notes.24w.in — Second Brain, Public Layer

WHERE I
THINK
OUT LOUD.

Not a blog. Not a portfolio. A working second brain — the ideas, frameworks, and connections that are too formed for a draft but too unfinished to call done.

01 — What lives here

THE KNOWLEDGE LAYER

The public slice of a 5,000-note Obsidian vault. Five categories. One rule: if it's worth keeping, it's worth publishing.

01

Frameworks

Mental models, decision tools, and repeatable thinking patterns. The structures I reach for before I know what I'm doing.

  • Johnny Decimal system notes
  • PARA-adjacent workflows
  • Knowledge debt patterns
02

Projects

Active and archived project logs from the TAC2026.2 vault — the thinking behind the building, not just what shipped.

  • 24w.in ecosystem notes
  • Nonprofit ops & fundraising
  • PKM system architecture
03

Ideas

Concepts in transit — too developed for an inbox item, not yet ready to be a project. The stuff that keeps coming back.

  • Technology observations
  • Design language thinking
  • Nonprofit + tech intersection
04

References

Annotated resources, saved thinking from others, and the things I keep linking to because they changed how I see something.

  • Tools I actually use
  • Books / talks / threads
  • System documentation
05

Reflections

The slower writing. Not daily notes — the ones worth rereading. Personal without being private. Honest without being confessional.

  • Year and season reviews
  • Career + purpose notes
  • Letters to future me

03 — Under the hood

THE SYSTEM BEHIND THE NOTES

This is the public surface of a private knowledge system built over years. Here's what it runs on.

5,000+
Notes in vault
3
Active vaults
JD
Johnny Decimal
NAS
Self-hosted sync
Primary Vault
TAC2026.2
The knowledge vault. Thinking, connections, reference. Lives at /container/TAC2026.2.
Action Vault
Second Brain
The execution layer. Tasks, active projects, operational memory. Separate by design.
AI Layer
AI-Assisted, Human-Governed
Claude, Perplexity, and Ollama assist — but the vault charter ensures I never yield authority to the model.
Tool
Obsidian + Bases + Dataview
Plain markdown. No lock-in. Dataview queries, Bases dashboards, and Templater for project scaffolding.
