How can we learn to throw a basketball into a tiny hoop from far away without having very accurate estimates?
The answer, IMHO, is in the question - "we learn". We do the learning until the brain remembers to link a visual pattern with a muscle activation pattern that gives a satisfactory result. The good bit in all this is that the pattern recognition fortunately is flexible enough to learn a few major patterns and be able to more or less accurately intrapolate and sometimes extrapolate to approach the goal in a somewhat different environment. When the matching->activation cycle "fails" brain learns (has to learn) a new pattern. Some learn it (the ball throwing pattern) quicker, some just cannot - their brain "machinery" is just not tuned for those tasks.
Think of any sport and just how many good estimates are done VERY quickly and pretty damn accurately.
Well, even though the result for some:-) who tries is "pretty damn accurate", for a lot/most it usually is not. Those who do it accurately learned certain patterns to consistently, more or less, recognize them, extrapolate, and execute the appropriate neuron firing patters to reach the goal.
The missing key here is probably this - while it looks the "estimate" is accurate, a brain does not really "know" where the target is. Unless another pattern is learned - match visual pattern with an "abstract" (for a brain) concept of a distance.
The information is never "lost" it's just unavailable for a time.
That would be really nice, but unfortunately it is lost forever and ever.
If it was lost you wouldn't have the "oh yeah" moments when you remember it or look it up again.
We are fortunate that (and for some "if") enough of a pattern remains to recognize the same or similar bits in the future.
A counter example: déjà vu - a brain pattern matching machinery becomes so thoroughly confused:-) that it "matches" an event that has not occurred before...
There is no real reason in the survival of the fittest terms for us to be able to accomplish such tasks. So those resources in the brain were put to use on other tasks like accurately processing visual and audio data
The keyword here is "accurately". It is simply not applicable at least not in a sense we used to associate with what machines are able to do. For our brain there is always a degree of uncertainty in the pattern matching. Sometimes the matching is so far from "accurate" that a matcher gets eaten:-)
open a Slashdot story with ~1000 comments and watch as the browser just stops dead in the water for 5-15 seconds while it renders the page
I'd try to disable/. scripts (if you have NoScript). And maybe FSDN too... AFACT, and it was my experience, that the lag is not a page rendering time, but a script on a page trying to connect to a slow server and that, unfortunately, in FF blocks page rendering.
This is not a win-win solution:-) Some page functionality will be lost. Arguably not a very important part of it:-)
This flips a sensor that activates a camera... The MCU parses the pixels...
Or they attach a couple of (IR, ultrasonic, whatever) range/distance sensors and measure the size of what's coming in. Then that $1.59 should be just fine;-)
The big mitigating factor of course is that China's own economy and foreign reserves depend on the health of the US economy.
It does. For now... "It's China's World. We're Just Living in It" - a recent Newsweek article - pointed out that China is forming the Asia-only regional reserve fund. Side-effect of China bankrolling it is that the deals are made now in yuan instead of dollars in that part of the world. The big question is this - how long will it take to transition from "depend on" to "one of the assets" to "why bother, lets collect the debt"?..
if he already knows that stuff, and is really asking how to get MPLAB working so he can program his PIC, well yeah then he's well and truely lost.
The "request for information" about controlling "bits" on a platter also brought up a file system... along with the idea that it, the file system, controls positions of those "bits"... "Truly lost" would be a nicer outcome, I'm afraid it is much much worse than that.
However, and due to the lack of a useful information in the request this would be a very wild guess, maybe he did not really ask about "bits" and about positions of those "bits". Maybe the question rather was about the writing to the hard drive bypassing the file system and the cache. In this case he only needs to read about O_DIRECT or "raw devices" while they are still in the kernel. That is if he understands, or is able to find out, that one cannot and should not assume anything about the physical layout (number of platters, heads, cylinders and sectors) of a hard drive.
Apparently, one of the absolute worst sites for the overall performance of Firefox is this one.
If you have NoScript in your Firefox, and it looks like you do, block slashdot.org from running its scripts. This will disable dynamic index - if you ever cared about that functionality), - but the speed of site rendering will return to the more or less expected level.
I don't see why shifting the managerial focus to commercial enterprise will do anything to advance pure science.
It depends on what your scientific endeavor is. Is it a science of space flight? Or is it a science that you conduct in space and you just need a ride to get there? You are absolutely correct if all we are talking about are different delivery mechanisms - conventional rockets, high altitude assisted launches, scram engines, The Elevator, etc. If those are the subject(s) of the scientific research, then definitely (IMHO) a commercial enterprise will not help you a whole lot (if at all) today.
However, if you send humans into space to do science in some lab up there, on a moon, on Mars, etc., then whoever delivers your scientists to the lab is not much more than a glorified taxi driver. Do you build your own car to commute to work? Actually, if I remember the history correctly, some people in the early days of automobile did just that - built their own cars. But nowadays if you do not have your own car you hire a taxi. So extending this analogy as far as I can;-) Lockheed and Boeing are your local car/truck rental agency - U-Haul maybe;-) or "Two Guys and a Truck" (because they actually deliver stuff to orbit, almost every other week). Alternatively you can hire a truck with a Chinese or a Russian or (some time later) maybe even an Indian driver.
I always heard "You can have it fast, good, or cheap, pick two"
And yet, while well known, it is a gross oversimplification. For instance, "fast, good, but expensive" is also known as the task of making a "baby in a month by 9 women";-) Unfortunately the solution of the "fast, good, or cheap" is much closer to 1 than to 2.

because it's not like we don't have any siblings with kids or friends with kids or were kids ourselves
A car analogy;-) Do you remember the time when you were not able to drive yet? But you had a pretty good idea, right? Because your parents had a car (or cars) and some of your older friends did drive and you've seen many times how it is done and knew all the intricate details about driving. Then you started driving... Do you recall those first few times? And yet you had a pretty good idea. Same with kids. All of us were kids;-) and many had siblings with kids, and we new families with kids and had heard their stories. Then our own kids arrived... and sleepless nights and worries and seemingly perpetual attention they needed (at least in the beginning). Knowing and experiencing are not quite the same.
PS: Another interesting (and IMHO vivid) analogy would be sex;-)
I caught a 9AM showing on Saturday. Surprisingly few single guys there. Mostly middle-aged couples.
Just a guess - everybody else is either still in bed or just woke up;-) And, another guess, it probably would pay not to be a pessimist this time - it was even more enjoyable to see a good movie when "the Damn Kids" were enjoying it too. It was fun to observe 4 (18ish) girls trying the "live long a prosper" gesture that they learned by the Spock-to-Spock scene. Talking about "Generations"...;-)
in fact, it would make people stop using their heads
Certainly, because patents and profit are the only factors that would motivate a person...
Without a patent, everyone would just use the 1st method and nobody would want to improve upon it.
Note how badly we, the humanity, had to struggle before July 31, 1790 - same stone wheels, same obsidian tools, same clay tablets (or were they invented and patented later?), etc...
For instance, ROKR Z6. It connects to PC via USB as a memory card (one of the options). JARs copied over to the phone are installed with a single click;-) Out of the box it has a little over 60M of free space with an option to add (up to) 2G micro-SD card.
Phone is easily reflashable including mods that add telnet and FTP;-)
teams have to get their device to hurtle up a 100-metre-long ribbon, suspended from a crane, at an average speed of two metres per second
at 2 meters per second it would take a little over 4 months to get to geosynchronous orbit
2 m/c is an average speed over 100 m climb, which starts at 0 m/c. Assuming constant acceleration to the mid-point and the same (only for simplicity;-) deceleration it should take a little over 8 hours to arrive at the intended destination... You may find it acceptable if you read a book instead of listening to the music:-)
