Who else out there in NZ is running BSD386 0.1? (the free one)

Its been up and going on aklobs now for a while and seems to be quite stable

I have it on a 486DX2-50 EISA bus system with 8megs of ram, 256k cache,
scsi controller (1542b) with NEC 660meg drive, Archive 150/250 meg tape,
vga etc..
The NFS is very nice. It talks to ESIX NFS on a 386-40 system running 
ESIX SVR3.2, absolutely no problems here.

Is anyone else working on any extensions to BSD386?
I'm interested in finding out if that 'working group' suggested by
someone at VUW ever got into doing any 'work'. If so who is involved
and what projects are being looked at?

Also I'm interested in Netfax for BSD. The code I obtained is pretty
awful stuff so I'm now looking at a complete rewrite for BSD386 (and
ZyXel 1496E and/or Zoom v32bis modem).

A Place for Jazz is a non-profit organization that promotes Jazz in
the Capital District.  Every fall A Place for Jazz sponsors a series
of Jazz concerts in the "whisperdome" of the First Unitarian Society,
1221 Wendell Ave, Schenectady.  Their first concert of the 1992 season
features jazz vocalist Ronnie Wells, this Friday, 18 September,
starting at 8 pm.  Tickets are $13.50.  For information call (518)
374-6912.  Tickets are sold at the door, unless they run out.

Quoting from their newsletter:

"In recent years such stars as Shirley Horne, Roberta Flack, and Buck
Hill have emerged from Washington, D.C. and received national
attention.  Now Ronnie Wells reputation has burst out of the Beltway.
Her performance is a continuation of the long tradition of the long
tradition of Jazz songwomanship that has passed from Bessie to Billie,
Billie to Sarah with a touch of Ella, Dinah, and Carmen along the way.
You'll love this opening concert.  You'll love her quintet under the
direction of Ron Elliston.  We sincerely hope you manage to get a
ticket because we would not want any of our friends of Jazz to miss
this one!"

Does anyone know if Ziebart's local franchise has changed hands?  They
were noticeably more incompetent, and ruder, today at my annual
checkup.  They sprayed muddy water through the door seals into the
car, and were reluctant to wipe it up.  The manager said that that was
normal.  The manager also refused to touch up rust spreading from one
of their holes until I asked for the name of his boss.

I would not get rustproofing on a car now, but figure it's probably
worth it to keep paying $30/year to maintain the warranty on my 7 year
old 100,000 mile Civic in case it should start rusting while Ziebart
is still in business.

Don't forget channel 8 which used to be the local government channel.  That
makes three unused.  Another channel that has been requested is BET (Black
Entertainment Television [I think that is what BET stands for]).  With Troy
Newchannel's smaller selection than Capital Cablevision and the fact that
certain areas such as RPI's dorms are now carrying Capital Cablevision, I 
would think that Troy Newchannels would want to listen to its subscribers.
Definitely keep me posted...

Or better yet (for me, anyway), can Albany residents get Troy

I'm curious.  I thought Newchannels had an exclusive franchise in Troy.  If
so, how are the RPI dorms able to carry Capital Cablevision?  Does this mean
Troy residents can request service from Capital Cablevision?

I am not sure about an exclusive franchise.  The dorms have a non-cable feed
from Capital Cablevision.  In other words, there is a funny looking atenna
on each dorm that receives the "cable".  I guess Troy Newchannels has franchise
on cable wires running on telephone poles?  I am not sure if a Troy resident
could get cable set up like this at their house.

The cable provided in the Quad room comes from 'Capital Wireless' which is not
affiliated with either Troy Newchannels or Albany's Capital Cablevision. A 
friend of mine who lived in Stackwyck (or near there) last year had to request
a conventional hookup from Troy Newchannels. I don't know where the dorm lounge
cable comes from.

Could the dorms legally get their own satellite dish, pay the fees and
effectively set up a provate service?

ROBUST GEOMETRIC OPERATIONS  WITH  INCIDENCE  
AND  LOCATION  CONSTRAINTS*

Engineering  applications of Computational Geometry re-
quire robust and stable algorithms that do not  introduce  catas-
trophic  distortions  due to finite-precision limitations of com-
puter representations.  We present a new family of  approximation
methods   based  on  continued-fraction  expansions  of  rational
numbers. These approximations generate  integer  coordinates  and
maintain  the  coincidence of points and the collinearity of line
segments under geometric transformations and  Boolean  operations
(where  normal  round-off  could produce inconsistent results). A
related set of approximations guarantees  that  approximated  po-
lyhedra  completely  enclose  (or  are completely enclosed by) the
original polyhedra. The methods are computationally practical  and
have tight bounds on the maximum error.
