  1. Re:Fireproof the garage on Tesla Says Garage Fire Not Charger's Fault; Firemen Less Sure · · Score: 1

    This doesn't make them fireproof, it makes them fire resistant, due to the high water content contained. This is the same concept as a "fireproof" safe, which is really only fire resistant. Once that water's gone, the temperature spikes rapidly by thermal conduction, even if the fire-resisting material itself doesn't burn directly.

    That's in open air, where each strand of conductor has proper cooling. Wiring for power transmission, you only want to shove around 5.9A through 14AWG. For 15A, you'd want at least 10AWG and more likely 9AWG to give you a safety factor. Yes, this is by rule of thumb, and doesn't take into account the length (increasing length increases resistance) , type of insulation, etc., but do you really want to take the cheapest possible approach when it can potentially burn your house down?

    The Maximum Amps for Power Transmission uses the 700 circular mils per amp rule, which is very very conservative. The Maximum Amps for Chassis Wiring is also a conservative rating, but is meant for wiring in air, and not in a bundle.

    I should say "potentially explosive" because it's not actually exploding until the confinement ruptures--explosively.

    The energy density of gasoline is higher. Additionally, though it's gasoline vapor that burns, any process producing a large volume of gas in a confined space can be considered explosive. The electric shock potential and dealing with lithium specifically seem to be more relevant concerns.

    "The fire occurred as a result of an electrical failure in the charging system for an electric vehicle," said a report by the fire authority, a copy of which was obtained by Reuters.

    The report also emphasizes that the cause of the fire is unclear.

    Whoops, butchered that comment. Meant to say an oily rag will spontaneously ignite if left for a few hours. You can try it yourself.

    Not a bad guess (still, I'll wait for the official report) in a garage, since most people don't seem to realize that an oily rag will if left for a few hours. You can try it yourself.

    Notice how little force they need and how easily their feet slip. This is a good thing. The problem with a treadmill is that you need to move this bulky rubber band around underneath you. It weighs a lot, as well. If you power a treadmill and use sensors to avoid using human power to move it, your power budget just went through the roof. Not to mention the need to spin the treadmill so the player doesn't walk off of it. Additionally, you're looking at moving parts subject to high wear and tear, versus this, which is mostly solid-state. I'd say this is a pretty inventive way of tackling the problem domain.

    How does a currency conversion (assuming you convert at current market rates) affect the actual price of the thing? Seems like you enjoy paying more for the same thing, since my currency converter here says:

    Conversion result: $291.40 (US dollars) - £178 (British pounds).

    It would take a decent skew in purchasing power parity to make up for that.

  14. What a ripoff on Free Software Foundation Endorses a "Truly Free" Laptop · · Score: 2

    I paid $200 for a Thinkpad T60 refurb (yes, a refurb, but you know, it hasn't faltered once). Comparable specs, faster CPU, less money. Not to mention this still isn't open hardware. I did have to strip whichever version of Windows came with it (didn't even look) and replace it with Debian, but it's been a quite a fine machine for work. (Programming, which doesn't exactly require a beast of a machine most of the time. Wowie! Look at that text editor go!)

    One time pads suffer from the problem of key sharing, which reduces their security to that of the key sharing/shared generation scheme.

    Partly because MS shoved every feature imaginable in there, and then some. I'm surprised there's not a feature-complete implementation of Emacs somewhere in there (but I wouldn't be surprised if there was).

    I was curious, after reading your comment, (this is Debian testing) so I rebooted, and went into BIOS. Well, no ACPI option. I did disable the microphone, as well as every power option I could find (along with anything else I could disable). I also booted with "acpi=off". I then fired up Audacity, and... it still records. Just like before. I think my time was not wasted reading your post, despite it still not disabling the microphone.
