YSlow!

July 29, 2007 at 3:18 pm · Filed under Firefox Extension

Yahoo! has recently released a tool called YSlow which helps u to optimize ur website.  It is a firefox addon which is integrated with the most popular Firebug web development tool. It is pretty useful for finding the performance issues of the website and also gives us optimization advice.

The below listed 13 rules are identified by Yahoo’s Exceptional Performance team for making the web pages ultra fast.

  1. Make Fewer HTTP Requests
  2. Use a Content Delivery Network
  3. Add an Expires Header
  4. Gzip Components
  5. Put CSS at the Top
  6. Move Scripts to the Bottom
  7. Avoid CSS Expressions
  8. Make JavaScript and CSS External
  9. Reduce DNS Lookups
  10. Minify JavaScript
  11. Avoid Redirects
  12. Remove Duplicate Scripts
  13. Configure ETags

I believe YSlow! will become the most popular helpful utility for webmasters/site administers/developers for optimizing their websites.

Is Captcha Secure?

July 22, 2007 at 9:17 am · Filed under Spam

CAPTCHA stands for Completely Automated Public Turing Test To Tell Computers and Humans Apart is used to ward off automated bots/spammers from repeatedly doing the same task.

CAPTCHA is felt as a secure mechanism to prevent comment spam in Blogs, protecting repeated website registration, prevents dictionary attacks. After reading this blog I realized that captcha cannot be trusted for security. It seems they are pretty much easy to exploit. It appears that now spammers have found a way to overcome CAPTCHA systems, and they have created 15,000 bogus Hotmail & Yahoo accounts. So if you are using captcha to exploit automated spammers, reconsider your approach and follow some other security measures. One good method for dealing with the problem would be to use Bayesian filtering which is considered as the most effective Spam filter. If u would like to learn more about Bayesian and other Spam filtering techniques do check out this article(s) by PaulGraham.
