One image for all screen resolutions and different devices is not enough. An image per pixel is too much - so how can someone automatically choose the optimal responsive image sizes?
Responsive websites, even the most modern ones, often struggle with selecting image resolutions that best match the various user devices.

For the 6 months or so I’ve been quietly porting tmux from C to Rust. I’ve recently reached a big milestone: the code base is now 100% (unsafe) Rust. I’d like to share the process of porting the original codebase from ~67,000 lines of C code to ~81,000 lines of Rust (excluding comments and empty lines). You might be asking: why did you rewrite tmux in Rust? And yeah, I don’t really have a good reason. It’s a hobby project. Like gardening, but with more segfaults.
