I didn't think that blackberry phones were zexy until now:

I've got a mackbook at work, and it's the bomb. I got my split keyboard that lets me type like lightning, my mighty-ish mouse of scrolling doom, and a big ol' monitor that's about the same size as the behemoth iMac that used to rule over my desk. And, whenever I needed to throw down on the go, I could pick that baby up and trot around wherever skills were required.

Until I upgraded to Leopard.

The cpu fan is on nearly non-stop, my battery life has more than halved, and my cute-ass icons now bounce not just once, but several times before hooking me up with my chat. Even getting a terminal to break me into a shell held up for a second. top -o cpu showed me that my problem was syslogd, and I had a growing asl.db file hanging out in /var/log.

Multiple results from search engines led me to this post:

I which I found this solution:

• sudo vi /System/Library/LaunchDaemons/com.apple.syslogd.plist

• sudo launchctl unload /System/Library/LaunchDaemons/com.apple.syslogd.plist
• sudo launchctl load /System/Library/LaunchDaemons/com.apple.syslogd.plist
• sudo launchctl stop com.apple.syslogd

My fan's still on, but I saw an immediate improvement in performance... we'll see what happens.
