Hey everyone! In this post I’m gonna walk you through the process of installing Official Linux Nvidia Drivers for the RTX 50 series graphic cards on Debian 13 (Trixie). Some issues I found and other scenarios to consider such as OS upgrades. Something I love when using GNU/Linux is that there are multiple ways to solve a problem. And sometimes it will depend on the hardware you are using,…
Hey everyone! In this post I’m going to share my experience of USB booting the Raspberry Pi 3 Model B from an SSD. Although it is something I did almost one year ago, I wanted to share it… sorry for the 1 year delay xD! Probably there might be something I missed on my solution, so any feedback is really appreciated! Before the pandemic started, a friend of mine sold me 4 Raspberry Pi…
Introducing AWS Nuke! In this post I will give you a quick introduction to AWS Nuke , a tool developed in Golang that aims to delete all resources in an AWS account. This tool helped me a lot. Use Cases Cleaning Free Tier AWS Account This was a personal use-case, I created a free tier AWS Account some months ago and I’ve been using it for different purposes, some of the resources I created…
In this post, I will present a solution (one I personally find quite tidy) to a problem I encountered with AWS SSO and the Serverless Framework. Serverless Framework is one of my favorite tools when I need to work with AWS Lambda and other serverless services, it is an alternative to AWS SAM , but personally, I prefer Serverless Framework due to its support for various cloud providers and plugins.…
Some time ago I was working on creating a local docker-based development environment for some microservices at work so developers can have the necessary infra components on their machines and that will help them with their daily tasks. Initially, the business logic of some microservices were a black box to me. After containerizing the applications and creating the docker-compose setup, some of…
It is possible when you are writing code, at some point you might need to pause the execution of a process by calling the sleep(NUMBER_OF_SECONDS) function depending on the problem you are solving. In this post, I will share what I learned so far while investigating the internal kernel mechanisms that make the sleep function work the way it does. I appreciate your feedback. I am not an expert on…
Hello, during the months of October and November different social and political conflicts occurred in Bolivia, this entry is not so much to discuss the political issue, it will be a 100% technical entry but it is related to those events. The previous week a large number of clients from a local ISP received an SMS with a link bit.ly to an MP4 video in Dropbox that was later deleted.
Hi, some time ago I posted about my initial setup in my Debian personal machines that use for work or personal projects. Some of the things I setup are: applications, desktop look and feel, etc. The last months I installed and re-installed my Debian machines so many times in different computers that I use (new computers, new hard drives, etc.) and this taks was repetitive. Basically what I was…
The other day when I went out eating with my friend Francisco, he commented me about a personal project and what he wanted to accomplish. Listening to his questions the first tool that came to my mind that would solve some of the challenges he has was OpenSSH. What is SSH? SSH is a short for Secure Shell, it’s a protocol to manage services inside a network using a secure channel. One of the…
Hey,during my free time I was working a side project called Gocho . This application allows the user to share files in a local network e.g. home network, work, etc. with the difference that it will auto-discover other nodes. In this post I will explain what this application is all about, why I wrote it and some challenges that came up duting the development. Why I wrote this app? First I wanted to…

Operating System: GNU/Linux - Debian Stretch Dektop Manager: xfce4 Frequently Used Applications This is the list of application I frequently use and try to have them installed after I have a fresh computer.

Hey there, I am Sergio Guillen publishing via Github pages 😄. This blog is a project I will take again and publish content different from my previous blog which was mostly about Microsoft technologies. Since I stopped using those technologies —that I still get impressed with them e.g. C#— I had the good luck to meet new technologies, so I want to share some experiences I had with them or…
