The December 2018 meeting of LRUG will be on Monday the 10th of December, from 6:00pm to 8:00pm (talks 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.


The Case of the Missing Method — A Ruby Mystery Story

Nadia Odunayo:

Business is slow for Ruby Private Investigator, Deirdre Bug. She’s on the verge of switching industry when she gets a call from an anxious young man. "Some class methods have gone missing," he tells her breathlessly. "I need your help."

Deirdre takes the case and begins exploring Ruby objects behind the scenes. Though she thinks she's on familiar ground — Ruby's object model, method lookup — she's about to discover that she really has no clue.

The problem with compiling Ruby

Vidar Hokstad:

To get maximum performance out of a language, compilation is key, and people > have been trying to compile Ruby for a long time, ranging from jRuby and Truffle Ruby to the experimental method JIT in Ruby 2.6. But Ruby is a very challenging language to compile efficiently. The talk will explore some of the reasons based on what I've learned while working on my own Ruby compiler as described in my series of blog posts at

Pro Capybara Herding: Feature Testing Tips

Oli Peate:

How do I debug JavaScript during a test? And how about emulating mobile devices? More importantly how do I mute this video I need to test?! Learn about these topics and more in this lightning talk about testing with Capybara & Chrome


We aim to finish up the talks by 8pm. This doesn't mean you have to go home though, if you're keen to talk about what you've just heard, or just mingle with your fellow attendees you have a couple of 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 hosing 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.

Don't worry that you'll miss out on this part if you can't make the talks. Attendance of the talks is far from mandatory to attend the socialising afterwards, so please do come along anyway if you can.

Venue & Registration

Prior to attending you should familiarise yourself with our README paying close attention to the code of conduct which applies to all attendees at the talks and afterwards in the pub.

To secure a place at the meeting you must register with our hosts Skills Matter. It helps to make sure we have the room laid out with enough chairs, and in extreme cases that we get priority on the larger rooms over other groups using the space on the same night. Also, it's good manners, so please do register with Skills Matter.
