Weekly Planning Meeting, 2/27

[Marc Stiegler <marcs>]

Highlights 2/27:

The big congratulations this week go to ravi and roland. Roland 
installed the crutch, the preprocessor which repairs C++ compilers 
so that they handle complex && and || expressions correctly.

Meanwhile Ravi made history with his presentation of the Waldos 
layer of software: it was the shortest major discussion in the 
history of Xanadu. And everyone seemed to like it, as well! Magnificently 
done, ravi.

Congratulations also go to rick, whose presentation on Montage 
also survived the brutal inspection of the Xanadu team.

And congratulations to hill and roger, who got some of fm all 
the way from smalltalk through the translator through the C++ 
compiler. 

Finally, congratulations go to bobp, whose System Overview is 
now ready for shipment (though there are still missing sections, 
at least it can give people a good taste of what's coming). 

For those who are losing track of the terminology, here's a brief 
update:

The Waldos layer is the new layer of the backend between Doc&Links 
and Orgls&Berts. Waldos is the deepest layer developers need 
ever look at, according to our current best projections.

Montage is the company sensitive project rick is working on: 
an authoring system to lie on top of Xanadu, to make it easy 
for nonprogrammers to create Xanadu applications.

Tapestry is the new internal name for the frontend we have heretofore 
referred to as the Infofactory. The reason Montage and Tapestry 
are internal names is that we may have trouble trademarking them. 
But at least they roll off the tongue in more liquid tones than 
Infofactory and Squat ("Squat" was the previous name for rick's 
project :-). 
 
Meetings: Markm, ravi, dean, discuss substamps. Dean, hugh, discuss 
regions and text. Michael, bill, who does what on letter bombs. 
Markm, find Z-stip paper for rick. Bobp, joel, review info packet. 
Dean, hugh, discuss compositors hanging on to wrong attributes. 
Ravi, dean, rick, markm, unify view builder and waldo maker. 
markm, marcs, discuss perfect scheme translators. Hill, Roland, 
michael, discuss crutch.Roger, michael, dean, types to compile 
the ent. Bobp, joel, marcs, discuss Apple and smalltalk. Marcs, 
dean, joel, parc place strategy. Dean, michael, structured debug 
on the ent. Michael, dean, break up the ent for the disk on Wednesday. 
Michael, dean, markm, ravi, efficiency of internsets. Roger,, 
hugh, dean, ravi discuss system independent attributes for the 
frontends  after fm does paragraphs.
