Ah, the usual "contact your system programmer" error. Fun.

If you are a student, or know one, it's not too late to register for the IBM zStudent Contest!

https://ibm.biz/studentcontest2022

Learn more about #mainframe, z/OS, JCL, Python, REXX and interact with it using modern toolings.

Contest is for students from accredited academic institutions, but challenges will be released on IBM Z Xplore afterwards.

Some time ago, I found that IBM Redbooks maintained a dictionary of mainframe jargon that mainframers used.

After learning about the number of acronyms on the #mainframe, I certainly wished I had found that earlier. And, from what I can see, not many people know that the dictionary existed too.

In any case, I gathered a collection of resources that may help you learn more about mainframes. Check it out at https://securitypuppy.com/links.

Finally got a chance to self-host a GoToSocial instance! Everything looks good so far. So, hello world?
