  1. libzpc - A Protected-Key Cryptographic Library
    ibm.com/docs/en/linux-on-syste

    There is one enhancement in the libzpc 1.5 version:
    libzpc 1.5 now reacts to a verification pattern mismatch caused by live guest relocation or migration by re-creating the protected keys from the key material it was derived from.

  2. 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.

  3. 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 🎉

  9. 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?

  10. 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.

    AI [probably referring to a LLM] is not trained by professionals or a single end user, because it requires such huge amounts of input training data...

    You are correct and you are incorrect.

    From scratch finding data for pattern matching is tough and requires high performance engines, trade-offs, and money. But we stand on the backs of giants.

    There are trained ethical LLMs, certified to be so and deep pockets to back the assertion and the necessary curation. They are not necessarily free. From those seeds AIs can be built to do the things of which I speak.

    If IBM can do it (and they do; having gone to the training and hard sell, I know), Apple Intelligence could be built and use Apple engines as infrastructure. Big Blue's giant Z mainframes, which are blades in pretty artwork boxed server racks, are performant due to their custom chips, virtual system management, tuned I/O structure, and multitasking software. Apple chips are performant, custom, and cheaper for the end user. Apple Intelligence is likely Apple's WatsonX App-Killer that'll make the difference, and most certainly runs on Apple hardware increasingly running on renewables.

    My point isn't so much building LLMs from scratch, but applications built on a platform and then trained from private user data and via user curation. If I implied otherwise, I wasn't clear. Sorry.

    I assume Apple's LLMs are ethical. I also assume that Apple is exposing AI APIs for use by developers.

  48. I just stumbled over a thread that there would not be enough engagement for Linux documentation.
    For #LinuxonZ #ibm is constantly publishing updated technical documentation.

    Here just 2 publications hot of the press :

    -- Device Drivers Features, and Commands for #Linux #kernel 6.10

    ibm.com/docs/en/linux-on-syste

    and
    -- Managing #Crypto Express adapters with a Trusted Key Entry workstation for #CCA and #EP11 applications.
