- <span class="badge blue">featured</span> ever wondered how Terraria renders its worlds? or how editors like Tiled manage to make painting tiles so easy?
- I recently got a question from my someone telling me they doesn't understand why `*x` does not read from the pointer `x` when on the left-hand side of an assignment.
and that made me think,
### what's up with `*x` not always meaning the same thing in different contexts?
- I've been thinking recently how cool it is to be able to single-step into Unreal Engine's source code and edit it while you're working with it, and how uncool it is that I can't do the same thing easily in the Rust world.
after all, aren't we just dealing with a bunch of code running on the computer? why not let me poke at it?
### systems are just a bunch of code

- last night I couldn't sleep because of type theory. in the process of trying to write down my thoughts, I ended up discovering a class of types which, to my knowledge, no language implements.
### OR-types
[what the hell do you mean, aren't sum types exactly that??][page:programming/blog/or-types]
