The best Distributed Systems newsletters

An engineering blog from the Sequin team covering Postgres change data capture, pipeline architecture in Elixir, and product announcements. Readers get detailed explanations of design decisions such as back-pressure, delivery guarantees and duplicate handling.

A technical newsletter from a software engineer that explains computing fundamentals and system design in depth, such as floating-point representation, caching data structures, and API communication patterns. Readers get structured, practical explanations they can apply to real engineering work.

A technical blog from LambdaClass covering cryptography, distributed systems, formal verification, compilers and security, with posts on their PropAMM Router and Factory, audits, and devnet performance results. Readers get detailed engineering write-ups on Ethereum market-making infrastructure and consensus-layer performance findings.

This newsletter covers system design for backend engineers, with a recent focus on building reliable AI agent systems. Issues use concrete failure scenarios to explain concepts such as agent state, memory, and observability.

Engineering blog from Acceldata sharing practical write-ups on their internal systems: adding forecasting and anomaly detection to VictoriaMetrics dashboards, diagnosing performance bottlenecks in a high-throughput Scala microservice, and designing a Kubernetes logging platform with Vector, Kafka and OpenSearch. Readers get concrete architecture and debugging walkthroughs from production experience.

James Coffee writes about software engineering, mixing technical essays on distributed systems and timing with personal opinion pieces and project announcements. Readers get practical reasoning about how systems really behave, plus candid takes on the ethics of using AI tools.

A software engineer's blog covering software design, architecture, domain-driven design and distributed systems, with posts on keeping domain models rich and on message design in event-driven systems. The excerpts are short and mostly introductions, so the depth of individual posts is only partly visible.

Engineering blog posts from Synerise's AI and big data lab covering workflow automation throughput, sequential recommendation benchmarks comparing TIGER and LIGER, and streaming optimization in the Terrarium SQL engine. Readers get concrete architecture details, benchmark comparisons and performance-tuning patterns from practitioners.

High Scalability republishes and curates engineering write-ups on building large-scale systems, often reposting articles from company engineering teams and guest authors. Readers get technical case studies on architectures such as Kafka, real-time features at streaming platforms, and how Uber scaled its backend.

Company blog from Pragma, an oracle infrastructure project, announcing product releases such as the Calf Narwhal implementation, Pragma v2 and an optimistic oracle on Starknet. It explains the technical and market reasoning behind each launch for blockchain developers.

Tech Talks Weekly is a free weekly email that curates recently published conference talks and podcasts for software engineers and engineering leaders, with short descriptions and links. Its issues are mostly lists of talks with promotional blurbs for sponsored events and a paid Plus tier.
