RustFest Barcelona 2019 Workshops

RustBridge is an all-day workshop focused on getting underrepresented people with a background in another programming language to learn Rust and join the community. In this workshop we’ll get you up and running with a Rust development environment, introduce you to Rust syntax and programming concepts, and work together to build a small website that you can personalize, extend, and share!

The rust ecosystem is missing a performant crate to serve GraphQL APIs generated from existing database schemes. Wundergraph fills this niche by utilizing Diesel and Juniper to provide a performant way to serve a database schema as a GraphQL API.

As part of this workshop we will

• explore basic Diesel usage
• learn how Diesel works internally
• look into basic Wundergraph usage
• and learn how to build complex abstractions like Wundergraph

Each step will be augmented with practical hands-on coding exercises.

If you like to see advanced uses of Rust’s trait system, or if you’re interested in how we managed to write a high-performance GraphQL server library, this workshop is for you.

In this workshop we will develop a small command-line application that acts as a WebRTC peer and can share audio/video streams with a web browser or another instance of the application.

Technology-wise we’ll use GStreamer for the multimedia aspects and Tokio/websocket for the networking aspects, and we’ll make use of async/await.

Basic Rust knowledge is a requirement for this workshop and participants should bring a laptop (ideally with webcam/mic), running Linux, macOS or Windows, or pair with another participant on their laptop.

In 2019, there’s Kubernetes everywhere, and developers have become used to just dropping a container to get our apps running, then quickly forgetting them until something breaks again. The convenience is hard to question. But how do we know what happens in the meantime? This workshop will introduce the basics of modern Linux monitoring using Rust and eBPF.

You will learn how to write eBPF modules that run inside the kernel to intercept syscalls with Kprobes, filter and monitor network traffic using XDP, and copy packets into user space using socket filters.

We’ll use InGRAINd, Red Sift’s eBPF platform that lets you write all the code in Rust, and compile everything into a single binary, and pop it onto a server without any special setup.

Bring your own workload, containers, VMs, cluster, mainframe, or Raspberry Pi.

On Sunday this workshop will repeat. If you haven’t been before, this is your chance to attend. If you joined on Saturday and want to continue to work with Rust and eBPF on your own, you are invited to come as well.

The ndarray ecosystem provides the basic building blocks to write scientific computing software in Rust: we will go through the main features, the data ownership model and other fundamental concepts required to properly leverage the strength of this suite of crates.

Most machine learning techniques, once you get to the nitty gritty implementation details, boil down to a bunch of matrix multiplications and linear algebra algorithms, with a sprinkle of statistics. We will implement from scratch some machine learning routines as a hands-on introduction to ndarray and its ecosystem.

Creative coding is a way of looking at programming as a tool for creative expression. One of the beauties of creative coding is the potential to express ourselves in a wide variety of domains. Nannou aims to give equal priority and easy access to a full suite of creative I/O including graphics, multi-windowing, audio, LASERs, lighting and more.

Attendees will get an introduction to creative coding through nannou and the opportunity to use nannou to experiment with each of the aforementioned domains in a guided, relaxed and playful setting.

This workshop tries to gather feedback and opinions on what people would like to have changed/improved/added in rustdoc and Rust documentation more generally, but also discussing about some old (and “famous”) issues to get some new insights.

Furthermore, this can be used as a discussion ground about good practices when writing Rust documentation and present some useful but not very well known rustdoc features.

The idea behind it is trying to be able to connect to documentation users as well as writers and try to hear their needs in person.

Rust is a great choice for embedded development! It combines high-level abstractions with low-level control, safety with performance. In this workshop, you will learn embedded development on a microcontroller, using Rust. We’ll teach the basics, talk about pitfalls, and provide an environment for experimentation.

Experience with embedded development is not required, but basic Rust experience would be helpful. Every participant will be provided with a LPC845-BRK development board, free of charge and for them to keep.

Find installation instructions on Hanno’s blog.

Ever seen sketchnotes (visual notes of technical content) at a conference, and wished you could communicate as clearly, and quickly?

We’ll let you in on a secret - drawing is a teachable skill, just like writing code is.

We’ll start this workshop with fun introductory exercises we’ve refined at conference workshops this year, to help you build some confidence. Materials will be provided.

Next we’ll show you how you can use visual techniques to help with discussions in daily work situations, summarise subjects you’re learning, or capture the key ideas from talks.

You’ll leave with new confidence and skills you can use the same day!

An ad-hoc space to present and discuss your latest research and experiments with Rust.

What are you working on? What’s your crate of the month? Any RFC that’s noteworthy? A new cool design pattern you recently learned and applied in your own codebase?

You are encouraged to bring a lightning talk, a discussion started or your code problem. All attendees will be invited to both ask for a topic to be covered, and present on any topic of interest to the group. Participation is voluntary, of course.

Ever wondered how to make games using Rust? New to Rust and hoping to use making a game as a good way to familiarize yourself with the language? Wanna have some fun and do some coding along the way?

Yes! Same here! To all the above!

Let’s make a co-operative game featuring our friend the 🦀 collecting treats at the beach, using Rust and ggez!

Nature has beautiful forms: from the crescent waves on the ocean to the beautiful wings of certain butterflies; from the stripes and spots of animals to the branching and weaving of plants and trees. All these patterns seem intricate and complex. Often they can be modeled in a simple and effective way. Sometimes this model lets you learn something about nature.

In this workshop, we will explore Lindenmayer systems, or L-systems. These systems allow you to model various natural forms such as plants and it offers a playground for certain type of fractals. So let’s explore your favorite natural forms.
