Sounds like a great way to get dozens of dependencies before you even write a line of code

And then bisect fails because it finds one of the many commits that broke the test before the actual regression

10 dagen geledendiscuss

Suppose we have a failing test. For many commits, gp carefully separated their change that would break our test, from the change that would fix the test. At some point, someone forgot to run the tests, and introduced a commit that broke the test without adding a second commit to fix it. Now it's treated as a "pre-existing failure," and many more commits are added on top.

How would you identify the commit that broke the test?

Of course, but this thread was in the context of someone "carefully curating" their git history

That sounds like it would break bisect

I couldn't find anything about this from a search, do you have a link to the bug tracker or something?

> I must admit I'm a little surprised how many people seem to disable secure boot.

To me, secure boot is the setting that I need to remember to turn off before installing the OS, but I would be willing to be convinced otherwise

Hmm I wasn't familiar with join, but it looks like you still need join + fmap for the construction? I believe fmap would also need a generic method

It's (sadly) still not possible to express monads with this change, since generic methods can't implement interfaces. You'd probably want something like:

    type Monad[T any] interface {
        Bind[U any](func(T) Monad[U])
    }

However this requires the Bind method to be generic, which still isn't allowed in an interface

> Why would there be paranoia when writing blocking code with async?

In languages like JavaScript, you have to be careful to avoid blocking the event loop, and use something like worker threads for CPU-intensive tasks. Otherwise you will end up with long tail latencies. In Go, the runtime automatically manages this and can suspend and resume long-running goroutines.

> naively accessing a global value can lead to race conditions

Fair point that the language doesn't automatically catch this, but that's what a mutex is for. In return you get actual parallelism that can use all your CPU cores

> Your entire codebase is now a surface area that is at risk of being blocked

The point of goroutines is that they can freely block when needed. It's not like async where you have to be paranoid at every moment about writing blocking code

Interesting, thanks

Also C++/Java static initialization, C# static constructors, or Rust global variable initialization, ...

Most languages have this feature Afaik

I use lowercase for my personal environment variables. It works well since most programs only depend on variables in all caps. Hadn't thought of using MY_

I really want to like Helix, but I wish the developers paid more attention to performance, or were more receptive to outside contributions. Helix can really chug, even on small files, and the perception in the community seems to be "it's written in Rust so therefore it's blazingly fast :rocket-ship-emoji:"

Which aspects of Rust syntax are adapted from ML? Semantics sure, but to me the syntax seems a lot more similar to C++ (e.g. semicolons, type parameters using <>, etc.)
