Want a free Data Studio book?

IBM Data Studio if you don't know is a free tool for administering and developing server side / app routines for DB2 (both LUW and z/OS).

iPad, Wifi HD TV and honorarium? What the heck is an honorarium?

A sticky on the DB2 Express-C forum reads:

Provide your input on DB2! Honorarium for completing survey

I had heard of honorary degrees and aquariums but what the heck is an honorarium? I didn't think they meant an honorary aquarium (not even sure what that is) so I decided to look it up and the first hit wikipedia described it as "an ex gratia… Continue

Its bit of a walk getting to the convention area even if you take the tram, well those staying at the Mandalay Bay will probably agree too. But its a big conference ... with over 7000 attendees, and takes more than one hotel to accommodate everyone.… Continue
