Instructor's Courses

Andrew is an all around Linux professional with in depth knowledge of the OS and this is supported with scripting in bash, perl, python and ruby and application development in C, C++ and Java. Having worked for many years in training, Andrew has developed automated course build systems after endless time wasted on Friday nights. The first build system he built was aptly named "Friday nights." This has inspired his interest in all things deployment related. He has authored training courses on Microsoft Deployment Toolkit as well as countless bespoke PXE solutions to training organizations. His commitment to the community shows in the amount of content that he has uploaded to his YouTube channel since theurbanpenguin was founded in 2009, as well as more recently helping with the Google / Raspberry Pi CoderDojo project. He also teaches Linux in schools. Over the years Andrew has taught Novell, Microsoft, Lotus Notes, Citrix, Solaris as well as Linux. It is Linux, though, where his love is. Andrew is able to help you understand how the product will fit into your organization and understand the heterogeneous environment we all work in.
