Comments are back…with a twist

Published by at 9:20 am under Uncategorized

I got tired of the blog spam from the on-line gambling sites and the Cingular ringtones folks and have installed the Boriel’s wonderful capcha plugin for WordPress (yes, that’s how he spells it…in actuality it’s written as CAPTCHA).
What is CAPTCHA? Captcha is the acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart.” You can find more information about it here.
Now, if you want to submit a comment on my blog entries you will have to pass a reverse turing test. It’s simple…just put in the numbers shown in the graphic below your comment and press submit. If the numbers entered match the numbers in the graphic then the comment is accepted. The graphic is not machine readable so blog spam bots cannot parse it to get the numbers.
Now, I had one problem with getting the capcha plugin to work — the graphic wouldn’t show up. It turned out that I needed to recompile my libjpeg library as well as the gd library and PHP in order to fix the problem. Now it works great.

    Thx for using Captcha! You finally did it! 🙂

    I have new ideas about autodetection to avoid such setup problems.

    On the other hand, your captcha is somewhat hard!! 😕
    I solved it using more readable fonts, to stop people complaining.
