1 Neural Network + Obsidian + Karpathy’s 1-file method = the most unhinged second brain build of 2026.

It remembers everything you’ve ever done, and it costs $0 on top of what you already pay.

The base is Karpathy’s append and review: 1 giant note, new thoughts stack on top, old ones sink, every few days you reread and pull the survivors back up. No folders, no tags, no plugins the rereading IS the system, because review is what turns storage into thinking.

The flaw: past 10,000 lines, no human rereads anything.

That’s where the neural network takes over.

You keep the note in Obsidian 1 vault, everything dumps to the top: ideas, links, meeting fragments, half-thoughts. You never organize, you only dump. It all lives as plain markdown on your own disk, and that detail is the whole trick.

Because now you point Claude Code at the vault folder, and it reads every line you’ve ever written. “What did I think about pricing in March.” “Find the 3 ideas I keep circling.” “What did I drop that deserves a second look.” It answers from YOUR notes, with quotes, in 15 seconds.

Then once a week, 1 prompt closes the loop: read the last 7 days, surface the 5 entries worth pulling back up, flag anything that contradicts what I wrote a month ago. The model does the sinking and surfacing Karpathy did by hand, and the note stays alive instead of turning into a graveyard.

Week 1 feels like nothing.
Week 4 you hit the first “I already solved this in January.”
Month 3 you consult your past self more than Google.

Most second brains die in 11 days under 40 plugins and 200 folders. This one is 1 file and a loop, and it compounds because dumping takes 0 discipline.

Notion stores what you thought. This thing argues back.

"Can it run DOOM?" was a joke for 30 years.

A petri dish full of human skin cells just said yes.

Cortical Labs trained 200,000 human neurons (!) to play the 1993 FPS game in a week:

tl;dr persona kyc and openai are frens, using your selfie for verification and sending to ICE (or USGOV in general), using AI to tie to your financial records. see subsequent post for full write-up. its long and not mobile friendly

@VishakhRanotra @grok what trade show is this

[Josh Johnson @secondfret]

No, grandma, you gotta self-host deepseek. Just run it local grandma. Get LM Studio. Groq will have it soon. Don’t worry about it. No, don’t short Nvidia. HODL grandma. Ok love you too.

Privacy wins. Today the Fifth Circuit held that @USTreasury’s sanctions against Tornado Cash smart contracts are unlawful. This is a historic win for crypto and all who cares about defending liberty. @coinbase is proud to have helped lead this important challenge. 1/6

Privacy is normal.

Railgun uses the privacy pools protocol ( https://t.co/DekkatsMR5 ) which makes it much harder for bad actors to join the pool without compromising users' privacy.

This is wild. The feds busted an AFRICOM drug-trafficking ring, run by Fort Bragg soldiers, that was moving enough ketamine from Cameroon to Fort Bragg to send tens of millions of people down a K-hole.
