About Lev Lafayette

Crocodile Logo

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 researchers from a variety of organisations including: RMIT, La Trobe University, the University of Melbourne, Deakin University, Swinburne University, Victoria University of Technology, Monash University, the Australian Synchrotron, the Department of Environment and Primary Industries, 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, the Australian Radiation Protection and Nuclear Safety Agency, 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 Research Platforms group at the University of Melbourne as the Senior High Performance Computing Support and Training Officer, and prior to that Victorian Partnership for Advanced Computing, as a systems administrator for Linux clusters. As per those roles, 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 third year as an ordinary committee member. He is has a coordinating role in the annual Multicore World conference and typically take the role of MC.

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, including as editor of the namesake journal. This includes being the author of one very ironic RPG (Papers & Paychecks), a co-author of another (Fox Magic, author a supplement (Rolemaster Companion VI), as well as plot and character development in the computer game Cargo. He has also been a playtester for RuneQuest, Traveller, Basic Role Playing, and Eclipse Phase.

As a secular humanist with an interfaith perspective, he manages and contributes to the Lightbringers website which includes various addresses and essays on philosophy and religoin.

Finally he also has a livejournal account, 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.

Not The Best Customer Service (laptop.com.au)

You would think with a website like laptop.com.au you would be sitting on a gold mine of opportunity. It would take real effort not to turn such a domain advantage into a real advantage, to become the country's specialist and expert provider of laptops. But alas, some effort is required in this regard and it involves what, in my considered opinion, is not doing the right thing. I leave you, gentle reader, to form your own opinion on the matter from the facts provided.

New Developments in Supercomputing

Over the past 33 years the International Super Computing conference in Germany has become one of the world's major computing events with the bi-annual announcement of the Top500 systems, which continues to be dominated in entirety by Linux systems. In June this year over 3,500 people attended ISC with a programme of tutorials, workshops and miniconferences, poster sessions, student competitions, a vast vendor hall, and numerous other events.

Exploring Issues in Event-Based HPC Cloudbursting

The use of cloud compute, especially in proportion to single-node tasks, provides a more effective allocation of financial resources. The introduction of cloud-bursting to scheduling systems could ideally provide on-demand compute resources for High Performance Computing (HPC) systems, where queue wait-times are a source of user consternation.

Transparency and Immersion in HPC

The development of the graphic user-interface is widely considered a major phenomenological contribution to the Human-Computer Interaction (HCI) by providing an intuitive framework for data storage and processing, encapsulated in the term "user friendly". Whilst for a very large number of everyday computational tasks this Windows-Icons-Menu-Pointer (WIMP) interface has been highly successful, the field of high performance computing (HPC) continues to use the command line interface.

International HPC Certification Program

The HPC community has always considered the training of new and existing HPC practitioners to be of high importance to its growth. The significance of training will increase even further in the era of Exascale when HPC encompasses even more scientic disciplines. This diversification of HPC practitioners challenges the traditional training approaches, which are not able to satisfy the specific needs of users, often coming from non-traditionally HPC disciplines and only interested in learning a particular set of skills.

Being An Acrobat: Linux and PDFs

The PDF file format can be efficiently manipulated in Linux and other free software that may not be easy in proprietary operating systems or applications.

Installation of MrTrix 3.0_RC2 on HPC Systems

MrTrix is "a set of tools to perform various types of diffusion MRI analyses, from various forms of tractography through to next-generation group-level analyses". It is mostly designed with post-processing visualisation in mind, but for intensive computational tasks it can make use of high-performance computing systems. It is not designed with messing-passing in mind, but it can be useful for job arrays.

Net Promoter Score: The Most Useless Metric of All

A number of organisations use a customer service metric known as "Net Promoter", first suggested in the Harvard Business Review. Indeed, it is so common that apparently two-thirds of Fortune 500 companies are using the metric. It simply asks a single question: "How likely is it that you would recommend [company X] to a friend or colleague?".

Drupal "Access denied" Message

It happens rarely enough, but on occasion (such as an upgrade to a database system (e.g., MySQL, MariaDB) or system version of a web-scripting language (e.g., PHP), you can end up with one's Drupal site failing to load, displaying only the error message similar to:


PDOException: SQLSTATE[HY000] [1044] Access denied for user 'username'@'localhost' to database 'database' in lock_may_be_available() (line 167 of /website/includes/lock.inc).
