TokyoR enjoyed the world premiere of mizu today, and Mizu-chan stole the show: lock-free shared-memory parallelism for R, plus a Python binding on the same C core. Repos are open but pre-release, and the API will change. Feedback welcome on GitHub. github.com/shikokuchuo/... #RStats #Tidyverse

Not the least bit surprising but still extremely grim to read. time.com/article/2026...
Since returning to office, Trump has marveled at AI’s capabilities. He is increasingly in thrall to the tech executives courting him. In December 2025, Elon Musk returned to the Oval Office for a clandestine meeting. Trump spent hours asking Grok, Musk’s AI chatbot, questions about his presidency and legacy, according to an official present. At the time, Trump was ordering missile strikes against Venezuelan boats he alleged were smuggling drugs into the U.S. He asked Grok how Venezuelans would react if the U.S. captured Maduro. According to the official present, the chatbot responded that Maduro was a repressive and deeply unpopular dictator and that many Venezuelans would likely celebrate his downfall. After Trump ordered the mission to seize Maduro, the following month, celebrations broke out in the streets. Trump, according to officials, came away thinking Grok was ingenious.

The weird thing about growing up on "twitter is for shitposting and dog photos"-internet is that you still don't use your real name prominently a decade later but then you become an academic and the nice journal folks can't tag you in your publication. Anyway: I did a science! It was fun 😌 #rstats

For context: I used batchtools for every main project in my dissertation and for most of the sidequest projects on a total of 4 HPC clusters and at least 4 shared workstations. I started doing issue triage because now that I don't have to write a thesis anymore I can just... do that. #rstats

Heads up. Don't submit to CRAN right now. The CRAN submission system is currently broken, because Windows checks won't complete. If you submit your package will end up in the manual "inspection" queue. You'll see the same on win-builder R devel and R 4.6.1. The R 4.5.3 still works. #RStats

Yesterday, we released a new version of anvl: github.com/r-xla/anvl. You can use it to implement numerical algorithms in R and run it on CPU and GPU. The R Code is compiled, so you do not have interpreter overhead, and it also allows you to automatically compute gradients #rstats

It is no coincidence that rationalists and EAs tend to be straight white guys from well-off families, because for everybody else, the world usually conspires to knock some sense into you about your inherent god-emperor genius by the time you’re old enough to drink.

the Eliezer Yudkowsky superhero origin story is truly so intensely dorky as to defy all attempts at parody. you could not waterboard any of this out of me web.archive.org/web/20010309...
His autobiography even opens with a parable: as a small child he threw his favorite squirtgun off a third-floor balcony rather than accept that his mother could lend out what was his, and felt complete when he heard it hit the pavement. He goes on to describes himself as a specialist in the technological transformation of the human species, one of the few people alive with the standing to steer it. He identifies with Buffy the Vampire Slayer, the one person who sees the danger clearly and has to act while everyone else gets on with ordinary life.

I’m helping colleagues with DB access stuff via #Positron in both #rstats and Python. In R I can point them to the keyring pkg to store their DB pw and user so they don’t hardcode credentials in scripts, there surely is a comparable solution in Pytjon, right? Want to avoid interactive prompts.

Survey of German academics finds restrictions on academic freedom are rare and not associated with academic position, discipline or gender, but expectations of restrictions are higher among precarious academics. Hope this paper gets attention, as it does not confirm media stereotypes of academia

Pen, watercolor, black & white charcoal pencil.

Another featured piece from the Spooky Pants book.

A man in a sweater stands with his hands on his hips looking out of a large window with the curtains open. Things aren’t looking good outside, reader. A massive winged demon is emerging from the clouds as dozens of little ghosts and bone demons rip through the sky. On the ground below we see townsfolk running through the grass. Our man in the window is in no mood for this. He lets us know, “Oh, I am in no mood for this.” His dog looks out the window as well, wagging its tail. 

Fantasia (1940) inspired drawing. I think I could’ve gone a little heavier with the chaos outside but we’ll try again with fresh drawings this October. I like how the clouds turned out. Trying to balance my sloppy lines with more detail can be tricky but I think we achieved a good result.

Anthropic's models run on terabytes of VRAM. It's not going to "just copy itself to other computers."

@rohanpaul_ai
Jacob Coxon's next interview on CBS News (ex Anthropic+Open AI researcher who resigned)

"We can't just unplug it because it could be copying itself over to other computers. Like it's not that difficult to find yourself because an AI is just code. It could transfer itself over the internet to a different place and then you unplug it here, but it's actually still over there and maybe it makes 10,000 copies of itself and they're all cooperating."

Most of my Time Machine backups are broken now and I need to clear the one target drive. Last episode of @atp.fm talked about how APFS is bad at millions of small files or so - this appears to be one of the consequences? TM essentially got stuck enumerating files, producing incomplete backups

PSA if you use #WhatsApp on macOS: Check the size of your ~/Library/Group Containers/group.net.whatsapp.WhatsApp.shared Mine is well over 200GB and has a huge number of small files which most likely is the root cause for why my Time Machine backups have been stalling and not completing for days.
