Aaron's Code tells the story of the first profound connection between art and computer technology. Here is the work of Harold Cohen - the renowned abstract painter who, at the height of a celebrated career in the late 1960's, abandoned the international scene of museums and galleries and sequestered himself with the most powerful computers he could get his hands on. What emerged from his long years of solitary struggle is an elaborate computer program that makes drawings autonomously, without human intervention - an electronic apprentice and alter ego called Aaron.

Aaron McDuffie Moore (1863–1923) was born in rural Columbus County in eastern North Carolina at the close of the Civil War. Defying the odds stacked against an African American of this era, he pursued an education, alternating between work on the family farm and attending school. Moore originally dreamed of becoming an educator and attended notable teacher training schools in the state. But later, while at Shaw University, he followed another passion and entered Leonard Medical School. Dr. Moore graduated with honors in 1888 and became the first practicing African American physician in the city of Durham, North Carolina. He went on to establish the Durham Drug Company and the Durham Colored Library; spearhead and run Lincoln Hospital, the city's first secular, freestanding African American hospital; cofound North Carolina Mutual Life Insurance Company; help launch Rosenwald schools for African American children statewide; and foster the development of Durham's Hayti community. Dr. Moore was one-third of the mighty "Triumvirate" alongside John Merrick and C. C. Spaulding, credited with establishing Durham as the capital of the African American middle class in the late nineteenth and early twentieth centuries and founding Durham's famed Black Wall Street. His legacy can still be seen on the city streets and country backroads today, and an examination of his life provides key insights into the history of Durham, the state, and the nation during Reconstruction and the beginning of the Jim Crow Era.

“Blockchains will matter crucially; this book, beautifully and clearly written for a wide audience, powerfully demonstrates how.” —Lawrence Lessig “Attempts to do for blockchain what the likes of Lawrence Lessig and Tim Wu did for the Internet and cyberspace—explain how a new technology will upend the current legal and social order... Blockchain and the Law is not just a theoretical guide. It’s also a moral one.” —Fortune Bitcoin has been hailed as an Internet marvel and decried as the preferred transaction vehicle for criminals. It has left nearly everyone without a computer science degree confused: how do you “mine” money from ones and zeros? The answer lies in a technology called blockchain. A general-purpose tool for creating secure, decentralized, peer-to-peer applications, blockchain technology has been compared to the Internet in both form and impact. Blockchains are being used to create “smart contracts,” to expedite payments, to make financial instruments, to organize the exchange of data and information, and to facilitate interactions between humans and machines. But by cutting out the middlemen, they run the risk of undermining governmental authorities’ ability to supervise activities in banking, commerce, and the law. As this essential book makes clear, the technology cannot be harnessed productively without new rules and new approaches to legal thinking. “If you...don’t ‘get’ crypto, this is the book-length treatment for you.” —Tyler Cowen, Marginal Revolution “De Filippi and Wright stress that because blockchain is essentially autonomous, it is inflexible, which leaves it vulnerable, once it has been set in motion, to the sort of unforeseen consequences that laws and regulations are best able to address.” —James Ryerson, New York Times Book Review
