Thoughts, notes, and experiments on design, engineering, and craft.
This post goes through all of it. First the idea, then the five algorithms with small examples, then the limits real systems use (Stripe, GitHub, AWS, NGINX), and then the two limiters I run in my own projects, Edward and Agentic Chat, with what is good and what is not.
Learn when to use message queues, event streams, SSE, and WebSockets in real-time systems. A practical guide with code examples for engineers.
Subnetting, NAT, firewalls, WebSockets, gRPC, and GraphQL explained for developers. The practical follow-up to computer networks fundamentals.
A walkthrough of IP addresses, DNS, TCP vs UDP in practice, proxies, load balancers, and CDNs.
A walkthrough of computer networks: nodes, IPv4 vs IPv6, topologies, packets, TCP vs UDP, and the OSI model.
A deep dive into Edward's architecture. Learn how chat messages become fully deployed applications through agent workflows, sandboxed execution, streaming protocols, Docker isolation, build pipelines, and real-time orchestration.
