Thanks O'Reilly
29 Jun 2009
Signing up for OSCON today, I was asked by the O'Reilly site to prove I was human. Of course, it required super-human effort to get it right.
It took me three tries, and all three captchas were as annoying as this one. This is the one I finally got right. That second character? That’s a seven.
Tip: if you have a case-sensitive captcha, don’t include characters that could be mis-interpreted in your image. The letters W U O P S K Z C V all look the same uppercase or lowercase, especially when distorted as captchas are. I could be the number one, a lowercase L, or a capital I. O might be a zero. Even the capital and lowercase J look fairly similar.
