Happy #Hactoberfest, everyone! 🎃

Let me introduce a list of the best open-source findings for September 2019.

If you want to have more awesomeness, including new and useful open-source tools, great articles, and excellent talks - you can join my telegram channel called [@OpensourceFindings](https://t.me/opensource_findings) ([mirror link](https://tlg.name/opensource_findings)).

In this list we will discuss: Rust, Swift, TypeScript, JavaScript, Go, Scala, and Python. 
This includes web and mobile development, developer tooling, and Big Data tooling.
