Open Mainframe Summit 2022

On September 21st I headed to Philadelphia for my first in-person event since March 2020, the Open Mainframe Summit! The Linux Foundation kicked off this event in 2020, and it swiftly went virtual for two years. This means it was the first time this event had been in person too. Masks and either vaccination or […]

Colds, parks, and holidays

We’ve all been sick a lot. It seems we’re in the midst of what all families go through when their kids first go to (pre)school, a non-stop parade of colds that are annoying, but not severe enough to require anything beyond rest and cold medicine. We have the added fun of regular COVID-19 tests, both […]

A jellyfish and a mainframe

Happy Ubuntu 22.04 LTS (Jammy Jellyfish) release day! April has been an exciting month. On April 5th, the IBM z16 was released. For those of you who aren’t aware, this is the IBM zSystems class of mainframes that I’ve been working on at IBM for the past three years. As a Developer Advocate, I’ve been […]

I 3D-printed an IBM LinuxONE!

Several months ago I 3D printed an IBM z15 pencil holder. I used a design that had been floating around, so it wasn’t perfect, but it was a nice little model. I ended up following up with a design team inside of IBM and got a more perfect version that they were OK with me […]

I 3D-printed an IBM z15 model!

Back in April as I was catching up with work following my maternity leave, I discovered the existence of some internal IBM 3D printer files for IBM z15 pencil holders. I was immediately intrigued, and quickly found a 3D printer company that would print one for me. As a quick aside, I learned about 3D […]

Ubuntu 20.04 LTS… on Big Iron!

Today we saw the release of Ubuntu 20.04 LTS! Alongside the fanfare of a new server and desktop release for AMD64, and my own beloved Xubuntu, this new version walks in the path of 16.04 and 18.04 to be the third LTS to support the s390x mainframe architecture for IBM Z. If you have been […]

Ubuntu and the new IBM LinuxONE III LT2

Back in September I wrote about Ubuntu on the new LinuxONE III. For the release of this new mainframe, there were balloons, and cake, and we had a great time celebrating. With Shelter in Place orders spreading throughout the US, we don’t have cake this time, but we do have a new hardware release! The […]

SCALE 18x

On March 4th the world looked a lot different than it does today. I had a work trip to Singapore canceled due to COVID-19 concerns about travel to Asia, and the first US domestic cases had started popping up. A few conferences were starting to cancel, go virtual, or postpone, but it wasn’t the landslide […]

Highlights of LCA 2020 in Gold Coast

I already wrote about the tourist stuff I did while in Brisbane and Gold Coast, but the actual reason for my trip to Australia was to present at Linux.conf.au (LCA). One of the things that is particularly remarkable about LCA is the length of the conference. Most conferences I go to top out at three […]

Our upcoming Webinar on Security with Ubuntu and IBM Z

My first interaction with the Ubuntu community was in March of 2005 when I put Ubuntu on an old Dell laptop and signed up for the Ubuntu Forums. This was just a few years into my tech career and I was mostly a Linux hobbyist, with a handful of junior systems administrator jobs on the […]
