Git diff pager praised for readable character-level highlighting and straightforward package installation.
Source discussion: Show HN: OmniDiff – Opensource, super fast, content aware Git difftool, in Rust
“Delta has a really nice way to show diffs with its diff-so-fancy mode, it's more similar to GitHub's UI where not only the line is colored up differently but there's a different shade of color to highlight the characters.”

Small WebGL 2 library whose demos impressed a commenter with 120-FPS phone performance.
Source discussion: Show HN: I rebuilt my old canvas 3D library as a small WebGL 2 library – phoria2
“This is super cool, and I loved seeing the FPS stay locked at 120 on my phone. I didn't see this on the website, but do you have any docs that detail how your library compares to other popular options such as Three, Babylon, etc? Definitely giving this a try today. One thing I noticed is that the "hover" functionality in most of the demos doesn't behave well on mobile.”

Source discussion: Lenovo's 'encrypted' fingerprint USB is just an unencrypted SD card in a case
