MH is a personal effort to build systems based on a single, almost arbitrary, abstraction: the device. The original idea was that having a system with a limited, but easily understandable interface would allow to build systems that are easy to grasp and fun to extend.

This talk will tell about the experience of designing MH, the lessons learned, errors made, and what using and playing with such system looks like.

Embracing containers and micro-services with their scaling model and resiliency is the new frontier in software packet processing.
This talk will describe the reasons, the challenges and opportunities of this trend.

DPDK revolutionized software packet processing initially for discrete appliances and then for Virtual Network Functions.
Containers and micro-services technologies are extensively used as a means to scale up and out in the Cloud.

Containers and micro-services now include Comms Service Providers among their advocates, and embracing these technologies with their scaling model and resiliency is the new frontier in software packet processing.
However there are challenges in decomposing Software Network Functions into Data-plane Micro-Services.

This talk will describe:-

1. The challenges of enabling robustness and scaling, while still meeting data-plane performance goals.
2. The use cases, the trends and the timelines.
3. The enabling work to date in DPDK and FD.io VPP, and the next steps.

The residential heating division of Bosch thermotechnology is developing products for domestic hot water
and central heating in homes. These products include an app (iOS and Android) connected smart room thermostat and
a control unit for controlling a boiler appliances.
During this presentation, we want to share our lessons learned by explaining our testing strategy and the usage
of robotframework.

Specifically we will share our story about:

• Our usage of robotframework to test the mobile apps we develop. Show framework architecture
  for combined on target and simulator testing. How to test on several different real phones.
• The testing of the internet connected room thermostat with robotframework. How
  to handle (stub, mock or fake) the different (radio) interfaces.
• How we setup robotframework to test the embedded software with accelerated time.
  Show the architecture of the embedded software and how we can run this on both target
  and PC platform. How the modelled system dynamics were used during testing.
• Do's and dont's when testing a product during development.

About the authors:

• Alex van de Schootbrugge is an embedded software engineer working on the smart room thermostat.

• Windel Bouwman is an embedded software engineer working on the control units for boiler appliances.

Cypher is a property graph query language that provides expressive and efficient querying of graph data. Originally designed and implemented within the Neo4j graph database, it is now being used by several industrial database products, as well as open-source and research projects.

Since 2015 Cypher has been an open, evolving language, with the aim of becoming a fully-specified standard with many independent implementations. We provide a brief introduction to Cypher, the property graph model and the openCypher project, and then describe extensions – either actively being developed or under discussion – which will be incorporated into Cypher in the near future. These include (i) making Cypher into a fully compositional graph query language, by supporting multiple graphs and allowing graphs to be returned from queries; (ii) allowing for more complex patterns (based on regular path queries) to be expressed; and (iii) allowing for different pattern matching semantics – homomorphism, relationship isomorphism (the current default) or node isomorphism – to be configured at a query-by-query level.

The purpose of my talk is to tell the BSD community about the work we are doing, and what we can do to help them. I will address the key areas we focus on and highlight the work we did in 2017, and why it was important to keeping FreeBSD relevant and innovative. I will have a Q&A session at the end, so attendees can ask questions about the Foundation, and what they'd like to see us working on in 2018. This will be a good opportunity to have a face-to-face dialogue with community members we don't normally get to talk to in person.

FrameRetrace is the first fully open-source graphics performance analysis tool for OpenGL on Linux platforms. It enables rapid experimentation with shaders, state, uniforms and experiments, to find and fix performance or rendering problems in a frame. This talk will describe the current state of FrameRetrace, and why it is a compelling tool for OpenGL application and driver developers. A demo of FrameRetrace will illustrate and fix a performance problem in the mesa driver.

In Linux 4.13, GPU performance counters were added to the kernel, dramatically expanding the information available to understand GPU performance bottlenecks on Intel platforms. FrameRetrace exposes these counters in a responsive UI, providing a detailed cost analysis for every aspect of a frame's rendering. The following live experiments allow a developer to alter the frame and immediately see the impact on both performance and rendering:

• shader editing and recompilation
• changes to GL state settings
• changes to uniforms values
• experiments (simple shader, disable render)

Because FrameRetrace is built on top of ApiTrace, it can analyze most OpenGL applications. It can also provide parallel analysis of the same frame on Windows and Linux platforms, to highlight driver differences. This key feature makes FrameRetrace especially powerful when enabling new hardware that has a well-supported driver for Windows. Hardware teams from AMD and Broadcom have expressed interest in FrameRetrace for enabling their platforms.

The current feature set of FrameRetrace is compelling, and Mesa driver team has already fixed many driver issues based on findings from the tool. I would like to encourage wider use of FrameRetrace, and solicit help in adding features -- especially support for AMD hardware.

Mozilla Open Source Support (MOSS) is Mozilla's program for supporting open source projects financially and with security audits. Find out about our successes so far, and how you can apply for help for your project.

There are 3 main tracks in MOSS - "Foundational Technology" for projects Mozilla already uses, "Mission Partners" for projects doing work in line with Mozilla's mission, and "Secure Open Source", where we provide professional code-read security audits for key pieces of open source software.

So if your software is used by Mozilla in any way (part of Firefox, deployed in our infra, used on desktops, or any other way you can think of), or if your project does something you think furthers Mozilla's mission (check the manifesto, and our current work and where we are focussed), and money would help you do what you do better or faster, you should find out about MOSS and consider applying. We don't accept applications directly for the Secure Open Source track, but you are welcome to come and make your case to the presenter as to why giving your project a free code-read security audit from a professional audit firm would make the world a better place.

So, come to the presentation to find out about our successes so far, our plans for the future, and how you can apply for help for your project.

As you'd expect, Red Hat IT has a very large Linux user base. For over a decade our associates have relied on Red Hat Directory Server (standard LDAP), MIT kerberos and some homegrown automation for most of their identity information and authentication. As we've grown overtime we have desired a more integrated and featureful solution. Red Hat IdM/FreeIPA is this solution.

This talk will go over what our old infrastructure was and what we are moving to. More importantly, it will cover all the snags we've hit along the way and what we did about them.

Declarative systems, like Kubernetes [1] are nice. Instead of forming the state of the system command-by-command, one just posts a set of declarative requirements. The system will try to adapt. While it easy to understand how to use such a system from the user perspective, it requires a complete rethinking for us engineers on how to integrate with such a system. Based on the experiences with extending Kubernetes for KubeVirt [2] with the Kubernetes-Go-SDK [3], this session gives a short and concise overview on what is required to implement declarative flows in general and particularly in Kubernetes. Real-world examples and pitfalls included.

The Open Source label was born in February 1998 as a new way to popularise free software for business adoption. OSI will celebrate its 20th Anniversary on February 3, 2018, during the opening day of FOSDEM 2018. The presentation will summarize the evolution of open source licences and the Open Source Definition (OSD) across two decades, explain why the concept of free open source software has grown in both relevance and popularity and explore trends for the third decade of open source.

Open source software is now ubiquitous, recognized across industries as a fundamental component to infrastructure, as well as a critical factor for driving innovation. Over the past twenty years, the OSI has worked to promote and protect open source software, development, and communities, championing software freedom in society through education, collaboration, and infrastructure, stewarding the Open Source Definition (OSD), and preventing abuse of the ideals and ethos inherent to the open source movement. The “open source” label was created at a strategy session held at the start of February 1998 in Mountain View, California. That same month, now almost twenty years ago, the OSI was founded as a general educational and advocacy organization to raise awareness and adoption for the application of free software in an open development process.
Some of the largest forces in business today — consumer-facing companies like Google and Facebook, business-facing companies like Salesforce and SUSE, companies outside the tech industry such as BMW, Capital One, and Zalando, even first-gen tech corporations like Microsoft and IBM — all increasingly depend on open source software. Governments too, including the European Union, France, India, the United Kingdom, the United States, and many others have discovered the benefits of open source software and development models. Successful collaborative development of software and infrastructure used by these organizations is enabled by the safe space created when they use their IP in new ways... to ensure an environment for co-creation where the four essential freedoms of software are guaranteed.
As open source adoption has expanded, we have seen changes in the assumptions surrounding licensing, governance and development of open source projects. We will document that evolution and look ahead to see what trends and pressures face the global free and open source software movement as it expands beyond ICT to wireless, distributed devices and beyond.
