The "fluorescence" of AI: why the hype is blinding and what we keep forgetting
Patterns from Linux, cloud, and DevOps that repeat with every tech shift
Ideation hackathons: a structured approach to organizational AI adoption
Data provenance risks and why throwing tools at non-technical teams is dangerous
Buy vs. build: open weight vs. public models and the hybrid approach
"Code is the new assembler": will developers still write code?
AI model drift: what happens when a model upgrade breaks your application
Agentic AI, kill switches, and the efficiency-thoroughness trade-off

July 24, 2026Ep84: Relearning Streams and Lambdas + Offloading vs Surrender to AI
This week, hear the latest updates on writing the Java book and prepping meetup tours, as well as a thought-provoking article on developer cognition in the age of AI.
Deep dive into lambdas: concise, one-line rules for sorting, filtering, and transforming data
Streams explained: pipelines that apply lambda rules across collections of items
Lambdas + streams as examples of declarative programming vs. imperative for-loops
Writing progress update: caught up after a slow start framing the new chapter
Virtual meetup event! Happening next week for the Miami Java User Group. Join us!
Discussion of an article on cognitive offloading vs. cognitive surrender with AI tools (Cognitive Surrender by Addy Osmani)
Key point: while easier to copy/paste or let AI, we suffer without comprehension.
The "calibration question": are you forming your own view, or just adopting the AI's?
Takeaway: use AI to delegate and enhance your work, not to replace critical thinking

July 10, 2026Ep82: AI and Code Generation + Code Reviews in a Changing Landscape
Recap of my week, with several different topics where I expanded my knowledge or surfaced some recurring patterns in my efforts.
Highlights:
Repeated prompt iteration can cause LLMs to get stuck in unhelpful loops or produce slightly different code on reruns. Restoring to a checkpoint helps reset context and regenerate cleaner output.
A personal AI workflow shortcut: using chat models to brain dump and organize ideas into structure before writing.
Pet projects. Alongside expanding a Goodreads project, there's a potential new personal improvement app idea
Other tasks: session review for NODES conference, upcoming refresh work on a Knowledge Graph e-book, and plans for short-form video content.
Article: “Read Less, Steer More” by Ezyang on mentoring code reading, using LLMs to explain code, avoiding auto-accept edits, and writing code by hand when learning fundamentals.

July 03, 2026Ep81: Curating NODES 2026 + The Software Industrial Revolution
This week included reviewing abstracts for NODES developer conference returning this fall, making progress on the book, and other exciting things happening within the team.

Highlights:
Schedule for Neo4j’s free virtual NODES is in the process as we review and select sessions. Register now!
Progress on the Java book with an aggressive schedule that is challenging, but manageable.
Several colleagues are at the AI Engineer World’s Fair in California, so stop by to see them!
Neo4j launched a major refresh to the GraphAcademy site, featuring a new design, AI-forward learning features.
Hear my thoughts on Andy Coenen’s article “The Software Industrial Revolution". AI may reduce software costs, increase software consumption, disrupt monopolies, and potentially improve costs and experiences in areas like healthcare.

June 26, 2026Ep80: Rethinking AI Intelligence + Developer Careers After Code Generation
Wrapping up a busy week of GraphRAG training and book writing with two topics worth unpacking: what we actually mean when we call AI "intelligent," and what a recent article reveals about the shifting landscape for software developers.
AI models are pattern-matching algorithms. They appear intelligent only when humans surface the right context, not on their own
"Intelligent" is a term developers should use loosely and critically, not as a given
I ran a GraphRAG Fundamentals online workshop (code available) and is deep in writing her AI-first Java book
The article "Code is Cheap. Show Me the Talk" argues that LLM tools have fundamentally changed software development
AI-generated docs and READMEs make it harder to judge how much care an author put into their work
"Slop" has always existed in software. AI just makes it harder to spot
The biggest cost: junior developers are losing the learning path that built strong technical foundations
Senior devs have an opportunity to mentor the next generation differently
The hype around AI in development cuts both ways. It lowers barriers to building, but raises the stakes for intentional learning and craft. Worth thinking about wherever you are in your career.

June 12, 2026Ep79: Roie Schwaber-Cohen on Reducing Agent Token Costs + RAG Beyond Semantic Search
In this episode, I sit down with Roie Schwaber-Cohen, a software engineer and developer advocate at Pinecone, to talk about smarter ways to build with AI — without burning through tokens or your patience!
What we cover:
Why agentic AI systems burn so many tokens (and ways to combat it)
How Pinecone's Nexus pre-explores retrieval paths so agents don't have to discover them at runtime, cutting latency and token usage
The problem with naive RAG ("Franken answers") and why domain-level separation of your documents matters
How Pinecone Marketplace lets non-developers connect structured and unstructured data sources to build production-ready AI apps
Why semantic similarity isn't the same as correctness, and how document introspection helps agents ask better questions
