Discussion

• Nvidia/Intel dual graphics problem
  • Greg answering mailing list report of problem starting chimerax on dual nvidia/intel "prime" graphics.

• Web site accessibility
  • Greg working on resolving some color contrast issues.
  • Tom says 49 chimera tutorial videos with audio should be hidden since we don't currently plan to caption or put on youtube.
  • There are 25 animation videos (5 seconds, no audio) that are fully described in the text. Greg should submit review requests, since no change should be needed.
  • Probably about 15 other short chimerax and chimera animations without audio also described by text need review request.
  • Scooter is working on captioning historical videos (probably fewer than 10).

• ChimeraX Trac database down today
  • Greg will restart mariadb to get Trac working.
  • First he shutsdown Toolshed to avoid error email. Then restart mariadb with pcs restart.
  • Usually that is sufficient to get Trac to work, although sometimes it requires a database restore.
  • Database is saved every night. Also if restore is needed, first try dumping current database.
  • Same mariadb instance used by Toolshed and Trac. Heavy toolshed update queries may be related to Trac breaking.

• Wynton decommissioning meeting
  • Greg had to leave for 3:30 Wynton decommissioning meeting.
