My problem with SELinux
I think that my core problem with SELinux is that it is very fragile.By this I don't mean that it's buggy and so breaks in normal operation(because as far as I can tell it generally doesn't), but instead thata SELinux configured system is not resilient to changes. If you runthe system exactly as your distribution delivered it, with everythingin the same places and with the same user-ids and so on, the resultgenerally works.

The optimistic view of SELinux's real purpose
In an entry, Zed Shaw recently wrote :
P.S. I have a long bet that SELinux is an NSA backdoor. Any takers?
I'm an optimist, so I think that there's another good explanation forSELinux and all of the effort that the NSA has poured into it. Mytheory goes like this:
Basically, the government has a problem. Historically and forgood reasons , it is theonly customer for really secure systems (ie, rainbow book level paranoid security).This has

WYSIWYG Force Linebreaks - a Module for Input Format/WYSIWYG Zen
A few months ago, I was starting to get fed up with having to manually re-patch the WYSIWYG module on about five of my sites every time it was due for an update, to incorporate functionality that I had hoped would make it into WYSIWYG as a regular button/plugin ( see issue ).
Well, after months of that issue's inactivity, I decided to take the bull by its horns and write up a proper module that would hook into WYSIWYG and allow me to (a) provide the

Articles on Professional Video and Audio Distribution
In the past few months, I've finally had time to post more information about two projects I've worked on in the past year or so at the Cathedral Basilica of Saint Louis—both of them having to do with the sending and receiving of video and audio signals through a very large building.
Click one of the titles to read the article:
XLR over Cat5 - Balanced XLR Mic/Line Audio over Cat5e
In this article, I explain how we sent crystal-clear audio (used
Sending High-Definition Video over Long Distances
I'm working on increasing the quality of video sent through the Cathedral Basilica of St. Louis' in-house video distribution system (right now they use passive composite video connections over Cat5 cabling, and video is very blurry with lots of ghosting), and I thought I'd briefly share my findings in this area.
I've decided to go with an 'active' (powered) video send/receive unit, from Knoll Systems:

Why really high computer security is not interesting to most people
The US government (and to a less public extent other governments) havespent years developing a very robust and theoretically sound model ofcomputer security, complete with rating levels and all sorts of goodthings. They even documented this thoroughly in what is called therainbow series of books .
You might think that a government developed set of computer securitystandards would be widely adopted by industry and broadly used, in thesame way that other government-developed standards generally are. Youwould be wrong; the industry reaction to all of
