Firmino @firmino.work · 13/07/2026Though I tend to run tests locally with cache disabled (flag -count=1), I see it being rather useful on large codebases. 010
Firmino @firmino.work · 09/07/2026> Zig may lose some traction with people Time will tell, but from what I have seen, Zig managed to capture some attention while Rust was on the rise, and from my understanding, some Rust programmers don't find the LLM-based rewrite that impressive. I think that in the long term Zig will thrive. 110
Firmino @firmino.work · 09/07/2026Well done! Any gotchas during the implementation that are worth sharing? 000

Firmino @firmino.work · 08/08/2025Depending on the subject, I then ask the LLM to generate a couple of exercises for me. In the case highlighted on the screenshot, I provided a database schema in a markdown file, and asked the LLM to generate exercises about Postgres Isolation Levels. 000
Firmino @firmino.work · 08/08/2025Not too long ago I started doing something similar. I feed the LLM a url or a pdf, and then ask it to generate a questionnaire. It's easier for me to ingest content about a subject by having in mind a couple of questions about said subject. I haven't yet dealt with hallucinations. 10/10 100

Firmino @firmino.work · 24/01/2025Despite writing software using Go, over time I became less bothered by such superfluous comparisons because they tend to come from new comers, who have not ridden other hype cycles such as the one I rode back in 2013~2014: Node.js vs Java.

Firmino @firmino.work · 30/12/2024Node.js (Express.js or Nest.js) might be a good candidate if you want to launch fast. Go is a good alternative, Rust seems like an overkill but if your goal is to learn, then pick the one you like. 110
