Very disingenuous to post coinbase and say "no wait period" when you have to wait AT LEAST a week to get your bitcoins.
I used to use my credit card almost every day in America, but now that I'm in Japan I don't even have any credit cards. A lot of places don't accept them, so I just use cash everywhere. The one card I have is a bank card that I use to withdraw money from ATMs, mainly at 7-Eleven. I don't really like having to buy gift cards to use on Amazon, but it's just a minor annoyance.
Is it? Not sure, but the Coin team went gangbusters on the promotion and it seems to have worked great for them. I couldn't visit any social site today without someone talking about Coin. But I've a feeling that payment cards are far from a winner-take-all business.

The Protean Echo, OTOH, has been in development for some time. Thiago first gave me the demo at the Tech Brewery in Ann Arbor, MI and it blew the doors off anything we'd ever seen that was remotely similar. The form factor of the card itself — clear “Gorilla glass”, like the iPhone screen, with embedded circuits — and the whole user experience are beautiful. I just wish they'd hurry up and release it!
Thanks bruce. Yes, Linkedin is for sure the professional destination. Users are slightly hesitant to give out linkedin data, Facebook has a 5x larger userbase and people tend to fill minimal data such as job title and education, so the idea is to build and use a professional graph so as to interpret relevant information to the data and quantify it. There is some useful info such as interests, likes, groups etc which give vital information too.
The plan is to integrate all possible social sites and aggregate the professional data out of it.

The Zero Times Infinity Problem
I honestly don't even know what to say to sexist drivel like this. Since several replies to the parent have gone along the same lines of making overly generalizing misandric statements that would be rightly called out as sexist gibberish if said about women, I suppose I'll just reply to this most egregious of the lot:

Where have all the smart hackers gone who're so quick to point out that society is at fault when negative characters of overly-stereotyped women are raised? If I were to play their role -- and tacitly accept this farcical charade that men are all bluster and ego -- I'd point out that the reason that some men might be less inclined than some women to admit they don't know the answer to something is that they know that they'll be held accountable for not knowing that thing. In this stereotyped version of reality over which we all seem to be forming a merry echo-chamber, women are unlikely to be brutally admonished for being wrong or incompetent (perhaps because those around them expect no better of them, due to negative stereotypes). This gives them the freedom to admit they're wrong, or that they don't know a given thing. Men, on the other hand, will be held accountable for their lack of knowledge, making it a much riskier endeavour to admit they don't know something.

Of course, this entire commentary presupposes that this phenomenon even exists. My team (half male, half female), shows this 'desire to be seen as knowledgeable' as a corollary of age and gender combined: the oldest member of the team never says 'could you explain that to me', and always attempts to BS his way through conversations, but the younger 20-something aged male members of the team are perfectly happy to admit it when they're out of their depth. Maybe this is unique to us? I doubt it: somehow I expect that this stereotype -- much like all other common stereotypes -- is overly broad and downright moronic.
I'm honestly surprised we don't take a quarantine approach in hospitals. i.e The first sign of an infection gets you shipped out to a specialized hospital building (air gap) designed specifically to be able to keep patients in "solitary confinement" and able to be completely disinfected afterwards.

Gauntlt - Be Mean to your Code
To answer your question about rejecting the premise because I don't like the conclusion...

I actually agree with the statement "trust is a common good." The problem is, people often assume that esablishing a "common good" is something that requires self-sacrifice from individual people. That's not true in general, and certainly not true in this specific case. Why? Trust is _also_ an individual, personal good. Lying, cheating, and manipultaing people is not a viable way to live a sustainable, happy life.

So, if it's going to be said that "Trust is a common good," I just wanted to add, "... and also a personal good." That's why I said the person's point was a "bad way to look at it." Really, it's just an incomplete way to look at it and possibly misleading, given people's typical assumptions.

Anyway, thanks for the chat and it's nice to know that we have some common ground here.
The Mifi is the same thing as the baseband in your cell phone, and can even do SMS. Many of them are running Linux on the AP side now to support more advanced Wifi routing features.

If you were really paranoid, you might consider the possibility that it has a microphone or a speaker that can be treated like a microphone. (Though I don't know of any that actually have a beeping, vibrator or piezo output.)

Also, they may have some form of e911-compliant GPS receiver, though whether the RF is hooked up for it I wouldn't know.
Three orders of magnitude faster would mean 1000x faster.
You probably meant 3 times faster.
I have to say, I agree with this. You risk optimizing to early around a local max, not a global one. Primarily due to lack of priors. However, I will be the first to admit true research is seriously a different aptitude than acing a lecture course. Advanced degree candidates should certainly be screened somehow for the latter. But my gut is that this is just optimizing for grant extraction. Truly powerful work is always second fiddle to the "more money" hampster-wheel that is peer-reviewed academic research.

I regularly give apps permission to post on my wall, because almost every app will ask me before posting. In addition, the posts usually contain relevant content: spotify posts songs I listen to, goodreads posts book updates. Your app posted an advertisement to my wall without any prompting. This is so inappropriate (and speaking from experience, far from the most effective way to use your fb access), it bewilders me your startup thought this was a good idea.
Have you documented the RPCs to the modem as well?

I disagree on both counts. Actually, I find the assertions in that post callous and destructive. This cathedral that the poster is referring to never existed. Open source has never been healthier, and Github is a very big part of the reason why.
The prefetch will always take same amount of data no matter what the size of python object in question is. That leads two results. 1) You can miss if your cacheline size is less than python object size. 2) You miss if your python object is not alligned at the cacheline and comparison is with the part that is in the next cacheline side.

If these two condition apply then there is limit of 2 on speed up and increasing python object size reduces the effect of prefetch which still helps.

Another about prefetch distance I'd pick 5 based on his testing data.
1) It has no downside on current tests.
2) Due to prefetch constant size any prefetch that hurts because you pick distance of 5 instead of 3 is unlikely to have any meaningfull effect at any prefetch distance.
3) It allows some improvement in comparison speed. Like if there where JIT on python side to specialize the test.
4) It allows a nice factor of improvement on CORE execution speed relative to memory latency.
5) It allows you to handle situations of page misses better.
This is a tiring discourse, lets discuss arms and foreign policy budgets as well. I personally think that its too small a package to do anything significant scientifically, however sending the probe to Mars itself is good target practice for next time around.
Or MIPS or other isas, but still fairly powerful CPUs.
The main problem with cards, isn't necessarily the number, rather the speed. Nfc is the fastest implementation so far and both my credit and debit card have it, and I will gladly carry around an extra few millimetres in my pocket to speed up the transaction process.
With the current state of virtualization (vagrant/virtualbox for example), I have to wonder why anyone would choose cygwin. Honest question.
Which is a problem for advertisers. not to be meta, but its true. marketers want to but mindshare, and they want to make sure their pitch is not going to be taken out of context. not knowing what your pitch will look like in context is usually a non-starter for ad sales guys. Of course SnapChat may not want to deal with advertisers as that would require tracking and verification, which might put off some end users as well. That seems to leave fewer possible business models. Although they may invent something new, so lets not count them fully out.

Intelligence Officials Aim To Pre-Empt More Surveillance Leaks
Strictly speaking, I think you're right, but many people use the phrase Socratic Method to mean any interaction in which you use questions to influence someone's thinking.

Feigning ignorance (or playing dumb) can be an extremely effective tactic in this area. Start with a simple question that is almost embarrassingly simple and then angle follow-ups towards the actual problem/inconsistency/concern/whatever. You often don't even need to ask follow-up questions; overly simple questions get people thinking about their core assumptions, which is often the root of the problem. Or their answer reveals flawed core assumptions, which is equally good.
Wonderful, thank you for releasing this! I hope you guys continue to release good bits for handling email, it really is a bear. The ongoing joke in Zapier is a small library that I made called simple_imap. Well, as the story goes, it quickly became anything but simple...

Where is the python-requests for email? I will seriously buy someone as much beer they can consume in an evening if such a thing exists!

> Instead we're faced with the constant churn of semi-functional code, users working in silos and then showing up with patches well after it's too late to give them direction, animated GIFs instead of careful engineering discussion.

I've been paying attention to this stuff since around 1998, and except for the animated GIFs, this has always been the case. The difference is that we've had 15 years for the abandoned cruft to accumulate, and Google has gotten a lot better at finding it.

Oh so your bank issues a debit and credit card merged together? How does that work? This sounds fascinating.

I am from India, I have multiple cards but most because there is a surge of credit card offers in India, most banks are providing free credit cards and offers to get people signed up.

So many of those cards are just used to utilise those offers to get discounts and a certain select websites for discounts.

But I practically use my debit card, a credit card hooked to online payment services ( paypal et all ) and a backup credit card when I cross the limit of my other credit card. That's all.

One other card I use is just when dining out in which I get some % discount/cash back offers thats all.

The Alan Kay reference is from his OOPSLA'97 talk [2], where he says that he's "apologized profusely over the last 20 years for introducing the term 'object oriented'" and suggests that the Japanese notion of "Ma" or "the unseen stuff that goes between objects" as what is important.

(edit) [3] is a quote from a communication with Kay in 2003 -

"OOP to me means only messaging, local retention and protection and hiding of state-process, and extreme late-binding of all things. It can be done in Smalltalk and in LISP. There are possibly other systems in which this is possible, but I'm not aware of them."

"A Year of Drawball" is one of the most fascinating videos of collaborative social phenomena I've ever seen: http://www.youtube.com/watch?v=ovG-t_JPGB4

The mechanics are very similar to Moon, each individual user only had a tiny amount of ink on an extremely zoomed in canvas so large artworks would require co-operation from hundreds of people.
Pretty neat. Reminds me a lot of curiosity by 22 cans.

At Costco, you can only pay with American Express and at their gas station and store register, the card also doubles as a membership card, so since they don't explain how their card works I doubt that it would work for Costco.

While this comment may be a bit out of place, I thought I'd throw it in.

For any OSX users here, iTerm 2 has fantastic tmux integration. Simply launch tmux with the -CC flag (tmux -CC). iTerm 2 will open a new window for your tmux session. Tabs that are opened, split, etc. are created as tmux windows / panes and can be quickly restored upon resuming a tmux session.
The theory was attention while you're being told what to do in an emergency, not during the emergency itself.
Of course, it's great that it's compatible with existing systems.

It'd be nice if the part that's making payment is disconnected from my phone so I wouldn't have to hand over my phone to someone else. A potential short term solution would be to allow me to lock my phone with a pin and still have this work.

A lot of merchants want to see the physical card when making payment. I'd imagine many would be skeptical of something like this.

It's really nice to see all these ideas trying to crack the payment code. Keep at it!!

"smartphone app": for iOS and/or Android, I suppose. Can we trust anything that does not run on an open-source OS? Absolutely not.
Not in the "software that syncs files" sense of the word (which is of course a pretty important distinction under trademark law).
I submitted a link to this one a month ago that went nowhere; they're getting traction today because the Coin story in the morning spurred interest. Some of today's links are products announced in 2012.
I find this statement to be a bit absurd. The app is polished, looks good, easy to use, and has never once crashed on me. I'm honestly not sure what it could do better...

Fix what up exactly?
I never understood the stander-uppers either... until I got caught behind someone who took 10 minutes to get their overstuffed luggage out of the overhead locker. That's an annoying wait. These days it's a crapshoot - if I have people waiting for me, I'll be a stander-upper. Otherwise I'll sit until it's clear.
But this is preventable. In most cases, while you're waiting in line you can get out both cards and be ready to go when it's your turn to order and pay.

With Coin, you have to find the cards serially, no matter how much lead time you have.

Do you think it likely that an entire field that evolved over a period of thousands of years, has thousands of people doing the job all over the world daily, and is so common and important that there is scientific research performed on it pretty much not-stop, just missed this idea?

Yes. Perhaps not all medical people personally, but as an institution, the medical field totally did.
Stupid question. Win.
I'm...not sure I agree with most of this.

First of all, the size and scope of the hospital has very little to do with whether or not any particular room can be cleaned. The things that are "hard" to clean in rooms are features of the rooms themselves, not the number of them. For example, even small hospitals have TV remotes, soft and absorbent surfaces like mattresses, toilets, etc.

For that matter, small hospitals can't benefit from the economies of scale that allow large hospitals to have dedicated specialist cleaning teams for high risk rooms, or for that matter dedicated infection prevention staff.
There's also some research into surfaces that combat the formation of biofilms.
Payback. Risk. Magnitude. Is there really any more to it than that?
News Use across Social Media Platforms
That entire article is based on a completely wrong premise. From the first paragraph:

> With the introduction of Passbook, Apple has launched mobile payments on iOS and competing virtual payment systems, including bitcoin, must be terminated.

Except Passbook isn't mobile payments on iOS. The article was wrong then, and it's still wrong now. There seems to be no relation at all between Passbook and Bitcoin.
The interchange rate charged by the card network (Visa, MasterCard, etc) is determined by the type of card presented. Rewards cards are charged a higher fee because they're reward cards (the rate is literally called "CPS Rewards"), and that extra money ends up back with the card-issuing bank who's paying the rewards. If you head into your local convenience store and pay with a cash-back card, that store will lose a larger percentage of your transaction than if you had handed the very same cashier a basic non-rewards card.

The problem with the world isn't too many physical credit cards. It's too many lines of credit.
i couldn't help but think about this article when news broke of the 3 billion dollar snapchat offer.
That's a good way of putting it.. "we have to continue playing the game otherwise we lose."

But we didn't create it. Visa and the banks did.

Visa was able to win over so many banks by offering the highest interchange fee. Remember, card network customers are banks, not you, so they're actually competing to raise the fee that merchants pay (interchange) that gets passed back to the bank that issued the card. In a masterful example of leveraging network effects, Visa was able to come up with the highest fee that still had wide acceptance by merchants.

This pissed merchants the hell off. Theoretically it may have increased prices by 2% in general, but it's hard to say. That's part of the "genius" too, it's designed to be a small enough fee to be a rounding error that merchants just eat.

It did have one advantage for consumers: it made Visa accepted absolutely everywhere by further driving its network effects. (And Mastercard too which followed the same model.) As compared to networks like AmEx or Diner's Club, for example.

What happened then is the banks started competing with one another with reward programs. This basically took the margin out of the interchange and returned it to the consumers. But only if they "play the game" and know how to play it well.

So what we're left with is a silly game consumers have to play to get their 2% back, which merchants really hate.

This has been "fixed" through legislation in other countries. Australia for example. But guess what? They did a study and found that merchants did not lower prices. They just kept prices the same and enjoyed an extra 2% margin.
