⭐ Today's Picks

1. We Replaced Our Sales Team with 20 AI Agents

Source: Lenny's Newsletter Summary: SaaStr's Jason Lemkin shares his experiment replacing a 10-person SDR/AE team with 20 AI agents. Details the specific workflow using Claude, HubSpot, and Outreach, now managed by just 1.2 people. Why I recommend this: Real experiment results, not theory. GTM leaders can preview how sales organizations will transform in 2026, plus get hints on becoming "hyper-employable" in the AI era.

2. Message Brokers 101: Storage, Replication, and Delivery Guarantees

Source: ByteByteGo Summary: Explains the fundamentals of message brokers in distributed systems. Covers producer-consumer decoupling architecture, buffering during traffic spikes, and their role as sophisticated distributed databases beyond simple pipes. Why I recommend this: Essential knowledge for developers working with microservices architecture. ByteByteGo's signature visual explanations make complex concepts accessible.

3. Cloudflare's Outage Proves Dangers of Global Configuration Changes

Source: Pragmatic Engineer Summary: Analyzes root causes of Cloudflare's major outages occurring two weeks apart. Examines the structural problem of global configs deploying instantly across the entire network, and similar incident patterns at Meta, Google, and others. Why I recommend this: Valuable lessons from large-scale infrastructure failures. A compelling case for why staged deployment systems matter.
