JetStream pull-consumer pagination after a 2.9 to 2.10 upgrade: ephemeral or durable consumers for bounded reads?

Goal We are moving a NATS JetStream deployment from server 2.9.x to 2.10.x and need to settle on a pagination design for reading a large stream (millions of messages) from a service that answers "give me the next page of history" requests. NATS core has no query or offset/limit semantics, so the plan is to use pull consumer Fetch calls with bounded batch siz

Artix user-installed service does not start automatically under runit or OpenRC

Service does not activate automatically on Artix Linux The goal is to diagnose why a user-installed service is not started automatically after installation on an Artix Linux system that uses runit or OpenRC as PID 1, without assuming a single default init system. Enablement differs by init system: runit supervises services through symlinks under /etc/service

PuTTY SSH keepalive and silent-peer timeout need diagnosis

On Windows, PuTTY’s documented Connection settings expose SSH application keepalives and TCP keepalive separately. The goal is to determine whether either control can enforce a maximum period without user data before PuTTY closes a session whose peer has disappeared without FIN or RST. The SSH keepalive interval is not a connection timeout: it sends global r

DNF metadata_expire Configuration and Automated Cache Refresh Boundaries

Cache Expiration Behavior DNF caches repository metadata under /var/cache/dnf with a configurable metadata_expire value that defaults to six hours for new metadata and thirty days for previously successful metadata. The setting controls when an automatic refresh is triggered, yet the exact interaction between the expire window, explicit dnf makecache calls,

Next.js Data Cache on multi-instance self-hosting: propagating revalidateTag across servers

I'm planning a self-hosted Next.js App Router deployment behind a load balancer with multiple Node.js instances, and the Data Cache invalidation boundary is unclear to me. My understanding is that fetch() responses with next: { revalidate: N } or tags are stored in a per-instance, filesystem-based cache. If a Server Action calls revalidateTag('products') , i

pnpm lockfile schema change v8 to v9 rollback safety

Goal: deterministic rollback after lockfile schema transition pnpm uses a content‑addressable store that keeps each package version once in the global store, symlinking it into node_modules . The lockfile carries a lockfileVersion field that changed from 6.0 (pnpm 8) to 7.0 (pnpm 9) to support new features. When a project is checked out with a lockfile gener

UNABLE_TO_VERIFY_LEAF_SIGNATURE during pnpm tarball downloads with strict-ssl disabled and custom ca configured

Corporate networks that intercept TLS often require pnpm to trust a custom certificate authority while also disabling strict SSL validation. In these environments, pnpm install can fail with UNABLE_TO_VERIFY_LEAF_SIGNATURE even after both strict-ssl=false and a custom ca or cafile are configured. The uncertainty is that pnpm's fetcher appears to apply these

Inconsistent Log Verbosity Across OS When Capturing Native Crash Dumps in JetBrains IDEs

Goal When a deployment fails, the JetBrains IDE should provide a consistent, detailed log that captures native crash dumps regardless of the operating system.

Does GCC's -Wshadow warn on lambda captures that shadow outer variables?

Goal The goal is to determine whether the -Wshadow option should emit a warning when a C++ lambda capture introduces a name that hides an outer variable. Constraints The GCC manual states that -Wshadow applies only to C, yet GCC 10 produces a warning for such lambda captures while GCC 12 does not, and the bug tracker lists this discrepancy as an open issue.
