Welcome to sysop.ninja

Sysop.ninja is my humble attempt, to document what I do and some times, what I think.

I work as a Linux System Administrator; playing around with different technologies, and some of them ends up being documented here.

Systemd reference

I saw a talk from RHEL summit 2018 about systemd, and decided to make my own resumé / TLDR / refrence-sheet. Feel free to use it, if it’s any good to you.

Debug Linux in 60 seconds

So, I found this video from Brendan Gregg (https://www.youtube.com/watch?v=ZdVpKx6Wmc8), and decided to add some small notes and other examples. It’s not heavily modified; just more novice-friendly, I would say

Writing documentation based on rfc2119.md

I’m trying to write better documentation; and I stumbled upon RFC2119, which I would like to use a lot more. Hence the reason, why I’ve put it at my site.

Upgrading Ubuntu from LTS to non-LTS

Just a small note to me, from me, by me (i forget these things, because i rarely use them)

Compile .rpm with added/new compiler flag

An article from my first blog, back in 2013.

This is just for my own nostalgia, feel free to use it if it makes any sense.
