Project mention: Brush (Bo(u)rn(e) RUsty SHell) a POSIX and Bash-Compatible Shell in Rust | news.ycombinator.com | 2025-05-06
"can" is doing some heavy lifting there, especially based on my experience with VSCodium (which by definition is forced to work within Microsoft's opinion of build systems)
Anyway, uh-huh:

SkiaSharp
SkiaSharp is a cross-platform 2D graphics API for .NET platforms based on Google's Skia Graphics Library. It provides a comprehensive 2D API that can be used across mobile, server and desktop models to render images.
If you've read any of the other articles this month, you've likely seen SkiaSharp mentioned already. While drawing and text aren't usually a combination I consider, I figured it was worth a shot. I asked Copilot first for an analysis of what the improvement might be along with a plan.

electrino
Desktop runtime for apps built on web technologies, using the system's own web browser engine
Project mention: Electrobun: Cross-platform desktop applications written in TypeScript | news.ycombinator.com | 2024-11-20So is it a yet another webview-based framework like NeutralinoJS (https://neutralino.js.org), Electrino (https://github.com/pojala/electrino) or DeskGap (https://deskgap.com)? What's their advantage apart from using Bun instead of Node?
For relly lightweight cross-platform desktop apps better use a non-webview-based native framework like Qt, GTK, wxWidgets or even recently released FLTK 1.4.
