If the fault occurs, cruise control can only be disabled by turning of the ignition while driving â" which would mean a loss of some control and in many cars also disables power steering.
Public Service Announcement time from a decade-long car geek.
SHUTTING OFF YOUR ENGINE WILL NOT CAUSE YOU TO LOSE CONTROL OF YOUR CAR. You'll somewhat slowly come to a stop. You won't "endo". You won't flip over and crash in a ball of fire. Your wheels won't even lock up. Furthermore, once your car is moving at a walking pace, you no longer need power steering. Try it some time in a parking lot. And no, you won't lose your brakes, unless your braking system has been poorly maintained. Test this by shutting off your engine in your driveway and seeing how many times you can press the pedal before it suddenly goes hard. That's where you have lost braking assist. Even further: loss of braking assist does not mean you can't stop the car - you just have to press much, much harder.
What is dangerous: if the ignition lock on the steering column activates and you need to steer. This is why you should turn the key to the accessory-only position.
Braking or pressing the cancel button will not work
Second PSA:
BRAKING ALWAYS WORKS. With the exception of some ultrapowerful cars like the Veyron, there is an order of magnitude difference between the maximum torque your brakes can generate, and the maximum torque your engine can.
The key is that you have to stop safely but quickly, firmly, and completely, and STAY STOPPED until you've shut off the engine. If you ride the brakes, you'll keep heating up the rotors, pads, and brake fluid. If the brake fluid boils (or more accurately, the water in the brake fluid, since it's hygroscopic and people aren't good about changing their brake fluid as often as they should) or you exceed the maximum operating temperature of the brake pads (passenger vehicle pads are designed for "cold" bite, ie to be useable for panic stops), then yes, you will not have effective brakes.
Seems like when the robot steers his arms he also bends the waist leaning a bit into the turn.
You steer a bicycle at almost any sort of speed by leaning, not turning the handlebars. In fact, if you turned the handlebars without leaning or shifting your weight, you and bike would tip over to the outside of the turn.
Make sure to have the "outside" pedal down and put weight on that foot, which shifts the Cg of you and bike lower. Want some extra fun? Lean the bike while not leaning your body!
For any slashdotters looking for a somewhat nerdy form of exercise, you can't get much better than cycling, and I highly recommend looking into it! There are so many kinds of riding out there, there's something for everyone, even if you have no interest in competition. I do strongly recommend you NOT get a hybrid bicycle, however; the upright position is horribly inefficient and NOT comfortable for any more than a few miles because your weight is not split as evenly between your arms and butt as it is on a road bike.
Get a road bike from a store that will do a fitting session with you (there's a lot of biomechanics involved- the bars and seat both need to have their height and front-back position set properly), and save money in your budget for accessories clothing (a comfortable pair of bib shorts is essential, and clipless pedals/shoes make pedaling far more comfortable and efficient.)
This is FUD based on nothing. Google has said for quite some time that Gingerbread was available, that Honeycomb would be closed and only suited for tablets and that Ice Cream Sandwich would have the source available once it was released.
It's not FUD based on nothing. It's based on a massive violation of the GPL by every single tablet maker (or Google, one or the other.)
It doesn't matter if they said "we won't release Gingerbread source code" - they don't have that option. If I buy a Gingerbread tablet with GPL-derived work, and ask for the source, I must get it.
The concern now is that they'll pull the same illegal bullshit with ICS, and there will be precedent. As soon as the first ICS device is sold, if that person asks for the source and doesn't get it, there's a GPL violation.
One of the problems the eInk people had was that they completely constrained the market via hideously expensive development kits and a poor selection of screens. Only 1-2, low-resolution, nowhere-near-A4-or-US-Letter screens have been available. The only exception are 2-3 large-format readers like the Kindle DX and the Iliad Digital Reader 1000 (which was a miserable failure, in part because they lied through their teeth about the specs, especially battery life, which was miserable...a few hours at best, instead of "days" to "weeks"), but even those haven't come close to the size of a sheet of US Letter paper. PDFs are *barely* readable on them.

Look down that list of screen specs and you'll realize why e-Readers, aside from Kindles and Nooks, have been a failure.
Seriously, your point about exposing him to other things is fine but using Ender's Game as a parenting guide is beyond ridiculous.
The question posited by the Slashdot story isn't even "how should you raise a prodigy child?" - it's "how should you sharpen this tool?", and the insidiousness of that reminds me exactly of the book. Ender's Game is about turning a child into a tool, and that is exactly what is happening here.
I don't think the kid is a genius. I think he's a kid who has no social life, probably has no friends or play time with them or by himself. It's easy to see how the energy a child uses to develop themselves as a person could be focused to produce results like this, but I think the end result is that he won't be a person. He'll be a tool, one who will probably be plagued by mental health issues the rest of his lonely life.
You could possibly fit the entire American school system into him.
Except that he's highly focused on sciences. How about some history, art, music, or languages for a few years? Heaven forbid the kid learn something besides science.
Speaking as someone who works with a lot of very smart people focused in very narrow fields: the kid's going to be a lot happier if he has at least some general background.
Didn't any of you read Ender's Game? Remember how, among other things, Ender often longs to just be a kid?
Northern Canada is not really a first-world region. It's mostly empty, frozen land and remote communities of native people living pretty basic lifestyles. Not much in common with the cities in the South.
Given that Canada is an ally of the United States- no, they are a first-world country. Have been since the Cold War, which is where the term came from.
See, bet you thought "third world" meant something like "really poor", and didn't know that "first world" equals "with us", second world equals "with the commies", and "third world" equals "not allied with either."
Maybe I'd prefer to have an operating system written by a professional programmer, etc?
Without waiting years until a community effort reaches the same state, that is.
You do realize that there are millions upon millions of qualified individuals available to assist with such an effort, right? And probably on the order of between tens and hundreds of thousands of professional translators out there too, right?
This isn't kernel programming, where a very small number of people are qualified to contribute productively.
The amount of CFCs pumped into the atmosphere by asthma inhalers is negligible at best.
You mean by millions upon millions of people with asthma, using them weekly or daily? Let's remember that we banned the use of ozone-depleting CFCs from sealed refrigeration systems back in the early 90's and mandated their recovery, twenty years ago. This is a use where the CFCs are being purposefully released.
The inhaler industry has seen the writing on the wall for the last twenty years, apparently been given a free pass on the Montreal Protocol which banned CFCs, and apparently decided profit was more important than the environment all those years. The EPA is finally bitch-slapping them into doing something.
Further, CFCs have enormous impact on both the ozone AND they act as a 'super' greenhouse gas, much worse than CO2.
Do you seriously not see the irony in inhaler companies using ozone-depleting greenhouse gasses in their products? It's almost as bad as GE (PCB polluter extraordinaire) selling water purification systems.
There is a huge difference between an unlimited air race and a display airshow.
In terms of safety regulations, there damn well shouldn't be, because the regs are based on the chances of an aircraft hitting the stands.
The issue is that a 500mph unlimited racer with control issues can come down miles away from where the control problem happened and in any direction.
Then the audience needs to be "miles away" so they have the same protection as an audience at an "air show".
Oh, your audience can't see the race now? Too bad. At least none of them will go home in a body bag with an the tailbone of a 80 year old down their throat and an airplane propeller up their ass.
US Airshows specifically prohibit any trajectories towards crowds and have large setback distances from the "box" that the display is allowed in, specifically for this reason. Clearly neither was being followed, or this crash wouldn't have killed and maimed so many people.
Was the race allowed to weasel out of those regs by not calling itself an airshow, even though that's exactly what it is?
"Since current regulations were put into effect in 1952, there has never been a spectator fatality in an North American air show accident. Thatâ(TM)s a safety record that is he envy of the entire motor sports industry."
So much for that record. The same page says:
"Second, air show performers â" both civilian and military â" are prohibited from performing maneuvers that direct the energy of their aircraft toward the area in which the spectators are sitting."
So much for that rule.
"Third, the industry and regulatory authorities strictly enforce minimum set-back distances that were developed to ensure that, in the event of an accident, pieces of the aircraft will not end up in the spectator area."
So much for that rule.
I hope the FAA employees, airshow promoters, and airport employees who approved the airshow plan are all charged criminally. Sadly, that'll never happen....
Every O-S project starts somewhere, U.JS had a humble beginning - so has mine. They are considerably different in their goals and current implementation. I strongly advise you know the difference before choosing or listening to the dismissive people in this thread.
You think an "odd number" means "divisible by 3", which means you have a less-than-middle-school education in math. That's not a "humble beginning". You're simply not qualified for the task you've undertaken. For fuck's sake, you didn't even look at the wikipedia page on parity, apparently.
That's what worries me. I mean, Israel is second only to the russians and chinese for technology theft, but...good grief.

If a hedgehog tastes something nasty, the froth it up and spread it on their spines. It works - if you get pricked hard, you can see a bit of an allergic reaction around the pricks (the spines are not like porcupines, ie, they don't have barbs. They're just somewhat sharp.)
How can they evolve that knowledge? Or is it aggression that is evolved too?
The same way any other trait evolves- the ones that do it survive better than the ones that don't.

Did you read the article? The resonance could only be felt on one very narrow range of floors. The whole building wasn't shaking, which is what tuned-mass and active dampers are designed for. They're for countering earthquakes, wind-induced vibrations, etc.
The article concerns a workout which happened to hit the resonant frequency of the structure, which was properly designed.
The failure you linked to had to do with criminal negligence by the owners ignoring repeated engineering and construction firms who refused to accept design changes driven by greed (and were fired for it), completely repurposed building usage leading to gross overloading of the structure's strength, and then completely incompetent handling of obvious signs of structural failure (failure to immediately evacuate the building.)
For fuck's sakes, they removed columns for escalators, then cut into the remaining columns, then ADDED A STORY WITH POURED CONCRETE FLOORS *and* an air conditioning unit the building wasn't designed for. And then when the building started to fail, they just blocked off areas to hide it from customers because they didn't want to lose sales revenue.

White paint simply works.

Clinton's point is that white paint is cheap, easy, simple, reliable, has virtually no operational expenditure, and a quick payback. Installing ridge vents shares almost nothing in common with his solution.
Getting directions to places (ok, so you can get a GPS or use a smartphone, sure)
Store locations, hours, etc.
As another poster pointed out, this seems like more of an issue of self control. I would suggest starting out with a dd-wrt or similar firmware for your router, and a)setting no-internet hours (say, maybe you only have internet for 2 hours after dinner?) and maybe blocking sites you spend too much time on.
These mechanisms could be defeated in an emergency (such as suddenly needing to book a flight, car, hotel, etc to visit a sick relative or for a work trip), but enough to keep you from getting lost in the internet instead of a good book.
Another option would be canceling your wired internet connection, but having a tetherable cell. A pain in the ass, but doable if there's a sudden urgent need.
