Researchers find that dogs can laugh and it calms other dogs. I'm not sure if this qualifies a genuine breakthrough but its interesting none the less. Dogs can show aggression, fear, and other emotional responses so pleasure and "laughing" shouldn't be out of reach. 

They say the long, loud pant is the sound of a dog laughing, and it has a direct impact on the behavior of other dogs.

It's more noteworthy that researchers (where do they get these funds by the way?) have indentified the laugh as a a long, loud pant. This confirms the suspicions of 70s Hanna Barbera Cartoonists (Muttley's laugh: listen here).

I know I'm a bit late to the game, but some of you may not know that Mozilla Firefox 1.5, was released last week. If you are still using Internet Explorer on your Windows machine, you should install and start using Firefox because its more secure, faster, and extendable. This Introduction to Firefox is a great starter's guide for making the switch form IE.

If your a web developer or designer, you should be interested in what's new in the browser. Simon Willison has an overview of new CSS tags, and other feature, that Firefox supports.

Since I configured my mail server, I was getting the following lines in my auth.log. Everything was working, users had to log in to receive or send mail, so the messages were really cluttering the logfile.

I wasn't using auxprop as the method to check passwords, I am using saslauth. But googling around to find a way to get rid of them did not find a solution. On a hunch, I uninstalled the libsasl2-modules-sql package for my Debian version, and the lines have stopped showing up in the authentication logfile. Everything is still working, so that package wasn't needed by my setup.
