Motorola Math Library for Power Macs -- Mark Granger has compiled a shared library for Power Macs running System 7.5 or later that accelerates Mac OS math functions. The library is built using the math library from the Motorola C/C++ Software Development Kit, and users claim it can provide as much as a 25 percent speed increase on floating point math operations, which could greatly benefit some applications. If you don't use your Power Mac to do heavy calculations, this library probably won't help you, but if you live for transcendental functions, it's worth a look. [GD]
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.
