Comment Doesn't matter, so why do it? (Score 0) 233

Why do we even bother with this? Why can't we just let noon move a second. Even after a hundred years it won't make any difference. Time zones on average vary in the suns position by a whole hour so a 1 sec variation of the solar zenith makes no difference. Anstronomers will still be able to find there stars.

So why even bother with this non sense?

Interesting, so in AZ you prefer IR and now low-e coating.

the purpose of the IR coating is twofold in the southwest. First, the object is not to keep heat in the house but to reflect the heat away. Most houses have a brow to keep direct light out. But it hits the ground and walls outside and then comes into the house as IR. So the Low E coating is actually intended to keep the IR out of the house. In the northern winters it's the opposite where you want to keep the heat in the house.

Second, the IR coating turn out to also be correlated with good UV prevention. Logically theres no need for those to be correlated. Practically they are. I can only speculate as to why: probably the processing to coat a window has enought set up cost that adding on a UV coating at the same time has low marginal cost.

So even in the southwest coated windows make sense

When my window replacement contractr cheated me by installing windows with IR coating I showed my kids how so visualize it from the reflection of a butane lighter flame. (the colors of the multiple reflections should red shift if it preferentially reflects red light).

I also showed them how the sun is about the size of a quarter and lands in arizona at night.

I have been wanting to see Apple or Microsoft or Netflix embrace torrent like local servers. But not for ads. For movies. Just push out all the movies to people's computers at night. Then let itunes or whoever form the torrent networks to deliver movies to paying customers. As long as I get a discount (since it's my bandwidth and electricity) why not? I'd like it as thumb in the nose of comcast and anyone else throttling the net.

I'm not talking about illegal file sharing, I'm talking about just having content served right within Comcasts own network so there's no peering issues.

Yes I appreciate how long comcast would let that go on. Just a fantasy.
