Rails Girl at Rails Girls Summer of Code
I'm a participant in this year's Rails Girls Summer of Code, which is a worldwide, three-month program aiming at supporting women on their way into programming. With only about three months of experience with coding, I'm still very new to this whole wondrous world of code, but extremely excited about it. I have a background in linguistics and humanities, but got very bored with these and my previous jobs in Custumer Service and Recruiting. Therefore, I'm now on my way to becoming a software developer.
Rails Girls Summer of Code participant at SoundCloud
Brigitte Markmann participated as a volunteer in this years edition of Rails Girls Summer of Code. She has a background in media management and administration and wants to change careers to become a developer.
Besides that she identifies as a Berliner (although there is no ocean and the climate is too cold), thinks that monkeys are the funniest animals and loves good food.
Software Engineer at Factual
Zach sells the Balloon of Fatigue and the Balloon of Ora Pro Nobis and the Rune Balloon and the Balloon of the Last Thing to Do at Night; these are saffron-, cinnamon-, salt-, and celery-colored, respectively.

Ryan Levick
When I started working at 6Wunderkinder a few years ago, I had no experience in software. I had taught myself the basics of web development (HTML, CSS, basic Javascript) but had not yet discovered the real joy of programming.
While at 6Wunderkinder working on the Marketing and then QA teams, I taught myself how to program first in Ruby and then in many other (particularly functional) languages.
Learning never stops, but now I enjoy spreading some of the knowledge I've gained with others.
Garret Smith
Nearly all complex life reproduces by sex, despite the high cost when compared to the alternative of cloning. Sex randomly reassembles working solutions, starting over. If you want to build the perfect football team, you clone Robert Lewandowski - you don't use his kids!
If sex is so costly to optimized solutions, why is it nearly universal in nature? The answer lies in the importance of diversity -- having different options to chose from is so valuable in nature, complex life pays the high price of sex.
Can this lesson be applied to software development? Does it pay to know and use multiple languages? Is there inherent value in building heterogeneous systems using a wide variety of technologies?
In this talk, Garrett Smith will explore various phenomena from biology and consider their application to the process of building software. He'll look at death, speciation, photosynthesis and other fascinating topics that can teach us valuable lessons for our daily work as programmers.
Henri Bergius
NoFlo is a flow-based programming environment for JavaScript. Originally built for Node.js systems automation, it can also be used for developing full-stack applications from the browser to microcontrollers like Arduino.
With NoFlo developers build their applications by wiring data streams together between different pre-built or custom components. The NoFlo environment is fully browser-based and can connect to NoFlo instances running on remote servers, allowing inspection and rewiring of running software.
The NoFlo development environment is open source and was successfully crowdfunded on Kickstarter in fall 2013. Now it is time to show the world how it works.
You can learn more about NoFlo at http://noflojs.org
Justyna Walkowska
- Should everyone learn programming these days?
- How do you teach programming to arts and humanities graduates?
- Can we learn something from them?
- Will they steal your job?
- Can you become a programmer at a later stage in life?
- How much mathematics does a coder really need?
- Which paradigm is best for absolute beginners?
- Can a 'proper' IT education be a hindrance?
Having worked on very 'intercultural' and multi-domain projects, I would like to share my opinions and conclusions on the above (and related) matters.
Michał Łusiak
When you think about .NET developers, you probably imagine boring guy in a suit coding somewhere in cubicle in glass tower of some evil enterprise company. Surrounded by others alike. Thousands of them. And we earned it. But this world is changing at very fast pace. Microsoft is open sourcing tons of stuff, and bringing to our availability new shiny tools and awesome languages. Like F#. And there's big community, doing lots of stuff to make those technologies available on all platforms, with full support of Redmond.
In this talk I'm gonna show you how mature this solutions are. How easily you can develop applications that will run on Windows, Mac or Linux. Or how with very high code reuse you can write apps for all major mobile platforms. All with magic of functional programming provided by F#. It's gonna be awesome
Adam Schmideg
How do you keep with your work when you're looking for a performance bottleneck for weeks? How do you find a bug in a legacy system you don't even understand? What do you do when you're bored to death of writing the same code day in, day out? How do you handle your frustration that you didn't keep a deadline? How do you handle the frustration of your boss and your team members? How do you find the time to finish your hobby project?
Programming issues have psychological aspects, but few engineers talk about them. I'm going to shed some light on the grey zone between programming and psychotherapy.
Ute Mayer / Magdalena Frankiewicz
Ute and Magdalena teamed as the CodePadawans for three months full of code by the Rails Girls Summer of Code initiative. They will talk about the program, their personal experiences and present the latest results of working on Ataru, a documentation testing tool.
Kathi Zwick / Brigitte Markmann
My team pair (Brigitte Markmann) and I will share what it feels like to burst in on the profession of a software developer - as a woman and as someone with no prior experience with coding.
Michael Snoyman
Haskell is well known for its strong, static type system. Javascript, by contrast, is a dynamic, weakly typed language. While they share some functional features, the two languages are quite different. But when we write a web app with a Haskell backend, these worlds inevitably collide. How do we bridge these two worlds?
In this talk, we'll cover some of the common techniques, including Haskell->JS compilers and well defined cross-language APIs. We'll also describe ways in which we can keep the benefits of strong typing, even when interacting with code that ignores types entirely.
Adam Dudczak / Tomasz Jackowiak
Why we are submitting this talk? Because Go is cool and we would like to hear more about this language ;-). In this talk we would like to tell you about our experience with development of microservices with Go. Go enables devs to create readable, fast and concise code, this - beyond any doubt is important. Apart from this we would like to leverage our test driven habbits to create bulletproof software. We will also explore other aspects important for adoption of a new language.
David Nolen
We live in a time of vast computational resources - many of us carry around in our pockets what just thirty years ago would have been considered a supercomputer. But it's not just the hardware, these bite sized supercomputers run software using state of the art dynamic compilation techniques to deliver stellar performance without sacrificing flexibility.
While all of this may sound incredibly futuristic, many of us still program these Dream Machines with miserly techniques not far removed from the best practices of the 1960s.
We have cycles to spare, by investing some of them in immutable data structures our programs get new wonderful properties that enable us to design solutions at a much higher level of abstraction. Om is a new library I've created just to explore these possibities. While Om itself is written in ClojureScript, we'll focus primarily on the big ideas present in Om all of which are easily portable to other languages.
Honza Král
"Last year Elasticsearch released a set of official clients in multiple languages (Js, Perl, PHP, Python, Ruby, ...). The goal of those libraries was to provide a consistent API to Elasticsearch even for people switching between languages. In this talk I would like to walk you through the process from reasoning, conception and implementation.
I will show how we designed the clients so they both feel native to their environment and provide a consistent look and feel, what were the challenges and how we chose to approach them."
Agata Maroń
Have you ever thought about building a real agile company? Is it possible to create a software house with clients all over the world, and still be agile? How do you implement agile principles like self-organizing teams, open communication, and willingness to change, and still be able to work efficiently?
If you need a few tried and true methods for managing a company using agile methods, this talk is for you. I will show how STX effectively built agile software development teams to achieve great results. You will understand how to organize internally to make your clients confident.
Finally, I want to inspire you not only to think about the big picture, but the small, concrete steps you can start to take in your company now.
Lucas Dohmen
Domain Driven Design is a software development process that focuses on the finding a common language for the involved parties. This language and the resulting models are taken from the domain rather than the technical details of the implementation. The goal is to improve the communication between customers, developers and all other involved groups. Even if Eric Evan's book about this topic was written almost ten years ago, this topic remains important because a lot of projects fail for communication reasons.
Relational databases have their own language and influence the design of software into a direction further away from the Domain: Entities have to be created for the sole purpose of adhering to best practices of relational database. Two kinds of NoSQL databases are changing that: Document stores and graph databases. In a document store you can model a contains relation in a more natural way and thereby express if this entity can exist outside of its surrounding entity. A graph database allows you to model relationships between entities in a straight forward way that can be expressed in the language of the domain.
I want to look at the way a multi model database that combines a document store and a graph database can help you model your problems in a way that is understandable for all parties involved.
Zach Tellman
We routinely make systems that exceed our ability to understand completely. Instead, we explore pieces at a time – small local details or large global abstractions, but rarely both at once.
But software is far from unique in this; we’re surrounded by physical and social systems that are too big for any one person to understand. This talk is an exploration of how other, older disciplines have approached these problems, and what we as software engineers can learn from them.
Jack Franklin
The world of dependency management in JavaScript is full of different options and methods. In this talk we will examine some of the popular solutions including RequireJS, Browserify, Component and more. We'll also look at the ES6 Modules implementation and how we can use ES6 today with Traceur.
Darko Fabijan
Rails has established a norm in how easy and pleasant writing web applications can be. It helped enormously with establishing Ruby community and it's influence spread far beyond Ruby. The Elixir programming language is a descendant of Ruby and the great ecosystem around it. It was created by José Valim, Rails core team member. Phoenix is a web framework written in Elixir which tries to incorporate many great practices from Rails but also go beyond by leveraging the distributed and parallel computing features of Elixir. I would like to introduce Phoenix to the community by creating a chat application which will show how easy it is to create real-time web applications with next generation of web frameworks and programming languages.
Alexander Solovyov
Most in-browser WYSIWYG editors are working by modifying their data in-place, and at some point I decided I wanted more control and visibility on what's going on. That talk is going to be a post-mortem for what happened.
Michał Ślaski
In this talk we will discuss thinking in a concurrent programming language along with the problems it has to solve. We will take a look at the real tools Erlang gives you to write highly-available systems that let you sleep through the night: dynamic tracing and remote REPL. We'll see how these tools are used.
Michal Taszycki
Some people say that **Ruby is dying**.
Well.. I'd say **it's more alive than ever**.
Few years ago Ruby developers could only envy Javascript programmers while their favorite language was becoming ubiquitous.
Now, thanks to RubyMotion we can write desktop and mobile (iOS and Android) apps. Opal allows us to execute Ruby in a browser. On top of that we have mruby that can be embedded in ANY C or C++ application.
Even your arduino can run Ruby now!
**With these tools we can finally write cross-platform Ruby applications.**
After this talk you'll know how and you'll be eager to try it yourself.
Anna Wszeborowska
I am going to say a few words about global PyLadies society as well as discuss what we do and try to accomplish here in Poland.
Anna Warzecha
The talk will cover the idea of Django Girls, how it all started, what are future plans for Poland and for international chapters.
Joseph M. Bach
For the past 50 years the art and craft of programming hasn't changed much. If anything, we have forgotten our history, repeatedly reinventing it poorly. The primitive tools we use today hinder us from building the robust software systems of tomorrow, and the new and shiny programming languages which we adopt every few years seem to systematically ignore decades of research in computer science. As programmers, we spend most of our work days fighting complexity by throwing more complexity at it.
Gregory Letribot
How do you monitor performance for one of your clients on a specific user segmentation when dealing with billions of events a day ? With over 2 billion ads served and 230Tb of data processed a day, we at Criteo have a comprehensive need for an interactive analytics stack. And by interactive, we mean a querying system with dynamic filtering to drill down over multiple dimensions, answering within sub-second latency.
This session will take you on our journey with Druid, ""an open-source data store designed for real-time exploratory analytics on large data sets"". We will walk attendees through Druid's architecture and noticeable concepts, how relevant they are for some use cases and how it really performs.
John Hughes
Even the best test suites can't entirely prevent nasty surprises: race conditions, unexpected interactions, faults in distributed protocols and so on, still slip past them into production. Yet writing even more tests of the same kind quickly runs into diminishing returns. I'll talk about new automated techniques that can dramatically improve your testing, letting you focus on what your code should do, rather than which cases should be tested--with plenty of war stories from the likes of Ericsson, Klarna and Volvo Cars, to show how these new techniques really enable us to nail the hard stuff.
PolyConf will take place at University of Medical Science Conference Center in Poznan, Poland. The center has an auditiorium that can host 450 and additional workshop rooms.
