Hot reload on Next.js routes still shows an error even after the bug has been fixed

I'm new to React and Next.js, and I'm running into a really annoying caching issue. When I have a api/auth/route.ts , and an error is detected in this file (a basic syntax error), even after I fix the error, hot reload refuses to reload the file properly. I have to restart the server with “npm run dev,” which takes a long time. I recorded a video of the issue: https://orbika.fr/uploads/react-cache...

Breaking web apps

Introduction THOR (The Hand Book of Open-source Repositories) is a website that provides world-class guidance on open-source contributions. This is very near and dear to my heart. Ever since I was 18 years old in 2019, I watched my friend get selected for G-soc. I struggled to understand how to go about it and I was always wishing I had a medium that would provide a very clear understan...

Backend AI Needs an Action Surface, Not Just a Chat Box

Most AI developer tooling still assumes the main interface should be a chat box. That makes sense for open-ended questions. It makes less sense for day-to-day backend work. Backend workflows usually do not begin with a blank prompt. They begin with a broken startup command, a noisy terminal, a health check issue, a confusing project tree, a module decision, or a team convention that the AI does ...

Google’s 75% AI-Generated Code Claim Hides the Real Shift

Google says AI-generated code now accounts for 75% of all new code at the company, with that code still “approved by engineers.” That line came from CEO Sundar Pichai’s April 22, 2026 Cloud Next post, and it extends a public progression Google has now repeated for three straight reporting periods. The numbers are straightforward. The meaning is less so. Google is not saying 75% of its entire code...

Using AI to Build Your Year-End Performance Case

Most engineers lose their appraisals in June. Not because they underperformed — because they forgot what they shipped. Your manager tracks 8-12 reports across 40 weeks. If you walk into December with "I think I did good work?" you've already lost. The problem is mechanical. Brag documents require weekly discipline most people don't have. Miss one week, friction compounds, you stop forever. Claude...

How to Actually Use AI Coding Agents — 6 Skill-Specific Tips

1. Where Vibe Coding Breaks Last year I was adding one more BLE sensor node to a Zephyr-based nRF52 firmware. I threw a one-liner at Claude Code — "enable the SPI driver" — and a single clean line landed in prj.conf: CONFIG_SPI_NRFX_SPIM3=y. The build passed. The binary flashed. The board would not boot. Thirty minutes of digging later, it hit me — that symbol does not exist anywhere in...

Full Attendance, Zero Presence

Five minutes after the all-hands, someone asks me in the hallway, "What did he mean by that?" Then another person: "So what are we actually supposed to do?" I didn't have a great answer either. We'd all sat through twenty minutes of a strategy change presentation. We all nodded. None of us was in the conversation. This isn't a one-off. I see this pattern everywhere – across teams, across function...
