Self-reproduction or self-changing of Web pages

Author	Message
kan.. #1 / 3	Self-reproduction or self-changing of Web pages I have developed a method for reproducing an exactly same or slightly different Web page as the original page, using a JavaScript program that is included in the Web page. This method realizes self-reproduction of a Web page. The detail is available from the paper in the November issue of ACM SIGPLAN Notices, and from the paper of the Summer Symposium by Information Processing Society of Japan. But, you can see the outline in the following Web page: http://www.--*.com/ ~kanada/reproduction/index-j.html Self-reproduction of programs, that means that a program generates the same output as its source program, is an old topic in programming. However, there is no practical value in complete self-reproduction of a program. Complete self-reproduction of a Web page seems to have no practical value too, but incomplete self-reproduction can be used practically. For example, a structured menu can be realized. A structured menu can also be realized by the Dynamic HTML, but the method using self-reproduction is more flexible. --- Dr. Yasusi Kanada Multimedia Systems Dept., Central Research Laboratory, Hitachi Ltd.

On the contrary, yours is one of the few practical uses of such self reproducing programs, since it can be used in conjunction with a javascript "mailer" (a small piece of javascript that prompts the user to press a button, and then goes ahead and mails, say, a mailing list or news group). When combinded in this way, and when the HTML is embedded in HTML mail or a usenet posting, not a web page, you have created a "javascript mailing-list/usenet worm". Now, as to whether a worm has practical value, well ... Gary -- Key fingerprint = 0C FB 60 61 4D 3B 24 7D 1C 89 1D BE 1F EE 09 06

I have corrected them, although there are several minor links that has not yet corrected. I am sorry for your inconvenience if you have accessed the page. I will correct other links tonight. --- Yasusi Kanada, Ph.D, WWW: http://www.st.rim.or.jp/~kanada/ Multi-Media Systems Research Dept., Central Research Lab., Hitachi Ltd.
