    You can avoid installing an MTA by redirecting the output of your command to a file btw.

      Yeah, that was going to be my next plan if the MTA approach didn’t work. Probably it should have been my first plan.

      I can’t select the wget command for some reason on your site. Seems to be something blocking highlighting.

        Agh, sorry. I just fixed it. I also fixed (most of) the horizontal scrolling in the code blocks by changing to white-space: pre-wrap . Thanks for letting me know!

        Thanks for this post! I didn’t know about these images. Try not to be alone when you watch Grave of the Fireflies; it is a very sad movie.

        1. 3

          I did watch it alone, and I feel strongly that alone is the right way to watch it.

            As long as you went in knowing what to expect!

            1. 1

              All I need is a recommendation from a trusted source, and I’ll watch something. I do not need to know anything about it, nor will I look anything up.

              So I watch with no knowledge, not knowing what to expect. That’s the most enjoyable to me.

              Thus “it’s very sad” is, from such a perspective, a spoiler.

            Phew, that was my plan, so thank you for the warning!!

            Super disappointed that this is a long post about Mindstorms but leaves out one of the key educational devices in the book that’s been all but forgotten in the modern computing landscape - Dynaturtles.

            I cut my teeth on Atari LOGO, where the turtle wasn’t just a static pen you could order around, but a sprite that could also be given velocity, direction, and a daemon like series of verbs called ‘when’ so you could program the turtle to interact with its environment in various fascinating ways.

            Apparently LCSI Microworlds is still commercially available and includes Dynaturtles, but I can’t bring myself to pay what they’re asking.

            Through the years whenever I’ve tried to bring this up, people point me at various other LOGO implementations with similar but not nearly identical concepts like StarLOGO or MSWLogo which embody some aspects of the concept but not the key bits of the concept itself.

            For a nice exploration of what I’m talking about in book form, check out Computer Art and Animation with Atari LOGO at the Internet Archive.

              This reminds me that my notes only cover up to Chapter 5 (of 8 total). Dynaturtles discussion begins in Chapter 5. I’ll updated the post soon with the rest of my notes and scribbles. Thanks for the reminder. Agreed that Dynaturtles concept is really interesting. While reading, the Dynaturtles concepts reminded me of Daniel Schiffman’s book Nature of Code, which uses Processing / p5js to model natural phenomenon like flocking, etc.

                Wow, that (Nature of Code) sounds amazing! Thanks for the pointer! I’ve been wanting to learn p5js for a while.

                1. 2

                  Started working through Nature of Code and it’s incredible!

                  I know enough Java that Processing is pretty easy for me to pick up, and I’m really enjoying the opportunity to explore some mathematical concepts using graphics without having to wrap my brain around C++.

                  Daniel Schiffman is a talented guy. His Youtube channel is also chock full of interesting examples, tutorials, and challenges.

                  Great stuff and just exactly what I need right now since I’m beginning to feel just a bit burned out after ~8 months pushing really hard on Python mastery after hours on top of a fairly intense full time job. Feels really good to stretch my brain a bit on tasks that feel more like play than work :)

              1. 2

                I should read the book! But this post seems to be a long list of bullet points. Maybe an additional editing pass could’ve made it easier to comprehend?

                1. 2

                  My goal with the post was twofold: (1) to inspire others to check out this excellent book, and (2) to simply record my notes so that I could reference them later. I do think the bullet points give a good taste / smattering of some of the interesting ideas in Papert’s book and research. But I also just went through and gave them another editing pass - thanks for the feedback!
