One topic at high level (like in the article, 10-20 minutes?) per week, results in ~50 topics per year. Not sure how many computer related topics you know/want (“The more you know, the more you know you don't know”), but for me, 50 topics on programming seems sufficiently high at frankly a very low effort/commitment.
