It was actually possible to produce 1Gp images 27 years ago. The
Viking Mars Lander (`76) had a camera that consisted of 3 photodiodes, and a nodding mirror that would rotate around a vertical axis to sweep a line of image past the diodes to get a panoramic view. At absolute highest resolution, you could get about a billion pixels, but it took over an hour and was never used on Mars because of bandwidth limitations. We used this to take group pictures of the team in which you could get up and move to another part of the circle after the mirror had passed by, so some people showed up five or six times. We figured the life forms on Mars, being quick studies, had figured out how to evade the mirror.

My "spam receipt rate" has dropped to almost zero. Could this be a result
of the arrests in Virginia? Have others experienced this? Frank |

I can say my own SPAM level has dropped to about zero also.
I was hoping the reason I stopped receiving so many offers for anatomical enhancement was an enhanced reputation! I guess your Virgina story is a more likely cause, alas. -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Frank Wimberly Sent: Saturday, December 13, 2003 10:27 AM To: The Friday Morning Complexity Coffee Group Subject: [FRIAM] Spam My "spam receipt rate" has dropped to almost zero.

I'm still hovering at about 600 spam messages per day, perhaps because
I'm a contact on numerous domains. I wonder if Earthlink has installed some new spam filtering and that might account for your decrease. On a somewhat tangential subject, spam filtering is starting to cause me concern. While it's good not to be receiving so much junk, the process of spam filtering has the potential of turning into censorship, especially as these filtering processes become more and more centralized. Here's a case in point. I maintain a Web/email-based group in which we do periodic electronic polls. Most members are in the medium to low range in terms of computer skills. When started our first poll, I was surprised at the low turnout. Then I starting some emails complaining that people had not received their "vote ticket". The vote ticket is sent automatically from my server, but I found that many people did not receive theirs. After investigation, I found that in most instances the email had been filtered without the knowledge of the recipient. In fact, most people I've worked with on this issue did not even realize there was a spam filter in place. I walked one guy through the process of getting to his blocked email only to hear "Oh, there's that email I was waiting for" in regard to email sent to him from a friend. He had thought the friend was mad at him and not replying. The thing that really bothers me is the centralization of these spam filtering services. Here, local providers such as cybermesa.com and newmexico.com use a service called "postini" in California. All mail sent to customers of cybermesa.com and newmexico.com goes to postini, and then only the unquarantined mail is sent to the servers at those providers. (Check out the MX records for these providers.) The big providers like AOL, MSN and Earthlink have their own in-house filters. An ex-colleague of mine at AOL recently showed me their "caught spam" counter available to this internal account. It was up to about a billion for that day! In the case of my vote emails, they were categorized as "special offers" by postini. And there is essentially no way for a small fry like me to contact postini and do anything about it. All I can do is to encourage people behind the postini shadow to add me to their "approved senders" list. But with my user base, that's somewhat akin to asking them to go out and tweak their car's carburetor.... What really worries me is the diminishing number of "switches" that can be turned to the off position for certain senders, without notice or recourse, and with no interaction from the affected customers or even their ISPs. The old adage that "the Internet treats censorship like damage and routes around it" is becoming less and less true because their are fewer routes. A few months ago I read an article by John Walker called "The Digital Imprimatur" (http://www.fourmilab.ch/documents/digital-imprimatur/) in which he warned about these sorts of things. Serendipitously, I have since witnessed first hand the emergence of one of the processes of which he warned. We need to be vigilant about being done to the infrastructure of the Internet. -Ed Puckett. On Dec 13, 2003, at 8:26 AM, Frank Wimberly wrote: > My "spam receipt rate" has dropped to almost zero.

My incoming mail server has no filters and it's generating junk at its
usual rates, on track for better than 100 a day. It's actually been a bad week, some Russian joe jobbed me (ie sent spam listing my email in the From header) so I got a few hundred "mail could not be delivered" messages in Cyrillic on top of the usual crap. -- rec -- Frank Wimberly wrote: >My "spam receipt rate" has dropped to almost zero.

Hmm. I actually have accounts with two providers (Earthlink and MSN--Don't
ask.) My academic email addresses forward to the Earthlink account. I would say that more than 90% of the spam I receive arrives via MSN. There are various people that I have written to without receiving a reply, which is very surprising in view of who they are--lifelong friends (who may have "passed" come to think of it.) Now you've got me worried that anti-spam filters are the reason. But that would be better than the alternative. Frank ----- Original Message ----- From: "Edward A.

Like Ed, I typically receive 600-800 spams daily, virtually all of which are caught by
Cybermesa's Postini. I have had a number of email addresses consistently for more than a decade, and that has something to do with it. After the Postini filtering, I receive about 50 emails daily, of which perhaps 10 are spam. When Cybermesa first installed the Postini system a few years ago, it took a couple of weeks of daily checking to be asssured that I wasn't missing mail I wanted, and since then it has worked quite well. I do periodic spot checks on the Postini folders containing the spam before I delete them, and I don't seem to have missed anything. It's a good system over which you have fairly good control, but does not solve Ed's problem with increasing numbers of users with little or no experience in doing much of ANYthing manually with a computer. -----Original Message----- From: [hidden email] [mailto:[hidden email]]On Behalf Of Edward A.
