Giving this seminarIf you want to giveb a talk on W3,
here it is. Anyone may give this
presentation, so long as they give
credit to the authors, Tim Berners-Lee
and Robert Cailliau of CERN. The
idea is we cut down on travelling.
Please mail us if your give the talk
as it would be interesting to know
where the talk has been given.
Your feedback is certainly appreciated
This talk has two parallel "tracks".
The titles of the pages of each track
are cross-linked, so by clicking
on the title you can jump to the
other track. Subtitles in the text
track are also linked to pictures
which are shared by the projection
Practical details for projectionUnless you save the graphics you
want as slides or transparencies,
you will need to give the talk online
with a projection of an internet-connected
computer. If you don't give the
talk on-line, much of its impact
will be lost!
GraphicsAs some of the graphics use many
colours, a projection video system
is better than a tablet for an overhead
projector, as the latter often reduce
the number of colors with weird results.
I suggest using NCSA's Mosaic for
X on a full sized X workstation (sun,
sgi, hp, etc). Make sure you have
ghostview and xv also installed for
the graphics. Good projectors
(Sony, Barco) should handle the scan
rates. Test your equipment well
The current trends are to use are
to use dark blue backgrounds with
white text for readability. You
should configure Mosaic to use colours
which give good contrast. There
are suitable app-default files below
which you can put in /usr/lib/X11/Motif/app-defaults/XMosaic
on your system. Test the fonts.
Use the xlsfonts command to find
out what is available. You may have
to tweak some font sizes if your
system has for example Helvetica
in 37 point rather than 36 point.
Here are some example app-default
The latter was called "big+loud"
and Oscar points out that before
running xmosaic he ran
xrdb -merge big+loud
Alternatively, you an use a NeXT,
with a special project.style file
which you load with the "Style-?Sheet->Load"
button. You will need Preview for
the postscripts (comes with each
NeXT) and some GIFF previewer.
Internet connectivityIf you are giving the talk at a conference
where they plan to have internet
connectivity, make sure the hotel
really knows what this means. Beware
that suns come network handicapped
out of the box: there are complex
rules for getting the nameserver
lookup into the sharable libraries.
Ideally, get someone to set up the
application (pulling it over the
net) to demonstrate that it really
works before you arrive.
AlwaysIf the talk is to be somewhere you
don't know well, take plastic foils
just in case -- the network connectivity
tend to be much better when you have
them with you!
