Lazygit changed how I use git, it is so easy to do all the daily essentials like branching, committing, and merging, but also also does more advanced things like interactive rebasing when needed.
I had searched for a proper git client, that was free and open source plus worked on both Linux and Windows, for a long time and I haven't looked back after finding lazygit.
Currently Endeavour OS, but I mainly daily drive Fedora, because its the right mix between bleeding edge and stable (stableedge?) for me.

MQTT is just a messaging protocol, it's mostly used for iot purposes like you mention, but can in theory be used for any kind of project.
Never used ejabberd, but one of their selling points are multiprotocol support, so it's not so weird to support a multipurpose standardized messaging protocol.
Literally how SnowPiercer started, and I am all for it, train based survival here we go!
