Tech - Red Hat Enterprise Linux 7 to 8 - CPU Unsupported Inhibitor

I've been doing quite a lot of upgrading and migrating RHEL 7 machines to RHEL 8 or 9. Since RHEL 7 is out of support in June it might be time to start thinking of migrating. Using LEAPP this is really simple but a quick one that I

Tech - ESXi to Proxmox the real migration

Let's cut around the fat here... the Broadcom takeover of VMware has had a huge impact. For some businesses, it's not cost-effective to keep a VMware environment anymore... This has been on the Geekden cards for a long time..... well before the entire Broadcom acquisition. <

Tech - Setup Autopilot VM

So I've been doing a lot at the moment with Intune and Autopilot. Normally I can get hold of a laptop to add to Intune but I needed a faster way to revert changes and then retest. Using Proxmox before I start the install process I've

Code - Organise Photos Using EXIF Data

So, ok this is a little bit of a OCD post... Throughout the year, we take thousands of photos and store them on Geekden's NAS. But finding the image later can be a bit of chllange. The issue is they normally look like this: But using a bit

Music - Underrated Albums V1

I've been doing quite a lot of traveling lately and it's re-sparked some old playlists I've not heard for a while. I've got to say even if you've never heard of some of these albums before then I'd

Tech - So, Bye Bye ESXI?

So a bit of a clickbait title I know... So as I'm sure unless you've been living under a rock, VMware has been bought out by Broadcom. This has created a panic over the pricing increases moving from a perpetual to a subscribing-based pricing model. But

Travel - Swiss Railway Clocks

I will sound a bit like Sheldon Cooper here but my Asperger's brain sometimes spots something strange. Something that a "normal" person wouldn't gloss over or look at. See when you travel in Switzerland even if you do happen to drive you 9/10

Cars - Fuel Delivery - Diesel Starting issues

Okay, this one once had me stranded. It could be a pointer or preventive maintenance! Typical for European cars fuel is delivered from plastic fuel lines, in my case this is no exception. But as this might be an easy cost-saving option, it can lead to air entering the system.
