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...

La Gran Estafa por John Grisham


Este libro lo vi en el facebook de la librería y me llamo mucho la atención, pensé por un momento que trataba de estafas de casino, o robos de bóvedas o algo a lo que Hollywood nos tiene acostumbrado (Ocean 11 o The Italian Job). Estaba equivocado, no tiene nada que ver con esto. Narra la historia de 4 companeros de la universidad: Mark, Todd, Zola y Gordy, como estan estudiando derecho en una universidad de bajo renombre, y se están dando cuenta que van a concluir sus estudios y no se sienten preparados. Entre los cuatros tienen casi 1 millón de dolares americanos en deuda. Provocando que uno de ellos decida saber como se dejo tentar por ese mundo perfecto de obtener un préstamo y después iba a tener un excelente trabajo. Es cuando descubre que a pesar de no ser ilegal, es un engaño total, ya que estaban en una fabrica de hacer titulos universitarios y no garantizan, absolutamente nada. Solo que tenían que pagar la deuda. 

Se los recomiendo, mas si desean una recomendación para volver a leer un libro.

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 ...

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...

How I miss you Synaptic!

Several years  have passed since we saw the Synaptic included in Ubuntu. You can found reasons here  . So in a clear english the reason was to have a better add/remove program for users. A friendly application. The explanation sounds good, I didn't complain about that, until right now. Ubuntu has change a lot, it's really a friendly user OS. I have use CLI when necessary, but today I couldn't believe it. I'm a Google Chrome user, I know you will tell me it's not open source or I should use Chromium or FF. But no. I'm a user of Google Chrome, and many people also prefer Chrome over Chromium, so why it should be quite complex remove it? If Ubuntu wants to be more friendly user why you should use the terminal for removing one of the most popular web browsers? I could understand if is a browser few people use, a good reason. But not a popular browser, Chrome is one of the most popular browsers on the world! A screen shot of the Ubuntu Software Center, trying t...
