Club Q Shooting
Colorado Springs PD tackled the man who stopped the Club Q shooter, handcuffed him, and locked him in a cruiser while he screamed to be let out so he could find out if his family was safe.
Given all the drama that's been happening on the bird site, this is starting to feel more relevant than ever.

Incredible x86 emulator written by Fabrice Bellard in Javascript runs Linux: http://bellard.org/jslinux/
In the last 10 years since I originally posted this Fabrice has added multiple distros to this, real networking ability, support for many programs including compilers, a web browser, and the ability to run X windows, all running in the browser. This is the same guy who made QEMU, ffmpeg, Tiny C compiler and a faster way of computing Pi in hexadecimal. Have fun.
