RAG, Graph RAG & Agentic RAG: How AI Retrieves and Uses Information

A language model does not know your internal documents, and it does not know what happened after it was trained. Retrieval is how you close that gap.

Terms covered:
– Information Retrieval: finding relevant content from a large collection in response to a query
– RAG (Retrieval-Augmented Generation): retrieve relevant documents at the moment a question is asked, then generate a grounded answer from them
– Graph RAG: uses a knowledge graph to retrieve, so the system navigates relationships between entities instead of matching keywords
– Agentic RAG: treats retrieval as active reasoning. It rewrites queries, routes across sources, checks whether results are useful and retries when they are not.

Standard RAG for direct queries. Graph RAG when relationships matter. Agentic RAG when the retrieval itself needs to reason.

Add RBAC to Your AI Agent: MCP Gateway + Auth0 + Apache Cassandra

Same chatbot, same question, two different answers, because two users have two different roles. In this tutorial, we add Auth0 login, three distinct roles, and a new Apache Cassandra backend to the MCP Gateway shoe store support chatbot, so each persona gets exactly the tools their job requires. No more, no less.

This is a follow-up to our first MCP Gateway video. If you haven’t seen it yet, start there for the base setup (HTTP + Kafka backends) before diving into this one.

Ubuntu is Going to Push Kernel Updates EVERY WEEK Now! (What Could Go Wrong?)

Ubuntu is Going to Push Kernel Updates EVERY WEEK Now! (What Could Go Wrong?)

Ubuntu is making a major change to how it delivers Linux kernel updates. Canonical is moving toward approximately WEEKLY Ubuntu kernel releases, replacing the existing 4/2 Kernel SRU model with overlapping two-week update cycles.

But why does a stability-focused Linux distribution suddenly need kernel updates every week?

In this video, we break down what Ubuntu’s new weekly kernel update strategy actually means, how Canonical plans to keep roughly two weeks of testing while releasing updates every seven days, and why this does NOT mean Ubuntu is becoming a rolling-release distribution or shipping a completely new Linux kernel version every week.

We also look at the huge explosion in Linux kernel CVEs. Kernel CVE counts jumped from only a few hundred per year to thousands after the Linux kernel became its own CVE Numbering Authority in 2024. Does that mean Linux suddenly became dramatically less secure? Not exactly.

We’ll also explore how AI-assisted security research is changing Linux kernel development, why AI is finding more potential bugs, and why human maintainers, backporting, verification and regression testing may increasingly become the real bottleneck.

And most importantly: what does all of this mean for your Ubuntu PC?

We cover:

• Ubuntu weekly kernel updates explained
• Canonical’s new Kernel SRU release schedule
• Why Linux kernel CVEs exploded
• Linux kernel security and CVE tracking
• AI-assisted Linux kernel bug discovery
• Ubuntu 24.04 LTS kernel updates
• Weekly kernel updates vs rolling releases
• Whether Ubuntu users will need to reboot every week
• Ubuntu Livepatch and kernel security fixes
• NVIDIA drivers and weekly kernel updates
• DKMS and out-of-tree kernel modules
• Kernel regressions, Wi-Fi and hardware problems
• Booting an older Ubuntu kernel if an update causes problems
• Whether faster kernel releases could affect Ubuntu stability
• What Canonical’s new strategy means for the future of Ubuntu Linux

Ubuntu says the testing process remains intact, with overlapping pipelines allowing one kernel candidate to be tested while the next one is already being prepared. The real question is whether Canonical can maintain the reliability Ubuntu users expect while increasing kernel release frequency this dramatically.

If you use Ubuntu, Ubuntu 24.04 LTS, Linux Mint, GNOME, NVIDIA on Linux, or simply follow Linux kernel security and desktop Linux development, this is a major change worth understanding.
