alias gp="git push"

alias gl="git log --oneline --graph --decorate -20"

# Find stuff fast

function ff() { find . -name "*$1*" 2>/dev/null; }

function killport() { lsof -ti:$1 | xargs kill -9; }

# Open last modified file in nvim

What actually improved:

Keyboard-only workflow is genuinely faster once muscle memory kicks in. I stopped reaching for the mouse in the editor entirely.
Startup time is instant vs VS Code which takes 3-5 seconds on my machine.
SSH editing is miles better - the whole editor is in the terminal, no remote extension jank.
I understand my editor now. VS Code was a black box. Neovim config is just Lua I can read and modify.

What is still annoying:

Plugin ecosystem is powerful but inconsistent. Two plugins solving the same problem will have completely different config styles.
Debugging support still lags. DAP works but the ergonomics are rough compared to VS Code.
Every 3 months something breaks because a plugin changed its API.

Would I go back? No. But I would not recommend it to someone who is not interested in spending time configuring their environment. It is a hobby as much as a tool.

My current setup:

Shell: Zsh with a small set of plugins via zinit (faster startup than Oh My Zsh):

zsh-autosuggestions - suggests completions from history as you type, accept with right arrow
zsh-syntax-highlighting - colours valid commands green, typos red before you run them
fzf integration - fuzzy history search with Ctrl+R is genuinely transformative

Prompt: Starship - cross-shell, fast (written in Rust), shows git branch/status, language versions, exit codes. One config file, works the same in Zsh and Fish.

Tools that replaced standard ones:

eza instead of ls - colours, git status icons, tree view
bat instead of cat - syntax highlighting, line numbers, git diff integration
fd instead of find - faster, saner defaults, respects .gitignore
ripgrep instead of grep - significantly faster, also respects .gitignore
zoxide instead of cd - learns your most visited directories, jump anywhere with z project

Terminal emulator: Ghostty - fast, supports ligatures, good default config.

All config lives in a dotfiles repo and gets installed via a stow-based script. New machine setup takes about 10 minutes.

The usual argument for Vim motions is speed - moving without a mouse, text objects, composable commands. The speed argument is mostly a distraction. The real value is precision - being able to express exactly what you want to do in terms of text structure rather than cursor position.

"Delete everything inside the parentheses" as di( is faster than click, drag, delete - but more importantly, it's less error-prone. You're not approximating with a cursor, you're describing the operation.

Things worth learning, roughly in order:

Basic movement: hjkl, w/b/e (word), 0/$ (line start/end), gg/G (file start/end)
The operator + motion pattern: delete, change, yank + any motion
Text objects: iw (inner word), i"/i' (inside quotes), i(/i{ (inside brackets)
f/F and t/T to jump to characters on the line
. to repeat the last change - this one is secretly the most powerful

How to actually learn them: Install a Vim plugin in your current editor (VSCode Vim, JetBrains IdeaVim) and use it for a week. You'll be slower at first. Push through. By week two it starts to click.

You don't need to switch to Neovim or abandon your IDE. The motions work in almost every editor with a plugin.

What I'm currently running on a Pi 4 + an old mini PC:

Vaultwarden - Bitwarden-compatible password manager. Self-hosted, works with all the Bitwarden clients. The reason I trust it: the server never sees your plaintext passwords (client-side encryption), so even if my server is compromised, credentials are safe.
Immich - Google Photos replacement. Auto-backup from phones, face recognition, timeline view. Has come a long way in the last year.
Jellyfin - Media server. Plex alternative with no account required and no paid tier. Transcoding on a Pi is limited but on anything with a decent iGPU it handles hardware acceleration well.
Miniflux - Minimal RSS reader with a good web UI. I pipe everything I want to read through RSS so I have one place to check instead of visiting 20 sites.
Uptime Kuma - Self-hosted uptime monitoring. Pings my services and notifies via Telegram if something goes down.
Caddy - Reverse proxy. Automatic HTTPS, clean config syntax, much simpler than Nginx for this use case.

How I expose services externally: Cloudflare Tunnel. No open ports on the router, no dynamic DNS headaches, HTTPS handled automatically. The free tier is generous for personal use.

A minimal service file

Code:
[Unit]

Description=My Application

After=network.target

[Service]

Type=simple

User=myapp

WorkingDirectory=/opt/myapp

ExecStart=/opt/myapp/myapp --config /etc/myapp/config.yml

Restart=always

RestartSec=5

[Install]

WantedBy=multi-user.target

Save to /etc/systemd/system/myapp.service

Essential commands

Code:
sudo systemctl daemon-reload          # reload after editing a .service file

sudo systemctl enable myapp            # start on boot

sudo systemctl start myapp             # start now

sudo systemctl restart myapp           # restart

sudo systemctl status myapp            # check status + recent logs

sudo journalctl -u myapp -f            # follow live logs

sudo journalctl -u myapp --since today # logs from today

Useful Service options

Code:
Environment=NODE_ENV=production        # set env vars

EnvironmentFile=/etc/myapp/.env        # load from file

StandardOutput=journal                 # send stdout to journald

StandardError=journal

LimitNOFILE=65535                      # raise file descriptor limit

PrivateTmp=yes                         # isolated /tmp

NoNewPrivileges=yes                    # security hardening

Type values that matter:

simple - process started by ExecStart IS the service
forking - process forks and parent exits (old daemon style)
notify - process signals systemd when ready (more reliable than simple for slow-starting services)

Restart policies:

always - always restart, regardless of exit code
on-failure - restart only on non-zero exit
on-abnormal - restart on signal/timeout/watchdog, not clean exit

The permission model
Every file has three permission sets: owner, group, others. Each set has three bits: read (4), write (2), execute (1).

-rwxr-xr-- 1 alice developers 4096 Jun 22 file.sh

rwx = owner (alice) can read, write, execute
r-x = group (developers) can read and execute, not write
r-- = others can only read

chmod - changing permissions

Code:
chmod 755 file.sh     # rwxr-xr-x (owner all, group+others read+execute)

chmod 644 file.txt     # rw-r--r-- (owner read+write, others read only)

chmod 600 secret.key   # rw------- (owner only, common for SSH keys)

chmod +x script.sh     # add execute for everyone

chmod -w file.txt      # remove write for everyone

chmod -R 755 /var/www  # recursive

chown - changing ownership

Code:
chown alice file.txt           # change owner

chown alice:developers file.txt # change owner and group

chown -R www-data:www-data /var/www  # recursive (common for web servers)

The execute bit on directories
For directories, execute means "can enter" (traverse). A directory with r-- but no x lets you list contents but not access files inside. Usually you want r-x together on directories.

Common permission mistakes:

chmod 777 on web-served files - never. World-writable is a security hole.
Wrong owner on web root (nexusclade instead of www-data) - PHP-FPM can't write uploads
SSH private key too permissive - SSH refuses keys that aren't 600
Forgetting -R on a directory change and wondering why subdirectory access still fails

I'm on Fedora 40 on my main machine. The reason I stay is Fedora's update cadence - new kernel and tooling fast enough that things don't feel stale, but without the chaos of a pure rolling release. The DNF package manager is solid, SELinux enforcement by default is a good habit to be in, and the GNOME experience is genuinely polished here.

On my servers: Debian 12 Bookworm everywhere. No nostalgia, just reliability. Packages are older but that's fine for services running unattended.

What are you on? And bonus question: have you ever distro-hopped extensively and eventually settled somewhere, or are you still looking?]]>
