(Originally posted 2013-02-10.) We must have over 200 iOS apps in our iTunes account. Some of them we paid for, but usually not much1, but many were free.2 I’m sure I’m not alone in wondering "how did that happen?" 🙂 It’s got well beyond the point that a new app3 simply won’t appear on myContinue reading “As It Appens”

(Originally posted 2013-01-27.) It’s been almost four years since I wrote DB2 Data Sharing and XCF Job Name. It mostly stands the test of time but there are a couple of things I want to bring up. I was in the DB2 Development lab a couple of days ago, talking with a couple of developerContinue reading “DB2 Data Sharing and XCF Job Name – Revisited”

(Originally posted 2013-01-24.) Another kernel popped the other day: SMTP / MIME. But what on earth is MiGueL Mainframe 🙂 troubling himself with SMTP / MIME for? Let’s come at this from a different angle… You probably know by now that when you send me your data it gets put through some batch reporting: UltimatelyContinue reading “Evernote, Remember The Milk, SMTP / MIME and z/OS Batch”

Specifically, turning into Part of the fun of making popcorn is watching the bag and listening to the poppings: As each kernel pops it pushes the bag out. And so it is with learning: Every piece of knowledge contributes to the overall shape. Anyhow, enoughContinue reading “Microwave Popcorn, REXX and ISPF”

(Originally posted 2013-01-13.) First, a belated Happy New Year! to everyone. It’s been a busy past few weeks, not least because of the customer situation I’m working on. But, to kick off 2013 here are the two conference abstracts I submitted for the UKCMG Annual Conference. No pressure, guys. 🙂 
 Time For DIME InContinue reading “A Good Way To Kick Off 2013 – Two UKCMG Conference Abstracts”

(Originally posted 2012-12-11.) There was a time before blogging 🙂 and what I’m about to talk about is something I used to explain quite often back in those days. Reminded by a current customer situation – and needing to explain it again – I thought it time to do it this way. (Here I’m presentingContinue reading “DB2 Timings For CICS Transactions – With Thread Reuse”

(Originally posted 2012-12-09.) I’m trying to put some structure on the idea of Life And Times Of An Address Space. The best way to do it, I think, is to attempt a taxonomy of address space types. So here’s an initial stab: One thing that immediately comes to mind is you can map useful SMFContinue reading “Two Potential New Presentations – Coming Soon?”

(Originally posted 2012-12-08.) Every year I like to debut one new presentation, though that isn’t a firm rule: In 2012 I debuted “Send In The Clones” (SITC)1 and “I Know What You Did Last Summer” (IKWYDLS), but actually only the first one was written in 2012. Of course presentations are “slow trains coming”: I widelyContinue reading “Two Potential New Presentations – Coming Soon?”

(Originally posted 2012-12-04.) I’ve talked about BPXWUNIX before but here’s a nice use case: Filtering REXX query results. When I get your performance data I have code that stores it in a database which I query with (essentially) REXX. The predicate syntax is very simplistic so I’d like to do better. I can’t replace theContinue reading “Filtering REXX Query Results With BPXWUNIX”

(Originally posted 2012-12-03.) Just a brief follow on to Bad Data And The Subjunctive Mood: Here’s a podcast I like to listen to while running. (Music and podcasts are about the only thing that keep me running, that and the success at my modest goals.) BBC Radio 4 has a very nice programme More OrContinue reading “A Nice Data Provenance Related Podcast”
