It's worth pointing out that this is why we have patents. Inventors disclose how their inventions work, in exchange for a legally enforced temporary monopoly.
Interesting to see them in the same space. I wonder if someone makes the 'dark' version of this card, connected via your phone to carding networks dynamically becomes a stolen ATM card for you to get cash quickly and then deletes the data after use. Leaving you with only cash and the disguise you used to hide from the ATM camera.

Well at least that is what I think the bad guys are thinking right now.
Here is what I will suggest :

1. CSS Preprocessing Language : Any one of LESS or SASS.

2. Twitter Bootstrap or Zurb Foundation.

3. Concepts of UI/UX Design.

4. Let him do some projects and hone his skills. How about making his own website/portfolio or making some HTML templates/themes and try selling it on marketplaces like themeforest?

5. Once he becomes good at UI/UX Design & Development he can then focus on back-end. I would suggest him to go with Python & Flask. Learning Python language will not only help him in web application development but it will also allow him to explore & play other interesting stuff like Machine Learning, Computer Vision, etc.
3 and 4 were answered in their FAQ - a stronger than average electro magnet will break Coin, and Coin is automatically disabled when it's out of range of your phone.
I wonder how this will work at places that require a card to be signed. On the back of my cards, it says "Not Valid Without Authorized Signature".
To answer your first question, I gather they would be grabbing the name hard-coded in your mag stripe. Can't use multiple cards with different names.
If you just need concurrent reading and update the database from a single process, you can use CDB. It always served me well.

I would guess the answer is SSD Write Amplification. SSDs in order to write have to erase first. They also try to minimize wear so internally they spread the data around as it gets written. Maybe someone else with more experience can explain more, but that's my guess.

You are out of touch. For those < 30, SnapChat is one of the most popular social networking apps. It may not be generating revenue now, but there has to be some value in it for the amount of users it currently has.

Peer review can be pretty good for a number of things when the students doing the reviewing are reasonably competent in the material. They get more problematic as the diversity of the class increases. In my experience, they're also pretty reasonable at grading according to a well-defined and explained rubric (though in a large enough population there will be frustrating outliers). They're much less good at providing useful feedback--a point that seems to be ignored far to often in discussions about peer review.

I'm actually taking a Harvard edX course at the moment that takes an interesting approach. For part of the content (labs) what they do instead of peer grading is a self-assessment with detailed evaluation criteria. This works quite well in this instance. If you don't concern yourself with certification it makes a lot of sense to focus on what provides the best feedback.
Martini seems to be a bit more of an inclusive solution more akin to something like Revel, whereas Gorilla seems to be tackling the problem by making a number of standalone components that you can tie together yourself.

I've done a small project in both Revel and with Gorilla components and found that I actually enjoyed implementing things using Gorilla packages more, giving a great deal of flexibility and not hiding too much in the framework like Revel does.

Hi guys, I am Dhruba and I work in the Database Engineering team at Facebook. We just released RocksDB as an open source project. If anybody has any technical questions about RocksDB, please feel free to ask. Thanks.
The answer to this question is easy. Of course the universe is fundamentally deterministic. Simply look at the current state of any given system (the in this case the universe) at any given point in time. If we were to look at all of the elements of "now" could indeterminate randomness (fully or partial) account for the current state of all things in the present moment? Of course not! If we say that universe if non-deterministic, but is instead probabilistic all we are saying is that "we do not understand the system well enough to know the causal relations of all elements within the system, but we can tell you how the system as a whole will work most of the time." Probability is not different from determinism, it is simply a way of measuring outcomes for systems for which we do not or cannot have enough information about in order to understand the causal relations of all of the elements within the system.
> Some stores (particularly big box stores -- Best Buy comes to mind) always ask to see the card and ID

It seems odd that big stores would require this, since this is explicitly forbidden in the merchant agreements. Also, I've never experienced this myself in the US.

1. http://www.mastercard.us/support/problems-using-mastercard.h... "A merchant must not refuse to complete a transaction solely because a cardholder refuses to provide additional identification information."
>Make profiting from it (eg selling pictures of said actual harm) illegal.

Can't someone accused of selling child porn claim it's fake just as easily as someone simply accused of possessing it?
Care to back that statement up with any facts, sources or references? Please don't perpetuate a pseudo-science.
I'd argue though that MOOCs haven't really been disruptive. If you look at the demographics of a typical course, it's primarily people who already have degrees--and multiple degrees in many cases. So they're adult ed to a large degree. Nothing wrong with that at all. I certainly appreciate them in that vein. But it's not a disrupter of education.

I don't think this gain came from pre-fetching anything. The compiler may simply have decided to treat the entire function, or even the entire file, differently because of that one line.

I compiled (x86, GCC 4.8) lazysort.c both with and without the prefetch intrinsic, and there were substantial differences in code surrounding calls in to Python, but no change at all to the guts of the partition or sorting routines.

Regardless of what is responsible, it's not good to leave something like this in your code without really understanding what it did. There may have something else that occurred incidentally from this change, that could have lead you to a better solution.
What license did it use prior to 3.7 ?
While it's easy to get shocked at some of the author's behavior, I personally don't think it's out of the ordinary. People lie to save money or avoid blame. Examples:

- I have a friend who works at an LA Wal-Mart doing returns. You'd be blown away at the things people will bring back. My favorite is a raw turkey post-Christmas that someone didn't cook all the way.

- People lie to tech support all the time. "Oh I don't know what happened. I never logged in yesterday!" ... actually, the log file says you did.

- My sister-in-law works at a bank. The stories people will tell to fight overdraft fees are hilarious.
True. Great example.
Your business is a fringe case that you admit takes "super extra precautions", which clearly doesn't represent the majority of merchants. In fact, as a consumer I can't remember the last time a merchant took an imprint of one of my cards.

I was under the impression a lot of swipe machines used plain old phone lines. No?
So if it was such a bad idea for the women, why did they do it?

When it is better for men to do what they are told than otherwise, you classify it as a benefit. When it is better for women to do what they are told than otherwise, you call it oppression. I'm trying to draw attention to this double standard.

To be clear: neither the men nor women gained directly from having their photographs taken.
Coursera offers some phenomenal courses. If you don't like them, you can teach on Udemy, or skillshare, or a dozen other platforms. Don't b*tch just because they don't fulfill your every requirement.

Right now I'm taking a Coursera class taught by Thaddeus Hogarth. His bio does not list a PhD.

If you are not famous or educated enough to get a spot in the Coursera line up (neither am I), that is nobody's fault. Different strokes. But MOOCs are here to stay, and to revolutionize education.
Few things to help diagnose the slow transfer:

Just curious...what is the submitter's relation to Ai Weiwei and Olafur Eliasson? Is he/she their developer, or actually either Ai/Olafur? Either would be pretty cool :)
The article talks several times about this device's application in under-developed countries where 'traditional positions' are already quite common.

I guarantee you a huge percentage of the women who die every year giving birth are not 'prone and sedated'. They are (if they're lucky) in a rural clinic, with a midwife who may or may not be terribly skilled. If she _is_ skilled, it's because she has decades of experience watching mothers and babies die, and has learned many lessons in very painful ways.

This device seems to provide a means for those midwives to assist in cases where labor simply isn't progressing (and believe it or not, that still happens, despite all the 'traditional positions' in the world).
Im curious if Coin will capture my purchase data when I swipe. It's bad enough credit card companies sell my data...I am super paranoid about Coin doing the same thing.
It varies by course, so you'll need to look through the catalog. The prices are monthly, and all courses are "at your own pace", but they give an estimate for each course of how long the course will take.

Some platforms will let anyone teach. Skillshare, for example. Which is fine - you get what you pay for, and occasionally you get lucky.

Coursera and Udacity classes are (all?) taught by faculty from name-brand universities. That doesn't guarantee a great experience, but it improves your odds.
Now there's a good use for "Big Data" ;)

I'd love to see a comprehensive database of donor-politician relationships along with causes they've championed and bills introduced/voted on. In lieu of the "approval graphs" shown by TV stations during debates, it would be more productive to show their existing voting patterns and who has supported them.
Guys, seriously. Somebody built something. He's sharing it with you. Yes, there are other things that can do it.

Any replication support? (Or any sort of distribution?)
I was glossing over a detail that what the company is worth to Facebook may be different to what it is worth to the owners.

There is a little known gem of modern microeconomics called the Myerson–Satterthwaite theorem. It states that under certain assumptions (Bob knows what an item he owns is worth to him, Alice knows what it is worth to her, both values are drawn from some commonly known random distribution) there is no mechanism that will guarantee that trade takes place exactly when it "should" (when the item is worth more to Alice than to Bob) and that relies on truthful revelation by both parties.

That is, even when there is room for profitable trade, negotiations may break down because the only way to ensure the perfect outcome is for each agent to truthfully reveal what the object is worth to them, and there is no way to give people an incentive to do this in all cases.
Shaq is no slouch in terms of business savvy either.

Try keeping a secret since the widespread adoption of the Internet. Paradoxically, we now have trade secrets laws to help inventors help keep inventions secret, so they can obtain a patent, so they can reveal how the inventions work.
It already seems obsolete as it won't work with chip cards. Most POS debit and credit transactions in Canada are now done via chip-cards, so emulating a magstripe isn't helpful.

You just expressed several views with which I have no disagreement. Your original statement was:

> However, that helicopter seems ideal for antipersonnel rapid assault. Add an ounce of C4 and how could you defend against it?

I asked some pretty pointed questions about that hypothetical, and you haven't offered any rebuttal. I've also tried to explore their utility from the viewpoint of a guerrilla soldiers and a nation state.

Yes, I believe that small drones will be utilized. Yes, I believe they will be weaponized. Yes, I believe we really should do something about it! I just don't think the small ones will be weaponized in the way you're suggesting (strap on an ounce of C4 and send them in swarms). That's all.

Art is meaning, expressed. It's another matter that art isn't inherently profitable the way technology is, though.

I'm having trouble understanding your point, possibly due to my own ignorance. It sounds like an indictment against any unpopular change, which would imply society should be a pure democracy. But that seems far from desirable.

And how are 4 cards a problem?

Honest question. I also have 4 cards. They don't thicken my wallet, they weigh nothing, and.. I never had a problem pulling the one I want on first try.

I mean, even in terms of 'first world problems', turning my 4 cards into 1 would never even have occurred to me.

Replacing them with a card that will one day make me say "Sorry can't pay, looks like the battery in my CC went flat" seems outright ridiculous.

The idea is that people will anticipate that because the government is reducing deficits now, it will have less fiscal problems in the future, and therefore the individual will be less likely to be affected by higher taxes in the future or a greater fiscal crisis in the future.

The individual doesn't have to deduce this themself. The information could come second or third hand through a variety of channels.

Quantum memory 'world record' smashed
Canada already went through this. It started with the POS terminals, then gradually the cards were replaced with chip cards, then gradually the text on the terminal changed from "Swipe card" to "Swipe or Insert card".

From a consumer perspective, it was virtually painless. The biggest change is that credit card transactions now require a PIN (assuming a chip card and chip-enabled POS).
You've been around HN for 600 days as I write this so I'm surprised you've asked this question here. You should know that "open source it" was going to always be the popular answer on HN in 2013.

The 2009-2010 HN crowd was mostly startup founders, investors, and employees 1 and 2 and it was also mostly people in the US. The 2013-2014 crowd is mostly not startup founders, investors, and employees 1 and 2m and it's probably 50% US folks. As many other recent HN folks have said, "HN is just another subreddit now." That results in a very different hive mind today than in years' past.

If it was me, I'd be wary of making "business decisions" based on the answer to a popularity contest on a site mostly frequented by people who (a) don't live in my country, (b) didn't grow up in the countries I want to do business in, and (c) do not and have not ever actually owned or run a business.

The problem, of course, is figuring out whose advice to take and whose to ignore. Always tricky...
I did say existing swarm. I don't see how prosecuting downloaders as though they were uploaders makes sense either, even if they end up seeding due to the way the technology works.
It was used, so still just there. But not anymore if they finally learned why safety in design philosophy is important by paying data corruption or service break. (anyway some people never learn…)

Safety is annoying. Safer system usually generate more errors to prevent accidental mistakes. Extremely safe system prohibits even booting up the product if it's not been properly configured. It simply has much more annoying safety net. If you care the safety, this kind of annoying errors are good sign to you. But if you're newbie, this is just a big obstacle, which makes stiff learning cube.

Really. We still see many people who hate to use safety belt. Because it's annoying. And everybody did before benefits of safety belt were widely known and accepted.

Also, number of users says nothing about how well the product works. Usually, cheapest product takes biggest user-base. MySQL is cheapest to start due to lack of safety. Search this thread for the name "natural219". And see why he chose MySQL over PostgreSQL. I believe that's why most people started MySQL at first.

And surprisingly, there're so many people really don't care data safety. (maybe not that much surprise. we always see those people in TV…)

Dropshipping can be a great compliment to an existing software business, offering a nice way of increasing customer lifetime value. My wife and I develop & market CattleMax, a web app for cattle ranchers to manage their herds.

A few years ago, we were approached by a manufacturer who asked if we would become a reseller for their animal identification tags. We thought we'd try it out for a few months so we setup a store so our customers could buy from us online. Several years later, business has grown beyond just our software customers and we have launched another dropship store with another manufacturer.

The thickness of edges represents the number of times the pair of senators voted the same in the Senate (only edges above a threshold are shown).

The two tightly coiled clusters shows just how weak the relationships are between the two parties.

The closer the nodes are to the center, the more bipartisan those Senators are. In the current Congress, Sens. Murkowski and Collins really stand out as by far the most bipartisan senators and important linchpins in bridging the gap between both parties. (this bar graph of partisanship shows that: http://i.imgur.com/gYCMaxo.png)

Also, it’s clear that in the current Senate, partisanship is a lot more pronounced among Democrats, likely because they hold the majority in the Senate. (ie. they have a lot less incentive to compromise)

While there were ups and downs, it’s clear that there’s a general trend of the Senate becoming a lot more divided over the last 25 years. Comparing 1989 to today is striking — opinions were a lot more intertwined back then (this static image really emphasize it: http://i.imgur.com/4kDokyz.jpg).
