In the end, we watch the interview with the Tibetan monastery monk taken in the Himalayas about his opinion on praying with the app.

About the talk

The fugu, or pufferfish, is a toxic, potentially lethal delicacy that, prepared correctly, is a culinary masterpiece.

The web platform is less deadly, but still requires careful preparation when incubating new features. Project Fugu is the Chrome team’s initiative to bring more power to the platform. Many of the experiments are trials or behind flags to ensure they are being prepared correctly.

In this session we’ll investigate the features that are coming out of the Fugu kitchen, have a taste of some that are nearly ready and take a peek into the future to see what’s in store for the future. By the end you’ll be equipped with the features to make your web application a masterpiece too.

About the talk

Some decades ago, IT auditors seemed to have a more predictable life. Of course there were challenges at the beginning, until methodologies, routines and procedures have been developed for the IT operational environment. But one can say the diversity of the IT landscape was changing with a bearable pace.

Now, we couldn’t say the same for the times we are living. Models and paradigms IT auditors have operated under for years, are undergoing a fundamental shift. Modern business environment, exponential increase of data volumes, emerging technologies leading to new IT, security & cyber security risks are bringing IT auditors to a new reality.

There is no doubt innovation is one of the answers.

The old mode of downloading and installing software (SqlServer, Mongo, Rabbit, even frameworks as Angular and .NET Core) will be soon of the past memory.
If you want to join the new wave, see how Docker can easy your work as a developer. I will present first an introduction to Docker and show some easy samples. Then I will show how to create, build, run, test (unit and integration) an application with Docker without installing frameworks and/or databases on my PC.

About the talk

Once upon a time, not so long ago (literally… it’s like a couple of weeks) a brave young soul was given the task to architect and incubate a project rewrite.
The king (an architect from the client) wanted to gather the troops and build a new, shiny palace, for his was old and deprecated (AngularJs 1.x).
The king has learned that there was this thing used in other kingdoms called microfrontends and instructed our hero to investigate and report back how this can be done.
After a while, our hero bravely returns to the king with his findings.
The king was pleased and instructed our hero to build a scale model of what he thinks would be appropriate for his majestic majesty.

Thus our hero has come from afar to tell the story of Microfrontends.

The way we develop apps in eMAG has been shaped by Black Friday, an event that we have been organizing for the past 9 years. In the first few years we approached Black Friday start-up style: it came into focus a few weeks before the actual event. Now, however, its impact on the eMAG site is the first question we ask ourselves before starting any development. In this presentation you are going to find out how, through heavy testing and cutting edge dev-ops tools, Black Friday has shaped eMAG into what it is today.

Fast and Efficient Java Microservices with GraalVMThis year we celebrate 25 years of Java, and its future is looking even more exciting with new opportunities becoming possible every day. One of them is creating Java microservices that offer fast startup and low memory footrint, perfect for cloud-native era, in addition to Java’s distinctive peak performance.In this session we’ll learn how to build Java microservices that start in milliseconds and have a low memory footprint. You can achieve those benefits by using GraalVM — a high-performance virtual machine, that can also compile Java code into native binaries. We’ll also explore ways to get started, take a look at various frameworks that support this capability, and how to make the best out of it for existing projects.

About the talk

Bluetooth acquired a new capability in 2019. It’s now possible with suitable hardware, to calculate the direction a Bluetooth signal is being transmitted from, using one of two methods known as Angle of Arrival (AoA) or Angle of Departure (AoD). From this, it’s possible to accurately determine the location of the receiving device to within a matter of centimetres rather than metres. Proximity applications like Point of Interest (PoI) information systems and the classic “key finder” are all set to get very accurate and much easier to use. Positioning systems such as Real Time Locating Systems (RTLS) and Way Finding will offer a level of precision, never before possible with Bluetooth.
Hear about this new Bluetooth feature, how it works and the uses it’s likely to be put to, in this session.

Progressive Web Apps (PWAs) enhance web applications and make them ready for the future. One of the most important features of PWAs is their offline capability, as it avoids connectivity issues and drastically improves the user experience. In this session we dive into the world of PWAs, looking at different caching strategies and modern tools to easily build progressive web apps. We will see a real world demo using the Angular framework and Cloud Firestore Database. Firestore is a cloud database solution that enables the offline capability that we are looking for.

About the talk

Anything that’s designed for good will eventually be used for evil, and that is definitely true of bots. Bad-bots dominate the internet. It’s hard to get through any news cycle today without them being mentioned. They spread spam, propagate fake news, or create fake profiles and content on social media sites—often to influence public opinion, spark social unrest, or tamper with elections.

No matter where you look, it seems that the dark web is winning. Good news isn’t interesting. No-one clicks on happy stories. In so many ways, it’s easy for the tech to be used more effectively for bad than for good.

Join Michelle Sandford – Tedx speaker, functional philosopher, games community advocate and technical optimist for an entertaining look at the eternal struggle for world domination via the technology we wield.

We’ll dive into good-bots and bad-bots and examine how they are used. We’ll explore some of the ways people are building tech for good and we’ll see what we can start doing today to create a better world for tomorrow.

About the talk

As more and more companies move to microservices the operations around them start to become messy and this becomes even more complicated when the services are designed to be single tenant. Let’s take a look on how we can simplify operations by using Kubernetes operators to deploy single tenant microservices in Kubernetes.

About the talk

You’ve setup a project and got it to run on your machine. Now comes the part to deploy, but where, and how? Cloud computing offers the ability to host applications anywhere, anytime. In particular the Oracle Cloud offers a wide range of APIs you can choose from. Particularly from a Java developer’s point of view, the Oracle Cloud Java API is well suited for enabling additional capabilities as plugins to well-known build tools such as Gradle and Maven as well as Java IDEs. In this session, you’ll see what this API is; what capabilities it offers for querying, searching, and deploying to Oracle Cloud; and, finally, a live example of build tools in action. Setup and configure cloud instances using well-known tools such as Gradle and Maven, no need to learn yet another tool or YAML.

About the talk

Operators in Kubernetes have until now mainly focused on single cluster applications, for example a Kafka cluster, but in reality these types of applications are usually part of a bigger application stack, which might include several applications using operators. Many users of operators are now starting to look at using operators as a way of deploying these whole stacks together. This is problematic in that the operator paradigm does not typically provide for passing data between operators, for example connection strings or configuration.
The KUDO project provides a universal polymorphic operator to simplify the building of operators for Kubernetes, in most cases just using YAML. Dependency chains are possible using KUDO, but have limitations which make automatic scaling of dependent applications difficult. Terraform provides this dependency chaining natively, so the addition of a Terraform provider for KUDO can make building and deploying dependent operators much more easy. In this talk I’ll show this problem in action, give an overview of both KUDO and the Terraform provider, and demo how the provider solves the dependency chaining issue.

About the talk

This session mixes many of the lesson learned in years while writing distributed software. First is “design for failures”, to be sure our code will never generates inconsistencies. Second is “stateless (almost) everywhere”, to be sure our compute power can be built in minutes. Third is “performance”, which has to be considered a feature itself while it is often a competitive gap between you and others. In this session we approach the “simple” problem of reducing the computation time of a CPU intensive application, using C#, Queues, Azure Batch and a bit of shell scripting.

With Kotlin we are able to write concise, expressive and safe code. Sounds like clean code, doesn’t it?
During this presentation we will recap what clean code is, we will highlight the importance of defining meaningful names and how to write clean functions and classes. Finally we will be able to learn more about the advantages of immutability and how to handle the errors in Kotlin.
By the end of the session, you will have a better understanding of what clean code means and you will learn a series of tips and tricks ready to be applied in your code.

About the talk

Most developers have experience with dependency injection (DI), whether it’s with Spring, Google Guice or CDI. But how many developers actually know how these frameworks make this magic happen? Or how dependency injection works in general? I, for one, didn’t have a clue. That’s the reason I built the Injectinator: my own DI implementation for Java SE. Creating the Injectinator has thought me a lot about DI and how the “magic” happens.

In this talk I will show you how Java reflection works, and how you can harness its capabilities to create your own dependency injection framework. All of this will be done with live coding.

About the talk

Callbacks… Callbacks everywhere… Callback inside the callback, and one more inside! Asynchronous JavaScript code is a pain. This session covers in-depth the asynchronous JavaScript code execution (with the event loop explanation) and its drawbacks. Consolidate your knowledge about callbacks, Promises, ReactiveX programming and async-await mechanism.

About the talk

We live in an ever-changing world. A world where technology is used every day – and a world where data breaches became so rampant that we don’t even notice them.
This session will cover the darker side of tech – the impact of data breaches in our everyday life.
We will talk about data breaches from a completely different perspective – they will be treated as big data.
We will be covering blazing fast queries on big data, database optimization, ensuring data integrity, bulletproof backups and web application security – we will also search for answers to the question why PHP and SQL can sometimes be an option while dealing with big data sets on web applications.

About the talk

Classes in JavaScript are problematic in a few important ways that many people are still not aware of, and they don’t really have much advantages over alternative patterns based on just functions. Let’s show the audience how to simplify their codebases by taking advantage of function composition!

About the talk

Keeping up with the state of web technology is one of the biggest challenges for us developers today. We invent new tools; we define new best practices, everything’s new, always… And we do all that for good user experience! We do all that to build the best possible web – it’s all about our users. But is it, really? Or do developers like to play with technology secretly loving the new and shiny? Or do we only pretend that it’s about users, and behind closed doors, it’s developer experience that matters to us? Did we lose direction? Is it time for a critical look at the state of the web and the role JavaScript plays in it?

About the talk

For years, web developers and app developers have been siloed, looking at each other with jealousy. How come these people get to do push notifications? How come these people have such a simple build process? And why can’t we all just work with the same codebase?

A PWA (Progressive Web App) marries all these needs together, starting with a run-of-the-mill website and adding features as they’re appropriate. The most interesting part: You can start with a website you’ve been working on right now.

In this talk, Lemon will take you through the process of starting with a simple HTML website add add features like caching, notifications, desktop installation and offline mode to create an app that’s as interesting and dynamic as you’d want it to be.

About the talk

Most of you probably heard about the distributed caching being the most common application of Hazelcast – but I bet not many of you heard about CRDT, HyperLogLog, or CP Subsystem. During this talk, we’ll go for quick journey around Hazelcast’s ecosystem, revise basic functionality and have a look at some of the hidden flavors. Even if that’s way too much for your use case, there’s still a lot for an engineer to learn from studying these concepts.

About the talk

Over the past year, Service Mesh has emerged as a critical component of the cloud native stack. It makes communication between service instances flexible, reliable, and fast, so developers can focus on adding business value and letting the mesh does all the complex non-functional work like service discovery, load balancing, encryption, authentication, authorization, support for the circuit breaker pattern, and other capabilities.

In this session we’ll provide an introduction to service mesh, starting with somehow the philosophical questions: do we really need a service mesh? what it can do and why people are interested in it ? Going it really to make all our problems disappear ? We’ll also explore how it simplifies application design and also where it adds complexity. All with some demos that highlights how the new micro services architectures as well as legacy monolith applications could benefit from service mech!

About the talk

In this session, packed with demos, I will tell you what I learned from various DevOps implementations and show you how I handled code reviews, continuous integration, infrastructure as code, database deployments, Feature flags and continuously delivering our applications to end users.

About the talk

At Pipedrive, we deploy our changes to different types of environments in 3 datacenters up to 400 times per day, which includes ~120 deployments to production daily. Considering these numbers, we should be flexible enough to deliver new features in a fast and reliable way. I want to introduce the processes that helped us to enable this pace, what tools we have implemented so far, and what challenges we have ahead.

About the talk

Java EE has been re-branded to Jakarta EE and moved to truly open source governance under the Eclipse Foundation. This session overviews what this means, offers a brief tour of the first release – Jakarta EE 8, explores current state and looks to what the future might bring including some key challenges. We will also discuss how these challenges can be overcome through active community engagement.

The technical contents of Jakarta EE 8 is mostly the same as Java EE 8 – it solidly enables HTTP/2, Server-Sent Events (SSE), JSON and aligns the platform with Java SE 8. It includes a much awaited security API overhaul as well as a slew of critical updates to APIs like JSF, JPA, JAX-RS and CDI. The true difference is how Jakarta EE is evolved in the open.

You should come to this session with your thinking caps on and your sleeves rolled up. There is much to help move forward together that really matters.

About the talk

This fast-paced, demo-driven, entirely slide free session will show you the many ways of effectively deploying a Jakarta EE application to Azure. We will start by deploying a local Jakarta EE application to basic IaaS on Azure. We will then deploy the same application to a managed Azure PaaS. Finally we will deploy the application to Azure using Docker and Kubernetes. We will discuss the trade-offs of each approach on the way, offering guidelines for which approach might be best for your application on the cloud. At the end of the session, you will have all the demos on GitHub so you can explore them on your own.

Key Points

• How to deploy a Jakarta EE application on Azure using IaaS.
• How to deploy a Jakarta EE application on Azure using PaaS.
• How to deploy a Jakarta EE application on Azure using Docker and Kubernetes.

About the talk

To get the most out of the agility afforded by serverless, it is essential to build CI/CD pipelines that help teams iterate on code and quickly release features. In this talk, we demonstrate how you can use infrastructure-as-code (IaC) models to build effective CI/CD release workflows to manage serverless deployments on AWS, using tools like AWS CodeBuild, AWS CodePipeline, and AWS CodeDeploy. Specifically, we focus on how to automate safer deployments that can be monitored and rolled back automatically.

About the talk

Designing, deploying and maintaining APIs for your mobile application is a challenge. In between authentication, authorization, data access, notifications, offline devices and the usual non functional requirements of availability, scalability and shrinking budgets.
During this session, I will show you how to deploy a GraphQL API, without requiring to be an API expert. I will show you how to easily integrate an authentication wall, with minimal coding. By attending this session you will be able to accelerate the development of your web & mobile applications by using simplified backends in the cloud.

About the talk

Nowadays “Artificial Intelligence” is everywhere! And rightly so, it does enable us to do really cool things, things we couldn’t even imagine doing just a decade ago. In fact, it sometimes just feels like magic. This ‘magic’ behind it is often powered by “Machine Learning”. But even “AI” has its limitations.
I’ll show examples where “AI” and ML have failed (sometimes with horrible consequences) and will explain why failures are unavoidable in ML but also mention what we can do to reduce them in the future.
Furthermore, I’ll showcase how current AI implementations discriminate against minorities and how that in some cases even leads to a higher risk of death for those groups.
I’ll cover the bias that humans introduce and I’ll explain how poor choice of data makes our world even more unjust than it already is.

The takeaway for the audience: AI can fail and sometimes it has horrible consequences. Why is AI so hard to “do right”? How can we make AI better?

About the talk

Every interaction a malware has with a system produces an artifact – Windows also adds to this a wealth of redundancy. But does inconsistency signal a red flag? We explore patterns that lead to false conclusions and connections for validating assumptions, by analyzing Prefetch files. The question we’re ultimately trying to answer is “has this system been compromised?

About the talk

In the past fourteen years of my career, I was a part of several “24/7 Duty teams”. 24/7 means that you would need to stop your lunch or wake up in the middle of the night from an ALERT on your phone, and solve a problem. Even with a detailed notification message, I would still need to check numerous logs, examine the life system, and monitor the customer traffic. It would take ages.

Monitoring was never just a topic that went away after one or two IT-conferences. It is now as relevant as it was ten years ago. Over the years, I saw many companies developing cloud monitoring solutions that turns this tedious process into a fun exercise of looking at beautiful dashboards. What took hours before now takes just a glance at graphs that are generated automatically. The unique data analytics platforms enables technical teams, especially DevOps, to accelerate this kind of monitoring and ensure application uptime.

So let’s dive deeper into these topics together and find out how developers and owners have more appropriate and effective control over the systems, and dramatically improve customer satisfaction.

About the talk

Extracting data from documents and making sense of the information is a very mundane, cumbersome, error prone and labor intensive task in many organisations. Up until recently, it was very difficult to automate Document Processing and was often only viable in very mature environments with a very high volume of documents.

In this talk, Jens will showcase how UiPath’s Hyperautomation platform, with built-in Document Understanding and Human-in-the-Loop capabilities, can be used to automate business processes even if they include the processing of unstructured or semi-structured documents.

About the talk

Jupyter Notebooks are becoming the IDE of choice for data scientists and researchers. They provide users with a nice exploratory environment where they can quickly research and prototype different models and visualize the results all in one place. Notebooks are easy to share and can be converted into documents/slides to present to stakeholders.

With widget libraries like ipywidgets and bqplot, users can create rich applications, dashboards and tools by just using python code.

In this talk, we will see how we can build interactive dashboards in the Jupyter notebook. In the first part of the talk, I’ll introduce the widget libraries and walk you through the code of a simple example so we understand how to assemble and link these widgets. Then we’ll look at a few case studies including building dashboards from server logs and examples in finance and machine learning.

The “clash” between classical cryptography and quantum computing

Quantum Technology is likely to be the next big step in computing. The stakes of an adversary owning huge computational power are high, especially when it comes to protecting cryptographic secrets.
In this talk, you will learn the basics of quantum computation and the current state of quantum technology. We’ll then take a look at two attacks based on Shor’s and Grover’s algorithms, which are the killers of many cryptosystems like RSA. Finally, we will dive into some ways to defend against quantum adversaries, including a way of securing communications using quantum intrication.

About the talk

Cryptography is a vital component of cybersecurity. Despite the apparent simplicity of modern cryptosystems, any small mistake can bear disastrous consequences.
This conference takes a deep dive inside several cryptographic disasters of the last decade caused by simple implementation errors, often contained in one line of code or a small cryptographic oversight.
Through the source code or reverse engineering of the affected software, we study the root cause and the way to exploit each failure.

Passion and great ideas build a company. Add talented people and you build a great company. How do you preserve the same passion and the greatness as your company grows? Do you change your ideologies, do you compromise or do you forget who you were? Here’s a talk that speaks about precisely that. We start a company out of passion, out of love for what we do and with a close knit group of people, keeping certain ideologies in mind. These people work hard and adhere to these ideologies. Eventually the number of customers increase, you make profits and you add more employees. As you grow, do you manage to keep the same culture alive with 200 people that the original 6 employees were proud of? This talk explains the journey of the growth of my company from 6 to 200 and whether or not we could preserve the culture and how you can do the same in your organisation.

In these past few years, agile methods became a vital part in the software development process, but are they really applicable for all types of projects and team sizes?
A while ago, our company changed the way we approach project development because the team noticed that standard SCRUM-ish methods aren’t fully compatible for us, so we developed our own, modified version of agile. In this talk, I will showcase how powerful this approach is and how you can use it to find problems, and eventually resolve them.
– what is real agile, what we as industry are doing wrong, how we can improve it, a lot of examples from my personal experince
– maybe my favourite topic at the moment, getting a lot of traction at social media (i am writing a lot about it), maybe very important for the future and understanding bhow to build better software

While most people think of symbolic computation as synonymous with computer algebra, it represents a powerful paradigm for representing and working with information in a unified way.

This talk will explain how, even though most data science is concerned with numeric or textual data, symbolic representation simplifies the processing of data, the construction of classical and machine learning models and even simplifies the data science worflow from exploration to reporting and deployment.

The talk will be illustrated with examples and live coding from domains such as computer vision, natural language processing and generative AI content.

Every day, millions of advertising campaigns are happening around the world.
As campaign owners, measuring the ongoing campaign effectiveness (e.g “how many distinct users saw my online ad VS how many distinct users saw my online ad, clicked it and purchased my product?”) is super important.
However, this task (often referred to as “funnel analysis”) is not an easy task, especially if the chronological order of events matters. So, while the combination of Druid and ThetaSketch aggregators can answer some of these questions, it still can’t answer the question “how many distinct users viewed the brand’s homepage FIRST and THEN viewed product X page?”
In this talk, we will discuss how we combine Spark, Druid and ThetaSketch aggregators to answer such questions at scale.

Bolt is one of the fastest-growing companies in Europe and so are our data volumes. In our day-to-day operations, we heavily rely on data for decision making and machine learning. At some point we realized that traditional ETL approach is not performant enough for us any more. So we decided to switch towards real-time stream processing and event sourcing. It was a long and bumpy ride which has provided us with significant benefits.

During this presentation, Ruslan will share his team’s experience migrating all company’s infrastructure to real-time stream processing, problems team has encountered, short-cuts they have made, and lessons learned along the way – Kafka cluster management, structured and un-structure data processing, data (de)duplication, reliability guarantees, making migration process as seamless as possible.

It is a common illusion that Product Managers in the current reality, can continue working to define products, without thinking about security aspects, and that this can be done at a much later stage in the product lifecycle. How can we turn the Product Manager to be a real security ambassador?
We’d like to show how a very comprehensive security program, managed by a dedicated security office in cooperation with a professional Product manager, can raise the “security organizational conscience” and can successfully integrate in security aspects in every product, with emphasis on agile development lifecycle.
We believe the Product managers should be the pioneers to start a more “security driven product management” approach, leading to better and secured products, in a world of cyber security growth and Big data sharing and analytics, which cannot survive without security elements intact as the basis of every product design and architecture. We will address the security from the process point of view and from the content point of view. We want to provide a real example illustrating why, when and how the changes should happen.

Threat modeling is a very powerful tool within application security. This session explains how we can optimize threat modeling and improve the process outcome, and how we can handle a new dimension in the model since the containers usage requires attention to additional aspects easily overlooked.
This session explains how we can optimize threat modeling and improve the process outcome, and how we can handle a new dimension in the model since the containers usage requires attention to additional aspects easily overlooked. We’ll start from the common principles of threat modeling, purpose and expectations from the process, and continue with different approaches, roles, and metrics we can apply to the process. We’ll deep dive into the new aspects inserted by containerization of applications for both legacy monolith and modern micro services architecture. We’ll conclude with examples where proper threat modeling and mitigation of risks reduces the impact of vulnerabilities recently reported in Docker and Kubernetes.

Kubernetes Operators are the next phase of the journey towards automating complex applications in containers. The Kudo project introduces an easy way to build Kubernetes operators using declarative YAML. Many Operators that exist today handle initial deployment, but they don’t provide automation for tasks like binary upgrades, configuration updates, and failure recovery. Implementing a production-grade controller for a complex workload typically requires thousands of lines of code and many months of development. As a result, the quality of operators that are available today varies. The Kudo project provides a universal operator to enable automated creation of operators for Kubernetes, in most cases just using YAML. In this talk, I’ll introduce the Kudo project, and demo the creation of a Kubernetes operator using Kudo.

You’re a smart cookie. If you have to deliver something on a tough deadline, of course you will. And because we don’t have time, we rely on things that used to work in the past, or the things that everybody else around us does. Yet too often these solutions aren’t ideal for your particular context. And so before you know it, the conversion goes down, or traffic shatters, or there are more complaints in your customer support. How do we avoid that?

By testing, of course. In this session, Vitaly Friedman, the creative lead of Smashing Magazine and a consultant working with European Parliament, Haufe, Marc’o’Polo, Zalando and a few other companies, will show some complex, smart interface design patterns that work. We’ll look into hamburger icon navigation, mega-drop-downs, general navigation patterns and search.

Keep in mind: you won’t be able to unsee the things you’ll see in this session.You’ll leave with a toolbox of practical techniques that you’ll be able to apply to your work right away.

Modern software development methodologies and approaches help to increase delivery speed while still caring about software quality. However, if we think about manual regression tests, they are not only time consuming and repeatable, but also feedback time is quite high. These are the reasons why regression tests are often automated.
Automated tests can provide results faster and it’s possible to execute them more frequently than manual ones. They can decrease the overall time needed for tests, but what’s probably even more important, they allow to test and receive feedback earlier in the development process. It’s essential if we want to release and deliver business value faster and more frequently.
But what if we have more and more tests and even automated execution of them takes too much time – 10 minutes… 30 minutes… maybe even hours? Should we consider the ability to execute full tests set just a few times a day as something normal? Is adding more compute resources the only option to reduce the execution time? Or maybe there are too many high-level tests and some of them should be replaced by low-level ones according to the Test Pyramid? Is the Test Pyramid still valid in the cloud world?
During the presentation, you will see how the serverless cloud services like AWS Lambda may be used to run tests in the highly parallelized environment that can speed up test execution even hundreds of times.

About the talk

Design is subjective, both visually and how people experience products. It is reflective of who we are as human beings and is capable of shaping the world around us. Unfortunately, the comfort of privilege can be found in biased design throughout history. Designers and engineers have a great responsibility to bring inclusivity into our work, both in creation and in validation. It is necessary for us to identify our biases, see how they manifest in our designs, and understand how to counter those biases with diversity in our teams and testing pools.

In this talk, Mark will talk about how privilege and comfort create biases that influence our designs, showcase some examples of how this exclusivity has manifested in everyday products, and take a look at how Artificial Intelligence is a perfect reflection of our shortcomings in the equity of inclusivity.

The rapid development of the fourth industrial revolution and its new functionalities opened the pandoras box of data collection from the industrial environments.

The only downside of this development is that industrial controls don’t tend to keep up with this changes and equipment with decades of runtime are still in place controlling critical processes.

Bringing connectivity to this devices gives companies new insights in the production environment but also rises new challenges and threats.

We will have a look on how we ended up here and what can be done to better protect this systems.

Most modern embedded systems employ an operating system [OS] of some kind, and this necessitates some critical design decisions. Should you obtain a commercially available OS, choose one of the “free” offerings, or develop one in-house? If the acquisition of a commercial OS is planned, how do you make the selection? This session reviews in detail all the facets of the make vs. buy and OS selection decisions – both technical and commercial – for an OS on an embedded design.

Machine learning (ML) is impacting a wide range of markets and applications, ranging from mobile, wearables, IoT to Industrial applications. While today most of the computing happens in the cloud, intelligence and processing capabilities are rapidly moving to endpoint devices. Especially in IoT and Industrial applications, decision-making often needs to happen in real-time at the data source – enhancing security and cutting down on network energy consumption, latency and bandwidth usage. Such applications require scalable and efficient hardware and software solutions to deploy ML across various performance points.

This presentation will talk about how AI applications can be efficiently implemented and accelerated on the extremely low-power, low-area endpoint devices. Furthermore, the talk will also show how open source software for ML solutions can be utilized to address emerging use cases. This approach will enable developers to efficiently tackle the challenges in this space and make it easy to create and deploy ML applications.

About the talk

How good are your tests? Would they still pass if the tested code was changed? If so, there may be problems with your code, your tests, or both!

Mutation Testing helps reveal these cases. It makes lots of slightly altered versions, called “mutants”, of each of your functions or methods, and runs each method/function’s unit tests, using each of its mutants instead. If a mutant makes any test fail, that mutant “dies”. If there are any “survivors”, that implies that there are flaws in your code, your tests, or both! Your code might not be meaningful enough that a slight mutation would change the behavior, your tests might not be strict enough to catch the difference that the mutation made, or both!

This talk will tell you what mutation testing is, its benefits and drawbacks, how to use it, and how it works under the hood. There will be examples, and a list of tools for many popular languages and platforms.

You will come away equipped with a powerful new technique for making sure your tests are strict and your code is meaningful.

When we develop a new web application, we often put a lot of work on the design, on making it beautiful and usable. In other words, we want our web app to be effective, efficient, and satisfying for the user. But a lot of times we don’t think about the user experience for people with disabilities, including people with age-related impairments.

For the web, accessibility (a11y ) means that people with disabilities can perceive, understand, navigate, and interact with websites and tools, and that they can contribute equally without barriers.” (Source: W3C – Web Accessibility Initiative). Our role as frontend and web developers is to create clear interfaces to make people understand and care about data, independently of their disabilities or impairments, but what we, developers, often forget is to ensure that the code we write follows the Web Content Accessibility Guidelines (WCAG), and the only way to achieve that is testing, either manual or automated.

Automated web a11y tests can free up our QA team from manual testing every part of our application…but…they can’t automatically, and magically, make our site accessible.

We should use automated a11y tests as one step of a larger testing process. Don’t forget that only 20% to 50% of all accessibility issues can automatically be detected.

I will show you some testing tools, libraries and techniques to increase the a11y test coverage of your code with a simple React application example.

Speech will be about real cases of GraphQL integration in projects, which was working on REST API before. Now we have got definitive information about results after migration to GraphQL. This information will help everyone, who is going to migrate current REST API to GraphQL. Examples will be PHP Yii2 applications – e-commerce, microservices system and simple information site.
Points are:

• Advantages and disadvantages of GraphQL compared with REST
• How can Backend developer delegate logic of information collection to Frontend developer and make Backend develop more free for his work
• Showing real examples of migrations in real projects
• Disadvantages, which met us only when we ran it in production
• Showing cases, where GraphQL gives a lot of benefits and speed up develop progress and server response and, on the other side, when GraphQL make shoot in
  our leg and very small benefits
• Special points about asynchronous work with GraphQL and PHP (ReactPHP, amphp), comparing with JS

Have you ever missed a release because a step of your pipeline was broken and nobody took the initiative to fix it?

In my experience, the statement “everybody in an Agile team should be responsible for Quality”, sometimes leaves a gap in the personal responsibility that each individual has. This can cause, from delays of deliveries to fights within the team.

In the first part of my presentation, we will identify some of the causes of such a situation. In the second part, we will explore the solutions that can remove each of the causes and look into ways that they can be applied. Finally, we will discuss how to facilitate and monitor the implementation of the solutions by the whole team.
