Your LLM product experiment just came back positive, with a promising 8-percentage-point lift in task completion. You ship the feature and leadership celebrates. Three months later, the core metric has barely moved. The experiment was statistically sound. It simply answered the wrong question. An average treatment effect compresses the entire treatment response across your user […]
A Postman collection is a great place to explore an API. But it’s a poor place to keep your tests. Most teams find this out the slow way. Someone exports the collection, converts the requests into test code once, and moves on. Six months later the tests are red, nobody trusts them, and they get […]
Technology changes faster than almost any other industry. The half-life of technical skills continues to shrink. Frameworks, cloud platforms, AI tooling, and cybersecurity practices evolve so quickly that knowledge gained two years ago may already be outdated. New programming languages emerge, frameworks evolve, security threats become more sophisticated, and development practices continue to shift. For technical […]
A new type of app is emerging with the development of LLMs and AI-native apps. It lives inside an AI chat (like ChatGPT) rather than being a fully native web or mobile app. In this tutorial, you’ll learn how to build an MCP (Model Context Protocol) server from scratch, including a UI you can use […]
The first time I built an API without thinking about roles, I gave every logged-in user the same access. It worked fine until a regular user accidentally hit a delete endpoint and wiped test data. That was the day I actually sat down and learned RBAC properly. Role-Based Access Control sounds fancy, but the idea […]
Artificial intelligence has moved far beyond simple chatbots and basic automation. Today, developers and non-developers alike use AI tools to research information, write content, create presentations, manage projects, and analyse data faster than ever before. The biggest advantage of AI is not that it replaces people. Instead, it helps people spend less time on repetitive […]
PDF files are one of the most widely used document formats for sharing reports, invoices, contracts, books, research papers, manuals, forms, and business documents. Although viewing a PDF is simple, understanding what’s inside the document is often much more difficult. For example, you may need to know how many pages a PDF contains, whether it’s […]
Add a product to a Shopify store the default way and the whole page reloads. The shopper is looking at your product, they click Add to cart, and the browser throws the page away and rebuilds it. On a slow connection, that’s two or three seconds of blank screen. Sometimes they even land on /cart, […]
