SystemTechniques · 17Primitives · 58 mobile-ci Deterministic simulation testingdistributed · medium: Run the whole system in one thread under a seeded scheduler with simulated network, disk and clock, so every failure replays from its seed.›Durable job queuedistributed · medium: Persisted tasks that workers lease for a visibility timeout, ack on success and retry with backoff; at-least-once execution that survives worker and queue crashes.›Primary-backup replicationdistributed · medium: One node orders all writes and ships them to standbys; the acknowledgement rule (none, one, all) sets what a crash loses, and an external arbiter decides who takes over.›Code signingsecurity · medium: Signing binaries/apps with certificate chains, entitlements, timestamping and notarizationCoverage-guided fuzzingsecurity · medium: Mutate inputs, run an instrumented target, and keep any input that reaches a new code edge; feedback turns blind guessing into incremental search.›Workload identity (SPIFFE-style)security · medium: A local agent works out which workload is calling, then hands it a short-lived signed identity that it renews automatically; no secret is shipped in advance.›Point-in-time recoverystorage · medium: Periodic base backups plus a continuously archived change log let you rebuild the state as of any instant, then branch from there.›X509 certificatessecurity · low: Certificate chains, path validation, SANs, revocation and short-lived issuanceJSON Web Token (JWT)security · low: A signed, URL-safe token carrying claims; the verifier's job is the checklist (pinned algorithm, key by kid, exp, aud, iss), not the format.›Mutual TLSsecurity · low: TLS where the client also proves a certificate key, so every connection carries a verified, rotatable machine identity.›Secrets managementsecurity · low: Keep keys and passwords out of code and logs, give workloads short-lived identity instead of static keys, and make rotation routine.›Semver range matchingcompilers · low: Semantic version parsing, ordering and range matchingHdr histogramdata-structures · low: Log-linear bucketed histograms with bounded relative error for latency percentilesHardware virtualization kvmhardware-os · low: VT-x/AMD-V via KVM: vCPU run loop, VM exits, MMIO emulationProcess supervisionhardware-os · low: A parent process starts services, reaps their exits and restarts them under a delay and burst-limit policy, then stops them with SIGTERM before SIGKILL.›Resumable uploadsnetworking · low: Open an upload session, send the body in offset-addressed chunks, and after any failure ask the server how much it committed and continue from there.›Content-addressed storagestorage · low: Store each blob under the hash of its bytes: immutable, deduplicated by construction, self-verifying on every read, and composable into Merkle trees.›Graceful drainingsystems · low: On a termination signal, stop taking new work, finish in-flight work until a deadline, tell clients to reconnect elsewhere, then exit; clients resume from a token.›Cooperative schedulingconcurrency · low: Green threads/coroutines yielding at await points on a user-space schedulerRecord replaydistributed · low: Record every nondeterministic input (time, randomness, I/O, model and tool outputs, per-tick player input) and re-execute deterministically for debugging, replays and state rebuildPRNGs (PCG, xoshiro)numerics · low: Small, fast, statistically strong non-cryptographic generators: PCG32 and xoshiro256**, with seeding, parallel streams and unbiased ranges.›Dead-letter queuedistributed · low: A side queue for messages that keep failing: after N delivery attempts or a permanent error, park them with the reason so the main queue keeps moving.›Leasesdistributed · low: A lock that expires on its own: bounded-time ownership that survives crashes and partitions, given bounded clock drift and fencing tokens on writes.›+ 10 more techniques+ 42 more primitives
