I'm developing a slow but very secure RSA cipher that treats your binary data as one large number. It will take the digits of this number in base m (where m is the modulus) and salt and encrypt each digit. This produces a data block that is encrypted using only one cipher. This eliminates the symmetric hole altogether, even though that hole is rather small. My new technique has value bacause the symmetric hole is still one of the biggest holes in the entire PGP system, next to implementation specific vulnerabilities.
The Handbook of Applied Cryptography: http://www.cacr.math.uwaterloo.ca/hac/ is a very detailed guide to some cryptographic algorithms and theories. This is not for newbies at all. For those wanting to implement a particular cipher, this book is the place to refer to. On top of everything, it is free.
Gaston Julia, from circa 1920, investigated fractals before Mandelbrot. His work is the basis of Mandelbrot sets as the points in the Mandelbrot set are exactly those parameters for the corresponding Julia sets that are connected. If anyone should attribute fractals to any one man, Julia is more pronounced than Mandelbrot. Granted, Mandelbrot popularized fractals but the analysis stems from Julia's work.
If they still make Capsula sets, try getting one. They are modular units that allow one to create mechanical devices and vehicles. I don't know if they are still being made, but I used to love them when I was a kid.
That is why i'm going to have a code prepended to each identifier. This will look extremely ugly but the premise is that there will be a certain number of characters, about 6 for 56800235584=(62 = 26 + 26 + 10)^6 unique identifiers. I originally thought that 30 "digit" identification "numbers" be prepended. But a later thought is to have a total of m = (62^30 + 62^29 +... 62) identifiers. This can be done because the underscore is not in the 62 digit character set and can be used to denote the end of an identifier. I would use about three (n=238328) or four (n=14776336) digits followed by the path and function name. This should make it portable to all compilers.
Centrinia has a base library that is written in C. Since C does not have namespace features, I did the next "best" thing: explicitly have the entire namespace in each global identifier. Take a look at my web site at http://www.student.gsu.edu/~zliu2/centrinia.html to see my rationel. An example of my natural number routine name is
I like to use "shred/dev/hda". That takes time but it is worth it if you know you will never use that hard drive again, such as when you leave a company. If you are in a pinch, you can first do a "cat/dev/zero >/dev/hda". You can also use "dd" or "sdd". If you want to erase a magnetic medium, zero out the media first and then use "shred".
I am a student with a dialup connection at home. The only way I can possibly install most software is by compiling "fetch lists" and then fetching files from the school connection. The easiest way to get FreeBSD is to download ISOs, the second easiest might be to wget the entire FTP directory. The second method is very rude and so I use the first method. There are many people who have access to a fast connection only at certain times. Also, I have a laptop that runs Mac OS X. Furthermore, everything I access on the internet goes through this laptop. That means that can only install via files and not with any kind of a network install. Downloading ISOs is not much of a waste of time as I have it downloading on the background. In this case though, I it is a waste of media as I have two obsolete CD-Rs.
I just don't like it when I have to go through all the effort of downloaded 1.1 GB of data and burning two CDs just to find out that they are obsolete. What I hate more is when most people tell me that there won't be a new release condidate and I can rest assured that RC1 is going to be the final, and later find out out that there is a RC2. Thanks for the advice of writing to CD-RWs though. I'll try that since you probabilty have installed operating systems that way. I was afraid that there would be read errors and the second to last thing I want read errors in is an operating system install disc (compressed personal work being the first). I think I will just stick with 4.10 for the next few months just to see how 5.3 pans out.
You mean I just made a coaster and a frisbie? I just downloaded RC1 last week and burned them onto two CDs. Now I have to wait for 5.3 to come out before I burn two more CDs. By the way, does anyone want two used CD-Rs?
I don't like it when they tell me that RC1 is most likely the final release candidate and then release another release candidate. I might just stick to 4.10 for the near, and possibly distant, future as I have heard of some performance slowdowns in the 5 branch when compared to the 4 branch on single processor machines.
Knuth's Computers and Typesetting material should be taught to students who want to learn about documentation. Knuth's writing style is very straightforward and direct. Every student who wants to develop a well documented project should at least scan over one of TeX or METAfont program books to learn how to document code. The two programs also deal with orginization, making the most of a given implementation, and good general natural language composition in general. All students who want to pass on knowledge to others should learn from Knuth's example. Knuth is an excellent teacher. I can make that statement from just reading his books. Anyone who want to write clear and concise papers, programs, books, and anything that is meant to teach others should at least study some of Knuth's works.
As I understand it, VASIMR and other plasma based systems require megawatts of power. I wonder where they are going to find a dense energy source that can provide that much power. Consider that the space shuttle only requires power on the magnitude of kilowatts. It would be interesting to see a nuclear powered (think submarine, not actomic bomb) spacecraft because that might be the best way we can put a dense enough energy supply on a craft.
I just downloaded the ctss-listings.zip file with Bit Torrent and have posted it on my school account. You can download it here. I don't think that this server can be slashdoted so feel free to use it as much as you want. By the way, I was able to cut down 2 megabytes my switching over to the bz2 format. Nothing was lost here except for some redundancy.
Here is the shameless plug: my project is here. Spread the word.
I used hypergeometric functions to solve the equation
a x^b + c x^d + e x^f = 0
where the exponents are integers and the coefficients can be complex. I tried to generalize it for complex exponents but I quit after a while. Google should provide some preliminary information on using hypergeometric functions to solve the quintic
a x^5 + b x^c + e = 0
where c is less than 5 and greater than zero.
This is an analytic solution to the general trinomial that I found empirically (without proof). If one wants to solve to solve the quartnomial then two dimensional structures, quintnomials need 3 dimensional structures. This was computationally taxing on me and my computer so I didn't even consider the quartnomial equations.
By the way, I have implemented a Jenkins-Traub algorithm not so long ago that gives numerical approximations to general polynomial roots. It is fast and well known.
Subversion finally has a fully stable base if I'm not missing anything. The prerelease of APR has been giving me headaches when I have to install Subversion. Hopefully, Subversion will make another patch release soon.
Most Internet users between the ages of 18-20 are college students. It is also Dorm Storm month so the figures will definitely show a bias toward broadband use.
Most people generally assume a certain mindset of what is good and bad. That being said, I assume that this piece assumes the mindset that life, liberty, and the persuit of happiness are good while denying those things are bad. Now we have an axiomic system. So let's begin.
Communism is bad because it denies life. Communism denies life when it allows for dictators, time and time again, to slaughter 50 million people in a single reign. It denies life when it establishes people like Po Pot who also slaughter tens of thousands. It denies life when regimes constantly ignore basic safety and allows for people to die or get maimed. Communism in itself denies the value of life by stating that all life is equal, therefore making the least common denominator become the worth of all life. All communist states have a general atmosphere where life is worth less than in more civilized, capitalist, societies. Communism denies life.
Communism denies liberty. The least common denominator mentioned earlier can be either the traitor or the criminal, both the same thing in communist states. By assuming that least common denominator, people are treated as criminals in a communist state. People can not escape, they can not express their own opinions, they do not have self-determination, and they do not have any liberties as we know them. Escape is by far the most important liberty. Communism denies liberty.
Communism denies the pursuit of happiness. The only pursuits allowed under communism are those that benefit the people. The benefits of the people are determined by a select few. It is therefore a fact that communist states do not allow for any other pursuits outside of those approved, by the state, that benefit the people, and not individuals.
We have disproven that communism is good by showing, under every axiom we have, that communism does not meet those axioms of being good. We have to now prove that assuming that communism is bad is not biased. If everyone shares a value, then to share that value would not be biased. In this case, everyone shares (or should share), the value that life, liberty, and the persuit of happiness is precious. Is the assertion that everyone should share this value tyrannical? I say yes. Life is oppressive. We can choose, with certain philosophies, which tyranny we should live under. All people must live under the tyranny that life, liberty, and the persuit of happiness should be respected. That being said, since all people must share the above values, there will be no bias in asserting the stated axioms. Since we have shown that communism is bad under those axioms, it is not biased to say that communism is bad. I would have to say that those who disagree are biased. They are also against good. Thank you for listening to this tyrannical point of view.
I must say that the saddest movie I've ever seen is Star Wars Episode I. I'm still depressed after these 5 years of seeing my childhood memories raped like that.
Even if there were super-civilizations, they have to overcome the little technicality about not being able to send things faster than the speed of light. I believe that there are many solar systems in the universe that contain intelligent life. The only problem with finding them is that they are too distant. I know this has been said numerous times but I believe it to be true so I will say it again.
If there was a civilization that can send objects faster than light, they most likely would have been able to escape this universe altogether. This seems to be the most likely scenerio because the only thing that we know of that could possibly move faster than light is space-time since inflationary theories point at the universe expanding faster than the speed of light at some point in the past. The point is, if there was such a civilization, they would be advanced enough to employ a non-interference directive for every other civilization below type 4. All in all, either the civilization is too primitive to reach us with any means or they are too advanced to go around bothering us.
This is different. I think that having corporate support behind DVD viewing in Linux legitimizes it more. No longer are we using DeCSS based software in this case. We are now using a commercial product that even the media companies (film studios) support to a degree. I think this is a very good thing that Linux is getting support in an area where it has become criminal in the past. I would recommend the preexisting media players, such as mplayer and xine, over PowerDVD because of stability, ease of use, and performance. Of course, I've never used PowerDVD on Linux before. In any case, I hope that more companies back up Linux in these ways, instead of excluding Linux because of whatever reasons they might have.
As for two brain cels, I can tell you that that's almost enough for a motile being. I forgot the exact number, but some worms have very very small central nervous systems indeed. You can't do anything with only one, but with two, you can communicate and control even more nerve cells. Heck, a jellyfish doesn't have a brain, just a nerve net.

Sony is developing OLEDs. But Sony is also trying to infest the market with DRM technologies. So I bring back an ad hoc poll from a few years ago:
Today, Sony is
a) Good
b) Bad
c) CowboyNeal
I choose CowboyNeal.
