𝐖𝐡𝐞𝐧 𝐒𝐞𝐫𝐯𝐢𝐜𝐞 𝐀 𝐜𝐚𝐥𝐥𝐬 𝐒𝐞𝐫𝐯𝐢𝐜𝐞 𝐁, 𝐚𝐧𝐝 𝐒𝐞𝐫𝐯𝐢𝐜𝐞 𝐁 𝐡𝐚𝐧𝐠𝐬... Service A exhausts its thread pool and crashes too. This is a cascading failure. The 𝐂𝐢𝐫𝐜𝐮𝐢𝐭 𝐁𝐫𝐞𝐚𝐤𝐞𝐫 𝐏𝐚𝐭𝐭𝐞𝐫𝐧 prevents one failing microservice from bringing down your entire architecture. How it works (just like an electric circuit breaker):

AI code review is still early. Which models work best? How strict should reviews be? How do we reduce noise without missing bugs? Where should local models fit? Those questions are better answered in the open.

Cloudflare’s free plan is kind of wild for OSS builders. Codra runs as a self-hosted AI code review engine on Cloudflare Workers: - Worker for the app + API - Queues for review jobs - KV for sessions/cache - Hyperdrive for Postgres - Workers AI support for model routing

I’m launching Codra: an open-source, self-hosted AI code review engine for GitHub PRs. Built on Cloudflare Workers, posts inline comments, tracks reviews, and supports per-repo settings, model fallbacks, and queues. For teams that want AI review without giving up control.

Your schema will cost you more than your server ever will. I learned this building an internal tool. Search suggestion cache on Postgres. Clean schema, proper indexes. At 25k rows, it felt solid. Then I modeled 1M queries x 250 regions. 250 million rows.

React Server Components are powerful, but "React2Shell" proved that power comes with a massive attack surface. WAF blindness. DoS loops. Source leaks. I broke down exactly how the exploit works and why your firewalls missed it. Link below:👇

I thought my code was perfect, until a user tried it. I recently pushed an update to AITab and felt pretty confident. But shortly after, my friend pointed out something I had completely missed something. He was spot on. The UI was flickering.

Recreated the iconic Vercel Ship 3D card for my portfolio!⚡️ Always loved the interactivity of the original, so I had to build my own version. The floaty physics are so satisfying to play with. Check it out:👉 devarshi.dev
