Strange loops:

...[A] story about software security, and the kinds of stunts you can play with software if you're clever and subtle. It's the story of the Unix C compiler, and the virtually invisible back-door security hole inserted into it by Ken Thompson - a story he told in his Turing award lecture.

Outside my area of expertise, but maybe Mark will comment with some actual knowledge. Apple announced ProRes 422 at NAB:

Enter Apple ProRes 422, a new format designed for pristine HD quality, economical hardware configurations, yet high-performance, multistream Final Cut Pro real-time editing - for both high-defi nition (HD) and standard-definition (SD) formats. Apple ProRes 422 features:

- The quality of uncompressed HD at data and storage rates lower than uncompressed SD.

- Performance comparable to or better than the existing HD codecs in Final Cut Pro.

- The ability to work with HD on slower drives, and with more users on shared storage.

Here's Apple's ProRes 422 white paper.
