    Going through the tutorials there are a few elements that are not necessarily obvious for Ubuntu users. In particular, the connector for MySQL and PIP

  • Connecting Zurmo, SurveyGizmo and ifbyphone

    One of the tasks that I have to work on, and would like to document for the future is the interoperation of Zurmo (CRM software), SurveyGizmo (Survey Software) and ifbyphone (IVR and Call Recoding Software).

  • Ruby vs. Python
    Mon 10 December 2012

    With R, I have reached a plateau where solving problems is essentially a trivial matter. Although R provides facility for performing functions outside of data analysis there are a number of elements relating to integration with the web where it simply cannot manage everythihg.

    Sun 09 December 2012

  • Scraping tables from the web
    Fri 02 November 2012

    If, like me, you do a bit of work with mutual fund data across a number of sources, you'll eventually need to pull in the dealer codes or the fund codes. Below is a working example of how to pull in active dealership codes

    Sun 12 August 2012

    On a fresh install of Ubuntu 12.04, the default text editor is gedit. While gedit is a great program, it is not as full featured as Geany. If you'd like to change this, run the following
