I think there are much better reasons for not wanting to see bitcoins become ubiquitous. Bitcoins are not anonymous - they're pseudonymous. They're less private than a VISA gift card because instead of only having to worry about VISA seeing your transactions, now everyone can see them. If bitcoins become ubiquitous in the future, it won't be long before the addresses belonging to businesses that accept bitcoin are publicly catalogued. You would be able to see that this particular wallet went to the Starbucks on the corner, walked to grocery store down the street and spent $100 in groceries, fills up their gas tank at the gas station in the center of town once a week, etc. Once you buy something from a vendor that wants your name/mailing address, they can then tie your identity to your entire purchasing history for that wallet. Yeah, you can change wallets, but what average consumer is actually going to do this? Do you know anyone who carries multiple credit/debit cards expressly for the purpose of maintaining anonymity?

I would think the average criminal would be smart enough to obfuscate their tracks, but right now I think the only reason they use bitcoins is because their lack of ubiquity allows them some degree of anonymity. If they had to do their grocery shopping in bitcoin, they'd be doing their criminal activities in something else.
"If you’re going to get anywhere in learning mathematics, you need to learn to be comfortable not understanding something."

That's true of everything. It's fear and anxiety that prevents a lot of people from learning and trying new things. I keep trying to tell students or family members when they are learning to do stuff on the computer, just right click everything, just google anything you can think of, don't worry about it being perfect, don't worry about breaking anything. You have to hold back showing them the "answers" or else they become dependent.

Local development and huge databases?
Question for guys working on any data analytics projects - local development and working on features when the database we touch is huge. For some time now I have the problem of working with huge datasets in relational databases where having a local copy of such DB is simply not possible. I have a way of working around the problem by utilising either a mix of local editor and remote iPython or having some mocked data. That of course causes some problems with performance, since you can quite easily write slow code. Any ideas?

TL;DR: How to develop code when you need a huge database for work (more than 40GB)?

In a vast variety of different ways depending on dose, set and setting etc.

I understand your realisation, I do. But I'm not seeing how it would be world-changing if more people were allowed to take it because I know people whose LSD experience was (repeatedly) "sit in the corner of a nightclub with wide eyes and a grin".

Operational risk is usually managed with risk limits, reporting, dashboards. Since it is difficult to model quantitatively VaR tends not to be very applicable - except as a concept. The 1 in 200 event.

The concept of setting your risk limit at a non-lethal amount is completely valid. I don't know how bitcoin wallets work particularly, but simply having no more value stored in a hot wallet than can be tolerably lost (or a way of sharing that risk with users) in a single event seems reasonable. Then just work hard to prevent said loss since it destroys value.

Hey, don't blame XP. XP works fine. Just needs a browser that hasn't been abandoned.
When you write a class do you only have 4 methods on it? Create, Read, Update, Delete?

Just because you are unable to stop thinking in terms of classes, doesn't mean REST is flawed. REST doesn't have classes, it has resources, and they work differently.

Any GET you do to the system inherently changes it. I log you accessed the system, it often changes the way the object behaves (for example, you viewed it, it is now more popular, it now appears higher in results).

GET is not part of REST, it's part of HTTP, which is a particular implementation of a RESTful architecture. The flaws of HTTP are irrelevant to whether REST makes sense or not.

It doesn't work!

Your line is self-disproving, since you used a RESTful service to send it. The web has literally billions of services following REST. The proof that it works is shown again every time you click a link.

RESTful APIs died a long time ago, but somehow some people are hanging on to the archaic meaning of REST without really realizing that 'REST' now simply means 'API over HTTP'. The best APIs simply dropped supporting RESTful interfaces a long time ago and those crazy people who stick to it, like Google, have to contort their APIs into utter messes just to facilitate it.

Again, you've used a RESTful API to post this very message. RESTful APIs work, it's RPC with a RESTful facade which doesn't, and it can't die soon enough.
It's a very old impulse and not really limited to corporate group-think. "I'm gonna obfuscate my code and encrypt my data so nobody can STEAL my work!!!" said the programmer of previous decades, oftentimes experiencing a fit of egotistical paranoia over a relatively small personal project.

The same kind of mindset that thinks that the world would operate better if everyone used Bitcoin and trusted no-one.
"We gather all of the data you create about your life"

I don't see this being taken seriously, probably because it is impossible, because there is too many data, about too many things, and each action we take generate some "data" that can be tracked in infinitely different categories, so stop claiming that you'll do this.

what kind of business specifically was it if you don't mind me asking? Are there still low hanging fruit like that around?
I would strongly question that. We get our home delivery from Tesco or Sainsbury (depending who's annoyed us least that month). We have tried Asda. We will never do so again, given their consistent blithering incompetence at actual useful reliable home delivery. They're lovely about it, but I'd sorta rather they didn't mess up in the first place. NEVER AGAIN.

(This is deliveries out of the Enfield warehouse to E17 - perhaps you have a competent delivery area.)
Great article, thanks for the link. I like how the conclusion is that it basically doesn't matter, but by all means use what seems to be the preferred choice for the target audience and/or aesthetic considerations.

By the way, what is it with all these people (in the comments) misspelling "Arial" as "Ariel"? They don't misspell any of the other fonts (ok I saw one person write "Veranda"), is it some kind of in-joke? Or is it people that don't have Arial installed and never see the word in their font listings? (in which case I'm not too sure on their opinions about it, particularly since it requires quite the expert eye to distinguish it from the beloved Helvetica)
The basics of detecting lightning is to measure the potential difference (voltage) between the earth and the air. A simple home experiment you can do to detect it is to create Franklin bells:

http://en.wikipedia.org/wiki/Franklin_bells

http://www.instructables.com/id/Franklins-Bells/

In the case of this, instead of the higher voltage being in the sky (hence why lightning discharges down), the higher voltage is in the earth. You can measure the voltage between the bells (multimeters usually only go up to a few hundred volts, so wouldn't be enough) at various locations across a large area, and see if any anomalies come up before an earthquake :) You might get annoyed by the ringing first though...

Tupperware tends to be plastic, the BBC article doesn't really mention if they tested different container materials with the same substrate. For example, would a wooden container yield the same results with flour as the "soil"?

Their abstract mentions the use of 3 types of "soil" - organic powders, polymeric disks and glass particles. Does anyone have access to the full article to see if they repeated the experiment with differing containers?

Certainly those sorts of goals shouldn't be how engineers are judged (or worry that they'll be judged), and they should have their own KPIs. However, it's very beneficial for them to be included in the overall goals, as it can increase both their sense of purposes (why are their individual KPIs important?) and their sense of being a team (we're all working together to grow the userbase, not just the sales guys).
> If this is a phenomenon, could it used to generate electricity?

In theory yes. You could gain electricity by rubbing millions of plastic rods on cats. Whether that's an efficient way to produce electricity is a different matter: Power plants that use the power of waves exist, at least in experimental stages and they're probably much more efficient than a boat filled with flour.
Being labeled Satoshi regardless of truth is pretty much going to get you robbed, kidnapped or killed. This dude lives in this town and has $400M of untraceable currency?

The article is probably nonsense but incredibly dangerous none the less.

Several of the author's primary examples were actually companies she's continued to do business with, so they're clearly not applying this just to customers who weren't going to come back. I've certainly decided not to deal with a company again because right after the initial transaction I've gotten hit with a flood of this spam. I suspect there's one of the standard measurement issues where companies find it easier to quantify customers who've apparently come back due to this kind of marketing than to measure customers who've gotten sick of it and reduced or ceased their business with the company. It's possible to do a better job, but these companies never seem to and it might be that there's a perverse incentive for the marketers to mismeasure.

Having worked directly under the SVP of Business Intelligence & Analytics at one of the larger US-based social networks I can say from experience that it's really, really hard to get people to consider the things that are hard to measure or hard to interpret. Even in a company that's heavily analytics-driven there's a lot of magical thinking, a lot of anecdata, and a strong bias towards short term effects. Think of it as the marketing equivalent of laying off 20% of your workforce, telling everyone else to work 25% harder, and convincing Wall Street this means profits will go up and stay up.

It's easy to spot the bump in your balance sheet from lower costs and it's hard to quantify the long term costs of decreased morale, lower total productivity, most likely lower individual productivity, attrition, and inability to take advantage of opportunities.
Why Copyrighted Coffee May Cripple the Internet of Things
He may have been referring to the trailers included in DVDs and such. But here in France I think we also have piracy warnings in theatres now. As usual, the customer is the victim.
Wow so much dismissal and negativity here. I admit that some of these metrics are trivial and perhaps useless, but I think this is a looking glass into how life will be in the future. Everything in your life will be monitored and there will probably be interesting knowledge that surfaces. For example, I would like to know what foods I eat that effect my mood positively or negatively. I would like to know emergent routines that are detrimental to my health. I would like mountains of data to tell me if I am really happy in my life, and if not what I might consider doing to change that. Understanding these things for ourselves is difficult because we are completely biased and effected by short term noise. Is this service the answer? probably not - but starting somewhere is good.
> Nothing stops people from exchanging BTC in person. Nothing stops people from exchanging small low risk volumes on exchanges at a time.

Lack of technical knowledge and understanding stops most people from handling BTC safely. In order to manage risk, you need to understand the risk, and a lot of people just don't, and nobody is telling them or helping them in an accessible, understandable and reliable way.

> People who lost money on MtGox lost it because of decisions they made which they had 100% control over.

But that doesn't mean they understood them 100%. You make it sound like they intentionally threw money away. They didn't. They didn't expect this, didn't understand this was possible, not to mention likely. Had everybody known how MtGox operated, and had trustworthy experts explained what that meant, nobody would have put money in MtGox.

No person on earth can afford to understand 100% of everything he deals with. Easy, safe, reliable interfaces are vital once you move from hunting and gathering to a more complex society.

I remember reading (a long time ago) that occasionally static electricity in deserts caused headaches, which could be dispelled by earthing oneself.

I found this on Wikipedia just now (http://en.wikipedia.org/wiki/Desert#Dust_storms_and_sandstor...): "During a sandstorm, the wind-blown sand particles become electrically charged. Such electric fields, which range in size up to 80 kV/m, can produce sparks and cause interference with telecommunications equipment. They are also unpleasant for humans and can cause headaches and nausea. The electric fields are caused by collision between airborne particles and by the impacts of saltating sand grains landing on the ground. The mechanism is little understood but the particles usually have a negative charge when their diameter is under 250 μm and a positive one when they are over 500 μm."

Do you know if these phenomena are connected?

Wanna know the real reason why developers still prefer iOS over Android?
I had the same thought. The box in the photograph looks like acrylic, which has a strong triboelectric potential.

https://en.wikipedia.org/wiki/Triboelectric_effect

Here's a paper by the authors:

http://arxiv.org/abs/1307.2489

"The shear cell is nominally 125 cm × 26 cm in size, and the particles are weakly confined by either a 0.5 mm clear flexible PVC or 1.4 mm thick acrylic sheet in order to suppress out-of-plane buckling. The sheet is wiped with a damp cloth before the experiment to minimize triboelectrification."

Wrong use-case. Animated GIFs and animated PNGs were never intended for video. The analogy to still image formats is video:JPEG = web-animation:PNG. You don't save screenshots as JPGs and you don't save photos as PNGs. Same with video and web-animation, two different use-cases require two different formats.
The way these "news" sites talk about bitcoin is quite fearful and ignorant. I find it incredibly irritating.
While this is technically possible, it's much more likely they intend to use the credit line as lead generation for license sales on stock photography. If I sold stock, I would prefer that to the current situation of rampant unlicensed use.

For Bitcoin, Secure Future Might Need Oversight
There are two approaches that I would consider. The first is simply to ask: does your development work absolutely require large test data, or might it be possible to reduce the size through more precise selection? And more to the point, if such is possible, is it possible with a reasonable amount of effort? This is such a common problem that my guess is you're not the only one trying to solve it.

If the size of the data set is essential to your development, then could you set up a development database server on dedicated machine (could be an old workstation/laptop) on the local network that could act as common infrastructure for the whole team? This would only work if your application supports connection to a remote database, but it would solve the problem of externalizing the need for a database and sharing that resource among your development team rather than having each of you running a big DB locally.

Exactly. Also, it's a bit hard to determine but the container looks closed. In my mind that would provide another surface to enhance the triboelectric potential you mentioned.

Edit: Thanks for that link. Why don't they remove the triboelectric contribution altogether by using a more sensible container for obtaining reliable results?
Is there a book where each word is used only once?
There is really no compelling evidence in the article that this Satoshi Nakamoto is the inventor of Bitcoin. Regarding his stance to not discuss Bitcoin, I imagine he has already been approached by journalists (or lunatics) in the past, and I would be as reluctant.

It might be him but it requires some leap of faith to relate the love of model trains to the design of cryptocurrency.
Perhaps these sites should never have been setup. If they were valuable, someone would have noticed they had been attacked and would do something about it.
Testing A Diet App With Mechanical Turk
It's their right to stay private if they want to. What seems odd is that so many people are trying to unmask them.
Often it seems to simply be out of complete delusion about the value of what they've done. I interviewed a guy once that brought in a disk with a horribly crappy little mail client for Windows he'd written that was totally uninteresting to us.

I took one glance at the code, and it confirmed what we'd learned during the interview (he was turned down).

Yet he was terribly concerned with getting the disk back to ensure we wouldn't steal his mail client code. The interview was at Yahoo - it's not like we didn't run a vastly more complicated and advanced e-mail system. And not like there weren't dozens of open source mail clients that were far superior to what he brought in if we for some bizarre reasons should have wanted to "steal" code for a desktop mail client.
Sure, but I can turn that argument around too. If the software has to support 20 platforms, then your one platform that happens to use RPM is not any more special than the other 19. If they make RPMs they can charge your boss extra. Maybe your boss has a tight budget and chose to push the integration step to his/her own people.

> it's really neither.

Not just that, it's the most traceable currency on the planet. It's built on having every transaction fully traceable to the original source - a mined block, through every other transaction that contributed to the one in question. Traceability is a fundamental feature of bitcoins.
Not just in media.

I hear Bitcoin advocates frequently claim that government has an interest in "shutting down Bitcoin", but compared to the all-cash industry of most organized crime, Bitcoin's pseudonymity is law enforcement's dream come true. A state actor would merely have to obtain the identity of one key in a series of transactions on the blockchain, and would gain far more information than any informant could provide. Sure, mixers and other methods could obfuscate this, but it's not like 7/11 tracks serials of hundred dollar bills, so the blockchain by definition is richer source of transaction data.

Full disclosure: I believe strongly in the concept of crypto currencies and Bitcoin, but do not own any coins/alt at the moment.
