**Crystal: Ruby with Static Typing [1h] - \*\*\*Speaker(s) To Be Decided\*\*\***

Crystal is a relatively new programming language that aims to emulate Ruby's syntax as much as possible while supporting Static Typing.

Although Ruby remains the most convenient and productive programming language for business app development due to handling types automatically with Dynamic Typing, in about 1% of Business Software Development cases, Crystal can help out when there is a need for much higher performance in response-time-sensitive and performance-intensive computations.

In a recent RubyConf keynote speech, Matz (the creator of Ruby) compared using a Dynamically Typed language like Ruby to driving a car with an automatic stickshift and using a Statically Typed language like C to driving a car with a manual stickshift. Most of the time, the convenience and productivity benefits of automatic stickshift are more desirable to deliver value in a timely fashion to customers. But, every once in a while, driving manual could be a very useful alternative for the few cases that need it. As such, it is valuable to learn Crystal for the sake of augmenting Ruby with a language that trades off some programmer friendliness for performance whenever needed.

This talk will provide a general overview of the Crystal programming language and show some Crystal code examples.

**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 $13 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.
* **7pm - Talk - Anticafe Place Des Arts**
* **8pm - Networking Time - NYKS Bar** (1250 Rue de Bleury, Montréal, QC): Networking time continues at 9:00pm (if we don't find seats at NYKS Bar, we could meet at Benelux at 245 Sherbrooke St W instead).

--
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](https://www.youtube.com/@montreal-rb) if talk speakers agree.
