Create a Python Module
Thu, 20 Oct 2016 05:50:25 +0000
Sometime formal programming documentation is less than clear. At least, it’s less than clear until you’ve written your first solution. The Modules section of the Python language is one of those that takes a few moments to digest. Chapters 22 and 23 in Learning Python gives some additional details but not a clear step-by-step approach […]

Python for loops
Thu, 20 Oct 2016 03:02:37 +0000
It’s always interesting to explain a new programming language to students. Python does presents some challenges to that learning process. I think for-loops can be a bit of a challenge until you understand them. Many students are most familiar with the traditional for loop like Java: for (i = 0; i < 5; i++) { […]

The instance that I’ve built for my students in a Fedora VM is quite stable except for one feature. The feature is the hibernation process of the base operating system. Sometimes when the base operating system hibernates, it causes the Oracle shared memory segment to fail. When that happens you get the following error: ERROR: […]

Multitenant Architecture 12c
Tue, 11 Oct 2016 16:07:00 +0000
I thought this illustration was an interesting view of Oracle Database 12c’s Multitenant Architecture. It posted on ToadWorld.com today in a new article by Deiby Gomez and I thought it might be interesting for others. You can see how to provision a pluggable database in this article on provisioning a pluggable database. As always, I […]

Interesting beginning to OpenWorld/JavaOne yesterday. I had the chance to visit with Brendan Tierney and he gave me a copy of his new Oracle R Enterprise: Harnessing the Power of R in Oracle Database, which I went through quickly last night. It looks well written and I liked the examples. Brendan also gave me a […]
