Curated development tutorials from top sources. Filter by language.
In this tutorial, I’ll show you how prompt engineering and context engineering can improve an AI agent's performance. We’ll build a simple local agent
Most developers begin their automation journey similarly. They create a script that performs a helpful task, such as pulling data from an API, resizin
Last year, a client asked me to add a conversational interface to their internal reporting tool. Staff would type a question, and the system would pul
Two years ago, AI coding tools were a curiosity. Agencies let junior devs experiment with them on internal tools and side projects, the kind of work w
When developers transition from the relational world (MySQL, PostgreSQL) to Firestore, Firebase's NoSQL document database, they often bring their old
If you've ever loved the speed of building backend servers with Express.js, but wished you didn't have to guess at types or debug silly runtime errors
You've built and consumed APIs. You know what a GET request is, what a JSON response looks like, and how to add an Authorization header. You've used R
When an AI assistant answers a question, it lifts sentences from a handful of pages and cites them. Whether your page is liftable is not a mystery or
In this article, you'll build an accurate mental model of what a Container Network Interface (CNI) actually does. Not by reading YAML, but by doing ev
Most tutorials on programmatic advertising stop at the web banner. That's a shame, because the idea gets far more interesting once you follow it off t
Every application, at some point, needs to talk to another system. A mobile app talks to a backend. A backend service talks to a payment gateway. An a
Retrieval-Augmented Generation, commonly known as RAG, has become one of the most widely used approaches for building applications with large language
When you maintain a document for someone else, such as a résumé, a one-page portfolio, or a printable menu, the bottleneck is rarely the layout. It's
In this tutorial, I'll show you how to trace and monitor a local AI agent with LangSmith. We'll build a small local AI agent and then enable LangSmith
Most segmentation tutorials begin by choosing a model, feeding images into it, and tuning hyperparameters until the metric improves. But this skips th
A date and time picker is one of those components that looks small in a design file and turns into a real time sink once you start building it. You ne
Most prompt engineering tutorials follow the same shape. Install the SDK, paste your API key, call generateContent, and print the response. The model
When people think of Geoffrey Hinton, they usually think of backpropagation, Boltzmann Machines, Deep Belief Networks, or the deep learning revolution
In this tutorial, I’ll show you how to serve a multi-user local AI agent as a REST API using FastAPI, then add a lightweight Streamlit UI on top. Inst
Not every AI feature needs a cloud model, with its per-token bills, network round-trips, and private data leaving your machine. If you're on a modern
