LinuxFest Northwest (LFNW) is a local community conference about Linux put on every year by the Bellingham Linux Users Group and Bellingham Technical College. I spoke at LFNW last year, and had a proposal accepted again to speak this year. Unfortunately, COVID-19 threw a wrench in it, and the conference had to be canceled due to health concerns. The conference moved to an online conference made up of pre-recorded sessions (webinar-style), with an online discussion board. I recorded one of my sessions. This post is here to document what I did, as a first-time online presenter who primarily uses Linux.
Note: This post was originally published on the AWS Containers Blog. On March 10, 2020, we introduced Bottlerocket, a new special-purpose operating system designed for hosting Linux containers. In this post, I want to take you through some of the goals we started with, engineering choices we made along the way, and our vision for how the OS will continue to evolve in the future.
With the outbreak of COVID-19, many large events like conferences are being canceled or rescheduled. SCALE is still on, and I’ve still traveled down to Pasadena for it since I don’t get to visit my family in LA frequently enough. However, different people have different risk assessments and/or tolerance, so the schedule has changed a fair bit. As I published previously, I’m sharing my intended schedule. Here’s the revised version. If you feel like you want to join me, let me know!
Note: A revised schedule is available. I’ll be speaking at the Southern California Linux Expo, otherwise known as SCALE (or SCaLE). I’d love if you came to see me! This is my first time attending the conference, but I grew up in Los Angeles and it’ll be nice to go to a conference there. SCALE is a community-oriented conference about Linux and other free and open source software. It’s similar to LinuxFest Northwest up in Bellingham, WA, but I think SCALE is larger. For me, the subjects I tend to be most interested in are containers, security, Linux, and other operating systems. My schedule is going to be focused around those topics, but the nice thing about a community conference like this is the variety of talks. I want to try something new for this conference: publishing my intended schedule. If you feel like you want to join me, let me know!
One of my colleagues recently asked me if there were any best practice guides for designing and testing software daemons (background processes). I hadn’t known of any before writing this blog post (and most of what I’ve found while researching were related to the mechanics of writing daemons), but we came up with a few ideas together and maybe this can serve as a starting point for others.
Note: This post was originally published on the AWS Compute Blog. On Monday, February 11, CVE-2019-5736 was disclosed. This vulnerability is a flaw in runc, which can be exploited to escape Linux containers launched with Docker, containerd, CRI-O, or any other user of runc. But how does it work? Dive in!
