Hi all,

I had this idea of explaining filter/map/reduce with fruits and graders for a while, and last week finally filmed it. The quality isn’t that great, but I still wonder if this could be helpful to beginners. The idea is not to explain these things from scratch, but rather provide a mental image, a supporting analogy that makes sense.

    I really enjoyed this. Even though I’ve been programming for years now, I found the video really helpful, and I immediately sent it to a friend who’s currently in a boot camp. Great work! I’d love to see more in this vein.

      Thank you!

      If you have any topic suggestions/ideas, please let me know.

        Yeah! Maybe something with recursion using a russian nesting doll and disguised jump cuts? Only half an idea, though.

          I actually had made a video on recursion in the past, with boxes generating other boxes based on blueprints :) https://www.youtube.com/watch?v=vLhHyGTkjCs

            Ha, beat me to it!

            What about sorting algorithms with refrigerator magnets?

              Hmm, could you elaborate, please?

                Sure. It’s a half-idea, but my thought was to explain something like bubble-sort, by re-arranging the order of stacked magnets on a refrigerator. Maybe something like these that have different colors, so you can see visually how the sort works based on color groupings https://www.amazon.com/Tiergrade-Assorted-Classroom-Refrigerator-Whiteboard/dp/B01K70O2HO?ref_=Oct_DotdC_3i1i9_0_09c36237&pf_rd_p=89def296-fb7d-550c-8a3f-9de7cb1ee35d&pf_rd_s=merchandised-search-5&pf_rd_t=101&pf_rd_i=3737161&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=2N3HRCNB9X0DX1K6ZZ1M&pf_rd_r=2N3HRCNB9X0DX1K6ZZ1M&pf_rd_p=89def296-fb7d-550c-8a3f-9de7cb1ee35d

                  Interesting, I’ll think about it! Thanks!
