I am currently in the process of setting up a mixed-architecture k3s environment. Primarily consisting of RHEL based distributions, with further virtualization in various regards. Completed with FC backed SSP, and (soon) tape archival. This environment currently runs Hercules-SDL, which with enough time, may eventually export MVS 3.8j instances publicly for others to learn. The intended goal is to create a learning environment where I benefit learning hosting, to those using. Each user will be given a 1GB RAM DASD disk to start out with, with allocated local storage for duplicative backups.

All of which slowly over time gets backed up to tape, so per-se in 10 years, you still have what you were learning. All in progress of course, a lot of hurdles!

I spend my time learning what makes the world work, from the enterprise workforce in the background processing every bit of information users generate daily, to the machines we interact with in person to achieve the things humanity now takes for granted. Most of my time has been allocated to electrical engineering, enterprise computing, legacy computing, years of hosting/managing services/game servers for others and myself, offering troubleshooting services/advice, vintage computing, vintage restoration, and some mechanical things like small engines/transmissions. Production work mainly revolved around game hosting, re-hosting services, troubleshooting customer installations/applications, while maintaining the actual production systems. The communities I've been given the privilege to administrate, moderate, or else-wise, vary in scale from small minor projects with friends to large communities, large marketplace communities.

~4 years of active production work,
~5 years of managing active communities of various scales,
~10 years of self teaching anything under the sun,
~300 hours of accredited courses.

For a full break down:
Flashing GPUs, Motherboards, various other chips.
CoffeeTime Modding LGA1151 with BGA/ES chips.
Physical Hardware modifications on various things, primarily GPUs.
Restoration of Vintage Systems, modern integrations of said devices in a lab environment.
Mining Cryptocurrencies (Before the main-stream explosion).
Content Moderation / Game Server Moderation.
Re-hosting, Hosting, Troubleshooting, Customer Support.
Mission Critical decision making, in production environments.
Mainframe Emulation and Interaction.
Maintain and run a functional/operational homelab hosting services over years, mostly comprised of POWER systems, using Red Hat Enterprise Linux as the infrastructure with AIX as a learning project / supporting element.
Hyper-converged Infrastructure, Advanced Virtualization, Mainframe Emulation, Clustered Virtualization.
Server hosting for myself (of course!), creating my own communities (of course!), and ultimately, trying everything I can to gain experience where it mattered.
Disaster recovery for a small customer base coupled with disaster recovery from a hostile former employee, who had full credential access down to the databases.
Consultation in regards to expansion, and minimization of cost.
Small engine repair, dirtbike restoration, transmission rebuilds.

In the future I intend to get in to custom PCBs, which I'm already dabbling with, creating educational content on my own blog (soon) going over everything above, getting the certifications required for enterprise work with the machines I use in my homelab (POWER). Currently I am in the process of learning the intricacies of Red Hat and furthering my own understanding of the Enterprise world, after using Red Hat & Linux itself for multiple years on my own systems. I wouldn't have chosen to spend my time anywhere else, most of my time was allocated to learning, though life requires distractions sometimes.

It is very unlikely to be on my 'friends' list, feel free to try though.
No, I do not, and will not, have personal profiles on social media.
Yes, I do offer help to anyone who asks if the problem interests me.
