  1. Re:Not buying it on After a User Dies, Apple Warns Against Counterfeit Chargers · · Score: 3, Informative

    I'm not buying it, how could you possibly screwup a USB charger to the point where it would be lethal? I mean the cables aren't generally thick enough to carry enough 220V current to kill someone before they melt and 5.5V DC certainly isn't going to kill someone.

    It only takes 100mA - 200mA of current to kill someone, and every USB cable is designed to carry at least 500mA since the USB spec says that USB hosts can supply up to 500mA of current (and many plug-in chargers exceed that). So it's certainly feasible that a USB cable can carry enough current to kill someone. It's not the voltage the determines the size of the conductor, it's the current.

    The USB cable wires may not have sufficient insulation to protect against 220VAC (peak voltage is higher, around 310V if I remember correctly), but that's the point -- 220VAC is not supposed to be supplied to a USB device. But even if it's not certified for the voltage it seems that the individual conductor insulation combined with the plastic outer sleeve of the USB cable would seem to provide at least enough isolation, I think most plastics used for insulation have around 500 - 1000V/mil (1/1000th of an inch) of breakdown voltage.

    I'm surprised that a phone doesn't have at least 220VAC of isolation between the USB power and the phone case. Is this typical in phones?

    You are part of the reason home delivery is so expensive. If you don't want to drive miles to a mailbox cluster, the USPS doesn't want to drive those miles to deliver a bulk mail envelope that only earned them 25 cents.

Paying 2x the current amount isn't going to stop anyone from sending you important mail, but it COULD stop bulk mail. I often have to dump 95% of my mail right at the door, and I bet I have already lost *some* important mail that was hidden between some junk mail I tossed.

    Since the USPS counts on bulk mail for the bulk (no pun intended) of its revenue, I think that if prices were raised to the point where bulk mail was stopped, the USPS would have to raise rates further to the point where its prices are the same as UPS and Fedex and it costs $12 to send a letter across the country. I don't think that's USPS's intention, and while many people wouldn't mind since they do so much business electronically, many others don't want to pay a $12/month service fee for paper billing or pay $12 anytime they need to get a document mailed to them.

Obviously, they drill and refine oil in your city specifically for you, and could not possibly be doing this in an area that is unattractive (except for the oil refineries).

Fortunately I only had one summer of helping with the hog slaughter, he sent them away to slaughter after that... that was my least favorite part of working there.

    But now when I drive to his farm I'm struck by the large numbers of isolated houses in what used to be farmland. And a lot of the family farms have been bought out by large corporate interests (who in turn sold the lucrative land to developers for housing) - there are a lot fewer farmers living on their own land as there used to be, many of the farmhands are living in the nearby town and commute to work. Most of my relatives have sold off their farms when it became harder and harder to make a living at it.

    My oil is refined around 20 miles from where I live, not some far away rural area. My oil arrives (largely) by boat, not sure where it's drilled but I certainly don't think I should be subsidizing oil companies to maintain their rural well sites.

    Nobody should subsidize anyone, IMO. Note that I said not a word about prices that USPS may charge for delivery to certain locations. I'm all for them charging more; that would give me a reason to review the deal with USPS.

    However many people live outside of cities just because they need the space. For an example, look here. Can you install such an antenna in your backyard (that you don't have anyway?) Other people have other interests, and often their needs exceed what a standard city home, with a one-car garage, can offer. Where do you set up your machine shop? Where is your nanoparticle-emitting 3D printer installed? Where do you do your welding and plasma cutting? You can't seriously suggest that human interests must be constrained to a morning jog in a park and a bar in the evening. I don't even know where any bar can be found in this area, since I have no use of them. But I have a good list of metal warehouses, electronic parts suppliers, and know every Harbor Freight within 100 miles.

    Even city dwellers manage to operate ham radios - VHF/UHF obviously has a lot of activity (and antennas are small and easy to disguise), but even HF is possible if you're creative, I've managed some good contacts with a 3 foot diameter magnetic loop, and I know people that set up a buddipole outside in a clear area with good results... take it to the beach for even better results. If you want to use a big antenna, then you can use a remote station either through a club, or rental. If I want to use a machine shop or 3D printer, rather than spending money building my own small shop, I can join a hackerspace and have access to far better equipment than I could afford on my own (along with instant access to others that are experienced at using the equipment and can help out when needed).

    This is so obviously untrue. Math to the rescue. USPS requires one customer per mile. Let's say there are two, and the road (dead end) is 10 miles long. There are 20 customers. A carrier has to travel 20 miles to make all deliveries if he starts at the mile 0 (and let's posit that the USPS office is there too.)

    I don't recall the USPS say they were wanted to increase efficiency for their customers, they said they want to cut costs. If the USPS can deliver mail to 20 customers with a single stop, then they save money.

    Now, if the carrier doesn't deliver then every resident has to drive to the USPS office. Let's even disregard the waiting time and focus only on miles driven. The fist customer drives one mile (0.5 mile * 2.) The second customer drives 2 miles (1 mile * 2). The third customer drives 3 miles. An obvious arithmetic progression here (every next resident has to drive extra to his neighbor and back.)

    Rumor says that the sum of an arithmetic progression is often found as n*(a1+an)/2. Since the a1 is 1 and an is 20, we suddenly learn that all residents have to drive 20*(1+20)/2 = 210 miles per day!!! Compare to 20 miles that the carrier has to drive. If we force residents to drive to their mailbox cluster (under those conditions, that are typical in rural areas) then it would generate a lot more pollution and wear of vehicles.

    You're assuming random placement of mailbox clusters - in general they'd be placed along main highways where customers would likely already be driving to run errands, so there may be 0 extra miles. There would have to be a much more intensive study to see what the environmental cost is.

    Of course there is one simple solution to that - let's outlaw rural homes and make everyone live in 100-storey skyscrapers; Gil the Arm visited one of such buildings, as I recall. Arcologies are very efficient this way. And who needs all that nature anyway?

    Or you could charge extra for rural delivery to make up for the higher costs. If you want to live in a rural area, that's fine, but why should others subsidize your lifestyle? Some people *have* to live in rural areas (farmers, for example), so they can charge the city folk more to make up for their unsubsidized cost of living.
