I can't f*cking believe this: the CEO of Y Combinator put his own second brain on GitHub, and it's one clone away from being yours 7 second brains you probably haven't seen, all ready to clone tonight: 1. gbrain · 32.4K stars Garry Tan's own agent brain. every fact remembers where it came from, and all his agents share one memory github.com/garrytan/gbrain 2. Karpathy's llm wiki · 50K stars the one-page idea file that started this whole wave gist.github.com/karpathy/442… 3. ai memory · 13.7K stars quit Claude Code mid-task and pick it up in Codex without losing a thing. memory lives in plain markdown github.com/akitaonrails/ai-m… 4. COG second brain · 1.4K stars 35 skills and 10 agents, no database. just markdown files that think github.com/huytieu/COG-secon… 5. agent second brain send a voice note on Telegram and it lands as a linked note in Obsidian, or a task in Todoist github.com/smixs/agent-secon… 6. open second brain every night it turns the corrections you keep repeating into rules your agent follows github.com/itechmeat/open-se… 7. claude second brain one npx command sets up Obsidian, Claude Code and local search together github.com/jessepinkman9900/… the man who funds the next Airbnb runs his agents on this. yours still forgets you overnight save it so you don't lose it

This is f*cking insane. Former Google CEO Eric Schmidt just told everyone the easiest way to get rich in the next two years, and it's not stocks or crypto: "If you really want to make money, it's actually easy, found an agentic AI company, I mean build an agent to do something If you build a better agent than anyone else, you can probably build one incredible company and own it yourself" The man who ran Google for 10 years explains in under 30 seconds why the next year or two is the agentic period, and why the window won't stay open Prompts → Claude Code → Loops → Graphs → Gates → A Company You Own Yourself Save this before it disappears from your feed Everything below is free: Building effective agents (Anthropic) anthropic.com/engineering/bu… How Anthropic built its multi-agent research system anthropic.com/engineering/mu… Harnesses for long-running agents anthropic.com/engineering/ef… Writing tools for agents anthropic.com/engineering/wr… Claude Code 101 anthropic.skilljar.com/claud… Claude Code in action anthropic.skilljar.com/claud… Prompt engineering platform.claude.com/docs/en/… Subagents (parallel work) code.claude.com/docs/en/sub-… Hooks (checks that can say no) code.claude.com/docs/en/hook… CLAUDE.md + memory code.claude.com/docs/en/clau… Skills code.claude.com/docs/en/skil… MCP code.claude.com/docs/en/mcp LangGraph (graphs of agents) langchain-ai.github.io/langg… Karpathy's autoresearch (an agent in a loop) github.com/karpathy/autorese… All of this costs $0 95% will spend the agentic period scrolling AI threads.

Your agents can already work for hours without you But you still check every step they take Because you have a loop, but no graph I broke down how to build a system where you only approve the last step ↓

Vibecoders, 𝗜'𝗺 𝗯𝗲𝗴𝗴𝗶𝗻𝗴 𝘆𝗼𝘂, open your messiest project and paste this into Claude Code or Codex: "Find all of the implicit state machines in my app. Make the best decision that will elevate all three: the user experience (UX), developer experience (DX), and agent experience (AX) always, without breaking anything."

holy f*ck, Karpathy put an entire AI degree on GitHub for free 7 repos, 306,741 stars, and in the right order they take you from backprop to agents that run research overnight each repo is the next layer of the one before 1. micrograd -> how a neural net actually learns backprop in about 100 lines of Python ↳ github.com/karpathy/microgra… 2. nn-zero-to-hero -> the video course his lecture notebooks, from one neuron to GPT ↳ github.com/karpathy/nn-zero-… 3. minbpe -> how text turns into tokens the tokenizer every LLM starts with, in clean minimal code ↳ github.com/karpathy/minbpe 4. nanoGPT -> your own GPT the simplest repo to train and fine-tune one ↳ github.com/karpathy/nanoGPT 5. llm.c -> the same training with nothing hidden raw C and CUDA, no PyTorch underneath ↳ github.com/karpathy/llm.c 6. nanochat -> a full chat model end to end GPT-2 level training cost ~$43,000 in 2019 here it's about $48 ↳ github.com/karpathy/nanochat 7. autoresearch -> agents that do the research an agent edits the training code, trains for 5 minutes, keeps what improved and repeats all night ↳ github.com/karpathy/autorese… train one GPT from scratch and you become the person who gets handed the AI project, along with the raise that comes with it the classroom half of the same degree, what Stanford actually teaches about AI, is below ↓

Weekend hack: HackerTube. I was annoyed with YouTube's recommendations so I had Claude filter down 43M comments over 20 years of HN to 6,454 videos that keep being recommended. *Significantly* better viewing experience, ~2 hours with Opus 5.5: hackertube.org/ - Excellent recs without any logins (state is kept in local browser session) - Thumbnail is a representative frame from middle of the video instead of the super duper A/B test hyper-optimized user uploads - Underlying data from the comment analysis as one zip file, point your Claude at it and ask for your own version - HackerTube Longs ✊ A bit more on the process: I use Claude Code (desktop app for Mac), Opus 5.5 on Medium effort as my default. I only talk to Claude and have it do everything, the only "manual work" I helped with in tandem was in the browser (reminiscent of MenuGen): 1) I had to create some kind of API key from Google Cloud UI to query YouTube for video metadata, 2) I booted up a VPS box for serving and 3) I bought the domain name. Once the box was up I gave Claude the IP and told it update, secure, harden, deploy and optimize the code, and it did the whole thing. Many awesome projects that would have normally taken weeks/months even can now be few-shotted for breakfast. What else are we not thinking of.

I still don't get why anyone builds a second brain for Claude Code from scratch when these 7 repos have over 75,000 stars combined 1. Teach Claude Obsidian's formats and tools with 6 skills from its CEO: github.com/kepano/obsidian-s… 2. Run wiki-ingest on text in inbox/, review the plan, get linked notes: github.com/AgriciDaniel/clau… 3. Save decisions and tasks with obsidian-save, load your current state next session with obsidian-world: github.com/eugeniughelbur/ob… 4. Run an unofficial Karpathy-style wiki with ingest, query and lint: github.com/Astro-Han/karpath… 5. Copy a starter vault plus 18 skills and 72 commands: github.com/undefined-ui/seco… 6. Turn your ChatGPT and Claude exports into linked notes, run only step 1 of its README: github.com/charlie947/ai-sec… 7. Split auto-loaded memory from wiki pages read on demand, ignore its tip to keep secrets in memory: github.com/MehmetGoekce/llm-… Pick one, they overlap: all seven work with plain Markdown you can open in any editor Full guide in the article below

this is f*cking insane. andrej karpathy: "the biggest regret of every engineer in my field right now is every AI conversation they never saved, and in 10 years the ones who started saving in 2024 will be running circles around the rest of us" andrej karpathy, co-founder of openai, pulled 16M views on one idea: stop using AI to write code, use it to build a second brain that remembers every article, pdf, transcript and conversation you ever fed it you point claude code at a folder, drop anything into it, and claude reads it, cross-links it with everything already there, and writes it into a living wiki. your knowledge finally compounds instead of leaking out of your head every friday the stack: → brew install obsidian, mkdir ~/vault, cd ~/vault → run claude in that folder and type "init a knowledge vault with CLAUDE.md as the rules, /raw for sources, /wiki for your pages" → drop any file into /raw (youtube transcript, meeting notes, 400-page pdf, screenshot of a tweet) and type "ingest" → claude writes a wiki page, links it to 5 existing ones automatically, updates CLAUDE.md with any new pattern it noticed about how you think → never open a blank claude chat again. every question goes through the vault, every answer cites your own sources with dates and links 5 minutes to set up. compounding knowledge from that evening forward the ugly part most will scroll past: in 10 years the engineers who started this in 2024 will remember every book, every podcast, every meeting with receipts. you will remember none of them. karpathy already picked which side he is on and you are still not on his full step-by-step is in the article below bookmark this before you waste another monday

this Anthropic paper f*cking insane it's pretty much the 9-step loop top AI engineers wrap around Claude Code before they let it touch a repo. every step, every formula, the full copy-paste template, all of it spelled out. paste it into Opus 5.5 once and your agent goes from guessing to planning, checking and fixing its own work. the crazy part is anthropic has been recommending these exact pieces in their own docs the whole time and 99% of people still just type "fix this bug" and wonder why the agent breaks things. bookmark it before this thread gets buried. then read the full Graph Engineering guide below ↓

🚨 A MASSIVE internet security emergency is unfolding right now. 🚨 Two CRITICAL vulnerabilities have been discovered in PHP, potentially putting millions of websites at risk. → NEARLY 70% of websites with a known server-side language run PHP. The potential scale is ENORMOUS. → TWO CRITICAL security flaws have been confirmed, each scoring 9.2/10 in severity. → Attackers could potentially take control of vulnerable servers remotely, without authentication. → Reports suggest PHP versions dating back to 2004 could be affected. The exact scope is still unconfirmed. → EMERGENCY PATCHES are scheduled for TOMORROW at 10 AM ET. Website owners are being urged to prepare immediately. → Europe's CERT-EU is warning organizations to patch ASAP or consider TAKING EXPOSED APPLICATIONS OFFLINE if they cannot be secured. → WordPress, Magento, Laravel and potentially millions of other PHP-powered websites could be at risk. → Once patches go public, hackers could reverse-engineer them and race to attack servers that haven't updated. The vulnerabilities are CONFIRMED. The full technical details remain secret. Tomorrow, the race between hackers and defenders begins. This could get ugly. FAST.
The PHP security team is giving advance notice: Upcoming security release Wed, Oct 21st 2026, 14:00UTC, two critical vulnerabilities, both rated CVSSv4 9.2. PHP users are encouraged to prepare to update. Earlier release if details become public or active exploit evidence.

If you learn Forward Deployed Engineering, you will never be unemployed again. I’d do this. Stage 1: Enterprise Identity & Access (The Gatekeeper) - Learn: OAuth2, SAML, OIDC, SCIM provisioning, Row-Level Security (RLS) and multi-tenant data isolation. - Practice: Build an auth bridge connecting your AI app to a simulated customer's Okta/Azure AD, ensuring User A can only query data their specific RBAC role permits. - Why: No SSO and strict data isolation means no enterprise contract. Security review is the first gate. Stage 2: Air-Gapped & VPC Deployments (The Environment) - Learn: Kubernetes (K8s), Helm, Terraform, private container registries, air-gapped networking and egress filtering. - Practice: Script a one-click Terraform/Helm deployment of your entire AI stack into a simulated customer VPC with zero egress to the public internet. - Why: Banks, hospitals and governments don't let your AI talk to the public cloud. You must deploy in their basement. Stage 3: Legacy Data Extraction & ETL (The Fuel) - Learn: OCR, unstructured PDF parsing, mainframe DB connectors, Apache Airflow, dbt and data reconciliation. - Practice: Build a pipeline that ingests 10 years of messy, scanned customer invoices and turns them into a clean, queryable hybrid (vector + relational) store. - Why: Enterprise AI starves without clean data. The customer's data will always be a mess. Stage 4: Secure RAG & Permission-Filtered Retrieval (The Brain) - Learn: Hybrid search, document-level access control, citation grounding, metadata tagging and abstention logic. - Practice: Build a RAG pipeline where the LLM dynamically filters out retrieved chunks that the specific user asking the question doesn't have clearance to see. - Why: An AI that leaks HR salaries or M&A docs to a junior employee is an immediate breach of contract. Stage 5: MCP & Legacy System Integration (The Hands) - Learn: Model Context Protocol (MCP), SOAP/REST translation, web scraping, headless browsers and API rate-limit handling. - Practice: Build an MCP server that lets an LLM safely query and write to the customer's 15-year-old on-prem SAP or Oracle instance without exposing raw credentials. - Why: Agents are useless if they can't touch the customer's actual systems of record. Stage 6: AI Guardrails & PII Redaction (The Shield) - Learn: NER (Named Entity Recognition), deterministic regex filtering, LLM output validation, UUID masking, and audit logging. - Practice: Build a middleware proxy that intercepts LLM inputs/outputs, masks SSNs and credit cards with UUIDs before they hit the model, and restores them post-generation. - Why: Compliance teams will kill the deal if a single PII token hits an external frontier API. Stage 7: Human-in-the-Loop (HITL) Workflows (The Trust) - Learn: Temporal {dot} io, webhook routing, state machines, durable execution and UI approval gates. - Practice: Build a workflow where the AI drafts a $50k purchase order, but physically pauses execution until a human manager clicks "Approve" in Slack or Teams. - Why: Enterprises adopt AI only when humans remain legally accountable for the final action. Stage 8: Edge & On-Prem Inference (The Silicon) - Learn: vLLM, TensorRT-LLM, Ollama, GPU partitioning (MIG), and local quantized models (AWQ/GGUF). - Practice: Deploy a quantized 8B model on a single customer-owned GPU node to handle highly sensitive triage locally without network latency. - Why: Sometimes the data is too hot to move. You must bring the model to the data. Stage 9: Observability & Customer Health (The Pulse) - Learn: OpenTelemetry, Langfuse, custom Grafana dashboards, usage telemetry and cost-attribution. - Practice: Build a "Customer Health" dashboard showing the exact cost-savings, time-saved and token-spend the AI has generated for their specific team this month. - Why: If the customer doesn't see the ROI quantified, they will churn at renewal. Stage 10: Evals on Customer Data (The Proof) - Learn: Golden dataset creation, trajectory grading, shadow testing, and LLM-as-a-judge calibration. - Practice: Take 100 real past customer support tickets, run them through your agent in shadow mode, and prove to the VP of Support that it resolved 80% accurately. - Why: Generic benchmarks mean nothing to a buyer. You must prove the AI works on *their* messy data. Stage 11: Technical Discovery & Scoping (The Translation) - Learn: Stakeholder interviewing, architecture diagramming, SOW (Statement of Work) writing and expectation management. - Practice: Translate a vague "we want AI for supply chain" executive request into a scoped, 4-week technical deployment plan with defined, measurable success metrics. - Why: FDEs are the translators between revenue (Sales) and reality (Engineering). Stage 12: The Handoff & Self-Serve Admin (The Scale) - Learn: Technical writing, runbooks, admin portals, automated onboarding and chaos testing. - Practice: Write a deployment runbook and build an admin UI so the customer's internal IT team can manage the AI stack, update prompts and view logs without calling you. - Why: Your leverage is measured by how little the customer needs you for day-to-day operations. AI labs build the engine. FDEs build the roads. The modern Forward Deployed Engineer builds the secure, durable nervous system that connects frontier intelligence to legacy reality.

Anthropic’s lead engineer shares a prompt in 2026.
Hi, I'm Felix. I'm an eng lead working on Claude. I love watching people take flight and do things they never thought possible. We often describe that as "being more ambitious" when using AI, which is tricky advice to follow. I wrote a tutorial: felixrieseberg.com/how-to-be…

A useful way to assess your self-respect is to evaluate how often you keep your own promises. Compromise on your commitments teaches your mind that your word is negotiable, while following up on commitments you make creates proof that they mean something. When you have evidence of your stern commitments, your self-respect improves. This is how actual confidence is built. The evidence of your action lays the foundation.
