Compare this comment to Big Jeff's earlier work:

How many of these vulnerabilities were due to Firefox itself, and how many due to plugins? Does it matter? If FF allows the plugins enough control over the browser to present a vulnerability in the browser, then that's a vulnerability in FF that they need to fix. Saying "oh no, we don't have vulnerabilities ourselves, we just allow vulnerable plugins to run" doesn't speak much to the security of Fire Fox. In other words, the cop-out doesn't fly. If FireFox is vulnerable to something another browser is not, i t has one more vulnerability than that browser, period.

Big Jeff, you appear to put a lot of time in on Slashdot. Do you do it for a living?

This comes down to how long it is. A cosmic string isn't the same thing as a string in string theory. A cosmic string is very long macro scale topological feature of the universe while a string theory string is a model for subatomic particles. However you can investigate cosmic strings in string theory leading to the theory of stringy cosmic strings of Vafa et al..

The BBC does not hold all rights over all of its programmes, actors get repeat fees and so on, the BBC is forced to buy a large percentage of its programmes from independent producers who will retain some rights. Often the BBC will only have UK rights. For example the iPlayer makes "Heroes" available. That isn't going to happen without robust DRM. In order to make the relatively free distribution of content acceptable to rights owners they needed either DRM or a complete rethink of their commercial practices. Its new supervisors are not really up for that kind of thing and want an iPlayer type solution quickly. It claims there was no acceptable DRM alternative and will have other (Mac at least) solutions available soon.

Macs are also excluded.

Still the BBC is noticeably less ambitious than it was and Ashley Highfield does not appear to look much further if there is a Microsoft solution available.
