My name is Rafael Martinez Guerrero and I am currently working as a Chief Engineer at the IT Department (Formerly Center for Information Technology / USIT) at the University of Oslo. Over the past years, I have been a member of the Division for IT Infrastructure, focusing on system monitoring, data collection/analytics, automation and trending.

I got my first computer in the 1980s, an Amstrad CPC 6128 with a Z80 processor and 128Kb of RAM, running CP/M Plus and AMSDOS. Since then, I have used and tried various systems and vendors, but my primary operative system for the past 28 years has always been Linux.

I am specialized in Linux system administration, PostgreSQL database administration, monitoring and capacity planning, automation, performance tuning, security hardening, high availability and disaster recovery.

About Emc2Net

Emc2Net is my homepage where I have consolidated some of the projects, articles and presentations I had scattered across the Internet since the 1990s. All future articles and projects will also be published on this website.

For a long time, I was tired with maintaining different frameworks, modules and technologies for these simple pages, not to mention all the security problems I had to deal with when running dynamic pages. So, in early 2022, I moved Emc2Net from a Drupal/PHP/PostgreSQL system to a simpler solution using HuGo, an open-source static site generator. The theme used in Emc2Net is based on the Researcher theme. You can visit the old version of Emc2Net in the “Internet Archive”.

If there is one thing I have learned over the years is to keep things as simple as possible to try to avoid problems and over complicated, unstable and unsecure systems.
