NixOS and Kagi user here. Hacker News often is the most reliable search result there is. Gists aren’t (they become easily deleted, unlike HN comments).
Sure, and I accept that happily enough for "small" snippets. But I had to page down multiple times and it really felt like too much content.
The chances of people reading this discussion running NixOS are small, and of those I'm sure the ones who were interested could search the internet for examples.
