User Testing in the Invisible World of APIsPronovix
How you name, design, and structure your APIs all has a huge impact on usability. What you request and what you return in any given call can change your developer’s experience, and so just as we test usability in an app on a phone, we need to test usability of our products. In this session, we’ll cover a few different techniques and strategies you can use to run user testing on your APIs. Learn how to prototype and get quick answers to little questions, as well as how to conduct some more extensive studies to really target future features and major fixes for your product.
Building Event Driven Architectures with Kafka and Cloud Events (Dan Rosanova...confluent
Apache Kafka is changing the way we build scalable and highly available software systems. Providing a simplified path to eventual consistency and event sourcing Kafka gives us the platform to make these patterns a reality for a much broader segment of applications and customers than was possible in the past. Cloud Events is an interoperable specification for eventing that is part of the CNCF. This session will combine open source and open standards to show you how you can build highly reliable application that scale linearly, provide interoperability and are easily extensible leveraging both push and pull semantics. Concrete real world examples will be shown of how Kafka makes event sourcing more approachable and how streams and events complement each other including the difference between business events and technical events.
The UX of DX: User Testing in the Invisible World of APIsPronovix
As anyone who has tried to call certain endpoints knows, being RESTful isn’t the only requirement to making your API product easy to use. Developers are people too and as DX experts we owe them the same UX testing we do with our front-end products.
AWS Step Functions is a new, fully-managed service that makes it easy to coordinate the components of distributed applications and microservices using visual workflows. Step Functions is a reliable way to connect and step through a series of AWS Lambda functions so that you can build and run multi-step applications in a matter of minutes. This session shows how to use AWS Step Functions to create, run, and debug cloud state machines to execute parallel, sequential, and branching steps of your application, with automatic catch and retry conditions. We share how customers are using AWS Step Functions to reliably scale multi-step applications such as order processing, report generation, and data transformation–all without managing any infrastructure.

I hope this short presentation can give you some insights about the way you're using Scrum or clarify your understanding about it. If you and your team have decided to use only a bit of Scrum, it's absolutely fine. However, make sure people understand that the "thing" they are using is not Scrum. Don't put your blame on Scrum when you're not using this framework as it was created for.
This presentation is a brief introduction to Scrum Master role as part of Scrum framework. It also highlights the main Scrum Master rights and responsibilities. That's not all you should know about this role as being Scrum Master in the real world might not be as simple as it looks like.

Monografia sobre crowdsourcing + crowd testing + processo de teste de softwareMoisés Armani Ramírez
Esta é a monografia que deu origem ao meu artigo estendido intitulado "CROWD TESTING: O PODER DA MULTIDÃO EM PROL DA QUALIDADE DE SOFTWARE".
Aqui é possível ver a referência mais abrangente sobre Crowdsourcing e Processo de Teste de Software Tradicional.
CROWD TESTING: O PODER DA MULTIDÃO EM PROL DA QUALIDADE DE SOFTWAREMoisés Armani Ramírez
Controlar a qualidade de um software é uma atividade que exige tempo, esforço e conhecimento técnico sobre teste de software e sobre o sistema a ser testado. Não há garantia de que um software esteja 100% livre de defeitos e quanto mais se tentar aproximar desse percentual, maiores serão os custos do projeto. Diversas metodologias tentam reduzir os custos em testes sem impactar na qualidade do sistema. Contudo, existe um antigo e profundo impasse: esforço necessário de teste versus tempo disponível para testes. Este trabalho aborda o conceito de crowd testing e apresenta como uma multidão pode contribuir na qualidade de software a fim de amenizar o impasse entre esforço e tempo. Como não há trabalhos científicos que abordem o assunto, a proposta deste trabalho foi utilizar os conceitos de crowdsourcing e do processo de teste de software para, então, identificar como e onde o crowd testing pode ser utilizado no controle da qualidade de software. Trata-se de uma pesquisa exploratória baseada em bibliografias cientificas e documentais para a definição de crowd testing.

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.
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.

Cycle Time
"Cycle Time is the amount of time a team/
person spends actually working on a work item
up until it is ready for delivery". (businessmap)
"Is a metric that measures how long it takes for
an item to move from the “in-progress” column
to the “done” column". (Kanban Tool)
Throughput
"The number of work items exiting from the
system or a given part of it; measured in work
items delivered per time period. Throughput is
often referred to as delivery rate". (Kanban
University)
"It’s the number of completed cards per day,
week, or a given iteration time". (Kanban Tool)
