Hello Emil Moe,
Allow me to share with you some resources where usually i'm diving there.
1- Udemy.com, Udemy is my best resource for a lot of courses i already enrolled. not only this, I'm not easy buyer. as i'm always reading course description and reviews. also i'm getting a look into Course content & results that i will get when finishing the course.
2- One of my best places to learn Ruby On Rails is Codeplace.com, they have good amount of courses and recipes which can push student skills.
3- The most popular website, Youtube.com . . I will never forget it, many courses and knowledge i gain from YouTube it self.
Thank You,
Elayan
