I love you Poland, your people, your culture, I'm sorry you had to suffer so much during WWII and under the Soviet Union and I'm extremely happy you get to host #rstats UseR 2026

But come on...

folks, please don't submit LLM-generated PRs to open source projects. It makes no sense.

If the maintainers want to use an LLM to fix an issue, they can use Claude or whatnot directly. They don't need you as intermediary, that's just silly.

If they don't want to use LLMs, they have reasons.

Out of curiosity, have you ported any of your packages from R to Julia and how was that like?

{hypertext} is a DSL for building HTML in R.
it's similar to {htmltools}, but with 2 deliberate differences:
- it is *framework-agnostic*
- it has *zero dependencies*

we now have more web frameworks in R than ever before. {hypertext} works with all of them, and independently of them.

You made an insulting and sarcastic comment on work I shared and I responded accordingly.

You then further showed creepy, unhinged behaviour navigating my timeline to "like" dozens of years old posts.

Talk of "emotional"...

Now stop harassing me, stop "liking" my posts, stop following me.

I will admit that liking many of my posts, going as far back as May 2025, and including one with a picture of my wife and I did succeed in making me uneasy...

My instincts were correct: you are a creep.

I see your point, most of the time I choose not to entertain those people.

But I don't think it's bad for the brand: the people I work with are also active in the open source community and also have have to contend with such people, they understand perfectly well where it comes from.

I would criticise your work too but there's nothing there but light wrappers around others' work used by no one else but you.

You are stringing dependencies together and not ever creating anything genuine.

Void of original thought you are in no danger of "reinventing the wheel."

You're a moron, your ignorant comment shows you do not remotely understand what the package does and what a preprocessor is.

In the same vein, someone had already mentioned {dtplyr} in the replies: useless comment.

You had nothing interesting to stay, you should have stayed in your fucking canoe.

GitHub - devOpifex/fassplyr: dplyr to data.table dplyr to data.table. Contribute to devOpifex/fassplyr development by creating an account on GitHub.

This is pretty neat actually; using builder (builder.opifex.org) to translate #rstats {dplyr} code to {data.table} code **at build time** so you get zero overhead.

⚠️ it's an llm-generated POC plugin

What's the overhead of sending data and instructions over to the GPU? How big does my data need to be to see improvements?

I agree, I'm wondering whether it can even be realistically changed though: wouldn't you need a written agreement from everyone who ever contributed?

Might even be more realistic to ship your own R interpreter (if legal again).

nothings2 - Twitch Voxel Friday devstream

If you want some impostor syndrome you can go watch Sean Barrett live code for 8 hours without syntax highlighter (code is black, comments are green), without LSP, no autocomplete or anything mildly convenient.

Happy to release builder: a preprocessor for #rstats.

You get a build step with macros, conditionals, directives, preflight, etc. along with new language features like fstrings, a deconstructor, and more.

I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

shikokuchuo{net}: secretbase: The 40KB Hash Package Streaming cryptographic hashes for R

New post: the design behind secretbase, a 40KB streaming hash package I maintain.

The entire source package is smaller than most hex sticker PNGs.

Hash large objects with constant memory. Powers targets pipelines. Plus CBOR encoding comes to R.
