This week: bool.dev explains how Raft commits writes and survives failures; Uber composes search indexes across independently owned services; Meta moves reusable privacy checks into data-access libraries; and LinkedIn connects user interactions to backend traces with OpenTelemetry.
How Raft keeps several servers in agreement when any of them can crash: one leader, a majority vote, and a write that counts only after most servers store it. Explained step by step, with diagrams and no math.
The habits that got you promoted, like having the answer first and closing tasks yourself, slow your team down once you manage it. Here are six things I'd tell every new engineering manager, with a concrete action for each.
This week: Anthropic redesigns code review around evidence and risk; LinkedIn combines generated data documentation with owner-maintained knowledge; Uber reduces translation-cache memory without introducing network calls; and Stripe discovers why more training data can make fraud detection worse.
This week: two bool.dev guides on hidden EF Core costs and consolidating microservices without losing module boundaries; Booking.com’s production investigation into Node.js resource efficiency; and LinkedIn’s move to a dedicated shuffle service for Spark and Flink.
Every migration guide explains how to split a monolith. This one goes the other way: a test for which services to merge, and seven patterns for merging them back into a modular monolith without a big-bang rewrite, each with its cost.
Weekend Reading #98: AI agent terminology, Uber’s MCP Gateway, Zalando’s delegated identity broker, and Meta’s petabit-class subsea cable design.
30 AI terms in two or three plain sentences each, placed on one diagram: what the model sees, what it can call, and what runs around it. MCP, skills, hooks, subagents, RAG, workflows, and the pairs people mix up.

Once an AI agent can push to Git, prompt injection becomes an authorization problem. Six things to build before agents get write access: a scoped identity, a policy outside the model, a sandbox, MCP review, advisory CI, and traces.
EF Core makes the slow path look exactly like the fast path. A scan, an N+1 loop, and a Cartesian join all read like clean LINQ. This guide walks through 18 concrete mistakes across querying, related data, change tracking, indexes, plan caching, and context overhead, with the fix for each and a ready-to-use rule for your AI coding assistant.
Weekend Reading #96 covers AI controls across the SDLC, Meta’s confidential processing architecture for AI glasses, automated dependency analysis across Uber’s service mesh, and Elastic’s benchmark-driven system for safely optimizing Elasticsearch with coding agents.
AI across the software development lifecycle, from requirements and architecture to coding, testing, deployment, operations, security, and compliance. Practical guidance on AI authority, deterministic controls, human ownership, and safe engineering workflows.
