DIY Sysadmin

This image has been generated by AI. Actually it’s several images that I merged together. I don’t have access to Photoshop anymore and I had to use GIMP. And, actually, it was not as bad as it was 10 years ago when I tried it last. I would prefer Photoshop but beggars can’t be choosers, so GIMP it is. But hey, it’s free at least. Also, with the uncertainty about the copyright of the AI generated work, I put enough (I think) work to make this image transformative. So, © 2025 DIY Sysadmin. All Rights Reserved.
