🔖 The Reading Room
Articles we have hand-picked for you: | | |
Next.js 16
Next.js 16 is now available with Turbopack as default bundler (2-5× faster builds), Cache Components for explicit caching, proxy.ts replacing middleware.ts, improved logging, React 19.2 support, and breaking changes including async params requirement. By Next.js team → |
| What caused the large AWS outage?
A 14-hour AWS outage in us-east-1 took down thousands of sites when DynamoDB's DNS records were completely emptied due to a race condition between DNS Enactors. Even after DynamoDB recovered, EC2 remained down for 12 more hours due to cascading failures in lease management and network propagation systems.

How to fix any bug
Dan goes through a scrolling bug in his app to explain his debugging process: establish reliable reproduction steps, narrow the repro to something measurable (not just visual), incrementally remove code while ensuring the bug persists at each step, and avoid getting distracted by unverified theories. By Dan Abramov → | |
Developer Flow
Most developers struggle to achieve flow state for more than half an hour due to constant interruptions, meetings, and context switching. Research shows it takes 23 minutes to reclaim flow after a single interruption, yet the average developer faces disruptions every 3-10 minutes.

We Will Not Trust Autonomous AI Agents Anytime Soon
The fatal flaw in autonomous AI agents isn't technical capability but something more fundamental: care. While a careless human worker faces consequences, AI agents operate without genuine concern for outcomes, making them fundamentally unsuited for trusted autonomous decision-making.
