Sun does lousy hardware when they put Sparcs in PCs (ultra5, > ultra10, blade100). But their servers generally are nice with large memory > busses and very scalable SMP architectures. > Considering that Con's general mass target for his -ck patchset is single-cored x86/PC-compatable system such as a Celeron or a single-core Athlon with 32-256 MB RAM, (disclaimer: this is an assumption) I think he is being rather sarcastic. The only other way to interpret this is that those machines are totally different from what Con uses for development, and as such, maybe Con'd find them "lousy" because if something DID go wrong, it would be less obvious he'd figure it out right away. But I think it's a joke, guys. >.> -- ~Mike - Just the crazy copy cat.
