  1. She was hit here:

    I know this because I looked at

    https://www.reuters.com/articl...

    and I know the location intimately. The speed limit here is 40. The road, Mill Avenue, going northbound is two lanes plus it is adding turn lanes to go west and east. There is a bike lane. The road has just gone over a bridge (man-made lake) and under a freeway bridge (202) -- there are no off- or on-ramps at this location. There is a parking lot under the bridge for the concert venue (SW corner: visible in the Reuter's image) plus there's a public park/beach on the north side of the lake.

    As

    I haven't seen the crumpled bicycle photo, but we JUST started a bunch of "share bike" schemes in the Phoenix metro area (well, Phoenix proper has had one for while -- Tempe/Scottsdale ones are more recent): Limebike is the main one, I think (we have some that have "Ono" on them, as well). So if the bike is yellow or yellow/green, it was probably one of those. Tempe is hugely bike friendly for a US city because it is both (a) the site of ASU (b) progressive.

    The southbound lanes are 2 wide at this point, so this lady was riding a bike across ~5 lanes of traffic plus a BIG (mostly paved) median. There's a shortcut trail just RIGHT there to go east, so maybe she was aiming for that.

    A sad situation for sure. I see the Uber and Waymo vehicles all the time, so there's no lack of miles in and around that area.

  4. Rockets not a "random pick" on Neal Stephenson On Rockets and Innovation · · Score: 2

    This is the crux of it, I think:

    To employ a commonly used metaphor, our current proficiency in rocket-building is the result of a hill-climbing approach; we started at one place on the technological landscape—which must be considered a random pick, given that it was chosen for dubious reasons by a maniac

    I don't agree that Hitler choice of rocketry for the V2 was random. I think he went to his not-yet-rocket scientists and said, "How do I deliver X kilograms of payload to England with such and such circular error probability, and oh yeah, it can't be intercepted?" And rockets were the answer. And for good reasons. I'm not sure what other technologies of the 1930s and 1940s could have performed the task: submarines with huge artillery built-in (susceptible to torpedo planes unless you could do some kind of shoot and scoot); they did try the bomber thing but that wasn't a winner; balloons don't seem like a possibility. We *still* don't have something better than rockets and missiles for mass producing corpses (whether you agree its a good idea or not): perhaps the Navy's upcoming railguns are different enough to be considered a "change".

  5. Re:More Info & Dashboard on Global Warming 'Undeniable,' Report Says · · Score: 1

    Irreversible damage, to me, from a systems engineering perspective, means an unstable system or a system that trends according to a power law. No system that I can think of that involves climate or the earth behaves in that manner - rather, they all follow logarithmic or inverse power laws to trend to a steady state. And yet, somehow, you're telling me that all of the sudden we're going to see e^x where something like that hasn't existed for millions of years? Maybe there's a good reason I'm still skeptical.

    Please read up on the potential for positive feedback of carbon release through the melting of permafrost and the reduction in albedo through the melting of polar ice.

    1) Permafrost contains a lot of sunk carbon. As the arctic warms, the potential exists for this permafrost to melt and release this carbon. This will create a positive feedback that further warms the arctic, etc.

    2) As polar ice melts, the albedo (inverse of reflectiveness) of the polar seas decreases, leading to more heat being trapped (less heat being reflected into space due to lower albedo) thus warming the ocean such that polar ice melting increases. A second positive feedback cycle.

    I would describe these systems as unstable: once pushed (past some stable zone, perhaps) the effect grows: see "reverse pendulums" (regular pendulums are stable). This damage (damage defined as climate change antithetical to comfortable human existence) to is likely to be irreversible on human timescales absent some pretty awesome technology.

    I believe that I'm going to get to experience these effects first-hand. China will not get clean in time and the United States lacks the will. I don't expect to die (given current trends) until the 2060s at least. As an upper-middle class white male in the United States, the impacts on me will be more survivable than for almost anyone else on the planet, but I believe that things will get "interesting", in the Chinese sense of the word.

    I worked in defense for a number of years right out of school. As with a lot of technology companies, it is male dominated. However, the person I worked most closely with is among the first (or perhaps second) generation of female electrical engineers (in her early 50s now). She is pretty used to a male-dominated technology program. For awhile we worked on different contracts, and when she came back she said she'd hated it because there were too many women and "too much estrogen". I guess there was too much discussion and general moaning and not enough curt decision making. Or something along those lines. I guess with men there would be more yelling and anger, but ultimately progress would be made in a more timely fashion. Or so I understand her complaint.

    The only way this would not be proof is if the mechanism by which a chemical like BPA can cross the placental boundary is different in rats vs humans. Is that your contention?

  10. Re:all it has to do is damage a warhead on Critics Say US Antimissile Defense Flawed, Dangerous · · Score: 1

    Closing velocities on these impacts are in the kilometers per second range. The impulses must be tens of thousands of gees: no rocket motor imparts these velocities, nor can I imagine does reentry (otherwise the thing would decelerate to 0 within the first few feet of reentry: maybe the sideways jolting is severe...). So it seems unlikely to me that warhead designers would have incorporated sufficient ruggedness in the warhead to survive these kinds of hits. Maybe they are now.

    And of course now whatever didn't vaporize is spinning.

    And I'm sure the work to refine aimpoints hasn't ended. But with Postol it's like, "Oh my God, you missed the warhead by 1cm and only turned the missile body into plasma: what a piece of shit!".

    I think you are confused. What the grandparent comment said was correct: the budget deficit was $1.7 trillion: cutting out the roughly $700 Billion spent on defense leaves a $1 Trillion dollar deficit. That means the budget doesn't balance. Subtraction, okay? I don't understand how you think you can reduce $700 billion dollars to $350 billion (from 6x to 3x the next-biggest country's spending) and that somehow balances the budget. $1.7 trillion - $350 billion is not $0.

  13. Re:About time on Defense Chief Urges Big Cuts In Military Spending · · Score: 1

    You are wrong.

    Military spending has not "been increasing at an unsustainable rate for at least the last 30 years". In inflation-adjusted 2009 dollars, it began rising in the late 70s and peaked around '86 or so and then fell until 9/11. It's been going up since then. A slightly older web page shows a fairly similar picture as a percentage of GDP. It's just that the headline dollar number gets more and more impressive as the U.S. economy as a whole gets bigger. Compared to the rest of the world by percentage of GDP, the U.S. is 27th.

    And remember, the biggest components of the defense budget are operations, maintenance, and pay: roughly 2/3rds. About a third is procurement and R&D.

    Also remember that military spending in Europe is lower than would otherwise be the case because they offload that expense onto the citizens of the United States. The benefits associated with being the world's only military hyperpower likely makes this a worthwhile trade. Apparently the political powers of the country think so.

    Maybe I'm wrong, but it seems from a number of the documentaries and such that I've seen (less so from my personal experience) that a lot of the enlisted army is poorer, lesser educated folks trying to escape from a trying life: trying to find something better. I felt it was my duty to ensure that they always come home, that our obligation is to provide them with the tools it takes to properly execute the missions with which the American people have tasked them. I refuse to accept that we would rely on an Army in which many of us wouldn't even consider serving and then not provide them with the best that we can.

    Secondly, many appliances can *really* do with 220V (actually, it's even 230V). For example: tumble dryer, oven (electrical), washing machine, dish washer, electrical stoves and basically anything that needs to heat water. Nearly all of those are manufactured to draw about 2000-2500W maximum, which makes for a current of about 10A (at 230V). Ovens and stoves may even draw much more - induction stoves can often draw about 7000W. Good luck doing that at 110V...

    There are separate 220V circuits for these in U.S. homes. In my apartment, I know that my dryer is on a 220V circuit, and I presume the same of my electric oven and dishwasher. I don't know if these share at all. I'm pretty sure I've had the oven on while drying clothes and running the dishwasher at some point in my life (maybe just once or something...).

    I would agree that this is pretty close to the truth: innocent rich people can provide a much better defense than innocent poor people who typically cut deals. Due to the volume pressures (mostly due to incredibly minor drug offenses clogging up the courts), judges typically apply a "trial tax" where if you don't plead out, you get hit with a stiffer sentence (for taking up more of his time and lowering his "clearance rate"). Poor people who have to rely on overworked public defenders (who are also part of the court system more than private lawyers and also feel the volume pressures) are less likely to want to chance it.

    I would encourage you to read Courtroom 302 which is a look at a year in a Chicago Superior court. It's pretty disheartening. :(

    Hrm. Problems of a similar nature have been solved by the United States military in missiles. For example, look online for videos of the Evolved Sea Sparrow (oh nevermind: here ESSM). It pulls on the order of 80g when it comes hard over out of the launcher (using thrust vectoring). That video isn't the best but I don't think the better ones are public. I can't guess what the angle of attack is: call it 90 degrees... And you can still shoot this in some serious sea states and wind.

    That's a quite specific situation and I think there is a specialized at-launch autopilot, but I know that our autopilot guy for a different missile that I worked on while in defense was concerned with tail winds and head winds and these things rapidly changing (gusting). We ended up having to add static pressure ports and a pitot tube to the missile to get accurate MACH readings in the face of this: when combined with the IMU (Inertial Measurement Unit) and GPS, it was sufficient.

    So, I don't know how transferrable any of this is to commercial aviation, but it was all handled by one (very, very sharp) guy for us and a veritable shitload of Matlab and Monte Carlo simulations. Too, I think the military accepts higher failure rates than commercial aviation: like a couple of missiles in every 1000 launches in the most severe conditions. I dunno what the rates are for the commercial guys but I'd think they would be lower :).

    Well, that's not quite true. If we could replace overseas oil with this product, then we would reduce carbon emissions by however much foreign oil this new fuel supplants. It would also render us safer in the sense that we have assloads of coal here in the United States. It is true that it would not be as nice as using some other source of CO2 and at the same time closing down coal powerplants. But note that the two are not mutually exclusive: if we have some other source of carbon dioxide (as apparently this pilot project does), then the coal plants could still go.

    I agree that this process could never be a net carbon sink. Maybe we could convince/engineer the algae to grow little carbon skeletons, and then we could bury them in tiny coffins when they die.

Regardless of other cultures thoughts on the basic wholesomeness of progress, it is fact that the technological progress that has been made has given us amazing powers in a short period of time, and I don't think that anyone envisions that this growth in capability will be trailing off anytime soon. So when Clark says "Apes or Angels" he isn't "placing aliens in the Great Chain of Being", he is simply stating that the TECHNOLOGICAL CAPABILITIES of aliens that are at all similar to us will either be very primitive (apelike) because they are in the pre-exponential-growth phase, or in the angel phase (far up the exponential growth curve).
