Quadrant Framework – rev7 updat...
Quick update to the framework that was released yesterday; I’ve added automatic graph generation. I chose DyGraphs due to the quick ability to enable support – the HTML is very quick and simply loads the CSV data. It has the same zooming features of Highcharts without the JS overhead.
Now when you run a load test you will get (i [...]
MySQL Community – what do you w...
So I’ve been doing a fair number of automated load tests these past six months. Primarily with Sysbench, which is a fine, fine tool. First I started using some simple bash based loop controls to automate my overnight testing, but as usually happens with shell scripts they grew unwieldy and I rewrote them in python. Now I have some fle [...]

This month is a special month. It’s not because of Valentines day or even the exciting day where we see groundhogs. No, this month is special because I’m have a book contest where you, the reader, get to win something free for doing absolutely nothing more than posting a comment saying that you want one of the several books I ha [...]
Python for Automation: using pdsh for...
I’ve been playing around with some quick system automation scripts that are handy to use when you don’t want / need to setup a chef or puppet action. I like to keep all of my hostnames and login details in a MySQL database (a cmdb actually) but for this example we’ll just use a couple of nested lists. This script executes [...]
Review: MySQL for Python by Albert Lu...
Packt Publishing recently sent me a copy of MySQL for Python to review and after reading through the book I must say that I’m rather impressed at the variety of topics that the book covers.
It starts off with the basics of setting up MySQL for your testing/development needs by going over several of the common installation and configu [...]
Simple Python: a job queue with threa...
Every so often you need to use a queue to manage operations in an application. Python makes this very simple. Python also, as I’ve written about before, makes threading very easy to work with. So in this quick program I’ll describe via comments, how to make a simple queue where each job is processed by a thread. Integrating this [...]

If you’ve been looking for a simple python script to use with MySQL that you can use to expand upon for your next project, check this one out. It has error handling for the connection, error handling for the sql call, and loop iteration for the rows returned.

Reviewed: Python Testing by Daniel Ar...
I’ve recently had the pleasure of reading “Python Testing: An easy and convenient approach to testing your python projects” from Packt Publishing. It’s been a quick read but a solid set of instructions on the different methods for the subject.
The book starts out very quickly with details about the various methods t [...]

Saw this interesting paper about highly concurrent programming methods and figured the word should be spread! It’s not new material but it’s a good read. See the full article here: http://www.usenix.org/events/hotos03/tech/full_papers/vonbehren/vonbehren_html/

I’ve recently been migrating my wiki/documentation for Kontrollbase to Trac. For those that are not aware, Trac is a web-based documentation/wiki/Subversion tool that is used by countless number of software projects. Subversion, of course, is a software collaboration and code management repository that manages branches/tags/trunk file [...]
