“The Internet We Could Have Had“
Professor Chris Kelty, UCLA
November 4, 3:45 - 5:15 PM, Humanities Quadrangle, room 276Abstract: What was the internet we could have had and how is it related to the one we do? This talk will offer part of a book project on the moral and technical imagination of the internet as a global brain, a new economy, and a participatory democracy, and how it enabled instead an ad-revenue-driven social media hellscape of privacy violation, data extraction, and autocratic monopolies. In particular it will focus on the internet as an era of artificial intelligence, and offer a revision of the place of the internet as part of the technical infrastructure of knowledge and power. What are the implications--for science and politics--of automated data circulation, ennobled by an ethics of sharing, and mystified by the most expensive statistical clustering experiments in history?

There will be a UNIX question, as in the first midterm. Here is a sample UNIX transcript (solutions) UNIX will cover through principle 3.
Review session: Today at 6pm on zoom. Check Ed Discussions for deets and slides.
From Rudy:
You can tell them that I also updated the original message with detailed answers - for those that can't (or don't want to) attend the session.
The version of Python on the zoo is 3.10. That is the version used by this assignment and the autograder. There were some major changes to byte codes in version 3.11, and for that matter, in version 3.9. See dis.html and specify version 3.10.
