October 2025 Meeting

The October 2025 meeting of LRUG will be on Monday the 13th of October from 6:00pm to 8:00pm (meeting starts at 6:30pm).

This month we’ll be hosted by Bloom & Wild in their offices between Vauxhall and Oval tube stations. Not only will they be providing the space, they’ll also be giving us some pizza and drinks! Full venue and registration details are given below.

Agenda

Extreme Versioning

Harry Lascelles says:

An exploration into the world of Software Versioning, with an emphasis on the RubyGems ecosystem. This talk will cover extreme real-world examples from Rubyland and beyond, including code examples, footguns and award winners, as well as tips for developers navigating version management. It will get quite technical, so bring your regex hard hat.

De-mystifying the GVL

Josh Bebbington says:

The Global VM Lock is one of Ruby’s more mysterious ‘under the hood’ features. This talk explores new ways to peer inside it, using Ruby’s modern instrumentation to reveal how it actually performs work. I’ll demonstrate how we’ve applied those learnings at Carwow, to optimise the performance and reliability of our Sidekiq workers.

Afterwards

When the talks come to an end we’ll head to a local pub for some food, some drinks and some chat with your fellow attendees. Last time we were hosted by Bloom & Wild we visited Mc & Sons, just round the corner on Kennington Lane, which serves all the classic pub drinks to wash down some Thai food.

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.
