nCrafts Bdx

Created by developers for developers, NewCrafts is an ephemeral learning ground for professional developers who care for quality code and bettering their practices

« I’m not a great programmer; I’m just a good programmer with great habits. »

Programming as a Way of Thinking

A conference that doesn’t affect the way you think about programming, is not worth attending!

Created by developers for developers, NewCrafts is an independent and international event on software development held annually in Paris since 2014.
Because we believe it is not enough for code to work, we wan't to challenge not only the way you develop but also how you perceive the profession and your craft.

For the first time, Bordeaux welcome a two days local edition with both english & french sessions.
First day will be a single track conference, while second day will be run as an open space unconference.

We provide place, coffee and speakers, so that you can take care of the rest.

Educational neurosciences, what can they teach us ?
Educational neurosciences question our beliefs, and make us wonder what do we know about apprenticeship patterns, with a little help from scientific results.

They deliver 3 main messages : 

  • equipped with biological plasticity, our brain can reconfigured itself during our whole life
  • Knowledge about how our nervous system is actually working can enhance our personal and collective choices (for exemple, lifestyle, or our relation to all kind of screens)
  • Let us all be co-researchers, so we can help all mankind
This conference will explore all this 3 messages by studying common neuromyths.

Pharo, a Live programming environment

In this session, you will discover why coding in Pharo, a language and IDE Smalltalk-inspired, is so fun! Let’s think of a language with a minimal syntax, where everything is an object you can interact with by sending it messages.

Pharo is a live programming environment: you can inspect any object with views dynamically adapted to the object kind, you can interact with the object and get an immediate feedback. Last but not least, you will get an amazing debugging experience: no more fear to debug an application.
Pharo debugger is your friend. You will see that Smalltalk, back to 80s, inspired a lot of languages like Java, Ruby, Objective-C but also encourages best coding practices like TDD.

After a brief introduction to the Pharo language, you will get immersed into a live Pharo coding session. To end the session, you will discover amazing projects that are coming to Pharo in a next future.

The systemic of the Liskov substitution principle

The Liskov Substitution Principle: the least known and most frequently violated of all S.O.L.I.D.!

Let’s explore together what it is, why you should care, how to detect violations, how to stop violating, what is co-variance and contra-variance (What is the In/Out of C#, the Super/Extends of Java, the +/- of Scala).

But above all: Let’s see that the essence of Liskov is the essence of Object Orientation itself: Systemics.

Let’s learn to see our codebase as a System.

From Front to Back: Homomorphic Event Sourcing

Event Sourcing is a way to structure a business domain model, where influences from the outside world are regarded as Commands ( “Buy a ticket for a concert”) that internally trigger Events which are the system’s response to the corresponding Commands ( “Concert ticket was bought by ...”).

At each point in time, the state of the system can be fully reconstructed by looking just at the Events. This approach, coupled with CQRS and other Domain-Driven Design techniques, has a number of advantages: It yields a clean separation of state, interactions and storage; it establishes a direct way to express business domain concepts in terms of interactions; it is composable...

On the other hand, events have always been at the core of User Interfaces, which typically consist of an event loop that pumps events from the underlying system and injects back requests to redraw parts of the GUI. Modern UI frameworks like React/Redux or Elm are actually built on this abstraction: In Elm, Commands trigger an effect on the system, and the resulting Events update the state.

This session proposes to fully embrace Event Sourcing in both front-end and back-end. It shows how to bridge the gap between both worlds by applying morphisms between the language of the front-end and the language of the back-end. We will demonstrate this integration on a small game built with a React UI and a Haskell backend, and in the process show how this approach fits nicely with Functional Programming languages.

All my team is using rust. HALP!

Something strange happened at Clever Cloud: everybody has started using rust, little by little. Many greenfield projects are using rust. That's not to say we've stopped using scala, java, or ruby (and even a bit of go and haskell). As a CTO, how do I keep complexity and language diversity in check? How do I choose which language to use for projects? Do I let others choose?

Refactoring mount doom, tackling legacy code

We’ve all had that nightmare where you are try to get to your destination, and keeping moving, trying different things, but for various reasons, you never arrive. Some refactorings are like that - you extract methods, name constants, increase readability… In short, you spend a lot of time cleaning up - but you never get to a good place with the code. In this talk, I will show you how to refactor for the right reasons and the right methods to use your time efficiently. Let’s make working with that code easier in the future.

The day after tomorrow: Let the machine do the coding

Programming means suffering - today. The programmer needs to do the typing herself (except for the trivial code snippets that Eclipse can bang out), the machine's job is to nag and reject when there's an error. In particular, a modern type system can be very good at pointing out errors, but the human still needs to tinker with the program to make it shut up. This is in spite of the fact that most of the domain knowledge is already contained in the type definitions and method signatures: Program by Design shows how this can work. Now, if we specify a little bit more, shouldn't the computer be able to write the code? The future of programming or just pipe dream? A new generation of programming languages and IDEs gradually turns this dream into reality: These tools are slowly becoming partners in software development. They make programming more fun, and can cut down dramatically on the error count. In the process, they liberate developers from implementing recurring patterns over and over. Developers can focus on the individual aspects of the software, on properly modelling the domain and on the user experience.

Discovering event storming

Let's explore a fictious business domain using the event storming approach, made famous by Alberto Brondolini.

13:40 - 17:30
Kebab kata: Fight the system making your code sad!

Try to create a code you will not consider "legacy". I'll play the role of your client and use around 20 techniques to make you fail. You will fail. We'll then discuss what techniques I have used, how they happen in real life, how to fight them in your project. All languages welcome. Bring your own laptop with your environment. We'll split into small teams.
