Simplify data extraction using Linux text utilities
Simplify data extraction using Linux text utilities is a very nice article that teach how to do text magic with the Unix shell, and these commands become handy with pipe (|) operator.

ICWS Talk 2: Application of Management Frameworks to Manage Workflow-Based Systems: A Case Study on a Large Scale E-science Project
This is the second talk, and it discusses integration of Hasthi with LEAD Project, a Large Scale E-Science cyber-infrastructure.

DOI: http://doi.ieeecomputersociety.org/10.1109/ICWS.2009.52
Abstract: Management architectures are well discussed in the literature, but their application in real life settings has not been as well covered. Automatic management of a system involves many more complexities than closing the control-loop by reacting to sensor data and executing corrective actions. In this paper, we discuss those complexities and propose solutions to those problems on top of Hasthi management framework, where Hasthi is a robust, scalable, and distributed management framework that enables users to manage a system by enforcing management logic authored by users themselves. Furthermore, we present in detail a real life case study, which uses Hasthi to manage a large, SOA based, E-Science Cyberinfrastructure.

ICWS Talk 1: Enforcing User-defined Management Logic in Large Scale Systems
Early July I presented two papers at ICWS, here is the first one. This is the base of my thesis.
Citation: Srinath Perera, Dennis Gannon, "Enforcing User-Defined Management Logic in Large Scale Systems," services, pp.243-250, 2009 Congress on Services - I, 2009
DOI: http://doi.ieeecomputersociety.org/10.1109/ICWS.2009.52
Abstract: The ubiquity of information technology, technological advances, and utility computing trends have motivated largescale systems, but managing and sustaining these systems is far from trivial. Automatic or semi-automatic monitoring and control are a potential solution to this problem. However, since management scenarios differ from system to system, a generic management framework that can manage a wide variety of systems should support user-defined management logic. This paper proposes a novel architecture that can manage large-scale systems according to user specified management logic that depends on both global and local assertions of the managed system. Furthermore, the paper demonstrates that despite having a global view of the managed system, a management framework can scale to manage most real world usecases.
