Tesla Model S: 0-60 In 4.5 Seconds

zach_d Re:320 miles (426 comments)

actually, the saw you have probably uses a plugging control circuit, that temporarily reverses the direction of motor, abruptly brining it to a halt.

Canadian Cannabis Car

zach_d Re:Why I'm not surprised (120 comments)

In a lot of BC it effectively isn't.

Walking around vancouver it's common to see people openly smoking joints, and I've even seen guys offer them to a police officer (somewhat cheekily, but still). The reason it's not legal in the whole country is that we fear the border would be frozen if we did legalize it. I'm quite curious to see what happens in the United States if prop. 19 passes. It could have quite an effect on our own laws, and political scene.

Kmart Briefly Offers $149 Android Tablet

zach_d Re:Uber geeky? (245 comments)

No, that guy does fantastic sushi.

Vancouver's got relatively high standards for sushi, and Tojo's is the best in town.

You pay for quality in this case.

Moving Decimal Bug Loses Money

zach_d Re:God Bless the USA! (420 comments)

Most vending machines will take an American quarter, and really, the exchange rate now doesn't make it worth getting excited, or even noticing when we get one.

What does suck is going to the States, and getting a handfull of one dollar bills in your change.

Smart Grid Could Pose Threat To Privacy

zach_d Re:That's why I leave everything on all the time (297 comments)

that's the nominal values, yes, but many, many hair dryers rely on the fact that breakers don't really break right at 15 amps. They rely on a thermal element to trip, and that element doesn't get hot enough, the breaker won't trip.

I've had breakers fail to break entirely, but certain brands notably Federal Pioneer will provide much more than the rated current, and for substantial amounts of time.

if breakers did trip instantly, almost every motor in household appliances would need a variable frequency starter, as the locked rotor current of most appliances is higher than 15 amps.

how many hostages have they killed?

honest question, I've never heard a report of somali pirates killing any hostages...

Mariners Develop High Tech Pirate Repellents

zach_d Re:pirate repellents (830 comments)

dude, how much do you think a CIWS costs? and the associate radar and fire control systems? what about the operator training?

even supposing those work, how do you propose to detect these raiders? they're in small craft that easily get lost in the sea-clutter on a radar screen.

  the fact of the matter is most ships find out they've been the target of a pirate attack when the guy with the AK walks onto the bridge.

12 Small Windmills Put To the Test In Holland

zach_d Re:A little sad. (510 comments)

see reply to parent,

but the same company makes a wirelessly connected retro-fit system.

also, it's not a terribly good idea to use a breaker as a switch, it degrades their over-current circuit breaking abilities.

12 Small Windmills Put To the Test In Holland

zach_d Re:A little sad. (510 comments)

lutron makes a collection of programmable lighting control systems that might be able to be adapted to what you're trying to do?

it would cost some money, as lutron stuff isn't cheap, but it could be made to work.

NASA Tests Heaviest Chute Drop Ever

gah, I'm sorry, clearly I should have read my post after I hit preview.

I meant that 32nds are closer than mils.

NASA Tests Heaviest Chute Drop Ever

zach_d Re:1 Question (226 comments)

I work construction in canada, and while we use Imperial most of the time, I actually find it a relief when we work a government job, and get to work metric. on a metric tape, you've only got mils, and they're way closer together than 32nds.

most of the time you're only working to the half a cent anyway, and you do way less low level math.

(and the code's written in metric here, so it's a bit easier to get things spot on code)

National Ignition Facility Fires 192-Beam Pulse

zach_d Re:indeed (438 comments)

Pardon me.

I've learned something.

I knew that H-bombs needed a fission reaction to initiate the fusion process, but I wasn't aware that fusion was also studied in controlled fission reactors.
