And yet, those "diaries" are an incredibly effective way to control the public narrative.

chen_dev··on API design note: Beware of adding an "Other" enum value
> it gets deserialized as the zero value

It’s more complicated:

https://protobuf.dev/programming-guides/enum/

>> What happens when a program parses binary data that contains field 1 with the value 2?

>- Open enums will parse the value 2 and store it directly in the field. Accessor will report the field as being set and will return something that represents 2.

>- Closed enums will parse the value 2 and store it in the message’s unknown field set. Accessors will report the field as being unset and will return the enum’s default value.

Limits Reached -> PubSub Notification -> Shutdown Sequence.

chen_dev··on The Origins of Wokeness
Not sure about 'I can do it because I am morally superior'. Is it required to be morally superior to have an opposing view?

chen_dev··on Atomic Operations Composition in Go
1) what

#![allow(unused)]

fn main() {

    use std::sync::atomic::{AtomicI64, Ordering};

    let some_var = AtomicI64::new(5);
    
    if some_var.load(Ordering::Relaxed) % 2 == 0 {
        some_var.fetch_add(1, Ordering::Relaxed);
    } else {
        some_var.fetch_add(2, Ordering::Relaxed);
    }
}

Is "atomic operations composition" a real term? Or it's something like "monolithic microservice"? What does that even mean?

chen_dev··on Fixing for loops in Go 1.22
the 'fix' to the example in the README should be obvious, but for reference:

- for _, e := range es {

- pumpUp(&e)

}

+ for i := range es {

+ pumpUp(&es[i])

}
