We use FFMpeg a lot. I stumbled on an article about the guy who wrote it when the article link appeared on HN (how original) a month ago.

Fabrice Bellard really has an amazing track. Not only did he write FFMPEG, but also QEMU, along with pi calculation and tiny c compiler.

Two recent projects did catch my attention:

LTE Base Station Software which implements through software a quasi 4g network. For public or private. Which could open where GSM was closed.

He also made the JSLINUX project. Which is about emulating a x86 linux on javascript. Sadly it isn’t open source. But still remarkable.
