- A moiré-mask optical position-encoder concept with interactive animations was shared, illustrating a high-resolution, low-cost method for precise angular or linear sensing (https://docs.switzernet.com/people/emin-gabrielyan/070804-multi-ring-moire-indicator/).

- Participants discussed the 19 July 2024 global Windows outage caused by a faulty CrowdStrike kernel driver update, debating whether it was a hack or an “incompetence / reach-exceeding-grasp” incident and noting that similar kernel panics had already appeared on Linux two months earlier.

- Anna’s Archive lost its .gs domain after being blocked by ISPs in several countries and sued in the U.S. for scraping OCLC’s WorldCat database; contributors criticized OCLC for abandoning its original non-profit, library-commons mission (https://torrentfreak.com/annas-archive-loses-gs-domain-name-but-remains-resilient-240718/).

- A new study in zebrafish regeneration was highlighted, showing that interleukin-11 (IL-11) is critical for tissue regrowth; participants speculated that tightly controlled up- or down-regulation of IL-11 may be necessary for future regenerative medicine applications (https://www.science.org/doi/10.1126/sciadv.abg6497).
