I really like working in Scala. It allows me to come up with elegant, functional code that is also concise and type safe.

I learned to program on embedded devices, and later moved to iOS development in Objective-C and Swift. Most recently, I've been exploring functional programming in Scala. I'm interested in security principles and applied cryptography. And if I can ever find some spare free time, I would love to try out Rust!

I been using Rust both at work and as a hobby for a while now. Its an awesome project that makes it easy to learn and contribute, and improves really fast while remaining compliant with its principles.

Math teacher turned programmer. Fell in love with Rust while listening to Steve Klabnik talk about its design choices. Eternally grateful for helpful compiler messages. Not tall enough to write multi-threaded code.

Rust is a language that feels as comfortable as the next Ruby. While I can't say I'm an expert quite yet, I've taught a university course in it, so I hope I've picked up enough skill to help beginners out.

I love Ruby and have been using it professionally for more than 10 years. I also have been spending time on how to write a easy to read and easy to extend Ruby code. I am new to mentoring and a non-native English speaker. Please excuse my brevity. If my feedback to you is rude, first I am sorry and second it was not my intention. Please do reach out to me, it gives me an opportunity to learn through feedback for mentoring.

Although Python wasn't my first -- and won't be my last -- programming language, it remains my favorite for introducing others to the joys, the pains, the infrequent ecstacies, and the occasional terrors of life before the REPL.

Python is the first language I taught myself, and the one I used at my first job. I love its relative accessibility to newcomers and the huge ecosystem you can grow into as you learn it!

I have a sysadmin background (on Linux and Windows) and I began learning Python about a year ago to automate tasks. I really like the breadth of the use that you get in this language, and how easy is to write clean code.

Everytime I wanted to do some quick automation I always choose python because it is simple, relatively easy, and fast enough to do the automation. This has saved me a lot of painful time if I were to do it myself manually. I also like java and currently learning some C.
