A STANFORD GUY POINTED CLAUDE CODE AT 11,400 OBSIDIAN... NOTES AND FOUND 214 ARGUMENTS HE'D HAD WITH HIMSELF 7 years of notes, 340MB of markdown, and a graph view that looked like a brain but never once thought. Every Sunday he opened the vault and every Sunday he closed it again. The second brain was a landfill with good lighting. So he stopped reading it and let something else read it instead. 47 lines of config, one instruction: find every pair of notes written 2+ years apart that contradict each other. 19 minutes on a 2021 MacBook Air, then 214 pairs. He had changed his mind 214 times in 7 years and caught himself doing it zero times. Then came the one that stopped him a note from March 2019, 62 words, sitting in a folder called "misc," describing the exact product he'd spent the last 5 months and $18,000 building a research doc around. He solved it in 2019, filed it, and forgot it existed. The vault never failed him, it stored all of it perfectly, it just had no way to speak. Now a cron job wakes at 6 AM, reads 40 notes, and writes 1 paragraph: here's what you believed then, here's what you believe now, here's the gap. He hasn't opened the graph view since. He didn't need a second brain, he needed the first one to answer back.show more

Anthropic didn't build his memory system. He built it... himself, and what you're looking at is the proof. Same source, no gatekeeping. The Obsidian CEO published it, anyone can install it. That's not a screensaver on his second monitor. It's his vault. Every point of light is a note. Every cluster is a project his AI already understands without being told again. He doesn't even touch the keyboard to move through it. One hand up, and the whole cluster tilts and spins, like he's turning a globe that happens to be his own head. A year ago he opened a new AI tab every morning and explained himself from scratch. Who he is, what he's building, what he wants. 200+ hours a year, just re-introducing himself to a machine. Then he stopped writing prompts and started writing one file instead. It loaded before every session. His goals, his projects, his blind spots. Claude read it first, every time, without asking. Now the cluster on that screen keeps growing on its own. New notes link themselves. Nothing gets explained twice. He's not showing off code. He's showing off the machine that finally stopped forgetting him.show more

YOUR OBSIDIAN VAULT READS ALL 2,000 NOTES TO ANSWER... ONE QUESTION. THAT'S NOT A SECOND BRAIN. That's a hoarder with markdown files. Hundreds of thousands of tokens burned per answer, and it still grabs the wrong note half the time. A real second brain runs on a graph: a router, an index, nodes, edges. Fable 5 reads 2-3 files instead of the whole vault. Answer back in under a second. The graph view everyone screenshots in Obsidian is a poster. The index is the actual engine. Full 11-step build below, from raw vault to working graph 👇show more

THIS MAN HASN’T HAD A SINGLE ORIGINAL IDEA IN... 8 WEEKS. CLAUDE HAS ALL OF THEM BEFORE HE WAKES UP he gave claude his obsidian vault on a saturday by monday it found a link between two notes written 6 weeks apart in different folders he turned that connection into his best-performing post his competitors are still organizing folders and writing morning pages and brainstorming in notion the only difference is one file called CLAUDE.md every note = fuel and every morning = synthesis and every week = ideas compounding faster than he can publish them this is not a tool anymore and this is not even an assistant this is a second brain that studied you for 2 months straight bookmark & like this or lose it forevershow more

25-year-old developer copied 6 years of his emails, client... calls and notes, pasted them into Grok Bot and told it to build a brain that thinks exactly like him. 20 minutes later - a complete second brain. Then he boarded a 3-day train across America with no Wi-Fi. In his backpack: a laptop and a $4,000 box the size of a sandwich running a 200B-parameter model. One Ethernet cable between them. The whole brain lived inside that box. Somewhere in Nebraska, zero signal, he typed “what am I forgetting?” It found 3 client follow-ups he’d dropped months ago, the exact price he’d quoted each one, and wrote every reply in his own voice. Sent them at the next station. Two paid before Denver. $6,400 from a train seat with no internet. Then he built a machine. The brain now reads every email and call as it happens, finds him new clients, writes his proposals, makes his decisions and plans his week. Zero cloud, zero subscriptions, nobody ever sees his data. Month one - $6,400 from a train. Month six - it runs his business for him Most people still use AI to fix typos in their emails. A second brain makes you money, remembers everything and solves problems before you even notice them, and almost nobody has built one yet.show more

This man was riding a bike with his wife.... He was already feeling unwell and had a bad cold. Suddenly, it started raining heavily on the way. He had only one raincoat. Even though he was sick, he didn't wear it himself. Instead, he gave it to his wife. He was shivering badly after getting completely soaked in the rain, but he still chose his wife's safety and comfort first. This is the life of a man. He endures every hardship himself but makes sure his wife and family never have to suffer.show more

They told you it was just an acceptance speech.... They told you to applaud and move on. But what if Jim Carrey didn't come to collect an award he came to deliver a verdict, and the silence that followed wasn't respect... it was shock. Here's what they don't tell you: Jim Carrey didn't just thank Hollywood, he indicted it. In a room full of stars, producers, and power brokers, he spoke a truth so dangerous the air left the building: Kidnapping children is not what great nations do. He didn't say it quietly. He declared it. And in that moment, the mask of entertainment slipped, and the monster beneath was named. That silence wasn't awe. It was tension. It was the sound of a system recognizing one of its own had broken the code. Celebrities aren't supposed to mention the unmentionable the trafficking, the corruption, the war crimes dressed as patriotism. Carrey didn't just cross a line. He erased it.show more

THIS IS WHAT YOUR SECOND BRAIN SHOULD LOOK LIKE... most people dump notes into obsidian and call it a second brain it’s not a second brain it’s a second drawer karpathy just dropped the pattern that changes this and it’s called the llm wiki every time you add a source ai reads it, extracts key claims, updates every connected note and flags contradictions your obsidian stops being an archive and starts being alive save this and show it to someone still using notion as a second brain full breakdown in the article ↓show more

STOP STORING NOTES. START COMPILING THEM. a pile of... notes isn't memory. it's accumulation wearing memory's clothes. these 7 repos build the other kind, where Claude reads a source once and links it to everything you already have. copy the list: graphify: turns a codebase with its docs, SQL schemas, configs and PDFs into a queryable knowledge graph. 127k stars Understand-Anything: maps a project's code, docs or wiki into a graph you can search and query from your coding assistant. 86k stars claude-obsidian: lets Claude Code build and maintain a Markdown knowledge base in Obsidian, with source-backed notes and grounded answers. 15k stars obsidian-second-brain: gives Claude Code long-term memory as plain markdown notes in an Obsidian vault. 4.8k stars claude-code-memory-setup: an Obsidian vault as persistent memory, graphs for your codebase, and a pipeline that saves insights from your chats. 1k stars second-brain: an Obsidian knowledge base the LLM maintains, built on Karpathy's LLM Wiki pattern. 727 stars llm-wikid: an agent compiles your raw sources into cross-linked wiki pages in Obsidian. 420 stars none of them is your second brain. they're the compiler. the brain is what you feed it pick one and feed it your first 50 sources. before that, a compiled wiki behaves like a plain search engine, so don't quit early. the full setup is in the articleshow more

An OpenAI engineer stopped me at a hackathon in... Hayes Valley I had my terminal open on a table. Three panels. Live trades scrolling. He was walking past and froze. "That's not a demo. That's a live scoring engine. What model is that" I told him. Claude Opus 4.7. Four repos. $25 a month. He pulled up a chair without asking. "We benchmarked Opus 4.7 internally. It beat o3 on structured reasoning across every eval we ran. And you're telling me you're using it to trade" I told him it does more than trade. It reads 86 million trades and finds who wins and why. No fine-tuning. No prompting chains. Just raw context. He leaned back. "Show me the data source" I opened one link. 86 million trades. Every wallet. Every entry. Every exit. "You point Opus 4.7 at this and it reverse-engineers the strategy. It finds the wallets that win. Then it finds why they win. Then it copies the pattern" His team spent 14 months building something similar. 10 engineers. Custom infra. Still in staging. "The part that killed us was exit timing. Every model we trained nailed entries. But the best traders exit before the crowd. We never figured out the threshold" I told him my bot cuts at 85% of expected move. Or on a 3x volume spike. Whichever comes first. He stopped talking. "How did you find that" Opus 4.7 found it in poly_data. Top wallets exit before resolution 86% of the time. Losers hold to 58%. Exits are the entire game. I opened another tab. "Three commands. 500 markets. Opus scores them in 20 minutes" "That's our internal eval pipeline. Except it took us a year and you did it in a weekend with our competitor's model" My setup: Claude Opus 4.7 - $20/mo VPS - $5/mo poly_data - free polymarket-cli - free 214 trades. 74% win rate. +$9,400 in 19 days. Copytrade here: I showed him the article where I broke down every repo and every command. He read it twice. Then looked up. "You just published what we've been trying to ship for six months. Using the other team's model" He texted me the next day. "My manager found your thread. Delete it" Too late.show more

A 17-year-old student spent $4,200 on 7 Mac minis.... Small silver boxes. Stacked on a desk. Connected in one room. From the outside, it looked like a stupid purchase. But inside, it wasn't just 7 computers. It was Skills. Hooks. Memory. Worktrees. One machine handled repeatable tasks. One ran checks automatically. One kept context between sessions. Others ran parallel jobs without touching each other's work. While most people were still typing the same instructions again and again, his setup was already moving. A lot of people pay $200 a month for Claude and still use maybe 20% of it. He built a system around it. Skills turned repeated work into reusable workflows. Hooks made actions fire automatically. Memory stopped every session from starting at zero. Worktrees let multiple tasks run at the same time without collisions. That changed everything. Setup time: under 1 hour once. Time returned: 3 to 5 hours every day. He spent $4,200 once. He made $16,000 in the first week. Not because he found a secret tool. Not because he wrote magical prompts. Because he stopped using it like a chatbot and started using it like infrastructure. 7 Mac minis. 1 student. $4,200 in. $16,000 out. And most people would still call it just a stack of computers.show more

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.show more

Winston had been returned to the shelter three times... before the Abbotts came for him. He was an old shar-pei, all wrinkles and gray whiskers, about 11 years old. Every family that took him home brought him back within a month. He was too old, too slow, and too set in his ways for most people. One family even said he was depressing to have around. By the time the Abbotts saw his photo online, the shelter staff had almost given up hope that anyone would choose him. Ray and Carol Abbott were in their late 60s and had just lost their own dog after 14 years together. Friends told them to get a puppy. Something young. Something with plenty of years ahead. Instead, they drove an hour to meet the old shar-pei nobody wanted. Carol says she knew the moment she saw him sitting quietly in the back of his kennel. That first night, Winston couldn't settle. He kept getting up to make sure Ray and Carol were still there. He'd walk to the bedroom, look at them sleeping, lie back down, then twenty minutes later he'd do it all again, as if he was waiting for someone to tell him it was over. Finally, Carol patted the foot of the bed. "Come on up, Winston. You're home now." He stood there for a long moment, almost like he couldn't believe she was talking to him. Then he climbed up slowly, turned around twice, and eased himself down against Ray's legs with a long groan that sounded more like relief than exhaustion. For the first time in months, Winston slept through the entire night. The Abbotts say he isn't going anywhere this time. And after being returned three times, Winston finally seems to believe them. Have you ever seen a dog realize it was finally home?show more

One second he was sitting peacefully on the steps,... and the next he was completely surrounded by a swarm of Golden Retriever puppies.

Warren Buffett used to read 5 to 6 hours... every single day. 5 daily newspapers. Magazines. 10Ks. Annual reports. He had been doing this for over 70 years. Most people want Buffett's returns without Buffett's reading habits. That's not how it works. "I just read and read and read." No system. No shortcut. No AI summary. Just hours of sitting with information, thinking about it, and letting it compound in your head the same way money compounds in a portfolio. The edge isn't the reading. It's what 70 years of reading does to your pattern recognition. He still reads slower than he did when he was young. He still does it anyway. Most people quit reading the moment they leave school. Buffett never stopped. That gap sustained over decades is the entire explanation for why he sees things other people miss.show more

MY GROK BOT / OBSIDIAN MESH SYNCS 20 AGENTS... ACROSS A LIVE KNOWLEDGE GRAPH. NOT ONE OF THEM REPORTS TO ME. I FIXED THAT BY HIRING A 21ST BOT WHO DOES NOTHING BUT ROUTE. i watched the mesh light up this morning. vector, canvas, oracle, extract, all 20 of them syncing notes. writing backlinks, healthy status, 190 edges active. it looked like a team. it was a graph. a graph has no chain of command, it just has connections. i had been treating 20 well-wired agents as oversight. they were routing information, not decisions. nobody in that mesh could tell me what mattered first. so i hired one more bot and gave him a different job. not indexing notes, holding the account. 1. Reports-to line in the charter › names me as the human above him, closes the drift where a bot starts acting like the principal instead of the agent. 2. no source, no number › if he can't cite where a figure came from, he leaves it out. the 20-agent mesh never needed this line. › Chief can't run without it. 3. stop list written as verbs › "sending anything to a person" instead of "communications." a verb he can match, not a category he can talk around. 4. Rule 6, approval belongs to the human › he never signs off on another bot's irreversible action, only i do. the mesh has no equivalent rule. › it was never built to approve anything, only to sync. 5. STOP ALL, the kill switch › one message halts every routine and every task he's running, reports what was in flight, and waits. the mesh will keep syncing whether i watch it or not. Chief is the only bot in the account who stops the second i tell him to. that's the difference between a graph that moves information and a bot that's actually accountable for it.show more

I gave my Obsidian vault a lawyer's brain and... now it argues with itself before it answers me three months ago I was drowning. 20 government acts, budget docs, constitutions, all sitting in my vault as dead markdown I could never actually query. so I stopped treating it like notes and built it a nervous system I turned it into a 10-node graph. every question I ask hits a router first. it decides in a split second: is this a greeting, is this garbage, is this vague, or is this real. greetings die for free. garbage gets rejected. and if my own question is too vague, the vault stops and asks ME to clarify before it wastes a single token then comes the part I'm proudest of. after it writes an answer, a second node reads that answer back against the actual chunks it pulled from my vault. if the answer isn't grounded in what I actually wrote, it kills it. my vault would rather say "I don't know" than lie to me. it physically cannot hallucinate I compressed 20+ dense documents into 15,408 chunks, cut the vectors by 75% so storage costs almost nothing, and cached everything so repeat questions come back in under 100 milliseconds I used to have a folder of files. now I have something that thinks before it speaks, checks itself before it answers, and refuses to make things up about my own life. that's the difference between storing knowledge and building a mindshow more

My dad called Sunday morning. Said he was in... the neighborhood. "Did you eat?" "No." "I'll grab bagels." He showed up an hour later. Sat at the kitchen table. Looked around. "So this is what you do all day." "Yeah." "What, you just code?" "Trading systems. Open-source. Anyone can see the code." He took a bite of his bagel. "So you code for free?" "No, dad. The code makes money." "Sure it does." I didn't argue. I opened my laptop. One wallet I was tracking turned $480 into $6,900 in 19 days. Another moved $5.3M in volume. One more had a 74% winrate across 214 trades. Sharpe 2.31. I didn't touch it once. He stopped chewing. "That's... from a script?" Exactly. Then I showed him the repos. All free. All public. First: 86M+ trades on Polymarket. Every outcome since day one. Free to download. Second: Market making bot. Both sides of the book. Gas optimized. Google Sheets execution. Third: ML + heuristics. I fed 14,000 wallets into Claude. One prompt. 4 minutes. Found 47 traders with 70%+ winrate. Bot mirrors them with 60-second delay. He went quiet for a long time. Then: "How long have you been doing this?" "Eight months." "And you didn't tell me?" I didn't have a good answer. Profile: Fathers don't ask about the money. They ask why you didn't tell them.show more

Sold 32 coins. Bought 1,550. 48 times more, at... a 15% discount, into the crash the market blamed on the sale. Strategy disclosed today that while everyone panicked over its $2.5 million Bitcoin sale, it was quietly buying the dip that panic created. 1,550 Bitcoin for $101 million, at $65,332 a coin, far below the $77,135 it sold for and below its own cost basis. The bears called the sale the first crack, a forced liquidation, the start of the death spiral. The answer was a buy 48 times the size of the sale that scared them. This is the machine we described: a state-contingent allocator. Above its funding line, it turns market access into Bitcoin. The sale was the exception. The buy is the rule. It also closed the question the sale opened. The cash reserve behind the preferred dividends had thinned to $900 million, about six months of cover. He rebuilt it to $1 billion in the same week. But watch how, because that is the real story. He funded none of it with coins. He funded it with $181 million of freshly issued stock, then spent it on Bitcoin and the reserve. The coins were never the funding source. The equity is. That is the flywheel working exactly as built, and the cost of it surfacing at the same time. Every turn now runs on issuing shares, and the premium that once made each share buy more Bitcoin than it diluted has compressed hard. He bought low. He sold his own stock low to do it. So the question quietly turns. It was never whether Saylor sells his Bitcoin. He just proved again that he buys far more than he sells. It is what each turn of the engine now costs in dilution, and how long the market keeps paying a premium worth that cost. He bought the dip. The dip was partly his own making. And he paid for it in equity, not coins.show more
