Haha nothing that exciting, and maybe even a stretch to call it "software"
Mostly just some python and jinja for klipper 3d printers and some guides and stuff for the same.
I've been working on a big project to add a lot of functionality through a python extension that is traditionally done somewhat manually with macros and jinja. The idea is to make it easier for new/inexperienced users to handle functions like filament runout/changes and preprint steps like heat soaking and generating a bed mesh on any printer without needing to understand jinja or gcode.
Actually imo for most people it's not gonna be better than WiFi.
There's a fairly high chance of having issues depending on your electrical wiring and choice of outlets.
Additionally the latency is not amazing and while you may get higher raw bandwidth (if your WiFi is old and you signal is garbage) for a lot of users latency has more of an effect on the quality of their experience and if it's not any better than their WiFi was they aren't likely to be all that impressed.
I would either upgrade the WiFi instead or suck it up and run some Ethernet.
The cables can often be easily tucked under the moulding between the wall and floor, especially if you have carpet. Ethernet is low voltage so you do not really need an electrician to wire it for you.
Worst case find a way to shove it through the walls or behind some moulding, it's not a fire risk at that wattage so go nuts. No matter how annoying the effort, in the end you will be much happier for much longer than any other solution.
It depends what I'm backing up and where it's backing up to.
I do local/lan backups at a much higher rate because there's more bandwidth to spare and effectively free storage. So for those as often as every 10 mins if there are changes to back up.
For less critical things and/or cloud backups I have a less frequent schedule as losing more time on those is less critical and it costs more to store on the cloud.
I use Kopia for backups on all my servers and desktop/laptop.
I've been very happy with it, it's FOSS and it saved my ass when Windows Update corrupted my bitlocker disk and I lost everything. That was also the last straw that put me on Linux full-time.
Oh that's just your language processing module.
If it was the listening module you would hear nothing at all or just static
