Before you adopt an AI tool, check how you would leave it

Most AI features get evaluated on what they do on day one. The harder question is what you can take with you if you ever need to switch.

A recent BytePreview guide on data portability draws a useful line between three things: the data you put in, the outputs the tool generates, and whatever belongs to the provider or depends on its infrastructure. An "Export" button doesn't tell you which of those you get back, or whether the result is usable anywhere else.

Points worth turning into a checklist:

Read the exclusions, not just the promise. Microsoft's documentation, for example, lists exportable customer data (text, audio, image and video files, database content) but leaves out resource configuration details and protected proprietary data.
Retention depends on the data type. In Amazon Location Service, device positions are kept for 30 days and then deleted automatically, while geofence geometries you upload must be deleted explicitly.
An API is not an exit plan. Check which operations and data it really exposes. Being able to call a feature doesn't give you its underlying model.
Format, content and procedure are separate checks. Does the export keep the fields and relationships you need, and can you repeat it at volume?

The guide suggests a simple matrix (export, format, retention, deletion, interfaces), writing down open questions instead of filling gaps with assumptions, and saving the version and date of every document you review. Anything critical that isn't documented belongs in the contract.

How to verify that a security update actually fixed what it claimed

Security updates are easy to install and hard to trust blindly. A changelog line that says "fixed CVE-…" does not prove the patch landed on your systems, or that the vulnerable code path is gone.

A practical checklist

Identify the claim — which CVE, package, or component is supposed to change.
Confirm the binary/package version after the update (not just that the updater ran).
Reproduce or probe the old failure mode in a safe environment when possible (version banner, feature flag, test that previously failed).
Watch for regressions in the same release notes — security fixes sometimes tighten defaults.
