Re:Biometric security
Because nobody could possibly figure out how to make a fake photo ID?
That requires far more effort than just downloading an SSN and DOB, especially faking a modern ID with holograms, embossing, and maybe an embedded chip. It also increases the legal consequences if you get caught.

Re:BMI is a lie!
Really? I think the following people aren't overweight
From looks, that too clothed? How is your opinion any useful?
For a metric to be successful, it should be fit for a purpose. The purpose of BMI is NOT to tell whether a person looks overweight to Alomex when appropriately camouflaged in clothes.
The purpose of BMI to be an easy to compute formula for easy to obtain raw metrics to determine chances of disease. It is a difficult problem to solve. If the only objection to BMI is that overweight people according to BMI "look" non-overweight to you, that is a great metric.
Do you have an alternative ? Equally easy to calculate on equally easy to obtain raw metrics with better chance of predicting lifestyle disease than BMI? You could win a Nobel. Though I guess like all nit-picking-non-Nobel-laureates, you just don't understand the purpose of things you are picking nits in.

Re:Used to be able to dream lucidly when ...
Some answers here... http://www.wikihow.com/Fly-in-... I remember reading an old Omni magazine article about influencing your dreams. For instance, to have a flying dream, as you're drifting off to sleep repeat to yourself, "Tonight I'm going to fly." I tried it then, and after a few nights of this, I was flying in dreams like Superman.

Re:Their first clue...http://fakefossils.webs.com/ fake fossils are possible. http://www.wikihow.com/Make-Fo... How to make fossils. http://en.wikipedia.org/wiki/L... Guess what: you can make plaster from limestone, sand and water. So you yes you could actually make a fossil of a Funnel cake.
Lime plaster is type of plaster composed of hydrated lime (slaked lime), sand and water. Lime plaster is similar to Lime mortar, the main difference is based on use rather than composition. Traditional lime plaster also contains horse hair for reinforcement.
So can all of you who are ignorant and offended go to reddit, 4chan or digg please. Thanks.

Re:Former "addict" here
Switching the stickers isn't the only way to screw one up. It's also easy to make an unsolvable cube after taking it apart with a screwdriver. The wiki-how guide states 11/12 of randomly assembled cubes aren't solvable.
I could solve a cube in just under a minute. Rather than focus on speeding that up further, I worked on all the other puzzles that came out after the cube's popularity. Missing Link, Pyramid, Rubik's Snake...I still have them all in a big bag o' nostalgia.

Re:Survival rate under-estimated?
Peak acceleration (given in multiples of g) is relevant. Humans can survive impacts involving accelerations up to around 100g -- much over that and there is "no" survival (I think the peak estimate for a documented survival is around 105 g) and to survive that very much depends on how it is experienced -- uniformly good, non-locally over your body bad. Under that, a few people survive, usually damaged, with damage that reduces on average until you reach forces spread out enough and slowly acting enough that they can bring you to rest with accelerations on the order of 10g (100 m/sec^2) that most people can survive without more than bruising if the forces that produce them are spread out enough on the body. This is order of the forces/accelerations involved in surviving a car crash with seat belt and air bag and collapsible front end of a car.
There are actually howtos on the subject:
http://www.wikihow.com/Survive...
These are based on both experiences/circumstances of survivors, plus analysis of the physics. There are actually lists and well-documented accounts of survivors:
http://www.oddee.com/item_9696...
(plus many others). As the first of these two links suggests, water is marginally better than concrete, and frothy, air-bubble-filled water is better than flat, calm water. Landing behind a large, heavy object (falling directly into the splash) helps enormously.

Low on ammo? Hotdogs give better results anyway..
There's no need to waste ammo or even go all Monte Carlo on this problem, especially if you have a reliable source of cheap, low-grade meat. http://www.wikihow.com/Calcula... Read here about the grandfather of the above tutorial, the Buffon Needle Experiment: http://mathnexus.wwu.edu/websi...

Or...
...they could take the same sheet of aluminum, weigh it, cut along the arc that they already inscribed and weigh the quarter circle, and multiply the ratio in the weight by four. Or, they could take a length of string, carefully line it up with the arc they already inscribed and snip it, form the ratio of its length $\pi R/2$ and the length of a side of the square R, and multiply by 2. Or they could evaluate using any one of a number of summed series. Or any of a number of other measurement-based geometric arguments, most of which will be more accurate than Monte Carlo done with a Mossberg "corrected" by arguments that are surely more abstruse than summing a series.
If one absolutely insists on computing pi using homemade Monte Carlo, you might as well toss hot dogs:
http://www.wikihow.com/Calcula...
Or toothpicks, if you want a bit higher resolution. With a large enough target grid and a good enough "random toss" one can once again avoid needing to "correct" for the non-uniform distribution of pellets in a shotgun blast.

Re:Liking my old cars more and more.
But I can tell you that there have been at least 5 times when I was sure the lane next to me was empty but the blind spot light was on. 4 times, somebody had legitimately come into my blind spot from an unseen angle.
Are you sure you have your mirrors adjusted correctly? Many (most?) people adjust their side mirrors so they can see the rear end of their car, but better method is to adjust them so the images slightly overlap with the center mirror - as described here or here or here. (or Google: adjust car side mirror) This method eliminates all of the blind spots.
To adjust mine, I simply park on a long straight road and adjust each side mirror until the image on the inside edge just overlaps the image on the outside edge of the center mirror.
I just buy the little convex mirrors and stick them on my side mirrors. This way I can see anything to either side of me no matter where they are. I primarily got them for towing my boat but they work great for everyday driving.

Re:That's not the problem.
Up until the past 50 or so years, people who learned about Standard Deviation would do so in environments with far less stimulation and distraction.
They also did so in an environment where they had to do all the math by hand (or with a slide rule).
The math is not difficult. But it is repetetive in the extreme. So unless you were a savant you learned to pay very close attention to the numbers and what they represented. For those of you who didn't take statistics, here's a link to show you how standard deviation is calculated. With only 6 items:
http://www.wikihow.com/Calculate-Standard-DeviationImagine doing that, by hand, with a hundred items. And that is just finding the standard deviation.
Now you can get the "answer" with nothing more than copy-paste. And if that "answer" doesn't suit you then you tweak the input and get another "answer" a second later.

Re:Where are they?
Have you ever used a directional antenna?
I made one using a coke can and a USB wifi adapter and was rather surprised by the large number of additional number of hotspots I was able to see by slowly turning the can in my suburbia 2nd-floor bedroom. I wouldn't be surprised if my recycled-from-the-trashcan directional antenna increased range by 200% or more.
Since the normal range of wifi hits 500 feet outside, and wifi hackers have achieved as much as 30 miles (50 km) with directional antennas, it wouldn't seem untoward to hit a few miles with an expensive, pole-mounted directional antenna and relatively few obstructions.

Re:Efficiency.
Wow... just... wow.
Well, I'll bite back.(*)
Government takes out my brakes? No problem, shift into first and engine-brake going 10 mph down the hill.
Good luck with that at any speed which would have the potential to kill you
Any chance you're confusing engine braking (using the air that is pumped through the motor to dissipate energy) with applying the handbrake? Now, engine braking in first gear at high speed is likely to destroy your engine in addition to not being very effective, but I wouldn't think the chances of it killing you outright are that high.
At this point i'd like to recommend you practicing basic reading comprehension. No, pretty sure i don't confuse engine braking with the handbrake. Me not mentioning handbrakes at all gives a slight clue regarding this matter. My point is, you won't even be able to get the 1st gear engaged at any considerable speed (and if your do manage it, you destroy the engine (as you point out, supporting my point), likely destroying whatever was dissipating the energy before.
Get caught in a storm or drive into a lake? I can simply unlock the door or roll down my windows and swim out, no power components to sieze up or go inactive.
Car doors can usually be opened from the inside even when locked.
...except when opening them against a significant pressure gradient. Car doors often cannot be opened in a sinking car, whether they are locked or not. And even if they can be opened, leaving them alone and going for the windows gives a better survival chance.
So, you agree with me on the door matter.

You're driving manual and don't know how to engine brake? I got some ridicule for you right here. In my home country, you can't even pass the on-road driving exam if you don't demonstrate routine use of engine braking.
Uh, i was under the impression that i'm confusing engine braking with hand braking, now i'm not to know engine braking at all? You're not making much sense here, my dear friend. If you're representative for people in ``your home country'' then i'd much rather not drive there, thanks. I can go faster and safer here, anyway.
Maybe wanna try again?(*) Damn you are even confused about what was 'bitten' here. Protip: not people.

Streisand Effect, anyone?
Let's spread the news of how to beat polygraphs as widely as possible. Now we have the government banning it, that makes it desirable knowledge, OK?
From TFA: "Charles Honts, a psychology professor at Boise State University, said laboratory studies he’d conducted showed that countermeasures could be taught in one-on-one sessions to about 25 percent of the people who were tested. Polygraphers have no reliable way to detect someone who’s using the techniques, he said. In fact, he concluded that a significant number of people are wrongfully accused."

Facebook: a Network Effect virusThe Network Effect was heralded. Everyone on

.[In the middle of writing this post, my SO wanted me to "unfriend" some supreme PoS. No visible way to do this. Search Google. Go to this Facebook help page, appropriately called "How do I unfriend or remove a friend?". In attempting to follow the 3 simple steps, I go to that person's Facebook page and attempt to hover over their FRIENDS button. Of course they are not showing one. Back to Google. Follow this new link...interesting how Facebook says it is a 3 step process (that doesn't work, and requires *#&%^ Javascript) and the wikihow page says it is an 8-step process that involves finding the person on _your_ FRIENDS list. Not easy to find the FRIENDS list, even on your own page. Turns out it is under "Edit your profile". Bring up my SO's list of friends. Un-frigging-sorted! Can you believe that?!

Re:FB's not worth the hassle

It required doing some extra steps that I never would have known how to do. It is doable, you might need to google for that info now, and once you know how to truly delete your account, re-log in and perform those steps. Here's a quick Wiki-How link...

Some ideas
Lock incoming connections down by MAC address and disable your SSID. This will probably make them go away. Also, run WPA2+AES and pick a longish WIFI key.
If you have an ASUS Dark Knight router you can setup multiple SSIDs (guest networks) that disconnect every 60 seconds and name them "StopStealingMyWifi". This way you real SSID is hidden and your multiple guest networks are visible, but are unusable. You can also set hours of operations for your radios on the ASUS and turn off your radios at night and when you are not home. Lastly, if you are running dual band, turn off the 2.4 Ghz and run on the 5Ghz band. The 5Ghz signal travels poorly outside your home. WIFI is tough to secure with all of the WIFI hacking tools, but get a good router and rotate shield frequencies and should go away.
Lastly, here is an article on the subject.... this article disagrees with me on disabling your SSID and I am sure others will have an opinion....

It is possible to unbrick! I did it before
I'm too far down for this comment to really matter, but in general, it is possible to unbrick a failed BIOS flash. The reason is that already for some time all (or maybe almost all) manufacturers have two parts of the BIOS - one that gets updated, and a second part that never does, or maybe can't. The second part (actually it is the first), only has very rudimentary software. It can read floppy disks, but not much more than that. The idea is exactly that you can recover from a failed flash.
That means that to recover, you need to get the right program into a floppy, with the right BIOS on it. You then boot into this special flash mode, which often means pressing some key combination. I've done it on an LE1700 that I bought of e-bay, and I'm pretty sure you can do it on almost any computer.
In some more modern BIOSes you don't need a floppy, but can do it with a USB stick.
I'm too lazy to do a thorough search for the exact procedure, but here are two good links that I found:
http://www.mydellmini.com/forum/dell-mini-10v/18080-how-unbrick-mini-10v-using-floppy-drive.html (this will work also on other computers, I think)

The article is about Gmail taking the lead and one reason is that Gmail supports IMAP. IMAP can be used either to keep the mail on the server or download it locally.

Now if you have a lot of mail stuck in Hotmail it is a bit of work to transfer from Hotmail to Gmail but it can be done.

Re:That depends...Look here. Not exactlly hard is it.
Webkit is not without competition even on mobile devices, and given that Apple also has a serious stake in Webkit your argument fails. In any case there are several different browsers on Google Play, and on the desktop IE is still heavily used in a corporate setting despite its market share dropping all the time. Few corporations are considering Chrome, and as long as that vast market is using Windows desktops and IE, Chrome will not dominate anything.
I haven't glossed over SPDY at all but looking at it it appears to be an attempt at a replacement for HTTP and TCP. I don't see the one Google web server to rule them all anywhere. Do you think Apache, Microsoft and any of the other web server developers will do exactly what Google wants if they start trying to exert any pressure? Besides which SPDY is a fully documented open protocol. It's hardly SMB or
.doc. WebM is the same. An open standard, not a patent-encumbered one or an undocumented, only works on one platform, one.This is nothing whatsoever like Microsoft's crushing of Netscape, pollution of Java, bullying of Intel and the PC OEMs, undocumented document formats, destroying small competitors, per CPU licensing and all the many, many other misdeeds and outright crimes that it committed and was convicted of in both of its main markets. You should try reading Judge Jackson's findings of fact from the 2001 anti-trust trial. You'll see from that that Google has a very long way to go to catch Microsoft in evil, let alone outdo them.

Re:Re-think seat position.Simply Google "distance from steering wheel", for example: http://auto.howstuffworks.com/car-driving-safety/safety-regulatory-devices/airbag2.htm
Researchers have determined that the risk zone for driver airbags is the first 2 to 3 inches (5 to 8 cm) of inflation. So, placing yourself 10 inches (25 cm) from your driver airbag gives you a clear margin of safety. Measure this distance from the center of the steering wheel to your breastbone.
Or, http://www.nejm.org/doi/full/10.1056/NEJM199807093390219:
A limitation of our study is that the new regulation defines the safe distance as 10 in. (25 cm) from the breastbone to the steering wheel.
or, http://www.wikihow.com/Adjust-Seating-to-the-Proper-Position-While-Driving
Distance from the wheel: There should be a minimal clearance of 10" (and preferably 30cm) between the center of the steering hub and the base of the breastbone (sternum). It should also not be further away that 45cm.
For me and my height, that results in *almost* (but not completely) straight arms in addition to being able to control the pedals properly - not too straight or bent - either is problematic in an accident. Other pages document an ideal arm bend of 120 degrees.
