Q/A

API are not just an integration technology performing some complicated actions in the background. Even though it doesn’t do something you can touch and feel, it is a product. API have capabilities, features, and instructions. Things that differentiate it, and bring value. They have needs that are critical to its success – just like any other product. The success of your Product(API) is determined by the pace developers are adopting it. If the word “API” is in your landscape as the answer to growing your organization’s profitability, this session is dedicated to helping you. In this talk you’ll understand the importance for bringing Developer Experience to the start of your product development, and bringing developers to the front of decision making. We’ll highlight the “Dos and Don’ts” of adopting a successful API strategy at large scale Enterprises. Finally, we’ll review successful ways of talking about APIs as Products.

Candy Crush Saga is one of the biggest mobile games today with more than 1000 levels of difficulty - and users continue to ask for more. When building new content, it is extremely important to make sure that the level of difficulty is balanced and that the user does not experience crashes or problems through some unforeseen level of play. Alexander Andelkovic shows you how King is training artificial intelligence (AI) programs (bots) to test its games by mimicking human interactions. Join Alex as he discusses how King is taking testing to the next level by employing Monte Carlo Tree Search, automatic heuristic construction, and NeuroEvolution of Augmenting Topologies (NEAT) to train bots to test and evaluate difficulty levels. He discusses ways to extend and use AI bots to predict game success rates and conduct automatic performance testing. Alex explains how this AI approach can be generalized to test other applications. Learn how AI can help you with testing that's getting very difficult to master with traditional testing techniques.

Cover Your Apps While Still Using npm

Tierney Cyren

In the front-end and Node.js ecosystems, we’ve had two extinction-level events: left-pad and pinkie-promise. These events were both caused by something simple - a module became temporarily unavailable. Something seemingly innocuous caused thousands of developers and businesses builds to break and installs to fail. They weren’t prepared, and many were eager to blame npm as the single point of failure of the entire JavaScript ecosystem. In reality, npm has made it dead-simple for developers and organizations to make sure their modules and highly available. The majority of the ecosystem isn’t aware of this, nor do they implement it effectively. In this talk, we’ll go over how the dependency tree works at a high level, how you can get bitten by it, and how you can cover your apps - both as developer and as a business.

Angular vs. React

OPITZ CONSULTING Deutschland

www.opitz-consulting.com How do Angular and React compare? Can we compare them at all? Actually, it's like comparing apples to oranges, but even so, we have to compare them. As it turns out, both frameworks are a nice example of co-evolution. They aren't as different as they used to be a few years ago. After showing the key concepts of both frameworks, our experts Dr. Marius Hofmeister and Stephan Rauh presented a small list of criteria helping to decide when to use which at iJS Conference in Munich on 25/10/17.

Allon Mureinik

Being a maintainer, or even a notable contributor in an open source project is a damn hard job. Not only are you expected to tackle the hardest programming tasks, but suddenly you're also expected to do all these "softer" things - review other people's work, provide feedback, ramp up other contributors, etc. In this talk from DevConf.us 2018, I've shown how your gut instinct as an engineer - to automate everything - can actually work here too (at least to a certain degree), and take a lot of the load off your shoulders.

Microservices architectures make applications easier to scale and faster to develop. But building containerized microservices across multiple teams means you need well-defined, methodologies for software design and implementation. In this webinar we’ll discuss best practices for building containerized microservices on AWS, and how traditional software design patterns evolve in the context of containers. We will deep-dive into Martin Fowler’s principles of microservices and map them to the twelve-factor app pattern and real-life considerations. Finally, we'll show you an example of building and running a containerized microservices app using AWS Fargate.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan 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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf

Paige Cruz

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack. While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack. I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate Impact of Software Testing at Nordic Testing Days

Kari Kakkonen

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
