To all the people who are waking up to the value of Markdown, @obsdmd, and file-over-app combined with AI, give me a follow. I've been doing all this for years now. Got a lot of cool ideas to share 😜

I'm building more and more AI skills into my @obsdmd vault. Knowledge Management is more and more useful in my life and these help a ton on all fronts: personal organization, clarity, thinking, research, exploration, productivity, health, habits, and more

@kentcdodds Timeless ideas rule

100% This is why I think it would be futile for me to teach you coding workflows. By the time I've put together good material, everything's already changed. Durable skills (product sense) are what you should be working on and that's what I'm teaching next.

@ednico_ @tana_inc Their main target will clearly be organizations

Finished watching the @tana_inc AMA - interesting, but seems to be a bit of a knee-jerk reaction to try and capture the masses/corporates. Will be interesting to see where it goes, but maintaining 2 products, tricky.

I create many more AI skills than I write code nowadays. Fun times :) New job title: Skills Master

@kentcdodds @__mharrison__ Most of it is getting backed into the models. But the most valuable part remains; knowledge about you, your projects, your preferences, goals, ...

@__mharrison__ We spent all that time context engineering only to find out that the tools made those skills unnecessary. Makes you wonder what other workflow maxing we're wasting our time on.

Everyone knows that the last 40% of the context window of AI models start to get pretty unreliable... Except I don't experience this at all 🤔 My two primary AI tools are Cursor (mostly GPT 5.4) and ChatGPT with very long conversations. Cursor compacts and it's still does fine.

@TfTHacker I have multiple such properties on my notes, so I need to be able to point at the right ones

@dSebastien The properties you defined, they just need to be a date that represents a start in another one that represents an end date.

Timeline for Bases A Gantt-style timeline view for Obsidian Bases. Point any Base at a folder of notes with date frontmatter and get a visual horizontal timeline. Features - Time scales — view by day, week, month, quarter, or year - Drag to reschedule — move or resize bars; frontmatter dates update automatically - Multi-select — Shift+click multiple bars and drag them together - Grouping — group by any frontmatter property; drag rows between groups to reassign - Point tasks — notes with only a start date render as a single-day marker - Right-click menu — Open, Edit dates, Duplicate, or Delete from the bar - Hover preview — shows Obsidian's native page preview on hover - Sample Base generator — creates a ready-to-use Base with 10 sample tasks in one click

@TfTHacker Lovely 😍

The productivity bottleneck is now ideation, not creation

But if you never link ideas together, never reflect, never create something new from what you captured... you just built a prettier bookmarks folder. The real value is in the connections.

Most people collect notes. Few people connect them. Collecting feels productive. You highlight, you clip, you save...

@freekmurze Cool. Are those settings persistent?

Looking for a nice way to tell your Claude Code instances apart? Use /rename and /color.

@EleanorKonik My little claw uses it. My research skills use it. Very cool 😎

CLI? MCP? API? Yessss

How I synchronize and backup my Obsidian notes: I use a combination of Git, Syncthing, and cloud storage. Each serves a different purpose. Losing your notes is losing your thinking. Protect them.

@kinginmotion @obsdmd @claudeai Clearly! Patterns are emerging :)

@dSebastien @obsdmd @claudeai Early days. Lots to learn! But yes, I’m speaking to mostly the system concepts of the Zettelkasten. True. I’m mostly interested in how it can help us to create. :)

Been quiet for a bit, but... @obsdmd x @claudeai x Zettelkasten Playing around with these the last few weeks (It's so FUN). One thing became obvious fast... The zettelkasten is the perfect architecture for an LLM.

@gumroad @shl Tailwind FTW

Gumroad is now fully on Tailwind. We deleted our entire custom CSS design system and we're never looking back. New contributors and AI agents can ship UI changes so much faster now.

I've built over 60 AI skills to manage my knowledge base: Maintenance, Linking, Tagging, creation, cleanup, deep thinking, research, exploration, CRM, sales, marketing, productivity etc. Such a pleasure to use!

Context switching is not an idempotent operation. When your brain switches tasks, it "loads" data from memory. But our memory is unreliable. Each reload is different. The more you switch, the more context you lose. And it never comes back the same way. Protect your focus like your most valuable asset. Because it is.

Introducing the Readwise CLI. Anything you've saved in Readwise (highlights, articles, PDFs, books, youtube, newsletters) is now instantly accessible from the terminal. For you, and your AI agents. npm install -g @readwise/cli
