Virtual Machine Reset Vulnerabilities and Hedging Deployed Cryptography
Monday, December 13, 2010
Presenter: Scott Yilek, University of St. Thomas
While virtualization has increased the reliability of online services as well as the ability for individuals to back up their whole system without being complete worried about losing everything in case of a complete system failure, despite the high rate of success and applicability, some problems have developed from the use of virtualization. Dr. Yilek showed us how virtualization could result on a system being compromised and secret signing keys revealed after the startup of a virtualized system. Virtual Machines started in the 1960s (IBM) and are currently used today by Amazon web services, windows azure, sun virtual box, vmware, among others. They have since contributed substantially to the current boom. Virtualization allows for the emulation of virtual hardware. As such, hundreds of machines can be in one physical machine.…
Article Reviews – Length of Online Course and Mobile Phones
December 12, 2010
(Practice of Dr. Hendel’s article analysis example) In the process of becoming a more efficient critical reader, not only am I interested in finding articles that appear interesting, but as important is the evaluation of the quality of the material. With only a limited amount of time available and a greater amount of books and articles being published on a regular basis it is important to filter as much data as possible as quickly as it can be filtered. To further understand the objective of the article and its researchers, I searched (googled) the authors to learn about their background and what research they had previously worked on. After learning more about the main authors experience with orphanages in South Africa, I became also interested in that area of her work. I was unable to find who the person had studied under or where.
Looking at the end of the article, I did not find any information regarding grants or any outside the university support for the publication.…

Analysis Engines
Monday, December 6, 2010
Presenter: Mike Whalen – University of Minnesota Software Engineering Center
During the most recent colloquium Mike Whalen, a professor and researcher at the Software Engineering Center spoke about the need to debug or look for errors within programs through a more holistic and comprehensive approach. While traditional debugging will detect many flaws, so flaws are hard to differentiate from properly written code. During his lecture he decided not to talk specifically about medical devices. He currently receives support from NASA, the Air Force, Lockheed as well as other major corporations.
One of the first issues that Dr. Whalen addressed was an in-depth overview regarding how software is traditionally developed. He outlined the following parts in the design: concept formation, requirements specification, design, implementation, integration, system. Within traditional software developing a large portion of the costs are allocated to testing, where the unit test, the integration test, and the system test can account for up to 75% of the budget.…

ICT and the Digital Divide – A Participatory Solution with a Dominican Flavor

The Digital Divides – The Ownership of Knowledge in the 21st Century
The “digital divide,” a term coined in the late 20th century, highlights the growing disparity in access to information and communication technologies (ICTs) between and within countries (Norris, 2001; Compaine, 2001; Warschauer, 2003). This concept, its meaning, and its implications for states across the world have been topics of widespread research and debate since the beginning of the 21st century (OECD, 2000; Attewell, 2001; Goldfarb & Prince, 2007; Katz, 2008; Trucano, 2005; Mar, 2004; Chapman & Mahlck, 2004). Within the United States and abroad, public libraries and public computing centers have attempted to diminish the gap between technology haves and have-nots, yet many still lack access to computers, broadband Internet, and even mobile phones (Krebeck, 2010; InfoDev, 2010; The Economist, 2010; The Economist, 2005; Richardson et al.,…

iPad Initiative (Research)
iPad Research Questions Themes
CEHD Research Team
12/03/10
The Student Experience
- How did the use of the iPad affect student interest and engagement?
- Qualitative: What was the student experience using iPads in classes?
- How are students using iPads in and out of class?
- How much time do students spend using their iPads for different purposes (social networking, studying, gathering material)?
- How does the possession of the iPad influence the perceived and actual accumulation of cultural capital for all students? Students of Color?
- How does it impact positioning in the classroom?
- How does the possession and ability to use the iPad promote a feeling of importance and capacity for students? How does this transfer into other academic contexts?
- Were there any differences in student learning among different student population groups? (ex; perhaps access to this technology serves as advantage for historically disadvantaged student groups such as first-generation, low income groups)
- How did the students learn to use the iPads?
Participation in Inter/national Development Discourse and Practice

Vertical case study approach – How participatory discourse matters.
Argument: Cultural politics continue to impede “the rich promise of participation” (pg94) She relates Brazil social problems and high level of inequalities to the colonial era – Carvalho (2002). Problems included: “concentration of political, economic, and social resources among the elite and the distortion of representative government by favoritism, institutional opacity, and unequal resource distribution.” – pg 96 |
Public primary schools served as “repositories of and incubators for the Party’s democratic goals” – “Citizen School Project” – (pg 94)
Members of the School Council could be up to 18 and were linked to the size of the school. |

U-Lead Global Programs – GYLCE Argentina
December 1, 2010
1 – Academic content of this course and how it relates to the chosen country
The Global Youth Leadership and Community Engagement (GYLCE) course explores the prosocial, active roles that young people play in advancing their communities and the broader society. The course explores the history, purposes, and structures of youth engagement, leadership, and empowerment work across the globe. Perhaps the most robust approaches to youth engagement are found in Latin America, most notably in Argentina. Argentina operates a program in solidaria for youth through their aprendizaje-servicio initiative within the Ministry of Education. All secondary school students are required to complete a community-based project that advances an important social cause. Students in GYLCE will participate in a four-week trip to Argentina to explore further the concepts and theories of youth leadership discussed in the course. They will also apply and see in practice the theories they explored during the spring semester through their direct involvement in service-learning projects in Argentina.…

The Exaflop/s: Why and How
Monday, November 29, 2010
Presenter: David Keyes, KAUST and Columbia University
Dr. Keyes lecture focused on Exaflops and the fourth paradigm, a movement towards meta-tags and improved classification of data. He began by showing what the increased accumulation of data has meant for the oil industry. They can now better solve an inverse problem or perform data assimilation, combine multiple complex models and quantify uncertainty. Through the GigaPOWERS Impact program, they went from a Mega-Cell to a Giga-Cell which helped find more oil patches. Oil companies are vast, with dozens of reservoirs “upstream” and many refineries and transportation systems “downstream”. Yet while the simulator is only a small piece of their puzzle and is already heavily taxing their computers. As a consequence, how should such computer resources be managed? Data is increasingly too complex for a self-contained, self-consistent theory.…

Mobile Learning
November 23, 2010
The use of mobile phones has greatly increased in recent years. Within just a few decades, mobile phone subscriptions expanded from 12.4 million in 1990 to an expected 4.6 billion by 2009. As more an more people switch to multimedia phones, individuals across the world will increasingly be able to access information through their mobile phone. Along with this, they may have access to augmented reality applications such as Google Goggles which provides the user with additional data about anything they are seeing with their phone, as well as many other augmented reality applications (link below). The possibilities for M-learning will likely improve as the processing power of mobile phones increases. Apart from learning, programs such as the Grameen Phone program have helped to increase connectivity and raise household income in Bangladesh. More and more universities in the United States are adding mobile apps to their range of educational output.…
