"This could definitely make for a fun weekend project to mess around with."

That's what @thomholwerda of @osnews wrote this week when he shared details of our latest IBM LinuxONE and Linux on IBM Z open source software report, and went on to highlight the IBM #LinuxONE Community Cloud!

Well, the weekend is coming up 😄 #mainframe

One of my favorite things about #mainframe hardware development is that it undergoes #earthquake tests.

It's been a while since we've seen new footage, but now we have a new video!

The IBM z17 that announced today undergoing tests under the condition of an 8.3 magnitude earthquake!

I had to dig up a specification for the new IBM z17 and voila, the Redbooks are live today too! They're basically my go-to for all this knowledge: redbooks.ibm.com/feature/z17

And I have my image-heavy blog post about some of my favorite hardware bits of this new #mainframe drafted up, which I hope to publish in a couple weeks.

A thread in a lot of the #IBMZDay Launch sessions is skills, which is nothing new for the #mainframe space 😉

But something that is new is clients speaking up about how helpful some of the AI-driven tooling has been in helping get newcomers up to speed. From making documentation easier to find and search, to gaining a firm understanding of data & code architecture. Cool.

But we are still working on traditional training and skills too with the Mainframe Skills Depo! ibm.com/z/resources/mainframe-

Tracing back #programming language history to the root of the very first (mnemonic) #GOTO instruction (jump/branch) I found two different sources:

1. In 1954 Nathanael Rochester developed the "first" mnemonic #assembler for the #IBM 701 #mainframe computer that uses "TR" jump commands: shrtn.escalar.pt/ZuE5

2. In 1947 the "manual" for the #Whirlwind computer contained the "sp x" mnemonic: shrtn.escalar.pt/FdYC

So, which one was actually the "first" to use mnemonics for branching?

It’s estimated that there are 10,000 mainframes in use today. They’re used almost exclusively by the largest companies in the world, including two-thirds of Fortune 500 companies, 45 of the world’s top 50 banks, eight of the top 10 insurers, seven of the top 10 global retailers, and eight of the top 10 telecommunications companies. And most of those mainframes come from IBM.
