Some of my students want to learn to write C++ on a Windows OS. At some point, you simply surrender to the fact that many people prefer the Windows OS as a starting point. Traditionally, I’d recommend the Microsoft Visual Studio as their learning vehicle because it’s free to our students because of our relationship with Microsoft. It’s not free to graduates. When a graduate contacts me I recommend Code::Blocks. Just recently, one ask for more than a recommendation. He wanted instructions. These are the instructions.
We often use NULL values in date ranges, usually in the end date to signify the indefinite future. I have decided that this is a bad idea; here are my reasons.

New update of VMWare came out, and it is time to upgrade VMWare Tools. Here’s an update on the instructions for upgrading VMWare Tools:
Last week, at the yearly ODTUG Kscope Conference, I did my presentation "Getting Started with APEX Plugin Development". After the session Patrick Wolf, Principal Member of Technical Staff for APEX, pointed out an improvement that could be made.

The morning started nice, ODTUG organized breakfast with country themes. There were tables for Australia, Canada and The Netherlands. If you are Dutch you might have expected to have hagelslag or cheese, this was not the case. It was a nice and hearty American style breakfast, eggs, bacon, potatoes.
The first session of the day that I went to was by Nathan Catlow on Oracle APEX Security, an interesting topic.
Mark Drake, the product manager for XMLDB and the new JSON features in the database, started Tuesday with a session on flexible storage.
After a short history of the XMLDB ("more than just a LOB Store"), he went to the heart of the presentation: flexible storage.
Monday morning started with the opening keynote. At the same time the Dutch soccer team played Chile (which the Dutch won with 2-0). A small Dutch delegation went to watch the game, all dressed in orange, I was one of them.
During the keynote the location of Kscope 2015 was announced: Hollywood, Florida.
Lunch was special, there were lunch and learn. There were "reserved" tables were you could sit on and talk tech with ACE Directors. We had some nice discussions at the table that I sat on, including the soccer game.
