<p>(Disclosure: I work on <a href="https://quarto.org" rel="nofollow">https://quarto.org</a>, for the same company that the author of WebR works on) Thanks for sharing that PDF link. It's so good! Would you be willing to write a bit about how you produced that PDF? It's a great example of what places like CIDR should be encouraging in terms of academic publications.</p>

<p>(FWIW, I'm the technical lead on the Quarto project)<p>RMarkdown isn't going anywhere! Quarto exists to bring the RMarkdown experience that folks love to a broader set of users and contexts. It is true that we try to keep the .qmd experience in Quarto pretty close to the .rmd experience in RMarkdown, and it is true that Quarto does things that RMarkdown never will. But it's not the case that "RMarkdown is being phased out and replaced with Quarto".</p>

<p>This is the kind of task that LLMs are precisely terrible at; there isn't an abundance of Zod 4 examples, and the LLM will sure as shit will give you _something_ you are now by definition ill-equipped to assess.<p>I'm confident about this assessment because I maintain a large-ish piece of software and perenially have to decipher user reports of hallucinated LLM syntax for new features.</p>

<p>(I imagine you agree, so this is just to expand) a secondary, insidious issue is that administrators diffuse their rules through the bureaucracy. In the case of CS, you start seeing references to csrankings in recommendation letters for grad applications, faculty applications, or even tenure letters. At that point, it can be hard to fight against it.</p>

<p>(Context: I’m an IC and told my
Manager multiple times that I’d quit if they ever make me a manager)<p>If you truly believe that, please do yourself a favor and read “The tyranny of structurelessness” to understand what a managerless place becomes. <i>everyone</i> and no one becomes a manager, and there’s no explicit avenue of recourse. There’s a good reason management arises. We can discuss good management vs bad management, but pretty fundamentally there’s no such thing as “no management”.</p>

<p>My understanding is that "weird" unicode code points become <a href="https://en.wikipedia.org/wiki/Punycode" rel="nofollow">https://en.wikipedia.org/wiki/Punycode</a>. I used the 󠅘󠅕󠅜󠅜󠅟 (copy-pasted from the post, presumably with the payload in it) to type a fake domain into Chrome, and the Punycode I got appeared to not have any of the encoding bits.<p>However, I then pasted the emoji into the _query_ part of a URL. I pointed it to my own website, and sure enough, I can definitely see the payload in the nginx logs. Yikes.<p>Edit: I pasted the very same Emoji that 'paulgb used in their post before the parenthetical in the first paragraph, but it seems HN scrubs those from comments.</p>

<p>(Disclosure: I’m a former academic with more than a handful of papers to my name)<p>The parent comment is harshly criticizing (fairly, in my view) a <i>paper</i>, and not the authors. Smart people can write foolish things (ask me how I know). It’s good, actually, to call out foolishness, especially in a concrete way as the parent comment does. We do ourselves no favors by being unkind to each other. But we also do ourselves no favors by being unnecessarily kind to <i>bad work</i>. It’s important to keep perspective.</p>
