  1. Re:Sorta plausible on Did Russia Trick Snowden Into Going To Moscow? · · Score: 1

    I think he was able to leave China because they didn't want him. They presumably had already extracted whatever information they could (if there was any). At that point he was just a liability. They didn't want to "cooperate" with the US, but at the same time didn't see any advantage in creating an incident. They had not reason not to let him go.

    Russia presumably did want him in the hopes (true or not) that he had useful intelligence information with him. They probably decided that he made a useful political playing chip as well.

    The US bungled this really badly. By to aggressively trying to retrieve Snowdon they made it clear that his allegations were largely true and attracted a huge amount of media attention. Something along the lines of "A low level NSA employee has defected to Russia. We can't comment on whether or not he had any sensitive information. He had been showing signs or stress recently. We are negotiating with the Russians for his return", followed by the traditional "no comment" on any of the issues Snowdon raised would probably have worked a lot better.

    Of course even better would to not have had the NSA act in a way that if caught would do substantial damage to US interests .

    If you think manipulating a touch screen on a bumpy road is bad, imagine trying to do it while making 6-G turns in a fighter. In turbulence I sometimes have trouble hanging onto physical knobs on my 50 year old Beechcraft.

    At SLAC we have installed real physical knobs to control the accelerator and they work. Operators can look at displays and have the tactile feedback of moving a control. It speeds up machine tuning.

    Touch screens are a way to save money, but in most cases do not improve the user interface.

    Is it a race between a Corvette and a Taurus, or is it a comparison of two different designs of battleships? I don't think the problem with the F35 is that it is a bad plane, but that it may not be a good weapon for 21st century wars.

      It might be a great weapon if China decides to invade Taiwan with thousand of troop ships, but that doesn't seem likely. Far more likely that China would use a combination of economic pressure, support of internal rebellions, cyber warfare, and possibly drones if they wanted control of Taiwan. Iraq has shown that while a technological advanced country can easily defeat the armed forces of a less advanced, less powerful country, the real difficulty is to actually extract any sort of lasting value from that victory.

    Improved weapons would not have improve the US position in Iraq, Afghanistan, Syria, or the Ukraine. War is different in the 21st century.

    It takes me 20-30 minutes to get to work by car depending on traffic. It takes an hour, with 2 changes to get there by public transit. I sometimes have to work late hours without warning - if I'm too late for the last shuttle from my workplace, I'm stuck with a $50 taxi ride.

    I work at a national lab. With overhead I cost the taxpayers something like $150/hour. Would you prefer I spend an extra hour a day working or sitting on a crowded bus? I pay taxes that help support public transportation, it just doesn't happen to serve my needs.

    Companies like Google that provide comfortable group transportation where people can work while they commute are the target of protests. Is the wealthy that are class sensitive, or it it the poor?

    That said, a bubble car wouldn't work anyway. Since I can't use it for long trips, I would be using up another very scarce parking space where I live.

  8. Re:Rinse Lather Repeat. on Misogyny, Entitlement, and Nerds · · Score: 1

    I rarely see this sort of behavior among friends because anyone who acted in a misogynistic fashion would no longer by my friend. Anyone engaging in sexist behavior at work would be fired. I expect that there are a number of people in my situation who may be aware that the problem exists but who don't see it in person, and therefor really aren't in a good position to do much about it (other than dropping friends, and firing employees who behave that way) .

    There is clearly a big problem - a quick glance at many of the posts here makes that clear. OTOH, I think it is very counterproductive to suggest that ALL or even a majority of men treat women badly. There are lots of men who are decent human beings, and lumping them in with sexist assholes, and suggesting that they are lying or naive when they say that there is minimal sexism in their environment will cause them to dismiss all claims.

    The same is true of racism - many white Americans really don't see much racism - they are there when a black man gets stop / frisked, or detained for "driving while black".

    Don't dismiss people as saying "lala I'm not involved", when they are involved by the act of refusing to associate with people who are sexist, and by maintaining a non-sexist work atmosphere. Their success in fighting sexism is that it no longer exists in their environment. Someone stuck in a sexist environment may not realize that these places exist, but they do. They aren't perfect, but they are places where women can work without being harassed, or otherwise discriminated against.

  9. Re:Ground down on Misogyny, Entitlement, and Nerds · · Score: 2

    I believe you that you have problems at your work. That shouldn't happen. One thing you can do though is to take your talent to a place where you will be treated well. Where I work (a DOE lab) there really is very little visible sexism. We have female scientists and managers, and until recently a female director. We encourage young women to start careers here through a variety of mentoring programs, though sadly not very many stay (for reasons that I think are unrelated to sexism). I'm not saying that I've never heard a sexist comment, but its really rare (I can think of only a few examples in 25 years), and the people who made them have been appropriately reprimanded.

    I'm not saying that you *should* leave your work or that it is in any way your fault or responsibility. Its just that people can only fix things within their own sphere of influence. I can do my best to make sure women are treated well here, but there really is very little I can to to see that that happens at other companies.

    There is probably a tendency for men and women who do not like sexist environments to move to better ones and that can lead to a large disparity between "good" and "bad" work environments.The people in each may have trouble believing that the other exists. In a similar way, people who are not sexist will not associate with people who are, with the unfortunate result that the lose influence over them. My friends are not visibly sexist because I won't associate with people who are.

    I think there are a lot of people who are doing the right things in environments where women are treated well. By self selection they wind up having very little contact with places where women are treated badly.

  10. Re:Wait a sec on Belief In Evolution Doesn't Measure Science Literacy · · Score: 1

    From what I've seen "law", "theory", "rule", "principal", "equation", "rule" etc are not used as rigorous terms in the scientific community. As another poster points out, Ohm's law is far less widely correct than the "theory" of gravity. Remember these are scientists, not lawyers. It is understood that any "law", "theory", etc may be invalidated by the next experiment. Its also understood that "theories" generally come with all sorts of caveats:

    The gravitational force between to bodies goes as GM1M2/r^2..... in the limit of non-relativistically weak gravity, in flat space time, over non-cosmological distances. It is understood that this has not been verified when r is small (sub millimeter), and some theories predict non 1/r^2 behavior at short distances. It is expected but not verified that M is always positive, but has not been tested for antimatter.

    Similarly the "law" of conservation of energy became the law of conservation of mass-energy (or really 4-momentum), which needs to be clarified in curved space-time. It is widely believed to be correct, but a violation of this or any other conservation "law" would be extremely interesting and is not considered impossible, though very unlikely.

    Evolution is a very complex topic. There is a huge amount of evidence to support the general concept of mutation and natural selection, but lots of missing pieces in the details. People should not "believe" in evolution. They should accept that it is a model that is widely supported and has good predictive power. Like any other theory it could be disproved by new evidence. It also does not rule out other forms of species change from Lamarkian evolution to genetic engineering.

    Maybe they meant that the switching LOSSES would be reduced by 10% - that I believe. That's a nice improvement, but a BIG difference from a 10% mileage improvement.

    Without trying to predict what Snowdon would have done in that situation, I think the mistake the NSA made was in thinking that even the foreign intelligence part of this could have been kept secret indefinitely. The Dr Strangelove quote of "you can't fault the entire system because of a single screw-up" is really appropriate. Knowledge of this program was so damaging to US business interests that the risk of an information release was too high.

    Snowdon may have acted out of (misplaced or not) morality, but when you have a secret that could move many billions of dollars from US to foreign industries, some people would have purely financial motivations to see that it was leaked.

    The job of the NSA is spying on foreign governments, I have no particular problem with that . The problem is that they did so in a way that substantially destroyed faith in US industry if / when it was discovered. All of the arguments the US government has made against using Chinese networking hardware now reflect back. If we try to claim that "everyone does it", then people will go with the cheapest vendor, and that isn't US.

    The NSA did something that if revealed would badly damage US industry. The NSA then failed to properly protect that data. Snowdon is irrelevant - with such devastating information, any proper security system had to take into account that an employee might try to release it for any of a wide variety of reasons, rational or not.
