Video: How I Became a 10x Dev Using AI Agents, GitHub Copilot & Gemini | xylem | Gordon Beeming I recently spoke at the SSW Brisbane User Group about shifting from writing code to orchestrating AI agents. Here is the recording and a breakdown of the specific tools, workflows, and security sandbo...

Stop typing, start orchestrating. 🚀

I recently shared my workflow for using Gemini, Copilot, and a custom Docker sandbox to ship faster (and safer). It's about managing agents, not just writing syntax.

Upgrading My Wife's Portfolio to TinaCMS with the GitHub Copilot CLI | xylem | Gordon Beeming A task estimated to take 5 hours was to convert my wife's portfolio to use TinaCMS. I decided to see if the new GitHub Copilot CLI could do it for me. The result was surprising.

I pitted the new GitHub Copilot CLI 🤖 against a full website migration to TinaCMS 🦙.

One prompt handled the entire task, installs, refactoring, and even generating docs 🤯

My AI-Powered Workflow: Building a Full-Stack App with ChatGPT and GitHub Copilot | xylem | Gordon Beeming What if you could build a complete application without writing most of the code? I put that to the test by building a URL shortener where I acted as the architect, ChatGPT as the project manager, and ...

I built a full-stack URL shortener by letting AI do the heavy lifting. 🤯

ChatGPT created the plan
GitHub Copilot wrote the code
My role? Architect & reviewer

I wrote a blog post about the entire workflow.

The Conprism: The Illusion of Precision in Estimates and Star Ratings | xylem | Gordon Beeming It started with a typo and a thought about 10-point rating scales. I realized our quest for precision in work estimates and user ratings often creates a "conprism", a false sense of accuracy. Here's w...

What's the real difference between a 7/10 and an 8/10 rating? It's an illusion of precision, and the same thing happens with software estimates. My thoughts on the 'conprism'.

The Double-Edged Sword of Conveniently Named Exceptions | xylem | Gordon Beeming Choosing a C# exception because its name sounds right is a common anti-pattern. Learn why this leads to confusing logs, unnecessary costs, and better ways to handle errors.

Ever chased a NotSupportedException down a rabbit hole, only to find it was a business rule? 😅

This anti-pattern of "conveniently named exceptions" can waste hours and hide real production bugs in your logs. 👇

Language learning isn't all about sharing progress, it's also about sharing the things we use to help achieve our goal. I hope to foster a community of study session and resource sharing to help each other on each of our own journeys.

On the plus side, all that extra time is experience that will make things easier later 💪

Thanks for the feedback Greg 💪

I Let Copilot Refactor My App, So You Don't Have To (The Wrong Way) | xylem | Gordon Beeming I had a seemingly simple refactoring task on a sample project and I thought, "Let's get GitHub Copilot to do the heavy lifting!". What followed was a spiral into chaos that taught me a crucial lesson ...

I let Copilot refactor my app the wrong way so you don't have to. It completely messed up my EF Core migrations. 😵‍💫

My new post details the botched attempt and the right way to do it with a hybrid IDE + AI approach.

Redesigning My Blog with an AI-Powered Workflow | xylem | Gordon Beeming My blog needed a facelift. Instead of weeks of manual CSS changes, I used Gemini for planning and GitHub Copilot for execution to completely redesign my site. Here's how the AI-assisted process worked...

I recently went through a full redesign, but not in the traditional way.

My workflow:
🧠 Gemini as the Tech Lead
💻 GitHub Copilot as the dev to do the heavy lifting.

Is your EF Core query with multiple `.Include()`s causing a Cartesian Explosion and running for 30s+? 🐌

We fixed ours with a one-line change: `.AsSplitQuery()`. It's a lifesaver for rich domain models.

New Alternatives to Windows 11 Explorer - Files and File Pilot! YouTube video by Scott Hanselman

Learned about File Pilot (filepilot.tech) from @scott.hanselman.com's video this morning.

It's so fast and snappy that it makes me want to cry.

Why can't anyone write software like this anymore?

I’ve been using warp and it’s more friendly as well, I’ve not tried ghosty though

I have been thinking about getting an arm windows device as a secondary machine to run windows and Linux on it for certain tasks where it’s the right OS

Need is a short list (probably similar to windows day, want/like is slightly longer as I find with mac feeling much faster than my windows machines (I definitely didn’t run the equivalent spec machine) I find that the machine finishes tasks fast enough that I’m always looking for tools to go faster
