Mechanical Sympathy

A software design philosophy, coined by Martin Thompson from motorsport, that aligns program behavior with underlying hardware constraints — CPU cache hierarchy, memory access patterns, and concurrency primitives — to achieve lower latency and higher throughput without additional hardware.

Tree-sitter

Incremental parser generator and parsing library that builds concrete syntax trees for source files and updates them efficiently on edit, supporting 100+ programming languages and used by Neovim, GitHub, and AI coding tools.

open-source MIT

Supabase

Open-source Firebase alternative providing managed PostgreSQL, authentication, storage, and serverless Edge Functions as a Backend-as-a-Service; 4M+ developers, $70M ARR, $5B valuation (October 2025).

vendor Apache-2.0 (platform code); managed service Proprietary

Trigger.dev

Open-source Apache 2.0 TypeScript background jobs and AI workflow platform with durable execution, no-timeout container-based runs, and a managed cloud offering; 14.6k+ GitHub stars, $20.3M raised.

Actor Model

A concurrency model where computation is organized as independent 'actors' that communicate exclusively by passing asynchronous messages, each actor processing one message at a time — eliminating shared mutable state and the need for locks.

CQRS (Command Query Responsibility Segregation)

An architectural pattern that separates write operations (commands) from read operations (queries) into distinct models, enabling independent optimization, scaling, and technology choices for each path — particularly useful in high-throughput or event-sourced systems.

Inngest

Event-driven serverless workflow platform for TypeScript and Python that runs durable step functions by calling your existing HTTP endpoints — no dedicated workers or queues to manage.

LMAX Disruptor

A lock-free, cache-friendly inter-thread messaging library for Java that uses a pre-allocated ring buffer and mechanical sympathy principles to achieve over 25 million messages per second with sub-50 nanosecond latency — orders of magnitude faster than standard bounded queues.

open-source Apache-2.0

Natural Batching

A batching strategy where a consumer thread starts processing a batch immediately when the first item arrives and completes when the queue is empty or a maximum batch size is reached — avoiding the fixed latency penalty of timer-based batching and the blocking risk of size-fixed batching.

PowerSync

Offline-first database synchronization service that keeps PostgreSQL, MongoDB, MySQL, or SQL Server backend databases in sync with client-side SQLite via a partial-replication engine; SOC 2 and HIPAA compliant with both managed cloud and self-hosted FSL-licensed options.

vendor FSL (service) / Apache-2.0 (client SDKs)

assess

Single Writer Principle

A concurrency design principle where all mutations to a shared data structure are performed by exactly one designated thread, with other threads communicating writes via asynchronous messages — eliminating mutex locks and cache-coherency contention.
