I believe it’s tied to the ides of the restless dead.

The spirit should move on after death, but some spirits get stuck between worlds. Often it’s related to the circumstances of their death. Maybe they had unfinished business, they died a particularly grousom death, or they were denied a proper burrial.

I think that the answer to this depends on the audience and the topic or nature of the discussion.

I prefer precise, technical language if the audience has experience in the topic. You can save a lot of time by not explaining things that the readers should, reasonably know.

I think simpler language is appropriate for a more general audience or higher level discussion.

It can be challenging to find the right balance on a forum, like this, where you don’t necessarily know who the audience is.

Dbus attempts to provide a standardized system for inter process communication (IPC) without the complexity of managing individual connections between each and every process that needs to share certain types of data.

Not sure exactly what you want, but like this may be what you want. https://github.com/PeterDaveHello/ipinfo.tw

There are simpler solutions that are just a php script on your web server if you’re only interested in IP address (I couldn’t find a good example quickly on mobile)
