I genuinely don't understand why everyone isn't using this yet
Andrej Karpathy, a co-founder of OpenAI, posted a simple idea that hit 16 million views: stop using AI to write code, use it to build a second brain.
You point Claude Code at a folder, drop in any source, an article, a transcript, a PDF, and Claude reads it, links it, and files it into a living wiki of everything you know. It compounds like interest, the more you feed it, the smarter it gets.
Here's the whole thing:
> Install Obsidian, create a vault, open it in Claude Code
> Paste Karpathy's wiki idea file and tell Claude to build it
> Claude makes three folders: raw for sources, wiki for its pages, a CLAUDE.md that runs it
> Drop any source into raw and say "ingest this"
> Ask questions across everything, forever
Five minutes to set up, and you never start from a blank chat again.

@mikker Thanks for making this beautiful app. I just have few concerns. The beautiful square doesn't show up when I hold modifier key to trigger Leader mode. I wonder why not. And could you please add an option to automatically show cheatsheet instead of pressing "?".
i can't believe nobody caught this.
Anthropic's entire growth marketing team was just ONE PERSON
(for 10 months, confirmed)
a single non-technical person ran paid search, paid social, app stores, email marketing, and SEO for the $380B company behind claude
here's exactly how one human is doing the job of a full marketing team:
it starts with a CSV.
1. he exports all his existing ads from his ad platforms along with their performance metrics (click-through rates, conversions, spend, etc)
2. feeds the whole file into claude code
3. and tells it to find what's underperforming.
claude analyzes the data, flags the weak ads, and generates new copy variations on the spot
this is where he gets clever:
he then splits the work into 2 specialized sub-agents:
1. one that only writes headlines (capped at 30 characters)
2. and one that only writes descriptions (capped at 90 characters).
each agent is tuned to its specific constraint so the quality is way higher than cramming both into a single prompt
so now he's got hundreds of fresh headlines and descriptions.
but that's just the text.
he still needs the actual visual ad creative, the images and banners that go on facebook, google, etc.
so he built a figma plugin that:
1. takes all those new headlines and descriptions
2. finds the ad templates in his figma files
3. and automatically swaps the copy into each one.
up to 100 ready-to-publish ad variations generated at half a second per batch.
what used to take hours of duplicating frames and copy-pasting text by hand
so now the ads are live.
the next question is which ones are actually working.
for that he built an MCP server (basically a custom integration that lets claude talk directly to external tools) connected to the meta ads API.
so he can ask claude things like:
• "which ads had the best conversion rate this week"
• or "where am i wasting spend"
and get real answers from live campaign data without ever opening the meta ads dashboard
and the part that ties it all together and closes the loop:
he set up a memory system that logs every hypothesis and experiment result across ad iterations.
so when he goes back to step one and generates the next batch of variations...
claude automatically pulls in what worked and what didn't from all previous rounds.
the system literally gets smarter every cycle.
that kind of systematic experimentation across hundreds of ads would normally need a dedicated analytics person just to track
the numbers from the doc:
ad creation went from 2 hours to 15 minutes. 10x more creative output.
and he's now testing more variations across more channels than most full marketing teams
a $380 billion company.
and their entire growth marketing operation (not GTM) = just one person and claude code lol
truly unbelievable
It’s strange that it only takes one moment at the end of November for my feeling to be gone. When I woke up a few days later, I felt something was no longer there. It was so sudden that it makes me wonder is it normal for things to progress like this? Things have never been the same since.
I try fly high and she snaps me back to the surface. I try looking at the world with optimistic eyes because the world doesn’t need one more pessimistic character and she slaps me in the face for trying to be the Kien back then, the Kien with the positive mind she once told me she missed. It might be the time I stop running away from the truth that I have a crazy mind and not everyone likes my ideas.
There seems to be an invisible wall between us. It’s like we’re living in different worlds, seeing things differently. I remember she used to be sweeter, softer, more pleasant towards me.
I try finding the feeling i lost, but it hasn’t comeback, at least to the present. Losing it feels like losing a precious person who has been with me forever, even though she’s still here. Emptiness and sorrow fill my head. Wandering around the city during break time, without knowing where I wanna go, became my habit.

@Freewell_Gear The 1.7x telephoto lens has 58 mm front thread. Does that means I could use any 58 mm filters from different brands with this 1.7x lens?
@matter It seems the app now requires iOS 26 as minimum. I don't mind it but when I updated the app on macOS Sequoia and opened it, it says my macOS version isn't supported, even though App Store page says it only requires macOS 14 or later. And I can't go back to older version to use it
I thought you made your mind up about this issue. Despite mixed signals, despite the possible outcome, I have to say it, I want to say it, I want to hold her close. But every time I meet her, I’m incapable of
https://t.co/ueKH4zgCAS
I miss you. My heart is alive once again after I met you. For the past few months, I ran away from this feeling. And it somehow works. My mind and my heart have stopped looking for her for a while. The stress from work helped me a lot in not thinking about her.
My heart wakes me up in the morning to think about you. Taking advantage of unanswered questions and responsibilities I have to do, I was actively hiding from her, I think. Why, I don’t really know. I’m confusingly complicated that sometimes I don’t even understand myself.
I hope laying bare everything in front of my eyes like this is better than keeping this mess of thoughts in my head. There’s so much work and personal stuff I have to do and I don’t want these thoughts to affect my motivation again.
Let’s break down the root causes of my sorrow happened lately. Let’s clean up this mess.
1. What are my thoughts that gradually build up this sorrow?
- I’m afraid that there might be a vision I won’t be with her in the future.
- I wish to be her life partner but what if she sees me as an inappropriate partner.
- She being with another man is my worst nightmare.
5. How can I break the circle?
- Stop overanalyzing and start thinking less about her feeling towards me, obviously. She doesn’t hate you as you think. Just look at the way she acts around you when we meet.
- Continue finding excuses to text her every day to keep sorrow away.
- When her messages feel off, don’t jump to conclusion right away. Remember, texting can’t convey our true emotion fully.
- Just go outside and have a happy picnic. If it rains, rearrange the schedule to an another sunny day. It can’t rain constantly for a whole week, or even a whole month.
- Whether she loves me or not, I can’t solve this question. I could try bringing her joy, show a bit of care for her but not too much to be annoying. Hit the gym more frequently, improve my look. Work harder to earn more. Speak better.
- But at the same time, I have to prepare to accept the truth and move on when necessary. It’s hard but you aren’t a kid anymore. Where are my hobbies that I usually do before I fall in love with her? Is there anything new emerges after?
