Thanks to a certain recent Open SSL bug there’s been a lot of attention paid to passwords in the media. I’ve been using KeePassX to manage my passwords for the last few years so it’s easy for me to find accounts that I should update. It’s also a good opportunity to use stronger passwords than ‘banana’.
In the previous post I introduced obi-metrics-agent, an open-source tool from Rittman Mead that can collect DMS metrics from OBIEE and write them to several formats including graphite. Graphite is a tool for storing and graphing time-based metrics.
Now in this post we will look at how to install the tools and get them up and running on your server. The install process has been tested on both OL5 and OL6 (and so by (more...)
Understanding what is going on inside OBIEE is important for being able to diagnose issues that arise, monitor its health, and dig deep into its behaviour under stress in a load test. OBIEE exposes a set of metrics through the Dynamic Monitoring Service (DMS) and viewable through Enterprise Manager (EM) Fusion Middleware Control. EM is a great tool but doesn’t meet all requirements for accessing these metrics, primarily because it doesn’t (more...)
Please consider participating in TRUCEConf (March 18-19 in Cincinnati)!
The goal is to help the tech community heal, through learning from others outside our industry and having an open dialogue and on how we can be better humans to each other in the world of tech.
You may remember fierce controversy around TRUCEConf when virtually nothing was known about it but its name; without solid information, it was easy to read bad connotations into the (more...)
After reading this fine summary of the history of Python 3 by Nick Coghlan I was inspired to update as many of my half finished projects and miscellaneous scripts as possible. Then I looked up and I had lost several hours of my life. To save random internet strangers from the same pain as I experienced here is a catalogue of problems and how I solved them.
tl;dr – Python 3.3 on Ubuntu 12. (more...)
I'm looking for collaborators who want to build web programming experience on an interesting project...
During my job search, I was contacted by Kai Schraml, a seminary graduate who wants to scratch an itch. Seminarians have a serious need to discuss, debate, and seek consensus on the translations of (more...)
I'm happy to say that I'll shortly be starting a new position as a PostgreSQL DBA and Python developer for Zoro Tools!
We software types seem to have hardware envy sometimes. We have "builds" and "engines" and "forges" and "factory functions". But as it turns out, the "Tools" in "Zoro (more...)

IPython for non-Pythonistas
Break out of your (bash) shell! IPython and the IPython Notebook have swept over the Python programming community, but they're not just for Python programmers - they make for high-powered shell (more...)
The Midwest Python Workshop for women and their friends is back! We've got new workshops scheduled, ready to take new batches of students:
I'm available for hire! If you need a database expert with lots of programming skill, or a Python programmer with deep database experience, please check out:
But: you must be telecommute-friendly, or in the Dayton area. I'm sorry, but I'm not available to relocate.
At Monday's after-PyOhio sprint, I changed ipython-sql from an IPython Plugin to an Extension; this makes it compatible with IPython 1.0. Fortunately, this was really easy; mostly I just deleted Plugin code I didn't understand anyway.
Loved PyOhio once again! Thanks so much to everybody who came, participated, and made it happen! I get such a rush of joy from seeing the Ohio Union fill up with happy Pythonistas.
PyOhio has been a classic case of the Stone Soup story. When we started planning the first (more...)

When I upgraded from Xubuntu 12.10 to 13.04 today, all my existing Python virtualenvs broke! Fortunately, they're just virtualenvs and easy to replace (that's kind of the point). But don't panic if you start seeing these.

For my newest ipython-sql trick, I needed to compare some queries run across different databases. How hard would it be to get side-by-side results into tidy IPython Notebook output?
Not hard at all, it turns out, if you're willing to violate basic principles of human decency.
That's an itty-bitty image, (more...)
