We’ve been searching for a memory-safe programming language to replace C++ in Ladybird for a while now. We previously explored Swift, but the C++ interop never quite got there, and platform support outside the Apple ecosystem was limited. Rust is a different story. The ecosystem is far more mature for systems programming, and many of our contributors already know the language. Going forward, we are rewriting parts of Ladybird in Rust.

Porting LibJS

I used Claude Code and Codex for the translation. This was human-directed, not autonomous code generation. I decided what to port, in what order, and what the Rust code should look like. It was hundreds of small prompts, steering the agents where things needed to go. After the initial translation, I ran multiple passes of adversarial review, asking different models to analyze the code for mistakes and bad patterns.

When they don't seem to know what definition the person is using for the word after writing an actual and seem confused why some of the quotes are against sexual abuse of 14 year olds, it's sorta hard to take their claims serious. IF DD's point is just people with the sexual preference deserve pity, then I agree. Just in the same way I think people with problems such as gambling or drug addictions should be pitied - it's not something they've chosen and it negatively effects their quality of life. Otoh, I don't think a gambling addict, for example, should be forgiven if they bankrupt their family and cause their children to grow up in poverty unnecessarily. Otoh, it it's a history of defending child abuse, then agreed there should be some discounting going on (but that seems the opposite of the quotes provided).

Either way, isn't the record for ladybird stuff in the git repo or something like that? Doesn't really matter what the source is that brought attention to it if you have the primary source (but people shouldn't be linking to problematic blogs - either link to the primary source or find/make another user-friendly secondary source).
