When I started this blog, I did the laziest possible thing: pushed the source to a public GitHub repo, flipped the GitHub Pages switch, pointed blog.diego.dev at d6o.github.io , and forgot about it. It worked. I wrote five posts. I moved on. 
 Last week I came back to write something new, looked at the browser tab, and realized two things at once. First, I wanted my agents to be able to do…
I first heard about Cloudflare around 2011, on Google Reader. 
 I was 18 or 19, working at a small shop where most of what we shipped ran on an internal PHP framework that was mostly chunks of Zend Framework copy-pasted into custom code, with a lot of jQuery on top.

Building and Evolving My Personal Server: From Naive Trading Bots to a Streamlined Docker Setup with Caddy 
 Back in 2017, I embarked on an exciting (and somewhat naive) adventure when I created my first personal server (a

Reviving My Mom’s Love for Retro Gaming with Lakka and a Raspberry Pi 5

Although I had seen this was possible before, I had never really looked into it—until now. I embarked on a journey to
set this up, and while it wasn’t completely smooth sailing, I eventually got it working. Here’s how it went. 
 Finding the Right Sync…
The internet has been a central part of my life for as long as I can remember. It all started in the early 2000s when my
parents bought our first family computer. Back then, internet access was limited, and I could only use it on Saturdays
after 2 pm because bandwidth was cheaper during off-peak hours. But those restrictions didn’t bother me; I was hooked on
exploring the digital…
In this post, we’ll walk through how to use Go to subscribe to new blocks on the Ethereum blockchain and print out the
transaction hashes for each block. This is a common task when working with Ethereum, especially for monitoring or
analytics purposes.
