The business line models are typically a bit more expensive though, and not necessarily any better than the home user line. For example, the Latitude D600 is, with the exception of a couple of extra mouse buttons, equivalent to the Inspiron 600m. If you're opting for a plain vanilla or no OS to begin with, then save bucks on the home user line and just wipe the machine when it arrives.
No they didn't - what they did do is figure out that increased temperature is not correlated to higher failure rates - the failure rates don't magically decrease as it gets hotter.
Easy, I'll explain with a much simpler example - when your lawnmower runs out of gas, the blade underneath still spins for a couple of seconds and continues to cut grass until the forces of friction bring it to a halt. At the instant when gas is no longer available, the blade does not immediately go from rotating at let's say 1000 RPM to 0 RPM, it takes some time. The RPMs are not maintained, they degrade, but it doesn't just ramp down to 0 RPM in constant time.
In a car, you can think of your wheels as the lawnmower blade. And as most lawnmowers have some kind of lever to actuate the blade, a car has a transmission to actuate the wheels. As long as the transmission is engaged (and I am speaking solely of manual transmissions, not automatics, which function a bit differently because of torque converters, etc) and the wheels are still turning, the engine is also still turning over (i.e. the crankshaft, valves, and all associated pulleys are still moving). Of course, since there is no gas supply, the RPMs will decrease and you will slow down due to the forces of friction of the components of the vehicle as well as air drag, but the engine is not effectively "turned off" until your wheels stop turning. Therefore, any systems which are powered by those pulleys, like your air conditioning compressor, alternator, water pump, and power steering pump, still work until the RPMs drop off to a low number, say below 500 RPM.
So when my manual transmission car ran out of gas on the highway a couple of years back, I kept downshifting and kept the RPMs around 3000, this kept my power steering functional until I got over to the shoulder and was able to safely stop my car.
And for all you guys in the US who think no one drives a manual anymore, I still do, and so does the rest of the world by the way. Automatics have long been an American mainstay and never really caught on anywhere else...
At least with a steering wheel you have to make 2 or 3 full revolutions to get the wheels at a full turn angle, with a joystick it would just be a flick of your wrist. Can you say flip over?
Running out of gas does not kill power steering. As long as your transmission is still engaged and you're still moving forward, the engine is still turning over and the accessory belts are still moving (i.e. power steering pump is still active). Those systems stop working when your RPMs drop below idle RPM.
Agreed - looks like the embedded software developer didn't follow tenet 1 of the soft dev. process, i.e. assume the user is an idiot. It should always default to some "safe" value.
Wouldn't be very useful info to anyone buying consumer level products as the boards in question are server grade. Also, Google saying that company X's boards are more failure prone could get them into trouble. Furthermore, if you have a server farm/data center, you should do your own research, but barring that, shouldn't expect others to do it for you for free.
As a former Motorola mobile devices employee, I can attest to that. All cell makers have provisioning, it is nothing new, interesting, unique, or patentable (in my opinion). Just another example of Apple thinking that it excretes golden feces...
The Razr's innovation was its physical form factor. At time of launch, it was touted as the thinnest flip phone in the world. The software was the same crap that was being loaded onto all Moto GSM handsets during that time period. I believe it may have also had a unique metallic keypad but don't quote me on that. Nonetheless, it had some of that magic that made the iPhone a runaway success.
The Razr was an innovative phone when it was released, no one else had a phone like it (similar to the iPhone when it was released). It was copied and mimicked ad-nauseam by a number of cell phone manufacturers. Motorola's problem is that they rode the Razr wave all the way back to the beach before they refocused any attention on R&D and their upcoming product portfolio. I worked for Moto Mobile Devices for 4 years, and towards the end, all the big wigs were telling us we had nothing in our 3G GSM product pipeline, and that's when I made the decision to leave. The Cliq, while seemingly a nice device that appears to at least somewhat compete with the iPhone, is by no means groundbreaking. It may help Motorola to start selling cell phones again, but I doubt it will bring them anywhere near the level of success enjoyed during the Razr centric times. To see them back on top, Motorola will have to continue delivering phones that best the Cliq and drive the market.
Anything that is done by man can be undone by man. Yes, the algorithms can be reversed, just not quickly. That may change, but security has almost always been about making the potential "win" too difficult to achieve. Think about it. In medieval times, castles and fortresses were built on top of hills/mountains so they would be more difficult to breach. Were they ultimately defeatable? Of course, but the cost in either human lives, money, or both, was often too great to warrant an attack.
Some of the effects you mention are somewhat exaggerated.
Windmills have a much smaller surface area than say, a line of tall trees. The wind easily goes around the windmills and continues on it's original path.
Solar panels take the radiation energy from the sun and convert it to electricity. They are not anywhere near 100% efficient, so a lot of the radiation energy is still converted to heat when it heats the non-active portions of the solar panel.
The water exchangers represent changes so tiny with respect to the whole size of the oceans they cannot possibly have any real impact on ocean temperature (the melting of polar ice has a much more dramatic impact).
The salt water mixing is going to continue to happen irrespective of our taking advantage of the energy it produces, the same with the wind, and solar energy.
The diagram alone doesn't explain the whole story - the text it above helps...basically what is happening as a result of electrostatic forces and diffusion of the Sodium and Chlorine ions is that the capacitance of the carbon based electrodes is decreasing.
Since C = Q/V, or in layman's terms Capacitance = Charge/Voltage, it is easy to see that by reducing the Capacitance under a constant charge, the Voltage (work potential) increases. The net energy gain is the increase in voltage potential.

The Geek Atlas

· Score: 1
I found it to be much more useful than the standard Frommer's guide. It pointed us to lots of natural wonders (i.e. not tourist traps) and even suggested some good restaurants off the beaten path. What I liked most about the book is that it gave you a numbered guide of important things to see in each location, like having a personal tour guide (in many cases the guide pointed out things I would have easily missed). I think something like The Geek Atlas is a novel idea and would be interested to read its contents and visit the sites mentioned therein, but being an engineer who is constantly surrounded by science and technology, the things I want to see/experience while on vacation rarely have to do with those subjects. For me, vacation is a time to do something different, something out of the ordinary, something that is not part of my daily life. I'll take watching the sunrise over the top of a volcano over visiting the Hague at least 9 times out of 10...
Shall we go overly broad and say that because of that, we should incarcerate all humans?
Of course not. What I'm saying is that parents are primarily responsible for making sure their kids don't bring weapons/drugs into schools. If parents cannot reasonably guarantee to get this simple task done, then I'd rather err on the side of caution. I agree that what happened to the girl is wrong, but if I had kids in school, I'd rather have this girl detained in a room all day or sent home with police than have her freely roam the hallways. Can we at least agree on that?
Would you like to review your argument and get back to us a little later?
Sure. The administrators "did the search anyways" because there is already a precedent for kids bringing drugs/weapons into schools. Would you like to conjecture why these items make it into schools and who is responsible for them getting there to begin with?
Some may not want to hear this, but it's the parents' responsibility to make sure the kid doesn't bring weapons/drugs into the school. If the courts are ruling no searches of underwear, it's because parents should be aware of what their kids are stuffing into their clothing. The parents' lack of responsibility and accountability is the reason metal detectors and searches have become necessary.
No, they don't - my next door neighbor bought the cheap "rock salt" (sodium chloride) and used it throughout the winter, by spring his entire walkway was full of pits and cracks. I opted for the more expensive calcium chloride based pellets (I think the brand was Prestone Driveway Heat, but it doesn't matter which brand you get), and our driveway/walkways are still intact.
Indeed - for concrete, the cracking is worse, and harder to fix - also, the sodium chloride in the road salt would speed up the deterioration in the winter months. This is why manufacturers sell alternative ice melt for your sidewalk that is based on calcium chloride, etc.
Or perhaps the demand will create the industry/content. If California all of a sudden stops buying textbooks, the publishers will be more inclined to produce e-books...the money used for the textbooks could then be diverted into buying the reading device (Kindle, etc)/ebook licenses.
The Kindle or something similar is probably the right way to go - I personally would have preferred something like that as opposed to 40-50 lbs of textbooks in my backpack every afternoon.

Also been done before - the concept of signed binaries/config files is not new or unique to them.

Line the inside with aluminum foil - also easy to recycle and very inexpensive.

This might be slightly off topic, but for anyone interested in a good travel guide, I used the above mentioned guide on my last trip to Hawaii (honeymoon): http://www.amazon.com/National-Geographic-Traveler-Hawaii-3rd/dp/1426203888/ref=sr_1_1?ie=UTF8&s=books&qid=1248122652&sr=8-1.
