    Slide-y dog and lighting! The new light rendering tools for Unity 2D are really nice. So far I've written maybe 10 lines of code and I've recreated most of what I had in Godot (and previously Amethyst) 😎

    When have you ever actually intended to take a screenshot of you lock screen vs mash buttons to turn off/on your phone/alarm? 📱

    Trying out Unity again (it’s been a few years). So far so good—a lot of improvements for 2D games and sprites. Using FFI to call into rust dylibs also doesn’t look _that_ bad (although sharing memory might get interesting). Helps that it’s C#.

    After using game engine for 2D for a bit—things that godot gets right: scenes, instancing, native bindings, camera. Things that makes frustratingly hard: tilemaps, pathfinding, collisions, accessing other nodes.

    6/ Applications of this effect in product development is an interesting angle. How might we build really powerful tools that help users achieve mastery faster? Keyboard shortcuts come to mind.

    5/ The most interesting takeaway for me—what does the spacing effect say about how memory works? Are we just more motivated to remember because it's a challenge to recall information after a few days? Is this actually some other effect?

    4/ When applying the spacing effect to the classroom, it's less clearly useful. Something about general education makes the spacing effect less effective than rote memorization tasks. Some studies failed to replicate the benefits of spacing effect in a classroom context at all.

    3/ It's nothing new—the earliest experiments date back to 1885! Since then numerous studies have found similar results. But, looking a little closer, you shouldn't believe everything zealots write on the internet.

    2/ Spaced repetition of information over a larger time scale (days) improves learning/recall compared to cramming (many repetitions with low/no delay). You've probably seen things like Anki, a flash card system which uses this 'spacing effect' to help people remember better.

    1/ Mini paper review: The Spacing Effect (Frank N. Dempster, 1988). After hearing about the spacing effect several times recently, I was curious to see what some of the literature actually says about the usefulness of this phenomonon.

    Broken collision detection + pathfinding is so entertaining :cryy:

    One thing that using nascent programming languages teaches you is to read a lot of code to figure out how things work. Because they’re early languages, there isn’t a ton of docs, stackoverflow, blog posts to help. I’ve found this to be a useful and transferable skill.

    It’s nice being in NYC where the avg overheard conversation doesn’t revolve around tech and my friends aren’t really sure what I do 😂

    I really like Rust's conditional compilation story--it's quite powerful. I was able to decouple the dependencies of a library by a few features which cut down the compilation time and (presumably) bin size all with a few lines of code and small config change.

    I like that amazon delivery takes a picture of the package when it’s delivered. Not pictured: my dog going ballistic while a stranger lurks outside the door taking a picture. 😅 sorry.

    Had a long elaborate dream about SSL termination and terminating ‘at the edge’ which makes no sense at all. I guess that’s why they’re dreams.
