Although this is not my main occupation (I am primarily a businees man), I am also in charge of the computer architecture for a small company. I run and maintain several Ubuntu servers for that purpose (including mail, file, calendar servers). I also develop internal applications. This includes a (very) small ERP in PowerBuilder with MySQL backend. Another part of the activity is to write and maintain Python programs to create DB reports daily sent by mail, to read production data received from suppliers files and written to the DB and to send information to external official servers (using PYCURL).
