PolyConf is a three-day, single track, multi-disciplinary conference on advanced
technologies
for programmers interested in polyglot approach to software development.
#polyconf was a best conference I've attended for a long, long time. Definitely plan to get back next year.
:)
@asolovyov
PolyConf is not focused on any particular language or area of technology. Our mission is to promote polyglot approach to software development and foster cross-pollination between various technologies and their communities.

This talk will present an experience report on the use of Clojure at Braintree. Primarily a Ruby shop, this talk will discuss why Braintree chose to use Clojure in the development of a real-time data pipeline, what we have learnt in doing so, and how those lessons are shaping future projects at Braintree.
What do Clojure, Java, Scala, and Ruby all have in common? They can run on the JVM. Today going polyglot is easier then ever!
In this talk we're going to learn why it's important to use the best programming language for the job and how to start doing so. By using the polyglot approach, your projects will be more flexible to change, simpler to test, easier to deploy, and understandable to developers with any programming background. Simple actions you can take to increase the versatility of your programming toolbox and finally get paid for writing code in your latest beloved language."
JSON or XML? Or maybe something else? I will explore the lesser-known areas of data echange formats including ASN.1, Google's Protocol Buffers, Apache Thrift and others.
It's not only programming languages that have their polyglots, databases too. In this talk I would like to explore the options we have when developing applications, considerations we should make and share several key points from my past where I made the correct or incorrect choice.
In fact, the talk will depend on the audience... After a short survey we will decide what AngularJS topic to address. Whether it be live-coding an application from scratch, showing JavaScript tools supporting development (Gulp/Bower/Karma) or demystifying directives, you will not get bored :)
TBA
The Cactus framework is a modular environment for parallel high performance computing. It allows development in the high performance language of choice: C, C++, F77, F90, and even OpenCL/CUDA, all while making use of existing components (called "thorns") and other standard high performance computing technology in a language independent manner. In this talk I introduce the Cactus framework with some examples of its use in computational general relativity to simulate black holes, neutron stars and more.
Programmers often write procedures or methods that model mathematical functions. These functions clearly distinguish between input arguments and output values. In contrast, relational programming treats programs as mathematical relations, eliminating the distinction between input and output. miniKanren is an embedded domain specific language for constraint logic programming, designed for writing interpreters, type inferencers, theorem provers, and other interesting programs as relations. We will explore the extremely interesting and surprising behavior of these relational programs, and consider how this approach to programming might be made more practical in the future.
TBA
What if you have some code already written in Ruby, and some other code written in Java, and they needed to run together and communicate with each other? JRuby makes that happen by enabling Ruby applications to run on a JVM. In this talk I will explain how you can make your Ruby on Rails application run on a JVM, what are the pros and cons of that, and the various techniques to make your Ruby and Java code talk to each other.
In this talk I dig into the depths of my programming library Cello - a fun experiment to see what C looks like when pushed to it's limits. I'll cover how Cello works internally, some of the cuter tricks used to make it look and feel so different, what is in store for future versions of Cello, and why it is important to push languages to their boundaries.
WebSockets are a modern protocol designed by Google for real-time data exchange between a web-browser client and a server. We're going to talk about some details of how the protocol works, looking for insights about protocol design.
Time Series have an amazing potential for Querying, Parallelisation and Query Composition, because of the nature of the Data itself, this is exactly why general-purpose stores won't ever be the best fit for Time Series data.
Continuum, a Time Series store was built keeping the key features of Time Series data in mind. State-of-art Algebraic structures, can be used to build flexible and composite Query API, Compact data structures can be used to save up space and reduce deserialisation effort while reading data from DB.
An adventure of building a Modern Time Series database in C + Haskell, with ClojureScript front-end, that brings the visibility of everything going on in your system on a whole new level.
Most complex distributed systems happen by accident, as an evolution of a design initially thought simple. Not everyone wants to be involved in getting the semantics of a distributed system right. In this talk, we'll explore how a clever mix of Clojure, and Apache Mesos can help simplify and decouple the inner workings of distributed systems.
As developers, we have been building rich web-based applications (or trying to) for some time and still can't avoid the complexity behind modeling the state of the world around us. In this talk we'll discuss a functional approach that radically simplify things using reactive web components backed by Elm, a functional reactive language that compiles to HTML, CSS and JavaScript. We choose Elm to bring us simplicity from FP principles and ultimately to bring its powerful type system to JavaScript on the browser.
These days many APIs are more than just simple REST services. Through WebHooks, APIs are talking back, giving us more information and prompting further action from our applications. But what is the best way to react to these demanding APIs?
We'll look at some services that use Webhooks, exploring reasons to use WebHooks and the emerging best practices. Then we'll look at the other side, implementing WebHook endpoints. Does consuming WebHooks make our application an API? What are the easiest ways to develop and test with WebHooks? We'll cover security, performance and standards all wrapped up with some live coded examples.
By the end we'll know how to handle anything an API can throw back at us.
Crystal is a new programming language with an intriguing mix of features. It has a Ruby-like syntax paired with a static type system. Built on LLVM, it allow users to directly call C code and compiles to efficient native code. This allows for performance that rivals C++ in a modern language that out-performs Go and Rust at tasks like parsing JSON. This makes it particularly well-suited for building web services and command-line interfaces.
TBA
There seems to be a new programming language every week, and for us busy developers we just don't have the time to keep up with them. But have you wondered what we might haved missed out on whilst we're busy working in our language of choice?
Having spent time with numerous programming languages the past few years I have learnt something new from each. In this talk, I'll take you on a whirlwind tour of the interesting concepts and ideas I have encountered, from F#'s type providers and Rust's borrowed pointers, to Elm's signals and Erlang's bit syntax to name a few.
Moving from Scala to Clojure, I was horrified and crippled by the lack of declared types. In desperation I cling to Prismatic Schema, which lets me describe parameters and return values, which are optionally enforced: contracts that look like types. In some ways this is even better than static types. Can I convolute these contracts into parameterized types? Let's explore these surprises.
TBA
Functional Reactive Programming was a thing that happened in the 90s. We’ve been rehashing these ideas, usually not even getting them right, for the past 20 years, and very little has happened to advance the state of the art. Very little, but that’s still something. We’re going to explore some of the advances we’ve made recently, with a particular focus on PureScript and the Halogen library, introducing concepts such as signal functions to improve the composability and type safety of UI components.
Typed Racket is a gradual type system for Racket, built entirely as a library. In this talk, I'll present why I wanted to build a gradual type system for Racket, and also how Racket made this possible. The story will cover macros, type checkers, compilers, and runtime systems, and demonstrate why we call Racket a "programmable programming language".
TBA
Web developers have typically been presented with a choice between performance or a productive development environment. With Phoenix, developers can have both while enjoying a wonderful set of abstractions for working with the new web, making streaming data to browsers, native mobile application or embedded clients a breeze. Finally, we will see how Phoenix leverages the Elixir language and the Erlang VM for writing maintainable and scalable code.
Designers and developers sometimes disagree about what would be best. By examining the differences and the similarities both can realise that they share much more than they think. Best practices in both realms are frequently identical and the goal is always the same: to communicate effectively, whether to a computer or a person. Join us on our mission to engage the design world, far more, in the world of open source and code.
Ember is an object oriented framework used to write ambitious web applications. It is also an example of extremely well decoupled framework. Taking advantage of that, in this talk I am going to show how to use it with a more functional approach. We will be using immutable data structures and transducers but also go “full monty” and write an Ember.Service using ClojureScript. All this while preserving the benefits of great tooling.
Much of the initial consternation when joining a team comes from a perceived expertise (or lack thereof) in the team’s chosen technologies. At Assembly, where disparate communities build projects together, we see this problem amplified by several orders of magnitude.
I want to talk about Assembly’s approach to micro-services not only as an architectural decision but also as a way to foster greater inclusion and collaboration by choosing the right tool (that is, language/framework) for each job. The task, I think, is one of translation that can be summed up in Wittgenstein’s famous aphorism, “The limits of my language mean the limits of my world” (Tractatus 5.6) — we need, in other words, to look at how our data is carried over from one place to another and to focus on the limits that our data crosses over.
I’ll show a couple of examples of cross-paradigm pollination and look at the ways that the Assembly community (in addition to the core Assembly platform) has benefited from running, say, Clojure and Go — or, more abstractly, Ruby and Wittgenstein — side by side.
The MISO stack allows developers to create distributed, resilient applications that work *for* the user. We've re-evaluated the old assumptions and taken a clean-slate approach so we can have all the benefits of hindsight but none of the baggage. The stack is comprised of MirageOS (unikernels), Irmin (distributed datastore), Signpost (identity & connectivity) and built using OCaml. I'll demonstrate how MISO enables us to build personal cloud infrastructure with some example applications of how users can regain control of their digital destiny.
Many modern rich web applications are so complex they deserve their own well-thought-out, dedicated approach to manage state, comparable in its power to the ones we have on a server. In this talk we’ll see why having something like a DB can help manage client-side state and will take a look at couple of new architectural possibilities this approach enables. Examples will be based on DataScript, a client-side Datalog engine written in ClojureScript.
TBA
Our product started in Ruby, but started to get envious of the data science ecosystem in Python. This talk is our answer to the question: How can you bring the power of the data science libraries in Python into Ruby? And can we do better than RPC? Our solution demonstrates using s-expressions to communicate between languages and the power that brings.
Immutability is an extremely powerful but not widely recognised concept in computer science. We'll talk about the applications of immutability in several seemingly unrelated areas like programming languages, data structures, version control, and deployment.

Haskell is an elegant and fascinating language that has made purely functional programming practical. In this tutorial, you will learn about the programming concepts that people like it for, such as pattern matching, type inference, partial evaluation, bounded polymorphic functions, and many more if time permits. I will structure this workshop around examples that I type into an editor and run in an interactive interpreter.
This is an all-new release of the tutorial Alexander Ulrich and I gave at bobkonf.de/2015.
Matthias has implemented his thesis at the Max Planck Institute for Computer Science in Haskell 15 years ago, and has been a user and proponent of functional programming ever since. He works as a software consultant for well-typed.com and is CEO at zerobuzz.net.
This workshop will cover the fundamentals of programming in miniKanren, an embedded domain specific language for constraint logic programming. We will begin with an overview of the miniKanren language, and will write a few simple miniKanren relations that "run backward." We will then write a more sophisticated miniKanren program: an environment-passing Scheme interpreter, written as a relation. We will extend the interpreter in various ways, and explore how the interpreter can be used for program synthesis.

In this workshop you will be provided with answers to the following questions: How to create hybrid mobile applications? What can hybrid mobile applications do? The Workshop will be using devmeetings convention and platform for better and more rapid development. "
Łukasz is a technology evangelist and software developer at Bank Zachodni WBK where he is creating a wide variety of state-of-the-art applications. Now he is strongly focused on mobile hybrid applications in the enterprise world.
I know that you already are a skilled software developer, designer or architect. You can craft beautiful and clean object oriented code. You can test and maintain it well and I manage complex abstractions of underlying domain models.
I want to show you something entirely different...
Remember Commodore 64? The highest selling computer model of all time?
Sadly it's not produced anymore for more than 20 years. But did you know that more than **50 new games** get released every year for this machine?
What if I told you that learning to program this ancient machine will make you a better developer?
Unique set of programming constraints, interesting hardware and a large community of enthusiasts make programming C64 a refreshing experience. It is not something that you will use directly in your day job. But learning 6510/6502 assembly will expand your perspective, especially if you've never had a chance to touch low level code.
It's also really fun :)
Michal is a señor software developer at Gunpowder Labs, where he works on creating great web and mobile apps for external clients. He strives to improve as a programmer and enjoys sharing the knowledge during Code Retreats and the Programming Workout project. He is also passionate about programming ancient computers and teaching others how to do it at 64bites.com.
Are you scared of JavaScript? Do you write (copy) your code (from the internet), but you don’t know why it’s (not) working? Would you like to learn how to build modern web applications? This workshop is for you!
We start with a crash JavaScript course focusing on those elements which are relevant to AngularJS. After that we implement an AngularJS application from scratch showing AngularJS basics: two-way binding, modules, and dependency injection. Eventually we demystify directives and show how to test the elements we have implemented before.
Tomasz is a Software Developer at Capgemini with 2 years of professional experience in developing AngularJS applications. In his everyday work he solves many development issues - luckily modern front-end frameworks and tools help him with this. He is happy with the growing importance of web applications and with the strong trend towards JavaScript frameworks.
