House Passes TV Commercial Volume Bill

wgaryhas Re:How is this legal? (408 comments)

They aren't regulating the volume of your television. They are regulating the volume disparity in the broadcast between the commercials and the shows. (It can be passed for the same reason FCC can regulate broadcast TV in the first place.)

Sahara Solar To Power Half the World By 2050

wgaryhas Re:Why DC when AC is better for long distances? (363 comments)

AC and DC power lines both loose energy to resistance. AC power looses energy in another fashion due to capacitance and inductance called reactive power. By using superconductors (0 ohm resistance) for the power lines, you eliminate all losses for DC, most losses for AC, and introduce new losses for the cooling equipment. Of course, with superconductors the formula isn't as simple as V=IR because then you could get infinite current. (V/0 = I) With superconductors, there is a maximum current density (Amps per m^2 as the area of the cross section of the wire) before the wire starts to produce resistance.

Gulf Gusher Worst Case Scenario

wgaryhas Re:I'll believe its an extinction level event (799 comments)

Its claiming a million gallons a day gushing, but at 4 barrels per second, you don't get to a million in one day. You don't even get to the 500k that BP would be so happy about, you get 345.6k/day.

barrels != gallons
1 oil barrel = 42 gallons

so 345.6k barrels/day = 14.5152k gallons/day

This doesn't refute anything else you've stated.

Congress To Hold Hearings On "Potty Parity Act"

wgaryhas What type of equal? (10 comments)

The bill proposes making sure there are an equal number of toilets in Women's restroom as there are toilets + urinals in Men's restroom. They are advocating spending more money and allocating more floorspace for Women's restrooms in comparison to Men's restrooms. They want to favor Women over Men, or they could just get rid of urinals.

Intel's Core i7-980X Six-Core Benchmarked

wgaryhas Re:Nice, but who has $1000 to pay on a CPU? (179 comments)

FUD, pure FUD. The Athlon FX-57 came out at an initial price of $1031 for distributors. While the intel competitor at the time, Pentium 4 Extreme Edition 3.73 came out at $999. Then the Athlon FX-62 came out at $1031 as well, then a month later the first core 2 duo came out for $999, and AMD hasn't been able to successfully charge a thousand dollars for a desktop processor since. So, saying AMD was never more expensive is flat out wrong.

More like the following:

You have service through ISP A

Website/peer has service through ISP B

for traffic to go from ISP A to ISP B it has to be routed through ISP C's network.

ISP C decides to throttle your connection.

Ocean Circulation Doesn't Work As Expected

wgaryhas Re:Darn it (658 comments)

Heat just one room at a time instead of the whole house. That's how you make a major change to help reduce greenhouse gas.

I tried that, had the heater turned off at all times except a space heater in the bedroom at bedtime. It ended up being more costly and less efficient than heating the whole house and keeping it heated.

My theory is that the insulation makes it pretty cheap to maintain the temperature, but the space heater has to work constantly to counteract the heat lost to neighboring rooms. The other possibility is that natural gas (whole house) is really cheap around here and electricity (single room) isn't.
