I heartily agree! I love how the structure of contra dancing connects so many people. The local dance community has made the city I live in actually feel like my home now.

The specific moves and calling during the dances make it so easy for beginners to pick it up, but there’s a lot of flair and flourishes that advanced dancers can add to keep things interesting.

Since starting a couple years ago I’ve made so many incredible friends, gone to dance camps, and began calling my own dances! I never expected to be on stage with a microphone but now it almost feels normal to have a hundred people act out the dance moves I give them.

Thank you for taking the time to explain this! I had bookmarked the above comment in the hopes that someone would.

There's a fun way you can try seeing individual photons yourself! With a Nuclear Spinthariscope, somewhat popularized in this XKCD comic https://xkcd.com/2568/

You can buy them for about $50 from some science education sites. It's quite a conversation starter, as long as you're ready to sit in the dark for 15 minutes.

This was a time me and my partner spent far too much effort building contraptions to try and stay cool. Sucking colder air from the apartment hallways, converting a single-hose portable A/C into a dual, and others.

But an especially effective project was an experiment to determine exactly what window covering would reduce heating from direct sunlight the most. We could only cover the inside of windows, and I had assumed aluminum foil would work best, but wasn’t sure.

I set up a test of various materials and stuck them to my window with a thermoprobe and some insulation. I tested printer paper, various foils, and plastics.

Plain old white printer ended up performing the best, and aluminum foil being significantly worse. Best part about paper was it still let a lot of visible light in, while reflecting IR.

Hope this helps someone a summer heats up again!

They actually have this, and I think its intentionally very creepy: https://support.apple.com/library/content/dam/edam/applecare...

Does this book have much relevance for someone already working in an existing engine like Unity?

It was my understanding that iOS devices have kernel or hardware checks prevent unsigned code from running. This is why JIT languages don't work there.

Is that true? If so, how to remote code execution exploits like this work?
