Personal web history

1992 Python existed and had socket code & GUI code (stdwin) First heard of WWW, used line mode browser to learn about it No mosaic yet; one graphical browser (Viola), no source code Interest piqued

First graphical web browser in Python http trivial w. Python sockets html 1.0 (?) - event-driven parser formatter - several variants line mode browser followed feedback to Marc Andreessen Python still has all these components (much evolved)

1994 I didn’t get CGI! –Mike McLay & Steve Majewski wrote first CGI module Eventually I caught up –Standard cgi module supports file upload &c

1995 I moved to CNRI Grail browser started –as demo for annotating web pages –anecdote: Bob Kahn didn’t get open source, withdrew source distribution HTML 3.2, Python applets

1999 last release of Grail (0.6) gave up against netscape & IE still useful for minority platforms URL:
