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.
Full step-by-step guide with Claude and Obsidian, link below.

A 21-year-old solo developer stopped chasing AI trends and locked in a $35,000/month B2B niche using a single Python script
He built a production-ready traffic monitoring Micro-SaaS that smart cities and businesses pay big money for
He didn't build complex AI agent teams
He just paired an open-source model with a high-ticket commercial concept
Every single day, his system follows a military-like routine: tracks the bounding boxes, calculates telemetry, and locks in the data
For 4 to 6 steps straight, the pipeline is completely optimized. Zero frame drops, zero lag. Just pure automated tracking under the hood
He doesn't even use raw screen pixels for calculation to keep his speed metrics clean from perspective distortion
Out of 6 core features he launched, 3 handle the baseline detection and tracking using YOLOv8, Supervision, and ByteTrack
But one single feature (Perspective Transform via OpenCV) converts pixels to real meters and generates high-value Excel traffic reports for clients
His main secret? He utilizes a custom Polygon Zone to filter out noise and ships a ready-to-sell B2B product immediately instead of overcomplicating the setup
MIT defines an algorithm in one sentence that changes how you think about trading
"a computational procedure that takes an input and produces an output through a well-defined sequence of steps"
that's it. not AI. not machine learning. not a black box
a set of rules that takes data in and spits a decision out
every quant strategy ever built is just an algorithm
Citadel's execution system that routes 40% of US equity volume is an algorithm
Renaissance's Medallion Fund running millions of trades per year is an algorithm
Jane Street's market making engine processing $26 trillion annually is an algorithm
input: market data
rules: mathematical conditions
output: trade or no trade
the difference between a quant desk and a retail trader is not the data
it's that one side wrote down their rules precisely enough for a machine to execute them
retail says "if RSI is low and the chart looks good, i'll probably buy"
a quant desk says "if RSI < 30 AND 20-day realized vol < 15th percentile AND sector momentum z-score > 1.5, buy 0.3% of NAV"
same logic. one is a feeling. the other is an algorithm
the feeling can't be tested, can't be repeated, can't be measured
the algorithm can be backtested across 10,000 trades and you know exactly when it works and when it doesn't
> this lecture: MIT, free, 70 seconds
> algorithmic trading volume: 60-75% of all US equity trades
> Jane Street, Citadel, Two Sigma: every trade is algorithmically executed
> tools to build your own: Python, free data, a laptop
you don't need a faster computer or better data
you need to write your strategy down precisely enough that a machine could run it without you
that's the whole leap. from intuition to algorithm

🚨 THIS GUY JUST PLUGGED CLAUDE STRAIGHT INTO HIS BROKERAGE ACCOUNT AND REBUILT $99/MO INDICATORS IN MINUTES!!
No course. No bot promising 1000% gains. Not clickbait
Just a dude in a flag hat wiring AI into his trading workflow from his kitchen
The play: connect Claude to his account → ask it to recreate the indicators other people gatekeep and sell → done in minutes, not months
It sounds like cope until you clock what actually happened:
The secret strategy everyone's charging for? Rebuilt for free
The locked "DM me for access" indicator? Cloned on the spot
The edge was never the indicator, it's that nobody told you you could just build it
Five-minute setup vs a $99/month subscription that does less. That's the whole trade
His call: retail trading gets rewritten over the next 2-5 years. The ones putting in reps now eat. The ones waiting for it to get easy get left
Bookmark this! The edge is now a chatbot and the will to actually use it

🚨BREAKING: A new Python library for algorithmic trading.
Introducing TensorTrade: An open-source Python framework for trading using Reinforcement Learning (AI)
i have created a master loop harness that allows you to run perpetual mission loops that create goal loops that then spawn agent loops which then run their own workflow loops which finally run the tool loops.
i really wish i was joking 🙃

🚨 Hedge fund managers are going to hate this. Someone just open sourced a system that does their entire job.
30.5% annualized returns. $0 in fees.
It's called TradingAgents.
Not one AI agent. An entire simulated trading firm. Analysts, researchers, traders, and risk managers. All AI. All arguing with each other before making a single trade.
No Bloomberg Terminal. No $50K data feeds. No MBA required.
Here's what's inside this thing:
→ 4 AI analysts scanning financials, news, social sentiment, and technicals
→ A Bull and Bear researcher that literally debate each other
→ A trader that synthesizes every argument into a final call
→ A risk management team that can veto any trade
→ A fund manager that approves or rejects execution
Here's the wildest part:
It beat every traditional trading strategy they benchmarked. Cumulative returns. Sharpe ratio. Max drawdown. All of them.
Hedge funds charge 2% management + 20% performance fees for this exact workflow. This is free.
100% Open Source.

🚨 ANTHROPIC JUST PUBLISHED A 36-PAGE SECURITY GUIDE THAT BASICALLY TELLS YOU TO STOP TRUSTING YOUR OWN AI AGENTS.
If you run agents on Claude Code, MCP servers, or automation tools, pay attention.
The attack timeline has collapsed.
AI models compress the gap between a vulnerability and a working exploit from months to hours, for mere dollars.
Agents introduce new autonomous risks, from tool poisoning to context memory manipulation.
The most useful idea in the guide is Anthropic's new security test:
Does a control make an attack impossible, or just tedious?
Automated attackers have unlimited patience. They will grind straight through friction like rate limits and 2FA. To defend at the speed of AI, you need hard barriers and automated defensive operations.
Here is how Anthropic says you should lock down agents:
→ Treat static API keys as compromised. Use short-lived tokens that expire in minutes.
→ Apply "Least Agency": explicitly limit what each tool can DO.
→ Sandbox agents that process untrusted inputs like emails and web pages.
→ Scope permissions dynamically per task, not permanently.
I've added the link to the guide in the 🧵↓
A SENIOR GOOGLE ENGINEER DROPPED A 421-PAGE DOC THAT NO ONE IS TALKING ABOUT.
