Mainframes power the enterprise.
But do you know who ensures they stay secure, optimized, and ready for modernization?

We’ve published an executive guide on the strategic role of the z/OS system programmer.

Inside:
• responsibilities
• performance management

I just published the January report for open source software packages for Linux on #IBMZ and #LinuxONE 🐧

The team tested nearly two dozen projects, including doxygen, elastic Logstash, and PHP.

Elsewhere in the open source world, Apache Tika and WeKan began releasing s390x containers, and libdfp was on-boarded to our GitHub Actions service 🎉

Okay Fedi, momma needs some #electronics help

I am restoring an IBM 3279 color mainframe terminal for what will be the greatest prank I'm the history of IBM teleconferencing. But the on board battery is dead like Tupac and the Real Paul McCartney. Is there some way for me to make an appropriate replacement at home using AAs and a breadboard?
