  • To make it easier to jump to a specific presentation, I have created a timetable. It was missing from the original web site. Enjoy these highly interesting talks.

    Oliver Schmelzle, in Webcast Timetable for Spam Conference Sessions [], provided the following timetable for the webcasts found at []:

    Session 1

    0:00:30, Teodor Zlatanov, spam.el Maintainer, "Gnus vs. Spam"
    0:10:00, Bill Yerazunis, MERL, "Sparse Binary Polynomial Hash Message Filtering and The CRM114 Discriminator"

A couple of corrections have come up, and I don't want the eventual archived versions of this not to reflect those contributions (hello, future Google spelunkers!), so here's a general cross-linked addendum:


  • Spam is an abuse of a public-writable area of your attention. It appears visually as billboards, unwanted email, and junk snail mail; audially as phone salespeople; and in full video as TV adverts.

    Individualist solutions such as spam filtering, whether email spam or visual spam [], obviously have limits. It puts the onus on each and every person to do the filtering, and doesn't prevent all the effort that went into creating and distributing the spam. As the people at the conference observed, all these sma
