- Magnonics was introduced as an emerging sub-field of modern magnetism and solid-state physics that studies the intersection of wave phenomena and magnetism, with the Wikipedia entry https://en.wikipedia.org/wiki/Magnonics serving as the primary reference.  
- Participants noted that the Internet Archive (archive.org) now requires JavaScript even for basic searches, prompting discussion of alternative command-line or non-JS clients that had been mentioned on Hacker News.  
- A workaround for the Archive’s JavaScript requirement was shared: specifying an exact year in the URL instead of a wildcard can still return the closest matching snapshot, preserving non-JS access to historical documents.
