Review: Hands-On Intro to Kubernetes

It’s 2017. Containers are “a thing.” For real. A few years ago, we were kind of wondering if they were, or if they were just a passing fad. Those of us who were busy Getting Things Done(™) don’t have time for all of the fly-by-night technologies that show up on HackerNews for a week, only to fall by the wayside. That’s the cheap excuse I’m using to justify my lack of experience with Docker, Kubernetes, and the whole containerization movement that has crept up in the past few years.

Welcome to LISA17!

I’ve been coming to LISA since 2009, and I’ve always wondered why the official conference opening was on Wednesday, when the party really starts on the Saturday prior. This year’s LISA in San Francisco is no different.

Interview with Chastity Blackwell on Her Upcoming LISA17 Talk on Documentation

I’m a fan of documentation. I have been, ever since I first inherited an infrastructure and had to try to figure out what the previous admin had done. I try to write decent documentation—documentation that I wish had been was there when I first tried to learn about a particular system. I also find myself doing so much that what I can keep in cache in my brain is limited, and stuff I’ve worked on tends to “page out,” so to speak. Writing good docs is an excellent way to do your future self a favor.

Interview with Eben Freeman on His Upcoming LISA17 Talk on Queuing Theory

Working in IT operations these days can be challenging as it seems like there’s an ever-increasing curve in terms of the knowledge you need to have. Fortunately, there are tools that help simplify what we need to do. Rather than constantly observe workloads and manually respond by building the services we think we'll need, pretty much all production-ready cloud providers and services offer autoscaling and demand-driven resources. But what are the implications of handing off this decision-making?

SREcon17 Americas Program Selection Process

The following post has been collaboratively written by the co-chairs for the SREcon17 Americas conference (Liz Fong-Jones and Kurt Andersen) and several of the program committee members (Murali Suriar and Betsy Beyer). It is intended to provide greater insight into the selection process which we used for this conference and may not entirely match the strategies which other conference committees employ.

USENIX Reaction to Presidential Executive Order “Protecting The Nation From Foreign Terrorist Entry To The United States”

USENIX, the Advanced Computing Systems Association, strongly objects to President Trump’s Executive Order “Protecting The Nation From Foreign Terrorist Entry To The United States,” signed on January 27, 2017, which suspends the issuance of visas and other immigration benefits—including entry into the United States—to nationals of “countries of particular concern.”

LISA16—You've Been Hacked! (Entirely in Safety)

“You’ve been hacked!” The cry echoes around the ballroom. A couple of dozen bemused and anxious faces turn to Branson on the podium as he grins and nods. The members of the four teams turn back to each other and their laptops and begin trying to find out what just happened.

LISA16—Geeks Are Social Beasts. Really.

Geeks Are Social Beasts. Really.

OK, perhaps some of the people I went to dinner with last night would object to the label “geek.” I don’t. I embrace it fully. To me, it indicates a person who finds joy in the passion of learning and working and making things, and sharing that passion with others. Labelled or not, all the people in the group I led last night fit that description.

LISA16 Build - Feeling Like a Roadie

I feel like the newbie on a crew for a rock band on tour.

LISA Build is both a service to the LISA conference and a learning experience for the volunteers. I’m an old guy. I remember doing deployments like this (though we only had wired networks). I don’t think I remember the last time I worked on an operations project with this much intensity. It’s FUN, but I know I’m going to sleep well tonight.

LISA16 Build—The Spirit of Sysadmin

LISA16 Build - The Spirit of Sysadmin

It's the way of any power user: the network is never fast enough. Given the chance, I’m sure we could do better. So when we get to a conference with a thousand or so other people, and the wireless network stinks (or so we think), it's not the Way of the Sysadmin to just let it go.
