Online Tech Conference 2021 - English Edition | Autumn

Description:
Code Engine is a serverless framework built to create modern, source-centric, containerized, and serverless apps and jobs. It is a very good and easy to use starting point for smaller containerized applications, since you can precisely control costs with scale to zero. Join Thomas as he explores containerized applications on IBM Cloud Code Engine, including - Deploy an existing Java microservices; Understand internal and external HTTP/HTTPS routing between the microservices; Use the Out-Of-The-Box monitoring for the example application; Use the Out-Of-The-Box logging for the application.

Description:
The addition of the hooks API to React was quite a major change. Before hooks most components had to be class based. Now, with hooks, these are often much simpler functional components. Hooks can be really simple to use. Almost deceptively simple. Because there are still plenty of ways you can mess up with hooks. And it often turns out there are many ways where you can improve your components by a better understanding of how each React hook can be used. Join me with your laptop in this interactive workshop. You will learn all about the pros and cons of the various hooks.

Description:
Building GraphQL API starts with the type-definition declaring the entities and operations of the API. But what then? Usually you'd go ahead and implement resolver by resolver manually to power your API. With neo4j/graphql all that's taken care of and you can focus on your API, top- and field-level queries and mutations are generated and can be secured with directives. In this workshop you'll learn all you need to build your own APIs quickly and effectively.

Description:
Convolutional Neural Networks is a well known method to handle euclidean data structures like image pixels, texts, time series, or even point clouds. However in real world, we are also surrounded by the non-euclidean data structure like graphs (e.g. social networks) and a machine learning method to handle this type of data is known as Graph Neural Networks. Therefore, in this 120 minutes workshop we will deep dive into an introduction study of Graph Machine Learning and its Applications in various domains followed by an interactive Hands-On-Session with a real world case study.

Description:
In this workshop, Rainer and Gustavo will present a product management concept called "The Value Engine". Learn in this workshop how to create an experimentation culture where truly empowered product teams contribute to the company’s strategy. Additionally, find out how to make it easier for leaders to lead with context, avoid micromanagement and create coaching opportunities. We all want to create value fast at scale – getting there is difficult but not impossible.

Description:
The broad adoption of container technology mostly driven by the rise of Docker and Kubernetes has changed the skill expectation towards developers. It is not only required any more to be knowledgeable about the programming language, framework and respective build process. The step of how to containerize the workload has become a standard. The ecosystem provides a wide range of options to approach container build like Dockerfiles, Buildpacks, Jib, ko, source2image and more. The talk will help for guiding through this ecosystem, as well as creating awareness about projects to perform this task.

Description:
It is no secret that the tech industry is suffering a diversity crisis. Despite initiatives to diversify, technology is still perceived as a predominantly white, male, middle-class industry. But this wasn't always the case - in 1943, computing was dominated by women. What happened? Join Antonia Forster, XR Technical Specialist, for a data-driven exploration of the gender gap:- how it affects your bottom line, how AI and machine-learning can reinforce bias, and the powerful evidence-based strategies you can implement to "close the gap".

Description:
Monoliths, microservices, containers, AWS lambdas (functions), and serverless computing--what is the right architecture for the job? Which use cases are best suited for on-premise deployments, and which applications must be deployed to the cloud? Are Java frameworks even relevant? There is not enough time to code in this short but interactive talk, so I will spend some time in the AWS console and explain the concepts on a whiteboard. Your questions are highly welcome.

Description:
For many years now, stateless-serverful has been the go-to pattern for building backend services. This pattern is well understood and supported by mature, powerful toolsets. While we have continually improved and fine-tuned stateless-serverful, we are always looking for something better, something different that may significantly improve how we build and run our systems. Often, a better way to do things is to take things in an alternate direction. In this case, replace stateless with stateful, replace serverfull with serverless. So what is stateful-serverless? Well, that is what we will cover

Description:
What are the essential first steps, and what should you focus on at the beginning? Of course, this raises the question of suitable methodologies and tools. At the same time, the strategic orientation of the company must be included in this security strategy. We have also learned in the recent past that attacks like the “Solarwinds Hack” are becoming more and more sophisticated and that the attackers now focus on the entire value chain. What tools are there, and where should they be used? How can I start tomorrow to prepare myself for the future against the challenges of cyber attacks?

Description:
We’ve been using Apache Druid for over 5 years, to provide customers with real-time analytics tools for various use-cases, including in-flight analytics, reporting and building target audiences. The common challenge of these use-cases is counting distinct elements in real-time at scale, and we will show why Druid is a great tool for that. In this talk, we will also share some of the best practices and tips we’ve gathered over the years. We will cover the following topics: Data modeling Ingestion Retention and deletion Query optimization

Description:
Frontend tests have been evolving at a much faster speed than the backend counterpart. The evolution happens to solve a number of pain points in frontend development. After working as a full-stack developer and seeing the evolution of tests on the frontend, I tried to apply the test trophy principle to backend tests. I will share why I did that, what the results are, and whether or not the test trophy is a good testing strategy for backend systems.

Description:
When IPv4 was devised, the designers went for a 32-bit address space, resulting in a maximum of 4,294,967,296 (2^32) unique IPs. But soon after that, it was clear that it was not even close to being enough. The workaround was NATs: devices that map a single public IP to multiple private IPs. NATs, though, created a new problem, as each NAT device maps IPs and ports in its own way, making it difficult to establish a peer-to-peer connection with devices behind a NAT. Several solutions have been put in place. This talk analyzes them and proposes a new library to simplify NAT hole punching.

Description:
With the shift to using Cloud services and k8s, developers suddenly have more design choices on how to run their applications. But more choices bring more bug possibilities. In this talk, I will share how the choice of k8s controller can hide software design choice bugs, told as a war story of migrating from a k8s Cronjob to a k8s Deployment and cronjob in code.

Description:
Agile seems to be everywhere and all the time. However, it appears not to be easy to get Agile going. Too many people struggle about getting the benefits Agile seems to promiss. Arie will take you on a journey how to involve business and take them into the responsibility to create business value together.

Description:
The inspirational session Focus ON/OFF is a fun and approachable way to understand the importance of focus. In interaction with the participants, we discuss recent insights and research on concentration and attention and, more importantly, the challenges in this area. The participant is introduced to the flow curve and how focus works. The topics from the bestseller Focus ON/OFF are briefly discussed. What is covered: How do concentration, attention, and stress work on a neurological level? Optimizing work & private life balance The difference between stress and work pressure

Description:
What is the best way to maintain the state of your application? The BLoC library offers a quick and easy way to manage our application state! In this talk we will discover how to use the BLoC Library, how it works under the hoods and what are the essentials steps to ensure that your state stays coherent with your BLoC State!

Description:
Developing an Alexa skill can be a lot of fun, but nobody likes to find negative comments and reviews in order to begin to identify and correct bugs. Skills developers use tests and automation to minimize these risks. In this talk, I will talk about how to test your Alexa skill thanks to the Alexa Skill Kit and its API. At the same time, I will explain how to automate the daily workflow of a skill, from commit to deployment using Open Source tools such as GitHub Actions, Codecov, Bespoken among others.

Description:
In the last decade many different types of neural networks have been developed. They showed us the amazing power and opportunities of machine learning. On the other hand the whole training process is not that efficient and costs a lot of energy. With that in mind we do know that neural networks are sort of based on the way humans learn. Except that the human brain is much more energy efficient. Could we achieve that same energy-efficient level in artificial neural networks? The answer is yes! I will show you what is often called the third generation neural networks: Spiking Neural Networks.

Description:
You might have heard about Headless CMS. This new type of content platform gives us some benefits compared to a Monolithic CMS. We will talk about the key features of any Headless CMS and how we can integrate a headless platform into our React applications. We will focus on Storyblok, a headless CMS that offers a real-time Visual Editor, a great feature for developers and content creators.

Description:
What if we could stop worrying about XSS vulnerabilities once and for all? What if we could just build our apps without having to think about the user content trying to execute malicious code on our website stealing our customers' payment data or even stealing access to some admin areas and potentially delivering even more damage? Well, Content Security Policy can provide us with that. We'll take a look at what it is, at its stable features, experimental features and examples of what it can look like on a large website.

Description:
Neurotechnology is the use of technological tools to understand more about the brain and enable a direct connection with the nervous system. Research in this space is not new, however, its accessibility to JavaScript developers is. Over the past few years, brain sensors have become available to the public, with tooling that makes it possible for web developers to experiment building brain-controlled interfaces. As this technology is evolving and unlocking new opportunities, let’s look into one of the latest devices available, how it works, the possibilities it opens up,, and how to get star

Description:
Wait! Not so fast - Stop scrolling and hang out with me for a while. When crafted with intent, scroll-triggered animations can add polish to a site, and make online storytelling feel more immersive, but they can be easily misused or overused. Let’s take a look at scroll-based animation together. We'll dig into the Intersection Observer API, the upcoming CSS Scroll-linked animations spec, and GreenSock's ScrollTrigger – but more importantly, how to create responsible animations that evoke delight rather than frustration.

Description:
The Fourth Industrial Revolution or Industry 4.0 has begun to connect everything to everything. The Internet of Things(IoT), machine-to-machine transmission, bots, AI-driven bots, and robots will take transportation to another level. As a result, the world is becoming a fully connected dense network. Developers will have to adapt to this new era and its challenges. The presentation will go through the new paradigm of Industry 4.0 AI developers. AutoML, APIs, online services, and Cloud AI are all disrupting development jobs. We will explore Industry 4.0 AI development examples.

Description:
When I saw how dense the European Covid Greep Pass QR code is, I got immediately curious: "WOW, there must be a lot of interesting data in here". So, I started to dig deeper and I found that there's really a great wealth of interesting encoding and verification technologies being used in it! In this talk, I will share what I learned! We will go on a journey where we will explore Base54 encoding, COSE tokens, CBOR serialization, elliptic curve crypto, and much more! Finally, I will also show you how to write a decoder for Green Pass certificates in the most hyped language ever: Rust!

Description:
Many of us have built applications for traditional data structures (like relational database tables), but is it different for graph data stores? In this session, we will cover a brief intro to graphs and build a typical Java application for a graph database. We will interact with the graph data from the application, and explore some deployment possibilities. Join us to see how to amplify the power of connected data with applications!

Description:
Serverless computing transactions are a combination of owned code and managed services. Applying distributed tracing on your own code through instrumentation is relatively simple. The challenge lays with the managed service, how to trace a full transaction across services like queues, streams, and databases. We'll discuss: The technical challenges gaining observability with managed services Methods to build the full trail of transactions across managed services Ideas on how to obtain observability in a highly async distributed world Drill down to managed services examples

Description:
Your project has reached that stage when it’s a good idea to post binaries, but new questions appear such as where should they be posted? How do make it easier for users to install and discover your binaries? Where should releases be announced? Most importantly, can answers to these question be automated? Enter JReleaser, a tool that provides answers to these questions and more. JReleaser may be used to create GiHub/GitLab/Gitea releases and publish binaries that can be consumed from different distribution channels such as Homebrew, Snap, Scoop, and more.

Description:
It’s easy these days to fall into the trap of starting to design your whole application with a microservices architecture…. Because, you know, that’s what everyone is doing. aren't they? But, are we considering the microservices architecture as a goal, or as a means to a purpose? In this talk we will go back to the basics, and see how DDD, CQRS and EventSourcing practices drive our application design and evolution in such a way that we will start with a monolith but we will have the ability to scale into microservices more or less easily when (and more importantly: if) we need to.

Description:
This speech describes a success story of development process in my current project from QA point of view with emphasis on automation testing and technologies used to put our goals into effect. This is not supposed to be a tech story but more like a retrospective of the last 2 years since I joined the project. I'm going to tell you how the test automation process in the project was established through these years and what we've finally achieved.

Description:
Recent development trends have enabled the reduction of application scope by favoring modular and distributed architectures. From monolith to microservices then to micro frontends, applications have become more specialized and the final composition more complex. The use of a platform then becomes a critical aid to enable the full application development life cycle by leveraging the ability to distribute and share application components. What if the developer of tomorrow has to become a “contributing developer”? What if the future is composable?

Description:
At a time where almost every experience has a digital component the role of designers in shaping behaviours and opinions becomes more and more important. While designing digital experiences, we are facing difficult ethical questions - privacy, algorithmic bias, technology addiction, harassment. How can we best deal with these questions? The key is to focus on the "most vulnerable person" that will use the product. if you design with people in mind that might be hurt or negatively impacted by it you'll end up designing a better experience for everyone.

Description:
Got a robot dog you want to remote control? You came to the right place. Want to monitor your heart rate in real time? Ditto. Bluetooth® technology is sophisticated, versatile and secure and like all serious technologies, there’s a learning curve. If you’re short of time and just want to get something working then this is the session for you. This talk will emphasise the practical rather than the theoretical and help you get started developing applications that use Bluetooth technology for controlling or monitoring other devices. No pain. Lots of gain.

Description:
Do our neighbours know if we use contraception? No! But we can be sure that a lot of companies know because we have used certain apps like period trackers. One thing is clear: data privacy has long been a thing of the past and as we both aren't Tech-People, we have no chance to protect our privacy by our own. What can we do to regain control of our data, to restrengthen Europe’s data capital and to profit from our own data? Our approach building a decentralized data economy from Europe for Europeans! That won't work without Developers taking their responsibility protecting users like us.

Description:
Developers like to code. With traditional support, developers fix bugs & deal with customer issues more often than actually doing the work they love. This session will discuss what makes DevSuccess different from traditional support, why it’s crucial within R&D teams, and how to build a successful DS team to help your dev users thrive. Utilizing a developer focused customer success allows for a frictionless connection between Product & Engineers and creates customer focused focal points for R&D teams. When your R&D is focused on developing with a customer point of view, the whole company wins.

Description:
As an early Machine Learning practitioner working with a small number of models it was easy to think that wrapping a model in an API was all that was needed. Since then, having worked with customers that deploy thousands of models at scale, I’ve realised quite how naive that worldview was. The road to MLOps best practice is long, hard and poorly defined… In this talk I’ll cover the mistakes I’ve made, what I’ve learned along the way, and how DevOps principles are bleeding over into the field of ML.

Description:
Beer brewing can be fun, but combining brewing with IoT device hacking is even funner. It is possible to connect and collect data about almost anything, including the fermentation process inside a closed fermenter using open source technologies. In this presentation, the speaker will introduce basic concepts of IoT devices, how to collect the data efficiently and how to use JavaScript to extract and manipulate that same data into a React front-end. And if you’re new to beer brewing, don’t worry; you will also learn a thing or two about that as well!

Description:
GraphQL exposes application data as a graph which can introduce challenges if your backend isn't graph-ready (think slow JOINs as a result of nested GraphQL queries and the dreaded n+1 query problem). The Neo4j GraphQL library enables developers to build GraphQL APIs backed by a native graph database using only GraphQL type definitions. In this talk we'll see how to build a GraphQL API without writing any resolvers, add custom logic, and deploy to the cloud.

Description:
Wix has a huge scale of traffic. more than 500 billion HTTP requests and more than 1.5 billion Kafka business events per day served by 2000 microservices. A cache will reduce latency and needed scale, by avoiding the need of a costly query to a DB, a HTTP request to a Wix servicer, or a 3rd-party service while increasing reliability. Patterns you will learn about: Locally/S3 Persisted Configuration Data Cache HTTP Reverse Proxy Caching (Dynamo)DB+CDC based 2nd level Cache

Description:
In an ecosystem with many microservices and complex business processes, we frequently have to manage transactions that span different applications. The Saga pattern is a structured way to manage this type of processes, allowing us to automate commits and rollbacks on transactions spanning different microservices.

Description:
No cloud skills, no career. As we accelerate towards the future of everything online, cloud skills will be ever more in demand. Not just for engineers, but for your whole team and the rest of the office. But where to start learning? AWS offers nearly 200 services, Azure nearly 275. And then we have stuff like Docker, k8s, serverless, dbs, ML, IoT, cost optimization, security. It‘s all quite overwhelming. Let Piet help by showing you the learning paths you can follow towards cloud competence, plus the serious game and social learning application his company developed to become cloud natives.

Description:
Data science and machine learning are helping to drive business decisions and generate income and insights for organizations across a spectrum of industries, from oil and gas to financial services, and many in between. However, developing and deploying ML workflows can be challenging. In this codelab, you’ll learn an easy way to incorporate data science and AI/ML into an OpenShift development workflow. You will use an object detection model by using Jupyter Notebooks and TensorFlow to explore a pre-trained object detection model, and serve the model in a REST API as a Flask App.

Description:
A clean architecture for greenfield projects is relatively easy. However, we usually work on legacy systems and an architecture must adapt in an evolutionary manner - otherwise it will also become legacy very quickly. This talk shows different approaches how to improve legacy systems with domain-driven design. It focuses on different techniques for introducing bounded contexts and assessing where improvements are needed. This way, Domain-driven Design becomes possible where it is needed most - in existing, hard to maintain systems that are often very successful and critical for the business.

Description:
In the distributed computing world, we learned to separate the concerns and distribute the tasks across several different micro services. This approach is good for scalability purposes but opens a great dilemma in the context of versioning. In fact the inter-communication needed among micro-services is difficult to maintain every time there is some change in the respective models. In this talk we will take a new approach that is based on semantical metadata and .NET code-generation techniques that let us free to evolve the models. The result is to automatically the domain specific boilerplate

Description:
What if you could increase safety for a large group of people in The Netherlands? We are talking about cyclists! The normal ones. Preferably the ones that need an extra set of eyes. You know, the people who are the same age as your parents. Who thought it would be fun and good for their health to get a new bike... the ones that go like hell… To help them being more safe our team created a system using the opencv ai kit oak-d camera(our Kinect) to alert them on time for oncoming traffic, potholes and other dangers. How? Come to this talk and take this ride with me.

Description:
In this session learn how running a Distributed Database on Kubernetes allows you to: Scale your database effortlessly - Each instance of the database is the same, allowing developers to spin up new instances without manual work Easily survive pod failures - A database that replicates data and automates placement across pods so users can survive any failure and avoid downtime without any impact to production applications. Automate basic configurations, deploy secure database clusters, and upgrade databases without any application downtime.

Description:
Remember Atomic Design? It's been a while since we started talking about Design Systems. They're supposed to solve our interfaces inconsistencies issues, as a single source of truth. But do you know well how to build and use them, from a developer perspective? Here's your ultimate guide to Design Systems, for Devs! From the fundamentals of Design Tokens definition, to how to build advanced versatile layouts.

Description:
In this session we will see how to do transfer learning over a state-of-the-art pre-trained model like RoBERTa to achieve our own goal in Named Entity Recognition with our own DataSet. We will take and label new data to finally feed the network trying to achieve transfer learning. Then we will make use of the new fine tuned weights and use FastAPI to deploy our new fine tuned model to kubernetes to make inference. We will be playing with Spacy, huggingface, pytorch, python, FastAPI, Azure Kubernetes Services, CUDA hardware and terraform :)

Description:
GridSearch be really distracting. It sounds like a good idea, but does that optimal statistic you found really reflect reality? In this talk I will share some anecdotes of state-of-the-art models, as well as benchmarking in general, that will hopefully make you rethink your methodology. I will zoom in on benchmarks in the realm of NLP, but the lessons should apply in any subfield of ML.

Description:
We will take the audience on the musical journey of an artificial intelligence learning how to reinvent musical instruments. Starting with digitally interpreting sounds, mimicing instruments using feed-forward neural nets, and ending with a metamorphosis of instruments using Generative Adversarial Networks. We want to explore the unexplored, travel the rimworld of sound space! A generating network is inventing sounds, trying to please a second network, which is trained to recognize known instruments. As we tweak the settings of the generative network, we morph to a new paradigm of sounds.
