I named my group's HPC system "Hermes" after the Greek god. Apparently, some folks thought I named it after the French luxury store "Hermès." To clarify: our HPC system runs on grants, not Birkin bags. I added some flavor text to help clear things up.

Some UW ATMOS grad students performed songs about life as an atmospheric chemist yesterday. -Nosedive by Post Malone about working with analytical instrumentation -Its Fine Its Cool by Chappell Roan about assuming atmospheric OH is constant Several will be at #AGU if you want their autographs

Excited to see folks at #AGU24 this week! Some presentations from my group members. Lots of stuff on Friday this year.

Today I learned that: a) I have a Bluesky account and b) I have friends on aforementioned Bluesky account. I have zero recollection of making this, but thanks for this revelation @reobrien.bsky.social!
