one odd problem with rust i often have is i get so many nested if statements.

C would let you do some fancy formatting tricks with ternaries or short-circuit logic (or even goto), but rust heavily encourages just nesting if statements to express your logic. early returns also don't feel very rusty.

i suppose there's other factors too

1. rust neatly abstracts away other stuff, like string manipulation and lists checking, so what might've been two if statements and 7 function calls is instead two if statements and two chained method calls.
2. rust adds two more kinds of if statements: if let and let else. additionally, if statements can yield values, absorbing the conditional ternary operator.

i just had an extraordinary silly idea.

level-two compiler optimizations.

if the compiler detects you're compiling a compiler, it optimizes your code generator to produce optimized code

this sounds awful for deterministic builds

inexplicable power outage while i'm programming, suddenly really glad all the commands i need have a global cache and an --offline flag

god you could do so many stupid things if you bypassed the standard filesystem abstractions and parsed inodes manually.

load bearing metadata

not because it's necessary, but because the process of trying to choose a default causes everything to break

they should make wine but for running solaris executibles on openbsd, i think that would be funny.

rj45 is such a funny connector if you think about it. it was designed for telephone switching in the 70s and 80s and it actually is fairly reasonably designed for a telephone signal connector. But it became used for Ethernet, and more Ethernet, and faster signals, and now we're able to send 10gbps down this little 8 pin jack from the 70s, and I'm surprised that it still works for this purpose

did you know? rust has a do while loop! you can use it with this syntax:

while { 
    statements();
    statements();
    more statements();
    condition
} {}

here’s an example:

fn main() {
    let mut i = 0;
    
    while {
        println!("{i}");
        i = i + 1;
        i < 5
    } {}
    
    // Expected output:
    // 0
    // 1
    // 2
    // 3
    // 4
}

c programs are often criticized for using too much global state.

but in the case of argc and argv, it's an interesting inversion, as most modern languages actually allow any function access to the command line arguments.
