The tone of your comment is pretty inappropriate. The whole point of this is to help people learn about DNS, including the author, who happens to be one of the most humble and helpful persons on the internet.

No volume of books can be adequately substituted for doing something, which this project enables handily.

I'm sure you'll be down voted to oblivion but maybe consider a more constructive approach, like opening a PR and helping the authors out.

Note that this sentence was about browser-based integration tests. Browser automation has come a long way, but even on very frontend-fluent teams I've been on we had a few flakey tests, and browser-based integration tests are sometimes flakey in ways that are difficult and tedious to debug! Not understanding why doesn't necessarily indicate any lack of understanding of DNS.

But maybe it increases the odds of a "Let's understand Playwright!" post in the future!

Someone is missing knowledge, admits it, and this somehow inflames you? They created a free tool. Nowhere do they claim that this is a comprehensive replacement of a full O'Reilly book.

I don't really agree with the tone of your comment, and why would you cite a section of the article where the author was talking about a front-end testing framework?

Great job reading the article: she's talking about frontend E2E testing which literally has nothing to do w/ the mechanics of DNS. Every one of these frameworks I've used _is_ a bit flaky too, so this should be completely unsurprising to anyone who actually knows anything about this.

Some of my fondest memories were learning programming and then infrastructure engineering in bits and pieces while so many “veterans” at the time pissed and moaned about how the One True Way to learn was reading O’Reilly books.

A decade into my career, I’m pretty sure I out-earn nearly all of them despite them having a solid decade on me. Of course, income is a fallible indicator, and to the extent that it’s accurate, I don’t think the difference is “reading books vs Googling” but rather (if I had to guess) some handicap that correlates with bitching about how other people learn on the Internet.

life is too short for that.

it is incredible valuable to have a basic understanding of many things. Julia just built a tool which will help me learn the basics of DNS in 20min.
