Most of the screen shots and references relate to LogSeq, but you can adjust them to your needs. The solution described here is one in which the synchonization with the repository will be manual. In this scenario, one would synchronise with the repo before opening the tool (LogSeq in my case) and update the repo again when you're done.

GitHub is installed, and the repo is cloned to this folder. The Termux folder used for the repo has to be refle...

This “default deny” posture ensures that no internal services are accidentally exposed, creating a controlled environment where all communication is initiated from within your trusted network. A common and potentially dangerous misconception is that Network Address Translation (NAT) alone provides sufficient security. While NAT obscures internal devices, it is a routing mechanism rather...
