Amazing image resizing

This image resizing technique is absolutely amazing. It is actually not only a technique to resize images, but also makes it possible to make objects (or people) in a picture disappear. What it does is basically take out parts of the image which it thinks are not important. The real difficulty obviously lies in finding the right part of the image to take out.
Once again an image (this time a video) is worth more than a thousand words. Check it out. Your jaw will drop.

Reaction to the Facebook code leakage: Protect your site!

Nik Cubrilovic, occasional writer for Techcrunch, has published a good article concerning source code security in response to the Facebook code leakage I hope none of you missed.
Short summary:

• Use mod_security
• Put all of your code except index.php outside of your web root
• Change the default file type in the Apache (or whatever you use) configuration
• Use 'Deny all' to prevent access to folders outside the web root

For more in-depth information and guidelines how to implement these security measures check out Nik's blog.
