40 years ago Steve Jobs built the future on a NeXT box, never knowing his work would shape every app we touch today – from object‑oriented code to drag‑and‑drop. Geoffrey Cain (Steve Jobs in Exile) breaks down that hidden legacy. Watch the short: https://youtube.com/shorts/vnqxatJagbg #SteveJobs #NeXT #TechHistory #ObjectOrientedProgramming

To my niece, and sister,

This book, "12 Bytes," is by one of my favorite authors, Jeanette Winterson.

This book tells us where we come from.
And possibly where we are going.

Her writing is, well, specific. Listen in
full every word, phrase, sentence, and
paragraph. (OK, you can skip the sex dolls article. It is disgusting.)

Jeanette Winterson's sources are well researched and accurate.

Why can't a fiction writer expound on the history, great and flawed, and movement of computing. I, myself, lived through and survived, with bruises, from 1979 through 2018 to today. I think it takes the mind of a fiction writer to comprehend the competing messages.

I also recommend that you read Mary Shelley's "Frankenstein" to absorb references to Mary Shelley, if you haven't already. "Frankenstein" is particularly pertinent to perspectives on AI themes.

John Tukey the Fast Fourier Transform (FFT) inventor, who coined both "bit" and "software" died exactly 26 years ago today.

The Fast Fourier Transform (FFT), one of the most important algorithms in signal processing and data analysis, was introduced by Tukey & Cooley in 1965.

In 1805, Gauss - studying the orbits of asteroids Pallas and Juno - came up with a method to interpolate their trajectories from discrete samples. What he came up with was mathematically very close to the modern FFT but Gauss never published that work, and didn’t analyze its computational complexity. It predated even Fourier’s 1822 work on heat diffusion - but without the framing or generalization that Cooley & Tukey would bring 160 years later.

In 1965, Cooley & Tukey published their now-famous algorithm that reduced the cost of computing a Discrete Fourier Transform from 𝑂(𝑛²) to 𝑂(𝑛 log⁡𝑛). This leap made real-time signal processing and digital media compression feasible.

From radio telescopes to JPEGs, from audio codecs to quantum mechanics - the FFT is everywhere. It’s one of the most important (and elegant) algorithms of the 20th century - rooted in the genius of Gauss, but brought to life in the computer age.
