iximiuz Labs update: First Content is in, Invites are out ๐
Hello friends!
I've got some news!
First off, I just released the first piece of real content via iximiuz Labs - it's a tutorial Why and How to Use containerd From Command Line. The key "feature" of it is that it's backed by an automated solution checker.
The new tutorial format resembles my "classic" blog posts, but the materials are sprinkled with assignments, and students are expected to interact with the tutorial using the terminal on the right, while the background solution checker keeps a close eye on the state of the microVM. Any combination of the user's actions that brings the system to the "correct" state will make the text on the left send the student a positive reinforcement signal.
There were a lot of fun technical challenges behind this work, and I'll be happy to share them in greater detail in the nearest future, but for now, let me jump straight to the second portion of the news...
"Invite-wall" is going away!
Now anyone with a GitHub account can use the labs. It's still (very) early beta, so all sorts of bugs are expected, and servers can also run out of capacity at some point, but I really want to let as many folks as possible try out the platform.
What's next? I put a lot of effort into iximiuz Labs over the past half a year - all development still happens only in my free time (read - weekends, holidays, and vacations) - but with the last release, I may very well be done with the first version of the engine! So, I'm really looking forward to finally switching back from writing mostly code to doing more balanced work and reviving this newsletter and my other educational activities.
Have fun, do labs, and stay tuned!
Best
Ivan
P.S. Invite-wall is gone, but your support is still much needed!

Hello ๐ It's this time of the month again! My traditional roundup of all things Linux, Containers, Kubernetes, and Server Side, delivered straight into your inbox ๐ฌ What I was working on October was very productive for me - I shipped no major iximiuz Labs features (it's always hard to resist the temptation!) and instead dedicated all my available time to content work. The main focus was on Container Images. It's the subject of the first module of my "panoramic" Docker course, and it is almost...
Hey there, Iโve just finished putting together everything I know about Node.js container images and figured you might find the write-up useful. If youโre working with Node.js in Docker, chances are youโve been hit by the dilemma of which base image to use. Do you go for the default node:latest, the slimmer node:22-slim, or something super minimal like a distroless image? What about Bitnamiโs alternative โ how does it stack up? Before you jump headfirst into your next build, you might want to...
Hello ๐ Ivan's here with a slightly delayed September roundup of all things Linux, Containers, Kubernetes, and Server Side ๐ง What I was working on This month, I worked on an assorted set of topics. Skill Paths First off, the skill paths! I finally finished the underlying machinery, and now iximiuz Labs supports a new type of content - short roadmaps that you can use to develop or improve a specific skill: how to debug distroless containers, how to copy images from one repository to another,...
