Feathers 5 ESM-first modules create a CommonJS compatibility boundary for existing applications

Feathers 5 ships as ESM-first modules, so applications that previously loaded the framework through require() now encounter a compatibility boundary. The framework package exports resolve through ES module entry points, meaning a CommonJS application attempting to require @feathersjs/feathers fails with ERR_REQUIRE_ESMENT unless the package explicitly provid

Goal We want GatsbyImage or StaticImage to display a blurred placeholder for images that are fetched from remote URLs (e.g. a CMS or CDN) rather than from the local file system.

Inconsistent Key Resolution in YAML 1.2 Merge Key (<<) Implementations

The YAML 1.2 specification allows the merge key << to inherit key-value pairs from one or more source mappings. While the specification ensures that keys explicitly defined in the target mapping override any merged values, it does not provide a definitive rule for precedence when multiple merge sources contain the same key. This ambiguity creates uncer

Does GitHub Actions report artifact upload time as a separate step duration?

Goal Determine whether the built-in timing information shown for each workflow step in the GitHub Actions UI on GitHub.com isolates artifact upload and download duration, or rolls that time into the surrounding step, before deciding where to focus optimization.

Per-shell time zone isolation limits in zsh/datetime

Scripts using the zsh/datetime module often need to format EPOCHSECONDS or parse strings via strftime and strptime in a specific regional time zone. The module documentation ties these operations to the host C library and the process environment, meaning the active zone is inherited from variables such as TZ rather than selected by a zsh option. Because ther
