A hands-on walkthrough of replacing Tailscale with Headscale, the open-source alternative. Covers WireGuard mesh fundamentals, full Headscale installation, ACL policies, subnet routing, and exit nodes — all self-hosted with no proprietary control server.
Dreams of Code builds a minimal but powerful Zsh configuration from scratch — no frameworks, no plugin managers. Covers Starship prompt, syntax highlighting, autosuggestions, fzf integration, and a clean dotfiles structure you fully control.
Git worktrees are 15x more popular than a year ago — and AI agents are the reason. This walkthrough covers the fundamentals, the multi-agent workflow, and how tools like Claude Code use worktrees to run parallel agents without merge conflicts.
The Rad Lectures builds a NeoVim 0.12 config from scratch in under 1,000 lines with a strict 10-plugin limit. Built-in vim.pack package manager, custom statusline, Treesitter (new API), LSP via lspconfig + mason, lint/format via efm-langserver, and blink.cmp + luasnip completion — in the age of AI slop, editing efficiency still matters.
A 19-minute walkthrough takes Neovim from an empty directory to Go LSP, debugger, fuzzy finder and Copilot, and argues the case with startup measurements rather than assertions: seven Extras added, startup unchanged at 27ms. The method holds up entirely. The specifics do not - checked against current source, LazyVim has shipped 33 releases and two major versions since, snacks replaced both fzf-lua and neo-tree as defaults, completion moved to blink, and Neovim 0.11.2 is now required. Includes a full then-versus-now table.
A ten-minute tour of the Vim commands worth knowing, from :q to macros, with a genuinely well-chosen progression: search, change, repeat, registers, automate. Every command is listed here with what it does and why you would reach for it - and every one was executed against a real Neovim 0.12.1 to confirm the behaviour described, in headless sessions with -u NONE so no personal config could alter the result. Twenty-eight behaved exactly as described. Two did not. The video says numbered registers fill as a rolling yank history; running three consecutive yanks leaves registers 1-3 empty, because 0 is the last yank and 1-9 are the delete history. And it frames the star versus plus clipboard register as a macOS versus Linux difference, when plus is CLIPBOARD everywhere and star is X11 PRIMARY - the video's own macOS demo uses plus. Also missing entirely from a beginner video full of destructive commands: undo.
