Also tried KDE connect a few years back, but didn't like the idea of giving a buggy phone access to shoulder-surf root accounts. Transferring stuff out of a VM with a local samba instance also works, but samba should also be containerized.

Project mention: 'Fuck you, Bambu': How one private message could change the face of 3D printing | news.ycombinator.com | 2026-05-24
Depends on your budget but I am extremely happy with Snapmaker U1. I print with ASA, PETG, and TPU. It prints PLA very well by default. It runs klipper, gives you full SSH with root. I installed paxx12's extended firmware using a USB flash drive - https://github.com/paxx12-snapmaker-u1/SnapmakerU1-Extended-... and have been able to get 20+ fps camera feed.

Project mention: 4x faster network file sync with rclone (vs rsync) (2025) | news.ycombinator.com | 2026-02-02
SSH was never really meant to be a high performance data transfer tool, and it shows. For example, it has a hardcoded maximum receive buffer of 2MiB (separate from the TCP one), which drastically limits transfer speed over high BDP links. The encryption can also be a bottleneck. hpn-ssh [1] aims to solve this issue but I'm not so sure about running an ssh fork on important systems.

I found an open source homebrew 3DS application that can connect to a remote host via SSH and run Claude Code on it. I tested it on my own 3DS,the experience was greatβit even supports voice input.
With the 3DS's dual screens, analog stick, multiple buttons (mapped to Ctrl, Alt, etc.), and voice input, using Claude Code is very smooth. I also ported the Tailscale library to the 3DS and used it in my local build, so I can use my 3DS to control my computer and run Claude Code/Codex anytime I'm in a network environment.
The repository link is: https://github.com/Fishason/DSSH
3DS is so cool.
