    As with all things, we have an arms race. Air defense suppression techniques have got better, but so have air defenses. Unless advances in supression techniques have far outsripped advances in air defense (unlikely), we're in the same boat and B-52s will be shot down when facing a modern military.

    The B-52 is great at bombing people back into the stone age, so long as the people were not that advanced to begin with (i.e. as long as the people can't really shoot back). This was evident even back in the Vietnam war.

    Want to bomb some insurgents in south Vietnam who don't have surface to air misses or fighter aircraft? No problem.

    Want to bomb north Vietnam, which has some fighters and reasonably good surface to air missiles? Danger!

    For example, look at operation Linebacker II, the American bombing campaign that "ended" the Vietnam War. The US used 207 B-52s, which flew 741 sorties during the operation. The North Vietnamize had 14 S-75 missile batteries distributed over their whole country. The S-75 design was about 15 years, so not super high tech even at the time. (The USSR had newer missilea, but they didn't give them to North Vietnam.) These 14 missile batteries shot down 15 B-52s. Granted, that's only a 2% loss rate per sortie, but imagine if North Vietnam had more than 14 missile batteries! Imagine that the missile batteries used modern technology rather than 1950s technology. The B52-s would be mincemeat even with more modern countermeasures. If the B-52 had a 2% loss rate in Iraq or Afghanistan, you would not be seeing the above headline.

    That's the fundamental issue with the B-52. It's not a threat to a modern and competent foe like China or even Russia. Iran just bought a bunch of modern surface to air missiles (with a ~250 mile range) from Russia, so who knows how B-52s would fare in Iran.

    Short version: The B-52 is great against people who wield AK-47s and drive around in Toyota pickup trucks. It's not clear how useful the B-52 is against a reasonably modern and competent military. I should add, rightly or wrongly, that is the logic for why the air force wants to ditch its A-10s, which fly at lower altitudes than the B-52 and are thus more vulnerable to man-portable surface to air missiles.

  8. very un KDE like on Will You Be Able To Run a Modern Desktop Environment In 2016 Without Systemd? · · Score: 1

    That's interesting. In the past, KDE has tried to make their software not dependent on linux functionality so that KDE can work in other places, like BSD and -- god help us -- Windows.

    Since I only used KDE on linux, that's kind of frustrating. E.g. KDE refused to use FUSE (Filesystem in Userspace) to access remote files because FUSE wouldn't work on all their platforms (back in 2006). Instead, KDE rolls its own remote access solution which only truly works with KDE-aware applications. In contrast, GNOME uses FUSE behind the scenes so that non-GNOME can seamlessly access the remote files.

    So, KDE refused to use FUSE because that was too linux specific (at the time) but now requires systemd? Ugh.

    I don't have a problem with systemd, and I'm all for focusing on functionality for the setups that most users actually use (e.g. Windows' lack of FUSE shouldn't stop KDE from using FUSE on Linux, BSD, etc.), but they should come up with a consistent policy for when they rely on an external dependency and when they don't.

    I don't think pilots would be able to see the laser unless the beams are _really_ close to the plane.

    If the laser beam is passing through empty space, there's no way to see it. The beam has to hit something to be visible. The atmosphere has some stuff in it, even on a clear night, which is why shining laser pointers at the sky is useful for pointing out starts. However, my guess is that the beam will only be visible to people nearly colinear with the beam and won't be like a blaster shot that's visible even if it pases far from you.

    In short if you're shining a beam more than ~20 m from a plane on a clear night, I doubt anyone would even notice it. If you get closer than 20 m, then at best, you're being seriously negligent. If the sky isn't clear, why on earth are you shining a laser into the sky?

  12. Subsidies on Rural Mississippi: The Land That the Internet Era Forgot (wired.com) · · Score: 1

    Everything is cheaper here.

    I hear this a lot, and while I'll take your word for it that it's true in practice, I'm not convinced it's true in principle. There are a lot of federal and state subsidies to rural areas -- both direct and indirect. E.g. the only reason there's any telecommunications services out there is the Universal Service Fund -- a transfer from urban/suburban to rural areas.

    I've seen it argued that the subsidies go the other way: the federal government sends more money per capita in direct subsidies to urban and suburban areas than rural areas. That ignores state subsidies (for schools, roads, etc.), but more importantly, spending per capita is not the right measure. The measure should be the ratio of government subsidies to government tax receipts from an area -- because that covers the implicit subsidies as well. I haven't seen this broken down on a country by county basis, but if you look at a state by state basis, rural states get some serious subsidies. E.g. Mississippi (the state in TFA) gets $2.34 in federal spending for every $1 it pays in tax revenue. It's $1.81 in Indiana. In contrast, it's $0.48 for New Jersey, the most densely populated state, and $0.54 in your home state. (Source) I don't know if you benefit directly from this, but you definitely benefit from others who are subsidized.

    In other words I think the cost of living in rural areas is artificially deflated, and if the federal tax code and subsidies get tweaked, there could be a "giant sucking sound" in rural parts of the country.

Young people leaving rural areas is not a problem unique to Mississippi. It's happening all over the US, largely due to economic reasons such as the increasing efficiency of agriculture requiring fewer people. (See Rural Flight.) Unfortunately, instead of seeing rural flight as a natural response to economics, some chalk rural depopulation up to incredibly dumb Agenda 21 conspiracy theories, which I'm guessing most slashdoters haven't heard of but which some state legislatures seem to take seriously.

    Yes, the Russian people support Putin, but I'm guessing that a lot of that is because he controls the media and can manufacture crises at will. In short, I think the second sentence in your quote explains the first rather than the other way around.

    Look at this plot of Putin's populairity rateing. His popularity had been slowly but steadily declining from 2008 to late 2013 -- dropping to a low of ~60% around the end of that period. What happens after that? A fortuitously timed olympics that stirred patriotism, and a manufactured Ukraine crisis to amp things up further. Putin's popularity jumped to something like 85%.

    Yes, a 60% approval rating is high by international standards but is low by the standards of a media-controlling leader with authoritarian tendencies. I don't think it's a coincidence that a manufactured crisis followed a steady decline to a 60% approval rating. Perhaps he saw what was happening, decided 60% was a lower limit on what he would tolerate, and brilliantly boosed it after that. (He got lucky with the timing of the olympics, which would have boosted his popularity above 60% on its own since Russia did so well at the olympics, but maybe he decided that boost wasn't enough or would be temporary.)

    Now, is this proof that old technology is to blame for Japan's famously stagnate economy? No, but it's telling that Japan has both 1990 technology and 1990 GDP per capita.

    No, GPS would be inaccurate to the point of being useless without accounting for relativistic effects. There are many references explaining this out there (see google), but here is one (emphasis added):

    The combination of these two relativitic effects means that the clocks on-board each satellite should tick faster than identical clocks on the ground by about 38 microseconds per day (45-7=38)! This sounds small, but the high-precision required of the GPS system requires nanosecond accuracy, and 38 microseconds is 38,000 nanoseconds. If these effects were not properly taken into account, a navigational fix based on the GPS constellation would be false after only 2 minutes, and errors in global positions would continue to accumulate at a rate of about 10 kilometers each day! The whole system would be utterly worthless for navigation in a very short time. This kind of accumulated error is akin to measuring my location while standing on my front porch in Columbus, Ohio one day, and then making the same measurement a week later and having my GPS receiver tell me that my porch and I are currently somewhere in the air kilometers away.

The answer is that the new manufacture seriously bent FDA rules: the product mentioned in the description is _not_ FDA approved. The company making the product is not a standard drug manufacturer; it is a "compounding pharmacy" -- meaning that it can skirt FDA rules by making batches of drugs for one individual at a time (not making huge batches and selling them to Wallgreen's, CVS, etc.) Since this drug is not widely used, this approach may work.
