Not production. Having pictures of yourself is fine in most western jurisdictions (US, UK, rest of Europe) though it is more problematic (or just plain stoning-is-too-good-for-you illegal) some paces elsewhere.

As soon as the image is sent though, most legislatures consider that pornographic distribution. Here in the UK for instance you could at least be prosecuted under the Obscene Publications Act.

Having such a picture of someone else is also against the letter of the relevant laws even if the subject of the image sent it to you.

Like laws covering the age of consent for explicit sexual activity (which varies between 14 and 21 depending on where you are and sometimes depending on your gender and orientation) it gets more complicated if an image crosses state borders (sender and recipient being in different states/countries). Generally speaking you would find yourself judged against the strictest of the laws involved, not the most lenient, where there is variation.

We may thank Antoine-Augustin Parmentier for his efforts convincing people to eat potatoes.

http://en.wikipedia.org/wiki/Antoine-Augustin_Parmentier

""" Parmentier therefore began a series of publicity stunts for which he remains notable today, hosting dinners at which potato dishes featured prominently and guests included luminaries such as Benjamin Franklin and Antoine Lavoisier, giving bouquets of potato blossoms to the King and Queen, and surrounding his potato patch at Sablons with armed guards to suggest valuable goods — then instructed them to accept any and all bribes from civilians and withdrawing them at night so the greedy crowd could "steal" the potatoes. (These 54 arpents of impoverished ground near Neuilly, west of Paris, had been allotted him by order of Louis XVI in 1787.[3]) """
This is a classic categorical problem for machine learning. I'm surprised so many suggestions have involved formulating some sort of clever algorithm like skin detection, colors, etc. You could certainly use one of those for a baseline, but I'd bet machine learning would out-score most human-derived algorithms.

Take a look at the scores for classifying dogs vs cats with 97% accuracy http://www.kaggle.com/c/dogs-vs-cats/leaderboard. You could use a technique of digitizing the image pixels and feeding to a learning algorithm, similar to http://www.primaryobjects.com/CMS/Article154.aspx.

I think that is unfair. Ireland chose to have a low corporate tax rate, a decision that can be motivated by many considerations. While this does create a loophole where companies try to pay corporate tax in Ireland on profits that, without careful accounting, would usually be taxable in other countries, this does not mean Ireland is in the wrong. If he is speaking in good faith, then Ireland should want to keep its low corporate tax rate, but fix the accounting rules that allow profits to be shifted from one country to another so easily. These rules are not necessarily within Ireland's control (I'm not an expert in international taxation, though I find it fascinating).

I have developed an algorithm to detect such images, based on several articles published by research teams all over the world (it's incredible to see how many teams have tried to solve this problem!).

I found out that no single technique works great. If you want an efficient algorithm, you probably have to blend different ideas and compute a "nudity score" for each image. That's at least what I do.

I'd be happy to discuss how it works. Here are a few techniques used:

- color recognition (as discussed in other comments)

- haar-wavelets to detect specific shapes (that's what Facebook and others use to detect faces for example)

- texture recognition (skin and wood may have the same colors but not the same texture)

- shape/contour recognition (machine learning of course)

- matching with a growing database of NSFW images

The algorithm is open for test here:
http://sightengine.com
It works OK right now but once version 2 is out it should really be great.

what I mean with the second sentence is that if you want to keep getting good results you have to have a critical view of the things you can improve and try to improve them.

Getting good results in one area shouldn't be an excuse to justify not being good in others.

I hope the interview doesn't sound like I'm only complaining about Germany, it's more in the hope that it improves so more companies can be created and maybe the example is followed by other european countries.
I wonder how it could work if done properly based on data such as cloud cover. One thing that annoyed me to no end on my TouchPad was the auto dimming based on ambient lighting. This would rapidly dim in and out as I sat on the bus trying to read an ebook as it would catch every shadow etc.

>By design as in, that's the only way the network could conceivably work. Each node must be able to verify that the chain is intact and valid, otherwise they would have to be trusting a third party. There's ways of obfuscating this anyway, which seem to work quite well in practise.

You can say that there's no other way the network could conceivably work, or that its possible to obfuscate the trail, but it doesn't make sense to say both.

Surely whatever scheme you have to obfuscate the trail could be built into the network? If so, why wasn't it?

According to some, even security researchers don't encrypt their e-mail.

Do you think normal people are going to take the care to obfuscate their Bitcoin transactions properly? I don't.

I'd love to hear more about that, because it goes against my own experience. (And I'll go ahead and disclaim that I'm obviously speaking anecdotally here.)

Whenever I've run into software that was developed by the US government it's generally been pretty competent. No worse, and maybe a little better, than what I'm used to seeing come out of the companies I've worked with. Certainly better than the stream of epic fails that seems to characterize what results from outsourcing to private contractors.

I really wish someone would put f.lux in a TV or receiver. Sure, it's not ideal for critical viewing, but it'd be great for casual tv watching/gaming at night. Anyone found good solutions for that? I tried amber glasses but it's a bit of an awkward solution and somehow doesn't feel as effective as f.lux.

Would lowering the blue light in the TV's picture settings and the brightness accomplish everything f.lux does?
Probably not great in the office, but having a nice craft beer shouldn't be discouraged - it opens up the thoughts, creates an aura of relaxation and can promote conversation and creative collaboration pretty damn fast. Not everything must be productive, productive, productive all of the damn time. Creative thoughts are an important part of the ability to execute them. Just relax and have a beer every now and then.
Stand-out quote for me:

"I was once in New York, and I listened to a talk about the building of private prisons – a huge growth industry in America. The prison industry needs to plan its future growth – how many cells are they going to need? How many prisoners are there going to be, 15 years from now? And they found they could predict it very easily, using a pretty simple algorithm, based on asking what percentage of 10 and 11-year-olds couldn't read. And certainly couldn't read for pleasure.

It's not one to one: you can't say that a literate society has no criminality. But there are very real correlations."

The OA actually seems to be claiming that it still sucks compared to Outlook. But this is similar in spirit to the endless refrain about how ill-suited the web is to application development and how far it is behind 20-year-old GUI SDKs. Meanwhile web application development continues to evolve and plow forward despite the misgivings of no small number of graybeards frantically waving their arms in protest.

The bottom line is web is two steps backwards in terms of GUI, but four steps forward in terms of distribution, cross-platform, accessibility and availability. Gmail was probably the single most important bellwether of how Microsoft's lunch would eventually be eaten by cloud services.
Try using a metronome then. I'm sure there's plenty of apps available for that.
The studies most often cited to support this finding are studies of London bus drivers vs conductors (ticket takers) on the double decker London busses. They tend to be from similar socioeconomic backgrounds, start at similar young ages, and so on, controlling for many confounding factors, but the drivers spend all day sitting, while the conductors spent most of the day on their feet.

However, when trying to find the actual study to see if they had controlled for any pre-existing conditions, I found this paper: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1008580/pdf/brji... which seems to indicate that in fact, people of heavier builds were more likely to become drivers than conductors, and conductors with heavier builds were more likely to switch to becoming drivers.

So actually, it seems that the original study may be flawed, in the way you describe. While it did study people from a young and healthy age, it hadn't considered pre-existing weight or genetic differences between drivers and conductors, and it looks like that may actually play a substantial role in the difference in findings.

The NSA's New Codebreakers
You are correct and I'm not saying that I described the Holy Grail of detecting porn in a single paragraph. I'm just pointing to another direction. No solution to a very complex problem could be one-dimensional. Combining several different tests might lead to a solution. I.e. these jujitsu photos should not even be detected as “certain body configurations” as people there are fully clothed and there's not much actual bodies seen in the picture (so mentioned skin color definitely should come to play when detecting wether you see a body or not).

At the end of the day I doubt there could be a fully bulletproof and always correct solution using current state of tech. But you need to factor much more than just skin color if you try to build an automated solution to this problem.

We do use Git for scientific papers internally. Especially in the proof reading stage we find it is the only manageable way to have multiple people provide constructive feedback to a paper in a limited time frame.

This has caught on with almost everyone (technically minded I should add) who has been exposed to the approach, so I wouldn't be surprised if this started to catch on in the wider field of Scientific publishing and Conference calls.
Same. I can't see any reason to explore whatever Delicious became after the neglect of the Yahoo years.

Even if Delicious advertised themselves as "exactly what we used to be!" I'd still stay with pinboard, because pinboard boils it down to an excellent utility. I was always struggling with Delicious to maintain my privacy settings, and it was tedious in the extreme to maintain and cull bookmarks.

And now I see in a cousin comment that pinboard has an upgrade available for a yearly fee, that archives content of bookmarked links. That makes me very happy, because it gives them revenue beyond the "one small fee for life," and makes it possible that they will outlive me.

Pinboard: it just does what it does, and very very well.
I've pretty much stopped using any bookmarking service. If something is important enough for me to remember, I file it away into one of several files (my custom categorization system).

For example, if I come across an interesting JavaScript library, I add it to javaScript libraries along with a sentence or two that gives it good context for why I should be interested, what problem it solves, etc.. Someone recommends me a movie?
I access all these files quickly through nvAlt that syncs to DropBox so I can acess from all my devices.

I found that no matter what service I was using, delicious, springpad, etc., I was only hoarding links and never really using those tools to look them back up. I was essentially "saving" them to satisfy some hoarding need or something. Often, it is just faster to do a Google search to something I remember saving, too.

I used pifilter (now WeSEE:Filter , http://corp.wesee.com/products/filter/) for a production, realtime, anonymous confession site (imeveryone.com) in 2010.

It cost, IIRC, a tenth of a cent per image URL. Rather than being based on skin tone, it was created based on algos to specifically identify labia, anuses, penises, etc. REST API: send a URL, get back a yes/no/maybe. You decided what to do with the maybes.

My experience:

- Before launch, I tested it with 4chan b as a feed, and was able to produce a mostly clean version of b with the exception of cartoon imagery.

- It could catch most of the stuff people tried to post to the site. Small breasted women (being that breasts are considered 'adult' in the US) was the only thing that would get through and wasn't a huge concern. Completely unmaintained public hair (as revealing as a black bikini) would also get through.

- Since people didn't know what I was testing with they didn't work around it (so nobody tried posting drawings or cartoons), but I imagine eg a photo of a prolapse might not trigger the anus detection as the shape would be too different.

- pifilter erred on the side of false negative, but one notable false positive: a pastrami sandwich.
So I just downloaded - why can't i figure out where TV mode is...hmmmm

When it comes to marketing what you've made, you do get the first-mover advantage but that's about all you get.

I've made many a useful, problem-solving prototype in my spare time (and even 'launched' a few of them among close friends and family) only to see the same thing going big a month later. Except, it is someone else who happens to have made the same thing a; they just manage to push it a lot better that I ever could. It also doesn't help that I'm really bad at the business side of things.

I really need to find someone who can do that for me and my ideas/prototypes... :(
