Do you see what I did there? 🙂
On March 10th I published the slides to “I Know What You Did Last Summer” on Slideshare. Since then I’ve given the presentation thrice and in the process got to know it a little.
(Yes I really do think creations take on a life of their own, sort of autonomously.) 🙂
So, six months on, I’m very pleased to have been asked to give the presentation again, but there are a couple of extra challenges in there:
- It has to fit into 45 minutes, instead of 1 hour+.
- It’s got to be sufficiently different to how it was before.
I’ll confess challenge 1 is one I should’ve addressed from the outset: You always have to be able to adapt your material to any timeslot. Yes, I can rip slides out but a “controlled contraction” would be better.
The second challenge is a blessing in disguise. The rest of this post more or less says why – and points the way to some future blog posts…
Much has happened in the past six months, some of which has been remarked upon in this blog. So the new elements I’m going to introduce are:
- Enhanced Coupling Facility Path-Level Instrumentation in RMF with CFLEVEL 18 on zEC12.
- What I’ve learned from the Usage Information in SMF Type 30.
- OA39629: NEW FUNCTION TO REPORT THE HIGHEST PERCENT OF CPU TIME USED BY A SINGLE TASK IN AN ADDRESS SPACE
The second of those I’ve already talked about. The other two belong as blog posts in their own right. Maybe “1 blog post per slide” is a good rule of thumb here.
Two other things have happened in the past six months are:
- I now have a semi-official part time role in pursuing the case for better instrumentation and talking about what we already have. I’m not sure this should be in the presentation.
- Talking to several customers and IBM developers through the summer I’m even more sure “Batch Architecture” gleaning is vital to many enterprises. So I ought to emphasise that more.
So, as I say, updating the presentation is something I want to do. And to see if I’ve made a good job of it come along to UKCMG FREE Forum on the 10th October 2012 at The Magic Circle in London.
