Career
Is it possible to accelerate your career 10 times? I believe yes. Well, maybe you guessed I meant 10 as a binary number though :)
It's a fact, at least half of what it takes for an accelerated career has (almost) nothing to do with your technical skills.
In this talk I'll focus on the habits, attitude, activities and non-technical skills that enhance and accelerate your career growth - and with some discipline on these you can reap the results.

Tests & Quality
Comme développeur, on nous demande toujours d'aller plus vite sans jamais sacrifier la qualité. Je raconte comment j'ai réalisé ce miracle durant le développement d'une application web en appliquant le TDD (Test Driven Development) assisté de l'outil de test Cypress.io. Suite à ma présentation, vous n'aurez plus d'excuse pour ne pas faire de tests!
Java & JVM languagesPerformance
While a microservices architecture is more scalable than a monolith, it has a direct hit on performance.
To cope with that, one performance improvement is to set up a cache. It can be configured for database access, for REST calls or just to store session state across a cluster of server nodes. In this demo-based talk, I'll show how Hazelcast In-Memory Data Grid can help you in each one of those areas and how to configure it.

Security
The number of Unicode code points has never stopped to grow just like its integration in modern technologies. Your web application is likely to support input and output formatted in UTF-8 character encoding. In this talk, you will learn about the security implications. What are the potential side effects of normalizing a UTF-8 string? How encoding can affect security controls? What are the security risks brought by punycode domains?
Java & JVM languagesData Science
A typical workflow of a Data Scientist involves some level of exploratory data analysis. If you’re using Python when working with your data, you are probably quite familiar with packages like pandas, matplotlib, and others. Switching from pandas to Spark - how do you explore your data? How do you visualize it? In this talk, I’ll take a dataset and will explore it with Spark using IntelliJ IDEA and Apache Zeppelin.
DevOps
You’ve been to a restaurant before, right? Have you noticed how everything is structured? Everyone has a job and there is a chain of command. You can’t just walk into the kitchen and tell the cook how you want your steak done. Kubernetes is actually very similar to this. You will deploy some pods that do specific things and set the rules of communications that dictate how they all talk to each other.
Accessibility
Accessibility is often seen as a costly endeavour, blocker to creative design, a complicated technical solution, or a problem left to QA.
Accessibility is an opportunity to create an excellent experience for all of your customers. Understanding your role in bringing that experience to the table, might be easier than you might think.
I will share some tips and tricks for making accessibility a simple part of your process.

CareerManagement
There is a set of commonly held beliefs which (if true) make age discrimination in Tech perfectly logical behavior. If we wish to end age discrimination (and eventually we all do) we have to challenge those beliefs. Unfortunately, most of us are really sure that those beliefs are accurate reflections of reality. I will identify those beliefs and present evidence to debunk them.
Artificial IntelligenceUX & UI
Inspirational talk on how AI and Machine Learning is shaping the future and how roles and our processes in design and development will be shaped by it. AI will help designers and developers create better experiences because AI is a creative partner, "your Augmented Intelligence.” Becoming familiar with AI will ignite new thinking, shift approaches, deliver new tools, processes, and concepts.
Blockchain
Blockchain is an immature technology in a space polluted with scams and snake oil. It is easy to become skeptical about a tech that promises so much and hasn't delivered a thing outside of some dicey investment opportunities. But the potential is real. And the tech is neat. This primer will cover the fundamental concepts from an engineering perspective, as well as some of the emerging open source platforms you can start experimenting with today.
Management
Most dev teams have a code review process but not all code review processes work as well as they could. I'll talk about why your team should bother doing code reviews in the first place, how your team can derive the greatest benefit from a healthy code review process, and how vital it is to your dev team culture. Most importantly, I'll explain why you should have your interns review your most senior developers' code.
Architecture & Design Patterns.NET
What is legacy code? Did I just write more of it? ASP.NET rebooted itself to make it more maintainable and performant. Let's learn to build highly maintainable code as well. We'll look at the low-hanging fruit to get you on a path to avoiding the common pitfalls and reach for the easy wins. You can avoid legacy.
AccessibilityUX & UI
In 2018 I built all the software for "This Is Nowhere" an innovative app-based theatre experience in downtown Halifax NS. One of the many unique things about this project is how we worked closely with accessibility activists from the beginning and considered accessibility throughout the production process.
This talk will share what we learned about accessibility, and the surprising ways that it helped far more people than expected.

Architecture & Design Patterns
Dealing with date and time in code is tricky: units are not multiple of ten, time zones and DST are annoying...
In fact it's much more complicated! Not only do sun and moon influence our calendar system, but also Sumerians, Caesar, Norse gods, tidal rise, the pope, steam engines, and Einstein. Let me entertain you with fun facts about legacy support and leaky abstractions in time, or a fix for a >1500yr old bug with >400yr roll out duration.

Python
async, await, generators, tasks, coroutines, oh my! Let's learn how this often overlooked module can help you write concurrent code, without starting multiple threads or using multiple CPU cores. You'll leave with a better understanding of what cooperative multitasking is and how you can use it in your own projects.
Cloud ComputingNode.js
You probably don't manage a hockey team but I'm sure you have a number of tasks that you do regularily that would benefit by being automated.
I could make my life easier by automating the the process of managing my team. Calculating whether or not it would be worthwhile to expend the effort. Under estimating how long it would take but being happy with the results. Along the way I'll explain serverless concepts like FaaS, triggers & cloud db's

Python
In the 13 years since Python 3 started diverging from Python 2, Python 3's gained many new features: from co-operative async programming, to optional static typing, and to string templating. These solve performance issues, maintainability issues, and developer productivity.
In 40 minutes, we'll show you the best new features from the last few releases of Python, why they're in Python, and how to use them. We'll have example code!

MobileUX & UI
How can designers improve the user experience of their mobile apps, reduce abandonment rates, and increase revenue? People want convenience, speed, and efficiency when using their mobile. However, many apps don’t follow established UI design standards and best practices, as a result, frustrating people with bad UX. Good and bad examples will be shown as we cover techniques, strategies, and best practices to elevate mobile UX.
CareerStartup
Who would have thought putting 140 charachter messages about one's life online or having a virtual farm game could ever be popular ? Then again, many of us have those weird (but sometimes brilliant) ideas. So you have the idea that will make you the next Twitter or Facebook. But how do you actually turn that into a successful service ? What hurdles do you have to take and what pitfalls will you need to avoid ?
Data ScienceMachine LearningPython
Scikit learn, decision forests, pandas, numpy, Jupyter Notebooks, where do I start? Machine learning can help you analyze data and get information to make better decisions, but it can also be intimidating. In this session I'll explain the basic steps required to train a machine learning model then we'll see how that looks in actual code using Python code in a Jupyter Notebook.
Architecture & Design PatternsCloud Computing
Google Cloud Run’s use of Knative introduced a portable Serverless solution built on top of Kubernetes. In this talk, we’ll recap the basic guidelines, use cases, and benefits of a Serverless architecture. Getting up and started, you will learn to take advantage of containers and the Ambassador API Gateway to serve event-driven application workloads and save costs using your existing Kubernetes resources.
Architecture & Design PatternsSecurity
Health data is some of the most private information your app can collect. You have a duty to your users to keep that data private, secure and encrypted. You also need to adhere to strict laws protecting that privacy, while scaling your company.
You'll learn about Protected Health Information (PHI) and how to protect it on Amazon Web Services.

This talk will discuss the challenges of building HTTP API SDKs and what our two pizza sized team has learned from building SDKs for the Microsoft Graph. Microsoft Graph is an API with more than a billion users and 100K+ active client applications.
PerformancePHP
Caching personalized data is hard. Most systems just avoid caching stateful data altogether and use AJAX or ESI to get the job done.
In this presentation Thijs will present a developer-friendly way to cache templates in Varnish and parse the stateful data "on the edge" by directly accessing the application's Redis session store in Varnish.
This can be leveraged with a simple template filter in both Twig for Symfony and Blade for Laravel.

Most of us are probably aware of code smells, but there are other coding horrors that should trigger alarm bells whenever we see them. Like a good horror movie, coding horrors should scare us when we find them, because they're often symptomatic of deeper problems. So let's take a short tour of some of the greatest horror movies ever made (and a few turkeys); and some of the most worrying code horrors that I've seen.
DevOps
The end is nigh. Your application is almost ready and you will need to deploy it. And with the deployment, the endless tweaking to actually get everything running in a production environment. If only there was a way to test everything in that environment first… This is where containers will come in to save the day. With container, you not only run your code in an environment similar to the production server, it is the production environment.
DevOpsSecurity
OWASP, a nonprofit composed of security experts from around the world, provides a number of free and open source tools designed by security experts to help your secure your applications. Learn how to integrate these tools - from active penetration tests to project dependency checkers - into your DevOps pipeline and deliver on the promise of continuous security.
Artificial IntelligencePython
Object Detection has become very popular during the last few years. It may look complex from afar,How to train a model on my own dataset ? How do I label data? Which architecture should I choose ? What are the standard metrics to evaluate my model ? How to deploy my model ?
In this talk, we will go over a concrete example to present the typical journey to deploy an object detection application in python and answers those questions and many more.

DatabasesDevOps
Web technologies have come leaps and bounds. But are you still using the tired old database from last generation? Let's look at the methodology of microservices, compare it to bounded contexts, and look at ops tasks for micro-databases. Let's tour all the flavors of databases, understand their pros and cons, and when you would choose it. You'll leave with a roadmap for moving from data-monolyth to micro-databases.
Architecture & Design PatternsPHP
We talk a lot about various architectural approaches. Unfortunately, we don't talk as much about the environment in which we apply those techniques - the framework. In this talk I'd like to show you how you can apply virtually any kind of approach - DDD, CQRS, Event Sourcing, Hexagonal Architecture, and many more, virtually everywhere. There are no silver bullets, but with the right approach, we can get pretty close to that goal.
ManagementUX & UI
At McGill University, 1700 staff manage 900 sites that generate 10M page views per month. McGill's new digital standards define our criteria for building sites in areas such as usability, accessibility, brand adherence, security and more, in a succinct, user-friendly format. These standards are aimed at helping staff build better sites that provide positive user experiences. Find out how we produced and launched this initiative and the results.
Ruby
AWS is the perfect platform to run a Rails App at scale. In this talk, you'll learn how to host and deploy your app using Elastic Beanstalk with the following features and technologies: SSL termination at the ELB load balancer (including a free SSL certificate), caching using Redis on Elasticache, and a database running on RDS. You'll learn how to deploy with zero downtime using a continuous delivery service.
CareerManagementDocumentation
They say a picture is worth a thousand words... I've learned that I can replace a 20 page document with a 2 page diagram that explains it all. Words do not help because words require interpretation.
However images, diagrams, pictures speak volume and their meaning is universal. In this talk I will demonstrate how to transform long documents into simple diagrams; and how you can leverage that power of communication to convince almost anybody!

Tests & Quality
Deploying directly to production and testing in live can be scary, especially when your business can’t afford to lose any of its traffic; but having a staging environment isn’t always an option.
Yet with the right approach, a mix of clear process and good tools, the risks of deploying straight to production can be mitigated.

Architecture & Design PatternsPHP
Separated layers are one of the fundamental principles of software design. Your framework is just the topmost layer, and your business code should not depend on it. While we will touch a few package design basics, the focus is on how to actually DO it, while still avoiding overengineering and clutter. We’ll also take a look at Deptrac, a tool to visualize layer dependencies during development.
Architecture & Design PatternsCareer
The career path to the Architect role is broadly regarded as the "pure" technical way forward, as opposed to leading teams and projects. And that's wrong.
An architect has many responsibilities requiring effective communication and collaboration with practically all other roles in the project team and beyond.
Join me to hear which soft skills I think are most important for an architect to be successful - and how obtaining them can be hacked.

Java & JVM languages
How can we improve the efficiency of an existing web application? We could completely rewrite it, leverage more concurrency and even reactive features. But is it really worth it if we don’t even measure and track the relevant metrics? In this talk, Stéphane will work on an existing Spring Boot MVC application to make it more efficient. He’ll use out-of-the-box metrics, add new ones to measure, and keep an eye on capacity gains with dashboards.

Architecture & Design Patterns.NET
In the classic paper Data on the Outside versus Data on the Inside Pat Helland argued that data within a service boundary should be treated differently than data residing outside of it.
Here, I shall argue that the same applies to messages. Inside a service boundary messages are tightly coupled to the corresponding data manipulations. Outside, the world is much more hostile and less predictable and communication strategy needs to be adequate.

In a distributed system messages sometimes get lost or duplicated. That's a fact of life. It is really hard to execute business logic that assumes one trigger equals one outcome when a trigger can be lost or fire twice.
One way of dealing with the problem is taking advantage of natural idempotency of some operations, e.g. adding element to a set. But let's face it, most code is more complex than that. Join me an explore some alternatives.

Accessibility
What do you know about ARIA (Accessible Rich Internet Applications)? If you've heard of it, you might know that it's for making websites more accessible, right? What if I told you that bad ARIA is actually worse than no ARIA at all?
Some accessibility is built-in to web dev, so ARIA isn't always needed. But when it is, it's crucial to understand what you're doing, so you don't end up with a site that's less accessible than when you started.

TypeScript is an odd duck. A language designed by C# engineers of an object-oriented persuasion. But built on JavaScript, a slapdash ode to Scheme. Is there room for both approaches? Of course! We're engineers. We just use what suits us and happily ignore the rest! This talk reduces TypeScript to the features functional programmers love. Get ready for a lot of interfaces and generics, and not one mention of classes or (shudder) access modifiers.

Content Security Policy is the most effective browser measure for web application security in a decade, and one of the reasons why browser developers start removing other security safeguards like their Cross-Site Scripting auditor. But creating an effective Content Security Policy is not always trivial. This session will discuss lessons learned from many CSP projects: what is working, where are issues, and what features can we look forward to?
Go
What makes Go the “language of the cloud”? Should I learn it? How and why does Microsoft use Go? We’ll take a whistle-stop tour of Go and its ecosystem and then explore it hands-on with code, tools, and techniques for web applications, APIs, CLIs, containers & serverless. This talk is for both aspiring and current Go developers ("Gophers") as well as anyone who is just Go-curious!

As your code moves along the development and deployment pipeline, it becomes increasingly expensive to remediate security vulnerabilities. We will walk through each stage of this journey to introduce low cost and open source solutions to help you identify security issues before they are exposed to hackers. I will teach you how to use hacker tools to hack yourself first and protect yourself from breaches, on a budget.
Architecture & Design PatternsCloud Computing
In this talk we’ll explore mechanisms for observing and debugging distributed systems, with an eye towards taking an existing codebase that lacks observability and evolving it over time. In particular, we’ll focus on monitoring and metrics, logging, and distributed tracing tools that let us track transactions which span multiple services and execution contexts.
Cloud Computing.NET
Together, we will create a highly-scalable serverless search engine using Azure Functions and Azure Search that performs 3 tasks: listening for new packages on NuGet.org (using a custom binding), indexing packages in a distributed way, and exposing an API that accepts queries and gives our clients the best result. Expect code, insights into the service design process, and more!

Email has been around forever and is taken for granted – but it has become more complicated in recent years. Newer features like SPF, DKIM, and DMARC are misunderstood and, judging by the questions I answer on Stack Overflow, many are getting even simple things wrong. So we'll go back to basics, review how email works, how to avoid common mistakes, take advantage of its new powers, and stay out of the spam folder of history.
Java & JVM languages
Java ne cesse d’évoluer et de plus en plus rapidement, à un tel point qu’il est parfois difficile de savoir où l’on en est ! A l’aube de la sortie de Java 14, je propose donc de présenter dans cette session technique les principales nouveautés ajoutées dans les dernières versions de Java. Et comme ce sont parfois les petits détails qui font la différence, nous allons aussi discuter de nouveautés mineures qui peuvent cependant être intéressantes.
JavaScript
Javascript is probably not the first language that pops to mind when thinking about Game development. It's not particularly fast, OOP support is a little special and most games don't really target the browser. Yet a small but growing community is doing just that - with amazing results. This talk will demonstrate how to build a Steam ready desktop application in JavaScript, in 45 minutes.
JavaScript
JavaScript is an interesting language. It can mimic almost any style you want: procedural, object-oriented, functional, etc. In this presentation, I will take a simple problem and will solve it using different approaches. With each step, we will see the power of the new approach to take the complexity away, while still being the JavaScript we all love to hate.

Local variable type inference is without a doubt the biggest language feature in Java from the last couple of years. In this live-coding session, we push its limits and examine its behaviour through a series of 40 examples. We do this in the form of a quiz, and focus on situations where the type inference doesn’t work, or leads to unclean code. Come and test your knowledge of type inference, and learn how to use it well in practice!

Choosing the right evaluation metric for your machine learning project is crucial, as it decides which model you’ll ultimately use. How do you choose an appropriate metric? This talk will explore the important evaluation metrics used in regression and classification tasks, their pros and cons, and how to make a smart decision.
Modern software development sometimes feels like magic. Abstractions upon abstractions in operating systems, programming languages, frameworks, libraries and cloud services help us to solve complex problems fast in a reliable and scalable way. On the other hand, we are losing ownership and insights into how things are actually working under the hood. So should we trust all this magic?

MySQL has moved to a continuous release cycle and had been adding new features since version 8.0 has been released. So it is quite easy to miss the parallel bulk loader (CSV, JSON, TSV), Multi-values indexes, improved JSON support, the ability to clone InnoDB databases for faster replication startup, changes in SSL/TLS support, JSON schema validation, 3D GIS support, check constraints, and more. So get caught up today with the lastest from MySQL
Databases
You want your database storage to be safe, secure, and always available. MySQL Group Replication provides a fault tolerant, highly available, and elastic data groups. Groups can operate in a single-primary mode with automatic primary election, where only one server accepts updates at a time or be deployed in multi-primary mode, where all servers can accept updates. So you can scale from one to many servers without changing your application.
CareerManagement
Building a healthy development team has never been more challenging for startups, but this is not another talk about hiring. It is about necessary endings. This talk will not prescribe the right way of growing an engineering team. It is about a balanced trade-off. Motivating and shaping software engineers is a no-brainer, however, letting people go has never been popular thus crucial to the health and growth of the team. I'll explain why and how.

PHP has its own treasure chest of classic mistakes that surprises even the most seasoned expert : code that dies just by changing its namespace, strpos() that fails to find strings or arrays that changes without touching them. Do that get on your nerves too ? Let’s make a list of them, so we can always teach them to the new guys, spot them during code reviews and kick them out of our code once and for all. Come on, you’re not frightening us !

With a clear configuration language you can manage countless services (providers in Terraform) and ensure they are kept in sync with your deployment needs. Learn how to build out some of the most common patterns and infrastructures against AWS, and start writing your infrastructure as code today.
Data ScienceUX & UI
It is becoming clearer that Data driven UX is providing us with more sound design recommendations. If you have ever felt frustration as a result of something mal functioning, chance is the solution might not be what we think. Data analytics can help bridge the gap between randomness and predictability. In this session, we explore the belief that UX is more than art and how methodology can help implementation in a data science ecosystem.
Architecture & Design Patterns
Produire avec confiance une architecture maintenable évoluant naturellement en direction de vos objectifs, les Fitness Functions, SLOs et autres pratiques de développement assurent à chaque commit le respect des caractéristiques que doivent satisfaire votre produit.
JavaScriptNode.js
In this session you’ll learn about WebAssembly: what is it, what problems it solves, how it works, and what makes it secure. That last point about security is an important one because that’s one area that gives many people pause when hearing the words ‘native code’ or that C++ can be used. Immediately, we have flash backs of plugins and pointers.
AccessibilityHTML & CSS
Do you know what accessibility is & why it's critical for 20%+ of your users? Have you ever heard of WCAG, POUR or ARIA? Accessibility should be a key element of our processes, but many people haven't even heard of it. In this introductory session you'll learn about assistive devices & technologies, accessibility standards & tools, and come away with quick & easy next steps for making your sites and applications more accessible to everyone.
Cloud Computing.NET
We all like building and deploying applications. But what happens once that’s done? How do we know if our application behaves like we expect it to behave? Of course, logging! But how do we get that data off of our machines? How do we sift through a bunch of seemingly meaningless diagnostics? In this session, we’ll look at how we can keep track of our application using concepts like structured logging and Azure Application Insights.

PerformancePHP
Generators are often described as a simplification of iterators pattern, but they are also very powerful to perform asynchronous treatments. We will dive into event loops and promises to understand why and how generators can help us to write maintainable asynchronous functions, especially in Php. We will conclude with some concrete use cases from our experience at M6 (French media group).
.NETNode.js
Do you want to build full-stack with your stack? We'll build an ASP.NET website using Blazor and WebAPI, a back-end service using Service Worker and gRPC. Then we'll build the same website with Node using Express, Vue.js, gRPC, and PM2. Along the way we'll compare and contrast these technologies to empower you to use JavaScript or C# front-to-back for your next project. You'll leave with functional samples, and a methodology to choose.
