Java: Speed of Math
by ROYVANRIJN on JULY 15, 2012

Last week I’ve created a ray marcher 3d engine which renders the Mandelbulb. And I’ve translated it into pure Javascript a couple of days later. After the translation I decided I should optimize the code a little for speed, so I made some speed improvements in the Javascript code. The main optimization was using an array for the vector3d instead of a class/function. Read more

No use of existing compression algorithms (e.g. gzip / bzip2) unless you include the full algorithm in your code.
Use any language, shortest code wins.

THC-SSL-DoS is a tool to verify the performance of SSL.

Posted on | October 26, 2011 | No Comments

Establishing a secure SSL connection requires 15x more processing
power on the server than on the client.

THC-SSL-DOS exploits this asymmetric property by overloading the 
server and knocking it off the Internet.

This problem affects all SSL implementations today. The vendors are aware
of this problem since 2003 and the topic has been widely discussed.

This attack further exploits the SSL secure Renegotiation feature
to trigger thousands of renegotiations via single TCP connection.
