  3. Re:a better link on Toshiba Battery Charges In 10 Minutes · · Score: 1

    Different types of batteries tend to have different behaviors.

    Li-ion batteries are good at around 40% for storage and should be kept cool.

    NiCads are the ones that should be discharged all the way occasionally. NiMH are similar although they are not as sensitive to not being fully discharged. Interestingly, these sorts of batteries have a similarly shaped discharge curve but it is a few percent weaker. This combined with shutoff circuits that react at a certain voltage is why the battery life on old camcorders and laptops seemed to drop off so quickly.

    Lead Acid batteries are probably the most tolerant of overcharging. If you let them drain to zero, they will have a short life. There are starting batteries like in cars that are good for short, high amperage bursts. There are also deep cycle batteries that are not as good at delivering hundreds of amps but they are much happier with being run down.

    That diet is actually the eating pattern that doctors recommend to most patients in general if they can possibly do it. By eating many small meals, you will generally eat the same amount of calories (give or take) but your metabolism will be much higher. If you eat 20% more calories with that kind of diet, you will probably still lose weight.

    It is just hard to get in to the habit without over eating.

    I understand that you really don't like certain politicians and certain stances and ideas. I have to wonder though, can you really say that a major political party be considered a conspiracy? This is a political party that holds open elections, has existed since the 1800's and has 55 million members (roughly 1/6 the population of the US) in all 50 states. It doesn't seem to really make great argument for conspiracy.

    I95 splits in to I495 (aka The Beltway) south of Washington DC in Virginia and north of Washington DC in Maryland. To be pedantic, it's I495 that's terrible.

    Then again, so is I66. And US Route 50. And I395.

    And... Yeah, they all sucks.

    Honestly, I think that one of the major problems in the Washington DC to Virginia area is that there is a river that limits traffic to bridges. Sacramento suffers from Similar problems at all the big roads across the American River (I5, California Highway 99, I80). It puts a natural choke point near in certain areas of major roads. People only going a few miles have to go the long way around and end up on the major roads. Because these are congested, the slowdowns spread to other major roads in the area.

    Lately, transportation engineers have started to suggest that local roads should be build like a web instead of the "hub and spoke" system that was used in the 50's and 60's when the interstate system was built. A good "arterial" system can relieve a lot of congestion on major roads because people making local trips can avoid the major roads.

    One other problem in the Washington DC area is that a lot of the growth has gone to the West into Virginia North of where the old developments were. These are areas that extend to Dulles Airport and then beyond. There is no metro line that extends out there to relieve traffic. There is also no Virginia metro line in that area. AFAIK, there are plans on the table to build a line to Dulles but it is in constant redesign and litigation, Federal funding is questionable and the time line is fairly long so it won't help congestion any time soon.

    Speaking of Federal and other funding, a lot of this growth is along Virginia Route 7 which toward the west is known as Harry Flood Byrd highway. They should really follow the model of that road's namesake, Harry Byrd in funding either a new road or a metro line.

    Since a lot of traffic problems are local, the local government should fund and solve them. Major routes, beltways and rail lines that extend between states would need federal funding however.

    I think that I think about this stuff too much while sitting in traffic.

    To be clear - it does "bad things" to SOME Radio waves. Water absorbs radiation at 2.4GHz remarkably well. That's why it is used in microwave ovens. At 900Mhz, you won't see nearly that much absorption. The same holds true going higher but the signal be much more likely to deflect the higher you go.

    In the end, it doesn't matter because you're only licensed to use so much and thus only so much gear is available.

    That is true for new cars. If you purchase a used car and plan on driving it until it's dead for good, there is a pretty big difference. At one point the resale value of the car starts to approach a value because a working car always has some value. At this point, the value of the car is probably below the value the car provides in your life.

  17. Re:True... for everyone but you of course on Multitasking Makes You Stupid and Slow · · Score: 2, Interesting

    IMO The biggest challenge/danger regarding e-mailing when driving is limited visual capacity. Your macula (the part of the retina that does detailed vision) can only be pointed towards one place at once. As a result, when you are looking at your computer, you are not looking at the road. The other problem is that most of us either hunt and peck or type with two hands. If you type with two hands, you are going to need to look at the keyboard to type so you can keep the other hand on the road. If you hunt and peck, you still need to look to see what key you are about to hit.

    Most of us have the ability to explain a complex concept while driving. If the visual constraints were out of the way, I would imagine that this would easily translate to writing. The worst it would probably do to you is make you more likely to miss an exit on a highway* or make your writing a bit less concise. I might not write a formal e-mail to my boss, but I probably wouldn't mind e-mailing a friend or something like that.

    I have missed an exit before on a relatively short trip (~20min) down a highway when thinking about my day or listening to something interesting even though I am still fully focused on and can react quickly to the road ahead. I am not the only one to have ever done so. I think that the previous poster who said that much of driving should be automatic was right on - your "muscle memory" takes care of a lot of the basic tasks that control the vehicle and even watching for visual problems. Higher thought comes in when planning a route or when changing lanes.

    While people do go to crazy about the effects of "radiation" from electronics, there can be problems. In the VHF range for instance, about 200W of energy can give you a severe burn. Different frequency ranges have different absorption levels in the body. The electromagnetic radiation is somewhat cumulative so a lot of RF at high power is not a good idea; They say that RF burns are like sun burn under the skin.
