OpenAI, Anthropic, Cursor, and Perplexity chose WorkOS over building it themselves.
My thanks to Square for sponsoring this week’s DF RSS. The entirety of their ad text: “Start taking 💸 with the In-App Payments SDK for iOS in less ⏰ than it takes to make ☕️.”.
They’re promoting a short, smart 4-minute video showing just how easy it is to use Square’s In-App Payments SDK for iOS.
For your weekend reading enjoyment, I highly recommend this recent New Yorker profile of Eira Thomas, co-founder and CEO of diamond-mining upstart Lucara, which has developed a knack for discovering particularly large stones:
Gren Thomas dismissed the idea that Lucara had been lucky. His daughter, he said, was both a workaholic and a rigorous scientist. Although it was “beyond anyone’s dreams” that the biggest diamond since the Cullinan would be discovered at Karowe, he felt that Eira had an unteachable talent for discovery. “She has a good smell for things that are liable to be successful,” Gren told me. “She has a good nose, as they say in our business.”
The whole story is fascinating: from the security of modern diamond mines to the history of the marketing that keeps diamond prices high. And, just a week after publication, Lucara found another very large diamond.
