Details
Event Timeline:
- 6:30pm - Pre-talk Networking Time - Anticafe Place Des Arts (294 Saint-Catherine St W, 3rd floor, Montreal, QC): this is a coworking space, so the event costs about $10 that covers drinks like coffee/tea and snacks like chips/pretzels/cookies; sign in on Anticafe's computer when you enter and pay Anticafe for your stay when you leave; after signing in, go to the 3rd floor*, turn left, and then walk to the presentation room with the projector screen*. The venue is a coworking space, so its employees might not know about the event. Contact the organizer, Andy Maleh, via DM if you get lost or have questions.

- 8pm - Networking Time - NYKS Bar (1250 Rue de Bleury, Montréal, QC): Networking time continues at 8:30pm (if we don't find seats at NYKS Bar, we will meet at Benelux at 245 Sherbrooke St W instead).
Temporal Tables in ActiveRecord [1h] - Martin Giannakopoulos
In relational databases, a temporal table is a type of table that tracks changes and permits point-in-time historical queries. Temporal tables were added in SQL:2011 though few RDBMSs implement them. The talk will go over the concept of temporal tables, how to implement them in PostgreSQL, and finally how to use ActiveRecord to make working with them easier.

If you have a Ruby talk idea you would like to present at a future Montreal.rb meetup, please contact the organizer (Andy Maleh) to get your talk scheduled in an available future meetup month (it is also possible to bump talks by organizers of the group into later months to take one of their month slots for your talk). You can also contact the organizer if your company is interested in hosting a future Montreal.rb meetup at their Montreal office. Note that speakers must present in-person in Montreal because the goal of the meetup is to encourage more in-person networking and socialization around Ruby Software Engineering topics with maximum communication bandwidth. Talks are recorded and posted on the @montreal-rb YouTube Channel if talk speakers agree.
