CISSP Review

The CISSP has become one of the hottest certifications to have (especially in the DC area) because of the growing budget for information security. But the CISSP exam itself has some major flaws, leading me to wonder if this is a valuable certification for individuals, companies, or society at large. (Disclaimer: I am a CISSP.)

Prefix Sum Kernel Visualizations

I am taking the Coursera HPP course, and I just finished watching lectures 6-2 and 6-3.

I put together some cleaner, larger visualizations to show how these kernels work. Hopefully this will be of use to other Coursera students.

reCAPTCHA Is A Blight
