2019 Meetings

May 2019 Meeting

Hosted By

Skills Matter

Thanks!

The May 2019 meeting of LRUG will be on Monday the 20th of May, from 6:00pm to 8:00pm (meeting start at 6:30pm). The venue, Code Node between Moorgate and Liverpool St. stations, is provided by Skills Matter. Full venue and registration details are given below.

Agenda

Getting the next generation into coding

Pablo Brasero Moreno:

In the last few years, I've been involved in teaching coding to people from several walks of life, including children. In this talk, I'll share my thoughts and experiences on teaching children to code.

Monoids

John Cinnamond:

Mathematics can make you a better person. Well, not really. It can, however, help you think about programming. This talk provides a very quick introduction to a branch of mathematics called 'general algebra' and looks at how it can apply to programming. We then take a real world programming challenge and solve it algebraically, then convert that algebraic solution into working code. By the end you'll be left feeling confused, perhaps a little angry, almost certainly a little bored. But without even noticing anything has changed you'll soon start to look at difficult software problems and see past the superficial complexity to get a better understanding of the underlying structures at play. And you'll be a better person for it.

Writing more elegant queries with ActiveRecord

Josh Fleck:

So often, the biggest bottleneck to scaling is the database. It's also one of the areas where a little engineering effort goes a long way. This talk exists because I think it is very rewarding to write queries with ActiveRecord that are easily readable and able to scale. We'll walk through some real world examples of refactoring some mingin' ActiveRecord queries, learn optimisation techniques you can put to work right away, and build a deeper knowledge of relational databases.

Afterwards

All these talks will take us to around about 8pm, after which we have two choices for socialising with your fellow LRUG attendees:

  1. Code Node. Skills Matter run a bar with a choice of drinks (hard and soft) available. As well as other LRUG members you can network with attendees of the other meetups that Skills Matter are hosting on the same night.
  2. The Singer Tavern. This bar is a short walk north from Code Node (you can find it at 1 City Road, EC1Y 1AG). This pub has a decent food menu on offer as well as a selection of drinks and other LRUG attendees to help you while the evening away.

Regardless of what you choose to do, please remember that this part of the meeting is still covered by our code of conduct even though it does seem more informal.

If you can't attend the talks we'd still be very happy to see you at this part of the meeting. Do come along!

April 2019 Meeting

Hosted By

Skills Matter

Thanks!

The April 2019 meeting of LRUG will be on Monday the 8th of April, from 6:00pm to 8:00pm (meeting start at 6:30pm). The venue, Code Node between Moorgate and Liverpool St. stations, is provided by Skills Matter. Full venue and registration details are given below.

Agenda

Improve confidence in your code with mutation testing

Rafał Szałański:

In this talk I'm going to explain mutation testing and how it helped me be more confident about my Ruby code, and also how to write better Ruby in the future.

Giving my enemies a voice

Shen Sat:

I'm remaking a classic boxing video game, with a twist: the narrative is defined through the hopes, dreams and desires of the player's opponents, not the player themselves. I'll be talking about flipping enemy design in games on its head, as well as demoing a key part of my boxing game: the trash-talk engine!

Afterwards

We plan to finish around 8pm. That's not the end of the evening though, so if you'd like to socialise with other LRUG attendees and chat about all the talks you've just seen you have two choices:

  1. Code Node. Skills Matter run a bar with a choice of drinks (hard and soft) available. As well as other LRUG members you can network with attendees of the other meetups that Skills Matter are hosting on the same night.

March 2019 Meeting

Hosted By

Skills Matter

Thanks!

The March 2019 meeting of LRUG will be on Monday the 11th of March, at the slightly later time 6:30pm to 8:30pm (meeting start at 7pm). The venue, Code Node between Moorgate and Liverpool St. stations, is provided by Skills Matter. Full venue and registration details are given below.

Agenda

RSpec - Level Up

Jon Rowe:

You've been using RSpec for a while, you know how to write tests, but you’re not sure you're getting the most from it. This is a quick run through of some of the lesser known, more advanced features of RSpec.

Education, Recruitment and Technology: What needs to change?

Melissa Tranfield:

The traditional education system is letting down the next generation by not preparing them for the future of work. Edify is working to change this whilst planning to disrupt the public sector through the innovation of digital policy.

Representations count

Tom Stuart:

In your grandparents’ attic you discover a mysterious old computer. You boot it up and discover it runs Ruby, but doesn’t support negative numbers! How can you implement negative numbers in an elegant way? We’ll explore two solutions and discover how important it is to pick the right representation.

Afterwards

We plan to finish around 8:30pm. That's not the end of the evening though, so if you'd like to socialise with other LRUG attendees and chat about all the talks you've just seen you have two choices:

February 2019 Meeting

Hosted By

Skills Matter

Thanks!

The February 2019 meeting of LRUG will be on Monday the 11th of February, from 6:00pm to 8:00pm (meeting start at 6:30pm). The venue, Code Node between Moorgate and Liverpool St. stations, is provided by Skills Matter. Full venue and registration details are given below.

Agenda

Lightning Talks!

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

A different take on validation using the dry-validation gem

Alfredo Motta:

A short introduction to the dry-validation gem and whether or not it might be a good fit for your next project. Both the internals of the gem based on a set of predicate logic primitives, and the API surface which uses a schema based declarative approach are different enough from existing alternatives that you should really have it under your radar.

Capybara architecture overview

Ben Holmes:

We'll briefly review the implementation of Capybara's DSL for browser testing.

Automating Infrastructure Tasks with the Serverless Framework

Bernat Rafales:

How to leverage serverless tools to help you manage parts of your infrastructure

Using Rails with a Content Distribution Network (CDN)

Gideon Goldberg:

What is a CDN? Why use one? What support does Rails provide out-of-the-box and what customisations can you make to do more?

A developer and a designer, getting along famously

Celia Collins and Boris Divjak:

A short story about how a developer and a designer can learn to fuel each-other’s ideas and why this matters. When our differences enable us to see things from different perspectives, we can take on bigger and more complex problems. When we collaborate every day, nothing can stop us.

Humans are hard

Matthew Rudy Jacobs:

Lessons learned from the past decade of coding, learning to understand and work with people.

How to craft your commit history

Tatiana Stantonian:

A talk about the importance of narrating your code changes, with practical tips on using git to edit and reorganise your commits. In this talk you'll learn to resolve merge conflicts peacefully, use git rebase interactive --autosquash, refer to your commits using :/keyword instead of their SHA, and other exciting things!

Using ActiveRecord types for backwards compatibility

Alex Balhatchet

How the CharlieHR team handled a tricky change by using a custom ActiveRecord type as a temporary backwards compatibility layer between the code and the database.

Afterwards

Even with all these talks we still plan to finish around 8pm. That's not the end of the evening though, so if you'd like to socialise with other LRUG attendees and chat about all the talks you've just seen you have two choices:

  1. Code Node. Skills Matter run a bar with a choice of drinks (hard and soft) available. As well as other LRUG members you can network with attendees of the other meetups that Skills Matter are hosting on the same night.

January 2019 Meeting

Hosted By

Skills Matter

Thanks!

The January 2019 meeting of LRUG will be on Monday the 14th of January, from 6:00pm to 8:00pm (meeting start at 6:30pm). The venue, Code Node between Moorgate and Liverpool St. stations, is provided by Skills Matter. Full venue and registration details are given below.

Agenda

Ruby Golf!

As is tradition, our first meeting of 2019 will be a slightly different kind of thing. Instead of talks, we'll be pulling all our not-suitable-for-production Ruby tricks out of the bag and playing a few rounds of Ruby Golf!

For those unfamiliar with this, put your clubs away: code golfing is where you try to solve a programming problem using the fewest possible number of characters. Unlike the rest of the time, we don't care about elegance, we don't care about readability, and we definitely don't care about performance – make it short, then make it shorter!

Some quick tips to get you going:

  • Descriptive local variable names? No thanks: a, b, and c will do just fine.
  • Why use collect when you can use map?
  • You may wish to { brace } yourself, lest you do worse in the end

Format

  • Bring your laptop and a recent Ruby version! Anything 2.2 and up should be fine
  • We think this'll be more fun if you work in teams, so you can pool your ideas – chances are that you know a trick or two that others haven't seen, and vice versa
  • We will provide a repository of code which you can clone on the day. This will contain tests to give you confidence that your solution works, along with some helpers to count characters fairly across everyone participating

There are no official prizes, just bragging rights in the pub afterwards. Speaking of…

Afterwards

We aim to finish by 8pm (although it may over-run depending on how much fun we're having!).

If you'd like to socialise with other LRUG attendees afterwards you have two choices:

  1. Code Node. Skills Matter run a cash bar with a choice of drinks (hard and soft) available. As well as other LRUG members you can network with attendees of the other meetups that Skills Matter are hosting on the same night.
  2. The Singer Tavern. This bar is a short walk north from Code Node (you can find it at 1 City Road, EC1Y 1AG). This pub has a decent food menu on offer as well as a selection of drinks and other LRUG attendees to help you while the evening away.

Regardless of what you choose to do, please remember that this part of the meeting is still covered by our code of conduct even though it does seem more informal.
