nixos VS ExpansionBay

This mostly minimal example seems legit, but I can't get it working.

https://github.com/Lillecarl/nixos/blob/master/shitbox/disko.nix https://github.com/Lillecarl/nixos/blob/master/shitbox/default.nix#L10

https://github.com/Lillecarl/nixos/blob/master/shitbox/disko... this is my declarative partitioning scheme, I use mdraid, LUKS, LVM and btrfs. I also mirror my bootloader so if one drive dies I can still boot :)

Hardware raid is legacy :)

https://github.com/Lillecarl/nixos here's my configuration. I'm moving a lot of packages from my system config to my home config instead still. There's also something called devshells you can use with flakes, that'll give you packages in a one time disposable shell, which is quite great.

Zellij instead of tmux (not necessarily better, but it's easier to use)

Xonsh instead of bash (because you already know Python, why learn a new horrible language?)

bat instead of cat (syntax highlights and other nice things)

exa instead of ls (just nicer)

neovim instead of vim (just better)

helix instead of neovim (just tested it, seems promising though)

nix instead of your normal package manager (it works on Mac, and essentially every Linux dist. And it's got superpowers with devshells and home-manager to bring your configuration with you everywhere)

rmtrash instead of rm (because you haven't configured btrfs snapshots yet)

starship instead of your current prompt (is fast and displays a lot of useful information in a compact way, very customizable)

mcfly instead of your current ctrl+r (search history in a nice ncurses tui)

dogdns instead of dig (nicer colors, doesn't display useless information)

amp, kakoune (more alternative text editors)

ripgrep instead of grep (it's just better yo)

htop instead of top (displays stuff nicer)

gitui/lazygit instead of git cli (at least for staging, nice with file, hunk and line staging when you have ADHD)

gron + ripgrep instead of jq when searching through JSON in the shell (so much easier)

keychain instead of ssh-agent (better cli imo)

Wrote this on the train with my phone by checking https://github.com/Lillecarl/nixos/blob/master/common/defaul... for which packages I have installed myself :)

This is my pipewire config, does the job perfectly for me, tracking unstable.

There is potential for an external battery. It doesn't exist yet, but the connector supports power going from the expansion bay to the laptop[0], so someone could build a battery module or potentially even a hot-swappable adapter to use a removable battery for a more common laptop.

[0] See pins 41-51 on https://github.com/FrameworkComputer/ExpansionBay/tree/main/...

We've designed the Expansion Bay module system to be able to handle power bi-directionally. One of the main reasons for this was to enable secondary batteries. This specific module isn't something we've shared any plans around, but it's something that either we or a third party would be able to build.

https://github.com/FrameworkComputer/ExpansionBay

According to the spec doc on their github, the gpu rail, while on AC, caps out at 10.5A @ 20V (allthoug that is the peak burst cueewnt, max sustained is not mentioned but is likely slightly lower), so we will likely eventually see some higher wattsge GPUs over time, especially give. The headroom between the 175W max burst draws we see from top end laptop chips today and a 210w limit. Thermals will liley be more of a concern than power at that point tho.(https://github.com/FrameworkComputer/ExpansionBay/blob/main/Electrical/README.md)

I don't think anybody outside Framework knows for sure yet (maybe not even internally) but my impression from what they've shared so far is that the expansion bays are intended to be very easily swappable (external, a click & push kind of thing) but probably not hot-swappable while the machine is powered on.

They do have some initial specs at https://github.com/FrameworkComputer/ExpansionBay that somebody more knowledgeable than me might be able to glean some practical info from.

According to the Framework Github (https://github.com/FrameworkComputer/ExpansionBay/tree/main/Electrical) expansion bay modules (e.g. second battery or GPU) are connected via two 74-pin connectors.

Framework is doing brilliant work. They create reusable computer formats that anyone can hack against. Strongly considering a Framework 13 as my next computer.

- Expansion bay: https://github.com/FrameworkComputer/ExpansionBay

I know it's niche but it would be cool if they could attach an expanded battery pack into its expansion module.

Mybad, according to https://github.com/FrameworkComputer/ExpansionBay/tree/Main/Electrical ,the maximum wattage with the 'high power adapter' is 20v*10.5A which suggests 210w max for the entire device.
