Not a fan of Knowledge Graphs, but recently I started using them more often for a surprising reason: to build non-trivial private verifiers for agentic search. For those who don't know, building a private eval set for a scaffolded LLM in 2026 is really challenging, like seriously hard. It...

Build better RAG by letting a team of agents extract and connect your reference materials into a knowledge graph. Our new short course, “Agentic Knowledge Graph Construction,” taught by Neo4j Innovation Lead Andreas Kollegger, shows you how. Knowledge graphs are an important way to store information accurately but they are a lot of work to build manually. In this course you’ll learn how to build a team of agents that turn data– in this case product reviews and invoices from suppliers–into structured graphs of entities and relationships for RAG. Learn how agents can automatically handle the time-consuming work of building graphs — extracting entities and relationships (e.g., Product "contains" Assembly, Part "supplied_by" Supplier, Customer review "mentions" Product), deduplicating them, fact-checking them, and committing them to a graph database — so your retrieval system can find right information to generate accurate output. For example, you can use agents to help trace customer complaints directly to specific suppliers, manufacturing processes, and product hierarchies, thus turning fragmented information into queryable business intelligence. Skills you’ll gain: - Build, store, and access knowledge graphs using the Neo4j graph database - Build multi-agent systems using Google’s Agent Development Kit (ADK) - Set up a loop of agentic workflows to propose and refine a graph schema through fact-checking - Connect agent-generated graphs of unstructured and structured data into a unified knowledge graph This course gets into the practicum of why knowledge graphs give more accurate information retrieval than vector search alone, especially for high-stakes applications where precision matters more than fuzzy similarity matching.

Building an Agentic Search System Building an agentic system is not too hard. Loops, function calling, tool execution, and the model. That's it! I show in this video how to build a search agent from scratch. ~350 lines of code!

In a recent interview, Howard Stern asked celebrated singer-songwriter Paul Simon a deeply personal question: “Is there a God? Because I need to know. I’m getting older. Is this it for me? Am I going to die, and that’s it? Or am I going somewhere?” Then Howard added, “Please answer this in a serious manner.” That’s a really important question—one that everyone should eventually ask. And I want to give an answer. Not my answer, because my personal opinion isn’t any more or less important than anyone else’s. What matters is God’s answer to that question, and we find it in the pages of the Bible. Check out this video..

Queer theorist Judith Butler attempts a response to Matt Walsh's "What Is a Woman?" and it's just "You're angry and you hate Socrates" "I can't help noting that the people who pound the table like, 'It's a simple fact, we should have a simple answer.' They're angry. They're insistent. They're frustrated. I mean, just look at what the emotional aura is of that claim. 'We need a simple truth.' And like, whoa, why are we so angry about that?" "I ask the same question. What is a woman? Freud asked the question: what does a woman want? But you could also say, what is a woman? My own sensibilities say it's a great question, but it's wondrous. It's wonderful. Let's keep that question open, because you know what? There are going to be a lot of different ways of answering and will give us access to human complexity. And then we'll know more about the world and we'll be able to affirm the human in its complexity rather than putting it into fixed boxes and smashing in those nails. So for me, 'What is a woman' is a great question, but I would just keep it open." "This is a movement that seeks to control knowledge, to suppress knowledge, to stop us from questioning -- even to attack Socrates, who taught us the absolute importance of open inquiry." "The anti-gender ideology movement is an attack on knowledge and an attack on open inquiry."

A DoorDasher left someone's order in a parking lot so a guy from one of the buildings decided to try and find out who it belonged to. I don't know what the policy is when you can't find the person but leaving it in a parking lot is probably not on the list.

Engineers and salespeople think in completely different ways. - Engineers: "If you ask them a question, a hundred percent of them will try and think of what is the correct answer to that question." - Salespeople: "If you're a salesperson, your first thought isn't: what's the answer? It's: why are you asking me that question?" "And so if you have an engineer talking to a good sales guy, it's going to upset them. Because they're often not gonna answer the question." "The guys who are good at the job get rejected, because you don't like them. And then the people who are terrible at it, those are the ones that ended up getting hired." "These CEOs just wanna take a guy who failed the engineering test, put a clean shirt on him and make him the head of sales." benahorowitz.eth with Brian Halligan

.Elon Musk (worth $250B) answers why he’s still working: I think it's a good question you asked, because it goes to, like, at a foundational level, what is my philosophy, and why does it lead to this conclusion? So the reason is that when I was a teenager, I had, like, an existential crisis to try to figure out what's the meaning of life. There doesn't seem to be any meaning. For me, at least the religious texts, and I read all of them that I could get my hands on did not seem convincing. Then I started reading the philosophers. Be careful of reading German philosophers as a teenager. It's definitely not going to help with your depression. So reading Schopenhauer, Nietzsche, as an adult, it's much more manageable. But as a kid, you're like, “Whoa.” So then I was like, “Man, I'm just struggling to find meaning in life here.” And then I read Hitchhiker's Guide to the Galaxy. And basically what Douglas Adams was saying is that we don't really know what the right questions are to ask. The question is not, “What's the meaning of life?” In The Hitchiker's Guide to the Galaxy, Earth it turns out is a big computer, and its goal is to answer the question, “What's the meaning of life?” And Earth comes up with the answer “42”. This is where the 42 number comes from. And 420 is just ten times 42. In that book, which is really sort of a book about, it's an existential philosophy book disguised as humor. They come to the conclusion that, no, the real problem is trying to formulate the question. And to really have the right question, you need a much bigger computer than Earth. And so maybe one way, I think, of characterizing this would be to say, “The universe is the answer. What is the question? Or what are the questions?” The more we can expand the scope and scale of consciousness, the better we can understand what questions to ask about the answer that is the universe. The more we can expand consciousness, become a multi-planet species, ultimately a multistellar species… we have a chance of figuring out what the hell is going on. And so this is why I think we should have more humans and both biological and digital consciousness. And why we should become a multi-planet species and a multistellar species is so that we can understand the nature of the universe. And then in order for that to occur, then we have to make sure that things are good on Earth. We don't want Earth to disappear, so sustainable energy is important.

I added a Knowledge Graph to Cursor using MCP. You gotta see this working! Knowledge graphs are a game-changer for AI Agents, and this is one example of how you can take advantage of them. How this works: 1. Cursor connects to Graphiti's MCP Server. Graphiti is a very popular open-source Knowledge Graph library for AI agents. 2. Graphiti connects to Neo4j running locally. Now, every time I interact with Cursor, the information is synthesized and stored in the knowledge graph. In short, Cursor now "remembers" everything about our project. Huge! Here is the video I recorded.

Knowledge graphs for representing information are unbeatable. After this, you will never build a RAG system without knowledge graphs. It will take you five lines of code to build a knowledge graph with your data. I recorded a video to show you how you can do this. I used Cognee, an open-source library that outperforms any basic vector search approach in terms of retrieval relevance. They are collaborating with me on this post. Cognee is: • Easy to use • Reduces hallucinations • Open-source Here is a link to the repository: They also offer a comprehensive platform and UI with Python notebooks you can utilize to manage your data. Here is the link:

✨ To inspire more people to go build something now that we have AI to help us (especially non-tech people, cause I still know so many who are scared of building something): I added a [ BUILD IT ] button to It's like a mini-Lovable/Replit/v0: Any idea you see you like, you can click [ BUILD IT ], and it will use Opus 4.6 to build a landing page for it And then you can download the code it generated It's not a full startup of course, but a nice preview of what it can be, to give you an idea and inspire you to build it out further The code is live streamed also so you can see it being built 😊 Ironically this itself took me 1 hour to build with AI too Completely free and I pay for the tokens (please don't abuse it :D)

Great balance of showing compassion while sharing truth as Wes Huff responds to the question of why a good God would allow evil: "Well, that is arguably the hardest and most pressing apologetic question there is, because ultimately, the very tidy philosophical and theological answer isn't the right answer sometimes. You know, sometimes the right answer to the wrong question is the wrong answer, because I've encountered situations where someone has brought up a variation of the problem of evil to me, and I've just felt uneasy about maybe the tenor that they're coming at with the question...and asking them, 'You know, that's a great question. Why are you asking that question in particular?' and finding out once again (like the previous question related to it), they're personally hurting. And so, in that sense, I could give a tidy answer about if you're positing that something is good, you're positing that there's an objective good and evil, and if there's an objective good and evil, then you're positing an objective law, and objective law needs an objective lawgiver. So where do we find the groundwork for an objective lawgiver to begin with? Otherwise, you may not like certain things, but to say they ought not to happen is actually an ethical leap to an objective reality that you may or may not have groundwork for. But if that person is struggling because a family member of theirs has cancer, then that particular, maybe tidy, tied-up-in-a-nice-bow answer is not going to speak to them whatsoever. And so that's why that's the hardest question because there are actually very good answers to it, but often it doesn't speak to the person in front of you, because questions have questioners that sit behind them. And one of the pitfalls of my chosen field of ministry apologetics is that sometimes we give answers where we talk at people rather than with people. And there's a danger to that because the Christian faith isn't just an intellectual assent, right? It's a personal relationship. And that should also be played out in the answers that we give..."

And you shouldn’t ask it. You shouldn’t even be asking it. It’s one of so many different things. It’s not high on the list, but it’s one of so many different things. And I can change my mind in seconds, but, you know, for you to ask the question — who would answer a question like that? You’re asking me a question. Kharg Island. Who would ask a question like that and what fool would answer it? Let’s say I was gonna do it or I wasn’t gonna do it, what would I tell you? ‘Oh, yes, Brian, I’m thinking about doing it. Let me let you know what time and when it will take place.’ It’s not — you know, it’s sort of a foolish question. A little surprising for you because you’re a smart man.”

2024 has given us a lot to reflect on. We are forever reminded that a field is never just a field. Because we know we are building more than an athletic facility. It means more to your community, so it means everything to us. Together, we’re building something. Thank you for being a part of it. Where you find passion You also find community A place where people can come together and believe A place for people with something to prove A place for unity and rivalry For triumphs and tragedy For breaking barriers and shattering ceilings Where everyone is on the same team…even when they aren’t Where impossible is made possible all of the time How does a place like this even exist? Where do you find it? The truth is…you don’t find it. You build it.
