November Lunch Meeting

How can Web Services be saved from themselves?

Speaker: Paul Gordon, PhD student, University of Calgary

Technological advancements in IT are usually met with inflated expectations, followed by disillusionment. The niche for a technology eventually become apparent, and this is just starting to become the case in Web Services, where calling one service is easy, but combining them for real-life tasks is very hard. How might emerging technologies such as the Semantic Web and end user content creation technologies (a.k.a. "Web 2.0") improve the way we interact with Web Services? In this presentation we will explore where Web Services failed, and how semantic and social engineering may lead to better Web Services interoperability within communities such as industry groups and scientific fields. The implementation of semantically enabled Web Services in the field of Genomics research will be used as an example of the technical requirements, the computational possibilities, and what such an IT ecosystem will look like to the end-user.

October Lunch Meeting

Technical Sharing


  • Seismic Software Enhancements through XMLification

    Alan Dewar
    How the introduction of XML into a seismic data processing system made life easier for both developers and users.
  • PXE: Booting up x86 OSes without media

    Yves Dorfsman
    PXE allows x86 based machines to boot over the network, allowing you to install or preview Operating System without having to use a hard media (CD, DVD). This is a quick overview of how to set it up, and which current OS'es support it easily.
  • Configuration Management

    Harold Ditchfield
    Introduction to Configuration Management and an overview of Puppet.
  • Why is encrypted mail such a colossal failure ?

    Hrvoje Lukatela
    In a protracted 4-party (two companies, two sets of lawyers) negotiations that required a fair degree of confidentiality where a lot of the communication was done via e-mail, Hrvoje's proposal to start using either GPG or an extremely simple symmetric "home-brew" system went nowhere fast. That got him thinking: if we need (and obviously, we do!) a "better mousetrap" what would be it's characteristics?

    Hrvoje is not proposing a solution, but would like to start a discussion on this topic. He will be presenting what is available today and what problems he ran into.
