My Digital Zettelkasten That Connects Data Engineering and Much More
I'm sharing my public Second Brain - a digital Zettelkasten that connects my knowledge across Data Engineering, Personal Knowledge Management, Programming, Productivity, and philosophical topics like Digital Minimalism. Built with Obsidian and published using Quartz/GoHugo, this knowledge vault contains interconnected notes that I've crafted, curated, and connected over years. I've developed a streamlined publishing workflow where I simply add #publish to any note I want to make public, then run make deploy through a custom Rust script that's 30x faster than my original Python…

What it does
A crafted digital vault of curated knowledge where insights and ideas connect and compound, modeled after a Zettelkasten to inspire learning and discovery.
Welcome to my public Second Brain, a crafted knowledge vault where my notes, ideas, and insights are carefully curated , connected , and compounded over time. This vault is modeled as a digital Zettelkasten and Garden . Use the search bar on the top right or press cmd+k ( ctrl+k on Windows) to find any term, or open the full search page . Click on a note and follow the links and backlinks to dive deeper, or use Graph Explorer for semantic search and hidden connections. Interact with the graph at the bottom of the page to visualize connections between notes and navigate directly.

My Public Second Brain (https://brain.sspaeti.com) is built with the help of a wonderful tool called Quartz (https://brain.sspaeti.com/quartz-publish-obsidian-vault/). Obsidian (https://brain.sspaeti.com/obsidian/) has become my favorite for note-takers, given its flexible and linked structure that closely mirrors our natural way of thinking. With Quartz, I was able to seamlessly publish my Obsidian notes to a public vault, providing the groundwork for my Public Second Brain. The journey of making this possible involved some scripting as…
Second Brain2025 · second-brain-lac-ten.vercel.app · ▲281Hi HN, I'm Dom, a solo founder. I built Second Brain to solve a common issue I had with AI chats: the knowledge disappears. There’s no structure, no memory, and no way to reuse or build on them. So I built a tool that combines AI chat with a visual, interconnected knowledge system. Key features: - Save AI responses into editable docs (Notion-style Pages). - AI Visual board with multiple content & chat nodes (like Miro meets ChatGPT). - Add and chat with YouTubes, TikToks, Audio, PDFs, GitHub repos, Looms, websites, etc. - Organize using Projects and Smart Tags — then chat with full contexts.…

An AI zettelkasten that extracts ideas from articles, videos, and PDFsDec 2025 · github.com · ▲38Hey HN! Over the weekend (leaning heavily on Opus 4.5) I wrote Jargon - an AI-managed zettelkasten that reads articles, papers, and YouTube videos, extracts the key ideas, and automatically links related concepts together. Demo video: https://youtu.be/W7ejMqZ6EUQ Repo: https://github.com/schoblaska/jargon You can paste an article, PDF link, or YouTube video to parse, or ask questions directly and it'll find its own content. Sources get summarized, broken into insight cards, and embedded for semantic search. Similar ideas automatically cluster together. Each…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
