>I really like the Chris Seaton callout
I miss him. And I really hope someday TruffleRuby will succeed and become mainstream or at least 2nd only to Cruby.

I miss him too. We knew each other online for some time, but that was the first time I ever met him in person. I came back and couldn’t stop talking about him to my wife when she asked how the conf went. Truly an inspiring experience.
I hope truffle ruby does well, too. But even if it doesn’t, he’s still made an impact on me, and on the community. I told him “thank you” to his face when we met. I also wish I could have also somehow let him know my thanks and appreciation was unconditional.

As historical background information, MMTk was initially implemented in Java, and used on the JikesRVM VM, one of the very first bootstraped Java implementations.

Eventually they rewrote it in Rust,
https://www.mmtk.io/
Thus it is much more than the 5 years mentioned on the post, that only covers the rewrite.

> One of the superpowers of MMTk is that it supports parallelism in the garbage collector. Unlike Ruby’s default garbage collector
Wow
Wow
"Wow" as in "why doesn't Ruby have that already" or as in "parallelism will be great"? :-)
Open Source contributors and maintainers feel that there is a constant pressure to be producing. That somehow our worth is somehow only as good as our recent patches. That note says to me: that’s not the case. That even after the contributions stop, or we do, that our efforts and impacts are felt and remembered.
