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”

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”

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””

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”

(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 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”

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”

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?”

After a long hiatus, I’m back with a new screencast. It’s about HiperDispatch. I pulled together the slides on a long flight back from the Far East last year and I’ve been fiddling with them occasionally ever since. Anyhow I hope you enjoy it. You can find it here.

I previously wrote about SMT in Born With A Measuring Spoon In It’s Mouth in 2016 – before z14 was announced. I also wrote about it again in 2016 in SMT – Some Actual Graphs. It’s been a year since z15 was announced so enough time has passed for me to want to write aboutContinue reading “Engineering – Part Five – z14 IOPs”
