Weekly Planning Meeting, 7/17

Highlights 7/17:

The big congratulations this week go to hill, ravi and rick. 
Mr. hill found and repaired the big garbage collector usage bug 
that had been haunting the system; where it used to require 135MB 
of virtual memory to run the server tests, it now takes 6.5 MB. 
Mr. hill is continuing the hunt, however: he thinks that about 
half of that space is still being wasted. Meanwhile ravi continued 
performance improvements on the server; now the server is running 
between 3 and 4 times as fast as it had been. And rick upgraded 
all the existing Montage code to work with Moose (uh, yeah, there's 
a name conflict here: this Moose is the object oriented extension 
to Scheme that paul has built;this is not a moose we want to 
kill :-)

Congratulations also go to hugh. Hugh has double-click opening 
and closing children.

The moose hunter/killer award goes to everyone who contributed 
to the discussions of object purging, which includes almost everyone 
at Xanadu except the Vice President :-) Last week's moose was 
killed quite dead; unfortunately, it bore children before dying, 
and so the next big moose is to prevent an unbounded depth of 
recursion under worst case conditions while reading/writing to 

The big welcome this week goes to Chris Hibbert, the newest programmer 
on the Xanadu team. Chris's main job will be to build elements 
of Tapestry that will be shared by all three platforms (sun, 
pc, and mac).

Meetings:  Chris, markm, stubble shrinkage. Roland, markm, michael, 
xlint. Bill, hugh, fix quickmail hard disk. Hill, markm, matching 
on underscore. Markm, dean, does not propagating unreadable clubs 
optimization overlap delayed installation in ent? Dean, ravi, 
roger, hugh, fm stuff. Marcs, chip, 4.1 on Victoria. Michael, 
dean, markm, LRU on RAM objects (snarfs, flocks, etc). Markm, 
dean,  discuss booting.
