Orchestrating a multi-agent solution with the Microsoft Agent Framework

The World Cup is over, and despite England losing in the semi-finals, there were plenty of successful hatewatches to be enjoyed (Thank you Belgium and Spain for your service). If you're sad that it's all over, the Premier League is just over 1 month away. Last season, my team Arsenal finally won the title after a 22-year drought. Arguably, we should have won the EFL Cup and the Champions League. ...

I let an AI write 6 WebGL hero sections — here's the one-CSS-variable reskin trick, and the honest review count

I've been building SDTK, a toolkit that puts real gates in front of AI-written code instead of trusting the first draft. To show what that actually buys, I pointed it at something visual and free: six "stop-scrolling" hero sections — a WebGL ember aurora, a floating 3D product, molten liquid metal, a particle swarm that spells your brand word, a scroll-driven film, and kinetic type. All six in mo...

Connect Two WebRTC Peers with Manual Signaling

WebRTC does not define how two peers exchange connection details. Normally that job belongs to a WebSocket or HTTP signaling service.

Grounded Search Agents: Microsoft Foundry + Azure AI Search + Cosmos DB + Function Calling

Why "search" isn't enough anymore A plain RAG pipeline — embed a query, hit a vector index, stuff the top-k chunks into a prompt — works fine for a single-turn FAQ bot. It falls apart the moment you need: Multi-turn memory ("what about last quarter?" needs to know what "last quarter" refers to) A decision about whether to search at all (some questions are structured lookups, not doc...

I Built an AI Team That Investigates Production Incidents Better Than Most Engineers

Built for the **SigNoz "Agents of SigNoz" Hackathon — July 2026** Production Incidents Shouldn't Take Hours to Investigate Every engineer who has been on call knows the feeling. An alert fires in the middle of the night. Dashboards turn red. Error rates spike. Customers begin reporting failures. The incident itself may eventually be simple—a database timeout, an exhausted Redis co...

Django 6.0 Tasks com TDD: três paredes que o caminho feliz esconde

O Django 6.0 trouxe um framework de tasks nativo. Segui o tutorial, funcionou de primeira — e foi exatamente aí que desconfiei. Decidi refazer tudo com TDD, escrevendo o teste antes de cada linha. Bati em três paredes que o caminho feliz não mostra.

How to review AI-generated code without losing ownership of your project

AI can finish a feature faster than we can absorb its assumptions. The practical review question is not only ‘does this work?’ but ‘could I explain why it works, where it can fail, and what it changes tomorrow?’ A useful review loop starts narrow and expands only when needed. Begin with the selected expression, then inspect its function, file, dependencies, git change, and the project decision be...

Parallel Selenium Tests in Java Without Thread-Safety Bugs

Your suite is green. Someone sets thread-count="4" to get CI under ten minutes, and now three tests fail. Re-run: two fail, and not the same two. Run it locally and everything passes. That's not flakiness in your application. That's your test framework being unsafe under concurrency, and it was unsafe the whole time — one thread was just hiding it. The advice you'll find in ten minutes of search...

The LLM Narrates, the Core Decides: Anatomy of an AI Checkout

How we built a checkout that runs the same protocol in a chat window, a voice session, and a live phone call. One word, many moves On the AI storefront platform I work on, a customer can type "checkout" into a chat window — or say it to a voice agent or a phone line — and, a short conversation later, they have an order number. The transcript looks unremarkable: a question about special...

Your Turn Is a Session Handoff, Not a Completion Claim

When a coding agent stops producing output, the next step is not automatically yours. It may be waiting on a tool, calculating, stalled, or actually finished. A useful your-turn state needs stronger evidence than silence. The definition I use is narrow: your-turn means a specific Claude Code or Codex session has produced evidence that the next useful action belongs to the developer. Pro...

Building a Dice Roller That Teaches Probability: Batches, Histograms, and CSV

A dice roller looks like a one-line project: const value = Math.floor(Math.random() * 6) + 1; That line is enough to draw a number from 1 through 6. It is not enough to make a useful probability tool. The interesting engineering begins when a user asks the next questions: Can I roll several dice at once? Can I run 10, 50, or 100 trials without freezing the page? Is the result distribut...

Lemonade Second Squeeze: Model Archeology on 2019's GPT-2XL

Two weeks ago I had never run an AI model on my own machine. Every project I had ever built phoned a cloud API with a key sitting in it. Then I sat in the vibecoding lab at AMD's Advancing AI 2026 summit and watched a model answer a question from a laptop, nothing leaving the room, and I got the itch. I have a pattern. When something lights me up, I chase it before I am ready. This was that. I pi...
