St. Clair Software has updated their CPU-saving utility App Tamer 1.3 with more control over when the AutoStop feature gets activated. With this update, you can set AutoStop to begin working its magic only when your laptop battery falls below a specified charge level, which will help minimize battery drain and speed up recharging. The release also includes several AppleScript commands that enable you to turn AutoStop on and off as well as wake a stopped application in your scripts. Additionally, this version fixes a problem that caused Web browser helper applications to freeze the browser and an issue where disabling AutoStop didn’t actually disable the feature for some machines.

Syslogd Overwhelming Your Computer?
If your Leopard (Mac OS X 10.5) system is unexpectedly sluggish, logging might be the culprit. Run Activity Monitor (Applications/Utilities/ folder), and click the CPU column twice to get it to show most to least activity. If syslogd is at the top of the list, there's a fix. Syslogd tracks informational messages produced by software and writes them to the asl.db, a file in your Unix /var/log/ directory. It's a known problem that syslogd can run amok. There's a fix: deleting the asl.db file.
Launch Terminal (from the same Utilities folder), and enter these commands exactly as written, entering your administrative password when prompted:
sudo launchctl stop com.apple.syslogd
sudo rm /var/log/asl.db
sudo launchctl start com.apple.syslogd
Your system should settle down to normal. For more information, follow the link.
