It's, um, a bit over 12 years since I last went on sabbatical, and though I'm not technically on sabbatical yet, I am about to leave the building. It somehow seems less momentous than last time

I have always loved this paper, and even though I knew about it, I still foolishly bought some cutlery for my departmental tearoom... and we know how that went...
70 teaspoons placed in tearooms around the institute & observed weekly over 5 months. 80% of spoons disappeared; spoon halflife~81 days. Communal room halflife lower than in specific labs. 250 spoons annually required to maintain 70 spoon population.

Filling a new ethics question on data deletion. Tempted to go with the overly honest version: "Even after data deletion, the data will still likely be stored on 15+ servers around the EU and accessible to various of our IT staff for at least 93 days"

I feel like I spend far too much time explaining why prestige journals are not good indicators of quality. So it's no surprise that drivel was published in JAMA
It is the *mentality* reflected in this "score" that is part of the underlying problem, further reflected by the fact that this specific "solution" will only ever exist in a PUBLICATION. It would be better if they implemented this in their own institution and then wrote about why it didn't work.

I've seen so many threads here that were just rage wagons about ML tech unrelated to LLMs that was wholly uncontroversial 5 years ago just because people saw the AI moniker attached.

Not what most people are calling out here, but I think you'll see that those grey circles over with in the North America space are most of the cities in New Zealand and Australia 😭
This is interesting — a recent study of mode share (the % share of transportation trips by car, transit, walking, biking etc) relative to city size and income levels in almost 800 cities in 61 countries. Interesting results. HT @davidzipper.bsky.social

Stumbled across this today. As someone who has tried to improve their garden soil, by adding tandem trailer loads of stuff, and barely adding a few mm, 3 inches across all of the UK is just MASSIVE

This is why I wrote a paper on count regression, and in general am a big proponent of generalised linear models. Almost nothing is 'normal'/gaussian. Days off sick are very obviously a count (whole numbers only, never below zero) doi.org/10.1080/2164...
For instance, yesterday I read a paper with a table describing participants' sickness absence days with a mean of 71 and SD = 88. Generating a random (gaussian) sample using these values produces ~20% participants with less than zero sick days.
