    That and 90 billion gallons of water in Alfalfa sent to China, and 97 billion gallons used for fracking...

    That's about 275,000 and 300,000 acre-feet respectively. According to the wiki, agricultural use was 29 million acre-feet, urban use about 8.7 million acre-feet. So the two uses you cite represent less than 1% of overall water usage each. (And are your figures nationwide or just for California? I assumed just for California.) I'm all for righteous indignation, but let's try to keep some perspective on scale.

    Also I hear the commercial water rate is lower then the residential rate, ie. the per gallon price is cheaper for the corporates then for the sheeple.

    As it so happens, I have our latest commercial water bill right next to me (for water used at a commercial strip mall in Southern California). $30 per hcf (hundred cubic feet) + $29.75 per hcf in service and delivery charges. Works out to:
    $59.75 / 748 gallons = 7.99 cents/gallon.

    My residential water bill is a flat monthly service charge of $26.87 + $2.29 per hcf for the first 12 hcf, $2.55 per hcf for the next 18 hcf, and $3.41 per hcf for any water use beyond that. Or:
    1 hcf = $29.16 = 3.90 cents/gallon
    10 hcf = $49.77 = 0.67 cents/gallon
    25 hcf = $87.5 = 0.47 cents/gallon
    50 hcf = $168.45 = 0.45 cents/gallon

    So once you get past very low usage amounts, the commercial rate is about an order of magnitude higher than the residential rate.

    I suspect it's agricultural water use which gets a lower rate than residential, and you're misremembering.

    It can be used both ways. What they're describing is basically tomography. By analyzing the signal recorded from different locations, you can construct a 2D or 3D representation of signal strength, thus allowing you to pin down a specific phone's transmissions based on location (rather than frequency or code or time - what's used for OFDMA, CDMA, and TDMA respectively). The reverse process would involve modulating the transmission strength and phase from multiple towers in a synchronized fashion so that the peak signal strength in a 2D or 3D field happens to be where that phone is located. It also frees you from the Shannon limit on bandwidth because the amount of channel noise is now location-dependent, rather than solely being frequency-, code- or time-dependent. Very clever work.

    Actually, the age of Aquarius is one of the few things astrologers got sort of right. The Earth's tilt precesses over time (just like a gyroscope), resulting in the solstices and equinoxes shifting relative to the position of the stars. Currently, the moment the Spring Equinox occurs, the constellation Pisces is directly overhead opposite the sun (i.e. looking at the center of the ecliptic at midnight). Over time, this will shift until Aquarius is overhead. An entire precession cycle takes just shy of 26,000 years, sending the Spring equinox through all twelve zodiac constellations during that span.

    What they got wrong was: (1) The constellations are not all the same size, so you can't divide a full precession into 12 equal ages based on the constellations. (2) The song in particular was based on a common misinterpretation of each age being 2000 years. Hence the misnomer that the the year 2000 was the dawning of the Age of Aquarius. Simple math should tell you that this doesn't work, as it results in only 24,000 years for a precession cycle. Dividing the precession into 12 equal ages actually results in each age being about 2150 years. (3) There are higher order effects also at play, so even a calculation based solely on precession is not exact.

    But it is in fact a real astronomical phenomenon behind the term "Age of Aquarius."

    This attitude that someone who is rich must be on an ego trip has always baffled me. It's hypocritical because your own ego is inflating your own self worth, making you think rich people are doing something which annoys you specifically to annoy you. The simple truth is, the rich are like everyone else - they don't care about you. It's just that being rich gives them more ways to not care.

    The solution then is to make them care. I've always thought cars should have return mirrors mounted on the front and back at the level of the side mirrors. e.g. On the front of the side mirrors, and on the rear about where the center brake light is. The mirrors (three mirrors at 90 degrees to each other forming the inside corner of a cube) will reflect any light back at the source. Putting them on every car will cause anyone with misaligned headlights to be blinded by their own headlights any time they approach another car from front or behind. It'll give them a clear indication (and incentive) that they need to take their car to the shop to have their headlights realigned.

    And the biggest culprit of headlight alignment misalignment I've seen aren't BMWs and Mercedes. It's off-road vehicles with raised suspensions whose headlights are not subsequently aimed lower. And cars with lowered suspensions whose headlight aim is then raised to compensate for the aiming point being lowered. A few states check headlight aim as part of their annual or bi-annual smog inspection before you can renew your car's registration. But most of the states I've lived in do not, so I think a more general and in-your-face solution is required.

    Currently, the merchants pay for credit card fraud. You contest a charge, the card issues a chargeback, and the merchant is out the product and money. The banks and credit card companies pay nothing for fraudulent use of the card except for the cost of customer service agents. The exorbitant interest rates you pay are to cover for customers who fail to pay their credit card bill.

    That's the entire reason credit card security is in the sorry state it's in. The party bearing the cost of fraud (the merchants) aren't in a position where they can improve the security of the system. The party who can improve the security of the system (the banks and card issuers) aren't paying for any of the fraud, so they had no incentive for them to improve the system - doing so would just be additional cost for no benefit to them.

    The garage door opener industry went through the same thing in the 1990s. People figured out you could record an opener's transmission, and replay it to open someone else's garage door. In that case, the party who could fix the problem (the garage door opener companies) ended up bearing the cost of the security flaw (they got sued). So they fixed it right away with rolling codes (the opener never uses the same code twice - it and the remote use a synchronized code which changes after each successful use).

    That it's taken the credit card industry 20 years to feel the same pressure to improve security tells you how good of a scam they had going. You should never be allowed to decouple costs from risks. If you profit from an activity, you should always be forced to bear the costs associated with it. Allowing you to transfer that cost onto another party (onto merchants for credit card purchases, onto the public at large for pollution) destroys any incentive to improve the product.

If they match, your contested charge is denied. If they don't match, the credit card processor executes a chargeback and the merchant loses the money.

    So yeah you can sign whatever you want on there. It's in the best interests of the merchant to insure that the signature you signed is your actual signature.

In a high crime/fraud area (e.g. corner liquor store) they may be anal about checking.

    And the 4-digit PIN is only half of the solution. The other half is a public/private encryption key stored in the card (hence why it's called chip and pin). This key cannot be duplicated without destroying the card. So to purchase something with a credit card, you have to (1) have the physical card with you, and (2) know the PIN. This is substantially better than the current situation where (1) you only need the credit card number, or a copy of the number, or a copy of a copy of a copy of the number, and (2) you can draw a picture of a cow for your signature.

    Common carriers are like phone companies. They provide the lines, but they cannot control who has access nor what is conveyed over those phone lines. If you call up to request a phone line be installed at your house, they are not allowed to say no (as long as you can pay). But in exchange, they are not liable for what is transmitted over those phone lines. If a drug deal happens over the phone line, the phone company cannot be hauled into court for facilitating illegal activity.

    Information services (the current FCC classification for ISPs) are the opposite. The ISP can control who they provide service to and what service they provide. But in exchange, they are liable for what's transmitted over their lines. If a customer is torrenting movies, the ISP can be hauled into court for facilitating illegal activity. This is why all of them roll over and hand over customer data when a proper DMCA claim is filed - they don't want to end up having to pay for their customers' copyright infringement.

    The last bit is the reason why the FCC classified ISPs as information services. The RIAA/MPAA didn't want to go through the trouble of tracking down by themselves individual users who were filesharing. They wanted the ISP to do the work for them - collect usage data, hand it over to them (via the feds), and shut the person down when ordered. So they pressured the FCC, and the FCC classified ISPs as an information service. But then the FCC tried to pass net neutrality rules as if the ISPs were common carriers. The courts rightly said "nuh uh, you can't have it both ways." Either they're an information service or they're a common carrier. You cannot say they control and are liable for the data they carry in one case, but they're not allowed to control what data they carry in another case.
