Code is written for people: Knuth, Guido and the Hitchhiker's Guide on readability

Donald Knuth explains in two conversations why he writes programs as literature through literate programming, Guido van Rossum describes programs as recipes written for two audiences and digs into code readability, and The Hitchhiker's Guide to Python devotes its core chapters to writing and reading great code. Treating the human reader as the main audience changes how programmers name, structure and explain their work, and makes code easier to maintain.

What big tech gives to open source, and what it takes

Mark Zuckerberg and Yann LeCun explain why Meta gives its AI models away, while Jean-Baptiste Kempf and Kieran Kunhya describe how large companies lean on FFmpeg and VLC and add to their maintainers' load. Set side by side, they show the two faces of corporate involvement in open source and why the relationship is not simply generous or exploitative.

Who decides what stays up: Zuckerberg, Wales and Hotz on pressure and control

Mark Zuckerberg and Jimmy Wales describe how Meta and Wikipedia respond when governments push on content and data, and their answers differ because one runs a company with staff and servers and the other a volunteer project with no advertisers. George Hotz, after a short stint inside Twitter, does not discuss government pressure there; his argument is that any single decider, state or owner, is the problem, and that filtering should belong to each user.

Three physicists on cooperation between rivals, from fusion to nuclear restraint

Dennis Whyte shows that rival powers have shared fusion science since the Cold War and still build ITER together, while Carlo Rovelli and Max Tegmark point to the treaties, weapons bans and individual acts of restraint that kept nuclear rivals from destroying each other. Together they argue that cooperation between enemies has a real record, and they are frank about its costs: slow megaprojects and far too much reliance on luck.
