A Litecoin Wallet That Remembers Nothing

In a previous article we introduced Ritual Protocol. Today we look at how it works in a real application. Imagine: you need a new address on a blockchain network, or you want to access an existing one. You place some runes, point to London at 12:47, and tap a sequence of emojis. That's it. Cold wallet ready. No custodial nonsense, everything by the book — the way Satoshi intended. The only differ...

Why your React app feels slow (and how to fix it)

Everything seems fine… until it isn’t. You can have a React app that feels instant with a small number of users, and then suddenly it starts struggling as load grows. In most cases, the issue isn’t the server or network — it’s inefficient rendering on the client. The real gap between an “okay” app and a fast one is how predictable and controlled your renders are. What actually triggers ...

The Constraint Was Never Knowledge

There is a category of work that every experienced engineer knows matters and almost nobody does consistently. Not because they lack the skill. Not because they do not value it. Because the deadline is already here. Modeling state before writing a line of it. Stress-testing an architecture before committing to it. Understanding a system before modifying it. The preflight work. The thinking that s...

Building High-Performance Vector Search in Node.js with FAISS — Without Blocking the Event Loop

If you're building a RAG pipeline, semantic search engine, or AI-powered app in Node.js, you've probably hit the same wall I did — vector search libraries that freeze your entire server while searching through embeddings. Today I want to share faiss-node-native, a project I've been building to fix exactly that. What is Vector Search and Why Does It Matter? Modern AI applications — c...

RedSOC: Open-source framework to benchmark adversarial attacks on AI-powered SOCs — 100% detection rate across 15 attack scenarios [paper + code]

I've been working on a problem that I think is underexplored: what happens when you actually attack the AI assistant inside a SOC? Most organizations are now running RAG-based LLM systems for alert triage, threat intelligence, and incident response. But almost nobody is systematically testing how these systems fail under adversarial conditions. So I built RedSOC — an open-source adversarial evalua...

I built SSR in NGINX using njs. Here’s what I learned

I built a minimal SSR runtime directly inside NGINX — and ended up using it in production. For some time, I’ve been using NGINX with njs for things like CSP nonce generation and request-level logic. This started as an extension of something I was already using in production (CSP handling in NGINX). At some point I asked myself a simple question: can this go a bit further? This started as a ...

We built an accessibility tool because spreadsheet audits were killing us

There's a specific kind of despair that comes from opening the ninth spreadsheet in a WCAG audit, the one you're pretty sure somebody duplicated from the wrong version two weeks ago, and finding that step 14 of the login journey is marked "Fail" in your copy and "Not Tested" in the reviewer's copy. Which one is right? Nobody knows. The tester who originally logged it is on PTO. The screenshot is ...

Your staging environment is lying to you

I got a call from a client on a Tuesday morning. Their checkout flow was broken in production. Users couldn't complete purchases. Revenue was bleeding. The thing is, their staging regression suite had passed. Every test green. The deployment went through without a hitch. And yet real users were hitting a payment confirmation page that spun forever, because a third-party webhook URL had been updat...

The non-functional tests nobody runs until production breaks

We had a client ship a healthcare portal in 2021. They'd done unit tests, integration tests, a full regression suite. The build was green. The demo looked great. Three weeks after launch, an audit found that patient records were being transmitted over an unencrypted internal API call. Not the main one, a secondary endpoint that pulled appointment summaries. Nobody had run a compliance test agains...

If AI writes the code, who tests it?

I watched a developer ship a complete booking feature last Tuesday. Start to finish, about three hours. The kind of thing that would have taken a sprint two years ago. He'd used Cursor, Claude, some Copilot autocomplete. The feature worked in the demo. It crashed in staging within fifteen minutes because nobody had tested what happens when two people book the same slot at the same time. That mome...
