Lessons handpicked for the Coder shelf.
Claude Code isn't just a coding assistant — it's a general agent runtime with MCP, subagents, hooks, and skills. Treat it that way and you get a free, powerful platform.
The AI coding tool market fragmented fast. Let's map the 2026 landscape honestly: who is for autocomplete, who is for agents, who wins on cost, and what the tradeoffs actually feel like.
AI app builders turn a prompt into a running app in minutes. Learn the strengths, the ceilings, and the moment you should eject to a real IDE.
Databricks Assistant, Snowflake Cortex, and dbt Copilot draft pipelines in minutes. The edge is in modeling, governance, and knowing what business question to answer.
Fresh Coder lessons added to the library.
AI writes Java for you faster than your teacher can say 'Scanner'. Using it without cheating yourself out of the class is the real skill.
Red-teamers try to make models misbehave before bad actors do. Here is how the job works, who does it, and what they look for.
A research preview posted on a Wednesday became the fastest-growing consumer product in history.
The imitation game became famous, but most AI researchers now think it measures the wrong thing.

Fusion generative design explores millions of topology options. nTopology and Ansys simulate in hours what used to take weeks. The ME still owns manufacturability.
The UK stood up the world's first government AI safety institute in November 2023. Its structure, scope, and access model are templates other nations are following.
While larger countries debate, Singapore shipped a practical tool. AI Verify is a testing framework and toolkit that lets companies self-assess against international principles.
Cursor forked VS Code and rebuilt it around AI. It's now the de facto AI IDE for serious engineers. Deep dive on what makes it different, the Composer agent, and the $500/month enterprise pricing.
Windsurf (from Codeium, acquired by OpenAI in 2025) competes with Cursor via Cascade, its autonomous agent. Deep look at where it's ahead, where it's behind, and the post-acquisition future.
AI-assisted coding is not magic and not cheating. It is a new way of working where a model drafts, you decide. Let's draw a map before we start building.
Let's actually feel what autocomplete is like. Write a comment, pause, and watch a full function appear. Then learn what to do next.
A prompt that writes a poem is not the same as a prompt that ships working code. Code has hidden standards. You need to make them explicit.
The AI will hand you code that looks right but isn't. Here are the most common bugs and the habits that catch them before they bite.
Bugs are where AI is most useful and most humbling. Paste errors, ask for causes, run experiments, and learn how to get a real answer instead of a guess.
Writing a test first is not just good engineering. It is the clearest possible prompt for an AI. Let's use tests to make AI code reliable.
Most of a developer's life is reading code someone else wrote. AI is astonishing at this. Here's how to get fast, honest explanations of unfamiliar code.
Refactoring means changing code without changing behavior. That used to be scary. With tests and AI together, it becomes routine.
Time to get hands on. Install a real AI coding editor, sign in, and write your first line together. No credit card required to start.
