First the roll of the eyes: According the this CNET blogger, the RSA registration is vulnerable to SQL Injection! [LINK]

The Smile: This next is a bit self-serving but this latest review of my book [LINK] made me smile:

"The book covers more than the Amazon APIs so I recommend it if you are interested in mashups in general. I’m very keen on JSON right now and was pleased to find that covered as well. I think the author is a very good programmer who has many clever ideas like using XSL to transform XML into JSON (although using Yahoo! Pipes is easier). I’d have to say that this is one of the few programming books I’ve read that presented some really ingenious solutions and creative project ideas. Most books just provide uninspiring "Hello World" examples."

Pretty rewarding to get that kind of feedback.
