but, unlike your secretary not showing you things. you can just set up the filter to put the spam in a spam folder. you can then periodically look at it and see if there are any false positives. or you can tell the filter to delete things that are 95% spam, but put things that are still most likely spam in a special folder. that's what's great about learning algorithims, they can always adapt to what you want (if you teach them enough).
that's the beauty of this approach. the filter learns all the time (or atleast you can set it up that way). so if spammers get smart, it doesn't take long until the filter adjusts. what i'd love to see is this filter built into a mail client where you have two buttons for delete. one, just to delete the mail, the other to delete it and mark it as spam. when you press that button the filter would scan the email and update its rules.
while i fully agree with this article that we need to change our voting system, the american public will never get it. every presidential election year, i'm surprised how many times i have to explain the electorial college and how many people just don't understand it. now if we change the rules to a 'vote for more than one' or 'rank your candidates' system people will never understand how their vote works.
normally, i wouldn't mind that most people wouldn't understand, but you'd get the people who understand making tv commercials targeted towards the stupid saying things like 'voting second place for candidate b is a bad thing, put him third and put candidate c second.' it would be very easy to sway votes this way.
i wish we could come up with a simple way to find the best candidate.
my cs teacher told me this one back in college...he said one of the first runs of the f-16 (or maybe another one of the computer controlled fighers in the air force) they were flying and everything worked just fine. however they took it across the equator and the plan flipped upside down. so the pilot corrected it and everything went back to normal. then he flys across the equator again and it flips.
so they took a close look at the software, and there was a bug in their sin function so that when they went across the equator they angle changed from positive to negative and the sin function didn't have the negative incorporated. so basically when the plane went over the equator it thouht it was upside down and corrected itself by flipping itself upside down.
i think it's a funny example of a stupid mistake possibly making a catastrophe. i've never seen this mentioned elsewhere, so i'm not to sure about this. but i do trust the cs prof who told me, before coming to my school he did a bunch of government contract work.
i'll add another check in the positive column for netbank. they always have worked with whatever browser i ever tried it with. i'm currently using galeon with javascript turned off and it still their site still works!
my only complaint is that i get a little more spam from netbank than i would like. too many 'refinance you mortgage' or type emails. but other than that netbank is great.
actually smaller and slower is fine. i read a great article by richard feynman (i believe it's in the 'feynman lectures on computing' series). where he was talking about the theromodynamics of computation. if we slow down the computers and use much less voltage then we can get away with using a lot less power. with the added savings in power we can use more processors in parallel. it turns out that the way everything scales, you get more speed out of parallel processors and use less power. i don't remember all the arguements, it's been a couple of years since i read it, but if you find the book it's definately worth reading.
yeah, i'm sure that government stuff can't be copyrighted. i am a grad student and i get 100% of my funding from nist and the nsf so technically i'm a government employee. normally when you publish a paper you have to sign over your rights to the paper to the journal who publishes it. however, since my publications are a product of government money i don't have any copyright to sign over. there are extra forms i need to fill out when i submit something to a journal so that they know that it's impossible to copyright that specific article.
likewise with the official government transcript from the supreme court...it's uncopyrightable.
from as far as i can tell this isn't the official transcript...this is a transcript taken by someone in the audience. the official transcript taken by the people employed by the supreme court will be available in a couple of months (i think) and those are uncopyrightable and you can do whatever with them.
i don't think they mentioned the method in the article. but i can imagine using something like a neural network to learn the users' behaviors. from my limited work with nerual networks, i've discovered that they're really robust when they learn a problem. it's totally concievable that a neural net could learn irrational behavior too.
promotions wouldn't be a problem either. you have the network have a parameter for the type of job that a user is supposed to be doing. when they get a promotion that job type will change. their new behavior will not be marked as bad until the system learns the new behavior.
of course everything i said is under the assumption that they'll be using neural networks.
i thought it was licensed:123 or maybe licensed:321. i know it still worked about 2 years ago which was the last time i had a windows box. i haven't bothered with virus detection since i switched to linux
last year's physics nobel winners were very young...cornell is in his 30's or early 40's and weiman is in his 40's or early 50's. i don't know about the other guy, but i think that weiman was the oldest of the group that won last year.
nope....the oxidation of sodium is exothermic, and without the hydrogen it would just get hot. you need to have something to burn to get the explosion.
this is no good for the lake...when the sodium reacts with water it makes hydrogen (where the explosion comes from) and sodium hydroxide. so you're basically polluting the lake with a strong base (think draino). i wouldn't want to be a fish or a plant in that lake.
the lithium batteries aren't pure metallic lithium...it's just labeled lithium because it's a lithium ion from a lithium salt (don't know what the counter ion is though). a lithium ion is quite stable and you can't ignite it with water or air or anything for that matter.
it's not the amount of methanol that matters, it's the concentration? can you ignite a bottle of beer that's only 4% (i know beer's ethanol, but same idea)? can you ignite a keg of beer? can you ignite a vat of beer at the brewery? it doesn't matter how much alcohol you have, the fact that it's diluted in water will keep it from burning. i think (at least for ethanol) you need something around 50% before it'll burn.
they won't have too high of a charge (of course i didn't read the article, i could be wrong), i'm expecting something like maybe 12v at the most - and there definately won't be enough current to create an arc through air at 12v.
and if it did have a high charge, it still wouldn't explode. the reason you car battery explodes when you screw up is because it's a lead acid battery and the acid (sulfuric acid) decomposes over time and the battery leaks a little hydrogen. so a small spark (you can get a spark with a 12v car battery because they have very little internal resistance and can deliver 100's of amps of current) ignites the hydrogen and that's a bad thing.
actually the whole modem thing is right on their webpage...at least it was about a year ago when i was ordering dsl. to use a non windows box on dsl you need to get the external dsl modem.
but i will agree with you on the tech support front. they are the stupidest people i ever dealt with. it took me 2 months from the time i ordered dsl until the time the line was turned on at my house.
Well none of the bills you are referring to have become laws yet (except the DMCA). Fritz's proposed legislation and the one from today are just proposed to be laws. It takes quite amount of effort to get a bill turned into a law in the US. After a bill gets introduced, it then goes to a committee of a subset of congress to hash out the details. Then it goes to the full house (either the house of reps, or the senate depending on where it was introduced) for a vote. If it passes the vote then it gets passed to the other house and they vote on it. If it makes it through both houses in the exact same form then it goes to the president to sign. If he signs it, it's a law, if he doesn't sign it, then congress can make it a law with a 2/3 vote.
as far as competing laws, my guess is that by the time a bill get out of congress all competing/contradictory laws are identified and in the test of the bill they specify how it should be treated with all the previous legilation. But i don't know this one for sure.
no, you still get into problems with the frequencies traveling at different speeds (dispersion). think of an AM wave, you have a set carrier frequency and then you modulate it's amplitude to convey the information. you can take a fourier transform of the wave to see the component frequencies. if you do this, you'll see a large peak at the carrier frequency, but there will be other smaller side peaks (side bands) in there too. if you only had one frequency present, all you'd get would be a sine wave which carries no information. you need to constructivley and destructively add waves of different frequency to carry information. once you have more than one frequency, you get into problems with phase velocity and group velocity, and no matter how hard you try, the information will not travel faster than the speed of light.

nope....the oxidation of sodium is exothermic, and without the hydrogen it would just get hot. you need to have something to burn to get the explosion.
Na + H2O -> NaOH + H2 + Heat
H2 + Heat -> Explosion.

nah, it'll probably just blind you...i think you need to drink quite a lot to die.
what do you mean by 'output'? AA,AAA,C,and,D are all 1.5 volts. i can't comment on the current they provide though.
