DFSORT - Now With Extra Magical Ingredients
Thanks to Scott Drummond for reminding me of last Autumn's DFSORT Function PTFs - UK90025 and UK90026. They're mentioned in the preview for z/OS Release 13 so now is not such a bad time to be talking about them. So let me pick out a few highlights: Translation Between ASCII And EBCDIC, And To And From Hex and Binary For a long time DFSORT has been able to translate to upper case (TRAN=LTOU), to... [More]

HTML5 Up and Running - A Review Of Sorts
William Gibson's "The future is already here — it's just not very evenly distributed" applies very well to HTML5. It's even more true of CSS3. Despite that (or maybe because of it) it's a good time to dive into HTML5 - before everyone else does. So, a few months ago I bought, read and inwardly digested Mark Pilgrim's HTML5 Up and Running , published by O'Reilly in August 2010. I have a... [More]

My Slides Are Ready For Vienna
I wouldn't want you to decide not to come to Vienna , just because I've made my slides available on Slideshare: I'd hope you'd come to Vienna anyway. It's a great place and it's going to be a great conference. Lots of people can't make Vienna and I don't suppose having the slides to hand is going to tilt the playing field significantly away from coming if you weren't going to anyway. I don't... [More]

I'm A Sucker For Ingenuity
Every once in a while I come across a particularly good idea: Where someone has done something particularly clever to solve a problem. Here's one very recent example: On the iPhone (and iPod touches) you can only display icons. They can be augmented with a numeric counter, but that's all. (The idea is the app shows you the number of unread emails, for example.) But here's the idea, in a nutshell:... [More]

Batch Architecture, Part One
First a word of thanks to Ferdy for his insightful comment on Batch Architecture, Part Zero . And also to my IBM colleague Torsten Michelmann for his offline note on the subject. As I indicated in Part Zero I hoped to talk about jobs in a subsequent post. And this is that post. In particular I want to discuss Viewing jobs as part of distinct applications, and Generating a high-level understanding... [More]

IBM System z Technical University - Vienna, May 2-6
I'm working on my presentations for System z Technical University - Vienna, May 2-6 and I'm reviewing the agenda. As well as my four presentations there are lots of other goodies. These range from the Management level down to the purely technical. (I guess mine are towards the latter end of the scale - but I'd say there's lots of pressure on us all to work on cost so detailed information on e.g.... [More]

Experimenting With QR Codes
Inspired by two of Bob Leah's posts on QR Codes - here and here I started experimenting with creating and consuming QR codes. But what is a QR code? In short it's a two-dimensional barcode that can contain e.g plain text or a URL. In the latter case a QR code reader can pick up the URL - maybe from a real-world object - and open it in a browser.
Creating QR Codes In my experiment I created the... [More]

Memory Metrics - An Overdue Update
In 2007 I posted twice on memory metrics. The original posts are Memory Metrics Now That z/OS Release 8 Is Upon Us and Mor(e )on UIC I should probably have posted an update some time ago. In the latter I said "Obviously copious free frames would suggest no constraint." That's true but I would invite installations to consider something else... Capturing a dump into virtual memory backed... [More]

Batch Architecture, Part Zero
I'm not an architect. I don't even play one on TV. In fact real architects would probably say I'm in the babble phase, architecturewise . But I've been involved in a few situations over the past year or so (and I'm involved in a couple starting round about now) which have led me to the following simple conclusion: Many installations would benefit from drawing up a Batch Architecture . I don't... [More]

Do You Like The New Look?
I hope you do. Special thanks are due to Bob Leah, Victoria Ovens and David Salinas for getting me this far: Bob created the new template I'm using (and it is discussed further here . Victoria created the new blog header graphic (of a z196 and a zBX) and David put it up for me. You'll have noticed I'm also blogging again - after a gap of about a year. (I talk about that somewhere in the middle of... [More]
