as well as other details about the course, can now be obtained by anonymous

Subject: Course Notes Available via FTP
This semester I taught our introductory, upper-division numerical
analysis course. It covers nonlinear equations, computer arithmetic,
linear equations, polynomial interpolation, numerical integration, and
numerical differentiation. Since I have taught this and similar
courses many times before, I decided to vary it by writing down my
lectures, pretty much as they occured, *after* I presented them.
Somehow I survived, and the results are available by anonymous ftp at
thales.cs.umd.edu in pub/afternotes. Comments, corrections, and
suggestions will be welcome.

Subject: Network for Continuous Algorithms and Complexity
CAC-NET is to researchers in Continuous Algorithms and Complexity as
NA-NET is to Numerical Analysts. We have a digest that appears
periodically, as well as some of the other features of NA-NET (e.g.,
easy mailing to people who move around a lot). CAC-NET is now in its
second year of operation.
If you are interested in getting more information about CAC-NET, send
a mail message to cac.help@cs.columbia.edu (the body of the message
doesn't matter).
We also make certain materials available via anonymous ftp. At
present we have the following:
cacVV.NN archived issues of the CAC Digest
jftfest.* abstracts from Dagstuhl meeting on continuous algorithms
and complexity (J. F. Traub 60th birthday Festschrift,
September 1992)
numint.* abstracts from Oberwohlfach numerical integration
meeting (November 1992)
The abstracts are available in .tex, .dvi, and .ps form. These may be
retrieved via anonymous ftp from cs.columbia.edu, in the cacnet
directory.

Subject: SIAM Applied Linear Algebra Conference
The 1994 SIAM Applied Linear Algebra Conference
The Fifth SIAM Conference on Applied Linear Algebra, sponsored by
SIAG/LA, will be held in Park City, Utah, from June 15 to June 18,
1994. This conference will continue the major meeting series of
SIAM's Linear Algebra activity group. It will be held at the Snowbird
Resort, which offers inexpensive housing and mountain hiking at this
summer date. The venue we hope will contribute to intellectual
exchange among theoreticians, algorithm developers and users of
Linear Algebra.
The past SIAM Applied Linear Algebra Conferences have been quite
successful intellectually. With this success has come an increase in
attendance and in the number of presentations. Following the 1991
meeting in Minneapolis, many attendees complained that the large
number of parallel sessions kept them from seeing many of the talks
they wanted to attend. The recent 1993 SIAG/SC Supercomputing
Conference, which had a similar format and size, was roundly critiqued
for having parallelism excessive for even a parallel computing
conference.
The organizers of the 1994 Applied Linear Algebra Conference plan to
experiment with a new format that will improve the quality of the
permanent record of the conference and also reduce the number of talks
presented in parallel. The basic idea is to change the way that
contributed papers are presented. We will not hold six-way parallel
sessions of 12-minute talks. Instead every contributed paper will be
presented in any or all of three forms: in a proceedings volume
available at the conference; as a poster display; and as part of a
2-hour "common interest" or "birds of a feather" discussion session
with related papers.
An article describing the new format in detail appears in the current
SIAG/LA newsletter, and is also available by anonymous ftp from the
machine AE.SIAM.ORG (IP number 192.108.225.1) as PUB/LA-NET/FORMAT.PS
(postscript) or FORMAT.TEXT (plain text). We encourage interested
parties to retrieve this article and comment on it (as described
therein).
