They're being phased out and replaced with Quarto.

(FWIW, I'm the technical lead on the Quarto project)

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".

I’m dismayed that people are willing to put their names on garbage like this.

If you want the serious version of the idea instead of the LLM diarrhea, just go Jonathan Shewchuk’s robust predicates work: https://people.eecs.berkeley.edu/~jrs/papers/robustr.pdf from 1997.

I'm sorry if this has been answered many times in the past. I didn't find the answer anywhere else.

If everyone gets 1000$ extra, why wouldn't rent increase by close to 1000$. If you're not willing to pay it, someone will. I don't understand how giving all of us X amount of dollars would help. The number of goods are the same, they would become more expensive through inflation.

Presumably because one of the two things are true:

- there's competition, and so if it's possible to rent for less than 1000-eps and still profit, someone will

- there's no competition, which is a cartel, the kind of thing that civilized societies ought to frown upon

> For projects that rely heavily on Zod, it feels like a daunting task ahead—one that will demand a lot of developer attention and time to navigate.

Or just use an LLM.

cscheid · 3 months ago
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.

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.

cscheid commented on Reversing the fossilization of computer science conferences   cacm.acm.org/blogcacm/rev... · Posted by u/tosh

A big part of the problem here is that Universities have increasingly begun attaching prestige to specific “top” conference publications for both ranking and faculty promotions. A good example of the phenomenon can be seen in [1] (sorry for the noun-citation!) which only gives credit for approximately three conferences in each field. Combine this with a flood of new researchers entering CS, you have a recipe for “top” conferences being essentially destroyed and filled with uninspired work.

(And contrary to the joke in the article, even your own work becomes uninspired when you ship it to those conferences. You can’t afford to be quirky or interesting.)

Fortunately every field has a fourth or fifth-tier conference that isn’t on this list (or a specialized topic conference that the rankings folks don’t care about), and those still serve the purposes that conferences were made for. You just might not be able to convince a ranking-obsessed administrator that your work has any value if you publish there.

(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.

Here are the primary components that you would require - 1. Organic Matter: Compost and mulch enrich soil and improve structure. 2. Microorganisms: Bacteria, fungi, and mycorrhizae break down organic matter and enhance nutrient uptake. 3. Soil Fauna: Earthworms, insects, and arachnids aerate soil and mix organic matter. 4. Nutrients: Macronutrients (N, P, K) and micronutrients (Fe, Mn, Zn, etc.) are essential for plant growth. 5. Soil Structure: Aggregates and porosity improve aeration and water retention. 6. Water Management: Proper irrigation and drainage ensure optimal soil moisture.

Please - if I wanted to know what an LLM thinks about this, I would have asked it myself.

I'm going to make the observation that politics in a company is caused by management. The more "politics" you have at a company, the more you pay in a "political tax". Effort which should benefit the company is delayed or made harder as employees have to bob and weave to get through the politics.

I do believe if you want real culture change in a company, the best way to do it is to show managers the door, because that's how you got there in the first place.

Edited to add:

I'm not saying get rid of management. I'm saying get rid of bad management. And if your bad management is a malignant tumor, well, it's too late to fix it manager by manager -- because they've internalized how to game the system for themselves.

(Context: I’m an IC and told my Manager multiple times that I’d quit if they ever make me a manager)

If you truly believe that, please do yourself a favor and read “The tyranny of structurelessness” to understand what a managerless place becomes. everyone 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”.

so.... in theory you should be able to create several visually identical links that give access to different resources?

I've always assumed links without any tracking information (unique hash, query params, etc) were safe to click(with regards to my privacy). but if this works for links I may need to revise my strategy regarding how to approach links sent to me.

My understanding is that "weird" unicode code points become https://en.wikipedia.org/wiki/Punycode. 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.

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.

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.

This is not an increase over baseline risk (as its Palermo scale[0] indicates, being a negative number, -0.56).

I think there's going to be a crisis of media going forwards, because with the very awesome new telescope[1] that's going online this year, the number of these detections is going to drastically go up. The number of objects isn't going up—they've always been there, we just didn't know—but I think the media coverage is not going to absorb that nuance very well.

[0] https://en.wikipedia.org/wiki/Palermo_Technical_Impact_Hazar... ("A rating of 0 means the hazard is equivalent to the background hazard (defined as the average risk posed by objects of the same size or larger over the years until the date of the potential impact)")

[1] https://www.technologyreview.com/2025/01/01/1108643/vera-c-r... ("With its capacity to detect faint objects, [Vera] Rubin is expected to increase the number of known asteroids and comets by a factor of 10 to 100")

cscheid · 7 months ago
(I worked tangentially on software for analyzing data that will come from the Vera Rubin telescope, and) yeah, while it was designed for spotting weird supernovae and such, the first half of its operation is expected to be dominated by the discovery of near earth objects.
