@exercism_io is really incredible. My submission was failing it's tests…I asked for mentoring to help straighten things out, and within 15 minutes someone had messaged me explaining my error.

…I worked on the Ruby strings exercises at @exercism_io This platform forces me to slow down and actually logically solve the tasks…

I've always loved @exercism_io because you learn not only the syntax of a language, but also its dev environment: how to setup tests, packaging and build. Fantastic resource!

Exercism is powered by huge team of wonderful volunteers.
