Today is my last day at Meta. This has been the best team I’ve ever been on, and I’ve been on some great teams. Next week I start a new chapter, I will be joining Anthropic to help them scale out their infrastructure and put my decades of kernel and systems experience to use. I will be stepping back from kernel development as my primary job for the first time in my career. I’m sad to leave my colleagues, but I’m excited to try something new and see where it takes me.

@josefbacik "I will be stepping back from kernel development as my primary job for the first time in my career."

Thanks, I hate it. 😭 😭

But I'm very happy for you otherwise! Go have a lot of fun!

@josefbacik I'm honestly very saddened by this because not just are you one of the most brilliant and technically skilled people I know you are also a fucking great human being and amazing communicator!

@josefbacik Josef Bacik, a prominent Btrfs engineer at Meta, wrote about the magnitude of impact for Meta's Btrfs usage, then proceeded to quit Btrfs, Meta, kernel.

You'll be missed :(

@josefbacik congrats on the new job?

@josefbacik that was meant to be a definitive '!' but it also works that way. Curious to know how much open source there will be at Anthropic. Godspeed.

@josefbacik does this mean the good uncle position in kernel development goes vacant??

@ljs @josefbacik *shakes branches in a threatening manner*

@lkundrak @josefbacik IIRC they used to give talks about Btrfs with Chris Mason where Chris gave the "god cop" part and Josef the "bad cop" part.

@vbabka @josefbacik who did the "look the racoon got a meth pipe... oh he got another one! he's trying to smoke it... no way..." cop part??

@josefbacik Oh wow ... I'm glad for you, but you'll be badly missed in these parts. Do come visit sometimes, OK?

@corbet of course, I'll be at All Systems Go next month to talk about systing. Just shifting my focus a bit.

@josefbacik @corbet CANNOT WAIT!

@josefbacik I'm super-sad to see you go, you've been a treasure and great to work with over the past ten years of Btrfs in @fedora and upstream Linux. 😭

Good luck on your next great adventure at Anthropic and have fun doing it! 🤠
