Comment Re:Lefties? (Score 1) 11

If "not being a sociopath" is left, than I guess you're right, I'm a leftist. It comes from too much Sunday school, I suppose.

Comment Lefties? (Score 1) 11

If not being heartless is being a leftist, then I'm leftist. Letting children die so you can become even more filthy rich is just pure evil.

This is a drug that costs less than ten bucks to manufacture that stops children from dying a horrible death from a severe allergy. Charging six hundred bucks for it is beyond criminal and wel into Evil with a capital E. Satanically evil.

Comment Taxes are punishment? (Score 1) 4

If taxes are punishment then the rich need their taxes tripled after all the unpunished evil they've done so far this century. The poor are being punished enough - by the rich. If having to pay for roads and bridges is punishment, then having to pay for food and water is, too.

As a Christian, I have no problem with taxes (Mark 12:17). Of course, if you worship mammon rather than God, taxes would indeed be punishment.

Comment How efficient is hydrogen really? (Score 3, Interesting) 198

OK. How efficient is hydrogen, really? Shout out to all of the chemistry majors out there who might answer this.

One of the reasons that fuels work, from my understanding, is that you start with a small number of molecule, combust them, and get a larger number of molecules with more heat. The heat increases the pressure, and the increase in the number of molecules increases the pressure.

Example: combustion of alcohol:

C2H6O +3O2 --> 3H2O + 2CO2

We start with four molecules on the left, and get five molecules on the right. Even if the reaction was not exothermic, we would still get a pressure increase good for pushing a piston.

Now, when we burn hydrogen, we get a decrease in the number of molecules (goes from three down to two):

2H2 + O2 --> 2H2O

So, yes, we get increased pressure due to heat production, but we get decreased pressure due to fewer molecules.

So, I guess that my question is: when burning a fuel, how much pressure created is due to the typical increase in molecules, and how much pressure is due to heat?

no, that's pretty much what the bible says to do...

Yes, I should listen to somebody who has probably spent many, many minutes learning about the bible....

John chapter 8. Some guys bring a woman to Jesus to see if he is willing to stone her. His response? "Let any of you who is without sin be the first to throw a stone at her." Needless to say, the woman lived.

That is called the "New Testament" and covers the life of Jesus and shortly afterwords.

I say, make guns like driving, but on a "shall issue" permit requiring a reasonable proficiency test.

So, my drivers license is good in all 50 states. If I get a concealed permit, that should be good in all 50 states too, right? If you want it more like driving, then you should not get to pick and choose which parts of that analogy you like.

Thou shalt not kill

Those two are kind of the same thing...

Plus, the real quote is usually translated as "You shall not murder"(hebrew "rasah") which is different from kill. If somebody is trying to kill you, the bible does not say that you cannot defend yourself, which goes well with gun rights.

Comment Re:MS Hates Linux (Score 1) 470

How many of those 33% would go and buy the PC through the Microsoft Store? Why wouldn't they just buy it from Lenovo if they don't want to run Windows?

The summary explicitly stated "Best Buy." If you are going to purchase a laptop and don't want to wait for shipping, going to a place like Best Buy is certainly not unreasonable (especially since they price match placed like Amazon). Having purchased what was believed to be an "ordinary" PC and not being able to install the OS of choice is, understandably, a bit of a shock.

To people who have strong feelings about Best Buy: don't read this as an invitation to bash/praise them. This comment is simply that the machine apparently was not purchased from Microsoft, no handcuffs were not expected to be included with the purchase.

Comment Re:So in other words it's used and is useful (Score 1) 248

But they said it's a "barometric vent"; not a barometer. Could it just be a hole to make sure the internal and external pressure are the same?

I remember when the waterproof Yaesu VX-7 radio came out (hand-held amateur radio transceiver), and it had a problem with being too sealed.. The problem with anything that is waterproof and has a speaker and/or a microphone is that the pressure on the inside can be very different from the pressure on the outside. If you change altitude, you will find that the pressure difference inside can press on the speaker diaphragm and/or microphone diaphragm. This limits the diaphragm travel, and will result in distorted audio. When this happened on the VX-7, the users discovered that they could crack open the battery case to "burp" the unit, restoring normal audio (at least until they changed elevation again). The eventual solution from the manufacturer turned out to be (from what I understand) to actually put a hole in the case and cover it with Gore-Tex. Water still stays out, but enough air can get through to equalize the pressure.

Since the iPhone has both speakers and microphones, something like this is needed if you really want to make it waterproof. Since the interior then has the same pressure as the outside, that makes it easy to drop a barometric sensor anywhere there is space on the board.
