Completely agree. There is a common misunderstanding/misconception in product development, that more features = better product. I’ve never seen a product/project manager questioning themselves: does this feature add any value? Sho

Everything in infrastructure is a set of trade-offs that work in both directions. If you want better monitoring, metrics, availability, orchestration, logging, and so on, you pay for it with time, money, and complexity. If you can't ju

I want to keep this series focused, but LFS-style content is definitely something I'm considering for later, I think it's a good idea. That said, this series will also give you practical, applicable knowledge as we progress.

In the post it is set to 0. `CGO_ENABLED=0 go build -o init .` The only reason is because I like to be explicit, and I could not know what was set before in the user's environment.

The goal was to strip away most of the complexities (including C), to make the topic more approachable for a broader audience. Go seemed a perfect fit, it is easy to pick up the syntax and see what is going on, but you can still be close to

I never claimed this was a scientific study. It was an observation repeated over time. That is empirical in the plain meaning of the word. Criticizing it for “not being scientific” is irrelevant, I didn’t present it as science. Are people o

I did not say that I only ran the prompt once per attempt. When I say that second time it failed it means that I spent hours to restart, clear context, giving hints, everything to help the model to produce something that works.

No one talked about determinism. First it was able to do a task, second time not. It’s not that the implementation details changed.
