Meetings

March 2024 Meeting

The March 2024 meeting of LRUG will be on Monday the 11th of March, from 6:00pm to 8:00pm (meeting starts at 6:30pm).

This month we're hosted by the lovely folk at Canva in their offices, on Hoxton Square. Full venue and registration details are given below.

Agenda

Understanding RuboCop's workflow

Alexey Schepin says:

Many Ruby engineers are familiar with RuboCop and eager to write custom cops. However, existing resources often prioritise Abstract Syntax Tree (AST) concepts over RuboCop's workflow and built-in tools. This talk aims to rectify this by focusing on understanding RuboCop's workflow and its practical implications for writing custom cops. Join us to explore the fundamentals of RuboCop's workflow, empowering you to develop custom cops with ease and clarity.

How to Stop Being a Subject Matter Expert

Luke Thomas says:

Tactics for helping that stressed-out single point of failure in your life become a happier member of a team…of multiple points of failure.

WTF is Technical Strategy

Laurie Young says:

The phrase "Technical Strategy" is often used by senior leaders when they want something from their tech teams. However, it's an unclear phrase that doesn't explain what is needed or why. In this talk, you will learn what's behind the phrase, but also how anyone from a CTO to a new developer can use that knowledge to drive conversations that will help not just the leadership but the whole organisation.

Afterwards

When the talks come to an end we'll decamp to a local pub for some food, some drinks and some chat with your fellow attendees.

Of course, even though this is the socialising part and seems more informal, please remember that still we consider it to be a part of the meeting and covered by our code of conduct.

Agenda

Lightning Talks!

Our February meeting is our annual event devoted to short talks of no more than 10 minutes.

Data pagination for jekyll-paginate-v2

Jay Caines-Gooby:

A quick dive into getting data-pagination (.csv, .json, .tsv & .yaml files in your _data directory) working with the jekyll-paginate-v2 gem. After deciding that I wanted to archive my posts to a Slack #music-we-like channel, I wanted to also make the archived posts paginatible…

Using devcontainers with Ruby

Jonathan James:

When an engineer joins your organisation, how long does it take for them to configure their development environment? I will discuss using devcontainers with VSCode to reduce this time from "days" to "minutes''.

Contract testing between Ruby applications

Katya Essina & Sarah O'Grady:

  • what is contract testing & how it works
  • why we need contract testing at Funding Circle
  • what a contract test looks like for a Ruby application
  • how contract testing works in practice

What is ruby really capable of?

fell sunderland:

I'd like to do a whistlestop tour of a few different gems I've written over the years, with the aim of talking about having fun whilst learning what ruby is capable of. I'd like to showcase things like aspectual for bringing aspect oriented programming to ruby, cherry-pick for when you miss import foo from bar, overload for when you want to really have optional arguments do something different, and more!

Co-locate your template & javascript code with Phlex & AlpineJS for a happy developer!

Martin Tomov:

More than 100 lines files are bad? Not if you have the right tools! Inline your templates, JavaScript, business & controller logic for maximum productivity!

Be More GARY: How to up your RSpec Game

Scott Matthewman:

Elevate your RSpec tests by questioning common DRY practices. Enter the GARY method, where strategic repetition enhances test clarity and maintainability. Resist premature refactoring and convoluted logic, leaving yourself with clearer tests that document your code. Go ahead, repeat yourself.

Making games with ruby

Paolo Fabbri:

Learn how the Dragonruby game engine makes game development faster and simpler for everyone, from beginners to pros. Explore its key features, and jumpstart your journey into the world of game creation. Join us to transform your ideas into reality with ease!

Afterwards

When the talks come to an end we'll decamp to a local pub for some food, some drinks and some chat with your fellow attendees.

Agenda

Sky Computing

Kevin Sedgley says:

What comes after cloud computing? Cloud computing is convenient, ubiquitous and relatively cheap. But it also locks developers into proprietary solutions that make migrating to another provider or bringing your solutions back in-house difficult and expensive. If AWS, Google Cloud Computing, Azure and all the others are clouds, then we also need a sky. Researchers at Berkeley and other institutions have proposed sky computing: an interoperability layer that removes technological lock-in and enables multi cloud application development.

Leveraging Localised Gems (LLGems): Re-using Code the Ruby Way, Safely

Joel Biffin says:

The talk takes a look under the hood of our Rails monolith, our Rails Engines, and how we share code between them. It's a bit like a kitchen experiment – blending the best of both worlds to enhance the Separation of Concerns, while still keeping our favorite code recipes within reach. I'll share our adventure of moving some Kafka infrastructure code from the main Rails app into a local gem (with zero downtime!). Think of it as giving the code a new home where it can be shared across our Rails Engines. We've also managed to preserve our unique, in-house testing infrastructure in the process which is a serious Brucie bonus!

Agenda

Test Smarter, Not Harder - Crafting a Test Selection Framework from Scratch

Christian Bruckmayer says:

The simplest way of running tests is to run all of them, regardless of what changes you are testing. However, depending on the size of your test suite, this will either get slow or expensive. At Shopify we have almost 300,000 Rails tests and we add 50,000 more annually. The sheer amount of tests and their growth makes it impossible to run all tests, all the time! Hence we implemented a framework to only run tests relevant to your code changes.

We will build a test selection framework from scratch in this workshop. We will begin by exploring the fundamentals of such a framework: code analysis. After that we will dive into minitest reporters, how they work and how we can use them to generate a test map. Finally we will use the generated test map to only run tests relevant to your code changes. Attendees will walk away with a solid understanding of what test selection is, how it works and how to implement it.

This is a workshop, so bring your laptop!

Afterwards

When the talks come to an end we'll decamp to a local pub for some food, some drinks and some chat with your fellow attendees.

Outside Technology: Building bridges between engineers and everyone else

Naomi Christie says:

Naomi will take you on a journey from her previous career outside technology to her current career as a software engineer highlighting some of the (many) things she had to learn along the way, providing insight into why misunderstandings are common between engineers and their stakeholders and offering some ideas on how we can bridge that gap.

The Art of Talk Design

Melinda Seckington says:

Everywhere you look, stories surround us, and everyone has something that’s worth sharing with others. As speakers, we need to understand how to structure our talks so they can have the best effect on the audiences we are trying to reach. How do you discover the right angle and the right story for a talk? How do you frame your story?

Within tech we know how to approach building a new product: we research our user base, we figure out what and for who we’re trying to create something for and we make sure we constantly iterate on what we’ve come up with. So why aren’t we taking the same approach for our talks?

This talk will examine how to get in the right mindset of examining your talk ideas, and will introduce a framework of how to design and iterate on your talk. It will focus on several exercises and questions to help you create the best talk for the story you’re trying to tell.

BorrowMyDoggy - Connecting dogs and people via Ruby

Rikke Rosenlund says

BorrowMyDoggy connects dog owners with local borrowers for walks, weekends and holidays. Via BorrowMyDoggy, borrowers get happy dog time, owners get help with taking care of their dogs, and dogs get more love and attention (it's a win-win scenario). We started by winning the Lean Startup Machine, then received a crazy amount of media attention and by now have built a community of +1 million members in the UK and Ireland, and are working with some of the biggest players in the pet space. Come and listen to how a simple idea has now turned into a well known brand.

Your talk here!

Get in touch with us at talks@lrug.org if you'd like to speak. We're always happy to help new (or not so new) speakers.

Afterwards

Once we're done with the talks we'll leave the venue (after doing our best to help tidy up) and find a local pub to visit so we can eat, drink, and discuss the talks we've just heard.

The Functional Alternative

Ju Liu says

We'll start with a simple Ruby Kata and solve it together, live, with imperative programming. We'll then fix the many, many, many things we got wrong. Then we'll solve the problem again using patterns from functional programming. You'll leave this talk with a clear and concrete example of why functional programming matters, why immutable code matters, and why it can help you writing bug-free code. The next time you find yourself writing imperative code, you might consider… the functional alternative.

Back in my day…

Paul Battley says

I've been working with Ruby since the early 2000s. Ruby has changed a lot in that time, but we don't always remember how much. Let's rewrite a short program so that it runs in a twenty-year-old version of Ruby and see how much syntax and performance has changed for the better in twenty years
