    I read a few other anti-spam blogs. There really are some good ones out there so I thought I'd share my top three. Al Iverson's Spam Resource - This is perhaps my favourite blog because the author, Al Iverson, so frequently has interesting information...

    Using my Mac to write posts on this blog

    • 1 Comments
    I was unable to find compatible blogging software for my Mac to post on my MSDN blog (ie, this one).  So, when I'm working on my Mac I have to log in to the site and write the post.  That's not such a big deal, except that Mac software and this MSDN blog...

    How to hack weak passwords

    • 5 Comments
    I was doing my daily stock market research when I happened to come across this article on the strength of passwords and how a hacker would go about trying to steal your password. It's an interesting read. The writer basically goes into a brute-force...

    A trip to Spamatopia, Part 4

    • 1 Comments
    Getting back to my story about my adventure in Spamatopia (it's taking longer to tell the story than it ever did to experience it), I had just left the city of Burstenrise in the district (state? province?) of Pumpenstach. I headed east again to the land...

    The cost of in-house vs hosted services

    • 1 Comments
    I was reading in another blog post about the cost of doing a messaging service in-house vs farming it out to a hosted services company. Basically, for a 250-employee company, the cost of doing it in-house was around $300k, while the hosted-services company...

    Spammers going to sleep?

    • 0 Comments
    I'm taking a timeout from recollecting my memoirs of my trip to Spamatopia to examine the current state of the Spam World. Traffic statistics indicate that the level of spammer volume has subsided substantially in the month of March (and even in February...

    A trip to Spamatopia - Part 3

    • 1 Comments
    As I was saying in my previous post, after my sojourn in Virus Valley during my stopover in Spamatopia, I rented a car and headed east to Spamzahkstan. Along the way, I noticed a lot of abandoned cars on the highway. I couldn't figure it out -- why would...

    A trip to Spamatopia - part 2

    • 1 Comments
    As I said in my last post, I travelled to Spamatopia last week and landed in Michelangelo, the capital city of Virus Valley. Virus Valley didn't seem like too bad a place, but it was very dreary overhead. It seemed like it was always going to rain but...

    A trip to Spamatopia

    • 2 Comments
    In my previous post I mentioned that the spam world is colloquially referred to as Spamatopia (actually, the only one who refers to it that way is me). Well, this past weekend I had the chance to visit Spamatopia so I thought I'd tell the tale of what...

    Bordering on the ridiculous, but it's still kind of fun

    • 0 Comments
    One of the things I do here at work is write a bi-weekly (ahem) newsletter summarizing what is going on in the world of spam. For some reason, I have decided to name the spam world Spamatopia . It is populated with a lot of undesirable types, most of...

    Thursday, March 1 - is anyone out there?

    • 2 Comments
    This past Thursday (March 1, 2007) seems to be a bit of an anomaly. I say this because overall message volume is the lowest it has been since New Year's day. Ignoring that holiday, it's the lowest it has been since early October. Compared to February...

    A reader sent me this link, it's a video of a new Pepsi commercial where they turn the city of San Francisco into a pinball machine. As the subject line says, it's pretty cool.

    Small time anti-spam company to a big time one

    • 0 Comments
    One of the challenges of going from a small anti-spam company (like Frontbridge) to a big one (like Microsoft) is finding ways to automate what we do. We can write spam rules manually, and that works for a while but as soon as we start getting more and...

    Gmail disappointing me... a lot like Walmart

    • 6 Comments
    In the past week or so, I have been getting quite a bit of spam in my Gmail account. It's not image spam, it's stock spam. I blogged a few months ago that Gmail was allowing lots of spam through (no pun intended) but that may have been because an email...

    How long does the average spam outbreak last?

    • 1 Comments
    Ever since July, I have noticed that when spam outbreaks occur, they last for a couple of days and then subside. There is a period of inactivity, and then they go again. My question is this: how long does the average spam run last? To calculate this...

    Anti-spam blogging slowly down as of late

    • 1 Comments
    It has not escaped my notice that my anti-spam blogging has slowed down over the past two weeks, as I alluded to in my other post. It's because I've been involved in a couple of other projects. The first project is collecting metrics on image spam. We...

    Spammers flipping around types of images

    • 0 Comments
    During the past week, I haven't blogged very much.  The reason is that I have been busy doing a whole bunch of other things during the week. Specifically, I've been taking a look at image spam at a higher level.  I haven't worked on any image scanning...

    In my previous post , I defined Two-Point Filtering as the process of using an end-user feedback loop to train a spam filter without verification of the user classifications. I borrowed the Web 2.0 term to refer to the greater community of people contributing...

    Earlier this month I made a New Year's Resolution, that I'm going to learn to use unix a little bit better. Well, so far I've made some good progress as in the past week I have been starting to get used to the sed command. I find it quite handy; how did...

    Sometimes you have to trust my Jedi instincts

    One of the things that annoys me a little bit about the Microsoft revolution is the desire for proof-before-action.  For example, if I want to change a setting to (increase spam filtering | reduce false positives) I have to go back and get historical...

    New type of spam - Blogspot

    • 1 Comments
    This morning I ran across a new type of spam; spammers are creating blogspot accounts and when you go to them they redirect to the real payload site (in my case, pharmaspam). Google ought to be able to help out with this. They own Blogspot, so I would...
