CPS is a cool technique, and makes advanced constructs like call/cc trivial to implement. Using CPS techniques in code can feel like magic. But CPS isn't really the state of the art for functional compilers anymore. It's comp

> I think the penguin believes Joao is ... a penguin as well This idea seems completely ridiculous to me. Penguins have eyes, they can obviously see that a human is not a penguin. But it seems like this is a common idea for some reason.

No, the equivalent go code would be package main import "fmt" type Yer[T any] interface { Y() T } func foo[V any, X Yer[V]](x X) V { return x.Y() } type X struct { y int } func (x X) Y()

My understanding is that RAID1 is just a mirror, and all disks have identical contents. Are you talking about something else?

I don't necessarily agree that testability is the same thing as modularity. In my experience, tests that focus on one module in isolation and try to fake/mock all dependencies, including other modules in the same system, tend to b

Rust has a similar problem, where any future can be dropped at any time in async code, effectively cancelling the future. This means all async code has to be ready to be unexpectedly cancelled at any await point, and implement any defensive

I have to say, I am not convinced by this article that async composes better. The nice thing about green threads/fibers is you can make concurrency an internal detail: a function might spawn threads internally, or block, but the caller

IMO, any program using naive timestamps is probably doing something wrong. Same with fixed offsets (except UTC obviously). For local time zone, how often does the local time zone change, and you want to modify all timestamps in the system?

I really like Go's "time" package. The only pitfall I can think of is that it doesn't really handle overflow at all. https://pkg.go.dev/time
