  <a href="https://www.youtube.com/watch?v=2OMRWPOSw9s&amp;t=2150">35:50</a> I don’t think that’s right—the magnitude of the cross product of unit vectors is the sine of the angle between them, not necessarily 1.

  &quot;For humans who still write code&quot; is crazy

  &quot;for humans who still write code&quot; is sad but also means this video is for me so that&apos;s coole

  This video is brilliant. It&apos;s one of the best attempts I&apos;ve seen for describing how to think about functions, why to use them (reuse is the least important reason, as you say), and how to design them. The &quot;write the code you&apos;d like to see&quot; and &quot;single level of abstraction&quot; guidelines map almost directly onto my own thinking in this area.

  This is the kind of video that makes me remember why I like programming. Thank you.

  <a href="https://www.youtube.com/watch?v=2OMRWPOSw9s&amp;t=130">2:10</a> having pseudo assembly code filled with Lorem Ipsum is unhinged behavior and I&apos;m absolutely here for it

  Back when I was learning about programming I spent a lot of time thinking about this topic which I never formalized in my head, it stayed as matter of taste I acquired from experience. You just formalized my taste very accurately.

  Learning that code reuse is not the main attraction is also what happened to inheritance. It has to have some semantic value beyond just being DRY.
