The real difference between array and &array
This is generally known as "device fingerprinting"--there are many ways to do it but they all involve probing for unique properties of a client via JS / Flash (listing installed fonts, drawing invisible characters and measuring via JS, etc.), then hashing them together to generate a unique ID for that user.

Some people think this practice violates users' privacy, and I'm one of them. This technology can be used to uniquely identify a user across multiple logins on the same site, or even multiple sites. It's quite widespread.

This paper[0] is mostly a survey of prominent DF providers and sites using this technology, and it's also a good primer on device fingerprinting techniques.

Love it. I wanted to build something just like this in my spare time for personal use. I only made it to the timing portion.

Any plans for Android in the future?

Presumably the code is released first, then the documentation is created. It sounds like the product wasn't initially developed with the idea that it would be released to others. That doesn't make it worthless. If Twitter spent the time + money to acquire them and open-source their product, I would assume that they have a vested interest in doing more than just dumping the code on Github and ignoring it.
Pixelmator (in Vectormator mode) and iDraw are pretty amazing for my modest needs. Looking forward to seeing what else this can do.
I strongly disagree. I have three college degrees but my completion rate on MOOCs is hovering around 10% right now. Obviously I'm a sample of one, but I just wanted to give a personal account to match your own.

The classroom setting is important because it sets up social expectations and accountability. I tend to blow off MOOCs partly (there are obviously other reasons as well, including the fact that they are free) because there is no scheduled time. There is less pressure and it is up to me to make time, it isn't blocked out for me. I also get bored more easily in MOOCs because the communication only flows in one direction, from the teacher to the student. I can't ask questions or challenge assumptions during lectures. To me, that isn't as interesting, so I'm more likely to drop out.
Agreed,

MOOC don't have to replace all colleges to be wildly successful. It is enough if they become known as the best place for self-motivated, bright people to get an education. When that happens, MOOC will be the new college. That is, completion of a course of study from a MOOC provider like Udacity will be a strong signal to employers that a student is quality.

At that point, the question employers will be asking traditional students is: why didn't you do your education online where it is faster, of better quality, and much cheaper? The fact that a person needs the hand-holding and extrinsic motivation of a traditional college is not a plus.

Wanted to jump in and ask, does anyone remember a site that went through the math of two magnetic rings being charged and discharged out of sync, utilizing the delay in the speed of light between the rings to create a net force? Imagine a craft shaped like a dumbbell, with the rings where the weights are:

|---|

1...2

The idea was that you'd create a strong magnetic field in ring 1, and then the wave would travel outward both directions (one away from the ship, and one along it) and interact with ring 2, which has the opposite polarity. Ring 2 would be attracted to the magnetism from ring 1, and pull the ship to the left. Then ring 1 would turn off, and by the time the wave from ring 2 reached it, there would be no interaction. So the craft would feel a net thrust to the left. The process would repeat over and over again at high frequency, propelling the craft faster and faster.

I believe the site said the process was 25% efficient, and didn’t violate any laws of physics. The difficulty lies with hysteresis because it takes a comparatively long time to charge a magnetic field, compared to the time it takes light to span the distance. So it went off on a tangent about using lasers to charge a superconducting ring.

But I’ve always wondered if resonance could somehow be used to take the coils out of sync automatically, a bit like a tesla coil but with an imbalance the puts one ring slightly behind the other in time with respect to their frames of reference. As they move more out of phase, the net force on the coils should get stronger and stronger. This sounds similar in some ways to the the way a magnetron works, so if it can be put out of phase in a similar way, then I’m not entirely surprised by NASA’s result. If it’s true that the time delay in the speed of light can be converted to a propulsive force, then it’s going to change, well, pretty much everything about space travel. I really wish I had the link to that site.

"There's cultural incentive to report results that are favorable even if they are wrong."

Indeed, but unfortunately in western capitalism there is sometimes a financial incentive to report results that aren't favourable even if they are wrong. A bit like what happened with the banks, or with tobacco companies.

Ask HN: Pull-based work location/schedule status
Anybody know a good product or hack for tracking a team's work-from-home, start-time, and out-of-office statuses?

Right now we send emails or update the messaging system or you look at the individual's calendar.

What I want is for it to be a pull workflow - I can go see if Joe is going to be late or working from home because I care specifically about Joe's status, rather than Joe sending an email to everyone because he doesn't know who cares about his status.

Anybody know a good tool for this?
For starters, maybe we should ask why Mitro is only using 128­bit AES (stated in their PDF design doc)?

BadUSB: Big, bad USB security problems ahead
This is generally known as "device fingerprinting"

Is this definitely how it's achieved though?

I would presume a highly-skilled fraudster could just spin up a new VM, for instance, and evade detection that way.

Do we know if "regular" cookies alone are good enough for 90% of the lazy fraudsters?

Regarding using "device fingerprinting," can I collect some opinions from HN?

Specifically, if every user record created stores a fingerprint alongside it (which is only used to find account registrations from the same device) is that just as offensive as using fingerprinting to track anonymous sessions?
Thank you so much! :)

Absolutely! Started on the design, but we haven't done any programming just yet.

On the other hand, Very few people can learn math on their own; you need a gun at your head in the form of a course...

http://www.cs.indiana.edu/mit.research.how.to/section3.5.htm...

I took way more math courses than my CS degree required just because I wanted to -- so I enjoy math -- but I still benefited from the pressure exerted on me by being in a formal course. I don't believe I would have studied as deeply on my own just with the textbook, nor do I believe I would have studied as deeply with today's MOOCs.

I don't know if it was the threat of wasting tuition money, or the concern about getting a bad grade on my transcript, or the camaraderie of my in-person peers, or what, but for some topics I know good and well that the traditional college course helped me stick with learning the material.
TechCrunch Open Sources Its WordPress Async Task Library
Are there any proposals for a local CDN-like caching system capable of handling these sorts of "universal resources"?

I understand the difficulties would be many (trusted sources, versioning, etc.) but I bet it would have a huge impact on the overall web's bandwidth consumption if a page could say "load standard jQuery v1.10.2 on this page, if not cached find it here or here".

Ask HN: Do you have real-world experience of technical debt killing a project?
Explaining the impact of technical debt to someone non-technical who hasn't experienced it first hand is almost impossible (e.g. "why didn't you just do it properly the first time?").

It would be great to get a thread here detailing real-world examples of debt killing a project, or more, that we can all point people to when they claim it's just developers complaining.

Sample experiences worth sharing include:

* Have you been part of a project that ground to a halt because of technical debt?

* Have you ever had to abandon a project/product and "start again from scratch" because of problems in the previous codebase.

* Have you ever left a job because the overhead of servicing technical debt made the job impossible?

* Have you ever worked for a company that went under because debt was holding them back?

I know it may not be possible, but real company names would definitely add value.

This goes for other industries as well.

For example every insurance claim from any insurance company is run through fraud detection software. Turns out there are some characteristics of a fraudulent insurance claims that have been identified over the years. The software can flag a claim as potentially fraudulent for further human review.

Discover Card's fraud detection worked extremely well in my case. My CC number was stolen and after only two fraudulent transactions (total about $500) it tripped the software to freeze the card. I have no idea how they identified those as fraud so quickly, they didn't seem out of place to my eyes considering my transaction history.

Seth Godin talks about it as doing the opposite of what your lizard brain is telling you to do.

Writing a novel first draft
I do transcribing of old manuscripts. The first time I ran into Scribal abbreviation was on the first printing (1519) of the parallel Greek / Latin New Testament of Erasmus von Rotterdam. It turns out that many printers had taken to adopting scribal abbreviations as ligatures in order to save ink and paper.

It was very frustrating, as at that time finding information on these ligatures was difficult at best. I had to work out most of it on my own.

Iliad/Free is nice as an "agitateur", but not everything is pink int Iliad-land. Yes, they promised and delivered unlimited calls and texts, but with a launch which was relying on 90% on the main French provider (Orange) and with plenty of technical problems.

Same with their box, the launch was much smoother, but lately, there has been a lot of complaints regarding streaming rate for Youtube particularly.

In short, they have a lot of followers and supporters, who, sometimes, talk only about their brighter side and never about their darker side. Like pretty much everything else, nothing white or black.

We chose to help fund Stellar because we were very impressed with their mission and their thoughtful approach to how to get cryptocurrency into the hands of as many people as possible.

I think we all would have preferred a route that didn't require creating a new currency, but this was the best approach they could find to moving forward on their vision. Certainly the long-term hope is that the stellar will mostly help provide liquidity between other currencies, rather than become something used primarily as a first-class currency itself.

The distribution strategy here is actually something that, as far as I know, has never been tried before. It's correspondingly very difficult to know exactly how it'll turn out. The underlying motivation is to distribute the stellar as fairly and as rapidly as possible, and this model (given lots of transparency and upfrontness) was the best they could think of. (If you come up with a better one, I'd certainly love to hear it — I'm gdb@stripe.com if you'd like to talk more.)
I agree with all your specific examples. "Lying" is hard to define in gray areas (your examples arent very gray =P ) but someone has to do it. I'm glad we have those institutions as well.

Paying for jQ bandwidth is like paying for air, seriously.

With jQ, you're most likely defining the version you need, so getting upstream improvements with jQ is a bit more involved than the library simply updating itself if you aren't using the edge version.

A better argument for using a CDN is that jQ library is likely going to be cached if the user's been on the web for more than 5 minutes. Chances are, your version will be one that's cached and, instead of waiting for the downloading of a library that already exists on the users system, the library is immediately loaded and perceived PLT is decreased as a result.

There are also numerous CDNs out there, I would use a fallback stack to ping the next CDN in line as it would be a cold day if every major CDN that hosts jQ were to lose SSL support for a time.

You can track it in-browser with cookies. You can track it in-browser and have it remain when the user clears cookies with offline storage. You can track it in-browser and cross browser on the same PC and have it remain when the user clears cookies with flash cookies. When a user logs out, you can store the account fingerprint used in all 3 of those places and maintain it as another account logs in. Combine them all and it's pretty effective.
Or for that matter, why not use any of the other CDNs that host jQuery?

That sounds like the magic part. "Magically, nothing will occur." IANA physicist, but it sounds like Lenz's law might be relevant.

Well, there's the rub. It sounds like it directly violates conservation of momentum and Newton's third law.
Disagree. This movement is tantamount to saying "web developers time is worth more than your money, so throw away anything you have that does not conform to whatever the hell we're interested in as of 01JAN2018."

The world has too many millions of older devices with older browsers embedded to take this seriously. It will always be cheaper to hire web programmers willing to make shit that works than it will be to discard entire classes of device every few years.

I bet that if you actually work out what's happening, at best it's equivalent to just emitting photons, which you can do by just aiming a flashlight out the back.

"Efficiency" isn't a well-defined quantity, though. What you are looking for is thrust/power, and even a device that converts energy to photons with 100% efficiency produces preciously little thrust per power used.
