v.what? -- A typo bit us in last week's issue. The article on the PSI PowerModem incorrectly said that the modem uses v.32 error correction and v.32bis compression - those numbers should be v.42 error correction and v.42bis compression. Sorry for the confusion - the modem supports the v.32 and v.32bis communication protocols, which define the connection speed (9,600 bps or 14,400 bps), but are different from the error correction and compression protocols.
Mac OS X Zip Expanding Utility
Firefox (and possibly other applications) may ask you what you want to do with .zip archives that you download from the Internet. If you want to expand them with Mac OS X (rather than StuffIt Expander), you may be unsure of which application actually does the job. You're looking for Archive Utility (in Leopard and later) or BOMArchiveHelper (in Tiger). In either case, the application is stored in Hard Drive/System/Library/Core Services/. Don't move it from there, though, or you'll confuse matters.
