Ah yes, the original project. herb (backronymed to the Hackable wEb seRver Binary) is my web server that I built in Rust. I generally work on it on and off.
I don't intend to use it to replace any of my HTTP servers at all but as a way to learn about the HTTP protocol and its idiosyncrasies. herb is a very interesting project and one that was first started on an Android smartphone with Termux and a keyboard attached.
It really reinvigorated my interest in programming again.
