SMF 70-1 – Where Some More Of The Wild Things Are

(First posted February 21, 2021) As I recall, the last time I wrote about SMF 70-1 records in detail was Engineering – Part Two – Non-Integer Weights Are A Thing. Even if it weren’t, no matter – as I’d like you to take a look at it. The reason is to reacquaint you with ERBSCANContinue reading “SMF 70-1 – Where Some More Of The Wild Things Are”

Raspberry Pi As An Automation Platform

(First posted 14 February, 2021) Recently I bought a touch screen and attached it to one of my older Raspberry Pi’s (a 3B). In fact the Pi is attached to the back of the touch screen and has some very short cables.

Coupling Facility Structure Performance – A Multi-System View

It’s been quite a while since I last wrote about Coupling Facility performance. Indeed it’s a long time since I presented on it – so I might have to update my Parallel Sysplex Performance presentation soon. (For reference, that last post on CF Performance was Maskerade in early 2018.) In the past I’ve talked aboutContinue reading “Coupling Facility Structure Performance – A Multi-System View”

Automating Microsoft Excel Some More

As I said in Automating Microsoft Excel, I thought I might write some more about automating Excel. Recall I wrote about it because finding snippets of code to do what you want is difficult.

AndContinue reading “SAP And Db2 Correlation IDs”

md2pptx Markdown To PowerPoint Converter

It’s been a long time since I started writing md2pptx. But finally I’ve open sourced it. A Problem Statement Of Sorts I wrote md2pptx because I got tired of four things: The process of embedding graphics in PowerPoint. The fact that pasting a picture into PowerPoint made the resulting presentation file huge. The location ofContinue reading “md2pptx Markdown To PowerPoint Converter”
