This should have happened to me someday, and it finally did. I got Kernel panic on my Fedora 43 workstation. Apparently, a software update went south, and the PC was turned off before it properly finished. The general advice would be to boot from a previous kernel and regenerate everything. Unfortunately, this wasn’t an option for me, because I couldn’t boot into older kernels as well. Luckily, it’s easy to overcome this whole situation with a LiveUSB stick and a couple of terminal commands....

Initially, I wrote this article in Ukrainian, but I decided to translate it to English and share it with a broader audience. I also added some suggestions from the comments and removed some regional-specific references, but overall the text is mostly unchanged compared to the original. Why am I even writing this? I participate in the hiring process for my company. Also, I’ve gone through quite a few interviews in my life....

I’m writing a post on NeoVim and NeoVim GUI configuration mostly for myself. Even though I have all my dotfiles on the Github, some configuration requires gluing. Also, some things have to be executed in a particular order and some configs must exist in particular places. I spent some time looking for fixes for occasional issues and polishing some rough edges. So, here I just want to put it all together, so I won’t need to go down the googling spiral if I need to set up a new development environment for myself....

Pulumi is just another Infrastructure as Code tool, yet it’s different from what I’ve seen before. It offers some interesting concepts like usage of the generic purpose programming languages, state tracking, etc. I had some time recently so I decided to play around with it. Here I want to share some thoughts about this tool. In my opinion this is the first IaC tool, which was created for the “Dev” side of “DevOps”....

Image source I’ve been using Kubernetes for almost a year and want to share some takeaways and things I’ve learned about it so far. Some context. We had a team of two engineers working not only on Kubernetes but on all infrastructure-related topics. Our main application was a Python monolith, plus a few satellite-services. Our infrastructure was dynamic due to autoscaling, and a lot of things were optimized for costs (check out my article about running Kubernetes on AWS Spot instances)....
