Its classified, but the second hardest was simulating Dynamic nuclear polarization, ab initio.

The problem I'm currently trying to solve, building a business around a novel data protection mechanism using ML based encoding while continuing to do research on it.

  If you're serious about building a business for this technology you need to realize that people who are interested in trust, data provenance, digital signatures and verification systems are looking for signals of credibility, trust and reliability - as such hosting this on a domain "lyfe.ninja" and having "by lyfe.ninja" written everywhere sounds like a 14 year old script kiddie created this and regardless of whether that is true or not, destroys any credibility and trust straight away

I used ebtables and packet labels/connection tracking to allow our in-house network VPN/Web servers to function seamlessly in our dual homed (but not BGP supported) internet connections, each with different public addresses and gateways. It's now stock functionality in VPN/Firewall appliances, we ended up with SonicWall, but at the time it nearly melted my brain. A second hardest was writing a cooperative multi-tasker for Turbo Pascal programs under MS-DOS.[1] It made a copy of the stack, and the first time it returned from spawn twice, I was really, really confused.... until it dawned on me that it was actually working as designed! There was a really weird requirement in an upload protocol I was using that required knowing how long the file was, before I was even done generating it, so I built a text piping engine to allow that to happen, and Tasker was part of that.
