Sun, 13 Apr 2025 00:00:00 +0200

This spring clean-up focused on migrating Git projects from gitlab.com/ix.ai to a more structured and intentional home at gitlab.com/egos-tech. Along the way, CI pipelines were modernized, legacy configurations replaced, and everything was streamlined using shared Docker images and centralized Renovate Bot settings. The result: faster, cleaner builds and a foundation that’s easier to maintain—and maybe even collaborate on.

Thoughts on DevOps - Bottlenecks

Wed, 16 Jan 2019 22:00:00 +0000

Years ago, there was a worldwide tendency to adopt ITIL in the IT departments of all organizations, big or small. This, together with the wide adoption (although misunderstood by most) adoption of COBIT led to big and small companies setting up clear pillars, where the focus was on the activity being done, instead of the product or service delivered to the customer.

Website Provisioning – Automate Apache with SaltStack

Thu, 26 May 2016 12:21:06 +0000

Ever since I’ve started hosting my own domains, I’ve searched for ways to automate the website provisioning.

Android Debugging

WARNING: This documentation is outdated and will not be refreshed!

I intended to do this for a long time now, since Android Debugging goes hand in hand with Linux debugging. I’ve noticed, during my trolling on the >InsertCoin forum, that people that start messing around with their Android mobile (read: start rooting it), don’t know what to do if something fails.
