That Point

There is an extreme to anger, a position I would deem “anger nirvana,” at which your unfavorable expectations are so precisely met by someone that it becomes more hilarious than the funniest of positive situations.

Work is completely awesome.  I don’t miss school at all.

That’s serious.  That may not sound serious in light of the above, but it is.  It’s great to be a Real Person.

Wuf

Ajax just bricked my work computer’s browser.  I need a new computer.

More Lunch Break

I’m almost ashamed that Office 2007 seems so visually appealing and functional to me.  Most of this is likely given to the fact that I’m a Keyboard Nazi and not prone to the level of menu browsing endemic to typical Office users using typical versions of Office.  It’s quite a change to use, especially if you are comfortable with the various rat mazes required to do things in the old style of Office.

Anyway, Vista freezes or randomly reboots my machine when I try to put it into sleep.  If you ask Google about “vista sleep” some ire of various intensity will surely appear.  My Athlon X2 machine has never exactly been a champ with regard to suspend/hibernation, but I think this one is pretty much Vista’s fault, now that I’ve removed the dual TV tuner card.

Lunch Break

Looking at Cluster 2.0 on IE 6 does show some serious fowling.  Should I dismantle the UI and fix it, or just suggest Firefox 2/IE 7 as the “preferred” viewer?  I’m leaning toward the latter, as I’m hoping IE 6 is almost gone at this point.  It really drives me nuts.

Cluster Is Up!

I’m excited and very challenged right now to come up with a good next post…

Cheeseball

Among corny shows, Step By Step was remarkably real.  After watching a Full House and Family Matters, I am struck by the distance that show traveled from the others.  Of course, Cody’s face still needs a nice, firm shovel print most of the time, but it serves as a suitable laugh in small doses.

Also: why does “traveled” not have two L’s?  I am always in disbelief when that one gets the red dotted line underneath.

All Back and Moved In

It’s great to be married!  It’s kind of hard to re-start a blog with a typical post after a complete change in circumstances, but the show must go on.

Despite my continuous “file cabinet accessories” (yes, I didn’t know they existed until recently either) problems, server stuff is going well.  Right now the battle regards spam filtration, which is a tough little nut to crack in many cases.

SpamAssassin (SA) is not as good as I thought it was… especially when you’re running the setup I am (which is essentially a command-line mail client being run every five minutes and personally forwarding mail to an aggregated local mailbox).  I believe this is because spam filters like to look at where spam is coming from.  Since it all comes from my machine (most recently), SA tends to think the best of things.

So, like everyone else who is not greylisting (somewhat evil) or collaboratively filtering (fairly ineffective in my experience) I went Bayesian.  I trained with Kristin’s and my few thousand of archived legitimate mails, augmenting that dataset with a publicly-available recent spam repository of a few more thousand.

It was a total disaster.

The most obvious pharmacy mails were getting passed with a very big thumbs-up from the filter.  So, I dumped the wordlist and trained with about 10-20 mails in Kristin’s inbox and only the spam that has arrived since.  Difficult spam is getting a 0.5000 score (probably best expressed as “perfectly unsure”), and somewhat repetitive stuff (even with some random noise added by the bots) is already getting pared out.  I would stress that this is a very small training dataset, and accuracy is slightly impressive at this point.

I wrote a custom shell script that, when invoked for a certain user name, will empty the user’s “Junk” folder into the trash can after training the spam filter.  This could be run on a scheduled basis, but for now I prefer to invoke it by hand.

I’m very pleased with all of this.  More updates to follow as the dataset increases.

Mute Math

This band seems interesting.  Could they have done the theme for Transformers?

Oh, Man

I’m not supposed to find this funny.
