About the Content
© 2015-2025 by César Andrés Arcila Buitrago
Compendium of content from the blog “Techie Universe by César Andrés” (which may eventually be available at onmind.net, depending on access), with material that I have been developing since 2015 based on my assimilation of knowledge and notes, with categories such as Code (Programming Languages), DevOps, Cloud (AWS, etc.) and more topics in Software Technologies and Architecture, including my own technologies (ABCode Programming Language, OnMind Method, OnMind-XDB, OnMind-PUB, etc.).
Over the years, it has taken shape as a technical documentation center and starting point for a knowledge base around the OnMind project and general consulting in the field of computer science. In this way, you will find organized topics related to the system, guides and tutorials, articles of interest, many technical, including software architecture, and key notes from my experience.
To create it (either in blog or book form), I use the Markdown convention as a source and generate the website (blog) with my project OnMind-PUB.
