Micro Services, Macro Problems

I've been thinking and talking about issues of centralized vs. decentralized systems for a long time. Some of my earliest writings on the subject are still around, as archived Usenet posts from 1989 and 1990.

Two Years at Facebook

Yesterday was my second "Faceversary" (i.e. the anniversary of when I started). That's the tenure that I initially thought I had a 50:50 chance of reaching, so it seems like a good time to look back at how I got this far.

Beyond Gluster

I've been thinking a lot lately about what to do after Gluster. Don't worry (or celebrate), Gluster folks; my departure is not imminent. It's just a confluence of several factors.

Don't Dump On Your Users

Over the years, I've worked on many systems that rely on either verbose logging or all-inclusive "state dumps" as primary debugging tools. Gluster is such a system. If you look on the mailing list, "please send logs" is practically always the first response to bug reports, and "please perform this incantation and send us the magical statedump . . .
