Entity Framework and Domain Driven DesignJulie Lerman
Given at Oredev 2013 (Nov 2013 in Malmo Sweden). This presentaiton is about the intersection of Entity Framework (EF ) and Domain Driven Design (DDD) and gives pointers about *not* worrying about EF when implementing your domain in code and what you can expect when it's time to implement the persistence layer. There is a video of me giving this presentation on Vimeo at http://vimeo.com/78893724
ADO.NET Architecture
Data processing has traditionally relied primarily on a connection-based, two-tier model. As data
processing increasingly uses multi-tier architectures, programmers are switching to a
disconnected approach to provide better scalability for their applications.

Facing Backwards While Stumbling Forwards: The Future of Teaching Web Develop...Randy Connolly
Talk given at SIGCSE'19. Web development continues to grow as an essential skill and knowledge area for employed computer science graduates. Yet within the ACM CS2013 curriculum recommendation and within computing education research in general, web development has been shrinking or even disappearing all together. This paper uses an informal systematic literature review methodology to answer three research questions: what approaches are being advocated in existing web development education research, what are current trends in industry practice, and how should web development be taught in light of these current trends. Results showed a significant mismatch between the type of web development typically taught in higher education settings in comparison to web development in industry practice. Consequences for the pedagogy of web development courses, computer science curriculum in general, and for computing education research are also discussed.

Every year at our new student orientation, I used to give this talk to our first year students. Instead of telling them what they should do to achieve success, we thought it would be more effective and humourous to tell them instead how best to fail your courses. This was the last version of this talk from 2017.
Red Fish Blue Fish: Reexamining Student Understanding of the Computing Discip...Randy Connolly
This 2016 presentation (for a paper) updates the findings of a multi-year study that is surveying major and non-major students’ understanding of the different computing disciplines. This study is a continuation of work first presented by Uzoka et al in 2013, which in turn was an expansion of work originally conducted by Courte and Bishop-Clark from 2009. In the current study, data was collected from 668 students from four universities from three different countries. Results show that students in general were able to correctly match computing tasks with specific disciplines, but were not as certain as the faculty about the degree of fit. Differences in accuracy between student groups were, however, discovered. Software engineering and computer science students had statistically significant lower accuracy scores than students from other computing disciplines. Consequences and recommendations for advising and career counselling are discussed.
Constructing and revising a web development textbookRandy Connolly
A Pecha Kucha for WWW2016 in Montreal. Web development is widely considered to be a difficult topic to teach successfully within post-secondary computing programs. One reason for this difficulty is the large number of shifting technologies that need to be taught along with the conceptual complexity that needs to be mastered by both student and professor. Another challenge is helping students see the scope of web development, and their role in an era where the web is a part of everyday human affairs. This presentation describes our 2014 textbook and our plans for a second edition revision (which will be published in early 2017).
Computing is Not a Rock Band: Student Understanding of the Computing DisciplinesRandy Connolly
This presentation reports the initial findings of a multi-year study that is surveying major and non-major students’ understanding of the different computing disciplines. This study is based on work originally conducted by Courte and Bishop-Clark from 2009, but which uses a broadened study instrument that provided additional forms of analysis. Data was collected from 199 students from a single institution who were computer science, information systems/information technology and non-major students taking a variety of introductory computing courses. Results show that undergraduate computing students are more likely to rate tasks as being better fits to computer disciplines than are their non-major (NM) peers. Uncertainty among respondents did play a large role in the results and is discussed alongside implications for teaching and further research.
Citizenship: How do leaders in universities think about and experience citize...Randy Connolly
This presentation explores the concept of citizenship based on the experience of student leaders from a mid-sized university in western Canada. Five student leaders participated in semi-structured individual interviews to explore their experience with, and understanding of, citizenship. Interviews concentrated on personal view points and definitions of citizenship, explored whether or not there are “good” and “great” citizens, and the role universities play in fostering strong citizenship amongst its student body. The measurement of citizenship and opportunities to foster citizenship were also explored. Qualitative content analysis revealed five themes, including political participation, social citizenship/solidarity, engagement, transformative action and autonomy. Citizenship, while highly valued by this population, also appears to be impossible to measure. If post-secondary institutions are aiming to create better citizens, more work needs to be done to create a common understanding of the intended outcome. Based on these findings, a new potential model of citizenship is proposed, in line with the work of Dalton and others who emphasize a shift towards personal involvement over traditional political engagement. Further, these results suggest that students could benefit from understanding themselves as political agents, capable of inculcating change within the university context and beyond.

A longitudinal examination of SIGITE conference submission dataRandy Connolly
Presents our examination of submission data for the SIGITE conference between the years 2007-2012. SIGITE is an ACM computing conference on IT education. The presentation describes which external factors and which internal characteristics of the submissions are related to eventual reviewer ratings. Ramifications of the findings for future authors and conference organizers are also discussed. If you want to read the full paper, visit http://dl.acm.org/citation.cfm?id=2656450.2656465
This presentation is based on the 16th chapter of our textbook Fundamentals of Web Development. The book is published by Addison-Wesley. It can be purchased via http://www.amazon.com/Fundamentals-Web-Development-Randy-Connolly/dp/0133407152.
This book is intended to be used as a textbook on web development suitable for intermediate to upper-level computing students. It may also be of interest to a non-student reader wanting a single book that encompasses the entire breadth of contemporary web development.
This book will be the first in what will hopefully be a textbook series. Each book in the series will have the same topics and coverage but each will use a different web development environment. The first book in the series will use PHP.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
