A resume is a listing of what you have done in your life that could be relevant to the job you are applying for. If that is an online course and a couple of open source projects, then this can be just as helpful to your future employer as a list of companies you have worked for.

To resume means to summarize. Your GitHub profile is not a summary, it is a raw dump of everything that you have done without weighting.

So, of course a resume is still relevant today. And it is still up to the applicant to present himself to the employer, because most of the time the applicant is looking for a specific job when the company is not looking for a specific employee.
