the latest in spam technology

For some reason comment spam has dropped to near zero on my site. I don’t know whether to be happy or insulted. Meanwhile, on the email spam side of things, it appears that the popularity of Bayesian filtering has sent some spammers over the edge, to the point where they send out messages like this:

This elevates spam filtering into a kind of CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart) [link], you must somehow read the obfuscated message to determine that it is spam.

Algorithm for constructing locked room puzzles

Just thinking out loud here, with no real context.
The player is confronted by a locked door. How does he open it?
A common construction for this puzzle is the paper-under-the-door skeleton key setup: the key is in the opposite side of the lock, and can be pushed out of the lock with a small pointed object, to land on a sheet of paper which can then be pulled back under the door. This is a slightly sophisticated puzzle, because it requires the interaction of three objects: the door, the small pointed object, and the flat object. (The key is not part of the interaction, it is the reward for solving the puzzle.)
Step 1: operate the flat object on the door
Step 2: operate the pointed object on the door
Step 3 (obvious): retrieve the flat object

Hi, guys!

Not something I recommend

If you are happy with life, if you feel like the US is doing a bang-up job in Iraq, if you wish to remain content and unaware of what war is really all about, then I don’t recommend you spend an hour or two browsing through this extensive collection of photos from Iraq at CBS News.
