The big congratulations this week go to paul, rick, and ravi.
Paul has the class system working that is needed to make Montage
object-oriented; rick tells me it is a lot of fun to use. Rick
himself has linked all of scheran, so now Montage can make all
the interesting Xanadu calls in scheme that we can make in smalltalk and
Meanwhile ravi did performance engineering this week (required
because the system was, aahhh, running so slow we couldn't even
stand it for our own testing, once dean and markm had gotten
done improving everything so much :-) The result is that the
server runs 65% faster than it did a week earlier. This is particularly
amazing because it's running faster even though the permissions
system is now turned on, whereas it hadn't been before--so the
real improvement had to be significantly greater, to compensate
for the extra permissions checking overhead (I should note in
passing that markm and dean, whom I so offhandedly credit for
slowing the system down, probably had something to do with figuring
out what ravi should change to speed the system up :-). (I should
probably also note that we still need a couple of orders
of magnitude speedup before we have something we can call a
product. Performance engineering will be a major effort
once the functionality is in place; on the other hand,
we have a lot of ideas for how to get that
performance increase when the time comes).
Congratulations also go to michael and roger. Michael has snarf
transceivers written, though they aren't quite working yet. Roger
has scrolls bars working in dervish, which is a big step towards
having them work in Tapestry.
This week's moose hunting award goes to markm and dean. They
unearthed a really huge moose that has been hiding under
the rug for a long time: it turns out that it is a LOT more
difficult to figure
out if you can flush data that has been sent to disk than any
of us realized. The good news is that, as regular readers here
will know, this is the first moose hunting award we've given
out this year.
The big welcome this week goes to 2 people: Andy Beals, the newest
member of rick's Montage team (whom I am a week late in welcoming,
I'm afraid), and Mark Le Brun, the new Director of Advanced Projects,
responsible for Montage and Cyberspace and various
other advanced projects.
Meetings: Bill, hill, talk about garbage collector. Markm, dean,
ravi, optimization of canopy. Roger, dean, decrement garbage
collector. Markm, dean, does not propagating unreadable clubs
optimization overlap delayed installation in ent? Ravi, marcs,
discuss next task. Markm, roger, michael, overoading member functions,
send/receive. Ravi, roger, markm, hill, initializers and 2 and
pattern matching. 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.
