September 15, 2016Turtles on the wire: understanding how the OS uses the modern NIC by Robert Mustacchi
For this entry, we're going to be focusing on how the Operating System sees NICs, what abstractions they provide together, how things have changed to deal with the increased tenancy and performance demands, and then finally where we're going next with all this. We're going to focus on where scalability problems have come about and talk about how they've been solved.

August 18, 2016TCP Puzzlers by Dave Pacheco
It's been said that we don't really understand a system until we understand how it fails. Despite having written a (toy) TCP implementation in college and then working for several years in industry, I'm continuing to learn more deeply how TCP works — and how it fails. What's been most surprising is how basic some of these failures are. They're not at all obscure. I'm presenting them here as puzzlers, in the fashion of Car Talk and the old Java puzzlers. Like the best of those puzzlers, these are questions that are very simple to articulate, but the solutions are often surprising. And rather than focusing on arcane details, they hopefully elucidate some deep principles about how TCP works.

July 29, 2016dtrace.conf(16) wrap-up by Bryan Cantrill
Something that got a little lost in the excitement of Samsung’s recent acquisition of Joyent was dtrace.conf(16), our quadrennial (!) unconference on DTrace. The videos are up, and in the spirit of Adam Leventhal‘s excellent wrap-ups from dtrace.conf(08) and dtrace.conf(12), I wanted to provide a survey of the one-day conference and its content.
