Vaidehi Joshi

The Cost of Data

The internet grows every day. Every second, one of us is making calls to an API, uploading images, and streaming the latest content. But what is the cost of this—is it free? This talk explores the reality of data, and what responsibilities we have as creators and consumers of tech.

She also co-hosts the Base.cs Podcast, and is a producer of the BaseCS and Byte Sized video series.

Xavier Shay

My Experience With Experience

Becoming a senior contributor to your organization takes years. It's a process that is stubbornly hard to accelerate - it takes much more than drilling code katas! In this talk Xavier reflect on situations he's encountered over the last decade, and apply some academic models he's found useful to explain and learn from them. By doing so we can better understand the limits to learning and prepare ourselves to make the most out of our experience.

About Xavier

Xavier recently moved back home to Melbourne after spending eight years in San Francisco, mostly as an engineering leader at Square. Currently working at Ferocia building Up, a fancy new digital bank. He's scheming to introduce the RubyConf 5K tradition to Australia.

Lena Plaksina

Just my type: things I learned from writing my own programming language

Do the principles on which a programming language is based shape the community that grows up around it? Heck yes. While writing my own programming language, I was reminded that language creates (not merely carries) meaning. I also learned that you don’t have to be Grace Hopper to write your own.

About Lena

Hi, I’m Lena. I’m an avid cat rescuer, learning enthusiast, and Rails Bridge Wellington organising committee member. I started out in design, but fell for web and software development during my first industry internship. I've been writing Ruby since 2015, and I'm currently learning other languages to expand my toolkit. I’m all about finding patterns, building and communicating software in a way that helps everyone understands it, and failing better – mistakes make me a better developer, and I believe that failing is just an opportunity to learn. When I’m not coding, I’m watching movies with my 3-legged rescue cat Warlock, collecting enamel pins, and helping out and/or presenting at tech community events around town.

Selena Small and Michael Milewski

10X your teamwork through pair programming

A roller coaster journey of how to get the most out of pair-programming. Live on stage acting out highs, lows, do’s and don’ts of pair-programming. Laughs and tears are guaranteed as the audience connect on the difficulties and ultimately the rewards that can be reaped through effective pairing.

About Selena and Michael

Selena and Michael met through work at Fresho! but soon realised they are the kind of friends who would rather talk tech at a party. So they turned their party times into numerous hackathons, coding camps, and duo talks and workshops on topics around test driving software and pair programming.

Adel Smee

Inclusiveness - It's In Your Hands

The tech industry is a way from creating a safe, nurturing, inclusive culture. This talk will encourage you to get involved in diversity and inclusion work at your company in whatever way makes sense to you. It includes a few pointers to get you started and stories to motivate you along the way.

About Adel

Adel Smee is an Engineering Manager at Zendesk where, for the last four years, she has led innovation projects across a variety of technologies and grown a number of high performing teams. Her career in tech started with teaching people to code, before she decided to break out and get paid to do it commercially at a startup, then at Lonely Planet, and then at Zendesk. Along the way she realised that her main implicit motivator is delight in the success of others, which turns out to be a really useful quality in a manager. She is obsessed with what makes people (and herself) tick and loves to hear how she is getting it wrong so she can do better. Adel is an incurable optimist who believes that one day we’ll live in a world where everybody likes their job as much as she does, but isn’t naive enough to think that day is coming any time soon.

Matthew Borden

Murdering our Mongo Database (or how we migrated to a relational database)

This is the story of migrating large parts of an application’s data layer from MongoDB to MySQL with zero downtime using Ruby. We’ll cover designing schemas to represent untyped data, dual writing to both databases, migrating old data and staging the cutover to the new database.

About Matthew

Matthew is a Site Reliability Engineer at Seer Medical maintaining a cloud based epilepsy diagnostics system. Previously, he was at Stile Education developing a science education platform for high school students. He enjoys the detective work of debugging issues in production, the delightful nature of writing Ruby and finding new ways to break systems early before they break in production.

Dana Sherson

300x faster ruby

Everything I’ve learned about how to make ruby go fast with examples from writing a spell-checking gem I’ll go into how to improve your intuition about slow code, how to use and read the output of ruby-prof, rb-spy, Benchmark, Parallel, fast-ruby, etc, and the pitfalls to avoid when optimising code

About Dana

I’ve been writing ruby for about 11 years now and have thoroughly fallen in love with the language. My other hobbies include writing bad fiction and taking bad photographs. I’m a kiwi and a vegetarian so you know I’m a terrible person.

Jameson Hampton

Walking A Mile In Your Users' Shoes

Developing apps for users in different demographics is inherently differently than developing apps just for ourselves and for other programmers. Understanding the needs of our users — and learning to foster empathy for them — is just as much of a skill as learning Rails, Java or PHP!

About Jameson

Jamey is a non-binary adventurer from Buffalo, NY who wishes they were immortal so they’d have time to visit every coffee shop in the world. They're a Rails engineer who has recently been taking the plunge into DevRel and a panelist on the Greater than Code podcast. In their spare time, they do advocacy in the transgender community, write comics and spend as much time as possible in the forest.

Paul Joe George and Do Xuan Thanh

Build a voice based smart home using Sinatra & mruby/c

Are you tired of searching for the remote controls? We were in that category and that’s why we decided to replace remote controls and start using a smart assistant like Alexa instead. This talk will share knowledge on how to achieve this by using mruby/c and Sinatra.

About Paul and Thanh

Paul and Thanh are software developers at Monstar Lab Inc. Living in Matz's hometown, where Ruby is more than a programming language. They use Ruby purely for fun as Ruby is fun. Using Ruby only for traditional Ruby on Rails projects never satisfied them. For that reason they decided to experiment using mruby/c - a mini version of Ruby for one-chip microcontroller programming. Currently they are building more and more practical applications to inspire other Ruby lovers to start using Ruby for IoT.

Ernesto Tagwerker

Escaping The Tar Pit

Nobody wants to inherit a project that reeks but here we are: Stuck in the tar pit. How can we get out? Could we have avoided it in the first place? In this talk you will learn how to use a few, great Ruby gems that will guide you out of that sticky tar you are in.

About Ernesto

Ernesto is the Founder of Ombu Labs, a small software development company dedicated to building lean code. When he is not playing table tennis, he likes to maintain a few Ruby gems including database_cleaner and email-spec. He is passionate about writing less code, contributing to open source, and eating empanadas.

Brandon Weaver

Tales from the Ruby Grimoire

The Grimoire is a collection of Ruby tricks. It’s a performance, a storybook adventure told by a particularly mad narrator weaving tales from the darkest corners of Ruby. Give your audience an experience they won’t forget, and a group of mischievous little lemurs a chance to warm your hearts.

About Brandon

Brandon is a Ruby Architect at Square working on the Frameworks team, defining standards for Ruby across the company. He's an artist who turned programmer who had a crazy idea to teach programming with cartoon lemurs and whimsy.

Carmen Chung

How To Write Tech Documentation That Will Save Your Career

“Save your career?!” You’re probably thinking. “That’s a bit dramatic!” But so is someone saying “Thank goodness for these docs!” - and trust me, it does happen. In this talk, I’ll share battle-tested tips for writing tech documentation that people will come back to, time and time again.

About Carmen

Carmen is a software engineer, writer, and conference speaker, with a reputation for breaking people's code. Prior to her move into tech, she worked internationally as a corporate lawyer for almost seven years.

Julian Doherty

Escape Your Framework

Rails and other frameworks let you quickly throw together ideas to get up and running quickly. But as your app grows, this can limit what you can do. How can we set ourselves up to get the benefits that come from using a framework, while staying flexible and not beholden to it?

About Julian

Julian is a lead developer with 20 years experience, and has been hacking on Ruby for the last 13. Originally from Wellington, New Zealand, he now calls Melbourne home. Currently working at Envato, he has spent time at some of the biggest Rails shops in Australia. Julian also runs the Elixir Melbourne meetup group, and tries to spend as much time as possible inflicting functional programming paradigms on codebases he works in.

Rob Howard

A Message to the Stars

In 1977, NASA launched the Voyager probes into space. Each carried a copper ‘vinyl’ record, with music, speech… and 115 images, all inscribed on the disc as audio! In this talk we’ll pretend to be aliens; we’ll use Ruby to read the audio, recreate the images, and learn some space history too. 🚀✨

About Rob

Rob Howard is a web developer and figurative magpie. Having spent his career so far learning and mixing the nice parts from different programming languages, he'd like nothing better than to help technical communities learn more from each other, build better stuff, and have fun in the process.
