I don’t usually write about security, but as a frequent user of Claude Code, I felt the recent news of the s1ngularity attack warrants special attention. Just as we all started to rely on AI CLI tools like Claude and Gemini to enhance our work, hackers just exploited them in a real supply-chain attack. It’s the first time we’ve seen this in the wild.

I used to spend my time before classes playing the original Desktop Tower Defense. It had a long loading screen, it lagged when there are too many units, and it was written in Flash. I wanted to make a modern JavaScript version that’s smoother and more optimized, but I wasn’t a web developer… until LLMs came along.

I recently build a browser-based javascript game. I have very little JS experience and have learned a lot along the way, both in terms of JS and working with Claude. These are my takeaways.

In the world of modern software development, few libraries have had as transformative an impact as Pydantic. What began as Samuel Colvin’s elegant solution to Python’s data validation challenges has evolved into the foundational layer powering everything from high-performance web APIs to cutting-edge AI applications. Today, Pydantic sits at the center of an ecosystem that has become indispensable for developers building reliable, production-ready systems.

Mocking is tremendously important in unit testing because it isolates the unit under test. Use mocking to prevent unnecessary calls to external resources and control your object behavior to test for edge cases!
