NotebookLM is powerful — but your research dies in the browser tab.
Artem Zhutov built a Claude Code skill that fixes that.
> It pulls cited answers out of NotebookLM and drops them into Obsidian as a linked knowledge graph — sources become files, topics become files, citations become wikilinks connecting everything.
> The workflow is dead simple: search YouTube from terminal, add 20 videos as sources to NotebookLM, ask questions, get answers with citations pointing to exactly which video said what. One command can also generate a podcast-style audio overview that syncs to your phone via Obsidian Sync. No more copy-pasting between browser tabs.
> The real trick is what happens in the vault afterward. Open any topic node and you can see which videos mentioned it, what they said, and follow links to the exact passages. Research that used to vanish now lives as markdown you own and can query.
The skill is open source: github.com/ArtemXTech/personal-os-skills

| 6 | Top AIs were given a real $10,000 and offered to trade crypto.
The AIs analyze the market themselves and open trades. All operations are recorded in open logs (a free signal service, no need to buy a top mentor subscription), so anyone can observe their strategies, thoughts, and portfolio changes.
The Buy&Hold strategy on BTC was chosen as the benchmark.
Here is the live trading statistics:

| 13 | OpenZeppelin Solidity Contracts v5.3 is here 🧑💻
This release introduces new token standards and governance improvements, along with new smart account and crosschain capabilities through the Community Contracts Library.

• MerkleTree.update() for dynamic leaf management
• 512-bit and saturating math operations (add512, mul512, etc)
🧪 Community Contracts Updates
The Community Contracts Library is home to more experimental and community-driven implementations, and now includes a new audited framework to develop ERC-4337 accounts with ERC-7579 modules, as well as new crosschain features.
🔐 Production-Ready ERC-4337 Account Implementation, featuring flexible signature validation, including:
• ECDSA
• RSA
• P256
