Everything is on a continuum. But some continuums are more lopsided than others.

I'm gonna be at @bsidesdayton.bsky.social this Saturday running the Radio Village and talking about Reticulum. Wanna play with some radio? Want to build secure off-grid networks? Buy a ticket already. It's only $25 and they feed ya! bsidesdayton.com

CORE is an informal community for anyone enthusiastic or curious about radio—whether you're new to radio and want to learn or you've been tinkering for years and want to share. This month we have Radio Signal Analysis Using SDRs and OpenWebRX+ with Scott McCrory. Details are are core.radio.

And so it begins…

You probably haven't heard of the Reticulum Network. The tl;dr—it's an alternative network stack that's decentralized, encrypted, and runs on everything from Ethernet to LoRa radios to serial cables.

One of my goals is to own my stuff. I think a lot of people are tired of their data, their tech, and their network being controlled by centralized powers. I am one of those people.

I sometime banter with my AI. The smarter models have a pretty decent sense of humor. Or at least they stochastically fake one pretty well. Here's a fun little interaction with OpenClaw running GPT-5.1.

🎙️ @guy.dev is speaking at #StirTrek2026! "Agents & Arbiters - An Adventurer’s Guide to Multi-Agent Collaboration with LangGraph.js" 📅 1 May 2026 10:30 AM 🎟️ events.humanitix.com/stir-trek-20... We're really looking forward to having Guy at Stir Trek this year!

Chuck Norris doesn't rest in peace. Peace rests in him.

The first meeting for the Central Ohio Radio Enthusiasts is April 7. The topic is WiFi HaLow. Don't know what that is? I know how you can find out! RSVP. Join our Discord. Get on our mailing list for future events. How? It's all at core.radio. And shout out to our awesome host—@leadingedje.com!

International Women's Day is a fantastic thing to celebrate. May all the women in my life—and those not in my life for that matter—have a wonderful day. Of course, this year it landed on my birthday. So you'll forgive me if I also call it International Guy Day. Just this once.

Welp. What may have been obvious to others but not me is now official. I have ADHD. Now, gimme some Adderall!

LLMs can be unnecessarily verbose—loquacious even. So many bullet points just scrolling by. Most just ai;dr and move on. But when it's part of a workflow, it can break routing logic. The solution—structured output. Part 3 of Learning LangGraph.js shows you how to do it. medium.com/the-guy-wire...

I'll be on Eat Sleep Code today at 3pm ET to talk tech news with @edcharbeneau.bsky.social and John Bristowe. Will #AI come up? Will @redis.io? Of course! But I'll keep the hype to a minimum and focus on practical stuff that helps you build better apps. youtube.com/telerik

I'm starting a new meetup called CORE—the Central Ohio Radio Enthusiasts. It's for radio and radio-adjacent interests. It's not a ham radio club, we talk about that, but also GMRS, mesh networks like Meshtastic, Reticulum, and HaLow, software-defined radio, and shortwave listening.

So, I learned a new Internet abbreviation today: ai;dr

A replacement for HamClock, which will shutdown forever come June, has been release. It's called OpenHamClock. Looks pretty swish! openhamclock.com

I registered w8guy.radio yesterday. Nothing there yet but hopefully you'll be able to email [email protected] in the future! Or maybe I should go with [email protected]?

Found this nifty tool to create animated Mermaid diagrams. I've just messed with the free version but it's pretty cheap and even has a pay as you go if you just need a couple. It's at animerm.ai if you think it'd be useful.

Hey @pa-dev.bsky.social, I too am a Full Snack Developer!

Meet "Podbot," an AI chatbot @guy.dev built using Azure OpenAI to recommend podcasts based on your preferences. It uses Redis Memory Server to manage memory, so it remembers what you like across conversations. Build your own Podbot here (and feel free to open a PR): github.com/redis-develo...

"With elevated interiors, bold designs, and specialty drinks paired with your Taco Bell favorites, DRG’s venues are known as some of the most iconic destinations across the country." So you can get drunk and eat Taco Bell at the same time, I guess. Iconic. tacobellcantinas.com

Semantic routing improves predictability and efficiency in AI systems. RedisVL classifies user queries without LLM calls, reducing token usage and latency. Combined with LangGraph, it creates a deterministic flow for routing, execution, and decision logic. Read how here: medium.com/@bhavana0405...

I run a Discord server for my radio club. We have the following rules: 1️⃣ Don't be a jerk. 2️⃣ Don't do anything that makes us add a new rule. 3️⃣ If your not sure if rule 2 will be invoked, see rule 1. This work surprisingly well for our admittedly small scale.

"The legend lives on from the Chippewa on down of the big lake they called Gitche Gumee. The lake, it is said, never gives up her dead when the skies of November turn gloomy."

I like decentralized networks. In particular, I'm a fan of Reticulum. Reticulum is a fully-encrypted, anonymous, and decentralized mesh network that runs over all sorts of hardware—from Ethernet to LoRa radios to serial cables.

The Great State of Ohio has seen fit to pass a law requiring me to perform age verification on this platform. For the children or something. If I don't do this, I won't have access to DMs. I know how to VPN, not a huge problem. But, it does means I won't check my DMs as much. So, email me instead.

Modern problems require…modern memes? At #Devnexus, @guy.dev showed how embeddings + vector databases unlock quirky use cases (like discovering your meme twin) while solving real-world challenges 🦾 Recap here ⤵️ devnexus.org/posts/modern... 🙌 Join us for more inspiring sessions at Devnexus 2026!

So, @dcdietrich.bsky.social will be delighted to know that I got a pair of DMR radios. Once I figure them all out, we’ll have to chat!

Every time I see the letters AI, I have to figure out if it's some dude named Albert, a steak sauce, or hype.

Always a great time chatting with @davidgiard.bsky.social—even on a Monday morning at 9am! I wasn't able to cover nearly as much about ham radio as I would have liked, but if anyone has questions, I'm happy to answer them.

Monday on #TechnologyAndFriends: Guy Royse (@guy.dev) on Ham Radios

Everybody's putting AI in their apps. They're stringing APIs together and sending the results down to the browser. But those APIs are expensive, the round trips are long, and there's a lot of data being exposed. Maybe there's a better way? www.youtube.com/watch?v=nBaG...

Vibe coding browser-based AI stuff. And asking the important questions.

Vector search is cool. Really cool. And, we're all itching a reason to use it. And there are some really good reasons. But there are some, well, not so good ones as well. Know the difference and don't let vector search become your latest Golden Hammer. www.youtube.com/watch?v=Ryme...

I watched a YouTuber react to The Rocky Horror Picture Show last night and now all the songs are stuck in my head.

RAG !== vectors. The R is for retrieval—i.e. get useful stuff. You can do that lots of ways: 📄 Full-text search 🧾 SQL query ⚡ @redis.io key lookup 🧠 Yes, even vector search It's not how you retrieve—it's what you retrieve. Get the right data. Feed it to your #LLM. That’s the magic of #RAG.

Whenever things get broken and absurd, the circus music starts playing in my head. I sometimes say “Circus Music Intensifies”. From now on, I think I’m gone use the emoji combo of 🤡🎶📈.
