Creating pop-ups and modals on your site can be a complicated process. And it often requires a lot of boilerplate code to get started. But the real challenge comes when you want to make that modal or

In this tutorial, I'll show you how to evaluate a local AI agent with a simple, repeatable evaluation harness. The harness runs the agent against a set of test cases, checks the results with both rule

Last year a client called me about exactly this. Someone ran git log -p on a hunch and found a .env committed two years earlier, never caught. Database password, Stripe secret, JWT signing key — all s

Software engineers often think reliability is a modern challenge. We discuss uptime, distributed systems, observability, and fault tolerance as if they belong exclusively to cloud computing. In realit

It's mid 2026, and the best frontier models out there still hallucinate. I want you to gain two things from reading this article: understanding that AI hallucinations are still real and possibly harmf

Health data is having a moment. Of all the metrics receiving the most developer interest at present, there’s nothing like heart rate variability (HRV). It’s a feature found on every major SDK for wear

A colleague asked me to help debug what looked like a permissions issue in their SaaS project management tool. Users were seeing resources they hadn't created. I pulled up the query logs expecting som

PDF documents are commonly used for agreements, forms, approvals, invoices, reports, applications, and other documents that may need a signature or additional text before they are shared. A traditiona

In this article, you'll learn how to optimize SQL Server performance using T-SQL query tuning, indexing strategies, execution plans, and real-world optimization techniques for enterprise applications.

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 Mac, a capable language model is already on your d

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. Instead of interacting with the agent through a termin

You asked the AI to write a function. It gave you something that looks right. It even runs. But is it actually good? Most engineers stop there. They see green and move on. That habit will quietly caus

Most prompt engineering tutorials follow the same shape. Install the SDK, paste your API key, call generateContent, and print the response. The model says something plausible and the tutorial ends. 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 need a calendar, a time selector, a state that keeps

Most segmentation tutorials begin by choosing a model, feeding images into it, and tuning hyperparameters until the metric improves. But this skips the step that often matters most: understanding the

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 tracing for it so that we can inspect model calls

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 the edit loop. Every small change ("move this bull

Retrieval-Augmented Generation, commonly known as RAG, has become one of the most widely used approaches for building applications with large language models. Instead of asking an LLM to answer entire

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 authentication service talks to a user service. A d

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 the screen and into the physical world. If you've n
