Comment Re:Wildly premature question (Score 1) 81

If we look at jet aircraft, wear depends on the airframe and the engines, and the airframe seems to be the number of pressurize/depressurize cycles as well as the running hours. Engines get swapped out routinely but when the airframe has enough stress it's time to retire the aircraft lest it suffer catastrophic failure. Rockets are different in scale (much greater stresses) but we can expect the failure points due to age to be those two, with the addition of one main rocket-specific failure point: cryogenic tanks.

How long each will be reliable can be established using ground-based environmental testing. Nobody has the numbers for Falcon 9R yet.

Weight vs. reusable life will become a design decision in rocket design.

Submission + - Is the Higgs Boson a Piece of the Matter-Antimatter Puzzle? (stanford.edu)

TaleSlinger writes: Why there's more matter than antimatter is one of the biggest questions confounding particle physicists and cosmologists, and it cuts to the heart of our own existence. In the time following the Big Bang, when the budding universe cooled enough for matter to form, most matter-antimatter particle pairs that popped into existence annihilated each other. Yet something tipped the balance in favor of matter, or we – and stars, planets, galaxies, life – would not be here.

The paper is based on a phenomenon called CP – or charge-parity – violation, the same phenomenon investigated by BaBar. CP violation means that nature treats a particle and its oppositely charged mirror-image version differently.

"Searching for CP violation at the LHC is tricky," Dolan said. "We've just started to look into the properties of the Higgs, and the experiments must be very carefully designed if we are to improve our understanding of how the Higgs behaves under different conditions.”

The theorists proposed that experimenters look for a process in which a Higgs decays into two tau particles, which are like supersized cousins of electrons, while the remainder of the energy from the original proton-proton collision sprays outward in two jets. Any mix of CP-even and CP-odd in the Higgs is revealed by the angle between the two jets.

"I wanted to add a CP violation measurement to our analysis, and what Matt, Martin and Michael proposed is the most viable avenue,” Philip Harris, a staff physicist at CERN and co-author of the paper said, adding that he's looking forward to all the data the LHC will generate when it starts up again early next year at its full design strength.

"Even with just a few months of data we can start to make real statements about the Higgs and CP violation," he said.

but blame does not fall squarely on NASA ... Given that there is so much real waste, I don't understand the need to latch on to myths like this.

Your criticisms about precision are valid. There are multiple levels of meaning, though, and for some audiences "is NASA a good mechanism for humans to explore space?" is well answered by less-precise stories like this one.

This story illustrates one example - one Mississippi Senator uses NASA as his personal coke-n-whores vehicle. "Should we be funding public agencies to explore space?" is a valid question and this gives one anecdote about how such good intentions are perverted and abused. Elon Musk doesn't build $400M towers he's not going to use to get coke-n-whores (isn't a Model S good enough for that?)

Comment Remedies (Score 2) 173

1) What are the remedies for breach of the terms of the GPLv2?

This one is easy - if there's a breach then the license is void and Copyright is the effective law. Code was copied without permission, which becomes a copyright violation, and remedies are already established for that.

GPL is entirely based on the teeth of copyright - almost every OSI license is. If you hate imaginary property then you might question your use of licenses that depend on it.

Comment Re:Why not ask the authors of the GPL Ver.2? (Score 5, Interesting) 173

So asking the creators of the GPL in this instance will get you nowhere because their opinion on the matter lacks any weight, its what the actual wording says which determines what you are beholden to.

Most prose can be interpreted in multiple ways and not every interpretation occurs to every human at every time. Courts are well aware of this, which is why they will only ever offer an Opinion about what things mean - never claiming to offer the Truth. Even SCOTUS only offers opinions.

Now, those courts will also issue orders to men with a violent streak to enforce their opinions, so effectively they are Law. But never Truth, which is why subsequent cases can overturn previous ones. This also means that Law is never Truth, only the prevailing view of the status quo of a given time.

Submission + - Neil deGrasse Tyson causes social media firestorm with tweet on aliens & hum (examiner.com)

MarkWhittington writes: Twitchy, a site that monitors interesting traffic on Twitter, took note on Sunday of a tweet by the celebrity astrophysicist Neil deGrasse Tyson over how aliens might regard humans. He tweeted, “Aliens, seeing Humans kill over land, politics, religion, & skin color, would surely ask, ‘What the f*%k is wrong with you?’” As far as can be determined, Tyson is not personally in contact with aliens and does not have any basis to suggest that they are appalled at human behavior or that they used salty language. However, his views on morally superior aliens looking down on humans seem to track with those of C.S. Lewis, a Christian apologist.

Submission + - Stem Cell Treatment to Regrow Torn Meniscus 'Very, Very Close' (healthline.com)

LesterMoore writes: In a new study, researchers put 3D model meniscus in sheep's knees. (Their joints are a lot like humans'.) The model attracted stem cells to it and supplied growth factors and eventually biodegraded. New working menisci grew and the sheep regained full mobility. Orthopedists say similar treatments for humans are "very, very close," according to one article.

Those "First Nations" killed off previous nations, so that's more revisionist bullshit.

It's really all lazy white people who don't feel like saying, "Apache", "Cherokee", "Iriquois", "Abanake", etc. - maybe because their ancestors' guilt is more apparrent with the specificity.

Any drive to collectivize those nations (not tribes) is an attempt to negate their value. Sure, they shared a common enemy but that's about it.

So Google is using its massive wealth to at least make a few small dents in the central planning quagmire that has granted all sorts of telecomm monopolies and seriously screwed up the progress of technology; everywhere Google exerts some competitive pressure the incumbents react and/or people get Google Fiber connections directly, improving their conditions, but ...

what we need more of is central planning, and less capitalistic drive to outcompete the extant market players. Sheesh - some people just can't handle cause and effect.

And if it were still a standalone company, I'd find no surprises here. But I'm not sure I'd want to go after *anything* that's under the umbrella of Blackberry right now. In Ford's shoes, I'd've probably just gone with some embedded Linux and called it a day. Unless, of course, they were able to get Blackberry to give them one of those, "You go under, we get the source code" clauses.
