LWN also weighed in (last week) with an article on Smack and the LSM debate. It should exit from subscriber only status soon (but if you are reading this blog, you should subscribe to LWN, it is the best Linux information that money can buy. Plus they seem to really get security and offer a single site that rolls up daily all of the security updates per distro in a single location.).
There was an amusing snafu in the comments section where drag posted a response to the wrong article and got people thinking about an SELinux policy development plugin for Eclipse. One already exists, SLIDE brought to you by the wonderful people at Tresys.
