Can you explain more about "advanced reference libraries", and how they interfere with the benefits of option types?

Can anyone provide some insight into possible motivations for why the authors may have chosen to use a shell here? I'm struggling to understand what value it adds over representing mda_command as an array of strings and execving that.

I know basically nothing about medical technology. How likely is this to actually end up making a big difference? How does this type of development compare to new battery technology, "graphene", and similar topics in electronics

The difference is that you can't accidentally use an option as a pointer without checking it first, and when your APIs specify a non-nullable pointer you can rely on the callers to have checked for null. When you're reading or wri

Can you give some more details on what the design problem is here? It seems to me that nullable references are isomorphic to having an option type with non-nullable references, but prevent accidental unchecked dereference. What are some of

You may be interested in the `im` crate for Rust, which implements efficient copy-on-write structural sharing, falling back to in-place mutation when there are no other outstanding references. https://docs.rs/im/14.1.0&

Rust is a huge help with exactly this problem. The compiler will clearly tell you exactly where you've made a mistake if you give it code that violates the ownership rules, like trying to keep a reference past its valid lifetime. It t

I actually have no idea what you're alluding to here; can you be a bit more explicit for us oblivious readers?

I'm not familiar with the implementation details of QSBR, and I've never used liburcu-qsbr, but what I've read about it tonight sounds a lot like the im[0] crate in terms of behaviour. The behaviour in im is a data structure

What structure do you believe Haskell forces on your code? My experience with Haskell is that it's the most expressive and flexible environment for exploring different ways of structuring code that I've ever used. I've seen

The proposed fix is that you don't deploy code that the type system can prove is broken, and the person performing the refactoring needs to do additional work rather than pushing out something that will fail in production. My reading o

Assuming struct A has a reference to struct B, memcpy is a fine way to move struct A, and struct B cannot be moved while borrowed. Here's an example I put together demonstrating this: https://play.rust-lang.org/?version

How long would you expect someone to need to write code that makes a few HTTP requests (or read files or whatever other data source is specified), some kind of parsing or decoding (probably JSON) to get the URLs for more requests, and spawn

These kinds of nuances can be a bit subtle; I hope I managed to come across as polite correction instead of attack. :)

I feel confused. Are you really saying that your justification for PHP having a consistent design is that, on its seventh major version, twenty years into its lifetime, an effort has been started to attempt to establish consistency by remo

While I agree with most of your comment, I think you've misinterpreted the intent here: > Until I list the ones it doesn't. Or are they not "real"? My reading of the original post is asserting that there is a specific

Re-reading your comment, I did overreact, and assumed that you were implying a position that you didn't actually assert. I'm sorry for assuming that you were advocating for a pro-death position. If your comment wasn't intend
