Testing something is the best way to prove that it behaves correctly in all the cases you can think of. Relying on your own (fallible) understanding is dangerous. Of course, there may be cases you didn't think of where it behaves incor

Runtime errors? As far as I know Gleam will never present runtime errors unless you manually add `todo`, `panic` or `let assert` statements. [1] I feel you on the macros, I have wanted them too, but I respect the language creator's com

Have you given Gleam a try?

Gleam has a subset of OTP functionality already [1]. It also compiles extremely quickly. I haven't made any huge projects yet, but I've used some fairly chunky libraries and everything compiles super quick. [1] https://

Yes, I agree, insertion not moving things is a very useful feature of deques. It allows you to keep items with deleted copy and move constructors in a container that has good cache locality.

The word makes perfect sense, somebody just used it wrong. Don't let's go down the post-modernist "nothing means anything" route just because some people are too partisan to use words properly. What the person should hav

The C++ testing framework Catch2 enables this kind of testing. The first time I saw it I couldn't figure out how some of the tests would even pass. It turns out that using some evil macro magic, each test re-runs from the start for eac

Can you explain why you don't like `use` but you would like an `await` keyword? As far as I can see, `use` is a superset of the `await` transformation that just happens to work in a lot more situations. It circumvents callback hell whe

LLMs don't seem to be very impartial so far. Quite the opposite in fact, they're entirely beholden to the prejudices of their trainers.

I'm not an expert in Clojure or Rust, but an interested outsider in both, so please don't take my question as a challenge but a genuine curiosity: Doesn't the focus on immutable data make most of the ownership stuff redundant

That's on a very cold day. Depending where you are they may be more common or not. But in the UK, they're pretty uncommon. COP of ~4 is much more common.

Yeesh, that shows a pretty comprehensive dearth of humour in the model. It did a decent examination of characteristics that might form the components of a joke, but completely failed to actually construct one. I couldn't see a single i

I agree on all points, especially the idea of using Lua as a first language. It has so few features that you're really forced to focus on fundamental concepts like functions and (simple) data structures. And its flexibility to be used

In the UK a hybrid is increasingly popular. Start the rave at 2pm, end it at midnight, but it's in a dark room so it might as well be 4am. Usually in some semi-temporary space (e.g. Printworks, now defunct and moved to Drumshed). I agr

Interesting note: they don't market it as AI. They market it as Apple Intelligence. I think this is deliberate. So it seems they've already taken your advice (albeit with the 'wink' of using the same initials).

I think it's much easier for Apple to sort out their AI and add this to iPhone than it is for OpenAI to figure out an entire mobile ecosystem where Apple has a ~15 year headstart and use their AI in it. I agree Siri isn't good, bu

I'm not sure what you're getting at. They banned certain advertisments at a particular time of day. They didn't ban parents from giving their children whatever thet want to give them.

Pragmatism is more than just giving people the quickest way to complete their task. There are other axes to consider, such as the simplicity of the compiler and the uniformity of the language experience. These contribute to the maintainabil

It has some syntax similarities to Rust, but it has GC so there's no borrow checker (or any of the associated syntax). It is also fully immutable, unlike Rust. It leans heavily on sum types, just like Rust. Also expression-based syntax

Agreed. OP said they don't know Lua, but if you know Javascript it can be picked up in a day or two. And it's really a lovely experience.
