RECENT EDITION VIEWS
What recent editions said about Coding.
Coding agents make code cheap to produce, so review becomes the constraint. Educators and practitioners are changing courses, PR conventions and even whether to use libraries at all.
November 9, 2026 edition: Coding sector, 3 storiesOpenAI is buying Pierre to give Codex Git infrastructure built for parallel agent traffic. A Reddit comparison of website-building agents mostly reflects quotas and deployment limits rather than output quality.

Claude Rebuilds a 16,000-Line Program From Its Behavior Alone as Anthropic Restricts Game Cloning in Claude Code
Across four Claude Opus versions, behavior-only reimplementation of one 16,000-line program rose from 15% to 99.95% of tests passed, yet broader benchmarks show far weaker results and Anthropic has begun steering Claude Code away from cloning existing games.
Podcast · Agents
Resend CEO Zeno Rocha says products should be API-first for AI agents as the company's MCP server reaches about 1.2 million calls in August
Resend CEO Zeno Rocha argues developer products should be API-first so agents, CLIs and people can each use them their own way.
Models
Google makes Gemini 4 Carbon generally available at half price until November 30, and llm-gemini 0.36 adds support
Google opened Gemini 4 Carbon to paying API developers and subscribers on November 10, two weeks after limiting it to cyber defenders.
Agents
Vercel Connect opens public beta for MCP Events, letting AI agents subscribe to MCP server webhooks instead of polling
Vercel has put MCP Events support in Vercel Connect into public beta, so agents can receive signed webhook events from compatible MCP servers rather than polling them.
Research
DeepMind's AlphaProof Code agents produce machine-checked Lean proofs of security properties in Signal's compiled cryptographic code
