delve is a very powerful debugger. The real power is in it's API and extensibility.

maybe everything was just a build-up for me to build end to end encrypted VPN(s) with BPF and kTLS, I already have the fundamentals, but it is a very ambitious project and I need to think very hard before starting.

I am quite proud of this personal blog I have implemented. Performant, minimal and has good articles.

I write articles in markdown, one push to GitHub deploys it here: [link in comments]

Just because your eBPF program compiled, doesn't mean the verifier will allow it to run. And verifier talks some enchanted languages. I'll let the LLM figure that out.

never try to patch a TCP packet on the fly, worst mistake of my life. All I wanted to try was "I have the TCP packet, how about I change the Source IP" and now I am fighting check-sums.

I think wrapping my head around Go's ABI is harder than I thought. On top of that working with data using C is comparatively harder too, and then on top of that, eBPF verifier makes life hell.
