After my new website was online, it took spammers only 4 days to find it and flood it with comment spam.

So I decided to implement a captcha. But, to turn anti-spam measures into something useful, I decided to try out reCAPTCHA. This project helps archive.org with their effort to scan books. OCR is not 100% accurate, and reCAPTCHA helps to decode the words that the computer can't decode, but humans can probably read.

What the captcha basically does is present you 2 words: one that it knows how to decode, and one that it was unable to read. If you got one word right, it's going to assume that you also know how to read the other, and will use your interpretation for the book scan. To prevent abuse and improve quality, it can send the same word to multiple people.

I haven't used it much myself, and encountered it only on a few sites. If you are having trouble with commenting on my site because of this captcha, let me know. (How can you let me know if you can't comment? You probably know my e-mail address and if you don't, you can easily guess. :-))

If you like the way it works and want to support the project, add it to your own site. If you use WordPress as I do, it's very easy to setup: you can download a WordPress plugin here.

I used to host my blog on achievo.org/blog. Since the blog didn't really have a relationship to the Achievo project management tool anymore (except for the occasional release announcement), and since Achievo.org will soon be completely redesigned, I decided to move my blog over to a new domain.

The new design was created by Almer Kaasschieter. I think he did a great job. Almer, thanks!

If you subscribed to my previous blog, I would like to advise you to update the feed url to http://www.jansch.nl/feed (or click on the subscribe link in the upper right corner).

There are times when I don't blog about PHP but about other subjects, so I've created a separate PHP category so readers of planet-php or other sites that syndicate my blog can use the separate PHP feed:

I also switched from Serendipity to Wordpress. It's not that I'm unhappy with Serendipity, far from it (still using it for our corporate blog) but I wanted to gain some experience with Wordpress as well.

Any feedback on this new blog (negative or positive) is very welcome.
