    Residential weight scales, when they're digital, are generally accurate to 1, .5, or .2 pounds. Figuring that people who worry about that are 200 pounds(for ease), that's around .5, .25, .1% margin of error.

    A standard 20' container can weigh as much as 53k pounds. 5 pounds for that would be .009% error. Or around 10 times more accurate than the best commonly available bathroom scales.

    I'd call that 'precise'. Of course, given industry I wouldn't be surprised to find out that they're accurate to within the pound.

    Crazy people (i.e. the sort of people who commit random murders) aren't all that likely to machine their own gun. But if you make it as easy as a few key strokes on a PC, they're a lot more likely to do that.

    I'd argue that they're also unlikely to have a 3D printer in the first place. I think there's still likely more people with access to machine shops than 3D printers at this point, and if you want the parts made out of plastic a machine shop can still do that - create a mold, and if necessary machine it down a bit. You might use a different bit to carve up plastic than you do wood or metal, but it's known.

    Plus, well, it's probably still far cheaper to have a shop make your bits than to buy a 3D printer solely for that task.

    Manufacturing guns used to mean specialist equipment, specialist suppliers.

    Manufacturing a good firearm means this. But in reality, any decently equipped machine shop can churn out firearms if it so chooses.

    For example, the FP-45 Liberator, produced during WWII. Unit cost was $2.10 per firearm, 1M were built by 300 workers over 11 weeks. By my figuring, that works out to 8 minutes per firearm, using WWII manufacturing techniques. If you want deluxe, the M3 Machine gun ran $20 back in WWII. Too expensive? Go with a Sten.

    Consider if I'm a legal gun maker, of course I'm going to obey the law. So how much does the government need to track me? Besides, all my equipment(see above) is for working with metal.

    It gets very complicated if you're trying to prevent people from making non-metallic firearms - because you have to look away from the developed firearm industry. You have to worry about injection molds(all over the place, fairly easy to make, actually), not sheet metal presses. People who buy ABS plastic, not order a highly metallic rifled barrel online. Etc...

  13. Zip guns on In a Security Test, 3-D Printed Gun Smuggled Into Israeli Parliament · · Score: 2

    then making something plastic is the way to go as sometimes... a single lucky shot is all you need.

    Igw's point still stands. While I'm sure it'll happen at some point, nobody to date has been killed, or even faced a serious assassination attempt, by an assassin attempting to use a plastic gun. Not even the CIA's rather incompetent and rather silly attempts to assassinate Castro, at one point attempting to poison his cigars, has attempted the use of a plastic or otherwise non-metallic firearm.

    The Liberator is printed using the same ABS plastic that Legos have been made from for decades. Just like legos, there have been developed processes for making parts out of ABS plastic that, while it isn't 3D printing, is fully up to making all the parts used in a Liberator.

    While if you're making 1-10(estimate) of these firearms it's probably cheaper manpower wise to print them, there's nothing about the designs that prevents the use of conventional molds to pop off a few thousand liberators at a drastically reduced cost. These processes were available in the '40s. They've had well over 60 years to create a plastic gun, perhaps at greater expense, but in the realm of assassination the use of rifles and bombs that run in the tens to hundreds of thousands of dollars is accepted. Worst case, you might have to do some subtractive piece work - use a drill or router to 'clean up' a piece.

    Conclusion: The Liberator is the best 99% plastic gun yet(firing pin is still metallic), but it's still a single use zip gun of such anemic performance that you're probably going to be better off making a zip gun that has metal parts that look innocent that you can fashion into a firearm once past security. Or using a bomb, poison, rocket, longer ranged rifle, knife, garrote, bare hands, etc...

  14. Is the science final? on Farm Workers Carry Drug-Resistant Staph Despite Partial FDA Antibiotics Ban · · Score: 1

    I remember reading an article where they've never really traced a drug-resistant strain as having come from preventative antibiotic use, that the biggest source of resistant strains is people failing to take the full course of their antibiotics.

    The theory espoused was that preventative doses of antibiotics, being below that of clinical treatment, are enough to 'disadvantage' targeted bacteria such that immune systems did most of the heavy lifting, preventing infections from taking hold. But at the same time the lower doses don't trigger the major evolution steps to become immune to the antibiotic, as the evolutionary pressure isn't there.

    It was also mentioned in the study that antibiotic use tended to be stable whether they used antibiotics as a preventative or not - Therapeutic doses are far higher, thus the additional occasional need to actually treat the cattle with full up antibiotic courses to treat actual illness evens out(within error of margin) total average use. It's just in sharp spikes rather than being even.

    All this being said, if you're going to be dosing cattle with antibiotics to help them grow faster, you should probably stick to the older drugs, not 'front line' antibiotics intended for patients with resistant strains.

    If we could make some sort of machine, or more likely a set of machines, that could manufacture more of themselves as well as machines that make and install the solar panels, while taking sufficiently less energy to maintain themselves(and being efficient about the panel process itself), we'd only need to set up a number of them with the appropriate programming and wait.

    1. All of it, until something breaks, at least.
    2. The life of an electric motor of the sort put into EVs should outlast the EV itself.

    We have electric motors that have been in continuous operation for over a century. Given the limited mechanical wear, you should only need to maybe replace the bearings. Other than that you're looking at the breakdown period for the insulation.

    Quick lesson on electric motors: The 'strength' of an electric motor is limited by around three major factors:
    1. The voltage the insulation can withstand before it breaks down.
    2. The amount of heat the insulation can withstand without breaking down
    3. The amount of heat the motor can dissipate.

    If the motor becomes less efficient, that means it's resistance has risen. That means it's dumping more heat into the motor itself, raising it's own temperature. While there's overhead, they don't put huge amounts of overhead in. That means that a electric motor that's operating less efficiently, for whatever reason, is going to either burn itself out or trip temperature safeties. Probably the latter for a motor in an EV. A computer fan burning itself out isn't a big deal; the motor in an EV is big and expensive enough to justify additional safeties/diagnostics.

    Really, the most likely bit of maintenance would be replacing the bearing every so often, but outside of trouble we already have the capability of making bearings that are expected to last well over 500k hours. That's 57 years per bearing set...

    You should be hitting 65-70%, not 60%, and that's before considering the benefits of regenerative braking.

    have zero financial management ability whatsoever.

    I think this is the critical part for that little bit, plus they might not stick around for the requisite 5 months either.

    I'm reminded of a saying: It's expensive to be poor.

    I'm going to expand on that a bit. "Rich" and "Poor" are more statements of assets than income. My mother is a personal accountant. She's known of people with more or less identical incomes and family situations, but one's a multimillionaire who lives in a modest house, and one's broke every month that lives in a slightly less modest house. And no, the difference in houses doesn't come anywhere NEAR explaining the difference in assets. In addition, every so often you hear about some janitor dying of old age and his will donates his estate to the University or whatever, and it's several million dollars.

    I thus present my theory: Being 'rich' or 'poor' is less about income than it is about spending. Poor people tend to get horrible effectiveness with their money - they end up paying lots of non-productive fees just for using money(NSF, check cashing), high interest rates(credit cards if they're lucky, payday loans, 'buy here pay here', etc... if they're not), and any cash they do manage to save ends up in a mattress losing value due to inflation as opposed to invested making a return.

    Middle class and rich are far more effective. Please note that buying a $100k pizza that comes in a diamond encrusted box isn't a move of the 'rich', it's a move of a poor person who managed to become rich temporarily due to income managing to exceed their expenses, and is a sign that they're on their way back down.

    One example from Pratchett's Diskworld was boots - the poor man would buy cheap ones with cardboard soles, the rich man would buy good leather ones. The good ones cost 10X as much as the cheap - but the cheap boots only lasted a few months, the good ones would last decades. But because the poor man could never scrape up that 10X, he was actually stuck paying more for footwear... I remember reading a real world example where a poor person would buy the smallest ketchup bottle(for example), even though the economy size with double the amount was only like $.25 more because it was the cheapest unit, not because it was the cheapest per unit of Ketchup... Many poor people have economic blinders on.

    That being said, I think regulation is needed to keep employees from being raped too badly by these debit cards. I also have the fear that where a poor person might be able to understand cash, they might not understand their card's balance, especially when it costs money to so much as check.

    I was mostly concentrating on Bush's reasons to go to war. It does seem that Saddam was playing a coy game about possibly still having/working on them, they did have a rather nasty shooting war with Iran, and having the weapons was supposed to be a way to defend against their rapidly improving military.

    Roughly speaking, I hate it when people post things like 'it's all about the oil!!!!'. Let's face it: A government isn't a person. It doesn't have views, much less feelings. The best you can do is look at a general trend of the individuals within the government. Everything else is complicated interactions.

    For example - Oil might explain the first gulf war, but Iraq doesn't have the oil reserves Kuwait did. Even if it did, you'd logically get a Saudi Arabia situation - hate their guts all you like, but the black gold will flow. If it was truly about the oil, it would have been far cheaper to ignore Saddam's abuses and simply paid his price. Even if he refused to sell to the USA, he probably would have sold to Europe & China, and those areas would simply have bought less US, Canada, Mexico, Central and South American oil, leaving it equally cheaper on the international market.

    In reality, I figure 'possible WMDs' was actually pretty far down Bush's list of reasons for invading Iraq. But it was the one that sold for getting what international cooperation he was able to get, thus is the one he ended up pushing everywhere. I mean, we talk about politicians being dishonest left and right but believe Bush when he says it was about the WMD? Or attribute it to 'Oil!' when we went about it in a way that that would be so inefficient about it? One wants to get into nitpick theories, it was also a 'safe' way to validate US military combat theories. We paid a heavy price to gain our current skills in the area; and they're subject to degradation if you don't have combat to keep them up.
