Semi-protection:
* Is not a proposal to prohibit anonymous editing.
* Is not a proposal for pre-emptive protection of articles that might get vandalized.
In my opinion, software is not the problem. There are two other significant disadvantages in using old computers. Old computers have almost always old noisy fans which need to be replaced. Moreover, a 15" CRT display, six years old, is probably not very satisfactory, compared to a recent LCD panel. Keyboards are ugly and the mouse is full of dirt.
Buy two computers and a floppy. Label them "NET" and "SECURE". Do not connect the secure computer to network. Write and encrypt everything on the secure computer. Transfer via floppy.
Or read your mail in some old simple mailreader (Emacs mail mode?).
In this country (Czech Republic), communists censored everything. Many books were banned, all photocopiers were registered, Radio Free Europe was jammed etc.
It did not work. People who wanted to get the books got the books. People who wanted to listen to RFE hacked sophisticated antenas and filters. We copied books using typewritters and Sinclair computers.
During the WWII this country was occupied by Nazi Germany. Germans removed SW band from all receivers. People who were caught listening BBC or radio Moscow were executed. Nevertheless many people listened. You cannot stop one's desire of freedom.
I agree that any hierarchical database can be replaced by a relational one. But XML is not a database format in general. The data in XML file are mixed with parts of free text and the order of elements matters.
XML (SGML) was invented as a markup language - ie a method for inserting metadata into your plain text (for example Docbook).
Real programmers still use Fortran and Cobol.
For someone who reads tons of articles about Java and Haskell and who considers C++ obsolete, may be very surprising that large part of scientific numerical computations is still done in Fortran.
Do you remenber the demand for Cobol programmers in 1999 (Y2K)? The critical systems still use Cobol.
I live in Eastern Europe. My income is about $400 per month which is above average in this country. I have a university degree and am not stupid or lazy. I just live in a poor part of world. I cannot afford to buy any western books or subscribe to any magazines. Web is the only source of information that I have. Web completely changed my world because giving me information freely. I am extremely afraid that someday such scheme will be adopted.
What a nice idea! I am looking forward for a secure job in a very important small-animals sub-departement of the european-hate-free-enforcement-agency. There is a new bussines of registering web servers, issuig web publisher non-hate certificates etc.
Of course, mathematics _is_ complicated.
Eric is very good at explaining complicated things quickly to people with no previous mathematical education. You must read serious mathematical books for weeks to learn basic ideas or you can find the same in MathWorld in an instant.
I was a regular user of MathWorld for several years. The Mathworld is an excellent piece of work, I deeply admire Eric for creating this.
There is a LINUX kernel module for IBCS (Intel Binary Compatibility Services).
I use the module to run SCO binaries on Linux. Works like a miracle.
Unfortunately, strange processors (RISCs, Aplhas...) still exist with issues like big/little endianness.
There are many better methods - like commercials in newspapers, IRC, or just posting the secret phrase on Slashdot.
US governement uses this secret phrase nonsense to justify _censorship_. They want to prevent Americans from listening, not the terrorists.
I won't pretend that I can do Arithmetics.
Image has 10000 bytes (8bits each).
I suppose that I cannot afford to change more than 1 bit per byte, otherwise the image gets spoiled. (I know nothing about steganography). Thus I have capacity 1bit per 1 byte.
Then 10000 / 275 is about 40. I have to change one of 40 bytes / bites.
I do not know anything about steganography but I think that there is no general method to find a message hidden in a picture. If the length of the message is small enough compared to the length of the picture and the picture has some random noise in it (like every photography has).
A typical GIF contains tens of thousands pixels. Assume that I want to hide a short message (50 chars 5.5 bits per char ie 275 bits in total) it means that I must add a single bit of noise to one of 40 bites of data. How can anyone find that?
And what if I add the noise myself? I mean somethig like one-time pad cipher.
Just a personal note. I am not Swedish nor American. I agree with you that America is the strongest, coolest, happiest, oldest, most harmonical republic/democracy in the world.
But talking about civil liberties, Sweeden and Switzerlad are the countries I would choose to live in.
Slashdot Mirror
No way. He could sell the rights to his story to TV and Hollywood.

At least one (1) person in europe (i.e. Orwell) read the book.
George Orwell was British.

I wanted to be terse. But slashdot refuses messages that are shorter than the subject and/or written in less than 20 seconds.

I agree. I used the words "in general".

Just type "steganography" to Google or Altavista.
