The GPU encoder is several times faster and produces a bigger file at the same quality. Which one to default to, and why.

Encoding saturates the CPU. If your UI shares a thread with it, the recorder stutters exactly when the user is watching.

Gatekeeper decides in the first second whether your app looks legitimate. Signing, notarization, stapling, and what each one actually prevents.

The App Store build is sandboxed and signed by Apple. The direct download is not. What actually differs, and how to keep one source tree.

macOS will not let you prompt twice, and the second attempt opens System Settings instead. Designing the one chance you get.

A seeded company with eight employees and a thousand time entries looked like our best customer for three months. How to seed so that cannot happen.

Verification mails that never arrive are a silent conversion problem. SPF, DKIM and DMARC, and the two traps that cost us a week.

Gateways retry. Networks fail after the work is done. The row that stops a retried callback extending a subscription by two years.

The build succeeds, the file is 74 MB, and it fails on a clean Ubuntu with a dependency error. What the package has to declare.

X11 let any application read the whole display. Wayland does not, and the portal that replaced it changes how your app has to be built.
