  Storm Season!
Here in the south, summer brings with it the almost daily threat of sudden thunderstorms. Best Buy, Circuit City, and the Asian electronics manufacturers make millions of dollars a year off equipment that is damaged or destroyed by outside electrical surges.

You should ensure that all your valuable electronics are protected by surge protectors when they are connected to outside wiring. Of course, you won't forget your entertainment system, but remember that a surge can enter one device and travel through any wire connecting it to others. This means you should protect printers, telephones, and networking devices - including the cable or phone connection that brings the internet - even if those devices themselves are not valuable.

Purchase good quality multi-mode surge protectors. A starting rule of thumb is that if it costs less than $20, you should save it for the kids' TV or other isolated low-value equipment. I prefer to use battery backups as my surge protector. Along with excellent surge protection, they'll save you from losing your current letter or having to reprogram the TV if the power is out for up to a few minutes. In addition, they protect against low or high voltage conditions (such as running a vacuum cleaner) that technically don't constitute a surge. The downside is that most UPSs will beep as long as the power is out unless you have connected them to a computer and used their management software to turn it off.

Most single-mode surge protectors will protect you once. That means, if it's saved your bacon once, it won't do so the next storm. It will still function as a plug strip and your equipment is still powered, just not protected. If it has an indicator that it's bad, believe it!

Of course, the best surge protector is 10 inches of dry air - that is, pull the plug in extreme storms.

I've worked in Windows support over 10 years and many people come to me with all sorts of random questions. When I complete a particularly comprehensive correspondence on a particularly common issue, I'll post it here. There are hundreds of other blogs and sites that do the same thing, but another opinion doesn't hurt. Many of my offerings may contain content from others. If I used primarily one resource, I try to reference it. If you think I've misappropriated your work, please let me know.

Most of the examples shown here can be downloaded from http://3500calories.info/links_blogger/. "Numbers for Everyone" is not about math; it's barely about arithmetic. It's merely an attempt to promote a literacy about numbers. We should apply a healthy skepticism to everything we read, but many people think they aren't good at math, so they take any statement with numbers totally at face value. This allows, even enables, a lot of fallacious (bogus) "knowledge" to be disseminated without challenge.
