People in government agencies, defence and aerospace companies write code in airgapped environments every day.
Essentials like version control, CI/CD and artifact repositories are readily available, as they always have been.
The problem you'll face with LLM assists is they require very substantial hardware. I don't know how well that's going to fit your laptop-in-the-middle-of-nowhere use case, but there are projects floating around.

Notably absent are all of the remote debugging extensions and Copilot. This would be a deal-breaker for many.

> Following DeepSeek's disruption of the LLM landscape, the Eclipse Foundation bets that collaborative, open source AI tooling can outmaneuver billion-dollar proprietary competitors.
Maybe! Eclipse Theia was a pretty great web capable editor when I gave it a spin in ~2018.
The main thing I've wanted has been collaboration. Looks like there's been some real progress on that front, as of this past fall. Definitely like the idea of multiparty IDEs, and if AI can come play in that mix that will would be interesting! Feels like AI has been a pretty solo you & the machine experience.

Project mention: How do you manage remote dev workstations in the cloud? | news.ycombinator.com | 2024-12-27Gitpod (https://www.gitpod.io) is a great option here. It aims to remove the ops burden, provide a great developer experience and give you tools to manage your spend (eg automatic timeouts, suspend/resume, standardized creation of environments).

AstroNvim
AstroNvim is an aesthetic and feature-rich neovim config that is extensible and easy to use with a great set of plugins
You can definitely put all of your configuration into a single file for AstroNvim if you want.
In the docs it shows the minimal configuration to get AstroNvim running which is <10 lines in your ~/.config/init.lua file and then anything else you can just drop in that same file if you want. (https://github.com/AstroNvim/AstroNvim?tab=readme-ov-file#mi...)
Here is a user on GitHub that has a single file AstroNvim configuration: https://github.com/20k-ultra/dotfiles/blob/master/nvim/init....
