Comment Re:Dispensing our reserves? (Score 1) 255

[...] Meanwhile, engineers will continue to look at alternate cooling solutions, such as liquid hydrogen. [...]

This doesn't work. There's no viable substitute for helium, not even hydrogen. The reason helium is so useful is that it boils at 4 K (by far the coldest boiling point of any substance), remains liquid all the way down to absolute zero at standard pressure, and becomes superfluid at 2 K (the only bulk superfluid achievable on Earth).

The boiling point is important because that's how cryogenic cooling works: when you use a circulating liquid coolant, the temperature of the (coolant plus apparatus) system cannot exceed the boiling point of the coolant until the coolant has entirely boiled away, so you get a very consistent and predictable temperature (right up until the coolant is gone). 4 K is below the critical temperature of the most common materials for superconducting electromagnets: niobium-titanium (10 K, relatively cheap) and niobium-tin (18 K, highest known T_c for a traditional superconductor). Hydrogen is not a substitute, because it boils at 20 K; that's noticeably too warm for any traditional superconductor, and even if it weren't, superconductors can handle stronger magnetic fields the colder you chill them, so they'd be less useful in an MRI machine. And you can't chill hydrogen much colder than its boiling point before you hit its melting point, 14 K, at which point it stops circulating and becomes much less useful as a coolant.

The superfluidity is not quite as useful day to day, but it's used to study the behavior of other quantum mechanical systems, such as neutron star interiors, that we can't recreate in a lab. It also forms a rigorous analogy with superconductivity, especially in the case of fermionic He-3, so it gives us a chance to play with a bulk fluid that propagates fluid currents in the same way that superconductors propagate electrical currents. Nothing else can replace it for this purpose.

(Side note: helium is not a truly expendable resource. Of the helium present on Earth, not a single gram is left over from the formation of the solar system; Earth doesn't have the mass to retain helium in its atmosphere. All our helium comes from the alpha particle decay of heavier radioactive elements, like radon. When the alpha particles relax and become neutral helium gas, the gas is trapped by the same gas-impermeable rock formations that trap natural gas. However, the natural recharge rate from radioactive decay is much slower than the rate that we're extracting it and venting it, so if we don't curtail our waste we're going to run out regardless.)

Trades were executed in Chicago before the change was announced in Washington D.C. in a relativistic physics sense.

Actually, in relativistic physics sense, the trades in Chicago where outside of the light cone of the Washington event (neither in the future cone nor in the past cone). That being said, since Washington and Chicago do not move at relativistic speed with respect to each other, the trades are still at a later time than the announce, even if there's no possible causality.

But the DC announcement was not in the past light cone for the Chicago trade. Therefore the information had not yet reached the Chicago public. That is the criterion being judged, not simultaneity. Insider trading, case closed.

(And even if we take the classical limit of c approaches infinity, are we really to believe that a trade conducted within single-digit milliseconds of the announcement was based on consideration of the contents of the announcement? There exist fully automated flash trading systems hooked up to news wire services, but AFAIK even those don't react quickly enough to explain the speed of this trade. Shakier conclusion, but still insider trading.)

It does seem insane. I mean how can the court not see that this case is clearly about killing vimeo and by extension video sharing sites. How can they expect all employees to be 100% diligent. It's never going to happen. If the only option to adhere to Safe Harbor is to have google class content filter Youtube is going to be the only game in town in the US.

The legal fees alone are the killer. Veoh won every round, but had to go out of business due to the legal fees.

Maybe it's not about killing Vimeo, but rather making it "play nice" the way YouTube has: Pay for sync licensing of the music and support the licensing costs with ads.

In my experience, their primary goal in every instance is to put people out of business, if at all possible. YouTube has been 'playing nice' with them for many years, but they haven't dropped the pending case.

The blog post linked from TFS is a brief (~70 word) summary of the recent development with no links to other posts on your blog for the background on the story, only the big PDF of the decision.

The decision, IMHO, gives you what you need to know about the facts of the case in order to understand the significance of the decision. 56 pages is enough reading in my view, for our purposes. If you want more you can go on PACER and get hundreds of additional pages from the case file.

1. I don't have a paralegal to work on my blog. I do all this stuff myself.

2. The guiding principle of Recording Industry vs The People since its inception in 2005 has always been that it is designed for readers who are smart enough, and serious enough, to read the actual litigation document rather than let someone else tell them what it means.

3. The blog post doesn't link to Slashdot for "more details" it links to it for "Commentary & discussion".

4. Most Slashdotters, I have found, do read the story and litigation document... not every word, but enough to form their own opinions.

5. And no, thanks, I am not looking for you to explain to me what the decision says; I read it, and I know exactly what it says.

Submission + - Vimeo held covered by DMCA safe harbor

NewYorkCountryLawyer writes: "In a recent 56-page decision (PDF) in Capitol Records v. Vimeo, LLC, a federal court in Manhattan found Vimeo to be covered by the Digital Millenium Copyright Act, rejecting Capitol Records' arguments that it was not entitled to the statute's "safe harbor". However, Vimeo is not yet out of the woods in this particular case, as the Court found factual issues — requiring a trial — as to 10 of the videos on the question of whether they were uploaded at the direction of Vimeo users, and as to 55 of the videos whether Vimeo had actual knowledge, or red flag knowledge, as the existence of an infringement."
