Package Installation
All language package managers are configured to install into your home directory — nothing goes into system paths. Binaries land in ~/.local/bin, which is already in your PATH.
Python
# Isolated tool install (recommended)
pipx install black
pipx install poetry
# Per-project virtual environment
python3 -m venv .venv
source .venv/bin/activate
pip install requests
# uv (fast pip replacement, also available)
uv pip install requests
/var/cache/poetry and /var/cache/uv to avoid re-downloading packages across users.
Node.js
# npm installs to ~/.local automatically
npm install -g typescript
# pnpm (shared global store at /var/cache/pnpm)
pnpm add -g tsx
Ruby
# gems install to ~/.local/share/gem
gem install rails
# binaries land in ~/.go/bin (already in PATH)
go install golang.org/x/tools/cmd/gopls@latest
Rust
# Cargo is pre-installed
cargo install ripgrep
PHP
# Composer installs to ~/.config/composer
composer global require laravel/installer
Deno
# Already in PATH at ~/.deno/bin
deno install --global npm:typescript
Editors
| Editor | Command | Style |
|---|
| Neovim | nvim | Modal, highly extensible |
| Vim | vim | Modal, ubiquitous |
| Emacs | emacs | Everything editor |
| Nano | nano | Simple, non-modal |
| Micro | micro | Modern, keyboard shortcuts like GUI editors |
| Joe | joe | WordStar-style |
| Mg | mg | Tiny Emacs-compatible |

Terminal Multiplexers
| Tool | Command | Notes |
|---|
| tmux | tmux | Default config pre-installed (see below) |
| screen | screen | Classic |
| byobu | byobu | tmux/screen wrapper with status bar |
| tmate | tmate | tmux + instant terminal sharing |
tmux defaults
Your ~/.tmux.conf comes pre-configured:
- Prefix:
Ctrl-a (instead of the default Ctrl-b)
- Mouse: enabled — click to select panes and windows
- 256 colors: enabled
- Windows: start at index 1
- History: 10,000 lines per pane
Common commands with the Ctrl-a prefix:
Ctrl-a c new window
Ctrl-a n/p next/previous window
Ctrl-a " split horizontally
Ctrl-a % split vertically
Ctrl-a d detach (session keeps running)
tmux attach reattach to your session
