SystemTechniques · 19Primitives · 77 fund-admin Template enginescompilers · medium: Compile templates with loops, partials and auto-escaping into render functionsDAG workflow executiondistributed · medium: Run a graph of dependent tasks by releasing each one when its inputs are done, longest chain first, and skip any task whose input hashes are unchanged.›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.›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.›Cost allocation modelsfinance · medium: Split shared resource costs across tenants by requests, usage or proportional shareTax lot accountingfinance · medium: Per-lot cost basis (FIFO, specific ID), wash-sale rules and tax-loss harvestingCoverage-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.›Largest remainder roundingfinance · low: Splitting an amount into parts that sum exactly (largest remainder / Hamilton) for allocations, splits and prorationsCorporate-action adjustmentfinance · low: Keep raw bars plus a tiny table of cumulative backward factors, built by one reverse scan over events and applied at read time, versioned by as-of date.›Money representationfinance · low: Store money as integer minor units with an explicit currency exponent, compute in wider integers, and round once with a named rounding mode.›Hdr histogramdata-structures · low: Log-linear bucketed histograms with bounded relative error for latency percentilesPriority waterfall allocationeconomics · low: Applying incoming payments to fees, interest and principal in a defined priority orderCurrency cross rate triangulationfinance · low: Deriving cross rates through a base currency with correct precision, inversion and spreadsDay count conventionsfinance · low: ACT/360, ACT/365, 30/360, ACT/ACT accrual fractions for interest and couponsDouble-entry ledgerfinance · low: Append-only journal of transactions whose postings sum to zero per currency; balances are derived, so money can only move, never appear or vanish.›Event sourcingfinance · low: Persist state changes as an append-only stream of immutable events per entity; current state is a fold over them, guarded by expected-version appends.›Portfolio performance metricsfinance · low: Time-weighted and money-weighted returns, Sharpe, Sortino, drawdownProration calculationfinance · low: Prorating charges and credits for mid-cycle plan changes by time usedReconciliationfinance · low: Match internal ledger records against bank and processor statements by reference, then amount and date window; every unmatched or mismatched item becomes an exception.›Process 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.›Sequenced multicast feednetworking · low: Exchange order-by-order data as fixed binary messages in sequenced UDP multicast packetsDual control approvalsecurity · low: Four-eyes / maker-checker approval with quorum policies for sensitive operationsMutual TLSsecurity · low: TLS where the client also proves a certificate key, so every connection carries a verified, rotatable machine identity.›+ 12 more techniques+ 61 more primitives
