Agenda

Friday 16 may

	Main room	Room 1
08:00 - 09:00	Registration & Breakfast
09:15 - 09:30	Welcome word
09:30 - 10:15	From data to knowledge Raw data is really hard to work with, especially when it comes in large quantities, and this is why most people don't realize the power they have at the tip of their fingers. Companies are being sold for billions because of their potential of generating large amounts of data. Even some seemingly not interesting pieces of data like web server logs can hold important secrets and can help you learn more about your users: usage patterns, uncaught errors, optimization opportunities and so on. How can we leverage the data we own or generate to provide additional value to the company and our users? are there maybe ways to gain insights on it without putting too much effort? how do we transform data to actionable knowledge? Search engine technologies have evolved to being one of the most powerful tools around, and they hold the key to those questions. Today we will learn how they work and how to make good use of them, anywhere. Itamar Syn-Hershko
10:30 - 11:15	F#’s Type Providers: The future of meta-programming in .NET Type Providers are a new addition to F#, introduced in the version 3.0 of the language. They provide an innovative way for library writes to create libraries that extend the F# compiler. This allows library writers to add meta-programming features to their libraries that would have previously required macros or static code generation. One interesting use cases is creating strongly typed access to external data sources. Type providers can be used to access JSON and XML webservices or even CSV files in a strongly typed way, so that user get auto completion on the data’s fields. Another uses is can also be used to offer integration to other languages that are not on the .NET platform. There is a type provider accessing the powerful statistical analysis language R, this type provider allows load R libraries, and get auto-completion on the functions they expose. In this talk we’ll see demos accessing various data sources and R language via type providers. Then we’ll look under the hood see what it takes to build a type provider. Robert Pickering	Workshop: event storming 101 "Event storming" is a very accessible analysis technique to gain a deeper understanding in your problem domain. The tools we use are post-its, markers for everyone and a vast amount of space. In this hands-on workshop you will learn how to gain deeper insights in an application domain in just a few short, playful sessions of about fifteen minutes. You will not only learn to make your problem space explicit, but you will also learn how to handle things like lack of knowledge or inconsistencies between domain experts. We will end the session with a few very simple tips and guidelines in case you would like to host your own event storming workshop. Tom Janssen & Jef Claes
11:30 - 12:15	Real World Roslyn Last month at the Build conference in San Francisco, Microsoft open sourced their new compilers for C# and VB: the Roslyn project. Those new compilers are completely managed, written in their respective languages, and comprise a full set of APIs to analyze and modify code. It's a completely new direction compared to the previous approach where the native compilers were complete blackboxes for developers outside of Microsoft. The benefits for the C# and VB teams are obvious: the compilers are easier to develop, maintain and improve. The benefits for writing developer tools are obvious as well: you have access to the exact same level of information the compiler has using a documented API. This session will be the opportunity to present how Roslyn can be used outside of those two very specific fields, and to imagine how in the future it could become a very central part of the .NET ecosystem. Jean-Baptiste Evain
12:15 - 13:45	Lunch (and open spaces, games, prizes)
13:45 - 14:30	Katana and Owin: a new lightweight Web server for .NET Let's have a look at Katana, the Microsoft implementation of the community driven OWIN specifications for a new web server, more modulare and lightweight, a la Node.js. Simone Chiaretta & Ugo Lattanzi	Monoids, Monoids Everywhere in your domains! [FR] (Discover the elegance of monoids for your domain models) You probably can't imagine that Monoids (not monads) are so simple that you can understand them in just a few minutes. But you probably don't imagine either that they can help you craft elegant and powerful domain models everyday. Through various examples, we will have a closer look at monoids used for domain modeling in a style that mixes the best of DDD and FP. Even in languages like Java or C#, this talk will influence your coding style forever! Cyrille Martraire
14:45 - 15:30	Event Sourcing, DDD and F# a match in heaven F# has proven very efficient to implement Domain Driven Design and Event Sourcing, using it in production for more that a year now. We will see how to craft a very clean Domain benefiting from the functional nature of Event Sourcing and the terseness of the language, and how to integrate with the Event Store. The presentation will also give insight on how to implement event sourcing with other languages, platforms and storages, no prior knowledge about F# or functional programming is required. Jeremy Chassaing	Refactoring your software architecture [FR] Most dev teams have a very simple conception of software architecture. They start with a database, a user interface, and add layers of (DRY) mess between the two. Then they have a performance problem so they add memcache and mongodb (Now we're webscale!). Months or years later, releasing new features in production gets harder and riskier: it's time for a rewrite. Let's use AnguNodeMvcDoop to solve all our maintainability issues! And the cycle starts over... In this talk we'll see that software architecture is not defined by the technologies you use but by the high level principles you set. We'll see what really matters to make your information system maintainable and how to get there progressively! Julien Lavigne Du Cadet
15:45 - 16:30	Common DDD pitfalls: mind the gap While DDD is becoming more and more popular, there are quite a few potential misinterpretations and malpractices floating around. These issues are time-consuming, and they induce a lot of frustrations and needless yak-shaving experiences. These pitfalls are plenty, ranging from higher level things (for example a lack of focus on the strategic part) to technical things (for example misinterpretations of the repository pattern), and even the surrounding area (for example errors made when"selling DDD" to your team members). By sharing this experience I hope to reduce the huge amount of time and effort people spend on "doing DDD wrong". Tom Janssens	Low-latency solutions in managed code [FR] For some years now, we have been seen here and there some weird guys trying to implement low-latency solutions in managed code (Java, C#). The thing is, they are not only weird: they are pretty good too. They actually managed to develop complex applications that run for days with almost constant response and processing time, very close to what we see in heavily optimized native apps. We are talking about people from Informatica, LMAX, Rapid Addition, etc. In this session we propose to give you some details about why, and how to actually achieve this in .NET. How to design, code and test your managed low-latency application. We'll talk about principles, techniques and tools that are now successfully used in this field, like mechanical sympathy, zero-alloc and GC-free programming Romain Verdier
16:45 - 17:30	Closing keynote TBD Greg Young
