What happens when you mandate masks at a conference now that most people no longer wear them but medically vulnerable people are still at risk because #CovidIsNotOver? In the case of #PyConUS, the conference sells out.

Why a masking policy? “Many of us and our fellow community members can’t attend without health and safety guidelines in place. We want PyCon US to be an event that everyone feels safe attending,” organizers explained.

Well done @pycon https://fosstodon.org/@pycon/112445571644276379

File import/export in R is simple and elegant with the {rio} #rstats 📦. It uses just 2 main functions for dozens of file types: import() and export(). Whether .zip, .xlsx, Google sheets, json, .rds, .csv or more, rio handles file-extension checks and selecting the right functions.

There's also a convert() function.
One of my favorite R packages!

#Climate threat not often discussed:
“Pound for pound, gallon for gallon, hour-for-hour, the two-stroke gas powered engines in leaf blowers and similar equipment are vastly the dirtiest and most polluting kind of machinery still in legal use.

“According to the California Air Resources Board (CARB), the two-stroke leaf blowers and similar equipment in the state produce more ozone pollution than all of California’s tens of millions of cars, combined.”

Former Amazon VP Ben Smith on admitting he was wrong to push for workers to return to the office several days a week: “As someone once asked me, ‘Have you ever noticed the only people in favor of RTO are people with large admin staffs and grown children?’ I had not, because that was me. Touche.”

Massachusetts State Senate President Karen Spilka: “With Elon Musk’s endorsement of a monstrous and dangerous antisemitic lie, I can no longer justify using the X platform for any reason.I can be found on Facebook, Instagram, Threads and LinkedIn, as can the Massachusetts State Senate. I hope you will follow me, and the Senate, on these platforms, and join us in leaving X.”
But not on Mastodon. Sigh. I'll try contacting her office next week to see if I might persuade them 😃

The {progressr} #rstats 📦 “provides a minimal API for reporting progress updates in R. . . .What type of progress to signal is controlled by the developer. How these progress updates are rendered is controlled by the end user. For instance, some users may prefer visual feedback such as a horizontal progress bar in the terminal, whereas others may prefer auditory feedback.”

The {document} #rstats 📦 creates roxygen2-style documentation for functions that aren't (yet) part of an R package.

In the screenshot below, top left shows a test.R file with a function called test_function , including roxygen definitions. After running

I can use

?test_function

to read the help file as if it were part of a package.

100% agree with this. Generative AI technology will absolutely transform the way people consume and share information. It will cause fundamental shifts in the workplace, and not all in ways we can predict. But don’t expect it all to happen this year or next!
Transformative technologies take time to work their way through society (and the economy). They always have.

Wondering who's here on Mastodon posting about R? I made myself a tool to see who's posted multiple times with the #rstats hashtag in the past month or so, and I'm happy to share it:

Any accounts with nobot or nobots in their profiles have been removed, as have people on instances where the admin has asked me not to scrape. If you otherwise want off, let me know.

“If you last checked in on AI a few months ago, you might be surprised at how much the quality of the output has improved. While there are still errors and hallucinations, they are increasingly subtle and rare, and the quality of even first draft output has improved tremendously. It isn’t as good as good human work, but it is surprisingly capable.AI use is becoming normalized. And I think many people are not ready for what happens next.” - Ethan Mollick

Of course the airline is liable if a chatbot gives customers bad information - the same as if an employee sticks a lower price on an item by mistake, or a sale sign is posted too early, or a price scanner makes an error. Arguing otherwise is ridiculous.
Better testing pre-deployment might have helped prevent this, but there's no guarantee. LLMs may not be human, but they can be unpredictable and imperfect.
