Subject: NA-Digest Subscribers Spammed

Last weekend, many NA-Digest subscribers were "spammed" -- that is,
unsolicited and inappropriate advertisements were sent to their
electronic mail addresses.

Two different messages were sent. The first one was an advertisement
for a web page which "may cause you to lose 10-15 lbs". The second
was made to look like a reply to the first one from an na-digest
subscriber, but it actually came from the same source as the first
one, and contained several additional advertisements. Both messages
originated from host

I noticed the spamming while it was in progress, and removed the
offending messages from the mail queue before they could be delivered
to everyone. According to the logs, 4029 total messages were sent.

As a result, the following actions have been taken:

1. NA-NET's "sendlist" command (which allowed anyone to obtain a list
of every na-digest subscriber) has been disabled.

Disabling sendlist will not prevent future abuse by these people, but
it might prevent future abuse by others.

2. The NA-NET server machine, has had a "black hole" route installed
to prevent its exchanging any network traffic with This
is a short-term measure which was taken because the spammers were
sending multiple messages.

3. A complaint has been sent to's Internet Service Provider.

Subject: Integration Question Solved, Thanks!

The response to my question (NA Digest 9/15/96) has been very generous. The
result is

Integrate[( ((1-x)*(1-y))^(-1/2) ) / (x+y), {x,0,1}, {y,0,1}]
= 3.663862376708876060
= 4*Catalan

and that has been found by a few researchers. Many thanks to all who
contributed. You are Frank Jones, Sue Minkoff, Colin Rose, Frank Stenger,
Valentin I. Vangelov, Garry J. Tee, Pierre Verlinden, Walter Gautschi,
Chris Nex, Victor Adamchik, Norm Fuchs, Knut Petras, Thomas Dehn,
Greg Gaspari, Ron Keam, Jin Ma, Wei-Chi Yang, Peter Kaps, Norbert Ortner,
Prof. Wagner, and Alan Cohen.

The question was a special case of a more general integral. Victor Adamchik
of Wolfram Research also solved the more general problem. When I have written
the resulting research note, I will put it on the web and notify the people
on this list.

Subject: Workshop on Iterative Methods in Czech Republic

Dear colleague:

We are writing to you to announce an
International Workshop on Iterative Methods and Parallel Computing,
to be held in the Czech Republic. We hope you will be able to
participate. The tentative dates are June 16-21, 1997, to be confirmed
in the next couple of months, once all funding has been secured.

The Workshop will take place at the hotel
Devet Skal in Milovy (literally "Nine Rocks").
Milovy is a small village located in the Bohemian-Moravian
Highlands (Central part of the Czech Republic) at about
100 kilometers (65 miles) from Prague.
We are planning to charter buses to take the participants from
Prague to Milovy and back.
There is also a regular scheduled bus from Brno to the Hotel. Brno is
on the Southeastern corner of the Czech Republic not too far from Vienna.

The cost will be around $250-300 (U.S. dollars) for the whole week,
including accomodation, meals, conference fee and the bus from and to Prague.

We expect about 100-150 participants, so the emphasis will
be on a "workshop", i.e., on work among the pariticipants,
with periods of free time for unstructured discussions
(as well as swimming, hiking, etc.)

So, please mark your calendar, and let us know if you are interested
in participating by sending a message to IMPC97@UIVT.CAS.CZ .
Dates for abstract submissions will be sent once the Workshop date
is definite.

Please feel free to resend this message to your immediate collaborators and
students, if you think they would be interested in participating in the

We hope to see you in Milovy.
