I started using GitHub Actions to handle the Hugo build and deployment of this website. I was using a dedicated AWS IAM user with the required policies and added their Access Key ID and Secret Access Key as repository secrets.

I sat my HashiCorp Certified: Terraform Associate exam yesterday. I had been using Terraform over the last year, looking at ways of improving the speed and quality of the infrastructure builds on my last contract.

AIX Levels are named based on Release, Technology Level, Service Pack, and Build Sequence Identifier e.g. 7100-05-04-1914. As well as the current OS level, the oslevel command can show details of the TLs and SPs on a server along with details of any up- or down-level filesets.

I have been working with IBM AIX for almost 28 years, starting with v3.2.5. Over the years I have considered taking the various certification exams that IBM used to offer but never got around to organising it.

The final part of my marathon training block was the 2-day Oxygen Technician and Gas Blenders course. This started in the classroom, discussing Oxygen handling techniques and enriched breathing mixture (more commonly known as Nitrox or EANx).

There was no rest as I was straight into the Cylinder Testing Part 2 course, the first part of this having been covered in the DITC.

It was time to start putting everything we learnt during the course together. We each worked through a scenario where we were performing a Periodic Inspection and Test (PIAT) on an old aluminium cylinder.
