  3. I beg to differ.... We archive "forever" on Scientific Data Disappears At Alarming Rate, 80% Lost In Two Decades · · Score: 1

    Hello,

        Our mindset at my research institution is very different. We generate a certain amount of data per year (several terabytes), but the cost of storage decreases so fast we just copy old data onto new media and never delete ANYTHING.

          In fact, we consider the cost of actually figuring out what data to delete to be higher than simply buying more storage.

        I would not call it "well-indexed" however.

        Our backup strategy is tailored to the nature of our data. Most of our data is simulation results. We back up "lightweight" data and analyzed results, input files, and log files. "Heavyweight" data we do not back up, since we consider the cost of reproducing this data (given the input files and the log files) modified by the low probability of actually ever needing it to be lower than the cost of backing it up. This results in our backup requirement to be maybe 5% of our "live" data archive.

        If it gets to the point where we can't afford the storage anymore, we'll delete the "heavyweight" data ourselves to reduce the data footprint.

    This also applies to price-gouging: I will NOT buy a 20 year old song for $0.99. I'd pay $0.05 or $0.10. However, I will NOT "buy" songs from Russian sites at those prices because I don't consider the Russian sites to have legitimate rights to the songs in the first place. So I do without. Because I don't NEED your products.

    Fair price, no DRM, and my wallet will open for you like a floodgate--anything less and you get NOTHING.

    MY point is that even if obesity does NOT cause all the problems you mention, it is a problem in and of itself, and even if it is only 10% "cause" of the other problems, then diet pills will still help.

    YOU seem to be claiming that the only way to fix things is to fix the diet, and I would say that YOU are being too simplistic. Fixing the diet would be great, but in the absense of that, my point is that pills can be beneficial. Pills are, after all, easy.

    However, a weight-loss pill would at least address all those issues caused by simply being overweight alone, such as joint issues, high blood pressure, and some fraction of diabetes incidence.

    What's more, the less you weigh, the easier it is to exercise. Just imagine a 300 pounder trying to huff away on a hike or something. Losing the weight might be the springboard to a healthier lifestyle overall--something that perhaps would be unachievable with the extra 150lbs that are now gone.

    And as you point out, obesity is partly due to consumption of low quality food. Low quality food is cheap--it costs maybe $2k more a year for a family to eat healther, I see in the news today. $2k isn't exactly peanuts to someone on minimum wage, and it could be "$2k and a lot of time" for someone who lives in a food desert.

    Safe & effective "diet pills" might mitigate the damage and cost of a low-cost, low quality cheap diet--which is a win for everyone who pays into the medical system.

    I agree that pills like "Pen Fen" or whatever it was called, that cause heart issues, need to be treated with caution. However, the premise of the article was that pills that are safer and still effective have come out, but they're not being used.

    While it would be better for everyone to eat quality food and get appropriate amounts of exercise, a pill that mitigates the damage of NOT doing those things is just a big win for everyone.

    The perfect should not be the enemy of the good, and we shouldn't leave an 80% solution on the table just because it isn't a 99% solution.

    I can tell you I can more or less comfortably eat less than 1800 kcal/day at the cost of being sort of hungry, not VERY hungry. I assure you it's quite doable. I like the exercise though because it lets me eat more.

    All you have to do is not eat junky food, eat more of the less calorie dense foods like fruits and vegetables, and have other things to do in life other than eat--these make managing hunger on less than 2000 calories/day really, really doable. It also helps to track EVERYTHING you eat.

  20. Re:where are they? on Particle Physicists Facing Insane Competition For Work · · Score: 1

    Hello,

        I think you're pretty much stuck with copper for your device due to the thermal load you're going to put on it, though this is just a guess. Your 2 minute+ rest between pulses may spare you that necessity, but I don't have a good feel for the thermal issues unfortunately. The key calculation to do is figure out if the RF and electron bombardment heat load melts anything or creates so much thermal stress that something breaks during your pulse.

        Frankly, I don't think your financial resource is adequate for designing a new tube, not at all, because after you designed it you'd then have to build it, and I think that'd cost you $30k minimum just to build the tube, forget about the power supplies, cathodes, etc. I think your best bet is to salvage a tube from a decomissioning accelerator and use that.

        Since your application smacks of communications, are you sure you can make do with an oscillator? Or were you planning to pulse it on and off like Morse code?

        Also, I do NOT think you can count on fixing a tube when you melt it. These tubes operate under vacuum and tearing it down and putting in new parts is going to be both slow and expensive, and you don't seem like you have the cash.

        We haven't previously spoken of the Russians, which is a mistake on my part. The Russians like to say they've done everything in vacuum tubes before the rest of the world thinks of it, and they're not entirely lying. They might well have a used tube sitting around somewhere that might SORT OF meet your requirement.

        I think in the end though, no matter what you do, you're going to have to compromise on your requirements a bit to get something affordable on your budget, either that or 10x your budget.

        There was some RF stuff being done in Brazil a long time ago, i think it was academic work, maybe you could talk to them and get a cheap piece of used equipment.....

        As for me, I guess "physicist" is pretty close.
