Really. But I couldn't overcome my bad habits. They outnumber me ten to one ;-) > You're right; it isn't. Is that good or bad? What about in an office > environment? Same answer there? Plan 9's aptitude for becoming easily distributed--that is, becoming decentralized--gives rise to a centralized system when it comes to security, because safekeeping of one auth server is much easier than keeping track of numerous authentications/authorization databases spread across the network. It's good. For a _large_ organization, it's good. For the same reasons time-sharing systems were good for university campuses. Centralization lowers overhead--in costs, time, security, and general maintenance hassles. Problem is, sometimes the center and the periphery are the _same_, e.g. in home computing. And for the same reasons a time-sharing system would be bad for home computing, an innately distributed system is also bad for it. Needless to say, home computing doesn't mean casual or insignificant computing. The term only denotes the individual--to contrast with organizational--quality of the computation involved. Decentralization in small scale either overburdens the user with complexity or leaves them at the mercy of a _centralized_ application provider; in safekeeping of credentials, for example. That's Microsoft's dream world of "software as a service." Strangely, Plan 9--if it ever gets to enjoy a large user base--demonstrates the horrors of that dream. > Way, way out of scope.

Then I tried _underscores_ and reserved double quotes for "sarcasm" and "invented/unfamiliar terms." --On Wednesday, August 20, 2008 4:15 PM -0700 Geoffrey Avila wrote: > > Not (currently) a Plan 9 user, but I gotta chime in: > >> It seems the security ascribed to disposable machines comes from that >> "user data" is stored on a different, presumably safer, machine in, for >> example, some sort of data warehouse at a data center.
