Remember when people talked about the Winter Olympics and the opening ceremony was a big deal? It was yesterday btw

You rarely hear the word glottal outside the context of stops

It's so cold that soap bubbles freeze then burst, leaving behind frozen skeletons

About a year ago I stumbled across one of the best teaching examples of selection effects ever

Inflation has me constantly thinking "ha ha funny!" before realizing it's not an error

I'm suddenly inspired to launch a suburban mall flower shop called Fleurs du Mall. Who wants in?

fun(?) little webapp to plot daylight length D(t) and D'(t) for anywhere on the globe at any time (t) in the year lalten.org/daylight sanity checks: - reproduce solstices as D'(t) crossing y=0 - equator has flat D(t), D'(t) [cc @dggoldst.bsky.social who frequently posts about D''(t) ]

My kids and I made a cube out of paper and hot glue because it seemed like a very Saturday December 20th thing to do

They make planes so big nowadays

There will soon be proctoring center franchises in which people will take tests, do job interviews, and complete paid surveys without access to AI. They'll be strategically placed so that most people will live within a short distance of a proctoring center.

Returning from Bielefeld. Pretty sure, but not positive, it exists.

Back in Germany after many years and the express train is 18 minutes late. So this is how it ends.

The original post above is missing a question mark. At least you know it wasn't AI generated!

A classmate of my 11-year-old daughter said he'd give her a pack of Sour Patch Kids if she could get his pedometer to 67,000. Enter the reciprocating saw.

In 2020, my friend @jasndoc.bsky.social wrote a fictional dialog between R and STATA. In 2023 I said in a few years AI could make it into a stunning movie with spoken parts. It's here. sora.chatgpt.com/p/s_692d0b8c...

Tom Stoppard always made me think. This quote above all.

It's the holidays and our 11-year-old is making her little cousins play the prisoners' dilemma

electoral districts should be determined by an algorithm with proven guarantees and it is cruel not to let the theoretical computer scientists design it because they have been waiting their whole lives for an opportunity like this

There's a joke in Germany that Bielefeld doesn't exist. I have evidence that it may not be a joke after all.

I don't usually fly Delta but when I do I wonder if it's called that because the flight is the delta between you and your destination

The Delta airlines boarding song is Despacito, which literally means slowly and is not how you want people to board a plane

So cool to see a bunch of present and past Microsoft Research NYC researchers' work in this keynote address

Before #MSFT offered "Facilitator" in Teams meetings, @dggoldst.bsky.social et al. developed something similar. People preferred their #statusQuo, but #AI facilitation - made people more open to both human and #LLM facilitation. - didn't seem to impact decisions More via doi.org/10.48550/arX...

Every hotel lamp should have three switches. The switch locations should be determined by pretests conducted in dark rooms. Each switch should reverse the light's state, independent of the other two switch positions.

Every time I come to Denver I can't believe how much space they have. It's like they took a city and scaled up all the streets and distances 150%.

Every few years I feel compelled to post about the best hotel hack ever, because every time I post about it, it turns out to be new to lots of folks …
