Monitoring a mixed fleet of flash, HDD, and NVMe devices with node_exporter and Prometheus in 2 hours
For many years, I've had a Linux box off in the corner that fills a number of useful roles. I used to have something beefier and bigger but it turns out that most of what I really want, I can just do with an Intel NUC. The most recent re-build of my Linux box had me looking around for what sorts of…

10G Ethernet is a Small Form-Factor Pain in the butt 5 years ago
I found out last week that my coworkers were all unaware of what’s been happening to Ethernet while they weren’t looking. See, Ethernet, all of the way up through Gigabit was mostly reasonable. First, they’d make some bad standards, like 10BASE5 or all of the weird not-quite-100BASE-TX standards…

Savvy copyright messaging with responsive images 5 years ago
A long long time ago, I followed Derek Powazek's " Savvy Approach to Copyright Messaging " because, of all of the possible ways to reduce the chances of my images getting borrowed by other folks on the Internet, it seemed to be the best. I see DRM as a fairly dangerous technical equivalent of…

What the link section in a hypermedia API showed me about specifying hypermedia... 5 years ago
What if we stopped trying to write specs for new general-purpose hypermedia formats and redirected our efforts in a different direction? Let me back up a bit, so I can explain myself. I'm the person in a group of randomly selected programmers who talks about APIs. Therefore, when it comes time to…

Moving to a leadership role doesn't mean you won 7 years ago
While I was in the midst of transitioning from a software developer to a manager of software development, I was sitting in a Belgian bar drinking beer with a British gentleman on vacation who managed hotels. And so we got to talking about what it meant to be the boss outside of considerations of…

Littlechef and the great refactoring of the personal infrastructure 7 years ago
One of my favorite DevOps thought leaders thinks I'm nuts. He's right. People should not run their own mail infrastructure, monitoring infrastructure, or DNS infrastructure. On the other hand I kinda started doing it a long time ago and it's worked out pretty well for me, so why should I change?

Monomaniacal littlechef: launching cloud servers, user cookbook, nagios cookbook, and DNS 9 years ago
I'm on a monomaniacal littlechef quest at home. See, I burned a weekend helping a friend set up her chef and vagrant infrastructure some months ago. And I wrote about it. And I figured that it would eventually get back to it and re-do all of my servers. Then I spent some time in sysadmin hell and…

API design: Presets, pre-patched, normalized, or modular 9 years ago
Making APIs is both easy and hard. See, it’s one thing for a software engineer to make a piece of software aimed at a musician or artist who is deeply scared of what horrors lurk inside the chassis, because it’s often times coming from a fear that you may have never understood. Writing APIs is…

DevOps Automation, even for something that may stay small 9 years ago
So one of my friends has a really great idea. I'm not sure if it's a profitable idea, but it's something that needs to be made. And so I made them dinner and gave them an overview of potential technological issues, given that it's something I know pretty well. And I thought I'd recount the refrain I…

Would you rather be a lucky hacker or a smart hacker? 11 years ago
We've got this silly tendency to glamorize the concept of being irreplaceable. "Yay!" you say, "I can be so cool that, even if I have a bad day, the company will lay every other engineer off before they get rid of me! I'm irreplaceable!" This is often about luck. Being the last guy to actually…
