This article explores how software developers can integrate ChatGPT Codex into their development workflows, from initial code generation to pull request creation. Codex is OpenAI’s code-focused large language model, capable of reading and writing code, generating test cases, and interacting with GitHub repositories. We explain how to get the most out of Codex by combining it with unit tests and test-driven development (TDD), ensuring reliable and verifiable results. Drawing on real-world advice from Simon Willison, we emphasize why automated testing is not just a complement but a critical enabler of safe and effective AI-assisted software engineering.

Beyond the Buzzwords: What Is Machine Learning, Really?
Machine learning is transforming industries, but at its core, it remains a field built on mathematics, logic, and structured data modeling. This article walks through the foundational principles of machine learning, stripping away the modern layers of abstraction to focus on its original essence. No libraries, no black boxes, just math and reasoning. Whether you’re a beginner with a math background or a curious technologist aiming to understand what actually powers intelligent systems, this is a ground-up journey into how machines learn.
The AI Trap: Why Replacing Junior Engineers Might Cost Us the Future
AI is changing how we build software—faster, smarter, and increasingly without junior developers. But replacing entry-level roles with AI may leave us with a future shortage of experienced engineers who understand systems deeply enough to guide that same AI. This post explores why mentoring and experience still matter, and how we can build a sustainable path forward.
From Code to Ownership: The Rise of Ethereum and Solidity in Real-World Applications
Ethereum is more than just a cryptocurrency—it’s a programmable platform that brought the concept of decentralized logic to blockchain technology. Solidity, Ethereum’s primary programming language, is what developers use to build decentralized applications (dApps) and smart contracts. This blog series breaks down how Ethereum and Solidity work, explores why they’re revolutionary technologies, and highlights successful real-world applications from decentralized finance to tokenized real estate.
Beyond Twitter and Bluesky: Building the Social Web We Actually Want with Mastodon
As the cracks in centralized platforms like Twitter (now X) deepen, alternatives like Mastodon and Bluesky are racing to reshape the social internet. But while both offer something new, only one fully commits to the core principles that made the early internet great: decentralization, user ownership, and community-driven governance.
This post unpacks the real differences between Mastodon, Bluesky, and Twitter — and explains why Mastodon isn’t just an alternative. It’s the future we should be rooting for.
