# Memex Welcome to my [Obsidian](https://obsidian.md)-based [[personal knowledge management|personal knowledge management (PKM)]] [[digital garden]]... thing! Or whatever you want to call this kind of [[Non-linearity|non-linear]], link-based [[wiki]] notes ...thing? Some might call it a [[second brain]], a [[Zettelkasten]], or simply a [[knowledge base]] similar to a personal Wikipedia. But, I have tended to name my various personal note systems "Memex" based on [[Vannevar Bush]]'s ahead-of-its-time [[Memex (concept)|memex concept]]. So, that's what I've been calling my Obsidian-based system too. ![img](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEge_cvWfNKCGvyxM9V09H-yoPPqZ__aQWwI0k45Puf52NecKjtBbqxPLv5V5gZQTA2BHBExDzqQh3MGdML3kaqfNS0sRazcEThs7evQNuy2r6xC7J-kp4YtIlpcibZ3bGvnFvuSCCbOK2U/s1600/memex2.jpg) *[Vannevar Bush's "memex" concept]* ## Non-linear, Linked Notes This kind of note system (PKM/zettelkasten/wiki) relies heavily on links - not only traditional *forward* links like in webpages, but also "*backlinks*," which are links to notes that *themselves* link to that current note. These backlinks are listed at the bottom of each note and are crucial because they provide structure and basic organization with minimal effort. The usefulness of the links grow exponentially as you add notes and links because of the sometimes surprising relationships you discover among your own thoughts that you may not have otherwise recognized. These links are also represented visually in the local graph in the right sidebar. And you can also view all of my published notes together in a graph view by clicking on the Global Graph button in the upper right graph. Here is what my Global Graph looks like in my local Obsidian app on my Mac: ![[graph.jpg]] *[Only some of these notes I make public on this website.]* I use a type system where most notes are given a type and have default fields and colors. E.g, light green = general concepts/terms, turquoise = technology, purple = personal projects/responsibilities, red = sources/books/bookmarks, beige = people/organizations, dark green = places, blue = my notes/writing/thoughts, yellow = folders/organizational/MOCs/mind maps. ## Thoughts on PKMs, Thinking with Notes, and Non-linear Writing - [[On why and how I use Obsidian as my PKM]] - [[On PKMs and the extended mind thesis]] - [[On notes as thinking]] ## My Notes I am still experimenting with the idea of publishing any of my notes. I don't really have a specific goal in mind other than I like the potential of non-linear and in-progress sharing of notes and thoughts as in the idea of [[digital garden]]s. I am gradually sharing notes in two main areas: 1. General concepts and topics of interest I learn about, which include [[Codex/Academia/Humanities, Arts, & Social Sciences/Philosophy/Philosophy|philosophy]], [[ethics]], and [[critical thinking]] 2. My notes on [[Codex/Tech/Tech|technology]] which include [[Codex/Tech/Programming|programming]], [[DevOps]], and [[Making|maker culture]] ([[Raspberry Pi]]s and [[electronics]]) ### Some General Jumping Off Points - [[Philosophy]] - [[Ethics]] - [[Philosophy of technology]] - [[Critical thinking]] - [[Logic]] - [[Fallacy|Fallacies]] - [[Bias]] - [[Ludwig Wittgenstein]] - [[Friedrich Nietzsche]] - [[Immanuel Kant]] - [[Hannah Arendt]] - [[Tech|Technology]] - [[Programming]] - [[DevOps]] - [[Operations, IT, & Infrastructure|Infrastructure]] - [[Politics]] - [[Good to Know™]]
