An alternative summary of my work history in Tabular Form is available.
In February 2011, I joined IPExchange in a systems administration role. My initial mandate was to rebuild its VMWare infrastructure. In addition to running the systems of a small datacenter, I worked on projects for IPX's sister business - TV Plus - which provides Serbian satellite TV services to Australia. Some of these projects included:
During 2009 and 2010 Clarinet was slowly restructuring itself into a new business of appointment reminders. This was being done concurrently with operating the ISP.
I developed the Mercumer online appointment reminder system. This combined JS, AJAX, PHP, Perl and MySQL to create a an online application that would be familiar to users of Windows and Mac OS X. We employed, the principles of User Centred Design, custom tools - where needed - and the use of the most appropriate language for the task to produce an effective tool to help small businesses communicate with their customers.
In August 2008, Ustel went into liquidation and Daniel O'Callaghan and I returned to the ISP business by aquiring the hosting and some of the ADSL services from Ustel.
In October 2007, Daniel O'Callaghan and I sold the Clarinet Internet Solutions business to Ustelecom. Subsequently, I have been consulting to Ustelecom and Ustel on various projects including modifications to their 3rd party billing system and the creation of a new customer credit checking interface.
At the beginning of 2005, I began fulltime employment with Clarinet Internet Solutions in the roles of Director, manager and technical expert. In addition to Clarinet, I helped found a new telecommunications carrier Blitzwave. This carrier focuses on the wholesale market and Clarinet will resell Blitzwave's services. Blitzwave will use a variety of wireless technologies to deliver services to its client ISPs. My business partner, Daniel O'Callaghan, and I sold the Clarinet business to Ustelecom in October 2007. At Blitzwave I developed the initial ICP (Interception Capability Plan) and many of the other compliance documents and policies.
From March 2006, I have served as a consultant to the Australian Flexible Learning Framework Access to Bandwidth project. This project is targeted at improving broadband connectivity for the Vocational and Technical Education (VTE) sector. In this role I provide expert guidance relating to Internet Protocols, routing and the structure of the Australian Internet industry.
In 2004, I returned to RMIT, working for the Research and Development Unit of the Business Faculty, part time. In this role I worked with the Smart Internet CRC on Users and Digital Rights Management. The team consisted of lawyers, qualitative researchers and computer scientists. A spin off from the work was an examination of the methodology of computer scientists and multidisciplinary teams.
Concurrent, with my work at RMIT, I worked with Clarinet to:
From the closure of the Sofware Engineering Research Centre until December 2003, I worked with the Department of Mathematics and Statistics at RMIT in a part time capacity as a Senior Research Fellow. In this position I supervised students, assisted in commercialisation of a research project and conducted computer security research.
From 1999 until March 2003 I was employed as a Senior Research Fellow at the Software Engineering Research Centre (SERC), RMIT in Melbourne, Australia. SERC is a small research centre which had at its peak 7 full timestaff and up to 14 students and visitors at a time. Previously I was employed by the Department of Computer Science, Faculty of Applied Science, RMIT as a lecturer.
At SERC I was engaged in developing technologies, methodologies and tools to assist in the development of code in parallel functional languages, the development of a software and hardware architectures forparallel computers, the application of cryptographic algorithms and the development of Internet security methodologies and applications.
In addition to my academic interest in software and systems, I have practical experience in the crafts of software creation and systems administration.
I was an active participant in the Smart Internet Technology CRC (SITCRC), fostering interactions between the technology programs and User Needs program. Before joining the SITCRC, I was involved in the setting up of SERC's involvement with Australian Telecommunications CRC.
In 1996 I was awarded a PhD by Monash University, Melbourne, Australia. The work was conducted under the supervision of Prof Chris Wallace and my thesis was entitled `The Walnut Kernel: A Password-Capability Based Operating System'. This thesis dealt with the development of a capability based operating system which provides a known level of security and supported the user paradigm of persistent memory objects.
While working on my thesis I assisted in the high level design of hardware to support an easily scalable multiprocessor. Together with Dr Ronald Pose I developed a mechanism to overcome many of the physical difficulties found in constructing large multiprocessor machines. The mechanism which eliminated from the design global clocks and their inherent problem of distribution over a wide area.
In 2004 I was awarded an MBA by University of Melbourne, Melbourne, Australia. I was a member of the 2004 cohort of the Melbourne Business School studying full time.
From 1996 to 1998 I taught CS382 Software Engineering Project. This course takes both industry and university originated projects. The projects are tackled by a number of small groups of students (less than 6). Each group builds a working product within two semesters.
In 1998 I revised CS584, the Real Time and Concurrent Systems course, to have a more practical focus and use Erlang as a language for students to implement real time systems.
Also in 1998 I took over the teaching of CS470, Software Creation and Maintenance. This course is taken by both masters students and undergraduate students. The eclectic range of topics covered in lectures are based on the theme of making students productive immediately in Industry. The course addresses the pragmatic issues of: debugging, testing and maintaining software.
In addition to teaching these subjects I am assisting Prof Fergus O'Brien with the CS474 Software Architecture course. This course examines a number of potential software architectures and requires students to implement a project using an architecture of their choice.
In 1997, I provided tutorial assistance for a collection of courses including CS544 Interactive Digital Media - a Java based course, CS100 First year Computer Science - an Ada based course, and CS470 Software Creation and Maintenance.
In 1996 I taught CS584. The CS584 Parallel and Real Time Systems course focused on Hoare's Communicating Sequential Process (CSP) model of parallel systems. In addition to developing the theory of CSP the course included practical work using the functional programming language Erlang.
In the first half of 1994 I taught The Computer Architecture (CSC2010) course in the Department of Computer Science, Monash University. This course covered equally the areas of assembly language programming and basic computer architecture.
In 1998 I wrote a book to support the new look Real Time and Concurrent Systems course. The book describes the Erlang programming language and its application to that domain.
Because of the lack of documentation covering the use of AT&T syntax assembly code on the Intel 80386 processor, I produced material to assist students in the 1994 course. The material covers the syntax, and mnemonics of the 80386 assembler (GNU as) used in the course, low level programming practices and techniques, floating point arithmetic, computer components including processor internals, DMA devices and IO devices, and introduced the R2000 processor for comparative study with the 80386.
In 1995 this material was published as a book and used to support the course. It was amended and republished for use in the 1996 course.
In addition to these projects I was the maintainer of the R statistical language port and GNAT Ada port for the FreeBSD project.
I have also created a number of programs for use under the EPOC operating system (an operating system created by Psion and now marketed by Symbian). EPOC is an operating system designed for use in PDAs and mobile telephony products
For various reasons I run the computer systems that support SERC. We run a mixture of Solaris and FreeBSD machines. Although this activity takes up much more of my time than I wish it has given me insights into the practical application of operating systems and the all too human face of system administration.
In addition to my academic pursuits I was a director of HiLink Internet Pty Ltd (later Clarinet Internet Solutions) until 1999. This company was formed in 1996 from a partnership started in 1994. The company focuses on providing innovative solutions to businesses and individuals in Victoria in the area of Internet connections, security and consulting.
Maurice joined the Victorian chapter of SAGE in 2005 and has served as a general regional executive member since August 2006. In 2016 SAGE-AU became the ITPA Information Technology Professionals Association.
I also ballroom dance, nordic ski and ride horses.
