"For us, open source isn't just a business model; it's smart
engineering practice." -- Bruce Schneier
I hope I'm not the only one, but I think the NSA (and other state
actors) intentionally introducing systemic weaknesses or backdoors
into critical infrastructure is pretty ... reckless. I really can't
figure out if it's arrogance or just plain naivety on their part, but
they seem pretty confident that the information won't ever fall into
the wrong hands and keep pushing forward.
So for me, this is an area I've very interested in seeing some progress.
I think most people don't realize that if you only care about 1G
performance levels, commodity hardware can be more than fine. Linux
netfilter makes a really great firewall, and it's the most
peer-reviewed in the world.
