#3I'm primarily a Go developer and love the language and will defend it for most use-cases, but to be honest BPF seems like Rust's place to shine.

Re: Show HN: Write your BPF programs in Go, not C
#5In eBPF-land you're going to be calling C functions in the kernel, and using (generally) C data types like structs and null-terminated strings. You can't do loops (loops are unrolled by the compiler), you can't do variadic functions, and you definitely can't take advantage of all the cool Go stuff like goroutines, select, context, etc.
I'm not really sure why you'd want to use this. If you're writing eBPF, you already need to know how to read C kernel source.

It's a low level networking interface

I'm guessing Berkeley Packet Filter: https://en.wikipedia.org/wiki/Berkeley_Packet_Filter
This is why National Aeronautics & Space Administration (NASA) guidance is the following:

To be honest BPF is one of those acronyms that I think might be more recognizable as the acronym than what it actually stands for.
Not quite as much as Radar or Laser, but halfway there.

This transpiles to the native language.
