if you release an analog stick it actually has quite a lot of bounce in the other direction on the way back. beyond a reasonable deadzone. I'm not sure if I'm expected to compensate for this at the game level or not...

Is it just me, or is AT protocol and bsky being distributed just a marketing gimmick?
What people want is the big community of people.
So even if it's distributed in theory, this is just a single community that lives and dies with bsky servers.

I've released odin-c-bindgen 2.0. It's rewritten from scratch! See the change log here: github.com/karl-zylinsk...
I rewrote it because the old code became a bit too messy. The new version has less bugs, more features and is easier to maintain.

Release 2.0: A complete rewrite: Less bugs, more features! · karl-zylinski/odin-c-bindgen
I have spent almost a whole month rewriting the binding generator.
With this rewrite, the generator is less buggy and easier to maintain.
New features available in bindgen.sjson

Grab your friends and jump in — it’s 90% off right now (and we still don’t know how to turn it off 😅).

This is especially true when doing "refactoring".
To avoid bugs, your code needs to compile as often as possible.
See any initial work as R&D to find the refactor path that lets you recompile and run as often as possible. When you found it, just start over from there.

An underrated skill in programming is learning to start over with the current problem.
I often see people trying to fix their current problem solution. Almost in denial of the solution's basic flaws.
Often its faster and better to just take some notes and start over.

A common thing people don't know about C is that this function is variadic: `int some_func();`
You can throw in any number of parameters (including none)!
You say "accepts 0 parameters" you have to do this:
`int some_func(void);`

There's nothing quite like being able to just copy-paste procedures between two projects and the code just working.
In general, code is easier to reuse in code-bases that just use structs and procedures, compared to any kind of class hierarchy.

People who try languages with a 'defer' keyword tend to overuse it.
It has a cost: The code is harder to read because it is no longer linear.
My rule: Only use defer when there are multiple ways to exit a scope, and you need some code to run regardless of which exit it takes.
