The same architect title means a different job at every company. In this article, we sort architect roles by decision scope, compare them with Staff Engineer and Engineering Manager, and give seven questions to decode any architect job post.
An index can turn a slow query into a fast one, or slow down every insert on the table. In this article, we explain database indexing in SQL Server, PostgreSQL, and MySQL: eleven index types, when to use each one, when to avoid them, and how to find missing and unused indexes.
Weekend Reading: A weekly roundup of interesting Software Architecture and Programming articles from tech companies. Find fresh ideas and insights every weekend.
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.
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.

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.
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.
