Show HN: I built a toy TPU that can do inference and training on the XOR problem

news.ycombinator.com Unknown 2025-11-12 17:52:14

Nobody really understands how TPUs work…and neither do we! So we wanted to make this because we wanted to take a shot and try to guess how it works–from the perspective of complete novices! We wanted to do something very challenging to prove to ourselves that we can do anything we put our mind to. The reasoning for why we chose to build a TPU specifically is fairly simple: None of us have real professional experience in hardware design, which, in a way, made the TPU even more appealing since w

The End of Handwriting

wired.com Angela Watercutter 2025-11-14 18:00:00

People often credit my good handwriting to my Catholic school education—like a nun with a ruler and a taste for corporal punishment perfected my penmanship. But that’s not why. It’s because of my mom. An engineer by trade, she can execute the kind of perfect block letters that only come with years of working on a drawing board. As a kid, I worked to mimic her print as well as her incredibly ornate cursive. I don’t practice those skills nearly enough as an adult, though: As a reporter, speed trum
