Sqlite is probably the one C project I totally trust. But, yeah, "cloning" projects is losing proposition (even more if open source). I wish a sqlite-like on rust? yeah, but not a clone, but in spirit (exist so much we can improve

I was arguing against the idea of "string are implemented differently by different languages, so WHICH one choose?". A safe one. Your sample is that - except I think is better if is a utf-8 string, but this one works for me too-.

Any complex structure past int/floats requiere conversion. Heck, even floats and ints (for example: oCalm and anybody with more/less bits than JS). So, given this is a fact, the best course of action is chosen the most safe altern

Yeah, I use azure so I can get build support for linux, windows, osx. I wish I could simplify all that, but with windows I need call native C++ toolchain (using rust).

Also: A good visualization(light!) of structured logging. I move to it and suddenly get harder to inspect my logs because all this stuff presume I will deploy a heavy ELK stack or something.

Rust have the same issue (for other reason) and the solution here is using arenas. Maybe adding an arena in the std library is enough to placate the need for end-users?

People want a table, like in rdbms. Hashmap is what them get. The properties of it (only useful as a direct index) is too narrow for the kind of use that in Langs like python has, where a dictionary is used everywhere (like a vector). How s

Agreed. The most important take, IMHO, is that you have structured/disciplined way to do things, and do it everywhere. It could lead to a lot of code (the part about all that validations upfront), but having a distinct and regular styl

To be pedantic, is not a contradiction. Is a sign of problem with the design? Probably! Most likely! But the relational model CAN'T say it. The normal forms are properties of the way you can do the design, but can't go that Deep.

No, is not a contradiction. Is like say "Is wrong to store a large json in a cell in an array, that make it not an array". A relation is A VALUE. That is. The atomicity of the data INSIDE each "cell" is orthogonal to the
