Skype and Leopard firewall

Leopard's firewall breaks Skype because it modifies application bits when a program is added to the firewall. As first mentioned on Accelerate Your Mac, applications that run a self-integrity check (as I believe Skype does) will fail to function properly after Leopard modifies the program. The solution? Disable Leopard's firewall.

Hard drive benchmarks

I recently picked up a FreeAgent Pro (320 GB, SATA/USB 2.0/FireWire 400) to use as a backup drive for Time Machine. Before my purchase, I had called Seagate and asked what chipset was found in the enclosure - the agent told me it was an Oxford 924DSb. This is strange as the 924 chip supports FireWire 800, too. Nevertheless, I ran some quick benchmarks. Duplicating a 701 MB file on my internal hard drive (120 GB/5400 rpm) took 43 seconds, while duplicating a file on the FreeAgent Pro took 42 seconds over FW400.
