Project mention: Show HN: Pdfwithlove – PDF tools that run 100% locally (no uploads, no back end) | news.ycombinator.com | 2026-01-18
It's possible to run WebAssembly programs from the command line (without any GUI) using WASI (see e.g. https://github.com/WebAssembly/WASI). Thus if the user downloads pdfconverter.wasi , and the user already has e.g. wasmtime installed, they can run `wasmtime pdfconverter.wasi input.pdf output.pdf` from the command line (see https://github.com/bytecodealliance/wasmtime/blob/main/docs/... for details).
In addition to the web site, the Electron app and the Chrome extension, you may want to distribute a command-line version of your tools as WASI-style .wasm program files. If you do so, I would exclusively use the them this way, from the command line.

Project mention: Lenovo's New ThinkPads Score 10/10 for Repairability | news.ycombinator.com | 2026-03-03
There's actually a compatibility listing and the hacks required to make them work! https://github.com/NixOS/nixos-hardware
In the case of my ThinkPad, you can see there is literally no extra work required: https://github.com/NixOS/nixos-hardware/blob/master/lenovo/t...
Still, doesn't mean you shouldn't look into other brands, obviously. Take a look at that repo to see if there's obvious compatibility stuff.
