Part of a tiling of the hyperbolic plane where 7 equilateral triangles meet at each vertex, wrapped isometrically onto a surface with curvature K=–1:
z = ±ξ |E(arcsin(cosh s) | m)–E(m)|
ρ = √[ξ^2–1] cosh s

E is elliptic integral
ξ is max radius
m = 1–1/ξ^2
s is dist from waist

Temporary moratorium on use of #FacialRecognition tech in state schools is now a matter of law in #NewYork, following the conclusion of study that found potential rights violations outweighed safety benefit. The ban is the result of temporary moratorium placed on facial recognition tech in the state’s K-12 schools issued in December 2020 by former governor Andrew Cuomo. https://www.cpomagazine.com/data-privacy/state-of-new-york-makes-moratorium-on-facial-recognition-technology-in-schools-permanent/ #CivilLiberties Privacy #Suveillance #education #students #legalresearch

@gilles Indeed. So now when a person adds Gmail to Outlook, they have both Google and Microsoft farming their data and training AIs.

We are doing everything in our power within the next year to make Thunderbird a complete end-to-end solution for people who want to escape the Gmail + Outlook ecosystems.

Bidirectional comms to Psyche is now active via NASA DSN.

Uplink power needed is just 200 watts, given the gain of the antenna.

How to observe the October 14th Annular Solar Eclipse. Excellent Sky & Telescope guide by Fred Espenak. #AstroDon #Astronomy #Astro #Space #Astrophotography https://skyandtelescope.org/astronomy-news/observing-octobers-annular-eclipse/

Yesterday I spoke to an MIT sophomore hoping to get an interview for a Google internship. The student has already done one summer internship at another company, enters programming competitions, and has coursework in machine learning, distributed systems, and neuroscience. So far they have submitted over 40 internship applications.🤯

From all their applications, they've only gotten two OAs (online assessments), and no interviews.

It is so much harder for kids today than when we were young.

Learning is not the product of teaching. Learning is the product of the activity of learners.

Psyche (the spacecraft) is headed to Psyche (the asteroid). Not just any asteroid, but a strange, metal-rich one.
It might be the exposed core of a protoplanet that was destroyed billions of years ago. But we won't know for sure until we get there.
Much more info about the mission here:

I've had more opportunities recently to create plots with #SwiftUI / Swift Charts / #Swift playgrounds and the process absolutely holds up in replacing #python / #matplotlib / #jupyter.

The dataset was larger this time, ~100k records, each containing a handful of data points, exported from a Postgres DB as JSON.

Massaging the data in a typesafe way is an absolute blessing – it's so easy to plot the wrong thing in python as you drill through three dicts.

Really happy with the results!

Yay! Take it, Corona!
And thanks to mastodon for helping me find a place in #Münster to get the shot!

You take an arrow to the knee, and you're not an adventurer anymore.

Years later you still limp, but the arrow? Long gone. It did its work in an instant.

This is #LongCovid. You no longer test positive for the virus, but you're not an adventurer anymore.

"Long COVID" does not mean "having COVID for a long time."
It means the virus disabled you.

Yes, that's a thing viruses can do. Don't give this one the chance.

I used to be an adventurer like you, but then I took an arrow to the knee.
