Your AI Agent Says All Tests Pass. Your App Is Still Broken

How Knight Rider Testing Gave Me My Nights Back There is a moment every developer using AI coding agents knows well. You wake up, check your terminal, and see the beautiful green wall: 47 tests passed, 0 failed. You open the app. The button does nothing. The layout is sideways. The feature you asked for doesn't exist. The agent rewrote half the codebase, generated tests that validate...

Azure AI Agent Function Calling: Connect Your Agent to APIs with Terraform 🔌

An Azure AI agent without tools is just a chatbot. Function calling gives your agent the ability to invoke your code when it needs real data or actions. Here's how to define functions, handle tool calls, and wire up the infrastructure with Terraform. In the previous post, we deployed an Azure AI agent that can reason and hold multi-turn conversations. But it can only generate text from what the m...

Building a High-Performance Cache Layer in Go

Your service is slow. You add Redis. It gets faster. Then Redis becomes the bottleneck -- every request still makes a network round-trip, serialization costs add up, and under load you start seeing latency spikes from connection pool contention. Sound familiar? In this article, we'll build a two-tier cache layer in Go that combines a local in-memory cache with Redis, prevent cache stampedes using...

We built an AI IDE where all orchestration lives server-side (thin client) here are the architectural tradeoffs

We've taken a server-side orchestration approach with Resonant IDE, an open-source VS Code fork. The IDE extension itself is a thin client responsible for rendering the UI, running 59 local tools, and streaming data via SSE. All the heavy liftingsystem prompts, tool selection, the agentic loop, and routing between LLMs like Groq, OpenAI, Anthropic, Gemini, and local Ollamahappens on the server. T...

Why Your "Fail-Fast" Strategy is Killing Your Distributed System (and How to Fix It)

Why Your "Fail-Fast" Strategy is Killing Your Distributed System (and How to Fix It)

It's 2 AM. PagerDuty fires. Redis master is down. Your application, trained to fail fast, dutifully fails — every single request, all at once. By the time Sentinel promotes a new master 12 seconds later, you've already generated 40,000 errors and three escalation calls. The system recovered on its own. Your application didn't let it. This is the story of how "good engineering" can make a 12-secon...

I Replaced Google Drive with a Home Server That Costs Almost Nothing

I was paying ₹650/month for Google One's 2TB plan. That's ₹6,500 a year — for storage I don't own, on servers I don't control, where my photos could be used to train AI models. Then I looked at the old HP Pavilion x360 collecting dust on my shelf. 1TB hard drive. 8GB RAM. A perfectly good Intel i5 processor doing absolutely nothing. What if I could turn it into my own cloud? Turns out, you can....
