    Your stated formula was 1.5x , which is a linear formula - there are no exponents. Are you using a different formula now?

    No; exponential growth means that the growth rate increases as the sales base increases. "...growing at a factor of 1.5x annually" implies a steady, not exponential, growth rate.

    For the 9 months ending Sep 30 2016, they made $1,150,984,000 (1.1 billion) in revenue selling cars, of which $195,592,000 (0.1 billion) was from ZEV carbon credits.

    Tell that to the dead squirrel that I removed from my dog-rated wire
    It sounds like you might have found one where the manufacturer cut corners to save $$$.

    Why do you think that? I've used three different models; all seemed to put out about the same power and had similar warnings. BTW, they were rated for charging something lika a quarter mile of wire - I don't know about the battery powered models.

    Or it is possible that your dead squirrel had a mishap aside from encountering your electric fence.

    And it is possible thast the condemned man died from a heart attack just before the firing squad fired. But I'll stick to Occam's Razor: I'm going to assume that a dead squirrel lying across the wire probably died from the wire.

    I imagine your dog-rated . . .

    The charger wasn't specifically 'dog-rated', in fact it was mostly intended for livestock - but was suitable (and safe) for dogs over the indicated weight mark.

    . . . installation is closer to the ground than a normal electric fence, and it's possible that a squirrel tried to crawl underneath, then got trapped in there and snagged on the wire, unable to withdraw

    Very true. I used two wires - one at the top, and one about six inched above the ground to discourage digging. The squirrel - as well as one or two other critters, their species forgotten - were found bridging the gap between the wire and the fence. (I also found a dead owl on the top wire - felt bad about that).

    This is different from just coming in contact with an energized wire

    Yes, especially since the current is continuous. A battery powered pulse system might have taken out the owl, but I seriously doubt that it would have nailed the mammals.

    Why will it jam or explode? Jamming typically takes place after you fire, not before. Exploding means a seriously defective weapon (which could explode after a day) or a blocked barrel.

    But how does leaving it sit increase the odds of either? Fact is, guns are remarkably durable.

    You're absolutely correct, which is why my Colt Commander is always loaded. It can also sit on my shelf for years at a stretch without attention, and be counted on to fire within seconds of grabbing it.

    No, I'm not going to get into the habit of topping off the charge every now and then. I use my phone every day, I'm accustomed to charging it, but I have still been caught with a dead battery on occasion. An inconvenience, but usually not a fatal one.

    Assuming the fence is installed correctly with a proper fence charger; coming into contact with it is just going to sting --- not capable of causing al electric shock or serious injury even to a squirrel, let-alone a kid.

    Tell that to the dead squirrel that I removed from my dog-rated wire (the instructions warned against using it with pets under a certain weight - 15 or 20 pounds, as I vaguely recall.)

  13. Re: Legal? on Chemical-Releasing Bike Lock Causes Vomiting To Deter Thieves (bbc.com) · · Score: 1

    The electric fence you can have with proper signage is limited in amperage to about 100 mA, AND more importantly; it's not a continuous current like line power, but a small pulse of current lasting 1/300th of a second, and another pulse every second..

    Battery powered units do use the pulse system in order to conserve power. A/C powered units (or at least the three units that I have installed) provide a continuous current - but, as you mentioned, the power is safe for medium sized dogs, as well as humans.

    Chip and PIN was designed to shift some of the burden of fraud onto the consumer.

    Is this specific to the UK? I ask because in the US, chip and signature shifts the burden from the banks to the merchants - the consumer is unaffected. And where we do use PINs (ATM/debit cards). the burden is substantially on the provider.

    I did once have an ATM card compromised (probably skimmed). Someone withdrew $800 from my account in two 'normal' ATM transactions (card swiped, PIN entered). Within a few days of reporting it, I had a provisional credit for the full amount. ['Provisional' meant that the bank had six months to uncover evidence of fraud on my part.] My bank is to be credited for promptness here, but the basic provisions are a matter of law - the US consumer credit laws are very pro-consumer. I'm sure the same protections would/will translate to chip and PIN.

    'Retarded' may be a bit harsh - perhaps 'slow' might be more appropriate.

    You're assuming that performing innocuous read only file operations is sufficient cause to flag the macro as being a virus.

    Consider, for example, a legitimate macro which would present the user with a list of monthly sales reports. I haven't done spreadsheets since running Lotus 1-2-3 on a VAX mini computer, but your macro would essentially end up searching for 'SALES*.DOC' files - almost exactly what this one is doing.

    Would you bar any such operations? If so, you run the very real risk of having so many false positives that it essentially becomes useless to scan macros; simply block them by default on Office's side.

    This falls into the pre-loaded syringe category, with a one to two month shelf life. (The epi is drawn from a sealed vial into the syringe - no ongoing exposure to the air). And epi conveniently turns pink or red when it oxidizes, or produces a brown precipitate when it degrades. This can be seen through an inspection window in either the EpiPen or in the 'generic' auto-injector. And at one tenth the initial cost ($60/pair vs. $600), you're initially saving money in the short run. In the long run, the EpiPen is $600/18 months, about $33/month. The $30 generic injector has no shelf life - instead, both the syringe and needle are replaceable. Your monthly cost (needle, syringe, epi) should be around one tenth that of EpiPen.

    Big savings both short run and long.

  23. Re:Exploding or going up in flames on Samsung Galaxy Note 7 Explodes In New York, Burns Six-Year-Old Boy (arstechnica.com) · · Score: 1

    If I recall, technically an "explosion" is supersonic deflagration, which of course is accompanied by a shock wave. It's the shock wave that's the salient feature of an explosion.

    Practically anything flammable can explode if it is finely mixed with oxygen (or an oxidizer) and it is *contained*. If you pour the black powder from a bullet into a line and touch it off it's go up pfft! But it won't explode because it's not contained.

    I beg to differ. Modern smokeless powder will indeed go 'pfffft' (IIRC, a pile of powder from a 12 gauge shell took several seconds to burn). But smokeless powder is a propellant, not an explosive. Black powder, OTOH, is an explosive whether it is contained or not. Lighting a small pile makes a distinct popping sound from the wave front of the uncontained explosion.

    Eight in a ward does not sound like fun - in the US (in my experience, both as patient and visitor), two to a room is quite common, with nicer hospitals having private rooms. I had neck surgery about a month ago under MediCal (California's low income health plan) at a teaching hospital; I was quite surprised to get a private room for two days of recovery.

    I wonder if that is a trend now; perhaps in order to reduce cross infections.
