It's interesting that the references of yours that are scientific studies are all in the last 6 years (which is when I say I was more out of the loop). This is hardly "known and accepted for decades".
SPOILERS!

In all seriousness, you're giving away way too much information, please edit it away!
The part that confuses me is that 'this has been discussed before' is considered a valid answer, as opposed to say 'yes it's horribly broken and no-one is willing to fix it'. The site routinely fails to return results for links it generated just minutes before. How that is not considered a bug, on a site that represents forward thinking web development, mystifies me.
As the linked XDA developers thread explains, this is showing both 'normal' and fast-refresh mode. So the times when it is fast are the point of this video.
Well, thresholding based on colours is really as basic as it gets. Of course, a lot of the problems come from the quality of the video you're working with.

As for automated player stat tracking, it's probably not easy, but I think it is doable. Computer vision and object tracking is definitely already being applied to american football, although I'm not sure if it's being applied to the ball and players (it's being applied to the field and stadium to show scores and yard lines).

Although, there would be a lot of huge problems, such as video feed quality, the video feed itself (you probably don't want one with tv channel overlays, lots of zoomed-in shots, replays, etc., which would make it difficult to find a good feed), and probably more problems which will pop up as you try to code the program. It would probably be useful to have some kind of partnership with whatever authority in charge of match broadcasting.

Examples of improvements: pre-process the image and adjust the colour balance, etc. You can track more than just colour. Relax the colour thresholds, and include thresholds for area, density, etc. You might also want to automatically calculate the threshold values, rather than hand coding them in.

The wiki page for segmentation ( http://en.wikipedia.org/wiki/Segmentation_(image_processing) ) lists plenty of alternatives to colour thresholding too.

Since a video is just a series of images, it would make sense to use previous images to help track anything in a video. A Kalman filter ( http://en.wikipedia.org/wiki/Kalman_filter ) with condensation tracking ( http://en.wikipedia.org/wiki/Condensation_algorithm ) can statistically predict object positions and should also be able to cope with fast changes in direction. Also useful for frames where the ball disappears behind a player or something.

Stuff like image moments ( http://en.wikipedia.org/wiki/Image_moment ) can describe objects despite movement, rotation and scaling, so that would be useful if the camera zooms in/out.

I'm probably also missing out a whole bunch of more advanced vision stuff. I'm no expert, sorry.

I don't think soccernomics would be quite as useful as moneyball though, since players in soccer depend on each other way too much for individual stats to mean much, while in baseball, the players pretty much play as individuals, which is why it's so easy to track stats and compare players.

Edit: Also, to see some examples of the problem I mentioned in my previous post, the video identifies a circle inside the penalty box as the ball. And the ball is actually yellow, but that's only clear when the camera zooms in, so nothing is being detected during those shots.

I feel like I may be getting a bit too critical of the program, so apologies to the author. I really do think it's quite an awesome demo despite everything I mentioned.
Patent, shmatent. What currently exists SUCKS. How many users have to complain before someone gets a glimmer of a clue that MAYBE they should try ANYTHING ELSE.
Agreed. Looking back, my only regret is not taking more advantage of the resources I had at my disposal. Here are a few things I'd do if I were to go back...

Hopefully you're going to a school with great professors, because, in my mind, that's mostly what you pay for. I'd take full advantage of the knowledge they have. Maybe even try to develop a kind of mentor relationship that could continue outside of school and beyond.

I'd also try and get a firm grasp on what I want to do with my education. The more focused you can be in your studies, the better you can utilize your resources. There's nothing worse than leaving school and realizing that there was someone who could have been an amazing resource for you, but you didn't realize it at the time.

Third, I'd remind myself to have a good time. There truly is no experience quite like going to college. It's true that learning should be the #1 priority, but I've seen so many people breeze through college with their head stuck in a book, and I happen to think that's a shame. You'll never have another opportunity to be surrounded by such a diverse group of people doing really interesting stuff. Take advantage while you can.
People should be taught to accept mortality, instead of the opposite. We'd have a lot more happy people.

Death is natural. It happens, that's all. It's not a bad or good thing. It's just part of everything else. If you know that before hand, you don't have to "deal around it" or feel any pain.
Thanks so much for taking the time to read and comment on my article. I love the feedback and discussion!

It’s true that for many products, some feedback from random people on the bus or street can be better than no feedback. However, user studies accelerate the learning cycle for startups. As I’ve seen over and over with many startups, companies can more quickly learn much more by talking to the right people rather than just button-holing 50 random strangers. And when building products to solve problems for specific users (such as sys admins, bicyclists, travelers, kids, English-language learners, people with email overload, etc.), it seems a little risky not to talk to those users.
Hah, you're right. It's practically impossible to generate passwords in such way that they will give hashes differing by only a byte. Sorry, I see timing attacks everywhere.
Unless the US specifically has laws about not revealing passwords, all this couple have to do is claim they forgot it.

Even if that failed, the most the judge can add to their charge is contempt of court...

This is clearly a fishing expedition (unlike, allegedly, the cited border child pornography case) by government agencies AND the justice system trying to set a precedent for searches without existing hard evidence of a crime.
Just the Tegra 4 / 5 roadmap gets me excited for performance on such devices. The competition improving on Tegra by sometimes 2x. We are in for a real treat.
This is potentially fantastic. But what i'd really like to know is how does this affect the battery life-- how much more power efficient (if at all) is it than an LCD when you are scrolling or such??
It's a matter of taste, as evidenced by the success of both eInk and LCD devices on the market. For me personally, I think the improved readability is well beyond superfluous: I regularly bring my Kindle to the beach and read in direct sunlight, a feat that's not possible with other display tech right now. Plus I can bring an eInk device with me on holiday and not worry about charging it or even packing a charger is a win in convenience.

Someone pinch me when PixelQi becomes mainstream, or Samsung does something with their Liquavista purchase, or maybe when Mirasol shows up in the market.
I think storing state on servers is always a bad idea. State should be stored in a cookie in the user's browser, letting him decide when it expires.

You are confusing licensing of code and patents. You can have an implementation that is Open Source. The problem is licensing the patents and eventually having that license trickle down to "sublicensee". Usually this does not work.

So technically the code is Open Source but each distributor must get a patent license... that is restricted to redistributing binary form only.

(I deliberately did avoid the use of the word Free Software, as this actually might not be true if the code is licensed under the Free Software license GPL).
>> speak French, Italian, and Spanish...but does that even really count?

For an English speaker, French and Spanish probably should each count for about half of a language compared to learning a truly foreign language.

Adding Italian to Spanish should count for less than a half (maybe a quarter?). However, trying to maintain Italian and Spanish simultaneously is very confusing due to the strong similarity.

True.

But to be honest, the apology and climb down were pretty decent too. All too often these things are dragged out and fought tooth and nail, to nobody's benefit but the lawyers.

Which is to say, the astrology people seem to be pretty decent folks about it, not SCO-type bipedal hagfish in 3-piece suits, or Rightshaven-style copyright sharks with a business model based on IP lawsuits.

If I knew anyone who were into astrology-type things, I think I might order them something from Astrolabe, as a small reward for the good behavior in dropping the suit.

Ignoring for a moment the question of whether IP is valid as a concept: if they were misinformed that they had a case, and that their IP had been widely misappropriated without compensation, they probably thought they were in the right. And I'm not sure I can fault them for doing so, given the advice they were likely given.

Whoever gave them the bad legal advice might have led them to believe they were on to a legal jackpot. It doesn't seem to be a big, money-spinning operation, so the case might have offered the possibility of a more comfortable old age for these people.

A little extra business from appreciative tech types would help lessen the sting.
That's a cool graph. It's hard to see, but it looks like we can't say it is distinguishable from zero?

dchest answered more of the 'what' than why

the answer to the why is news.arc (what this site runs) is the pet example of Arc, which is pg's lisp dialect focused on making lisp web apps with continuation passing style

as such, the technical purity to the idea is more important than UX, as otherwise it would mean admitting that trying to implement pretty simple web app that passes around continuations like this is a fool's errand

(actually, arc and the ideas work great for rapid prototyping but just do not work well once you reach more than all but the smallest of scales)

Do you support any .NET language or just C#? I am personally looking for something that can support a lisp, there is a lisp for the .NET VM but I don't know how active the community is for it.

If you view it as 'leveling up' like others have mentioned, then you could just view this as a branching upgrade system where some choices preclude others.
This is nice, I like it. It's very simple and has a clean design. I'm not sure how they're going to make money with it since the sellers use their own PayPal accounts. Though, how else could you do it without putting your ass on the line? All you'd need is a string of bad sellers to send PayPal running for the hills.
It's called a continuation. Continuations are essentially closures being passed around to represent state (hence "fnid"), check the Wikipedia page on them for a proper, computer sciencey definition. The nature of Lisp really lends itself to continuation-based programming. Sometimes (like on HN) it's used in web applications. In the context of web applications, it's a different approach than, for example, REST/MVC. It has a few nice properties, such as easy state management. This can be very useful when a web application is an interface to a process (e.g. checkout in a web store) as opposed to CRUDA. On HN, it allows paging that "remembers" the order of things at the time you visited the first page. Reddit uses a similar mechanism. The obvious downside is that you have to keep track of all those states and if you lose them (for example because they expire), the user workflow is interrupted (hence the error message).

It's not the trendiest programming technique around these days but it's a useful tool in the toolkit of a good developer.
But it is the psychological effect of having a strong currency being substituted with a weaker currency that will lessen consumption. Economics is more of the psychology of the consumer than anything else, at least in my opinion.
I may be wrong, but it reminds me of sth called a 'health card' being needed in my country (.pl) when you are working with food. If it's true, it only proves their legal system concerning sanitary measures has way to broad categories and somehow olive-oil (food-based) falls into 'food' while running an online store falls into 'having a place where you deal with food'. Providing stool samples of shareholders is just an extreme example what happens when laws are too general and not in time with modern business models and current technology. It's easy to figure out that broad laws open to interpretation are easy to abuse by corrupted officials.

I wonder why this hasn't been a standard for maps for years. By far the most frustrating thing about road trips (pre-iPhone) used to be dragging out the map then trying to put it away again.

Also, as a total aside, this: "over their conventionally folded*" should be punishable by death. Putting an asterisk next to something then not explaining it is pure evil.
Why would a competitor build this Riak benchmark? How are they supposed to know which Riak configuration performs best?

That's the point of YCSB. Each vendor can submit the optimal configuration for their system, and they all run the same benchmark.

At the end of the day, each vendor is going to publish benchmarks that show their system performing better than all others.

It's your job, not theirs, to verify those benchmarks for your particular work load.

Edit: Also, while Mongo wouldn't classify as a distributed store, Cassandra definitely would. In fact, it's more "distributed" than Riak, since you have to pay Basho for multiple DC support (unless that's in the open source version?), whereas Cassandra is completely free.

Not a bad idea at all. I wonder though, since the buyer can file a complaint directly through PayPal if holding the payment would be enough. It would be sort of like having all credit card-paying customers initiate chargebacks when they want a refund.

Admittedly I've only recently begun using PayPal for selling so I'm still a bit unsure about how they handle some scenarios.

This is most certainly not the case here. Read this: https://www.eff.org/sites/default/files/filenode/rule11motio...

Astrolabe deliberately filed a complaint but did not serve the defendants. In a sense, they create a huge legal uncertainty which just by itself caused significant damage. This was a clear abuse of an enforcement loophole in the litigation-heavy American justice system.

The mere threat or FUD of full legal action is being used to eliminate competition. If there were ever a case for sanctions, this would definitely be it.
I'm just guessing, but it would make sense for large paper maps not to use this fold so that you can partially unfold it and look only at the portion in which your are currently interested, instead of having a giant unfolded piece of paper. This would be especially nice in a small car where you would lack room to move a completely unfolded map around.
The telephone directory is not a classic example, but there is some controversy over the copyright claims on regional building codes and WestLaw's legally-citable database of court cases.
Cavitation Reactors... Is The Future Here?
http://www.24-7pressrelease.com/press-release/nanospire-inc-successfully-harnesses-cavitation-zero-point-energy-to-produce-dramatic-levels-of-fusion-amp-transmutation-in-water-262247.php

Longer, with more details

Evidence of trenches generated by the passage of the water crystal propelled by the LeClair Effect could be seen all over the reactor cores. The positive crystal followed the induced negative charge on the rows and columns of holes of the coiled perforated aluminium plate that formed the reactor cores, with trenches usually going tangent to tangent along the holes, orbiting the holes and also the sheet edges, all guided by electrostatic attraction. Many of the holes were progressively filled with transmuted material, transmuted material also formed on the sheet surface. A uniform width melted heat affected zone (HAZ) along each side of the crystal trenches could be seen. The trench was disrupted at many points along its length by millimeter-sized pits from the apparent triggering of small supernova explosions, which also contained macroscopic amounts of multicolored transmuted elements.

The large scale transmutation of elements was verified by three separate independent scanning electron microscope elemental analysis (SEM-EDAX) of the transmuted material...

Often times hiking maps are so large that you couldn't practically unfurl the whole map. In these cases it would be great if you could easily access individual map sections.
