I've used #Docker for 10+ years and I thought I knew how image layers work. Then I asked one innocent question: if layers are just tar archives stacked on top of each other, how can a layer DELETE a file from a previous one? 🧵 loige.co/hidden-desig...

The hidden design compromises of Docker layers

How Docker and OCI image layers represent filesystem changes, why deleting a file needs special whiteout entries, and what happens if you create a file called .wh.foo.

Confession: my fingers still type `npm i axios` on autopilot from time to time 😅 ...And yet… Node.js has shipped a built-in `fetch()` since v18 (2022)! Still, I keep running into the same questions: - Should we use it? - When is it a good fit? - How do we avoid the usual footguns?

Cartoon illustration in flat colors: a smiling developer in a blue hoodie points upward while holding a green “Node.js FETCH GUIDE” book. Above him, speech bubbles read “npm axios”, “http/https”, and “fetch()” with a question mark. On the right, a cool turtle wearing sunglasses rides a rocket labeled “V8”; a checklist and stopwatch sit on the desk against a soft, patterned sky background.
