I have an iBook 12" G4 800 which should be arriving tomarrow, and I'd like a little bit of advice on various software so I can be prepared. I prefer open source or free programs, but welcome suggestions for commercial software. 1. IRC: What is the best client? I'd need a full featured client supporting DCC transfers, ident, and preferably one that you can script and customize. 2. Usenet: On windows I've used Xnews for all my binary grabbing needs. Is there a similiar proggie for osx? Also, is that a parity program for repairing damaged pieces of posts? 3. Compression: Does OSx have built in support for .zip and .rar formats? If not, what program should I grab? 4. Codecs: I plan on playing Divx, Mpeg-2, Mpeg, Avi, Quicktime, Mp3 and possibly others. Is support built-in for these or should I look for codecs or packs? Thanks again.
