Excerpt:

This is a reconstruction -- extracted and very lightly edited -- of the "prehistory" of Rust development, when it was a personal project between 2006-2009 and, after late 2009, a Mozilla project conducted in private.

The purposes of publishing this now are:

• It might encourage someone with a hobby project to persevere
• It might be of interest to language or CS researchers someday
• It might settle some arguments / disputed historical claims

Rust started being developed 18 years ago. This is how it looked until 14 years ago, where I believe the rest of development is on rust-lang/rust. The first Rust program looks completely different than the Rust we know today.
