One of the secret ingredients in many successful, big code bases is that they found a good level of abstraction. One helpful technique is to write declarative code: You describe "what" you want to do, but don't mix it with the "how". While this is not specific to Rust, the language and its ecosystem help us write declarative code. This talk wil ...…

In our new "Project Highlight" keynote format we selected an important, interesting and successful projects/initiatives and invite their leaders & contributors to talk about their work, experiences, and the things they have learned along the way to benefit the larger Rust community.In Rome Ashley Williams, Alan Kavishe and Lee Baillie will be p ...…

A conflict-free replicated data type (CRDT) is a data structure that can be replicated, each replica can be updated independently and it is always mathematically possible to merge the replicas back without conflicts. The simplest CRDT is an _append only_ Set, where the _merge_ is the Set union, building upon this idea we can compose more comple ...…

Efficient FFI bindings are one of the core features of Rust; however dereferencing raw pointers, conversion between Rust and C types, memory allocation, ..., all could possibly go wrong in FFI code and undermine the memory safety guarantee of Rust. The Rustonomicon and a few previous talks at RustFest discuss the topic of Rust FFI; but overlook ...…

If it's a mystery what actually goes on when you do a 'cargo run', then this talk is for you. It explores the sequence of steps taken to get to a working executable, from high-level code, to machine code, and what happens in-between. We'll do a simple example and see what each representation looks like, while touching on the steps in-between. I ...…

Lately as a hobby I am participating to robotic competitions where autonomous robots fight according to various rules (usually speed races or Sumo fights). Lately I am putting Rust into every robot I program, from bare metal (arduino-like AVR and ARM Cortex-M), to Linux on higher level boards (Raspberry PI, Beaglebone), and even on a real time ...…

OpenPGP is best known for its use in email encryption. But, OpenPGP is, perhaps more importantly, used to secure software updates, sign commits, and protect backups.Historically, OpenPGP has been hard for both end-users and developers to use--we know, we actually worked on GnuPG! In Sequoia, we are trying to change that. Sequoia is a new OpenPG ...…

On the eve of Rust 2018, we have so much to celebrate! From the core language to tools to community outreach to adoption, the Rust project has made enormous strides. But with success comes new challenges. Looking ahead to the next Edition of Rust, this keynote will lay out some of these challenges along three dimensions: Stakeholders, Governanc ...…

The magical thing about Rust is its ability to remove the fear of learning new things. My journey with Rust has led me to the world of hardware emulators - specifically old gaming machines from the 80s and 90s. Join me as we explore what it takes to implement a fully working Game Boy emulator. We'll take a look at the ins and outs of this 30 ye ...…

This talk will focus on some of the challenges encountered while working on integrating SpiderMonkey JavaScript engine with the Servo web browser engine (written in C++ and Rust, respectively). We will explore how Rust's rich type system made it possible to enforce many Servo–SpiderMonkey interface rules and safety considerations at compile tim ...…

Rust seems like a perfect candidate for scientific computing, building fast and efficient algorithms for scientific research and data science, but why isn't it there yet? Explore the state of scientific computing in Rust, from where it shines to it falls down, to where we can improve as a community, and learn about Rust in an area that has so m ...…

Everybody uses it, the most of them love it. But who really understands SSH security measures?Therefore i will revive these. Starting at publickey security to protocol security.Nowadays, there is often a lack of real understanding of protocols and tools. That is just natural due to the complexitiy of modern systems and the huge amount of parts ...…

The next movement in network programmability is the data plane itself. Beyond APIs to the control plane, a domain specific language for data plane programming is emerging as a powerful tool in reasoning about packet networks.Programming network devices has stopped being a responsibility exclusive to the vendors selling them. Today, with control ...…

Resource Public Key Infrastructure (RPKI) is a specialised public key infrastructure (PKI) framework designed to secure the Internet's Border Gateway Protocol (BGP) routing infrastructure. In recent months there has been a lot of traction around this technology, with several organisations ranging from small Dutch hosting providers to one of the ...…

Renumbering of IPv6 clients using DHCPv6 servers without a flag day is highly desired. RFC3315bis describes Reconfiguration mechanism to dynamically renumber IPv6 addresses. Commercially available DHCPv6 servers and clients do not support Reconfiguration feature as specified in RFC3315bis. This talk discusses reconfiguration feature and its imp ...…

In a typical Openstack or KVM deployment scenarios an overlay network is built between hypervisors to provide an L2 domain over an IP-fabric. An overlay network allows (live) migration of VMs and multi-tenancy in infrastructure. Unfortunately, with typical setups, the physical underlay network infrastructure is ignored.This talk will discuss a ...…

PeeringDB has been around since 14 years. And an entry in PeeringDB is a must have if you want to interconnect with other networks. There is no other DB where you have all the information about networks, Internet Exchange Points and Facilities/Colocation at one place and nicely interlinked.As PeeringDB is so important an Seattle (US) based asso ...…

A server farm in a single broadcast domain should use a shortest way to the next router minimizing inter-switch traffic. Faking Neighbor Discovery messages direct each server to the right router.Application servers often need to communicate to each other in a common layer2 area. If such an area spans multiple networking devices, the data flow i ...…

Is it not contradictory to use proprietary software as a cooperative? Is the production of free software through unpaid work, which may then be used by profit-oriented companies such as Google, not a reinforced form of labour exploitation?
