Once upon a time, I tried to be a rock star, and that didn't work out, so I pursued a career in a secondary passion... IT. That pretty much worked out, and I'm now comfortable.
Music remains my primary passion, though. I'm not particularly good at it, but I find the acts of creating arrangements, writing lyrics, and engineering mixes therapeutic and quite satisfying.
So although I remain pretty frugal with it (it is just a hobby at this point, after all), the occasional piece of "gear": a new audio interface, midi controller, VST, instrument, sample bank, etc... is rewarding and helps to keep me sane and happy.
IBM reboots iconic mainframe: Encrypt data all the time, at any scale
FWIW... I know it's not exactly what you're looking for, but IBM does host a Master the Mainframe contest each year. It provides free access to current z/OS systems for a while (few months, I think) and a project consisting of a series of challenges that guide you though learning the environment. IIRC... you must be an enrolled student to actually win the prizes, but anyone can sign up and perform the activities. One of the mods on /r/mainframe helps coordinate the contest if you're interested in learning more about it.
