> I'm not into types [in Python] In Python type hints are just that: hints. mypy is a very poor static analyzer, and a lot of Python code (especially in frameworks like Django) is inherently dynamic and cannot be type-checked. And t

For tail recursion, you can use this snippet of code: class Recurse(Exception): def __init__(self, *args, **kwargs): self.args = args self.kwargs = kwargs class Terminate(Exception): def __init__(sel

"new" when talking about a repository with 15 commits, the last one being 3 years ago. It is obviously a toy experiment and it took my 5s to realize that. While it does not say "this is a lisp", it also does not say &quo

A chainsaw is not safe. But you can learn to use it safely. Replace chainsaw with: - knife - guns - C programming language There are tools and methods (and a lot of discipline) to ensure safety in C: - compiler's sanitiz

You know sanitizers and static analysis tools exist, and have existed for decades, and have been the basis for the work done in Rust and other "safe" languages? Also, a disciplined C programmer will always keep the size of the buf

Take a car, the engine is the OCI runtime, crun, containerd, etc.. The whole car is Docker, or Podman. Kubernetes is the city where the cars run. --- EDIT: For more details, OCI (Open Container Initiative) defines a few things: - an ima

ORMs (especially the Django ORM) fulfill 95% of my needs. For the 5%, I use raw SQL via the ORM's escape hatch (which Django and SQLAlchemy provides). To be fair, my needs aren't that complex, I do mostly CRUD on database tables,

An interpreter with a JIT compiler is able to do more optimizations because it has the runtime context to make decisions, while a AOT (ahead of time) compiler will not know anything about what happens at runtime. This is why some JIT'd

Thank you. Your library seems nice. Unfortunately, I have to say it... I hate YAML with a passion, k8s, github actions/gitlab ci, ansible, etc... When I'm doing ops jobs, I feel like I'm coding in YAML. Btw, this hate for YAM

So you deny that the industry used Python to build serious production softwares? Understood, no need to argue then, I don't think any amount of proof would change your mind...

Type hints communicate intents. They can be used for many things. Django-Ninja use them to do dependency injection and generate schemas for your API (using pydantic). autodoc use them to generate the documentation of your function. etc... I

You can express the same idea in english and german and french and ... But if you try to invent your own language (like Tolkien did), you are not "expressing an idea" (aka: speaking), you are creating a framework to express ideas.

Just for the record, this will also bypass the monetization I get from my articles. But I don't mind, thank you for sharing this so more people can read my work. I'll keep publishing on Medium though :)

by linkdd 3y ago
Then don't, I'm not forcing you. I use Medium because I can monetize easily the articles I write, though it's not much (currently around 10-15$/month). I'm not doing it for the money, but it's still nice.

The rust-analyzer extension for VSCode is quite good for this. Though, I should try to use `quote_spanned!` instead of `quote!`, but I'm kind of a newbie with proc-macros. As for your take on the visitor pattern. In my previous code, I

HN removes the friend tag in the URL so I can't share the "no-paywall" link unfortunately. Though, this is fine by me. I don't mind people bypassing the paywall, but it's a source of (rather small) income for me :)
