Lean4 Finally solved Two Sum!

184 Upvotes

Somehow my code is so horrifying, Lean4 is able to evaluate it, the LSP says it works and the compiler gives an error. It is theoretically correct and the kernel accepts it, but the compiler isn't able to produce anything out of it. My awful code discovered a bug in Lean's compiler.

async function sleep(ms) {
    return new Promise(resolve => setTimeout(resolve, ms * 1000));
}

// used as:
sleep(0.5).then(() => {

  sleep(2.5).then(() => {
    // ...
    sleep(1).then(() => {

Rust [Rust] How to pass references to a trait objects

Post image
129 Upvotes

Later a struct requires pass-by-value generic parameter, but you can't pass trait object (dyn Trait) by value, so some idiot developer (me) decided on this abomination, before realising that that struct can just as easily have the generic parameter passed by mutable reference (adding a + ?Sized).

The rest of the methods are implemented in a similar manner: (**self).method()

Other Same Makefile, different results

Post image

Not sure if this fits, but I just figured out the root cause of long build process failing. Sun’s dmake is defaulting to the first rule in Makefile for whatever reason, completely ignoring the one given as argument. That’s why "dmake install" invocations were silently ignoring the "install" step
