COBOL asynchronous signal handling consistency during multi-threaded I/O

While COBOL-2002 provides the EXCEPTION clause for synchronous error handling, the language standard lacks a native mechanism for managing asynchronous timeouts or cancellations. In modern environments where COBOL programs run within multi-threaded containers, graceful cancellation typically relies on mapping OS-level signals like SIGTERM to specific routine

AngularJS $http interceptor retry: scoping automatic retries to idempotent requests only

I'm designing a responseError interceptor (registered via $httpProvider.interceptors) that re-issues failed requests through $http with a bounded retry count and $timeout-based backoff. The goal is transparent retry for transient failures (5xx, timeouts) without ever duplicating a server-side write. The unresolved part is the safety boundary. GET/PUT/DELETE

Stale Entity State during Paginated Query Retrieval in Hibernate L2C

Pagination and Second-Level Cache Interaction When utilizing Hibernate ORM with a Second-Level Cache (L2C), pagination is typically managed via setFirstResult() and setMaxResults() to implement database-level LIMIT/OFFSET clauses. While the query itself identifies the correct entity IDs from the database, the resulting entities are often resolved through the

Limits on OCaml finalizer execution order across runtime versions

OCaml’s language manual specifies that finalizers are executed when the garbage collector reclaims a value, but it does not define the order in which multiple finalizers run. This implementation‑defined behavior can vary between OCaml releases (e.g., 4.12, 4.14, 5.0) and between compilation modes (native code vs. bytecode) or GC settings such as heap size. G

Read the Docs + GitHub: getting failure-only build alerts without the success noise

Goal I have a Read the Docs project connected to a GitHub repository through the native webhook integration, so every push and pull request triggers a documentation build. Email notifications are enabled under Settings → Notifications, but that toggle appears to cover all build outcomes, so successful builds generate the same volume of mail as failures. My g

Karma and Chrome: Configuring retry behavior for browser disconnects

When running tests in Karma with Chrome, a browser may disconnect unexpectedly due to network hiccups or resource constraints. The goal is to determine whether Karma can be tuned to retry a disconnected browser more aggressively or to give up after a configurable number of attempts. Current configuration options include browserDisconnectTimeout , browserDisc

Inconsistent JS–Python FFI behavior between Pyodide and MicroPython runtimes

When testing a PyScript integration that relies on the JS–Python FFI, the objective is to confirm that Python code can import a stub JavaScript module and invoke its functions without using production credentials, while ensuring the test passes regardless of whether the underlying runtime is Pyodide or MicroPython. The two runtimes differ in standard‑library

Affinity-aware allocation replacement in Nomad rolling updates

Migrating a small type = service application across heterogeneous node groups using Nomad's rolling update mechanism requires preserving application-local state without triggering temporary downtime. When dispatch = rolling replaces old allocations, the interaction between reschedule behavior, node affinity constraints, and min_healthy_percentage evaluation

Which measurement reliably isolates Python call overhead in pandas groupby.apply?

Goal and context The goal is to quantify the runtime contribution of groupby.apply in pandas before selecting an alternative implementation. The concern is distinguishing Python function call overhead from pandas internal data handling for realistic workloads.
