A great question came up on the mechanical-sympathy list that many others probably have as well:
I keep hearing about [Docker] as if it is the greatest thing since sliced bread, but I've heard anecdotal evidence that low latency apps take a hit.
Who better to answer than Gil Tene, Vice President of Technology and CTO, Co-Founder, of Azul Systems? Like Stephen Curry draining a deep transition three, Gil can always be counted on for his insight:
And here's Gil's answer:
Putting aside questions of taste and style, and focusing on the effects on latency (the original question), the analysis from a pure mechanical point of view is pretty simple: Docker uses Linux containers as a means of execution, with no OS virtualization layer for CPU and memory, and with optional (even if default is on) virtualization layers for i/o.
From a latency point of view, Docker's (and any other Linux container's) CPU and memory latency characteristics are pretty much indistinguishable from Linux itself. But the same things Continue reading
The Datanauts talk about their home lab setups, including issues with location, noise, and power consumption. They also examine cloud and online options, and discuss the surprising amount of lab work you can do with just a laptop.

Every once in a while, I like to see who is clicking through to my blog. It helps me figure out what’s important to write about and who reads things. I found a recent comment that made me think about what I’m doing from a different perspective.
I get occasional inbound traffic from Reddit. The comments on Reddit are a huge reason to follow threads on the site. In one particular thread on /r/networking linked back to my blog as a source of networking news and discussion. But a comment gave me pause:

And I quote:
Cons : they almost all know each other and tend to promote each other content.
This was a bit fascinating to me. Of the people in that particular comment, I’ve only ever met one in person. I do know quite a few people in the networking space as part of my career, both related to Tech Field Day and just through writing.
It is true that I share quite a bit of content from other writers. My day job notwithstanding, I feel it is my duty to identify great pieces of writing or thought-provoking ideas and share it Continue reading
As a side benefit, Ciena won’t need a third-party controller anymore.
Juniper recently launched their Tomahawk-based switch (QFX5200) and included a lot of information on the switching hardware in one of their public presentations (similar to what Cisco did with Nexus 9300), so I got a non-NDA glimpse into the latest Broadcom chipset.
You’ll get more information on QFX5200 as well as other Tomahawk-based switches in the Data Center Fabrics Update webinar in spring 2016.
Here’s what I understood the presentation said:
Read more ...Being English and being constantly exposed to bad language practice (not the curse word type), during a recent trip to Switzerland, I totally failed in keeping my English plain and vanilla. Their English was better than my own and in this sense I totally failed. Here is my top five of innocently said statements that just do not translate. If nothing else, it might help you to not make the same mistake when presenting to others not of your own tongue.
1) Shooting fish in a barrel
2) Stuck under a rock
3) Lots of ways to skin a cat, including with a machine gun
4) Everything including the kitchen sink
5) More features than you can shake a stick at
Speaking English is really hard to do when you’re English!!!
