Site Update August 2026
by Jan Holbo RasmussenSite update as of August 2026
This site has long been in a state of missing new posts. But here’s to a new lease!
It actually comes not just as a refresh, but a whole new base, as we have changed from Wordpress as a CRM to an Open Source Static site generator called HUGO. This shift should make the site delivery a lot faster, as the pages are actually pre-generated abd just needs to be served straight from the server.

About J-Cave

This site is my playground where I will share some of my interests and learnings (is that a word?) It will eventually be quite diverse, including topics like Retro Gaming and Retro Computing, Homelab, Website building, Programming, Books, Storage, Networking, Microsoft 365 and Sys Admin, LLMs, etc.

Ads?
This site is done on my own time, and none of the content is behind a paywll. In order to - some time in the future - subsidise the costs of running this site; hosting, materials, etc, I have decided to include ads from Google Adsense. This is far from a gold mine - admittedly this site is far from being slashdotted, visits are few, and so is ad income - but perhaps some time in the future, I will be able to pay at least parts of the costs of running such a site.

Back from hiatus 2022
by Jan Holbo Rasmussen… and 100 Days of Homelab!
Huge apologies for this past years hiatus. I have not posted in more than a year. Actually my latest post was April 24th 2021. But now I am back!!!
A lot has happened since my last post. First of all I started a new job on October 1st as an IT Technician, working at a small IT company. We do IT support for small businesses and private individuals. We are mainly a Microsoft shop, but I do get to do a few other things from time to time.
