When competitors achieve something it's a "clever trick" - when IBM finally catch up it's "innovative technology". Now I remember why I unsubscribed. Enough.

On the way home from Boston Share, I dropped in to VMWorld in Frisco. One of the sessions was a live migration of an active representative workload from mainland USA to India. In front of a live audience, with monitors running. Bloody impressive. And this was Aug/Sept 2013. Even z/VM couldn't handle things like that, let alone a 'plex. Just ask google/facebook/amazon what can be done on non-proprietary commodity hardware to keep systems up and running.

Fly me over and we can have an interview in some convivial bar. I'm willing to do it for you at "mates rates" ;-) Even at a small shop like Daves', getting through the administrative nightmare to get short term help is a dead loss. As I said earlier, I just gave up as the benefits weren't worth the hassles - why would I continue to carry the cost of professional indemnity insurance (which was never called upon in all my years) on the off-chance of getting non-permanent work ?. And what is "permanent" these days anyway ?. Shane ... -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Hmmm - things may be different elsewhere, but I have been *very* leery about getting back in the harness. What are the clients expectations ?. Not the glib head-hunter, the end client. They likely have a hole in their support team that used to be filled by someone who had been there for years and everyone felt comfortable with. Getting accepted is very hard, and you will probably be expected to be immediately useful - maybe even the expert. More so if going in as a consultant/contractor. And you won't be cut the same slack as the current incumbents that have been part of the furniture for years. I decided I could do without the grief. YMMV.

Funny the things that catch your (my) eye - was cruising and noticed this on the google mirror. Been out long enough, figured I can be a (disinterested) lurker now. I can't believe none of the Aussies subscribed have commented. Our Social Security people (whatever they are called this week) have also been getting hammered for years about their stone-age computer environment. OK, M204 is flint, but what the hell; they too run decent kit. It works, and it'd better keep working. Been there, seen it, tremble at the thought of the dills proposing it all be chucked out for SAP on Windoze or some-such ... Let's hope the proponents for Linux continue to have some wins.
