Testing

I Spent 6 Months Watching AI Write Code. The Real Work Wasn’t What I Expected.

AI is transforming coding, but the real skill shift isn’t about writing faster codeβ€”it’s about writing stricter tests. A lone automation engineer reveals the new job description: direct the AI by building test suites so tight that the AI has no choice but to produce perfect code. The developers who survive will be those who master specification, not implementation.

Your AI Code Agent Is Lying to You. Here’s the Only Way to Trust It.

AI agents are writing code faster than ever, but that speed comes with a hidden cost: context loss. The real bottleneck isn’t implementation β€” it’s trustworthy verification. The solution isn’t more reviews; it’s using TDD as a forcing function. Write the failing test first, let the agent earn your trust. Or risk deploying code that passes CI but fails your users.

You’re Wrong About Used EV Batteries: The Real Problem Isn’t Degradation β€” It’s Trust

Used LFP cells are cheap, but they’re worthless without trust. The real bottleneck isn’t degradation or chemistry β€” it’s verifying thousands of cells cheaply at scale. The winner in battery reuse will be the one who industrializes trust through automation and data. Tinkerers and off-grid builders, take note: your project will fail if you skip the testing infrastructure.

Everything You Trust Is Held Together by People You’ve Never Met

Reliability isn’t a natural property of good design β€” it’s a fragile miracle held together by test engineers you’ve never heard of. When they succeed, nothing happens. When they fail, people die. This is the story of the invisible profession that keeps everything from breaking, and why the gap between perceived and actual reliability is getting dangerously wide.

I Spent a Week Building an AI Knowledge Base for a Real Business. Here’s What Went Wrong.

A knowledge base AI takes 10 minutes to buildβ€”but making it actually useful for a business takes a week of non-technical work. Data cleaning, requirement scoping, user testing, and feedback classification are the real barriers. The most valuable work in an AI project has nothing to do with AI.

The Man Who Wrote ‘Clean Code’ Refuses to Read Code. That’s the Future.

Robert Martin, author of ‘Clean Code,’ now refuses to read AI-generated code. He surrounds his agents with extreme constraints and tests instead. This signals a radical shift: future developers will be constraint engineers, not code craftsmen. The most valuable skill is defining gauntlets that code must survive, not writing elegant lines.

Stop Writing Brittle Bash Scripts. Treat Your Terminal Like an API Instead.

Bash scripts are the duct tape of the development world – they work until they don’t. Terminal Control turns the chaotic, stateful terminal into a programmable, observable API, making CLI interactions as deterministic and testable as web endpoints. Stop hacking together fragile scripts and start controlling your terminal with the same rigor you’d apply to any other API.

Your Database Is Lying to You: Why MySQL and MariaDB Are Not Interchangeable

MySQL and MariaDB may share a lineage, but automated stress testing reveals critical differences in transaction semantics that can silently corrupt data under concurrency. Most teams test feature compatibility but ignore how isolation levels and deadlock handling diverge. This article explains the Hermitage project’s findings and why ‘drop-in replacement’ is a dangerous myth.
