Security digest

"This site is dedicated to preserving the history of early computer security digests and mailing lists, specifically those prior to the mid 1990's. This includes the Unix 'Security Mailing List', through to the Zardoz 'Security Digest' to the Core 'Security List', i.e. those preceeding BugTraq. These forums are a valuable insight into the embryonic development of the field of computer security, especially as it relates to the Internet, and the development of the Doctrine of Disclosure."

Core war

"Core War (or Core Wars) is a programming game in which two or more battle programs (called warriors) compete for the control of the MARS virtual computer (Memory Array Redcode Simulator). These battle programs are written in an abstract assembly language called Redcode. The object of the game is to cause all processes of the opposing program(s) to terminate, leaving your program in sole possession of the machine.

...The game was introduced to the public in May 1984, in an article written by Dewdney in Scientific American (Computer Recreations)."

Computer history

Some online sources about computers’ history:

Old-computers
A .com site - features a collectors section.

Computer history museum
Missing some info but includes even robots.

Wikipedia pages about computers, home computers, and pesronal computers.
I found the ZX photo there.

Personal timeline:
Sinclair ZX Spectrum
Amstrad CPC 464
Acorn A3000
The first home computer with a RISC and not the PowerPC based computers as Apple stated in some ads (~1990).

Favorite “computing” device:
The Antikythera mechanism (research project).

Multitouch screen

And speaking about the GUI’s future, this is a video about Jeff Han's research. Also, here is an overview on multi-touch systems by Bill Buxton.
