What is it like to create software in the AI era?

You still start with an idea. Something annoys you, or you see a gap, or you just want a thing to exist that doesn’t. That part hasn’t changed. What has changed is how quickly the idea runs into reality. It’s less “can we build this?” and more “why would anyone care, and how would they even find it?” Models and copilots can spit out code and copy that looks fine on the first pass. The bottleneck ...

RAG Is Failing in Production — Here’s Why (and What I’m Testing Instead)

RAG (Retrieval-Augmented Generation) looks great in demos. But in real-world systems, it often fails in subtle ways. Not because retrieval is bad. But because it lacks something more fundamental. The Problem I Kept Seeing Everything worked fine… until it didn’t. Simple questions? Great. But anything that depended on multiple systems? That’s where things started to break. Exam...

What actually happens when you `git merge --no-ff`

Most developers use git merge without ever thinking about what's happening internally. Then one day they see --no-ff in a team's workflow documentation, Google it, read three Stack Overflow answers, and walk away with a vague sense that "it creates a merge commit or something." This post is the version I wish I'd read earlier. Two diagrams, one clear distinction, and why it actually matters for y...

How are people comparing GPU prices across providers?

I’ve been trying to figure out how to actually compare GPU pricing across different providers and it’s way more inconsistent than I expected. The same GPU can vary a lot depending on region and availability, which makes it hard to know what’s “normal.” This is one of the few things I’ve found so far that at least shows pricing across providers: https://www.mercatus-ai.com/gpu-index Does anyone ...

While this approach works at a small scale, it quickly becomes inefficient as complexity grows. In 2026, companies are increasingly shifting toward AI agents that can not only assist but actually execute workflows end-to-end. ...

Every company today is sitting on a goldmine of conversations. Sales calls, customer support chats, interviews, product feedback sessions these are not just interactions. They are signals. Patterns.
