Hacker News with Generative AI: Code Quality

Ask HN: Teams using AI – how do you prevent it from breaking your codebase? (ycombinator.com)
For teams actively using AI coding assistants (Copilot, Cursor, Windsurf, etc.), I'm noticing a frustrating pattern: the more complex your codebase, the more time developers spend preventing AI from breaking things.

Interview gone wrong (ashu1461.com)
I have a very basic question which I usually ask in a interview which is to implement a tic tac toe game. I like this because the logic is straightforward and it helps to judge things like code quality / speed / conciseness etc.

Code Quality at Scale with AST Grep and LLMs (coderabbit.ai)
Smart teams embrace coding standards; smarter teams make them a habit. Coding standards often take a backseat to tight deadlines and pressure to ship features quickly. However, neglecting coding standards lead to a host of problems down the road, affecting code maintainability and increased bug rates.

Accumulated Test Vectors (filippo.io)
I like tests. I especially like reusable test vector libraries. Sometimes test vectors are lovingly handcrafted to target obscure edge-cases. Those vectors belong in Wycheproof or with the upstream specification. Sometimes though vectors are produced by sheer brute force. Enumerate every possible input and check the output. Try a million random inputs and see what happens. Combine all possible input sizes for every parameter. Make one very, very large input.
