24/10: Creativity & Coincidence: CERN, the Web and the Internet
With Ben Segal, CERN

                *** NOTE: WEDNESDAY, IN C4 ***

   Now that the Internet has exploded in popularity on a world wide scale,
   with a major component of its success (WWW) being developed at CERN, we
   can look back and learn a lot by examining its history of gradual
   acceptance at CERN and elsewhere.

   The Web was prototyped and promoted by Tim Berners-Lee at CERN in 1989-91,
   and accepted world wide by 1993-94. But of course, before the Web's appeal
   could trigger Internet penetration into the most remote and unexpected
   places, the US-developed Internet protocols had first to be adopted at
   CERN, as well as in other key sites in Europe and later in such
   influential organizations as the ITU and ISO in Geneva. This was a
   political as well as a technical challenge.

   Even before this, some earlier developments were needed to enable this:
   standards for computer systems themselves, and in programming techniques;
   standards in network and computer hardware; and finally a change in
   mentality, among both manufacturers and users, for them to allow, and
   nowadays insist, that their systems should be able to communicate freely.
   (Today, we see similar phenomena occurring in the emergence of Linux).

   A fascinating element in technological change is the factor of accident or
   coincidence, often traceable to a personal event or a chance meeting.
   Being very well acquainted with the people involved, Ben Segal was ideally
   placed to observe the interplay of technical, personal and political
   elements at CERN and elsewhere that helped bring about this major part of
   today's Information Revolution.

   Ben Segal is British, graduated in Physics and Mathematics in 1958 from
   Imperial College London. He's been at CERN since 1971 where he works in
   the Physics Data Processing (PDP) Group of the IT Division.

   NOTE: This talk will be given in auditorium C4, not Estraden. Time: 18:15
   - 20:00.

   This talk is presented in cooperation with NSC's 2nd Workshop on Linux
   Clusters for Super Computing (Oct 25-26), http://www.nsc.liu.se/lcsc/.
