Same here. From time to time I look at it, like the premise, try to start using it and stop after a few hours 😔
I want to like the Swift programming language. I just c@n't do it.

When you use coding agents for something that produces the bulk of the code of an application that will be used for years, also factor in the technical debt that you are happily accumulating. When you use LLMs an an aid, you could, on the contrary, improve your coding culture.

After trying to pick up Go again, I'm more convinced that it should have a .? operator or at least some linter rules to enforce nil checks on pointer receivers.
This would stuff like `myVar.GetX().GetY()` (where GetX/Y returns pointers) at least a bit more safe ...

www.seangoedecke.com/not-your-cod... This resonates quite a bit with me. The best advice I've ever seen was from a Jane Street tech talk about their internal code review practices (encouraging reviewers to push to the branch rather than just leaving comments

I had to crop some margins on a PDF and this Java app with its Swing UI just worked... github.com/mbaeuerle/Br... autodetect the content area, overlayed all pages to manually adjust the crop area if necessary. I wish all software was like this 🥹

So much this. It only pays off much later, but whoever is going to maintain your code (even your future self) will thank you for it :)
type-safety is painful when you are migrating from unsafe to safe, or even when you are creating software from scratch, but it's marvelous when you are maintaining, refactoring, testing or explaining code

While you may hear a lot of harsh words about Rust is this rant, that doesn't have to mean it's a bad language. Rephrasing the classic: there are two types of programming languages: ones that people c...

ok lol. I was enjoying a bit of recreational Odin programming and thought to myself: would be cool if it had some automatic memory management for places where you don't care for performance. 50 lines later we've integrated www.hboehm.info/gc/gcinterfa... as a custom allocator 😅

trying for hours now to get dune to link a c library. but for whatever reason it's building the executable but running it results in unresolved symbols.
I hoped the following flags would be enough in an (executable) stanca? (flags :standard -cclib -lmruby -ccopt -L/opt/homebrew/lib)

TIL that you can use OCaml's PPX extensions in quoted strings. I.e. for ppx_string:
[%string "This \"%{value}\" will get replaced"]
is the same as
{%string|This "%{value}" will get replaced|}
(all credit to tarides.com/blog/2019-05... which is a really good read)
[%string "This \"%{value}\" will get replaced"]
is the same as
{%string|This "%{value}" will get replaced|}

I was just trying to create a small mobile website with charts on them and realised that the whole left-to-right concept for line charts is not very mobile friendly. Does anyone know a (JS) library to draw "vertical" (top-to-bottom) line charts? 😅
