You won't see me coming....
What are you wearing?Say, this seems to work okay for me ;-)
Thank frig for that. I was sick of refreshing to try and find something that was legible.

Yeah, that CAPTCHA was about as much use as a water-soluble umbrella. You can intrinsically back-door Turing codes by farming them out to a third party to enter. It's a form of man-in-the-middle attack.I wrote a simple piece of C++ code that could break the basic Turing codes used by a lot of sites (such as Samizdata's comment system.) It's harder for more complex systems, but as we've just seen, setting the threshold too high defeats real humans too.
Threshold! It gave me Hebrew script to copy. I've also temporarily disabled it.
"It's harder for more complex systems, but as we've just seen, setting the threshold too high defeats real humans too." It certainly defeated me on a few occasions!" It gave me Hebrew script to copy. " That must have given the anti-semitic loons that infest CiF some new grist for their mills... ;)
Why cant every blog do this, i spend so much time refreshing to get one i can actually read.
