It's certainly an interesting choice of name!
Should you say "TRY-no" to rhyme with Rhino or "TREE-no" to rhyme with Arduino?
I would do the latter, but I'm a debauched expat. My guess is that half the people in America will do the former.
Because I overthink this stuff I had to go see what's on trino.com and it's an impressively old-school unfinished personal website.
So we have one vote for tree-no, it's a start! With me, that's two!
Also, if anyone is reading this wondering which version Athena comes from, it's a release that was common to both Presto and Trino before the fork. However, more recently we've worked with the Athena team on getting the newer Trino features that aren't in Presto today in Athena. So it's starting to become more based on Trino.
