I try not to do ranty threads anymore, but man, this Valve GDC graph has just rubbed me up unbelievably badly

This was presented as a good thing - "more games are finding success!" -- when actually the data has just been presented in a tricksy way to make it look like everything is fine

Duper's new superpowers! | Duper The format that's super!

With Temporal values, support for more languages, extra tools for logging, a fully-functioning LSP, and more, it's certainly not pulling any punches!

Duper's new superpowers!

It's been over a month since Duper's public announcement, and now, it's more super than ever! I've taken all the feedback from the initial post and worked on it.

It's at a good enough point that I felt like sharing it, but there's still plenty I wanna work on! Namely, I want to add (real) #nodejs support, make a proper LSP with auto-formatting, and get it out there before I start thinking about stabilization.

Built in #rust, with bindings for #python and #wasm, as well as syntax highlighting in VSCode. I made it for those like me who hand-edit JSONs and want a breath of fresh air.
