Federated Learning is shifting AI training from centralized servers to local devices. By moving the model to the data, developers can solve privacy silos and reduce latency. Senior developer Ahmad Wael explains the mechanics of Federated Averaging (FedAvg) and why keeping raw data local is the future of edge computing.
Ahmad Wael discusses the upcoming CSS :drag pseudo-class and ::drag-image pseudo-element. Learn how these native selectors can replace messy JavaScript event listeners, improve frontend performance, and simplify your WordPress UI development by moving interaction logic directly into your stylesheets where it belongs.
WooCommerce 10.5 introduces a major change to product permalink logic. Instead of sorting by term ID, the system now automatically selects the deepest category in the hierarchy for the URL. This update improves SEO clarity but may shift existing URLs. Learn how it works, how it affects your store, and how to revert it if necessary.
Generic language apps lack the feedback loops necessary for mastering complex languages like Mandarin. In this article, Ahmad Wael explains how to build a custom AI Language Tutor using n8n and multimodal LLMs. Learn to orchestrate speech-to-text, ElevenLabs, and Gemini for a high-fidelity learning experience that costs less than 1 euro monthly.
Supply Chain Data Science is set to be the most valuable domain for data scientists in 2026. Beyond the hype of LLMs, the physical world needs visibility and optimization. Learn how to bridge the gap between Python-based mathematical modeling and operational reality using tools like PuLP, Streamlit, and Lean Six Sigma.
WordPress 7.0 development is moving forward with a major decision: officially dropping support for PHP 7.2 and 7.3. Senior developer Ahmad Wael breaks down why this modernization matters for security and performance, explores the new PHP filter extension debate, and shares how to prepare your codebase for the future of WordPress.
The January 2026 WordPress Performance chat revealed major shifts for the upcoming 7.0 release. Highlights include changing Speculative Loading’s default eagerness to “moderate,” resolving Admin View Transition bugs, and fixing modern image format issues in core. Learn how these updates impact your site’s LCP and server load.
Ahmad Wael explores why GraphRAG for Developers is the key to building cost-efficient, high-recall retrieval systems. Moving beyond vanilla RAG, this post covers the importance of data contracts, schema validation in PHP, and production lessons from the December TDS newsletter to ensure your WordPress AI integrations remain stable and scalable.
Stop overengineering your AI. Many developers throw complex RAG pipeline features like query optimization and neighbor expansion at every problem, but the data shows it often isn’t worth the 40% cost increase. Learn when these add-ons actually improve faithfulness and when they just add latency to your WordPress integrations.
Stop fitting straight lines to curved data. This guide explains why Scikit-Learn’s SplineTransformer is superior to polynomial regression for handling non-linear trends. Learn to avoid Runge’s Phenomenon, implement B-spline pipelines, and use periodic extrapolation for cyclical data like seasonal sales or daily demand. Professional advice for building stable, production-ready machine learning models.
