Last year, our ML team shipped a fraud detection model that worked perfectly in a Jupyter notebook. Precision was excellent. Recall numbers looked great. Everyone was excited – until we tried to deploy it. The model depended on a specific version of scikit-learn that conflicted with the production Python environment. The feature engineering pipeline required […]

Before I started building auth into my own projects, I didn’t think too deeply about what was happening to passwords behind the scenes. Like most developers, I installed a library, called a hash function, stored the result, and moved on. I see a random string like (2a11yMMbLgN9uY6J3LhorfU9iu…. in my database and assume my user’s passwords […]
Depending on cloud apps means that you don’t truly own your notes. If your internet goes down or if the company changes its rules, you could lose access. In this article, you’ll learn how to build your own private workspace using AFFiNE. You’ll use Docker Compose to link three separate pieces of software together: The […]
Recursion is when a function solves a problem by calling itself. It sounds odd at first — why would a function call itself? — but once it clicks, you’ll find it’s often the most natural way to express certain kinds of problems in code. In this article, you’ll learn what recursion is, how it works […]
I have noticed that many engineers who run Kubernetes in production have never actually watched it heal itself. They know it does. They have read the docs. But they have never seen a ReplicaSet controller fire, an OOMKill from kubectl describe, or watched pod endpoints go empty during a cascading failure. That’s where 3 am […]
There’s a perception problem with Docker Compose. Ask a room full of platform engineers what they think of it, and you’ll hear some version of: “It’s great for local dev, but we use Kubernetes for real work.” I get it. I held that same opinion for years. Compose was the thing I used to spin […]
Today Quincy Larson interviews Justin Searls. He’s a software engineer who cofounded a software agency 15 years ago that’s still going – even after he figured out how to make a lot of money quickly and retire at age 38 once he had enough savings. These days he’s gone from solving problems for client to […]
Vibe coding is about momentum. You open your editor, prompt an AI, stitch pieces together, and suddenly you have something that works. Maybe it’s messy. Maybe the architecture is not perfect. But it’s live and working, and that’s the point. Then comes deployment. This is where the vibe usually dies. Suddenly, you’re reading about containers, […]
Whenever engineers are building AI-powered applications, use of sensitive data is always a top priority. You don’t want to send users’ data to an external API that you don’t control. For me, this happened when I was building FinanceGPT, which is my personal open-source project that helps me with my finances. This application lets you […]
Today Quincy Larson interviews Carl Brown, who runs the Internet of Bugs YouTube channel and has worked as a dev at Amazon, IBM, Sun Microsystems, and startups for over 37 years. We talk about: The hype versus the utility in LLMs and agent code generation tools Why you might want to target developer jobs at […]
