+## Why Nix?

-> look at the [ryan4yin/nix-config/releases](https://github.com/ryan4yin/nix-config/releases) first,
-> **check out to some simpler older versions, such as
-> [i3-kickstarter](https://github.com/ryan4yin/nix-config/tree/i3-kickstarter), which will be much
-> easier to understand**.
 
-This repository is home to the nix code that builds my systems:
+Nix allows for easy to manage, collaborative, reproducible deployments. This means that once something is setup and configured once, it works forever. If someone else shares their configuration, anyone can make use of it.
 
-1. NixOS Desktops: NixOS with home-manager, niri, agenix, etc.
-2. macOS Desktops: nix-darwin with home-manager, share the same home-manager configuration with
-   NixOS Desktops.
-3. NixOS Servers: virtual machines running on Proxmox/KubeVirt, with various services, such as
-   kubernetes, homepage, prometheus, grafana, etc.

-## Why NixOS & Flakes?
-
-Nix allows for easy-to-manage, collaborative, reproducible deployments. This means that once
-something is setup and configured once, it works (almost) forever. If someone else shares their
-configuration, anyone else can just use it (if you really understand what you're copying/referring
-now).
-
-As for Flakes, refer to

-## How to Deploy this Flake?
-
-<!-- prettier-ignore -->
-> :red_circle: **IMPORTANT**: **You should NOT deploy this flake directly on your machine :exclamation:
-> It will not succeed.** This flake contains my hardware configuration(such as
-> [hardware-configuration.nix](hosts/idols-ai/hardware-configuration.nix),
-> [Nvidia Support](https://github.com/ryan4yin/nix-config/blob/v0.1.1/hosts/idols-ai/default.nix#L77-L91),
-> etc.) which is not suitable for your hardware, and requires my private secrets repository
-> [ryan4yin/nix-secrets](https://github.com/ryan4yin/nix-config/tree/main/secrets) to deploy. You
-> may use this repo as a reference to build your own configuration.
-
-For NixOS:
-
-> To deploy this flake from NixOS's official ISO image (purest installation method), please refer to
-> [./nixos-installer/](./nixos-installer/)
 
 ```bash
-# deploy one of the configuration based on the hostname
+sudo nixos-rebuild switch --flake .#nixos-test
-sudo nixos-rebuild switch --flake .#ai-niri
-
-# Deploy the niri nixosConfiguration by hostname match
-just niri
-
-# or we can deploy with details
-just niri debug
 ```
 
-For macOS:
-
-```bash
-# If you are deploying for the first time,
-# 1. install nix & homebrew manually.
-# 2. prepare the deployment environment with essential packages available
-nix-shell -p just nushell
-# 3. comment home-manager's code in lib/macosSystem.nix to speed up the first deployment.
-# 4. comment out the proxy settings in scripts/darwin_set_proxy.py if the proxy is not ready yet.
-
-# Deploy the darwinConfiguration by hostname match
-just local
-
-# deploy with details
-just local debug
-```

-## How to create & managage KubeVirt's Virtual Machine from this flake?
-
-Use `aquamarine` as an example, first build and upload the virtual machine's qcow2 image to the file
-server:
-
-```shell
-just upload-vm aquamarine
-```
-
-Then create the virtual machine by creating a yaml file at
-[ryan4yin/k8s-gitops](https://github.com/ryan4yin/k8s-gitops/tree/main/vms), set the
-`spec.dataVolumeTemplates[0].source.http.url` to the uploaded file's URL, and fluxcd will
-automatically apply the changes, then a virtual machine named `aquamarine` will be created in the
-KubeVirt cluster.
-
-Once the virtual machine `aquamarine` is created, we can deploy updates to it with the following
-commands:
-
-```shell
-just col aquamarine
-just col kubevirt-shoryu
-just col k3s-test-1-master-1
-```
-
-If you're not familiar with remote deployment, please read this tutorial first:

-# My Private PKI / CA
-
-This is my private Private Key Infrastructure (PKI) / Certificate Authority (CA) for my personal
-use. It is used to issue certificates for my own servers and services.
-
-## Current Structure
-
-- **ecc-ca.crt** - ECC CA certificate file
-- **ecc-ca.srl** - CA serial number file for certificate tracking
-- **ecc-csr.conf** - OpenSSL configuration file for certificate signing requests
-- **ecc-server.crt** - Server certificate signed by the ECC CA
-- **gen-certs.sh** - Shell script to generate certificates automatically
-
-## Security Notes
-
-All private keys (`.key` files) are ignored by git and stored in a private secrets repository. The
-public certificates and configuration files are committed to this repository for reference.
-
-## Usage
-
-Run `./gen-certs.sh` to generate new certificates using the ECC CA configuration.
-
-See [../secrets](../secrets/) for the corresponding private key management.

-# Linux Hardening
-
-> Work in progress.
-
-## Goal
-
-- **System Level**: Protect critical files from being accessed by untrusted applications.
-  1. Such as browser cookies, SSH keys, etc.
-- **Per-App Level**: Prevent untrusted applications(such as closed-source apps) from:
-  1. Accessing files they shouldn't.
-     - Such as a malicious application accessing your browser's cookies, SSH Keys, etc.
-  1. Accessing the network when they don't need to.
-  1. Accessing hardware devices they don't need.
-
-## Current Structure
-
-### 1. **System Level**
-
-- **AppArmor** (`apparmor/`): AppArmor profiles and configuration
-- **Kernel & System Hardening** (`profiles/`): System-wide hardening profiles
-
-### 2. **Per-App Level**
-
-- **Nixpak** (`nixpaks/`): Bubblewrap-based sandboxing for applications
-  - Firefox configuration
-  - QQ (Chinese messaging app) configuration
-  - Modular system with reusable components
-- **Firejail** (legacy): SUID-based sandboxing (not used)
-- **Bubblewrap** (`bwraps/`): Direct bubblewrap configurations
-  - WeChat sandboxing configuration
-
-## Current Implementation Status
-
-| Component         | Status    | Notes                          |
-| ----------------- | --------- | ------------------------------ |
-| AppArmor Profiles | 🚧 WIP    | Basic structure in place       |
-| Nixpak Firefox    | ✅ Active | Firefox sandboxing via nixpak  |
-| Nixpak QQ         | ✅ Active | QQ application sandboxing      |
-| Bubblewrap WeChat | ✅ Active | WeChat specific sandboxing     |
-| System Profiles   | 🚧 WIP    | Hardened system configurations |

-## Kernel Hardening
-
-- NixOS Kernel Config:
-  https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs/os-specific/linux/kernel/hardened/config.nix
-
-## System Hardening
-
-- NixOS Profile:
-  https://github.com/NixOS/nixpkgs/blob/nixos-unstable/nixos/modules/profiles/hardened.nix
-- Apparmor: [roddhjav/apparmor.d](https://github.com/roddhjav/apparmor.d)
-  - https://gitlab.com/apparmor/apparmor/-/wikis/Documentation
-  - AppArmor.d is a set of over 1500 AppArmor profiles whose aim is to confine most Linux based
-    applications and processes.
-  - But all the profiles of AppArmor assume a FHS filesystem, which caused all apparmor policies
-    takes no effect on NixOS.
-  - Apparmor on NixOS Roadmap:
-    - https://discourse.nixos.org/t/apparmor-on-nixos-roadmap/57217
-    - https://github.com/LordGrimmauld/aa-alias-manager
-- SELinux: too complex, not recommended for personal use.
-
-## Application Sandboxing
-
-- [Bubblewrap](https://github.com/containers/bubblewrap):
-  [nixpak](https://github.com/nixpak/nixpak), more secure than firejail, but no batteries included.
-  - NixOS's FHSEnv is implemented using bubblewrap by default.
-- [Firejail](https://github.com/netblue30/firejail/tree/master/etc): A SUID security sandbox with
-  hundreds of security profiles for many common applications in the default installation.
-  - https://wiki.nixos.org/wiki/Firejail
-  - Firejail needs SUID to work, which is considered a security risk -
-    [Does firejail improve the security of my system?](https://github.com/netblue30/firejail/discussions/4601)
-- [Systemd/Hardening](https://wiki.nixos.org/wiki/Systemd/Hardening): Systemd also provides some
-  sandboxing features.
-
-## NOTE
-
-**Running untrusted code is never safe, kernel hardening & sandboxing cannot change this**.
-
-If you want to run untrusted code, please use a VM & an isolated network environment, which will
-provide a much higher level of security.

-#
-# A `config.nu` file is used to override default Nushell settings,
-# define (or import) custom commands, or run any other startup tasks.
-# See https://www.nushell.sh/book/configuration.html
-#
-# Nushell sets "sensible defaults" for most configuration settings, so
-# the user's `config.nu` only needs to override these defaults if
-# desired.
-#
-# This file serves as simple "in-shell" documentation for these

-# $env.config
-# -----------
-# The $env.config environment variable is a record containing most Nushell
-# configuration settings. Keep in mind that, as a record, setting it to a
-# new record will remove any keys which aren't in the new record. Nushell
-# will then automatically merge in the internal defaults for missing keys.
-#
-# The same holds true for keys in the $env.config which are also records
-# or lists.
-#
-# For this reason, settings are typically changed by updating the value of
-# a particular key. Merging a new config record is also possible. See the
-# Configuration chapter of the book for more information.

-# Terminal Emulators
-
-I used to spend a lot of time on terminal emulators, to make them match my taste, but now I found
-that it's not worth it, **Zellij can provide a user-friendly and unified user experience for all
-terminal emulators! without any pain**!
-
-Currently, I only use the most basic features of terminal emulators, such as true color, graphics
-protocol, etc. Other features such as tabs, scrollback buffer, select/search/copy, etc, are all
-provided by zellij!
-
-My current terminal emulators are:
-
-1. kitty: My main terminal emulator.
-   1. to select/copy a large mount of text, We should do some tricks via kitty's `scrollback_pager`
-      with neovim, it's really painful: <https://github.com/kovidgoyal/kitty/issues/719>
-2. foot: A fast, lightweight and minimalistic Wayland terminal emulator.
-   1. foot only do the things a terminal emulator should do, no more, no less.
-   1. It's really suitable for tiling window manager or zellij users!
-3. alacritty: A cross-platform, GPU-accelerated terminal emulator.
-   1. alacritty is really fast, I use it as a backup terminal emulator on all my desktops.
-
-## 'xterm-kitty': unknown terminal type when `ssh` into a remote host or `sudo xxx`
-
-> https://sw.kovidgoyal.net/kitty/faq/#i-get-errors-about-the-terminal-being-unknown-or-opening-the-terminal-failing-or-functional-keys-like-arrow-keys-don-t-work
-
-> https://wezfurlong.org/wezterm/config/lua/config/term.html
-
-kitty set `TERM` to `xterm-kitty` by default, and TUI apps like `viu`, `yazi`, `curses` will try to
-search in the host's [terminfo(terminal capability data base)](https://linux.die.net/man/5/terminfo)
-for value of `TERM` to determine the capabilities of the terminal.
-
-But when you `ssh` into a remote host, the remote host is very likely to not have `xterm-kitty` in
-its terminfo, so you will get this error:
-
-```
-'xterm-kitty': unknown terminal type
-```
-
-Or when you `sudo xxx`, `sudo` won't preserve the `TERM` variable, it will be reset to root's
-default `TERM` value, which is `xterm` or `xterm-256color` in most linux distributions, so you will
-get this error:
-
-```
-'xterm-256color': unknown terminal type
-```
-
-or
-
-```
-Error opening terminal: xterm-kitty.
-```
-
-NixOS preserve the `TERMINFO` and `TERMINFO_DIRS` environment variables, for `root` and the `wheel`
-group:
-[nixpkgs/nixos/modules/config/terminfo.nix](https://github.com/NixOS/nixpkgs/blob/nixos-25.11/nixos/modules/config/terminfo.nix#L18)
-
-For nix-darwin, take a look at <https://github.com/LnL7/nix-darwin/wiki/Terminfo-issues>
-
-### Solutions
-
-Simplest solution, it will automatically copy over the terminfo files and also magically enable
-shell integration on the remote machine:
-
-```
-kitten ssh user@host
-```
-
-Or if you do not care about kitty's features(such as true color & graphics protocol), you can simply
-set `TERM` to `xterm-256color`, which is built-in in most linux distributions:
-
-```
-export TERM=xterm-256color
-```
-
-If you need kitty's features, but do not like the magic of `kitten`, you can manually install
-kitty's terminfo on the remote host:
-
-```bash
-# install on ubuntu / debian
-sudo apt-get install kitty-terminfo
-
-# or copy from local machine
-infocmp -a xterm-kitty | ssh myserver tic -x -o \~/.terminfo /dev/stdin
-```

-### LSP - Language Server Protocol
-
-> https://en.wikipedia.org/wiki/Language_Server_Protocol
-
-> https://langserver.org/
-
-The Language Server Protocol (LSP) is an open, JSON-RPC-based protocol for use between source code
-editors or integrated development environments (IDEs) and servers that provide programming
-language-specific features like:
-
-- motions such as go-to-definition, find-references, hover.
-- **code completion**
-- **marking of warnings and errors**
-- **refactoring routines**
-- syntax highlighting (use Tree-sitter instead)
-- code formatting (use a dedicated formatter instead)
-
-The goal of the protocol is to allow programming language support to be implemented and distributed
-independently of any given editor or IDE.
-
-LSP was originally developed for Microsoft Visual Studio Code and is now an open standard. In the
-early 2020s LSP quickly became a "norm" for language intelligence tools providers.
-
-### Tree-sitter
-
-> https://tree-sitter.github.io/tree-sitter/
-
-> https://www.reddit.com/r/neovim/comments/1109wgr/treesitter_vs_lsp_differences_ans_overlap/
-
-Tree-sitter is a parser generator tool and an **incremental parsing** library. It can build a
-concrete syntax tree for a source file and efficiently update the syntax tree as the source file is
-edited.
-
-It is used by many editors and IDEs to provide:
-
-- **syntax highlighting**
-- **indentation**
-- **creating foldable code regions**
-- **Incremental selection**
-- **simple refactoring in a single file**
-  - such as join/split lines, structural editing, cursor motion, etc.
-
-**Treesitter process each file independently**, and it is not aware of the semantics of your code.
-For example, it does not know does a function/variable really exist, or what is the type/return-type
-of a variable. This is where LSP comes in.
-
-The LSP server parses the code much more deeply and it **not only parses a single file but your
-whole project**. So, the LSP server will know whether a function/variable does exist with the same
-type/return-type. If it does not, it will mark it as an error.
-
-**LSP does understand the code semantically, while Treesitter only cares about correct syntax**.
-
-#### LSP vs Tree-sitter
-
-- Tree-sitter: lightweight, fast, but limited knowledge of your code. mainly used for **syntax
-  highlighting, indentation, and folding/refactoring in a single file**.
-- LSP: heavy and slow on large projects, but it has a deep understanding of your code. mainly used
-  for **code completion, refactoring in the projects, errors/warnings, and other semantic-aware
-  features**.
-
-### Formatter vs Linter
-
-Linting is distinct from Formatting because:
-
-1. **formatting** only restructures how code appears.
-   1. `prettier` is a popular formatter.
-1. **linting** analyzes how the code runs and detects errors, it may also suggest improvements such
-   as replace `var` with `let` or `const`.
-
-Formatters and Linters process each file independently, they do not need to know about other files
-in the project.

-# Editors
-
-My editors:
-
-1. Neovim
-2. Helix
-
-And `Zellij` for a smooth and stable terminal experience.
-
-## Tips
-
-1. Many useful keys are already provided by vim, check vim/neovim's docs before you install a new
-   plugin / reinvent the wheel.
-1. After using Emacs/Neovim more skillfully, I strongly recommend that you read the official
-   documentation of Neovim/vim:
-   1. <https://vimhelp.org/>: The official vim documentation.
-   1. <https://neovim.io/doc/user/>: Neovim's official user documentation.
-1. Use Zellij for terminal related operations, and use Neovim/Helix for editing.
-1. As for Emacs, Use its GUI version & terminal emulator `vterm` for terminal related operations.
-1. Two powerful file search & jump tools:
-1. Tree-view plugins are beginner-friendly and intuitive, but they're not very efficient.
-1. **Search by the file path**: Useful when you're familiar with the project structure, especially
-   on a large project.
-1. **Search by the content**: Useful when you're familiar with the code.
-
-## Tutorial
-
-Type `:tutor`(`:Tutor` in Neovim) to learn the basics usage of vim/neovim.
-
-## VIM's Cheetsheet
-
-> Here only record my commonly used keys, to see **a more comprehensive cheetsheet**:
-> <https://vimhelp.org/quickref.txt.html>
-
-Both Emacs-Evil & Neovim are compatible with vim, sothe key-bindings described here are common in
-both Emacs-Evil, Neovim & vim.
-
-### Terminal Related

-
-Text Objects:
-
-- **sentence**: text ending at a '.', '!' or '?' followed by either the end of a line, or by a space
-  or tab.
-- **paragraph**: text ending at a blank line.
-- **section**: text starting with a section header and ending at the start of the next section
-  header (or at the end of the file). - The "`]]`" and "`[[`" commands stop at the '`{`' in the
-  first column. This is useful to find the start of a function in a C/Go/Java/... program.

-
-- Delete the last char of multivle lines: `:normal $x`
-
-  - Execute `$x` on each line
-  - visual mode(v)
-  - `$` moves cursor to the end of line
-  - `x` deletes the character under the cursor
-
-- Delete the last word of multiple lines: `:normal $bD`
-  - Execute `$bD` on each line
-  - visual mode(v)
-  - `$` moves cursor to the end of line
-  - `b` moves cursor to the beginning of the last word
-
-### Search
-
-| Action                                                | Command   |
-| ----------------------------------------------------- | --------- |
-| Search forward/backword for a pattern                 | `/` / `?` |
-| Repeat the last search in the same/opposite direction | `n` / `N` |
-
-### Find and Replace
-
-| Action                           | Command                             |
-| -------------------------------- | ----------------------------------- |
-| Replace in selected area         | `:s/old/new/g`                      |
-| Replace in current line          | Same as above                       |
-| Replace all the lines            | `:% s/old/new/g`                    |
-| Replace all the lines with regex | `:% s@\vhttp://(\w+)@https://\1@gc` |
-
-1. `\v` means means that in the regex pattern after it can be used without backslash
-   escaping(similar to python's raw string).
-2. `\1` means the first matched group in the pattern.
-
-### Replace in the specific lines
-
-| Action                                    | Command                                |

-| Remove the trailing spaces                | `:% s/\s\+$//g`                        |
-
-The postfix(flags) in the above commands:
-
-1. `g` means replace all the matched strings in the current line/file.
-2. `c` means ask for confirmation before replacing.
-3. `i` means ignore case.
-

-# Helix Editor
-
-Neovim is really powerful, and have a very active community. I use it as my main editor, and I'm
-very happy with it. I use it for everything, from writing code to writing this document.
-
-But its configuration is a bit complex, and finding the right plugins, writing configurations, and
-keeping everything up to date is not easy.
-
-That's why I'm interested in Helix, Helix is similar to Neovim, but it's more opinionated, and it's
-batteries included. Whether I'll switch my main editor to Helix or not, it gives me a lot of ideas
-on how to improve my Neovim workflow.
-
-## Tutorial
-
-Use `:tutor` in helix to start the tutorial.
-
-## Differences between Neovim and Helixer
-
-1. Selecting first, then action.
-   1. Helix: delete 2 word: `2w` then `x`. You can always see what you're selecting before you apply
-      the action.
-   2. Neovim: delete 2 word: `d`. then `2w`. No visual feedback before you apply the action.
-1. Helix - Modern builtin features: LSP, tree-sitter, fuzzy finder, multi cursors, surround and
-   more.
-   1. They're all available in Neovim too, but you need to find and use the right plugins manually,
-      which takes time and effort.
-1. Helix is built in Rust from scratch. The result is a much smaller codebase and a modern set of
-   defaults. No VimScript. No Lua.
-   1. Neovim contains a lot of VimScript, and lua is too dynamic, it's hard to debug.
-   1. Personally I'm glad to take a look at a Rust codebase, but not a VimScript/Lua codebase.
-1. Neovim have a very activate plugin ecosystem, and it's easy to find plugins for almost
-   everything.
-   1. Helix is still new, and it even don't have a stable plugin system yet. A PR to add a plugin
-      system is still envolving: <https://github.com/helix-editor/helix/pull/8675>
-1. Neovim has integrated terminal, and it's very powerful. It's quite similar to VSCode's integrated
-   terminal. I use it a lot.
-   1. Helix doesn't have a integrated terminal yet, as it's complicated to implement. Users are
-      recommended to use tmux/Zellij or Wezterm/Kitty to implement this feature instead.
-   1. <https://github.com/helix-editor/helix/issues/1976#issuecomment-1091074719>
-   1. <https://github.com/helix-editor/helix/pull/4649>
-   1. **My Neovim often gets stuck when I switch to
-      [toggleterm.nvim](https://github.com/akinsho/toggleterm.nvim), this Helix issue made me
-      consider to switch from this Neovim plugin to Zellij**.
-1. Helix do not have a tree-view panel, it's recommended to use Yazi/ranger/Broot instead, and open
-   Helix in them.
-   1. a tree-view plugin may be added after the plugin system is stable, but no one knows when it
-      will be.
-   2. and some Helix users stated that they don't need a tree-view plugin, Helix's file picker is
-      useful and good enough.
-1. It seems Helix lacks a global substitution command, you should run it in another window(via wm or
-   Zellij).
-   1. <https://github.com/helix-editor/helix/issues/196>
-   1. Neovim's substitution command allow you to preview the changes before you apply it, and it's
-      very useful. if I switch to Helix, I'll need to find some other tools with similar
-      feature(such as https://github.com/ms-jpq/sad).
-1. Complexity and Maintenance Costs vs Batteries Included:
-   <https://github.com/helix-editor/helix/discussions/6356>
-
-I think Use Helix/Neovim within a terminal file manager(Yazi/ranger/Broot) and Zellij is a good
-idea. It's quite different from the workflow I migrated from VSCode/JetBrains before, I'm very
-interested in it.
-
-In Neovim I can make the workflow similar to VSCode/JetBrains by using some plugins, but Helix
-forces me to get out of my comfort zone, and try something new.

-# Neovim Editor
-
-My Neovim config based on [AstroNvim](https://github.com/AstroNvim/AstroNvim). For more details,
-visit the [AstroNvim website](https://astronvim.com/).
-
-This document outlines neovim's configuration structure and various shortcuts/commands for efficient
-usage.

-## Configuration Structure
-
-| Description                                       | Standard Location                           | My Location                                                               |
-| ------------------------------------------------- | ------------------------------------------- | ------------------------------------------------------------------------- |
-| Neovim's config                                   | `~/.config/nvim`                            | AstroNvim's github repository, referenced as a flake input in this flake. |
-| AstroNvim's user configuration                    | `$XDG_CONFIG_HOME/astronvim/lua/user`       | [./astronvim_user/](./astronvim_user/)                                    |
-| Plugins installation directory (lazy.nvim)        | `~/.local/share/nvim/`                      | The same as standard location, generated and managed by lazy.nvim.        |
-| LSP servers, DAP servers, linters, and formatters | `~/.local/share/nvim/mason/`(by mason.nvim) | [./default.nix](./default.nix), installed by nix.                         |
-
-## Update/Clean Plugins
-
-Note that lazy.nvim will not automatically update plugins, so you need to update them manually.
-
-```bash
-:Lazy update
-```
-
-Remove all unused plugins:
-
-```bash
-:Lazy clean
-```
-
-## Testing
-
-> via `Justfile` located at the root of this repo.
-
-```bash
-# testing
-just nvim-test
-
-# clear test data
-just nvim-clear
-```
