Building AI features is straightforward until you need to integrate them into a production system. In production, a simple ‘call an LLM’ often becomes: wiring HTTP/JMS/Kafka/file inputs, enforcing timeouts, retries, fallbacks, stitching context obtained from internal data sources, protecting secrets, making it testable without burning API credits, and ensuring the system is observable when issues … Read more

Assets Use reliable stablecoins from trusted issuers, where the probability of a depeg is very low. The … Read more

A book first published in 1962—Thomas Kuhn’s The Structure of Scientific Revolutions—isn’t where you’d expect to find guidance for shipping production AI. But Kuhn’s core point about paradigms clicked instantly for me: reliability starts when you make your “world” explicit—what exists, what’s allowed, what counts as evidence—and then enforce it. That’s exactly what I needed … Read more

High-scale systems fail in many unexpected ways that you would never have designed for. Over the course of the last 14 years, I have navigated the layers of physical and virtual networking. I started out as an individual contributor writing code for data plane services and transitioned to leading global teams managing highly distributed services … Read more

I discovered nport (https://github.com/tuanngocptn/nport) – a fantastic ngrok alternative built in Node.js. It’s free, open-source, and uses Cloudflare’s infrastructure. But I wanted something with: Smaller footprint – Single binary, no Node.js runtime Faster startup – Go’s compilation speed Better concurrency – Native goroutines Learning opportunity – Deep dive into tunneling tech So, I decided to … Read more

The “House of G.E.T.S.” Technical Deep-Dive In today’s article, we’ll take a look at the first “Wall” most offensive security students hit: The Null-Terminator Constraint. I don’t blame the students for hitting it; it’s the first wall that many instructors also gloss over. I’m not just talking about the standard “identification of bad characters”—though they … Read more

Software Engineer, Joachim, shares his first 5 years in review. Joachim shares his top tips on how to succeed as a software engineer.

Software engineers tend to judge older code without understanding its context. Code is only the visible part of the story, but not the context in which decisions were made. Deadlines, team size, available tools, business pressure, and technical limitations rarely survive in repository.

I was at a play the other night, the kind of small auditorium where half the seats were empty. It was the sort of setting where you can hear someone cough three rows away and feel personally involved in their illness. After the show, I ran into one of the actors. A young actor, the … Read more

If you’re comparing Outlook and Gmail for business security, this probably isn’t a casual choice. Maybe you’ve had a phishing scare that got uncomfortably close. Maybe leadership asked, “Are we actually secure here?” — and you couldn’t answer with full confidence. Or maybe compliance, audits, or client expectations are starting to matter more than they … Read more
