Weekly Notes 29/2025

Reading

• The Courage to be Disliked by Ichiro Kishimi and Fumitake Koga (17%)
• The 6:20 Man by David Baldicci (28%)
• A New Horizons First for Interstellar Navigation by Paul Gilster
  • “Mariner 4 used Canopus, a bright star in the constellation Carina, as an attitude reference, its star tracker camera locking onto the star after its Sun sensor had locked onto the Sun. This was the first time a star had been used to provide second axis stabilization, its brightness (second brightest star in the sky) and its position well off the ecliptic making it an ideal referent.”
  • “…we’ve also just had a first in terms of autonomous navigation through the work of the New Horizons team. Without using radio tracking from Earth, the spacecraft has determined its distance and direction by examining images of star fields and the observed parallax effects. Wonderfully, the two stars that the team chose for this calculation were Wolf 359 and Proxima Centauri, two nearby red dwarfs of considerable interest.”
• If You Like Public Broadcasting, Be Customers, Not Just Consumers by Doc Searls
  • “That its consumers are also its customers is a huge advantage over commercial over-the-air broadcasting, which entirely serves the advertising market.”
  • “First, over-the-air broadcasting is in decline, as listening shifts from live radio to podcasts and music streams, while TV shifts from over-the-air and cable (now together called “linear”) to paid on-demand streaming (now increasingly subsidised by advertising as well).”
