MCP bridges the gap between your AI agents and your external tools, allowing them to send Discord messages, read your emails, and interact with your environment. But this massive leap in capability co

A website user interface (UI) used to take hours of writing HTML, CSS, and component code by hand. Now you can describe a page in plain words and let an AI coding tool write the first version. But the

In my previous article, I explored operational conformance: how to evaluate whether observed evidence satisfies an operational specification. That gives us a useful point-in-time question: Does the s

Most Android tutorials stop at "it runs on the emulator." But getting an app from a blank project to a listing that real people can install from Google Play involves a second half that's rarely discus

I got tired of coding agents telling me the frontend work was done when nobody had opened the frontend. You've probably seen the routine. The agent changes some code, runs the formatter, the type chec

Many AI agent tutorials start with a language model, give it a few tools, and run a loop until it produces an answer. That's enough to demonstrate tool calling, but it leaves the interesting engineeri

Your smart ring or watch has many useful jobs, including learning your usual physiological patterns and showing you when they change. Resting heart rate, heart rate variability (HRV), temperature, and

A straight line equation is a good place to start understanding how a neural network works. It's what we explored in my previous article, How Neural Networks Work – Explained Using the Straight Line E

Most application search setups force a trade-off: settle for simple text filters, or manage a separate search cluster like Elasticsearch with complex synchronization pipelines. In a new video course o

I recently worked on a project where a Node.js application used Vite to compile its frontend. It worked in a browser-hosted development environment, but its image build failed after the move to Azure

Over time, knowledge has been passed down in various forms. Before writing was invented in ancient Mesopotamia (modern-day Iraq), laws, history, myths, songs, and other information were all transferre

I scanned 111,076 of the top 200,000 websites on the internet looking for a specific HTTP header. I found exactly zero. Not one domain has shipped WebMCP in production. Not a single Fortune 500 site.

Web scraping has evolved. If you’ve ever tried to pull data from a site, only to be hit with a CAPTCHA, an IP ban, or a "403 Forbidden" error, you know that modern websites are built to block automate

I built a clean, well-structured deep learning pipeline using MONAI (Medical Open Network for AI) on a public abdominal ultrasound dataset. The pipeline included: proper subject-grouped train/validat

Wearable IoT technology has become an important part of today’s elder care, as it can help detect falls and alert caregivers or family members immediately after an incident. This technology combines s

If you’ve built a RAG (Retrieval-Augmented Generation) system in the past year, you’ve probably hit the wall where your LLM returns confidently wrong answers, cites information that doesn’t exist, or

Every company says it wants speed. Roadmaps talk about velocity. Leadership meetings talk about reducing cycle time. Quarterly goals talk about faster execution and quicker releases. Every business wa

HTML has always supported streaming. The server doesn't need to build an entire page in memory before sending it to the browser. It can send the initial HTML first, then send more chunks as each chunk

It’s been three years since I started using my wearables to count my steps. Three years of trying to hit the daily 10K target, closing rings, and going to sleep knowing that I accomplished something p

When you're working with contracts, reports, invoices, manuals, or academic documents, page numbers make navigation much easier. Instead of manually editing every page, modern JavaScript libraries let
