The Reflog: Git's Safety Net

"I lost my commits" is almost never true. A bad reset, a botched rebase, a deleted branch — the commits are usually still there, sitting unreachable in the object store, waiting out their grace period before garbage collection. The reflog is the log of everywhere your refs have been, and it's the tool that turns "I destroyed my work" into a thirty-second recovery. Knowing it exists changes how fearlessly you can use Git.

The Index: Git's Staging Area

Every Git user meets the staging area on day one — `git add` puts things there, `git commit` takes them out — but almost nobody knows what it actually is. The index is a real file, a binary snapshot-in-progress that sits between your working directory and the object store. Understanding it turns `add`, `reset`, and the difference between "staged" and "modified" from memorized rules into a picture you can see.

The Git Object Model

Git looks like a tool for tracking changes, but underneath it is something simpler and stranger: a small content-addressed key-value store. Four object types — blob, tree, commit, tag — are all it keeps, each named by the hash of its own bytes. Once you see that everything else (branches, history, staging) is a thin layer over these four objects, Git stops being a bag of memorized commands and becomes a system you can reason about.

Underneath the commands, Git is a small content-addressed key-value store built on four object types — blob, tree, commit, tag — each named by the hash of its own bytes. Seeing that everything else is a thin layer over these objects turns Git from memorized incantations into a system you can reason about.

Getting Started: Cargo and the Toolchain

Rust's tooling is one of its quiet superpowers — a single tool, Cargo, handles building, dependencies, testing, and more, and it's good enough that Rust developers rarely think about build systems at all. Before the language's hard ideas, meet the tooling that makes working in Rust pleasant.

What Claude Code Is

An agentic coding tool that lives in your terminal, reads and edits your real codebase, runs commands, and works through multi-step tasks — not an autocomplete, but a collaborator you delegate to.

The opener to a Claude Code series: what an agentic, terminal-native coding tool actually is — it takes a goal and executes multi-step work on your real codebase, with permissions keeping you in control — and the mental model that makes it click.
