Professional user

There’s a familiar role on a team: tester, test engineer, software quality assurance — someone who tests an application professionally.

But it would be cool to have a professional user: not a professional tester, but someone who uses the product professionally. For example, if a company is building an ecommerce …

A new large language model isn’t always better than the old one

Sometimes it seems (or marketers assure us) that everything new is better than the old stuff.

I’m migrating a translation service that uses language models. The old version uses gpt-4.1, and the new one uses gpt-6-luna. Users complained that the new version was translating more slowly.

I thought: how …

The key mistake in adopting AI — misunderstanding delegation

For example: what I need is a configured, tested, reliable SaaS application. I don’t need ChatGPT for that. I need someone who will take responsibility for the result. Whether they use AI or not is a secondary question.

On code review quality benchmarks, it’s no worse than 80% of senior developers. :)

ChatGPT was writing my letters back in 2013

I have proof that ChatGPT was writing letters for me way back in 2013. :)

Empirical proof that AI doesn’t increase productivity

To avoid wasting your time, let me give an important definition. Productivity is how much money you earn for the time you put in.

If you earn $1,000 in 160 hours without AI, let’s call that your baseline productivity: 1X.

If you earn $5,000 in 160 hours with …

I like reading documentation

I read documentation this week. And last week too. And next week I’ll be reading documentation too. I like reading documentation.
