Lev Lafayette has an MBA (Technology Management) from the Chifley Business School, where he was on the Dean's List, a Graduate Certificate in Project Management from the same institution, and an honours degree from Murdoch University in Politics, Philosophy and Sociology which is commented upon by the Vice-Chancellor of the time. Many years later he completed a Graduate Certificate in Adult and Tertiary Education at the same institution.
He is a certified PRINCE2 Practioner, and an Adult and Workplace Trainer. Clearly not satisfied with one masters degree, he's started another, this time a Master of Education at the University of Otago. With a interdisciplinary approach, Lev's interests include the political implementation of universal pragmatics, the relationship between communications technology and society, and comparative economic systems. On again and off again, he plods his way through completing a PhD in Social Theory as well.
Professionally however, Lev is an experienced systems administrator, specialising in the Linux operating system and scientific applications, a project manager, systems engineer, and quality management systems coordinator, specifically for ISO 9001 (Quality assurance) and ISO 270001 (Information Technology Security). He also does a lot of training for researchers and technical staff in Linux, High Performance Computing, mathematical programming, Postgresql, and related subjects, with graduates and post-doctoral learners from a variety of organisations including: RMIT, La Trobe University, the University of Melbourne, Deakin University, Swinburne University, Victoria University of Technology, the University of Sydney, Macquarie University, the University of New South Wales, the University of Western Australia, the Australian Institute of Health Innovation, the Westmead Millennium Institute, and the Australian Institution of Marine Science.
Previous employment and clients include several years working as a computer systems trainer and database management for the Parliamentary Labor Party in Victoria. Following this he worked for the Ministry of Foreign Affairs in Timor Leste (East Timor) managing their computer network and providing training and technical expertise to that Ministry in their first year of self-governance. Dr. Ramos-Horta provided the following comments on his work.
Lev works for the Victorian Partnership for Advanced Computing as a systems administrator for Linux clusters. As per that organisation, this site is mostly dedicated to issues concerning High Performance Computing, Scientific Computing and Supercomputing. Lev is involved in Linux Users of Victoria, having spent four years as President, two years as Public Officer, two years as Vice-President, a year as Treasurer and is now in his second years as an ordinary committee member.
The crocodile logo was designed by Victoria Jankowski. It was first used on the cover of Neon-komputadór, the first IT training manual for the Ministry of Foreign Affairs in East Timor which was printed and translated by the United Nations Development Programme. The crocodile represents the Timorese people and is the emblem of their land. The integrated circuit represents their independent connectivity to the wider world.
You can also find a political site that Lev subscribes to, The Isocracy Network, a synthesis of several progressive political orientations, and RPG Review which covers his interests in roleplaying and simulation games. As a secular humanist with an interfaith perspective, he manages and contributes to the Lightbringers website. He also has a livejournal, which will probably be quite boring to anyone who doesn't know him personally.
That's enough of me talking about myself in the third person like Cerebus The Aardvark.

High performance computing is a necessity for scientific research and increasingly so; however initial steps are also being made in vocational engineering at RMIT. Applying the andragogical principles in the education sector with free and open source content encourages educational connectivism which improves learning and relevance.

Julia is a high-level, high-performance dynamic language for technical computing. With a "just in time" compiler, it is very fast, especially compared to languages like MATLAB, Octave, R etc. However it is relatively new and a cluster installation and package deployment has a few quirks.
Download the source from github. By default you will be building the latest unstable version of Julia from the git checkout. However, we want to run 0.4.0 (or rather, 0.4rc4) which is the last stable release.
# cd /usr/local/src/JULIA

Many Android devices come with storage configurations that are surprising to end-users. A product that is advertised as having 32 gigabytes of memory may in fact turn out to have much less available in terms of installing applications.

Mr. Bayes is a program for Bayesian inference and model choice across a wide range of phylogenetic and evolutionary models.
Download, extract. Note that the developers have produced a tarbomb which will require a separate directory created before download. This has been raised as a bug.
Note that more recent versions of MrBayes make much better use of autoconfiguration tools.
