I would actually buy them but they are DRM encumbered. I like the Zahn books, but borrowed them from the library when I read them. It just isn't worth paying for something that I can't use in a convenient way and can be taken away from me at the whims of some execs and lawyers.
pfSense is a BSD based router distribution. It has out of the box support for multiple WANs. It can do load balancing when both connections are up and fail over if there is an outage.
I find DIY solutions based on Linux or BSD are more reliable than commercial products unless you spend a lot.
I use pfSense and its QoS tools. I never have problems with my web browsing being affected by my p2p traffic. I have also used smoothwall, which works well also. The downside of these is you have to have a spare computer to install them on, but I have found that the hardware in off the shelf routers isn't powerful enough to properly manage a fast internet connection.
Another trick, make sure you do both up and down stream QoS.
CFL has one problem that people don't realize, the noise the small power supply puts out. I can put an oscilloscope probe within a meter of the bulb and get several volts of noise on the scope, making it not too convenient for lab work.
Also I have gotten reports that my ham radio communications are much less noisy with the CFL light in my room off.
I am all for more efficient lighting but it needs to not interfere with other activities.

It automatically adjusts itself for daylight savings time if you set it to a timezone that follows DST.
Casio makes a watch that sets itself to the atomic clock every day. It cost me less than $50 two years ago
