Template errors with g++ vs clang++ are what made me abandon the gcc toolchain for my dev environment (I still build against both compilers in my CI/CD though). Rust wasn't even a thing (not as hype and mature) at that time. Rust

`every()` returns true if every item in a collection verify a predicate (this is the `foldl1 (||)` part of the example). `map()` applies a function to every item in a collection and returns a new collection. What I confuses me about the Has

Haskell is nice, it's type systems allows the developer to prove the properties of their algorithm. But it's so hard to read when you're not used to the syntax, compare this to a Javascript/Typescript solution: const

This is exactly why it's a hard question to answer. Innovation is not always "new problems to solve", but more often "new clever ways to solve a problem", which rules out number 2 IMHO. For example, Kubernetes was a

Same except I don't bin it, I put it in the "projects for fun" box. NB: "What's the competition" is a very hard question when you're trying to innovate.

Was looking for a tool like this, thanks!

Thanks for the insight! Didn't know strum. But yeah, I tend to do more work at runtime than compile-time, which is not really the way to go in Rust.

Yep, I'm still new to serde and the Deserialize workflow :) I come from highly dynamic languages, and even when I was doing C/C++ 10 years ago, I would do more at runtime that what could be considered "best practice".

I stayed on WSL1 for the shared localhost. And WSL2 still have some performance issues related to memory usage and Disk IO. But yeah, I agree, Windows 10 has a great UX. I switched to windows because of the WSL, and I end up using it less a

What about user-supplied JSON schemas? You can't add types at runtime. Also, JSON schemas allows you to encode semantics about the value not only their types: {"type": "string", "format": "url&quo

Git Bash integrated in VS Code works very well. For Rust/Go/Python/Javascript development, I've never had to rely on any workaround.

Of course, but what's the point? I use WSL for 3-4 programs, that's it. My entire toolchain is Windows-compatible, and installed through chocolatey with the default configuration.

But the Rust type system cannot fully express a JSON Schema: { "type": "object", "oneOf": [{ "required": ["kind", "foobar"], "properties": {

Rust syntax is weird. Weirdly good and sometimes bad. I'm currently designing my own toy language and writing the compiler (to LLVM IR) in Rust. Representing the AST with Rust's sum types is so simple. Visiting that AST through pa

Function calls to another module ALWAYS introduce a breakpoint so the BEAM (Erlang VM) can check if the target module is up-to-date, and perform hot code reloading if it isn't. Therefore, every function is interruptible (implicit async

Thank you for the clarification. But still, since it's all about composition, the simplicity is a direct consequence IMHO.

> I might describe it as “pathologically easy” to compose functions in Haskell Maybe because "composing functions" is the whole point of category theory, monads and Haskell?

This. The main selling point for me was the "zoom in/out" aspect. Instead of having a HUGE UML diagram, you have a bunch of small diagrams, each focused on a single part of the described system and the interactions between it

by linkdd 5y ago
In Erlang/Elixir, every function from another module is async by design, and the await is implicit. This is by design to allow for hot code reloading. This is a very sound design choice because true concurrency is achieved through the

No cowboy would treat their servers like cattle. Joke aside, the Linux kernel is mainly developed in C and runs in production everywhere.
