Love computers and coding.
While I'm particularly passionate about Rust, it's not the only language I work with.
Recently started loving embedded programming

Time to spend all of the money you’d normally spend on regularly priced RAM upgrades on sponsoring devs building oss + native Rust (or swift, or go) desktop UI frameworks/toolkits instead!
(Then only the rust developers are sad we need more RAM for actually compiling the apps)

It would be hilarious if spiking RAM prices were the cause of a move away from Electron/webview-based apps to native apps. I've seen arguments from gamers* that unoptimized games right now are on the verge of unethical*.

🦀 Love the compile time assertions in Rust
Instead of panicking at runtime for invalid constant values, catch it at compile time:
``rust
const fn get_top(freq: f64, div_int: u8) -> u16 {
...
assert!(
result <= 65535.0,
"error msg"
);
...
}
```
