pfSense's documented build path runs through pfSense-Tools on a FreeBSD host, producing installable ISO and memstick images from source. Repeatability hinges on matching the host FreeBSD release to the pfSense branch being built — for the current CE 2.7.x line the docs point at a specific FreeBSD 14.x release, though the exact pairing should be confirmed aga
Goal: Ensure that subscribed content library synchronization occurs only during defined maintenance windows and does not exceed a specified bandwidth limit to protect production traffic. Currently, vSphere Content Library subscriptions synchronize on a fixed 60‑minute interval with no native scheduler or bandwidth throttling controls, and the API does not ex
Goal I want to run Emacs on a small VPS where it is only used a few times per day for short editing sessions. The aim is to keep both startup latency and resident memory low without giving up my existing init configuration, which loads a moderate set of packages. Constraints and uncertainty Two documented approaches seem relevant: running Emacs as a persiste
NixOS Module System When running nixos-rebuild switch with a missing or mis‑named entry in the imports list of /etc/nixos/configuration.nix , the NixOS module system aborts the build and reports a generic attribute‑missing exception. The evaluator does not automatically indicate which file path caused the lookup failure, leaving users to trace the problem ma
UNABLE_TO_LOCK_ROW and retried writes We have an Apex integration where inbound middleware retries a request whenever the first attempt fails partway through — for example after a row lock contention error such as UNABLE_TO_LOCK_ROW, or when our own Queueable retry logic re-enqueues a job. The Apex side currently performs a plain insert, so every retry after
Context A project requires a recent version of a CLI tool that is available in a third‑party tap but not yet in Homebrew core. The CI runners have limited CPU and memory, so building from source adds several minutes to each pipeline run. Core currently offers an older version that has a prebuilt bottle, while the tap provides the desired version but only as
DNS Resolution Timing in Packer HCL2 Templates When configuring Packer templates with multiple network interfaces or custom DNS settings, there is an unresolved question about when DNS resolution occurs relative to template validation and builder initialization. The HCL2 syntax allows defining custom DNS servers through builder configurations like dns_server
Facebook Login Token Refresh During User Password Changes Facebook Login for Websites issues short-lived access tokens (typically 1-2 hours) with refresh token mechanisms for extended sessions. The OAuth 2.0 implementation supports automatic token refresh when applications properly implement the refresh flow using the JavaScript SDK or server-side OAuth endp
Performance Measurement Constraint The goal is to establish a reliable baseline for latency when validating system sanity under defined load conditions. Uncertainty and Scope The constraint is maintaining a P95 latency below 50ms during a sustained 100 concurrent connection test using the documented sanity check feature.
