Cool trick to avoid spam without using CAPTCHA

Posted in Technology, Web by Yatendra on October 16, 2007

It seems its not just me but quite a few people who are not too fond of CAPTCHA. Author of the post linked below has come up with a neat trick to avoid spam without using CAPTCHA. He makes use of the fact that humans are more intelligent than bots; but without asking the site visitor to recognize weird looking letters and enter them in a text field. Instead he creates a simple text field and makes it hidden using CSS, so to human eye it wont be visible but when a bot fills the form it would fill in this field too, as this field has been made invisible from CSS not HTML attribute. In the end he checks if this field has any value then ignores it as spam.

How to market your web application

Posted in Technology, Web by Yatendra on March 22, 2007

These days you can find a new web application (web 2.0 startup as they say) being launched everyday. Quite a few of them rise to fame as soon as a major blog or a social news website writes about it but sadly, in most cases this fame is very short lived. This article on Read/Write web very interestingly divides these web applications into the WAIT list, the WALK list and the RUN list, and suggests some strategies to effectively market web applications belonging to each category.
