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
• compliance
• hybrid integration

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 🎉

Here we are, the last report of the year from the #Linux on #IBMZ and #LinuxONE porting team and beyond 🚀
The list for November is an impressive one with nearly three dozen projects tested, including Apache Cassandra, fluentd, and neo4j
We also confirmed that the GnuCOBOL project has been on-boarded with our GitHub Actions service for s390x 🧑💻
The #s390x open source software team at IBM confirms the latest versions of various software packages run well on #Linux on #IBMZ & #LinuxONE 🐧
In October 2025 validation was maintained for two dozen projects, including #ApacheActiveMQ #InfluxDB & #Rails 🎉
We also on-boarded libdfp & qsv to our new hosted GitHub Actions runners, and saw Rarr add CI and VictoriaTraces begin releasing binaries 🎁

The Dev team neighboring my Org is looking for an OpenShift Hypervisor Developer. If you want to become a key member of a dynamic team, you will play a vital role in designing, developing and integrating new Core Virtualization features directly into Layered Products such as OpenShift Virtualization (KubeVirt and Kubernetes).

Hear the latest about IBM Z and LinuxONE, and join over 250 industry expert speakers and global thought leaders who will highlight industry trends and innovation spanning AI, Hybrid Cloud, Quantum-Safe Security, and more!
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?
libzpc - A Protected-Key Cryptographic Library 1.3 + 1.4:
libzpc version 1.3 introduces a new protected key origin called ultravisor retrievable secret. You can use protected keys derived from retrievable secrets for encryption and decryption (AES), and for sign and verify operations (ECC) on an IBM z17.
libzpc version 1.4 supports new types of protected keys from origin retrievable secrets:
full-XTS and HMAC protected keys. New groups of function APIs are provided to run on an IBM z17
to perform operations with these new key types.

There are growing challenges in managing cryptographic assets while preparing for the emerging risks of quantum computing.
Pradeep, Parameshwaran, STSM , Chief Architect , #Security and Compliance on #IBMZ and #LinuxONE will talk on how we can provide a centralized approach to discovering, classifying, and managing cryptographic keys and #certificates across applications and systems, ensuring visibility and #compliance. This session will focus on partner point of view on #Quantum Safe #cryptography , followed by details on IBM Quatum Safe Explorer product and #IBM zCDI product.
