  1. Re:It was bound to happen sometime on Huawei Claims 30Gbps Wireless 'Beyond LTE' · · Score: 5, Insightful

    I think bandwidth (as in transfer rates) will hit diminishing returns rather soon. Once your phone can stream live HD video and audio...what's the incentive to improve? Sure, file downloads could be faster, but most people would rather just stream their content, and unless your mobile devices have terabyte hard drives in them you won't be downloading a huge amount anyway.

    I'd say once mobile devices can consistently transfer at ~10Mbps, the focus should really switch to increasing coverage and caps. All the speed in the world doesn't help if you can't get reliable service or you use up your monthly allotment in five minutes.

  2. Re:Perspective, people, perspective on Ask Slashdot: How Would Room-Temp Superconductors Affect Us? · · Score: 1

    Your calculations are off. I pointed out that (assuming a high efficiency transport mechanism) lifting every human to space would require ~1% of *proven* oil reserves. If we need 1000kg of equipment for every 1kg of human, that would only be 10 times current proven reserves. Considering oil shale alone accounts for roughly three times our proven reserves, plus the other unproven reserves, plus all the unexplored deep sea fields, and then all the coal, methane, propane, and other "fuel" sources, plus all the fuel we can generate synthetically, it's quite likely that we could find "enough fuel on earth" to bring up all the equipment as well.

    And the ISS actually makes a rather inefficient form of housing. If we were looking to build an orbiting residence for seven billion people, we wouldn't make a bunch of long metal tubes—we'd probably make a spherical structure with water and radiation-resistant gear on the outside and paper-thin walls on the inside, which would cut the mass-per-occupant dramatically.

    Since we haven't yet built a truly self-contained ecosystem here on earth, it's impossible to estimate the actual mass necessary to support human life indefinitely. And by the time we're ready to start work on such a project, we could very well end up pulling much of the resources from asteroids or the Moon. But I still think that the GGP's statement:

    I very much doubt that there is enough fuel on Earth to lift the entire population into a near-Earth orbit, not to mention the massive amounts of infrastructure required to keep them there, (and breathing).

    is quite wrong, assuming we can build an even moderately efficient transport system.

    Without doing the calculations, I very much doubt that there is enough fuel on Earth to lift the entire population into a near-Earth orbit

    Well, let's do some (back of the envelope) calculations!

    First, let's assume we build a space elevator or something like it so we aren't wasting energy on rockets. And we'll assume that we can efficiently get power to said elevator.

    Ignoring air drag (since we're presumably using an elevator), it would take about 30MJ/kg to put 1kg into low earth orbit or 50MJ/kg to lift the same weight to geosynchronous orbit. Coincidentally, this is close to the same energy contained in 1kg of oil (~42MJ/kg), though capturing that energy will not be 100% efficient. And the energy required to lift the elevator itself should be considered, though it could recover most of that energy during the trip down. Ultimately, the average ~75kg human would probably take around 2 barrels (~280kg) of crude oil to lift to geosynchronous orbit, or 1.5 barrels to put in LEO. (side note: a long flight in a 747 burns nearly 3 barrels of oil per passenger.)

    7 billion people x 2 barrels = 14 billion barrels. That's less than 1% of the current proven oil reserves.

    Of course, we'd probably want to give people a place to live once they reach orbit, but I can't really estimate the total mass of all the equipment needed to sustain the world's population. It seems feasible that between our proven oil reserves, whatever unproven reserves may exist, and the trillions of barrels tied up in shale, there's actually enough oil on the planet to see everyone off to their new life in space.

    This article came at a fitting time as I had recently picked up the bad habit of writing. It's a peculiar problem I have; it sneaks up from time to time, usually as the result of a new gadget which had the misfortune of including a keyboard. The impulse afflicts me for a few days or weeks until I finally convince myself, in no uncertain terms, that I am really a irredeemably terrible writer and should, in a just universe, have long ago been issued a restraining order against the whole of the English language. As this is, alas, an entirely unjust universe, over the years I have left a terrifying path of half-finished video game plots, reimagined TV shows and fan-fics in my wake.

    But I digress. When I stumbled upon this article I thought that it would be my rescue, as my recent purchase of a Bluetooth keyboard for my smartphone had me again fancying myself an auteur while the tiny rational part of by brain helplessly fought the controls. While I had never read any of Suzanne Collins work, surely anyone capable of penning a third of Amazon's top quotes must have a rapier wit and a stunning insight into the human condition. It would be a delightful chance to reaffirm my own incompetence and move on with my life. And I'd even get a new collection of bon mots to use at the water cooler. What could possibly go wrong?

    From TFA:

    Enrolling [in Precheck] requires a $100 application fee for a background check, plus a brief interview with a Customs officer.

    Once in Precheck, TSA still checks names against terrorism watch lists before every flight, just as it does for other travelers. If a passenger is cleared for Precheck screening, a code is embedded in a traveler's boarding pass.

    Precheck members usually get to use security lines set up for first-class and elite-level frequent fliers. But Precheck travelers actually don't know if they will get to use the easy screening until the TSA officer checking IDs actually scans the boarding pass. If the pass has the code, a Precheck passenger is steered to a separate screening lane for what amounts to old-style airport screening.

    TSA says Precheck members are selected randomly for regular screening to enhance security. But that unpredictability irks frequent travelers. The agency doesn't make travelers go to the end of the regular screening line, however, but instead slips them into the front of the regular queue.

    So it's a bit more complicated than waving a Benjamin in front of your friendly TSA employee. Though that probably works, too.

  19. I don't really agree with Ben here. on Did Benjamin Franklin Invent Daylight Saving Time? · · Score: 5, Insightful

    As the summary mentions, Ben's argument was basically that "early to bed and early to rise" saved energy. Getting up with the sun and going to sleep earlier in the evening reduced the need for lamp oil. And while we use electricity instead of lamp oil, this argument is still used today.

    However, when you consider that lighting is becoming more and more efficient and most of our personal energy consumption now goes to heating and cooling, the picture changes. Since the Earth takes time to warm and cool each day, the daily temperature cycle lags behind the sun by a few hours. Getting up early in the winter just means more energy spent heating your home and office, and working late in the day during summer means high A/C bills.

    Plus, most people want some daylight time outside the typical 8-5 work window. There's no reason to line up the work day with daylight hours; these days, most people are cooped up in office buildings and don't really care whether it's light or dark out. And commuting during sunrise or sunset is dangerous, so that's another good reason to offset the workday from the sun cycle.

    Finally, studies have shown that a period of bright light, preferably sunlight, is important for our health during the winter months. So yet again it makes no sense to align the workday with the daylight cycle, since commuters at northern latitudes only see a bit of dawn and dusk during their commute and are stuck indoors during the bright part of the day.

    While it may be a bit extreme, I think the ideal solution is to start the workday a couple hours past sunrise in the winter and a couple hours before sunrise in the summer. You'll be active during the warmest hours of winter and cooler hours in summer, you'll have free time during daylight hours year round, you'll commute to work in bright sunlight during the winter, and you'll avoid staring into the sun while commuting most of the year. Of course, nobody would want to a several-hour time change, so it would be better to spread it out: Lose a minute every night for half the year, then gain a minute each night for the other half. In addition, there could also be a couple jumps during the year to help avoid commuting at dawn/dusk. Getting people to accept waking up before dawn during summer and having sunset in the middle of the afternoon during winter might still take some work, but I think it would be safer, healthier, and more efficient for everyone.

    Oh, sure, we're laughing now... but this should be a wake-up call.

    While at first glance they seem almost indistinguishable from us, there is actually a vital difference between Ponies and ourselves—educational systems.

    Pony schools are far more intense than ours, especially in the maths and sciences. If you're familiar with the so-called "math" taught in our primary schools, you will agree that this image is disturbing. Young fillies (and colts, though their society is strongly gender-biased) are also taught a tremendous work ethic and social responsibility virtually from birth; in fact, they are expected to demonstrate exceptional talent and plan a career even before they reach adolescence. Furthermore, Ponies are even taught to take responsibility for the world around them. Their town, their environment...hell, the Sun, Moon and skies might as well be in their charge. They possess a drive that we fail to instill in our own children.

    None of this is particularly surprising when you consider that Equestria is an autocratic state whose leader has a singular fixation on education. While our leaders focus on populism and pork, Equestria sinks more and more resources into teaching even while its infrastructure and government services seem positively primitive.

    What does this mean for us? In the short term we'll continue to maintain our dominance in industry, but farther out...simply put, we're fucked. While our children fall farther and father behind, their foals dash ahead. They're already pumping out incredible individuals and technologies that defy belief. I fully expect that the first footprints on Mars...will be hoofprints. But that's not the worst of it. In the next decade, a pony will likely take your job. Soon they'll be running our entire country.

    I know what you're thinking right now: "Oh my god...Ponies, rule?". But the answer is yes, and I can't put too fine a point on it: It's only a matter of time before Ponies totally and completely rule everything. That is—unless you do something about it today. Write to your representatives. Tell them unless we all want to start singing Pony anthems, they can no longer claim to be strong on education while cutting budgets and shirking responsibility.

    Tell them that starting tomorrow, their actions must match their words.
