Historical Figures from God Created the Integers
I made some notes about God Created the Integers by Stephen Hawking which I have been reading recently. I’m in the process of creating a new book teardown for it. I needed to make some notes about how to pronounce various names. I didn’t do this until I was half-way through the book though. If I had have taken the time to do this activity sooner I would have embarrassed myself less. Anyway. Better late than never!

Hexing the technical interview meets DALL·E
There is a hilarious quote from Aphyr in Hexing the technical interview:
Vidrun, born of the sea-wind through the spruce
Vidrun, green-tinged offshoot of my bough, joy and burden of my life
Vidrun, fierce and clever, may our clan’s wisdom be yours:
