Awesome! Mine's 6:33 but the last time I did it, it was over 7:00. I have to learn to string the thrusters together better.
Sound like a cool gym. Have you also notices the high nerd quotient in crossfit? Our gym is full of nerds. Kinda neat.
The difference is that the article IIRC had people working at 55% of their max or something. That's really nothing. I'm talking about doing 5-10 minutes at your max. E.g., look at the CrossFit workout named "Fight Gone Bad" (http://www.fgb4.org/2009/05/24/the-rules/). That takes only 17 minutes, and every time I've done it, I've gone so hard that I've puked at the end. So that's 17 minutes at 100%. There's definitely afterburn there. I'd even volunteer to go into a metabolic chamber to show it.
Paleo-Zone is even better. Cut out all those grains and eat like a caveman!
Plus, I do think that the "afterburn" is true (even though the article said otherwise). I eat 3000-4000 calories a day (depending on the intensity of the workout) and I'm still losing weight. As my workouts are only 10-15 minutes a day, I can't be burning all of that during the workout.
What everyone needs to do is go to the CrossFit main site: http://www.crossfit.com/ and look through their research on exercise AND diet. I totally recommend the lifestyle they preach. I've been doing the workouts for about 4 years, but didn't change my diet until last spring. Doing both CrossFit + Strict Paleo, I'm down 25 lbs in 6 months: 6', 175 lbs. Some Benchmarks:
100 Pullups - 5 minutes
1 Mile run - 6:15
I can lift 200 lbs over my head
I could go on but people already view CrossFit cultish, so I'll quit before you think I'm TOO crazy.
Yes and no. It's still really sloppy and not well commented since it's still a pet project. Plus I know that it's not popular around here, but because of questions like the OP's, I think there's some value in actually productizing this code, so I don't want to throw it out there to the public just yet.
UPB (Universal Powerline Bus) is the same idea at X10 and unfortunately much more expensive because of licensing issues, but the reliability of the communications is really good. It comes with a (poorly written) windows program that allows you to setup commands and stuff, but because of the ease of the UPB protocol I've just written my own C++ code to monitor the Bus and send commands to do things. I send an email to my house when I leave work, then the software reads the UPB temperature sensors inside and outside to determine when and if the heat should be turned on. When the light sensor notices that it's dark outside, the porch lights go on. When my car comes in the driveway (induction sensors) and I'm not hope the first floor lights go on. I unlock the front door with a key fob. And lots more. Blinds open and close depending on sun levels, inside, and outside temperature. Lots of really cool logic! I'm working right now on artificial intelligence to guess when I'm coming home, when I'm going to bed, all of that stuff, it's just hard because my schedule isn't very regular. Anyway, to get back on topic. I had to write all of this myself because the offerings out there are no good, if you want anything beyond the basics you won't get it. If you're a good hacker, it's worth it just to write a service that can read and write UPB commands and you can do anything you want (there's also a UPB-X10 bridge if you want to use X10 hardware).
Where did you get a 56lb kettlebell? I've only seen 24Kg=53lb or the ones that are rounded up to 55lb.
Anyway, Crossfit is the only way to go. It's a great workout, and it's especially great if you can go to a Crossfit gym. Having people around you pushing you makes you go even harder and get into even better shape. I did Crossfit on my own for a while, and saw lots of improvements in my fitness compared to the normal gym rat stuff I did. Then I joined a Crossfit gym and I saw another round of gains. I can honestly say I'm in the best shape of my life right now, and I only workout for 10-20 minutes a day.
Then you just do phased-lock detection. In the IR with current cheap detectors you can modulate in the kHz without any problem. I wouldn't be surprised if they do that now. In my lab we look for changes in an IR signal that are about 10^8 times smaller than the background IR radiation. It's not a hard problem to solve.
Granted, there will be a little more inefficiency in the larger alternator needed. But also remember, that if you're not drawing any current from an alternator, the torque required to turn it is very small, and only dependent of the friction in the bearing of the alternator. So basically, the times you don't need the power from the alternator, it's easier for the engine to turn it.
The torque required to turn an alternator is the sum of some constant value related to the mechanical friction plus a variable term that proportional to the current (really power) draw on the alternator.
Also remember you have a battery in a car that can buffer quick changes in power need. That is, you have a low power alternator constantly filling the battery and when the power steering needs lots of current it takes it from the battery. With proper sizing of the alternator and battery, you could get this to work really well.
You seem to be a CrossFitter....what's your Fran time?
I'm still trying to learn POSE, I just can't coordinate it. I spent WAY too many year learning to run the wrong way and retraining all of that is going very slowly.
The hydraulic pump is running all the time, even if you're not turning. It's much more efficient to have the electric power steering (which is much easier to make variable assistance too) only kick in when you need to turn.
I don't think even the dumbest electrical engineer out there would design a dimmer with the resistor in parallel unless their goal was burning down houses.
Nope, that's not right. Since we're talking about a resistive load, I can make the simplification that Power=Volts times Amps (and Power is proportional to Dollars).
We know that V = I*R. Since V is constant (120v RMS), we can only change the current in a circuit.
Undimmed the Light provides a resistance RL on the circuit.
Dimmed the Light plus dimmer (assuming a resistive dimmer, some are choppers, but I'm ignoring that now) provides a resistance RL+RD on the circuit.
So Undimmed the current, IL, is V/RL
Dimmed the current, ID, is V/(RL+RD)
That means that ID is less than IL and if the Power is V*I, then PD=V*ID is less than PL=V*IL. So less power is being consumed.
The point of this is to be able to use less chemo with the nano tubes, not using the nano tubes as a treatment for the side effects. If you can get away with less chemo, then the side effects will be less, and that's always a good thing. I took more drugs to deal with the side effects of the chemo than the chemo itself (and no, the pot didn't help me). Anything that can make treatment more bearable is great.
Light itself doesn't make a zig-zaggy motion, but the electric and magnetic waves oscillate in a zig-zaggy way. Light is nothing more than an oscillating electric (and magnetic) wave. Probably have to go to wikipeida for a good picture
Going back to the wave on a string example. If two people hold the string and one shakes it. The string itself will oscillate but the energy associated with that motion travels straight to the other person. It's hard to explain or imagine if you haven't spent a lot of time in physics classes, but a wave is just a way to transfer energy. The wave may make the string move up and down but the energy is going "straight". This is a terrible explanation, maybe someone else can do better.
The trouble is when you actually start to get into the details of wave motion and how light behaves, basically you just need to trust the equations and there are few physical examples of how it actually works (other than a wave on a string). And then the people who study this all the time just think in terms of the equations and don't really know how to explain it.
Anyway, to answer the the OPs question here's a simplified example (real physicists, don't hate on me, I'm not going to get into the gory details here).
First, lets think of a wave in the water. It's traveling in one direction (towards the shore) and vibrating in another (up and down from the plane of the water). Light is the same. It travels in one direction (from the theatre screen to your eye), but it can vibrate in two directions: up and down, or left and right (and technically any combination of that like diagonal and such). This is called the polarization: vertical or horizontal.
So what these 3D theaters do is have a special theater screen that preserves polarization (most just randomize it) and they have one image for one eye sent out in vertical polarization and the other sent out in horizontal polarization. Then by using special glasses they can show only one polarization to each eye.
Think of polarized glasses as having little bars in them, if they're aligned up and down only vertical light can squeeze through the bars, the horizontal gets stuck. Likewise the bars can go horizontally and the vertical light gets stuck.
Actually it's the other way, but that's more complicated. If the bars (i.e. molecules aligned such that they conduct electricity) are vertical, the vertical polarized light resonates with the bars and gets dissipated and the horizontal makes it through. But that's just technical matters.
This is also why polarized sun glasses are great for boating and driving. Since most of the time you're looking out at a big horizontal reflector (the water or your car hood or the road), most of the light that's reflected (glare) is horizontally polarized (I won't go into the details why), so the polarized sunglasses are set up to filter out horizontally polarized light which removes glare and you only get the vertical light which is just about everything else.
I see your point, but think conversely: I make a quantum computer that's cheap enough to fill a data center but there's no algorithms out there? What use is it? We need the physicists our there making the quantum computers and we need the computer scientists out there developing the algorithms. One without the other is useless. Also think of this: Dijkstra's "Go To Statement Considered Harmful" was published in the late 60's, there weren't many cheap computers to fill data centers then. He was working on the theory of algorithms not worrying about how to actually implement it. The same thing here, there are people working on the theory of these algorithms, other people will worry about actually using it when the time come.
This is fairly old news. We've been seeing the same stuff in our lab for about 8 years (also came across it during Quantum Dot research). It's been very hard to characterize. Cool stuff. Since you have x, y, and z resolution when you're "writing" to the photosensitive material, and these spots can be diffraction limited in size, you can imagine the storage density of read-only optical media for this.
I agree with you that letting people see the source is the only way to verify that things are done right. I'm just questioning if there's the GPL has any legal way to make them show the source code, or really what constitutes "distributing".

Paleo? Or generic low-carb? I've been doing Paleo for six months and have never felt better nor has my athletic performance ever been better.
Yup, if I was limited to recommend only ONE thing to people it would be to do Tabata style exercise: http://en.wikipedia.org/wiki/High-intensity_interval_training
