Weekly Planning Meeting, 8/21

Highlights 8/21:

The heroic big congratulations this week go to bill, who successfully 
reconstructed our file system after the disastrous crash this 
past week. Congratulations on the successful the recovery also 
go to michael.

Big congratulations also go to mr. hill and ravi. Mr. hill got 
another factor of 3 speedup of the C++ version of the backend 
by using compiler optimization on a carefully selected group 
of source files; eventually, of course, we'll run the optimizer 
on everything, but not till we have something really important 
and worthy of optimization. 

Meanwhile, ravi implemented more of the selection mechanism in 
Tapestry. Now, when you select a link in the link pane, it automatically 
highlights not only the link, but also the material in the text 
pane to which the link is attached. 

With the addition of this feature, ravi has made visible, for 
the first time, a Xanadu capability never before seen in the 
world (uh, except in John Walker's quick-and-dirty frontend for 
the old Xanadu prototype :-) If you attach a link to a block 
of text, then insert new text in the middle, Xanadu links stay 
correctly linked to ONLY the original material. Now that ravi's 
selection highlights the link end, you can see this result: there 
are 2 highlighted areas representing the linkend after the editing 
is all done. 

Folks, nobody, but nobody, else in the world can handle this 

A special congratulations this week goes to naomi, roger's wife, 
for a fine new programmer named Hypatia Elisabeth. Hypatia weighs 
in at 7 pounds, 6 ounces. Imagine--she'll grow up in a world 
that has Xanadu.
A big welcome this week also goes to Rob Jellinghouse, the latest 
member of the Montage team. We're counting on Rob to make more 
immediate contributions than Hypatia :-)
