There’s quite a bit of additional discussion on my Windows Vista post on this programming reddit thread. A sampling of opinions:

• there are virtues to this feature (i can appreciate this): some would temper it with a warning or other notification (given how regularly Vista nags me about innocuous things like creating folders, it’s puzzling that creating a virtual file doesn’t merit a peep)
• it’s bizarre to want to edit things in Program Files (in a perfect world, perhaps, but the reality is, developers sometimes need to change things)
• Scott Hanselman has a post on the virtualization feature with a lot less whining and a lot more technical detail that you may find helpful

One commenter pointed out that McAfee’s SiteAdvisor, which is supposed to warn you about bad sites, thinks SemanticBible is one of them! The basis for that assessment is a link i have somewhere to daml.org, a repository of OWL ontologies and data, which was originally set up as part of the government funded DAML research program by my former employer, BBN Technologies (DAML is the one of the progenitors of OWL, the semantic web language). SiteAdvisor’s claim is that daml.org was “found to be a distributor of downloads some people consider adware, spyware or other unwanted programs.” If you go to their assessment of daml.org, that’s based on a couple of downloadable zip files that are apparently infected with viruses. Given that the DAML site exists to share resources, i guess some of this is inevitable. Not that this excuses the problem: I remember pointing this out to one of the daml.org guys in the past, but apparently they haven’t fixed the problem (and SiteAdvisor doesn’t make it too easy). Anyway, i’m in the process of trying to get my black mark with McAfee removed, but let me assure you that SemanticBible does not knowingly distribute or encourage the distribution of malware.
