"Slop" is the defining insult of this tech cycle. It’s a useful word, but should we use it to dismiss a whole new category of art without consideration?
History says no. Every major technological shift in art triggers the same reaction.

Why is it that when you start a task with a coding agent everything seems to go well, but then suddenly it spirals into slop territory producing horrible code?

I'm thinking about creating a new podcast (for the lack of a better word) called "Go Live Fridays". The goal is to do a 40 min to 1 hour conversation with one developer about the things they care about and, hopefully, are not going live with them on a Friday! (see what I did there?)

I've been wanting to play with YouTube for a while. To start, I recorded this small video showcasing my workshop at GopherCon LATAM 2026 that happened a couple of weeks ago. It is short but hopefully it captures all the fun we had building games with Go, Gemini and Antigravity!

Mensagem clara hoje na GopherCon LATAM 2026: o importante hoje não é mais escrever código, mas saber ler código e identificar os problemas que a IA está introduzindo. IAs tem uma tendência a implementar soluções mais complexas do que necessário. O senso crítico humano é o diferencial.

If you want to build AI agents in Go, where do you actually start?
In Part 3 of "Gemini for Go Developers", I wanted to see how each option feels in practice. To test them, I built the same multi-tool agent across all three stacks 🧵👇

"I know kung fu." - actually, I don't. But my coding agent does!
Every time Antigravity loads a skill on demand, I immediately think about the classic scene in The Matrix where Neo has kung fu "installed" into his brain. 🧵👇

Writing a basic agent loop in Go takes 20 lines of code. Building a production agent takes a deliberate architecture.

[1/8] I believe this generation can master software engineering orders of magnitude faster with AI, but only if you use it the right way.
First, let's think about how people learned engineering before AI. For me, it all started with a single question: how do video games draw things on screen? 🧵

I just did a code review for a colleague, the old school way: yes, I actually read the code. And to aggravate, I didn't use AI assistance either.
I also put my pedantic hat on, because why not, right? lol... 🧵

Do you know what a game jam is?
Think of it like a hackathon, but for game development: a creative sprint where developers design, code, and build a playable game from scratch within a set timeframe. Sounds fun, right? 🧵👇

Whenever a new model lands, I have a ritual: revisit past projects and give them a full glow-up.
This weekend with Gemini Flash was pure hyperfocus across 5 codebases.
Near-zero wait times kept me in total flow. (Or it might be my ADHD, but I still blame Flash! ⚡) 🧵

Coding agents are great and all, but how do you fine-tune them for your tech stack?
In Part 2 of Gemini for Go Developers, I explore how I use open agentic standards like MCP and skills to fine tune Antigravity for Go development.

I hope you will appreciate the irony in this finding. I just found out there is an official MCP server for the Agent Skills Spec. This server enables agentic consumption of the spec to create skills... Then I realised: what about MCP? Do we have an MCP server for it? No! Wait for it...

The first session I'm attending at GopherCon UK. Bill Kennedy is showcasing kronk (www.kronkai.com), his Go library for LLMs. It worked seamlessly in my machine first try. Do yourself a favour and clone github.com/ardanlabs/kronk right now. Run "make example-question" and watch the magic happen!
