Read more ...Datacenter RPCs can be general and fast Kalia et al., NSDI’19
We’ve seen a lot of exciting work exploiting combinations of RDMA, FPGAs, and programmable network switches in the quest for high performance distributed systems. I’m as guilty as anyone for getting excited about all of that. The wonderful thing about today’s paper, for which Kalia et al. won a best paper award at NSDI this year, is that it shows in many cases we don’t actually need to take on that extra complexity. Or to put it another way, it seriously raises the bar for when we should.
eRPC (efficient RPC) is a new general-purpose remote procedure call (RPC) library that offers performance comparable to specialized systems, while running on commodity CPUs in traditional datacenter networks based on either lossy Ethernet or lossless fabrics… We port a production grade implementation of Raft state machine replication to eRPC without modifying the core Raft source code. We achieve 5.5 µs of replication latency on lossy Ethernet, which is faster than or comparable to specialized replication systems that use programmable switches, FPGAs, or RDMA.
eRPC just needs good old UDP. Lossy Ethernet is just fine (no need for fancy lossness Continue reading

It should come as no surprise to anyone that I’m a huge supporter of Spousetivities, and not just because it was my wife, Crystal Lowe, who launched this movement. What started as the gathering of a few folks at VMworld 2008 has grown over the last 11 years, and this year marks the appearance of Spousetivities at an entirely new conference: Oktane 2019!
Oktane is the conference for Okta, a well-known provider of identity services, and the event is happening in San Francisco from April 1 through April 4 (at Moscone West). This year, Okta is bringing Spousetivities in to add activities for those traveling to San Francisco with conference attendees.
What sort of activities are planned? The Oktane19 Spousetivities landing page has full details, but here’s a quick peek:
…and more!
If you’re attending Oktane19 and are bringing along a spouse, domestic partner, family member, or even just a friend—I’d definitely recommend signing them up for Spousetivities. Continue reading
It’s been a little while now since I published my 2018 project report card, which assessed my progress against my 2018 project goals. I’ve been giving a fair amount of thought to the areas where I’d like to focus my professional (technical) development this coming year, and I think I’ve come up with some project goals that align both with where I am professionally right now and where I want to be technically as I grow and evolve. This is a really difficult balance to strike, and we’ll see at the end of the year how well I did.
Without further ado, here’s my list of 2019 project goals, along with an optional stretch goal (where it makes sense).
Make at least one code contribution to an open source project. For the last few years, I’ve listed various programming- and development-related project goals. In all such cases, I haven’t done well with those goals because they were too vague, and—as I pointed out in previous project report cards—these less-than-ideal results are probably due to the way programming skills tend to be learned (by solving a problem/challenge instead of just learning language semantics and syntax). So, in an effort to Continue reading

Trying to remove cyber security risks from the growing world of connected things is not an easy task. That said, there’s no time like World Consumer Rights Day to give Canada a shout out for its global leadership to champion a safer digital future for all.
Recognizing the need to secure the Internet of Things (IoT), the Internet Society, in partnership with the Ministry of Innovation Science and Economic Development (ISED), the Canadian Internet Registration Authority (CIRA), Canadian Internet Policy and Public Interest Clinic (CIPPIC), and CANARIE, led a voluntary multistakeholder process to develop a broad-reaching policy to ingrain security at the core of innovation in Canada.
Over the past year, we led a series of meetings with business leaders, technical experts, government representatives, civil society, and academia to discuss challenges and recommend the best ways to address them. We gathered feedback through in-person and online attendance. Collectively, these efforts, combined with well-rounded research and documentation, formed the Canadian Multistakeholder Process for Enhancing IoT Security.
Rather than a top-down, government-imposed regulatory model, our multistakeholder approach helped us balance roles and contributions among the group. By working in a way that includes feedback from all participants, we are developing IoT security Continue reading
Ladies and gentlemen, I would like you to welcome the new shiny RFC8482, which effectively deprecates the DNS ANY query type. DNS ANY was a "meta-query" - think of it as a similar thing to the common A, AAAA, MX or SRV query types, but unlike these it wasn't a real query type - it was special. Unlike the standard query types, ANY didn't age well. It was hard to implement on modern DNS servers, the semantics were poorly understood by the community and it unnecessarily exposed the DNS protocol to abuse. RFC8482 allows us to clean it up - it's a good thing.
But let's rewind a bit.
It all started in 2015, when we were looking at the code of our authoritative DNS server. The code flow was generally fine, but it was all peppered with naughty statements like this:
if qtype == "ANY" {
// special case
}
This special code was ugly and error prone. This got us thinking: do we really need it? "ANY" is not a popular query type - no legitimate software uses it (with the notable exception of qmail).
Wake up! It's HighScalability time:
The web is 30! Some say it's not the web we wanted. But if we got that web, would it have ever grown so big? Worse usually is better.

On today’s sponsored Heavy Networking episode we explore how AppNeta wraps user metadata around Netflow records, deep packet inspection, and discovery of networks to help engineers get a continuous view of end user performance and the telemetry to find and fix problems.

At DockerCon Copenhagen we launched the Docker Pals program in order to connect attendees and help them make the most out of their trip. Attending a conference for the first time or by yourself can be intimidating and we don’t want anyone to feel that way at DockerCon! Pals get matched with a few others who are new (the “Pals”), and someone who knows their way around (the “Guide”) so you will have a familiar group before you arrive at the conference. Guides help Pals figure out which talks and activities to attend, and are available for questions.
This year we are excited to grow the program, matching more groups and adding Meet-and-Greets throughout the week. You won’t want to miss the best version of Docker Pals yet!
Here’s what Pals had to say about DockerCon Barcelona:
“Docker Pals made my DockerCon experience ten times better and I’ve made friends I hope to see again!”
“Our Guide was very helpful and I really enjoyed meeting other Pals at the conference.”
“[I enjoyed] the fact that even though I was there alone I always had a place to turn for help and fellowship.”
“[Our Continue reading
