Testing browser stability with random code
This guy got an amusing idea. He wrote a simple generator of random html and used it to test stability of several browsers. He ran the program against recent versions of Microsoft Internet Explorer, Mozilla / Netscape / Firefox, Opera, Lynx and Links.
All browsers but Microsoft Internet Explorer kept crashing on a regular basis due to NULL pointer references, memory corruption, buffer overflows, or memory exhaustion.
MSIE kept going.
It seems that M$ used a similar method to fine-tune their ‘forgiveness engine’
