Fifteen minutes, no API keys, nothing to pay for, and a real mp4 at the end of it. The cheapest way to find out whether keryx does what you think.

Twenty minutes from a folder of frames to an album-ready export, with nothing written over an original. Also: the install method that will cost you an evening if you pick the obvious one.

A change that ships without a version bump reaches nobody, and nothing tells you. Ten minutes in a throwaway directory to see it happen, and then catch it.

A backup is only real once you have tested the restore. A self-hosting backup guide that deliberately refuses to bless a single tool.

Setting up an AWS billing alarm before you need one, with a KMS gotcha in the middle that stops the alert ever reaching you.

Choosing a CLI library in Go and Rust. Go is a ladder you climb from the standard library; Rust asks a different question much earlier.

Rotate a release signing key and recover from a bad one without locking users out. Why asymmetric KMS keys have no auto-rotate button.

Make a tagged release sign itself: record the KMS key and regenerate GoReleaser config with a signs block that calls gtb sign directly.

Embed the trust anchor in your binary and require signature verification on update, without bricking anyone already running an old build.

Mint an OpenPGP public key from a KMS-held private key you cannot hold, and publish it somewhere the release platform cannot reach.
