Comment Re:Is that even worthwhile? (Score 2) 113

There are probably 12 gas stations between my work and home. I can quickly check GasBuddy and see which one is the lowest and stop there without going out of my way. Sometimes my Costco is 10 cents/gal less that the others (usually just after all the other stations have done an increase), but usually the wait there is only a couple of minutes at the most. After prices have stabilized, Costco is usually within a penny or two of the others.

The other reason GB is handy is if you are traveling and don't know where the stations are. Typically, if you're on the Interstate the stations right at the exits are more expensive than the ones a couple of blocks farther. Of course other apps like Road Ninja are good for that as well.

Comment Re:I'll never give up incandescents. EVER. (Score 4, Insightful) 328

Don't you mean there are cheaper methods of heating than resistive heating? Because as far as I can tell, resistive heating is 100% efficient. Incandescents convert some fraction of the input energy to visible light. Almost all of the rest is emitted as heat. And if there was no light emitted, a resistive element is nearly 100% efficient.

No, he means more efficient:

In electrically powered heat pumps, the heat transferred can be three or four times larger than the electrical power consumed, giving the system a coefficient of performance (COP) of 3 or 4, as opposed to a COP of 1 for a conventional electrical resistance heater, in which all heat is produced from input electrical energy.

Translation: If your heating is all electric, with resistive heating you get a watt of heat per watt of electricity. With a heat pump you get more that one watt of heat per watt of electricity.

Had I done that, and had "allow automatic updates" turned off, my machine would have been been vulnerable for two weeks until I came back. I'm glad this one was automatically installed, while al of the other lower-priority updates have always awaited my approval.

I would imagine that the timing of this is one reason why it was pushed this way. As you point out, a lot of machines would be unattended until after New Year's and would be patched until then.
