Here is a partial list of books published online, that I happened to like enough to bookmark. I find that reading a book on the computer screen is tedious, I mostly use the online version as a reference.

Handbook of applied cryptography: http://www.cacr.math.uwaterloo.ca/hac/

Underground: (I actually haven't read this yet) http://www.underground-book.com/

Netizens: (only partly read this) http://www.columbia.edu/~hauben/netbook/

http://www.und.nodak.edu/org/crypto/crypto/army.fi eld.manual/

Big Breach: http://www.antioffline.com/bigbreach/

The Prof's Book: http://frode.home.cern.ch/frode/crypto/Turing/inde x.html

I have a lot of other links also, but my bookmarks have become so nested and folderized that many are lost in there, I really need bookmarks for my bookmarks . . . Anyway, I would suggest that if you find yourself looking for interesting reading online, you will find plenty. If you choose you can find scanned in pdf's of various works on newsgroups and in freenet, etc.

However, my advice is to use the 'net primarily as a way to figure out what to read, and become familar with the local public library. Almost all libraries have inter-library loans which give you access to huge amount of stuff. When I can't get a work that way, I fall back upon checking databases of used bookstore inventories -- http://abe.com/ and http://powellsbooks.com/ are the places I generally go to.

This is neither goal free nor 3-D, but this is both interesting and a response to a question posed by many people.

Also, we're already linking to random university professor's random pages.

The Geology Explorer is an educational game intended to teach the concepts and principles of Physical Geology.

Actually mammoths didn't die off as long ago as everbody thought. There was an isolated group on an island that survived until only 5000 years ago. The thinking is that being on a remote island protected them from hunting by man which is why they survived so long. Details here, including the quote: "...surprisingly recent dates on woolly mammoth remains from Wrangel Island in 1990, ranging between 7390-4740 BP. The finds were remarkable for two reasons: they indicated mammoth survival on Wrangel Island for as much as 5000 years after the last known date of mammoths on the Eurasian continent, and they documented the evolution of a distinct dwarf mammoth population on Wrangel Island." Other theories include a virus induced extinction , but I think it was man... To me, even more interesting is whether or not man killed off Neandertals. These guys were all over Europe for a very long time, and they were smart enought to fight back. A war with them would have truly been "World War One". There is so far only one possible example of a possible human-Neandertal hybrid , so their disappearance probably wasn't from interbreeding...Let's take a poll, did humans deliberately destroy neandertals or were they the original Homer Simpsons that just died out???

Um, my point. Lessee...oh yeah. The irony here is that my job on campus is 90% Java and %10 LambdaMOO. Even though I don't think Java should be taught in classes, it's still my bread and butter. But with my C++ (and decade of BASIC) experience and the promise of a great wage, I learned myself all the Java I needed in about two weeks. I looked at the client code that existed, I skimmed a textbook we had in the office, and mostly I looked at the online docs, but I'm far from needing a year-long course to pick up the necessary skillz. I think we could all learn a lot more if we could intern/apprenctice in the working world.

The latest version of my pretty little Java client can be found at this place, but keep in mind that over the summer it's constantly being broken and remade in preparation for Geology 105 each fall. It'd be interesting to see it Slashdotted, tho.

I also took a "self-paced" C++ course this spring and I was really glad that I already had the concepts down. The strange syntax items in C++ seemed to get in the way all the time, and I can't imagine how complete beginners would handle things.

As for your comment on moving to LISP later on, my professor had a great way of exposing us to a second programming language. He gave us a program in LISP that would solve the farmer-wolf-goat-cabbage problem and told us to translate it into Java. The only guidance that he gave was pointing to an on-line copy of Common LISP: The Langauge. It was a challenge, but most of us got it figured out. After that experience, all the LISP I did in Comparative Languages was a breeze.

Bzzzt. Thank you for playing

• Soviet One Time Pads
• A Summary of Cryptosystems Midway down the page, you will see that AT&T sold a commercial one-time telegraph. Search for Vernam.

I also believe that Walker sold US one-time keys to the Soviets, but I can't find a reference right now. And of course there is an entire book on the subject as well.

I lucked out. I've been playing games since I was 4 (Donkey Kong on the ColecoVision, biytach!) and programming in every BASIC I've found since I was 10, but just recently I managed to get what I consider my big break. NDSU hired me on to work with their Geology Explorer.

Basically a Java shell for the LambdaMOO backside, it's got a good mix of graphics, interface, AI, and MOO specifics. After a couple months, MouseListeners are my willing slaves, and most of the niggling problems I had coming in have been ironed out. Mostly I've been making the graphics both run fast and look nice AND be functional. Yay, me. Sure, I didn't actually make the thing, but in my opinion it's much harder to tweak someone else's code anyway.

Um, by the way, I wouldn't recommend using the Explorer in the next couple days. I'm in the process of revamping EVERY SINGLE CLICKABLE OBJECT on the planet, which means that about half the world is broken right now :) Silly me.

They actually do..

There was a robot, name of Dante II, which was tested in the Redoubt, Spurr and Erebus volcanoes, which are near Anchorage, AK.

A copy of their reasons for banning it can be found here. The only part I edited out was the name and contact info of the statement's author.

I'm not taking a stand (see my signature below), I'm just trying to make some more information available to y'all.

It is an arrangement of the alphabet, known as a Vigenere Square, in which each successive row is shifted one place to the left (In this case, some of the letters are shifted in position to spell the word KRYPTOS), with reference alphabets along the top, bottom, and side. Though used in many ways, this table is very often used for one-time-pad encryption. For example, if someone wanted to encrypt the letter "G", and the key they were using was the letter "F", he would just look down column "G" to row "F" and would see that "G" becomes an,'E'. Since there are 26 rows and column on the Vigenere square, any letter can be encrypted as any other letter depending on the key used.

At least Jim Gillogly claims to have cracked it. See the "KRYPTOS" thread in news:sci.crypt. This article announces the break. This one mentions an NY Times article (no URL). He says he plans to publish the solution in The Cryptogram, the journal of The American Cryptogram Association

The information says,

Though few persons other than the author know the answer for certain, many have contemplated the question. We would like to pass on what knowledge we have gained from our cryptanalysis regarding the message. It is probable, from analysis of the letter distribu- tion, that at least four separate systems of encryption have been employed: Digraphic, Poly-alphabetic, Transposition, and One-Time-Pad.

Good luck to any Slashdotters who try.

This Website has a bunch of information on the code, including a picture and a detailed description of it from the CIA.

If someone would please upload one copy of all the clients to ftp://corpse.acm.ndsu.nodak.edu/incoming/ Then It would be available for others to get here
