30 years in IT. Still curious.
I have spent 30 years connecting systems. Some of them still hold a grudge. Architecture, integration and security pay the bills; Linux, writing and photography keep the human part operational.
Four ways to put this human to work. My articles are in Czech.
Diplomacy for systems that refuse to speak. — architecture / integration / security
APIs, EDI and SAP. I work on the parts that have to agree with each other — including the people who use them. A diagram is a useful start; the interesting questions live in its connections.
Diagnostic question: What happens between the boxes in a diagram?
From my desk: diagrams.net, a tool for making connections visible
Linux at home. Windows of opportunity elsewhere. — Linux / open source / Gravister
Linux at home since 2004. Testing, documentation and Czech translations are part of how I contribute. Now I am building Gravister: tools for composing pages, shaping presentation and creating derived themes in Grav 2.
Diagnostic question: Can you understand, maintain and change what you own?
From my desk: firmware and Linux, when updating is not a given
Instructions for my future confused self. — articles / practical guides / talks
I write in Czech about Linux, photography and practical technology. Understanding a tool is part of using it well. I enjoy finding an explanation that gives the reader something they can actually try.
Diagnostic question: What does the reader need to understand next?
From my desk: Yakuake, a terminal that appears when you need it
People with no pause button. — TeamGym / photography / perspective
I photograph TeamGym. Motion, light and timing create a different kind of technical problem — with a human moment at its centre. The photograph is where the preparation meets something you cannot ask to happen again.
Diagnostic question: Which moment is worth keeping?
A website should be something you can understand, maintain and make your own. That idea is taking shape as my product family for Grav 2 + Admin Next / Admin2.
Modularis — Page composition: arrange modular content into a page.
Thematis — Site and theme presentation: give the website its visual character.
Derivis — Derived-theme scaffolding: create a starting structure for a theme derived from an existing one.
These products are in development. This is an introduction to their purpose; public releases and source links will be added when available.
