I have a feeling that the physics needed to just go out and make your own nuclear bomb has got to be easier than that needed to make a quantum decryptor and then decode nuclear secrets. Especially when you can just photocopy the Feburary 1979 issue of the Progressive for a pretty good head start.
Yeah, I don't think big O notation works quite like that. My understanding is that big O refers only to the degree of the relationship between sample size (in this case keylength) and time. Going from a situation where it takes x*2^N seconds (where x is an arbitary scaling factor, and N is the length in bits of the key) to one whre it taxes x*N seconds is HUGE! Currently a 1025 bit key would take TWICE as long to factor as a 1024 bit key, with this quantum technique it only takes slightly longer. A 2048 bit key currently would take 2^1024= ~10^300 times as long, using quantum math it would only take twice as long. To put it another way, if a 2-bit key takes one full second to calculate, a 2048 bit key would take just over 15 minutes. Thats obviously a far cry from the microseconds to centuries relationship under traditional methods.
Since quantum computers may never be a consumer product, it's safe to say that no mere mortal would be able to make a reasonable secure code using public key anymore.
206 million years ago to be exact, but even/. obeys the speed of light.
Still, it looks pretty impressive for what has been described as a two swarms of gnats passing through one another, except for that each gnat is 15 miles from the next.
Not to mention the C|Net article that, well you better just read it: But a stolen copy of the source code is a far cry from a legal license to use it, Levy pointed out. While the latter would allow a company to market a competitor to Windows, the former would not.
Instead, it could provide aid to projects that are trying to reverse-engineer aspects of Windows. One example is a group called Wine working on technology that lets Windows programs run on Intel-based Linux systems.
Those pesky open sourcers stole it! I knew it! When will this anarchy end?
I would assume a lot of the problem with the apparent refresh rate is just an artifact of the video camera, which has much less persistance than the eye. Vector displays of any sort don't usually show up well on video, in the same way as 30fps film.
The asteroids idea looks good, but just how does the person get instantaneously transported to the other side when they move off the edge?
Umm, might want to check your facts on mpeg compression.
MPEG-1 is the first compression format created by the motion picture experts group. It was designed for a bitrate of 1.5 MBit/s (same bitrate as an audio CD.) The audio is compressed using MP3.
MPEG-2 is the format used in DVDs. MPEG-2 was designed for use at high bitrates.
MPEG-3 never got off the ground. MPEG(the group) decided that the goals of MPEG-3 were met by MPEG-2. The MP3's we all know and love refer to MPEG-1, Layer 3, the portion of the MPEG-1 format that stores highly compressed audio.
MPEG-4 is sort of a combination and improvement on MPEG-1 and -2. It works well over a higher range of bitrates and is somewhat more efficient. It takes longer to compress.
PSX2 supports MPEG2 compression because that's how DVD's are compressed. There really wouldn't be much prohibiting a game designer from writing their own mpeg4 decoder, although it might not be fast enough. Hopefully that would be an option....vheissu.../* This post not warranteed for use in misson-critical applications */
Ford executives today declared the much maligned Pinto to be entirely safe and sound.
"If people operate the car in a safe manner, it will be safe." Ford CEO Henry Edsel Ford IV said in a press conference today. The Ford administration cited a lack of customer education, and claimed that "The risk is much greater in the customer's mind than in the real world" "For example, a basic precaution all other traffic should be avoided, reducing risk of rear end collisions. Reverse gear should never be used, as the risk of colliding into stationary objects is much greater while backing up. As part of the final dealer checkup, we are careful to remove all fuel from the tank. Customers should be advised that they fill the tank at their own risk."
Other safety precautions cited by Ford engineers included the cars ability to move quickly and make sharp turns.
"Since it is a moving target, it is much harder for no-good-niks to hit. For this reason, we were able to ignore the need for any sort of structural protection."
The internet2 was created by a bunch of univeresities just so that it wouldn't be burdened down by people doing things like this. The whole idea is that it not be used for commercial traffic, and will therefor remain generally uncongested and available for research.
I don't think that good race car drivers really think about dying too much, at least on the track. They only reason they don't push it 100% all the time is to save gas and tyres (especially important as more teams go to reduced pit stop programs), and to a lesser extent, to reduce fatigue. These guys are professionals; they know the limits of their cars and have firsthand experience of what happens when they push too far. They don't brake when they're scared, they brake when they have too, and no sooner. Kahunas in F1 only put you in the gravel pit (or the Mediterranian.)
just my 2 mojo.
I'm not sure how a computer could do in NASCAR until an open-source Skoal processor is devoloped. The current systems are all proprietary and with Uncle Wil's leg broke, he ain't able to come and fix it too quick, costing valuable pit time.
I dunno, I see a lot of sign pointing to the immenent distruction of mankind, and we've pretty much invalidated the "We've made it this far" argument.
But then, that's just me.
Uhm, organic in this context just means that they contain carbon, not that they are from actual organisms. This is the old chemistry sense of the term that divides everything up into organic, carbon containing substances, and inorganic, encompassing everything else. Plastics are almost entirely organic compounds of one form or another, as well as most synthetic (and natural) fibers, petroliates, and Twinkies.
And before I read it further down, could we make a Beowulf cluster out of smart Legos?
Yeah, but you have to get grants somehow, and "It's simply a natural question to ask and a beautiful problem" just doesn't cut it for the streamlined, 50% less budget NSF that they last few sessions of Congress have left us with.
Also, encoded in morse code (or just 8n1 ascii) through successive miscapitalizations. DECss = 0/short, DecSS = 1/long. Pauses could be encoded as DECSS or D/CSS (for word and sentence pauses, respectively) Personally, I prefer ascii, just so that we can be ensured precise rendition of special characters.
It's spelled DeCSS!

Get it all into a fault-tolerant RAID system with hot swap and quadruple the cost. You still have only $2000/month debt service.

Statistics can't tell us what will happen, or even what has happened. It can only say what is likely.
Our first man could conclude that he is likely to be the last, however, what are the chances of being one of the first humans? Their estimates must be combined with the estimate of everyone who lives after them, if you want to compare systems of estimation. If you win the lottery, is it fair to conclude that everyone wins the lottery? A statistical analysis of two separate pieces of data will indicate two separate things. Obviously the one with less data will be less likely to approximate the truth; later data may even prove it's conclusion impossible.
In your dice analogy, you confuse things being more or less likely with what we would be statistically valid in conluding is likely. The likelhood of rolling the "doomsday" roll never changes. What changes is, given the data, what we should conclude the probablity of rolling the "doomsday" roll is, through statistical calculation. I agree, this does go down. The actual probability *never* changes thought.
The urn argument would be better phrased as: Say you want to be 90% certain that you're estimate the lifetime of the human race is correct, and you can put an exact number on the age as of now. You can be ninety percent certain that the human race is in the middle ninety percent of its lifespan, with no additional information. Therefore, we will not die for at least five percent of the total lifespan, and we will not live for more than and additional ninety-five percent. If you want to be 99% sure, you have to widen the boundries: we have at least 0.5% left, and we have expended at least 0.5%.
So I as part of the human race have a right to do whatever I want to any other member of the human race. Just because a particular group is part of a larger group doesn't give it unlimited rights to do whatever it wants to anything else.
Perhaps our actions would be 'natural'--they certainly wouldn't violate laws of physics, but that doesn't mean they are right or defendable as just. As soon people start realizing that a few extra neurons doesn't mean they can permanently and irreversibly change absoulutly everything they come across, we might, along with everything else, might have a future. Until then it's only a matter of time until Earth (and, likely, anywhere we happen to go) become uninhabitable.
This is all explained elsewhere, but the key thing is, you don't know what's stored on your computer: it's encrypted using strong (ie massive prime) encryption, so even if you wanted to find out or use it, you couldn't. Further, you don't store a whole file, only a small chunk of it. And you don't know where the other pieces are, or what blocks you do have go with which files, or where each block begins and ends (although a smart user could probably figure that out from transaction logs) Not only that, but the people who published the information don't know where it ended up, and the people who download it don't know who has it store. (as far as I can tell, although it's beyond my to understand how that could possibly work.)
Not only that, but it's peer to peer, so there really isn't anyone the corporate world could sue. I'm sure there's some sort of computer based attack that could shut down or make useless the network, but that's (fortunatly) not how corporations work.
... when it was discovered that that amount was significantly more than existed in pure form in the entire world at that time.
I suppose a reliable copy editor/sentence parser (perhaps using neural nets or something) is far too much to ask of slashcode.

In Genius , the Richard Feynman biography, there was an anecdote where the scientists working on the nuclear bomb at Los Alamos discovered they could requesition *anything* from the army. After asking for and recieving a 12 inch diameter solid sphere of gold (later cut in half and used as a door stop) they asked for a kilogram of osmium, only to be turned down when it was discovered that that significantly more than existed in pure form in the entire world at that time.

Pretty exciting stuff, until you get halfway down the article and discover that they made it with buckyballs. Doen't eople realize that there is no large scale (ie greater than a few hundred molecule at a time) process for making these things, after more than 15 years! Sure they're amazing, but at thousands of dollars a milligram, there isn't much use.
When we can either a) find a large scale production method for either fullerenes or nanotubes, or b) make a proper nanoassembler, that will be one thing. Until then, all this talk is even less meaning full than those 1950s Popular Mechanics articles that proclaimed flying cars for all within the decade...
