It's been a long time, but I've always cherished our late night conversations at the Alexis Park. Truly a great hacker. RIP my friend

I'm really sad, even if I never met him personally and only knew him from his talks, his software and of course his blog.
I had hoped that after his illness he would be granted some time for personal life and recovery — which makes this news all the more shocking.

His excitement and deep interest in things from cisco to web security to life was inspiring.

Sad news. I wonder if his projects (e.g. dietlibc) will continue development or not...

While he was a dividing personality with strong opinions, he had his heart in the right place
RIP

I never really knew felix, but mob says he was a pretty cool guy, and we miss him already.
Thank you felix for everything you did for mob :)

He was a good hacker but also a HUGE, arrogant jerk who treated a lot of people quite badly.
What sad news.
I met FX many years ago during a Black Hat event. At the time, I was working on a class of vulnerabilities related to zip archives. Not only did he know exactly what I was on to, but he was able to articulate the actual issue and explain what was happening behind the scenes and why my exploit was working.
A true legend.
