@aka_pugs code written from that era is still up and running on today's mainframes in the banking sector.

Happy Friday!

Last week I published a #CircleCI tutorial where I tested a Go application on an x86 container and an #s390x VM with the machine runner: https://community.ibm.com/community/user/ibmz-and-linuxone/blogs/elizabeth-k-joseph1/2023/08/01/circleci-self-hosted-runner-for-linuxone-tutorial

Then I had a bit of fun and added my Raspberry Pi 4 into the mix for ARM 😁 :raspberry_pi:

@opensuse Once the #oSC23 recordings are available, I'll watch Sarah Julia Kriesch talking about the #s390x port of @opensuse:

Not that I have a #mainframe at home, but I love working on an learning about non-x86 architectures.

Tuesday, April 4th, my friends! Big day!

Register to watch live at 10AM US Eastern time as #IBM unveils news about #IBMz16 technology: https://ibm.biz/BdPpjk 😍

I've really been geeking out internally over this, so if you're the least bit curious about #s390x tech, I highly suggest checking it out.

Nice to see an article like this that I didn't write 😅

"Open Source? WHY NOT s390x in your efforts? Part 1." https://jerrysaulman.medium.com/open-source-why-not-s390x-in-your-efforts-part-1-e54474036ddc #s390x #IBMzSystems #LinuxONE #OpenSource

Here's the big reveal: Installing machine runners on #s390x uses the same documentation as all other architectures. There's no magic here. 🚫🪄

I even used a free #CircleCI account and a free account from the #IBM #LinuxONE Community Cloud (https://developer.ibm.com/articles/get-started-with-ibm-linuxone)

But the runner-test is very boring, it's just to confirm that everything is connected and the result is just an echo statement. I'm not testing my code.

Check out the #CircleCI docs here: https://circleci.com/docs/runner-installation-linux/ #s390x #LinuxONE #zSystems

It's straight-forward to get a basic test with included images going on #CircleCI, unimaginatively called "build" in my screenshot below.

Machine runners? More involved, but now that it's available for #s390x I wanted to try, and there we are with a successful runner-test! 👇 #LinuxONE #zSystems

"Among the architectures now supported by Mold include DEC Alpha, 32-bit Arm, AArch64, 32-bit x86, m68k, PowerPC 32-bit, PowerPC 64-bit, RISC-V, s390x, SH-4, SPARC 64-bit, and x86_64." 😍 https://www.phoronix.com/news/Mold-1.9-Released

Working with them now to get them set up with a permanent #s390x VM so they can continue the support they added in October 2022 #Mold #linker #s390x

I got a nice New Year surprise, @ubuntu 22.04 is now available on the #IBM #LinuxONE Community Cloud!

What's that, you ask? It's a mainframe hosted at #Marist College that has free virtual machines available for developers, hobbyists, students and others looking to test out their software on the #s390x (IBM #zSystems & LinuxONE) hardware architecture: https://developer.ibm.com/articles/get-started-with-ibm-linuxone/

The #s390x open source team at #IBM for #LinuxONE works to get the latest versions of open source software running for #Linux on IBM #zSystems

In December 2022 currency was maintained for over 30 projects including #Apache Ignite #WildFlyAS @grafana & #Ruby

"if an LPAR is configured like this, a default Ubuntu (20.04 or newer) installation will automatically perform a secure boot installation and no further tasks are required"

#procps 4.0.2 failed it's tests on the #s390x architecture.

The failed test simply got the pid using the library and resident memory size and checked for non-zero. Digging deeper the memory was zero but even the new ps that uses the library says it's not.

The test mistakenly uses u_int not ul_int. Passed on the amd64 but not s390x!

#opensource

Good morning, today I'm working on a @debian #Science Team issue: the 'getfem' package, providing an open-source finite element #FEM library, is failing to build on the #s390x architecture. I haven't dealt with this package before but it's causing an issue elsewhere.

In particular it's tests that are failing, which is pretty common to see for this type of software, almost always due to differences in numerical approximation between architectures.

The Open Build Service has seen a big increases in build power for #s390x since August thanks to #IBM and #SUSE providing a #LinuxONE machine. #ThankYou
