When “Pre-Installed OpenWrt” Isn’t Plug-and-Play

  Lessons Learned After Finally Configuring a Raspberry Pi CM4 Mini Router (Bought in 2022) Product Mini Router built with Raspberry Pi Compute Module 4 Dual Gigabit Ethernet NICs 4GB RAM / 32GB eMMC Pre-installed OpenWrt Compact form factor, fanless, low power Background: A Device That Waited Its Turn I bought this device back in 2022 . At the time, it looked like the perfect small router: Raspberry Pi Compute Module 4 Dual Ethernet ports OpenWrt already installed No SD card required thanks to eMMC But like many homelab projects, it ended up sitting on a shelf . Fast forward to today — with more networking experience, a clearer home network plan, and a real need for a flexible router — I finally decided to configure it properly. That’s when the real journey started. What I Expected (Even in 2025) Even knowing this wasn’t a consumer router, I still expected: Plug WAN into my upstream router Plug LAN into my laptop Access 192.168.1.1 Hav...

Scratch for Arduino

Whoa it sounds cool. Everyone knows what Scratch is. The programming language for kids, and almost has an idea what arduino is.But this two names together? It's not possible. Yes is possible, many people complain that is difficult to program in arduino. They will like something simple as the Lego Programming.

I was reading yesterday, and discover this: S4A
Scratch for Arduino. I haven't try it yet, but I am waiting to get home tonight to test it.
I will do some of the tutorials and write about it, if you have test waiting to read your opinion about it.

Understanding Liveness, Readiness and Startup Probes in Kubernetes

 This is a small article about understanding the liveness, readiness and startup in kubernetes.  There's good explanation in the kubernetes documentation: https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/ This video also explains well the process: https://www.youtube.com/watch?v=aTlQBofihJQ But I wanted to understand it in a practical way. So I have this demo: https://github.com/DiegoTc/guest-book-js-docker/tree/Running-App-Version-1 It's a simple application running on a kubernetes cluster. https://github.com/DiegoTc/guest-book-js-docker/blob/Running-App-Version-1/argo/deployment.yaml apiVersion: apps/v1 kind: Deployment metadata: name: chat-ui spec: replicas: 1 revisionHistoryLimit: 3 selector: matchLabels: app: chat-ui template: metadata: labels: app: chat-ui spec: containers: - image: diegotc/guestbook:20230803-064434 imagePullPolicy: Alwa...

Modern Architecture for Native Apps with AWS Backend: A Practical Guide

Introduction Designing a mobile app today goes far beyond building a beautiful interface. Native apps — whether for iOS or Android — need secure authentication, user role management, real-time communication with the backend, and scalable infrastructure to support growth. In this post, I’ll walk you through a clean and modern architecture to connect native mobile apps to a robust backend on AWS. The architecture is modular, scalable, and aligned with best practices for security and performance — without relying on overly complex tools. Why it matters: apps today are more than just UI A production-grade mobile app often includes: User login (email, Google, or others), Differentiated access for multiple roles (e.g., user vs admin), Secure token-based communication, A backend capable of handling business logic and data, Data storage, asset management, and scalable APIs, Compliance with Google Play and App Store requirements. All of these require a backend architecture ...

Getting Docker Syntax In Gedit

I have been working with docker in the last days, and encounter the syntax issue with gedit. Just pure plain text. So make a small search and found an easy way for fixing this. I found Jasper J.F. van den Bosch repository in GitHub and found the solution for this simple problem. We need to download the docker.lang file, available here:  https://github.com/ilogue/docker.lang/blob/master/docker.lang After that, you go to the folder you save the file and do the following command. sudo mv docker.lang /usr/share/gtksourceview-3.0/language-specs/  If this doesn't work you can try the following: sudo mv docker.lang  ~/.local/share/gtksourceview-3.0/language-specs/ And that's all!
