OSM has three routing engines - OSRM, Valhalla, and GraphHopper. For this particular bit of local terrain, only Valhalla gets it right (this routes over bicycle lanes and then cuts through a parking lot). The other two put you through death-defying traffic. 😬

"Cryptophasia" ...

... is when two twins develop a shared, idiosyncratic language that only they can speak

Apparently 40% of all twins create one ...

... most of which remain small in vocabulary, and die out as they age

These guys? They kept going -- and now regularly speak their own language as adults, evolving it and adding new words (for "ipad", etc) as needed

Extremely proud to be working on this.

Remember those German academics who developed a fraud detector that actually did nothing but look at whether the authors used institutional email addresses, had international collaborators, and were affiliated with a hospital?

And then they concluded, based on this "detector", that a high fraction of the papers out of Asia and the Global South are fraudulent?

And then they got a glowing writeup in Science?

(If you missed it: https://fediscience.org/@ct_bergstrom/110357259338364341)

Turns out there's data on all this.

Did you hear about the Origami Channel?

It was paper-view.

But they folded.

Because they weren't willing to make any cuts.
