Building TNP: Why I Built an Enterprise-Realistic DevOps Lab (Part 0)

🧭 This is Part 0 of a 10-part series documenting a self-built, enterprise-realistic DevOps lab — modeled after a fictional fintech company, not a pile of unrelated tools. TL;DR Most homelab tutorials teach tools in isolation. This series teaches them working together, inside a fictional company with real constraints. Meet TNP Technologies — a fictional fintech with 150 employees, hy...

The $0.13 API Token: Inside the Underground Relay Market for AI Access

Here is a number that does not make sense: $3,333 worth of official Anthropic API credit, sold for 425 RMB. That is roughly $59. The buyer pays fifty-nine dollars and receives over three thousand dollars worth of API access to frontier models. The effective rate: about $0.13 of official usage per dollar spent -- a 97.8% discount off the list price. This is not a group-buy discount or a startup p...

Is Building in Public Backwards?

I used to post the roadmap. The coming-soon screenshot, the "building something new" teaser, the thread narrating a feature I had not finished. It felt like momentum. Building in public, the advice everyone gives: share the journey, bring people along, market as you make. I stopped. Not because visibility is bad. I publish more now than I ever did. I stopped because I had the sequence backwards, ...

TIL - Choosing Between Code, an LLM Call, and an AI Agent

Two questions sent me down this path. Question one: what is an "AI agent," really? Most job posts mention them. I had not looked into it deeply, and from the outside I could not tell what it referred to. Is an agent a different endpoint? A different model? A library we install? Or is it just a name for calling an LLM API in some particular way? Question two came later, and it stopped me cold. On...

Auditing Agent Skills: A Threat Model for the Next Generation of AI Package Managers

Let me start with a question. If a stranger handed you a USB drive and said "plug this in, it just organizes your files," would you do it? Probably not. Most of us have had the "don't plug in random USB drives" lesson drilled into us for years. Here's the thing though: right now, thousands of developers are doing the exact digital equivalent of that, every single day, without even realizing it....

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...

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...

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...
