ngrx/entity pagination selector: configuring page‑size validation

Goal: ensure that the pagination selector created with createPaginationSelector validates that the supplied page size is a positive integer before slicing the entity map.

Traefik Mesh mTLS Certificate Rotation and Secret Synchronization

Traefik Mesh implements a zero-trust architecture by utilizing a central Certificate Authority (CA) to distribute identities to sidecar proxies via Kubernetes secrets. This mechanism ensures that mutual TLS (mTLS) is enforced for all inter-service communication based on SPIFFE-like identity standards. A critical requirement for maintaining mesh security is t

How widely are SRV records supported?

I've recently learned about DNS supporting SRV records, which identify what port, and what protocol should be used for a given service. For example _http._tcp.example.com SRV should return a port, and an A/AAAA record where the client should be opening a connection which intends to access HTTP service on example.com using TCP . How widely is this supported?

I'm writing a PostCSS plugin that scans a folder of template files and registers them as build inputs. The documented approach is to push { type: 'dir-dependency', dir: ..., glob: ... } objects onto result.messages so the runner (postcss-loader, gulp-postcss, etc.) knows to recompile when anything in that directory changes. What I can't pin down is the bound
