    The data we have on the Earth presents a pretty good picture of warming, and the scientific consensus is that it's human caused. The trend in scientific consensus is also increasingly towards it being human caused.

    So not only all do all true scientists agree, but the percentage of scientists agreeing is increasing every day.

    Does that mean the true scientists are breeding or something? Should they all believe that overpopulation is a problem, just like global warming?

    Actually you can charge any lithium ion battery with a desk PSU, so long as it is regulated and has a current limit.

    Look at the graph here

    http://www.shdesigns.org/lionchg.html

    How it works:

    Panasonic recommends charging at a constant current of 0.7C until 4.2V/cell is reached. Then constant voltage (CV) is to be used until current drops to 0.1C. At that time, the charging should stop. The circuit follows this recommendation exactly. However it does not turn off the charge. Testing has shown that the current drops to almost zero anyway.

    The circuit simplifies this by limiting the charge voltage to 8.4v. When the battery reaches 8.4v, it will no longer draw current. The charger is also current-limited. Below about 75% charge, the limit current is reached. After about 80% charge, the current decays toward 0. At about 95% charge the current drops to only a few milliamps. In theory, the battery will never finish the charge, the closer it gets, the less current it draws. If left on the charger for 2 hours or so it will reach near 100% charge. But, 95% can be reached in less than an hour in most cases (assumes discharged to 50% or so.) Panasonic's charge curve for their 830mah batts using this method is shown below:

    If you have a voltage regulated PSU with a current limit, set the voltage to the voltage the battery has when charged. He has two cells in series, so he uses 8.4V. One cell would be 4.2V, n cells would be n*4.2V. Set the current to 0.7C where C is the cell capacity in mAh.

    If the cell is really discharged (i.e. less than 3.0V) you need to charge it at 0.1C until it reaches 3.0V before charging. This is not the normal case though, most LiIon batteries have a protection circuit that prevents this.

    http://en.wikipedia.org/wiki/Lithium_ion_battery#Protection_circuits_required

    Li-ion batteries are not as durable as nickel metal hydride or nickel-cadmium designs, and can be extremely dangerous if mistreated. They may explode if overheated or if charged to an excessively high voltage. Furthermore, they may be irreversibly damaged if discharged below a certain voltage. To reduce these risks, li-ion batteries generally contain a small circuit that shuts down the battery when discharged below a certain threshold (typically 3 V) or charged above a certain limit (typically 4.2 V).

    You can actually run most cell phones off 4.2V with no battery too.

    Actually a configured USB 2.0 device plugged into can draw 500mA at 5V (2.5W). And a configured USB 3.0 device in superspeed mode can draw 900mA (4.5W).

    Now cheap dumb (ie no microcontroller) USB gadgets have usually got away with drawing 500mA even when not configured and no doubt when USB 3.0 becomes common thet will get away with drawing 900mA. One USB 3.0 port could power a 2.5 inch hard disk which needs around 900mA to spin up, as opposed to two USB 2.0 ports. So no more Y cables.

    There's a Powered USB standard, except you need to pay a license fee to implement. It comes in three incompatible variants too, 6A at 5, 12 or 24V.

    I supposed the sovereignty is arguable depending on your definition. Per Merriam-Webster:

    "sovereign: one that exercises supreme authority within a limited sphere."

    I guess Saddam was the supreme authority in Iraq being a dictator and all, but at the same time he did not have supreme authority because of the UN resolution that forced him to accept UN weapons inspectors. He did allow them in for a while, but eventually stopped. That is why on:

    November 8, 2002: The U.N. Security Council adopts Resolution 1441 declaring Iraq has violated previous resolutions calling for disarmament and cooperation with weapons inspectors.

    Which is why they were invaded, and I could've sworn I saw many troops with the little UN blue flag in Iraq during the meaty part of the war.

    They could have just killed some UN guys and took the flag away from them.

    Ballistic missile defense is a much better bet against an unstable opponent with a small number of low tech nukes. No US president would be able to justify using nukes against those countries and killing millions of civilians, but I'd fully expect them to shoot down the incoming missiles.

    Of course you wonder in Iran's case how that will be possible, given that Obama seems to be willing to abandon the interceptors in Eastern Europe to appease Russia and now sign away space based interceptors in return for a guarantee that other countries that don't have the capability to do it will not do it too. And now it seems like he will not develop any new nukes for deterrence against Russia/China.

    Still I'm sure his apologists will now tell me that Russia/Iran/China/North Korea etc only want peace, it is only the evil US that wants war. Maybe, but what if you're wrong?

    Barnsley, however, armed with his Collage Theorem, thought he had it
    solved. He applied for and was granted a software patent and left acade-
    mia to found Iterated Systems Incorporated (US patent 4,941,193. Alan
    Sloan is the co-grantee of the patent and co-founder of Iterated Sys-
    tems.) Barnsley announced his success to the world in the January 1988
    issue of BYTE magazine. This article did not address the inverse problem
    but it did exhibit several images purportedly compressed in excess of
    10,000:1. Alas, it was a slight of hand. The images were given sugges-
    tive names such as "Black Forest" and "Monterey Coast" and "Bolivian
    Girl" but they were all manually constructed. Barnsley's patent has come
    to be derisively referred to as the "graduate student algorithm."

    Graduate Student Algorithm
          o Acquire a graduate student.
          o Give the student a picture.
          o And a room with a graphics workstation.
          o Lock the door.
          o Wait until the student has reverse engineered the picture.
          o Open the door.

    Attempts to automate this process have continued to this day, but the
    situation remains bleak. As Barnsley admitted in 1988: "Complex color
    images require about 100 hours each to encode and 30 minutes to decode
    on the Masscomp [dual processor workstation]." That's 100 hours with a
    _person_ guiding the process.
