(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. This is only a 7 inch diagonal screen but it’s more than enoughContinue reading “Raspberry Pi As An Automation Platform”

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”
More On Samples
This post follows on from A Note On Velocity from 2015. Follows on at a respectful distance, I’d say – since it’s been 5 years. In that post I wrote “But those ideas are for another day or, more likely, another year (it being December now).” This is that other day / year – asContinue reading “More On Samples”
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. So if I can add to that meagre stockpile on the web, I’m going to. That other post was about automatingContinue reading “Automating Microsoft Excel Some More”
Mainframe Performance Topics Podcast Episode 27 “And Another Thing”
So this is one of our longest episodes yet, but jam full of content which is very us. As usual, finding times when we can both be available to record was tough. What wasn’t difficult was finding material. I can say for myself what we talked about is a set of things I’ve wanted toContinue reading “Mainframe Performance Topics Podcast Episode 27 “And Another Thing””
SAP And Db2 Correlation IDs
Every so often I get to work with a SAP customer. I’m pleased to say I’ve worked with four in recent years. I work with them sufficiently infrequently that my DDF SMF 101 Analysis code has evolved somewhat in the meantime. The customer situation I’m working with now is a good case in point. AndContinue reading “SAP And Db2 Correlation IDs”
Automating Microsoft Excel
(This post is about automating Excel on Mac OS. If you’re not a Mac user this probably won’t interest you.) My Process From the creation of a CSV file onwards, automation is key: Creating a CSV file is one of two things: A program on z/OS. A piece of javascript code I have that turnsContinue reading “Automating Microsoft Excel”
mdpre Markdown Preprocessor
mdpre Markdown Preprocessor A few days ago I released md2pptx, a Markdown to Powerpoint converter on GitHub as an open source project. You can find it here. Now I’m releasing a companion program – mdpre. This is a preprocessor for Markdown. You can find it here. I would’ve released them together and why I didn’tContinue reading “mdpre Markdown Preprocessor”
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”
What About The Others?
I just produced a new chart, which I think is worth sharing with you. I produced it for one specific use case, but I think it has slightly wider applicability. The Trouble With Outsourcers Quite often we get performance data from outsourcers, whether IBM or some other organisation. Generally they’re running LPARs from more thanContinue reading “What About The Others?”
