This document discusses pair programming, an agile software development technique where two programmers work together at one workstation. One programmer acts as the driver, writing code, while the other serves as the navigator and reviews each line of code. The roles are switched frequently. Benefits of pair programming include instant code reviews, knowledge sharing, and reduced training costs. Challenges include dependency on partners and difficulty with scheduling, noise levels, and skill imbalances between partners. Research shows pair programming can reduce assimilation time for new programmers and lower training efforts.

Seeing Problems Differently Results in Different Solutions
DTC Operator is one of my favorites for working with teams that feel stuck or just cannot move out of their own way to explore the system and problem from a different perspective. It allows people to work in extremes and through those extremes they see possibilities that felt silly or just wrong before.

Blind faith and best practices mike behnke @localpcguyMike Behnke
Abstract:
Stop using ==, you must use SASS, all your coding problems can be solved with Node.JS. So much advice and best practices, some of it from well-respected leaders in our web-dev community and much of it extremely dogmatic.
So how do you filter out the noise and find a happy middle ground? How do you go about finding the best practices you should follow in a practical world where things are messy?
This talk goes over some of the common front-end best practices and encourages engineers to not just blindly follow best practices, but understand the WHY behind them.

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.

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.

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.

I’LL NEVER GET CREDIT FOR DOING ANYTHING. I’LL HAVE TO
SHARE ALL THE RECOGNITION WITH MY PARTNER
THE ONLY TIME I EVER GET ANY REAL WORK DONE IS WHEN I’M
