Spam-filters are trained to catch anything that looks like spam, including discussions of spam and spam-filters.

"Patterns of e-mail use are definitely being impacted both by spam and by antispam filters," said Craig Hughes, chief architect at McAfee Security and co-developer of the open-source SpamAssassin spam-filter project.

"I myself run into the problem all the time, mainly because what I'm corresponding about frequently involves discussions of spam or particular spam strategies..."

"I've lost count of the number of e-mails that get bounced back thanks to spam filters getting triggered by completely innocent words and phrases," said Suresh Ramasubramanian, head of security and antispam operations for managed mail-services firm Outblaze.

How .Mac filters spam

How .Mac filters spam 05/14/2004 01:37 PM
A recent knowledge base entry describes in fairly good detail how spam is filtered from .Mac accounts. According to Apple uses software from Brightmail along with list-based filtering. Apparently Apple also does something on their own:

.Mac also monitors all incoming message activity for trends. This information can reveal a previously unknown source of spam when they begin to send mail to members of the .Mac community.

It's an interesting look behind .Mac. For our .Mac using readers: how good is the spam blocking?

Bloom Filters

Bloom Filters 04/28/2004 12:14 AM

Recent posts about LOAF, which uses Bloom filter, created a small surge of discussion about bloom filters, most notable being the Using Bloom Filters article at Perl.com by Maciej Ceglowski whom I like to remember as the fish guy (visit his blog to see why).

I went fishing for some bloom filter code but couldn't find a general library in either Java or C++.  There was one for Perl but...  Anyhow, it's probably because there isn't much code needed.  Most of the Bloom filter works is finetuning the parameters and choosing the right hashing function so it doesn't really matter.

Beside Maciej's article, I found these pages useful:

• Blo om Filters - the math (obviously explains the math behind BF)
• Some Motley Bloom Tricks (does this and does that with BF)
• Compressed Bloom Filters (PDF - self-explanatory)
• Coding Bloom Filters (game developer's tuturial on BF)

BF is pretty simple stuff but useful in many areas.  I am thinking of using it to detect 'access devices' (user name, password, SSN, credit card numbers, etc.) being submitted translucently (translucent as in Translucent Database) so I can throw up a dialog warning to the user.

Using Bloom Filters

Using Bloom Filters 04/09/2004 04:00 PM
Perl hashes make set membership easy at the cost of memory usage. A lesser-known technique, Bloom filters, trades a tunable false-positive rate for compactness -- and has interesting applications for privacy concerns. Maciej Ceglowski explains the theory and practice of Bloom filters.

DeGan Filters

De Gan Filters. The good Mr. Canter put me in touch with Joel De Gan, who's working on the pDNS (a system modelled... [Raw]

I'll spare my readers the details - but if you're really nerdy, a math kind of gal or guy or in general wanna see the results of great open collaborative work - check it out.  And continue to check out PeoplesDNS.com.

The idea here is that ideas and their implementation turn into money.  Not the other way around.  This is what I wished VCs and investors understood that better.  That it's NOT about money.

Sure making money is important, but the ideas are more important.  The ideas change the world, money buys bombs and war.  Ideas make the world a better place, money just keeps the rich staying richer.  But we software gals and guys like to get paid - so we have to work for money.  But there's always working for ourselves - too.

I just wish soem of those 'rich guys' (i.e. billionaire entreprenuers) would throw a little cash (like a $200M) at some open source projects and see what happens. I bet allot more than the next John Doerr investment.

One day the software industry is gonna wake up and find that we don't need their VCs anymore.  But we will need lots of enterprise salespeople.  That's what VCs will turn into (what they REALLY are right now.)

Have to I told you much I like hanging out with really smart people?

Here's Joel's explanation of the De Gan filter:

Tue Apr 27 9:03:06 CDT 2004
I was introduced to Danny via Marc Canter who I am doing some opensource work with, I am creating a peoplesdns for use with FOAF files for the peepagg project. Danny thought I may make good use of an old form hash filter created in the early 70's called a blo om filter (named after it's late creator Burton Bloom). I realized that this filter was amazing on smaller data sets but needed something to be able to handle huge sets so I created the De Gan filter (following the naming convention) which can hold huge datasets in a one-way hash matrix. It is not efficient with smaller datasets, but with larger datasets it is incrementally more efficient in space than the binary bloom filter.

For instance, DNS can be held in around 75M in a bloom filter, with the De Gan filter it can be held in around 20M With larger datasets this continues (a 250M bloom filter could be held in a 65M De Gan filter and so forth)

Dannys blog entry about the filters

Joel De Gan and Danny Ayers are dudes that I knew would hit it off.  And these Drupal dudes are happening as well.  All that was needed was a little Type-A megalomaniac, visionary thang - that's where I come in.  Everybody's got a role - you line up the right team and magic can happen.

OK - back to testing the world's first true DLA.

Roland Piquepaille writes "Computer scientists from the University of Bath have written a software which transforms your ordinary photographs and movies into cubist works of art and animation reminiscent of Picasso. They trained their software to identify important elements of a face, such as a nose, eye or mouth, until the computer learned how to recognize them on its own. This was achieved by giving the software a kind of 'aesthetic sense.' Then, by "using photographs of a subject taken from multiple points of view, the software automatically picks out important areas within the image, which are cut out as chunks. The chunks are statistically shuffled and a few of them randomly selected and distorted into a 'cubist' composition ready for digital painting." The software is not yet publicly available, but software and animation companies have expressed interest. My blog contains additional references and images."

Internet Filters? Sometimes Good,
Sometimes Bad 07/06/2004 03:14 AM
The NY Times is making fun of both the ACLU and the government for what appears to be contradictory positions on internet filters. They point to two big cases in the past two years, where each side appears to take an opposing viewpoint. In the recent ruling on porn blocking, the ACLU argued that filters were fine and we don't need a law to stop online porn. The government argued the opposite viewpoint, saying filters were not effective by themselves. However, last year, the ACLU argued that filters were a terrible way to stop porn in the case over whether or not libraries could be required to put internet filters in place in order to receive federal funds. However, when you look at the details, the positions aren't as contradictory as the NY Times would like you to believe. The ACLU believes that no one should be forced by the government into using filters. However, if someone (or some organization) decides to use them on their own, that's perfectly reasonable. The government's position is just as internally consistent as well -- looking for any way to stop children from accessing porn. The difference is that the two sides disagree on how effective the means are, and whether or not they block out certain other constitutional rights.

Porn Filters For Adults

Porn Filters For Adults 04/16/2004 03:29 AM
The official target market for internet porn filters tends to be parents who want to make sure their children don't run across porn sites on the web (purposely or by accident). However, according to this Salon article, an increasing number of sales are going to adults who want to keep their spouses from accessing porn. There certainly have been plenty of stories about online porn or "online infidelity" leading to the breakup of marriages, but I do wonder whether or not placing a filter on the computer is just a way of whitewashing over a deeper issue. Obviously, if porn is getting in the way of a relationship, then there are bigger issues than just access to porn.
