AuditoriumFriday 10.Nov
A live demo and presentation of Cycleops about the deployment software landscape
The work of delivering software products to end customers is the core business of an increasing number of companies around the world. At the same time, the process of developing software applications calls for a larger set of skills from the engineering teams. This skillset is missing from the market. That's why many companies are actively searching for DevOps engineers to hire, but having trouble finding them.
Automation is the response of the engineers to the need for delivering more features to a wider audience, while eliminating human error and increasing quality and efficiency. DevOps is the culture of collaboration between teams involved in different stages of the software development lifecycle. However, even in the simplest of cases, DevOps processes still claim the precious time of DevOps engineers.
Cycleops offers the solution to automate deployments in a simple, fast, and accessible manner that align with the current working environment of software vendors. Today, we will demonstrate how to use Cycleops to deploy your Docker-based applications to bare metal servers. This will enable you to reduce costs while benefiting from the automation capabilities you would expect from a cloud platform. Additionally, we will provide a comparison of various deployment solutions in the industry to help you understand how Cycleops fits in the market.

FoyerNOPASSWD: Building a Passwordless Cloud Infrastructure
AuditoriumFriday 10.Nov
THEME: DevOps, CYBERSECURITY
Passwordless systems are fast becoming a reality as many of the big players (Microsoft, Google, Okta, AWS Cognito) implement support for FIDO2 and related technologies.
Although developers are making great progress in using these technologies to implement new passwordless architectures for the users of their products, we are years behind in doing the same for our own internal infrastructure. Tokens, passwords, and other secrets that are shared internally among developers are a major security risk, yet are extremely common among companies of all sizes.
This talk gives an overview of the current situation and associated security risks, a review of FIDO and FIDO2 standards, the options we have to improve our designs, and a case study of a sample passwordless infrastructure stack. We'll also discuss things to look for and avoid when selecting vendors and development tools to greatly improve security posture.
Learn how your team, regardless of size, can put all of the pieces together to implement a more secure, passwordless infrastructure.

AI Capabilities, Ethics, Limitations, and Potential
AuditoriumFriday 10.Nov
THEME: AI
Artificial intelligence (AI) is rapidly transforming our world, from the way we work and communicate to the way we make decisions and interact with each other.
As AI systems become more advanced, they raise complex philosophical questions about the nature of intelligence, consciousness, and ethics.
In this talk, we will explore these questions from a scientific and philosophical perspective, examining the latest research on deep artificial neural networks and their implications for our understanding of cognition, ethics, and safety.

FoyerIn AI We Need To Trust; Not There Yet
AuditoriumFriday 10.Nov
THEME: AI
Back in 2018 in his book “21 lessons for the 21st Century”, historian Yuval Harari emphatically noted that “Already today, ‘truth’ is defined by the top results of the Google search.”. The recent developments and disruptions caused by foundational AI models (to put it simplistically) such as ChatGPT denote the gravity and criticality of integrating the AI technology in every aspect of our lives. However, how feasible is it to trust AI systems? In 2022, journalist Karen Hao’s article about Facebook’s AI systems, reveals an interesting truth; tech organizations may not be in control of their AI systems. What seems to be even more worrisome, is that tech organizations may not want to be in control of their AI if this impedes their growth, or profits (or both).
AI systems tend to be highly dependent on data, so their error-proneness and potential impact rely on how they treat those data. If we consider that data are socially constructed or simply put, data reflect how we, humans, live, then this means essentially two things:
- AI systems need to be designed in a way that ensures they can be trusted,
- The organizations that own and operate AI systems should be mature enough for governing them responsibly.
All these beg several questions such as: What are the best practices when evaluating how an organization governs an AI system? What are the upcoming regulations dictating how we can audit AI systems? What are the essential aspects of an AI system that we as engineers need to test? How is it possible for an organization to find a balance between building Trustworthy AI versus optimizing for efficiency and for maximizing their business profits?
In his speech, Yiannis Kanellopoulos will elaborate on the above mentioned questions in a practical way and provide real-life examples on how an AI system can be tested in terms of its Performance, Fairness, Accountability, Transparency and Safety/Security.

AuditoriumFriday 10.Nov
THEME: GreenTech
Do you know that the greenhouse gas emissions from software applications surpassed those of the aviation industry in 2021? As our reliance on technology continues to grow worldwide, so does the environmental impact of software applications. But as software developers, we have the power to make a positive impact in the fight against climate change.
This session revisits the established development practices, providing practical guidelines that developers and architects can follow to measure and reduce the environmental footprint of software applications.
The focus is on practices requiring a minimal development effort, still providing the maximum savings in carbon emissions. At the same time, most of these practices will help reduce the costs of your cloud applications because they minimize the consumed resources (CPU, memory, storage, network). It is assumed you are involved in building software applications and aspire to help prevent climate change.

FoyerQuantum technologies in European Space Agency
AuditoriumFriday 10.Nov
THEME: Cybersecurity, Quantum Tech
Quantum technologies use the quantum properties of physical objects (e.g. photons, atoms or more macroscopic objects) for both practical purposes and scientific experiments. In the last century, these effects have been mostly studied in academic settings, but recent years have seen an increasing development towards real-world applications.
In general, quantum technologies can enable measurements with higher precision (e.g. gravity & accelerations, time & frequency, electromagnetic fields, etc…), that are leading to new type of devices (quantum computer, quantum cryptography) or enable fundamental physics science experiments (e.g. exploring limits of quantum theory, quantum gravity).
In many of these applications, space plays an important role. Additionally, new concepts such as the rising performances of quantum computers, the quantum internet or quantum sensing devices offer many opportunities for being used either in space or being beneficial for the space industry in general. In this talk,
I am going to present the status of European Space Agency in view of space technologies and payloads in relation to satellite quantum optical communications and Cyber security.

#CybersecurityTight Genes: Intro to Genetic Algorithms
AuditoriumFriday 10.Nov
THEME: AI
"Yes, that's right, genetic, not generic. Genetic algorithms are shortcuts to ""evolve"" solutions to problems, similar to real-world biological evolution. They find a ""good enough"" solution more quickly than precise calculation or brute-forcing through all possible options. The randomness often reveals great solutions that humans probably would never have thought of, such as NASA's twisty ST5 spacecraft antenna, developed by a genetic algorithm in 2006!
This talk will explain the general concept, and then walk through a few examples, explaining terms and pointing out tradeoffs and nuances along the way. It will show creating genetic algorithms to solve two different problems, extracting a simple generic “evolver” from the code for those, and using that to supply the common parts for a third problem.
You will come away equipped with a powerful technique for solving problems in ways no human would probably ever think of directly!"

FoyerOur AI Models Are Only as Good as Our Data
AuditoriumSaturday 11.Nov
THEME: AI
The increasing prevalence of artificial intelligence (AI) applications, such as search engines, AI chatbots, social media content recommenders and image generation, are already impacting various aspects of our lives. People who possess an understanding of how AI functions will be better equipped to interact with the world and make informed decisions about utilizing and developing AI applications. Additionally, they will be capable of enhancing their critical thinking abilities, and will gain a deeper appreciation of how AI can be utilized to develop novel solutions to problems they may face.
This talk will be two-fold. In the first part, we will cut through the hype and clarify the definition of AI. Our discussion will revolve around the conventional computer programming approach, followed by an overview of how the machine learning example changes it. We will examine how models are trained in contrast to how programs are coded and highlight the essential role of data in this process. We will also explore how these models attempt to replicate the behavior of intelligent entities, by ""comprehending"" natural language and ""perceiving"" visual content to some extent.
The second part of the talk will focus on the challenges that may arise from data, including how AI applications can make mistakes due to poor data quality. Our examples will come from the language technology industry: language understanding and generation applications. Moreover, we will discuss the ethical and fairness considerations in developing responsible AI models. The talk will conclude by touching on the digital divide between languages and how it poses a threat to the survival of many of the world's 7000 spoken languages.
All in all, this talk aims to demystify and make AI more accessible to a wide audience, by clarifying its concepts and highlighting the importance of curated data in creating models that have real-world applications.

#cognitive, #dpeThe Quest for Evidence-Based Technical Debt Management
AuditoriumSaturday 11.Nov
THEME: Tech Leadership, SW Craftmanship
Technical debt is an established concept in the software industry. Developers know that "quick and dirty" will return and haunt you later.
The interest is the extra effort you must dedicate to future development because of previous shortcuts. However, awareness of code issues rarely leads to action, and the debt is not paid off – typically because implementing new features gets higher priority.
What if we could cast a light on the technical debt interest rates? In this talk, we will discuss the business impact of poor code quality. The findings originate from original research and our ongoing quest for evidence-based technical debt management.
You will leave the session with a new perspective on the costs of technical debt – ready to motivate the next refactoring campaign!
