I'd rather not share the actual repo, it's a mess and also has some semi-private stuff in it. At some point, I may go through and clean some of this up and publish it, but for the moment it really is an extension of my brain--imagine publishing a feed of your thoughts directly to the world (Twitter notwithstanding).
I can, however, give you an idea of how it works. There are many personal wiki programs out there; I settled on Zim[1] as it stores everything in plain-text files and supports a basic markup. On my phone I have the repo set up with Pocket Git[2], and I view it with Coastline[3] (which is just an arbitrary text editor; I don't mind reading the Zim syntax). The Git repository is stored on BitBucket[4] since they offer free private Git hosting, though I now have my own VPN and am considering moving the repo there. Syncing is done periodically (roughly once a month) by committing, merging, and pushing, usually with a few minor edit conflicts to the more popular pages.
Pages are organized into a very loose and fluid hierarchy; for the most part I put things someplace that seems reasonable and then periodically merge, split, and move pages when they grow too unwieldy. The major parts of the hierarchy are:
- Project:(Active/Complete/OnHold): major projects (anything from Barcamp2015Presentation[5] to NewCellphone to BetterWorld[6]) get a page, which collects a narrative about the progress of the project, a summary of the current state, and any relevant links or quotes; this page may have subpages as well.
- Entity:* collects links for anything related to someone or some company I've been involved with; mostly this is backreferences to projects I've worked on for them etc. For example, Entity:Person:JohnSmith could link to Project:Complete:JohnMidiController for a side project I did for a friend.
- Hardware:* collects everything hardware-related, for example Hardware:Computers:RaspberryPi has links to pinout diagrams and the like.
- Software:* collects software-related pages, with subsections for Software:Protocols, Software:Programs, and a smattering of loose pages.
- Snippets:* covers code snippets, such as Snippets:Bash, Snippets:Python, and so on.
This covers about 75%; the other 25% is somewhat less organized and consists of things like fiction ideas, links that don't fit anywhere else, the aforementioned LifeSkills namespace, and Miscellaneous:Quotes:FunnyPhrases ("you there, wear these groceries"[7], "Turns out I'd just existed inconveniently at you"[8]).
Hopefully this rather long post answers your questions, but let me know if there's anything more you'd like to know.
