The end of my journey at Canonical, and new adventures ahead

I am a staff engineer at Canonical, where I have worked for six years. My time here has been filled with brilliant people and amazing technology, and I’ve had the pleasure and privilege of playing pivotal roles getting a number of new projects off the ground. As I’ve said in the past, I joined Canonical to help my technical growth, and they delivered in spades. I have really loved my time here, which made the decision to leave all the more difficult....

How to build a snap using ROS 2 Foxy

The snapcraft CLI (the tool used to create snaps) has long had support for building snaps that use both ROS 1 and ROS 2.

Robotics security: What is SROS 2?

We at Canonical have been hard at work on the security features of version 2 of the Robot Operating System (ROS 2). However, if we lift our collective heads up out of the weeds it’s easy to see folks completely misunderstanding how security works today in ROS 2. We’ve written some design articles to help distill all the moving pieces into something comprehensible, but I wanted to do the same here in a slightly less formal way....

Cipher update for the Nextcloud snap

Security is a always a balancing act between safety and practicality. If we’re talking about the internet, you can go all the way from something impenetrable and completely useless to something easy to use and also part of a botnet. In the case of the Nextcloud snap’s SSL cipher suite, as with any website, it’s a balance of supporting only the best ciphers while also ensuring that older clients aren’t left out in the cold....
