Limits: Space_Overhead Tuning for Low‑Traffic OCaml 5 Services

The goal is to lower the cloud bill for a native‑compiled OCaml service that receives only a handful of requests per hour. The primary knob is Gc.set ’s space_overhead parameter, which controls how aggressively the major GC runs: a higher value means fewer collections but a larger heap, while a lower value forces more frequent collections and a smaller heap.

Limits of ROS2 Message Schema Evolution: Unresolved Rollback Decision

Goal Determine how ROS2 can guarantee safe rollback after a message schema change without redeploying nodes. Current Constraints ROS message definitions (.msg, .srv, .action) are static; any change requires recompilation of all dependent packages. ROS2 leverages DDS, which supports limited schema evolution (e.g., adding optional fields), but the ROS2 build s

Per‑Client Time‑Zone Conversion for Dovecot IMAP Dates?

Background Dovecot parses the RFC‑5322 Date: header of each message and stores the resulting timestamp internally in UTC. The original header is preserved unchanged. When a client issues an IMAP SEARCH SINCE/BEFORE/ON command, the server interprets the date arguments relative to its configured local time zone. This can lead to off‑by‑one‑day results for clie

Goal Choose between WooCommerce Cart Fragments and a full page reload for cart updates after an add-to-cart action, prioritizing keyboard and screen-reader navigation. Constraint Cart Fragments update totals and mini-cart contents asynchronously, but focus often shifts to the page header, leaving screen-reader users without confirmation of the change. A full

Which Image Source Does GitHub Codespaces Prioritize When a Floating Base Image Tag Changes?

Repeatable Development Environments with Codespaces When a repository commits a devcontainer.json that uses a floating base-image tag (e.g., ubuntu:latest ), the same file can resolve to different image layers over time. A Codespace prebuild captures the resolved image at the moment the prebuild is created, potentially storing an older digest that no longer

cairo: surface write-to-png fails - cairo_save does not roll back surface schema changes

Goal Decide whether cairo should automatically revert surface-level schema changes after cairo_save/restore, or leave surface state management to the caller. Constraints In cairo 1.18 and later, cairo_save and cairo_restore protect the graphics state but do not undo surface format or device-surface modifications. A subsequent cairo_surface_write_to_png may t
