Excerpt: Most deployed versions of Apache are potentially exploitable, as mod_rewrite has been found to be vulnerable to a stack smashing attack.  It is somewhat muted by the fact that only certain rules cause the problem.  The vulnerability is caused by an off-by-one error — the most common programming error known to man.  Many SEOs use mod_rewrite, but not all will be affected; I checked my rules, and I am not exploitable (otherwise I wouldn't post this), but I'm …

Excerpt: A major copywriting concern becomes manifest when one realizes that many popular queries happen to be English, but they are just plain awkward constructions.For example, when a user is looking for a "Vioxx attorney," one must consider whether this phrase is actually English. The answer is yes — and no. Ask yourself a simple question:"Would I actually call up a law firm and say: 'Hello, do you have a Vioxx attorney?'"Maybe.  But I'd be more likely to phrase t…

Excerpt: Link Bait is the hottest new fad in link building, and I keep my eyes open for obvious examples.  If it weren't on CNN, I wouldn't even believe it.  This is one of the funniest articles I have read in awhile:"Study: More Americans too fat for X-rays, scans" http://www.cnn.com/2006/HEALTH/07/26/obesity.xrays.reut/index.html (there, I linked to it) Basically, the article states that as a result of eating too many double cheeseburgers, Americans are either not fitti…
