Discussion Notes

• Web site accessibility remediation
  • Score is now 97%.
  • 3 potential issues still listed but can be dealt with at our leisure.

• Software export control
  • May need to restrict distribution of ChimeraX to Iran, North Korea, Syria, Cuba, certain regions of Ukraine.
  • UCSF export control office may look at ChimeraX. Interested in encryption technology.
  • Don't have a date when this will happen.

• Restoring historical videos
  • Scooter worked on Cronkite_Singing_Genes.mov.
  • Tried Adobe Premiere. Can apply filters to specific segments (e.g. switch to black and white in b/w segments)
  • Then tried Topaz AI. Processes whole video as one chunk. Used deinterlace and Proteus algorithms.
  • Did second Topaz pass of Theia and NixXL filters.
  • Topaz did not do much better than Premiere.
  • Topaz Pro has Starlight algorithm that might do better, $700.
  • AI algorithms improving. We could get Premiere and Topaz plugin. Or we can wait for better algorithms.
  • Tom Ferrin asks if the original NTSC tapes are still valuable. Scooter says some are, others are not our material. Videos with Bob Langridge are valuable.
  • Scooter will add README file to original clips directory listing the most valuable videos.

• Gestwicki lab post-translational modification web app
  • Wants to present at our group meeting what they have done.
  • Will try to schedule for next Thursday.

• Toolshed caching of update results
  • Greg added caching for one query last night. Not sure if it is the query with heavy load.
  • Scooter says MariaDB still running at 53% cpu utilization.
  • Greg will make sure caching is being used.
