you're proposing makes sense, but it's a tiny niche. There are too many simpler, effective options to acheive the same result. The only thing this concept has going for it is the cool factor, which doesn't count for much.
Creating Slack: The Quick Scheduling Trick To Make Your Week Most Productive
There are some theft and risk concentration concerns, along with potential feature problems (accidental card selection change), but this would be great for credit cards rewards hacking- a lot of cards have different bonus areas.. 3x-5x points/cash back on different categories, like dining, gas, groceries, travel expenses, specific department stores, etc. This would easily allow you to maximize your rewards without having to carry around all the different cards. 2x-4x extra back means this will pay for itself pretty easily.
"Reasoning from first principles: What’s the least information I need to collect from the user to make the app functional?"

Functional web apps do not need any user information.

People should be able to use the app without having to submit any contact details. An account is created for them automatically, and, presuming they like the app, they can provide contact details later.

Similarly, most apps do not require passwords at all. E-mail authentication provides a better security layer than forcing users to pick yet another (insecure) password.

The algorithm for using the site becomes:

1. System creates an account with a unique account ID if the user has no site cookie.

2. User, upon being impressed, provides e-mail and name.

3. User can sign in later using their e-mail address.

4. User receives an e-mail with a login link to click.

Most users these days will already have their e-mail application open (be it Outlook, GMail, etc.), so leveraging all the work that has gone into making e-mail secure is a win.
So only people willing to subject themselves to a goon who could, at random, accuse them of lying with no basis in fact should get security clearances?

When I start a new company project, one of the first things I do is make sure other devs can easily work on it. Encourage your tech lead to always make a script that installs and sets up necessary requirements.

Makes it very easy if you are Mac, Debian based shop --- or if you just use vagrant.

Currently this looks like:
1. Make sure we have the version of ruby we want
(if not use rvm to install)
2. Make sure our db is installed
(if not installed use brew (make sure we have brew) to install it)
3. Create our database and users on the new db server
3. Run rake db:setup

Why does it send the decryption key to the server (presuming the data is even actually encrypted server-side)? Just use the megaupload model, where you link to an address containing a #, and then client-side javascript to decrypt.

Is it perfectly secure? Of course not, but at least then this company itself can't read them. Now there's nothing NSA-resistent about it. Just NSL secretink.

Thanks for the explanation. Thankfully, I've never been a victim of financial fraud. I also do my banking with a local bank, so I have a great relationship with them. If something bad happened, I feel confident that they would take care of it quickly.
Swipe, click-to-switch, swipe, click-to-switch, swipe... Why steal one card's data when you can copy the whole wallet? :-) Or, run one card but take down the information for another.

It also appears that the Coin is programmed over Bluetooth. Why bother swiping to steal when you can run a smartphone app and take all of the cards on all of the coins in range?

If this takes off and fraud goes up, credit card companies will drop the discount vendors currently get by swiping. Maybe vendors that currently swipe will start entering CVVs? Will Coin then start storing CVVs per card?

Vendors might refuse to accept Coin in the first place (there's already a comment here from one who won't). Or credit card companies will have Coin outlawed as a counterfeiting tool. I can see how this seems like a good idea, but I don't think it will work out.
Streaming Plots with Bokeh
When I think about standing in line pressing a button, iterating through a list of all my credit, debit, and rewards cards to find the right one, it seems like a hassle. Imagine I go past the correct card in my haste and I've got to keep pressing the button until I've looped back around to the correct one. Did I screw it up a third time? Now people in line behind me and the cashier are getting pissed off with how much time I'm taking. Oh wait, that was just for the rewards card and now I have to select the payment cards? I'd be regretting my mistake and wishing I could just pull a card out of my wallet.

Looking in my wallet to pick the silver card on the middle right and the brown card on the top left is so much easier. People can pick out location and color far faster because of our evolutionary history.
I hope that you are correct! That would be great. I have experimented with Dart on both client and server and it is a nice language. Fun to develop with.
This is very cool technology but I'm skeptical for its practical usage. Lots of people have already brought up the obvious pitfalls (atm use, accidental presses, banks potentially removing card liability) but I'd also probably carry around my important cards in my wallet just in case. So they aren't really solving the problem of carrying too many cards - at least for me.

It would be useful for things like gift cards and reward cards - but is it worth it for that?
I have not seen the Carroll paper, but actually all the description in the article fully applies to the original Krussel and Smith paper, which I know very well.

One problem here is that actually, heterogeneity does not really matter much for the aggregate! In other words, the model may be more realistic, but the aggregate behavior -- such as consumption and economic growth -- tends to be relatively unaffected by inequality. This happens because of two things: (1) the poor people, exactly because they are poor, do not consume enough to create a meaningful economy-wide impact, and (2) people really hate being poor, and save more during good times so that they don't get hit with the constraints in bad times. The second one can be to some extent accounted for by allowing a sizable fraction of people to be somewhat irrational, and by getting rid of the "infinitely lived" consumers; the first would stay though. I am curious about what is exactly done in the Carroll paper to make it matter.
Agreed. This is what the SF bay should look like:
