Scottish Ruby User Group


The Scottish Ruby User Group is a collection of people who are linked with Scotland and have an interest in Ruby and Ruby on Rails.

We meet every month online and in person in Edinburgh for presentations from members and guests, and a chat about Ruby and related subjects.

All are welcome, and there are no subscriptions or costs involved.

Meetings are announced in advance on the mailing list, Meetup, and Google Group and follow our code of conduct.

You can also find us on:

Meeting up

We currently meet online on the second Thursday of the month at 18:00. Currently we’re experimenting with the most appropriate video conferencing solution. Links will be posted the day before if you’re signed up on Meetup.

Mailing List

You can browse and subscribe to the list using the ScotRUG Google Group information page. The list is for announcements of activities and general Ruby support and discussion; feel free to post any questions you may have.


We have a Freenode channel #scotrug, though it’s quite quiet. There’s also the Gitter channel around the ScotRUG github repository. It is also quiet.

Code of Conduct

To ensure we provide a welcoming and friendly environment for all, attendees, speakers, organisers, and volunteers at any ScotRUG meetup are required to conform to our code of conduct.

Organizers will enforce this code throughout the meetup and meetup-related social events.

Where and When?

Our Edinburgh meeting in October will be in our alternate venue: FreeAgent have offered to host us on Thursday the 10th, at 18:00. That’s in their Edinburgh offices on Fountainbridge.

The 10th will be special! FreeAgent will be showing a talk from Inclusive Design 24. The talk will start at 17:00 and you are more than welcome to come along. ScotRUG will start at 18.00 as usual.

If you arrive early for the Inclusive Design, you can enter the building and sign in at reception, then ask to be let up to FreeAgent. For those who will just come for ScotRUG, someone will be downstairs to let you up. Otherwise contact us on twitter: @scotrug, or send an email to the list. We’ll come and get you!


The wind is blowing, snow is forecast on the hilltops and the sun is fast disappearing. Winter is coming. Still, it’s a good time to be in Edinburgh. The winter festival to look forward to, Samhuin to enjoy and the best local food.

Last month we went over Ruby MRI, how the underlying C code looks. This week we will be looking at JRuby and how it compares to MRI Ruby. There is a great talk from Charles Nutter and Thomas Enebo which we will be watching. Let’s see where that brings us! ScotRUG welcomes first timers and regular attendees, whether you’re new to the language or not. We’d love to see you there!
