Open Source Bridge

Imagine a place where Ruby meets Music, its called MAGIC LAND. Music is not a lot different from programming. In this talk we will see how. I will talk about this amazing piece of open-source software called SonicPi. SonicPi is a new kind of musical instrument. Think about it, you write code to make music. And it gets even better, code is written in a ruby DSL. Also I will talk about notes, samples, synth and other musical things SonicPi lets us do it. Don't worry if do not get these terms. When I started, I did not either. But at the end of the talk, you will know how to make music.

How robust is the filtering of your API? Let's delve into how a string of text can become a set of instructions to the API on exactly what records should be returned.

In this talk, we discuss the internal working of the translators and key architectural components of GlusterFS. Along with that, one can gain a deep insight about the enforcement techniques, few challenges, the current state of GlusterFS, undergoing researches and look forward to how the Gluster community may address those challenges.

Trusted Analytics Platform (TAP) is an open source software, optimized for performance and security, that accelerates the creation of cloud-native applications driven by Big Data Analytics. This talk uses TAP to detect anomalies in earthquake data and indicate any outliers on real time data. http://trustedanalytics.github.io/

Trusted Analytics Platform (TAP) is an open source software, optimized for performance and security, that accelerates the creation of cloud-native applications driven by Big Data Analytics. This talk uses TAP to address two very common questions arising in data science– ‘Which model best fits my data?’ and ‘How do I find the optimal parameters for my models?’ http://trustedanalytics.github.io/

The team building community around a book called The Open Organization wanted to see how social media could enhance our efforts. We investigated and successfully used Twitter chats as a way to continue conversation and dialog around what it means to be an open leader. Now it's time to share what we've learned so you can do the same thing for your community.

We will explore how we can utilize webvr to build amazing VR experience right into everyone's pocket, using their mobile phones they use right now. No need for expensive or closed source tools or solutions. Utilize the mobile phone with cardboard and uisng just javascript and html to build VR world. How using api's of webvr and Aframe we game developers and UI builders can build awesome experience.

Join this interactive session connecting what we know about face-to-face collaboration and how and why it works with what online dialog, games, berry-picking, wayfinding and other large scale activities can accomplish.

This talk will explore the state of open source marketing software, and the viability of using it to run a marketing department.

There is a secret recipe for successful civic hacking. As a Code for America brigade captain for over three years, organizer of numerous civic tech events and hackathons, and authoring a book about open source, open government, and open data, I have a tremendous amount of knowledge to share about civic hacking.

Many people create projects with amazing technical prowess, only to see it fail to gain traction. We wonder "I thought this was clearly the best solution, why aren't people using it? Did I miss some bugs? Is it too slow? What went wrong?" The answer usually isn't technical, it's documentation or community related. This talk will teach you all the non-technical things your project needs to gain traction.

Copyleft, and the GPL in particular, are under threat. The treacherous political climate of for-profit open source cooption has changed the nature of our community. Can copyleft continue to be an effective tool to defend software freedom, and if so, how?

The desktop application market has long languished. Even today there is no way to understand the strength of the GNU/Linux desktop application market. This talk will focus on creating a measurable desktop market by focusing on changing the application distribution model using GNOME xdg-app.

Learn how the browser renders webpages, how to write better css, and how to monitor front end performance in Chrome.

Figuring out what to keep and what to get rid of is an important task for librarians, and the armada of statistics kept is supposed to help. Getting things to mesh just right, however, sometimes requires custom code. I'll show you my solution (in Ruby) and the reasons why I created it.

The right model for access controls will convert unruly actors into well behaved users. When you consider access controls as relationships between players, you discover a deeper narrative in your data.

Despite the media attention given to the diversity in tech problem, many technology practitioners don't see how a lack of diversity affects their daily life. So, it is not surprising that they neither understand the magnitude of the problem nor how they can fix it. However, the principles and language of debugging, something technology practitioners understand well, can be used to help them understand diversity and their role in solving the problem. So, technologists already have a set of terms that they can use to tackle diversity. They just need to know how to apply those terms in order to effect positive change. These terms are expected behavior, tracing, refactoring, and sample code.

The Clear Linux Project has some really nifty, fully open source innovations that can help anyone build and maintain unique distros of their own.

Devopracy is an open source project to build a disposable, portable cloud for civic engagement events and virtual democracies. We'll examine these use cases with consideration for security, maintainability, and code quality. There's a companion workshop on how to deploy the cloud and deploy an application onto it.

When designing a reliable solution with lots of moving parts, it's important to look not just into code but in-between code - more at the integration parts of the overall system. In this intense talk you will learn about the variety of real-world important aspects to take into account architecting a flexible microservices based solution. Some of the valuable aspects are environment choices, infrastructure planning, preparation and automation, separation of solution parts into independently deployable services, service discovery, replication, resiliency and many more. You will explore into the practical architecture of Kubernetes, see how to create and configure Kubernetes cluster on AWS and GCE, create and prepare containerized services to be deployed into the cluster.

There are many types of open source databases and data analysis tools from which to choose today. Should you use a relational database? How about a key-value store? Maybe a document database? Or is a graph database the right fit for your project? What about polyglot persistence? Help!

Contributing to open source is rewarding in terms of the satisfactions you get while you help the open source community to grow as well as the new things that you get to learn. If you go on discussing about contributing to open source most of them find it intimidating. Most of them are scared of contributing to open source projects. Most of them think that it is too tough to get in, too tough to get started and they won’t be able to do it. There are a lot of myths about the difficulty level of getting started with contributing to open source. With this talk I would like to break the myths and tell the truths around them.

The principles behind building reliable distributed systems and gracefully managing changes in them turn out to look a lot like the principles behind building psychologically safe communities. In this talk, I'll explain some of the basic principles behind site reliability engineering and how they relate to feminist and social justice ideas. This talk assumes no prior knowledge of site reliability engineering.

This talk will look at how we can improve our users experience at any scale through performance optimizations at every layer of the stack, from backend to browser.

Miscommunication, wasted time, hurt feelings: real dangers when communicating with strangers online. As FOSS maintainers and contributors, let's try documenting our communication guidelines the same way we document our code style guidelines.

How do you decide whether a new programming paradigm is worth learning or not? I ask myself a simple question: can I use it to make games in a simple way? Learning by playing is super fun. Allow me to take you on a thrilling journey to explore functional programming through JavaScript games. Let us dive deep into functional features that will help us approach complex problems from new directions and write bulletproof code.

In many open source communities, privilege is rarely discussed. While it is not an easy topic to talk about, it is an important subject to explore if we want to make sure open source is truly open to everyone. After exploring sources of privilege and learning strategies to deal with it, we can all be better equipped to take action to improve our open source communities for the long run.

If failure is inevitable, why aren't we taught how to cope with it? In this talk I outline 10 types of failure to avoid and detail a framework for navigating recovery from failures large and small.

In 2001, Chou et al. published a study of common faults in Linux versions 1.0 through 2.4.1. They used a static analyzer to get the results. In 2014, Palix et al. extended this work to cover the 2.6.x versions of the Linux Kernel [1]. They found that the number of common faults decreased from the previous study results, implying better code quality in 2.6.x, but was still very high. This talk will report on my work on applying the same analysis to the Linux 3.x versions. The studied period in particular includes the zero-day build testing service in 2012.

Have you ever tried to extract a relationship among the data that your documents carry? Sometimes a document-oriented model does not provide us with an appropriate structure to collect how the data is related and we need a graph. Manual replication from MongoDB to Neo4j may be painful to be done. This talk will present a tool called neo4j-doc-manager (written in Python, based on mongo-connector project!), that allows you to grab MongoDB events and mirror them to any other database.

- 3 Secrets to Win at Organizing for Higher Performance

It's all too easy assume that your web or mobile app will run on a fast and reliable network with great coverage. The reality for your app's users, though, is often a slow and unreliable network with spotty coverage. What happens when the network doesn't work, or when the device is in airplane mode? You get unhappy, frustrated users. Building on the principles of mobile first, offline first is an approach to application design in which a web, mobile, desktop, or Internet of Things (IoT) application is built for offline usage first and is then progressively enhanced to take advantage of network connectivity when available.

Having a successful open-source project is more than putting your code on Github.

Why pay for always-on relational database service when you can deploy it yourself so easily? This demo-heavy talk will show off a deceptively simple high availability stack for PostgreSQL, using Docker, Etcd, Kubernetes, Patroni and Atomic.

Sometimes the tech community can feel like it is without soul so Hackers & Hearthstone was created to focus on the cool things people are doing within the technology world.

Clonezilla is popular for system deployment. However, there are some limitations. E.g. the destination partition must be equal or larger than the source one, the image can not be explored, etc. So any workarounds for them? Besides, are there any tips available to save system administrator's time? In this talk we will describe and demonstrate the workarounds about breaking the limitations and the tips to save time in system administration.

It's possible to do Support work while knowing absolutely nothing about the underlying architecture. Support doesn't necessarily know why the product works, or even what language it's written in. It can be super tempting for an engineer to think that well, if these support people really had the competence and capacity to understand how the thing worked under the hood, then they'd be engineers and not mere support people, but that's a bad trap to fall into. Sometimes Support people are engineers in their own right, but a Support person with no computer science training can be an expert on the user interaction surfaces of the product and reproduce a result that has been baffling the engineers, even with no knowledge of the mechanism by which the bug is happening. It's helpful to give Support enough information about the architecture to have a better starting point for asking the user for details and trying approaches to replicate the problem. It can be tempting for Support to think that any given member of Engineering understands the entire breadth, depth, complexity, and interconnectedness of the entire product simultaneously at any given time, but this is a trap! A good amount of time Engineering has no clue in the slightest about what is going on in another branch of the product, and in a sufficiently complex codebase, there can be millions of lines of code that a single particular engineer has never touched or even heard of. Or it's been long enough since they worked on that part of it that they would have to take several hours of very hard study in order to figure out what's going on. In particular, sometimes in a bug report, Engineering can say "Okay, I see what *part* of the code the user is causing to fire, but I haven't the FOGGIEST idea how the customer actually got that to happen." It's very important for Support to list out every single step (even the ones that seem obvious) that leads to the error occurring.

In 2009, Oh My Zsh was released. It's since become a popular open source tool used by developers around the world. Let's walk through how a really small idea turned into a big project.

Being a great developer is much more than technical know-how. Empathy, communication, and reason are at least as important, but are undervalued in our industry. We'll examine the impact these skills can have and how to apply them to our work.

Go behind the scenes at Opensource.com to learn how we are building a community and creating the world's premier open source story telling platform.

It is necessary a waste that we seldom make the most of free resources online. We spend a lot of budget buying the software which is replaceable and deal with problems in an ineffective way. That is why we start this project to help others in an efficient way.

The goal of this working group strikes deep at the heart of problems in open source software. We hear the stories of contentious and dramatic flare-ups, but not the day to day work people do to make things better. Come learn what it's like and what it takes to make a difference in OSS culture.

The OpenStack Infrastructure team uses an infrastructure-as-code approach to running an OpenStack cloud that supports its automated software testing infrastructure. This talk will discuss the challenges of administering a cloud in the open and cover the tools and technologies we use to accomplish it.

Growing concerns of media preservation mean a surge of new digital libraries. However, digital preservation is more than just photos and video; it's also interactive software: art creating new art. We will explore the problem of preserving software; past, present, and future; and why it is hard.

Apache CouchDB is a document database featuring an HTTP API, JSON documents, and peer-to-peer replication. Take a tour of the upcoming features and improvements in Apache CouchDB 2.0 including clustering capabilities for horizontal scalability and a declarative MongoDB-style ad hoc querying system.

This talk will discuss High Performance Computing and Lustre - an open source parallel file system. We'll discuss scaling challenges and how open source software is being developed to address them.

CoreOS rkt is a secure, modular execution engine for app containers. It was designed to reflect the lessons of running container cluster infrastructure at scale and is released under the Apache license. Written in Go, rkt implements container isolation through a flexible and interchangeable set of “stages,” providing multiple execution regimes for a container image. At rkt’s core is a command line utility that does not invoke a long-running daemon process, making app container lifecycle management simpler and allowing loosely-coupled integrations with service management and orchestration systems like systemd and Kubernetes.

Is your app flooded with incoming data, requiring ever growing herds of unicorns or pumas to keep up? Ever wished your background job queue was more resilient, or that you could choose to reprocess the queue after the fact?

HTTP is the fabric of the web and the growing API economy. Whether you're building a backend or a frontend application, creating an API, or consuming an API, it’s helpful to understand the basics of HTTP. Topics covered will include HTTP methods, request headers, request URIs, response status codes, response headers, resource representations, authentication, content negotiation, and caching.

In this presentation I will discuss midi, the lets get loaded framework, the open source tools used to implement it and demonstrate its use on the arduino platform.

Learn how difficult it can be to do emoji right and what you can do to preserve the message and emotions of your users. If you take user input, you owe it to the internet to attend this talk.

An autonomous car is driving down a single-lane road carved out of a cliff. Unexpectedly, a child runs in front the car chasing a ball, and trips. The car cannot stop in time to avoid a fatal collision, but it can sacrifice itself and its passenger by driving off the cliff. Should it? And if so, would you buy such a car?

Despite all the attention and buzz, Machine learning(ML) is woefully overlooked in the community of free and open source technology. In this presentation, I will examine the still prevalent proprietary legacy of ML, introduce the current open source stack of ML development and applications, and evaluate new proprietary attempts entering ML. Then, I will share with you the strategy recipes that we may need, in a battle to keep the booming field of ML free and open source.

I first knowingly witnessed the "Maker Movement" in 2010, heeded its siren call by joining the MIT Media Lab in 2011, and became disillusioned later that year. But I've been stubbornly making--and critiquing the notions of Making--ever since.

"A distributed system is one in which the failure of a computer you didn't even know existed can render your own computer unusable" (c) Leslie. As an end goal of the talk, we will create the Cassandra database cluster on Docker from scratch and build a cross platform solution to interact with it. To do that we should do a few things first: Understand what is Cassandra and why in the world we need it Talk about the data model for the demo I will show you how to create a Cassandra cluster (which will consist of 3 nodes, for speed of the talk) And how to create it fast and modular, that’s why we will use Docker ...

OSBridge is one of the best conferences I know to hobnob with talent in DevOps, Systems, and Infrastructure. This is an advanced talk on development environments for distributed systems programming. Let's get down with git, and automate all the things.

In this talk I'll cover how the team (more about the team in the talk) broke the barriers of .NET to integrate with Kafka, Storm, and Zookeeper to build a streaming distributed system.

What can you do when someone submits a bad patch to your project? To begin, we have to understand why people hunger to contribute code: they're fans. You hurt fans' feelings when you reject their patches, but you hurt your project if you accept them. You can get out of this bind! Give your fans other ways to be recognized. Showcase their plugins in your project’s wiki, or rewrite their patches while giving them credit, or feature their related projects on your site.

We'll run a few of the popular open source GIS software apps through some head to head exercises to see which ones can do what needs to be done.

Blogging is a great way for developers to share with the community the kind of things they've been learning and working on. By keeping a regularly updated blog, we force ourselves to continually evaluate the things we're learning, while sharing these ideas with the community at large.

Open Source is one of the foundation pillars of our industry. You probably use the power of open source software every day: in the code you write, the tools you build with, the servers you deploy to. But perhaps it’s not quite the stable foundation we were hoping for? This talk will cover the various strengths and weaknesses of both open source and our reliance upon it, so we can trade in our assumptions for a greater awareness of the issues. Then together, we can find a path towards a more sustainable open source ecosystem.

Have you ever noticed that many situations could it be expressed with a graph? Graphs are not only a boring subject into College, they can be really useful in many situations. This talk will show you some graph modelling with a nice graph database written mostly in Java: Neo4j. Through examples, we will see a little bit about graph theory, a quick introduction to Neo4j architecture, a handful tool called Cypher, non-trivial modelling and use cases.

What is oVirt? Why do we need shared storage management in virtualized environment? How can we manage it safely?

Your Ruby app is in production, but something isn’t quite right. It worked locally, it passed CI… why’s the running app acting weird?

Trusted Analytics Platform (TAP) is an open source software, optimized for performance and security, that accelerates the creation of cloud-native applications driven by Big Data Analytics. This talk aims to demonstrate how the Trusted Analytics Platform can be used to make real-time wellness recommendation using live data from your activity tracker. http://trustedanalytics.github.io/

Your Python program is too slow, and you need to optimize it. Where do you start? With the right tools, you can optimize your code where it counts. With the Python profiler “Yappi” we’ll learn how to find the maximum performance wins with minimum effort.

Do you remember how awesome it was to use Ruby on Rails' database migrations?

So, you think you're a full-stack developer? Let's extend that to the database, for a true full-stack experience!

The Supreme Court's ruling in the landmark Alice vs. CLS Bank case has finally given the lower courts some tools they could use to overturn obvious and vague patents, particularly frivolous patents on software. But we haven't won, because bogus patent suits are still being filed. This talk is for anyone who is wondering what the recent decisions mean for small and mid-size entities, how international treaties can impact local policy and what can be done to improve the situation.

Learn about survival analysis in Apache Spark and some questions it can help answer. For instance, what proportion of individuals can be affected by a phenomenon, at what rate will they be affected, how certain events affect the probability of survival. http://trustedanalytics.github.io/

What if U.S. federal agencies decided to reuse and contribute to open source software projects built by other agencies, since agencies often have similar technology problems to solve? And what if they hired technical writers with open source community experience to write documentation for these projects? That would be pretty cool. Also, that’s my work. I'm part of 18F, a digital services consulting team within and for the federal government, and all of our work is open source.

When you are trying to transition into tech, it helps to be part of an open source community that welcomes people from all types of backgrounds and experience-levels. If you are a beginner programmer and underprivileged, the search for the right tech community can be a daunting experience. You may be systematically excluded from participating in some communities by gatekeepers. As a programmer who comes from a marginalised community, allow me to share with you the story of how I found a programming community that welcomed and helped me to overcome the high barrier to entry in tech. This talk aims to encourage everyone to do their bit to create inviting communities for the underprivileged.

The Open Source Geospatial Foundation (OSGeo) has a stable of applications and technologies to make your mapping effective and fun. We'll explore some of the most popular apps.

With the growth of open source comes the need for more conferences, meetups and hackathons – you name it! These events give community members the opportunity to interact face-to-face to solve problems, come up with new ideas, or even just to chat and get to know each other better. But, the question is – how do we get developers, users and contributors from open source communities to these events?

How community triumphed over a corporation, a fun and educational talk on the back story of the GNOME trademark battle.

In November 2015, Wikimedia communities across Asia and the world set off on what would become one of the biggest online Wikipedia edit-a-thons ever: the Wikipedia Asian Month (WAM). Managing such a huge project though, especially with people from all over the world participating, is a big challenge. This presentation looks at how we did it, what we're doing now, and how your collaboration, online project or community can benefit from our experiences.

Non-centroid clustering increasingly is seeing need in data analytics as more complex models arise. Latent Dirichlet Allocation (LDA) is one such solution to a clustering problem known as topic modeling. In this talk we discuss what topic modeling is, why conventional techniques don't yield useful results and how LDA solves this issue.

The primary reason I was able to make career pivots at Intel was due to my connections to the Women at Intel network. Through this network I was referred to career counselors, business contacts, and the technical experts I needed to move my career ahead. As an FTM, my inbox is still filled with opportunities from women in tech groups, but now when I see these emails I wonder if I will be welcomed or not. A recent email I received said specifically "if you are female please attend." As a person who now identifies as male, I find that my connection to the community that supported me for the entirety of my career is now becoming tenuous.

I built my first Twitter bot in Node js to help automate a task: giving advice to people interested in being vegan. Simple enough! But even simple bots require love, maintenance, and moderation, to keep them useful, and more importantly, positive! How do you design and code a bot to engage with people in a way that maximizes positive interactions, and minimizes negative ones? I'll tell you what I did.

Global trade wouldn’t be as efficient without the invention - and standardization - of shipping containers. Standardized containers have globalized our economy across the shipping industry in a way that wouldn’t have been possible otherwise. What can this earlier standardization effort teach us about the tools and systems we’re building today? What are the struggles of our digital age? How are the struggles of shipping goods in 1950s similar to our content struggles now - and how can we move forward?

Iannis Xenakis passed away on February 4, 2001. When he arrived in Heaven, he sought out his mentor, Olivier Messiaen. Messiaen said, “Iannis, there’s someone here I want you to meet.” The two walked over to a small sidewalk cafe, and there sat Harry Partch. And so from this fanciful meeting in Heaven, “When Harry Met Iannis” was born. Now I'm not a carpenter like Partch was, and I don't have access to conductors or orchestras like Xenakis did, so I'll have to synthesize instruments and performers. The software that makes this possible is an open-source language called ChucK. I'll talk a bit about the Partch music theory, Xenakis' use of game theory and the ChucK language. But mostly, this talk is about the music and not the tools that made it. And you'll be the first to hear "When Harry Met Iannis 2016" in its entirety.

Many people say that achieving and maintaining 100% test coverage is too hard, too time consuming, or too fragile. But I'll argue that whether you consider yourself a craftsman or an engineer, you shouldn't accept anything less.

How to gain more support by decolonizing your projects by deconstructing networking with activists in Tribal Communities and other Environmental Justice groups...

Open source is an incredibly powerful engine for great software, but not so much for making money. Or so they say.
