the president of the united states should not be allowed to personally loot the treasury to the sum of ten billion dollars and that this is not resulting in immediate, unanimous impeachment is a dramatic indictment of what has become of our political system

President Trump has filed a lawsuit against the IRS, in which he demands that the IRS, which he as president controls, pay him $10 billion.

Kare 11 local news just read, in full, this statement from Michael and Susan Pretti, the parents of Alex Pretti.

"Please get the truth out about our son."
Statement from Michael and Susan Pretti Parents of Alex Jeffrey Pretti “We are heartbroken but also very angry. Alex was a kindhearted soul who cared deeply for his family and friends and also the American veterans whom he cared for as an ICU nurse at the Minneapolis VA hospital. Alex wanted to make a difference in this world. Unfortunately, he will not be with us to see his impact. I do not throw around the ‘hero’ term lightly. However, his last thought and act was to protect a woman. The sickening lies told about our son by the administration are reprehensible and disgusting. Alex is clearly not holding a gun when attacked by Trump’s murdering and cowardly ICE thugs. He had his phone in his right hand and his empty left hand is raised above his head while trying to protect the woman ICE just pushed down, all while being pepper sprayed. Please get the truth out about our son. He was a good man. Thank you.

I had the most frustrating experience talking to Abercrombie's AI customer service.

It was SO hilariously bad that I decided it deserved its own rant!

Enjoy my pain and suffering!

DID YOU MISS the very first #DataScienceLab when @isabelizimm.bsky.social and @davisvaughan.bsky.social joined us to talk about some of our favorite #Positron settings? Some folks had asked so I wanted to share!

It's up on YouTube here: youtu.be/QIYyeuZ_ISY

I sent 200 pull requests using Claude Code and wrote about the experience. It's pretty wild!

For dplyr releases, we send a PR any time we break an #rstats package. This release advances a lot of deprecated functions, triggering issues in many old packages!

It’s not about drugs. If it was, Trump wouldn’t have pardoned one of the largest narco traffickers in the world last month.

It’s about oil and regime change.

And they need a trial now to pretend that it isn’t. Especially to distract from his sinking under Epstein and skyrocketing healthcare costs.

I'm happy to announce arborium, a collection of 96 tree-sitter grammars (so far) that compile cleanly as crates and npm packages, for desktop & wasm.

It comes with themes, two rustdoc integrations, a clean HTML+ANSI highlighter, get it while it's hot:

How lucky am I that these 2 agreed to join me not just at DS Lab to share #Positron settings, but now TODAY @ the Hangout to share about their dev jobs!

Let's be real, we're all Brandon Sanderson #Cosmere nerds, too, that's gonna come up 😂

#rstats Please welcome Jarl, a new R linter.

Jarl is a CLI tool with extensions in VS Code, Positron, and Zed. It can check thousands of lines of R code in milliseconds.

Jarl provides several output formats, a Github Actions workflow, and more.

new #dplyr filtering function who dis 😍 meet filter_out()!

👍 GO PUT A THUMBS UP ON DAVIS'S TIDYUP THINGY ON GITHUB TO SHARE MY ENTHUSIASMMMM!! #rstats #databs

And, you know, provide your thoughts on this newly-proposed function if you have them 😌
A screenshot of code that uses the dplyr function called filter, which is built to include rows, in order to exclude them instead. The result also filters out rows where values are NA, which isn't helpful usually. It then shows the messy code you'd need to use to not exclude those NAs, and compares it to some very clean code using a newly proposed function called filter_out, which does not exclude NAs. Libby has drawn silly illustrations all over this screenshot, like yucky faces for dropping NAs and a smily face saying, "new filtering function?"

We are looking for #rstats community feedback on 3 new dplyr functions!

We're aiming to expand the `filter()` family:

- `filter()` to keep rows
- `filter_out()` to drop rows
- `when_any()` and `when_all()` as modifiers

Read more and leave feedback here:

TOMORROW, I'm hosting what I'm calling Data Science Lab. This debut session will be our fave Positron settings for #rstats & #python 😍

I called it DS Lounge at first, but that doesn't feel right. You'll see "Lounge" when you register at pos.it/dslab, but future sessions will be "Lab" 🧪😎 #databs

We are extremely excited about this!

@lionelhenry.bsky.social did an awesome job shepherding this feature, and we think that both decimal alignment and using commas as "column guides" for your `tribble()` calls makes QC-ing your code easier and less error prone!
lionelhenry.bsky.social Lionel Henry @lionelhenry.bsky.social · Oct 21
I'm excited to share a new version of the Air formatter for #rstats, with support for tabular formatting! Super useful with `tibble::tribble()` calls or `data.table::fcase()`.

It's currently experimental as we're looking to get feedback on the feature, so please let us know what you think.

Just added Air to the Arrow CI jobs 🪂

It's an R formatter written in Rust, and so fast I genuinely had a "wtf?!" moment the first time I used it.

Would love to see a similar linter; if I had the time, I'd love to try building one - need to get acquainted with tree-sitters one day! 🌳
