What OSS tools do you use for personal knowledge & task management?
I've been looking into all sorts of them recently: logseq, appflowy, vikunja, etc. What tools do you use? Why? What problems did you run into with the previous set of tools you used for this job?
Right now I'm primarily interested in finding a "zero-knowledge" (cloud provider doesn't have access to my data) system for task management. Needs to be able to have recurring tasks and tasks organized in some interesting/useful ways (by projects/labels/something, maybe a kanban and table view). Deadlines and time tracking/planning interesting but not required.
For me one of the most flexible and mature way to knowledge base, tasks and notes is an org-mode.
I have two main workflows.
The first one is task management. I have a lot of recurring tasks with tags, deadlines, schedules, etc. All of them are living in org-files in my Nextcloud. On Android I'm using orgzly-reviwed for sync via WebDAV, on my work I'm using organice (via WebDAV) as a "web-version" and also I'm editing my notes in emacs on my laptop (but actually any text editor could be used).
The second one is a knowledge base. I'm using org-roam locally (and with a localhost web server, built in into emacs) and orgnote for Android/Web + synchronization. My knowledge base is Zettelkasten-based.
Yes... org-mode is more than 20 years old... It is a price of flexibility: I have a strong feeling that one can adjust org-mode to any workflow. But I do not use even a third of the org specification. There are a lot of cool blog posts like "org mode quick start" or "org mode basics", I would recommend to start from such posts, not from a documentation.
I keep failing to make Zettelkasten and org-roam work for me. Do you use a single knowledge base for your whole life, with millions of tags and pages? Or should I be making separate directories for each project? Is the "daily journal" the best place to put everything, with well tagged entries?
My preferred system is two big directories, one for your daily notes (dailies, journal, etc), and another for literally everything else.
This is how logseq is implemented, and can easily setup emacs org-roam to do it too. It's very nice because you don't need to worry about where to put something, throw it in your daily journals and get all the info down there, and link densely. If it's about a specific topic, link to it and when you go to that topic you'll see the info in the back links below (logseq does it automatically, emacs take a bit of config). You can then transcribe the important/summary/etc info from all of your aggregated back links into a single well thought out and planned document, or at least a single trimmed down one. Or, just leave all the info in the back links, whatever works best for you
Biggest piece of advice, you don't need to document everything you do in your life. If it's info you might use in the future, a significant interaction or event, fun tidbit etc, add it in. If it's just a casual conversation with someone that you don't learn anything significant or it's something that you'll never link to or use again, just keep it as a memory.
I did a lot of over-capturing early on and got a lot of fatigue from it. Now my note making is as I run across things I'll want to reference in the future (plans that were made, ideas to learn more about later, important phone calls/interactions, notes on articles, updates on projects, etc), with refinement to those ideas coming when I access them again later (or if I'm bored and have time). It's no longer a drain to grow my PKM, it's slower but much more meaningful info
This makes a lot of sense! I'm going to give it another shot with these insights in mind. I think if I frame it as a future-facing tool like you describe I'll avoid a lot of my previous mistakes.
It has org mode, but the links in logseq aren't compatible with org-roam links, so either you use custom elisp to make logseq links into emacs compatible links and can't follow links in logseq, or make emacs notes logseq compatible and can't follow links in emacs.
Also, iirc logseq is planning to drop org mode support when they launch their database update, either that or have it available but not updated anymore.
