Remember when you were a youngster and you had to learn about O() ?
Well, over the years you lose sight of the importance of that.
Not too long ago, just for fun, I implemented a DFT naively, O(n^2), and as an FFT (O(n log n).
Try that and run it for 65536 points and see what happens, even on a fast machine...
Consider for example the humble matrix solver. Iterative solvers (only applicable for certain problem spaces) can get you n lg n sort of behaviors, as compared to n^3 for generalized gaussian elimination.
aargh. so, since I just finished _accidentally_ moderating the comment redundant, can someone explain how you change your moderation when you click on the wrong drop down item ?
seems like a good addition to the FAQ, o my slashdot overlords...
and by that I mean the availability of all necessary information. The first thing that I noticed as I actually read the FA was that the bacteria start releasing chemicals to signal there intentions and/or state.
One of the reasons people make bad decisions is because other people will withold valuable information PRECISELY so that you will make a bad decision. Even if you are in a group that wants to do the right thing there is almost certain that important information lying outside your environment is necessary to increase your odds of success.
It is still a warning to be vigilant. The big corps are going to be involved in setting the standard, and they are definitely going to want these tracking mechanisms.
(it can cause lung cancer, like any inhaled smoke, and it seems to have a negative impact on higher reasoning skills when used heavily for a long term
remarkably there was a study not too long ago, and cannabis smokers were found to have LOWER incidences of lung cancer than NON-SMOKERS. The researchers were quite surprised, as they didn't expect this at all.
like all things it depends on what you're trying to do.
re: fixies. they are simpler and less costly. so if you don't have hills to climb, they're a great option. also, in rainy nasty whether you burn through chains and cog sets in a hurry.
fixie has a nice thick chain and simply tossing the chain ring and cog (just one) is relatively inexpensive.
so superior ? not really, but certainly practical. remember, as simple as possible, but no simpler.
for precisely the reasons outlined here. they operate very well at very high temperatures.
anything operating on a mechanical basis will have a finite lifetime. a billion cycles sounds like a lot, but not when everything is switching 10 million times a second.
so these things will never work as a replacement for transistors.
making things smaller will always result in greater leakage. there might be salvation in quantum transistors. however, see tunneling.
It's like someone going out, find a source of some contagion, coming over to your house and infect you with it.
Sure, it would be a good idea to quarantine if somebody actually did that, but on the intertubes such a thing can be done with impunity, at least when people are running windows.
you say that government wants to expand, but really it's an unholy alliance of government and private industry. The corruption of government by industry has made it less responsive to the needs of the government.
A government responsive to the citizens wouldn't be able to grow, or engage in such oppressive behavior without the backing of industry. Or don't you remember the military being brought out to try and crush unions ?
"But we had purchased a reactionless, inertialess drive from the Outsiders. You may have guessed their price. We are still paying in installments. "
I seem to remember that in one of his other stories, the figure is a trillion stars, which was the worth of an entire, technologically advanced, planet.
The world's uber capitalist talks about how the government should do this and that
Well if the f*cking free market was so teh awesome, we'd already be the world leader, now wouldn't me ? We're the goddamn free market capital of the world, next to Somalia, that is.

It's important to use the right algorithm !
other than the fact that I have to listen to so many people talk about facebook.
and get off my lawn !
before it got to slashdot ?
that's just lame.

It really is important that information be free.
It is still a warning to be vigilant. The big corps are going to be involved in setting the standard, and they are definitely going to want these tracking mechanisms.

However degradation of reasoning over the long term does seem to be a problem. not sure how much you have to smoke to see that though.
I have never seen someone stoned involved in violence.
I have quite often seen someone drunk involved in violence.
and I think that the stats will back me up on this observation.

also see mems.
not a good analogy.

doesn't have a chance of passing.
if it passes it won't be enforced.
enjoy our corporatic overlords.

I find I learn much more slowly if I can't discuss things with others.
maybe that's just me.
I mean the actual quality of the binding, etc..
I'd buy them more often if "premium" hardcovers didn't look like they wouldn't even last 10 years.
As it is right now I only buy hardcovers for authors I _really_ like.
Buying a hardcover for casual reading or the latest Clancy knock-off is crazy.
I seem to remember someone getting shot in a BART station and the shooter got about 4 years.
and he shot the guy while he was lying on the ground.
you miss the point. It would be as thought competing newspapers were able to SILENCE the competition.
Everything's fine if I can buy whatever newspaper I want.
It's not fine if I force one of the newspapers to use unreadable print, and then arrange so that it can only be sold 10 miles outside of town.
it's not obvious to me how you can have a habitat in space without being underground.
I guess you could just build thick-walled structures of some sort, but going underground seems like it's probably slightly easier.
release 1/2 from the sand
release 1/2 out to sea
Then we'll know, right ?
the real question is: why, if it was a known high-crime area, wasn't there stepped up patrols of police ?
that would be a deterrent too, and the better one.

If our science students can't find jobs, the problem is a GLUT of science education.
There must be a gap or we wouldn't CONSTANTLY hear about how we don't have enough science and technical workers.
alright, I admit it, maybe I should have thought about that a little more before posting...
oh, and that should be *sshole, not *asshole.
