Malmö.rb meetup on 2019-02-05

Theme: First Ruby App!

The February meetup with Malmö Ruby Brigade has Lars Kronfält presenting tips for having a smooth experience when building your first Ruby app. We will explore a get-to-the-web journey where Lars adds user login to a small project.

Also: Jens Nockert will show an example of using FFI (foreign-function interface), extending Ruby with non-Ruby code.

We hope to meet you there!

Target Audience

This is a free event for people interested in Ruby.

We welcome both experienced programmers and total beginners to our events. In fact, we take great pride in making a welcoming atmosphere to newcomers to tech.

If this is your first time, you may find the How To Malmö.rb page helpful.

Planned Activities

We'll have a string of talks for you, interpolated by some snacks and time to meet the other attendees.

Lars Kronfält: Add user login to your app

As a website goes from idea to something you want to show to other people, you may find you want folks to be able to log in.

Lars has promised to show us how to add this, without very much trouble, but we asked him to explain the why of managing user data.

There will be some Ruby code shown. No game or Ruby experience required.

Jens Nockert: Show and Tell: How I used FFI

FFI means foreign function interface.

Jens will make it less alien, showing us an example of use.

This is a talk about extending Ruby's capabilities using the C programming interface.

Location: FooCafe, Stora Varvsgatan 6a, 211 19 Malmö

The location

FooCafe is at Stora Varvsgatan 6a, in Malmö. That's within walking distance from Malmö C where the trains stop. The building is a huge glass box. See also the FooCafe Malmö Location map page.

The location is on the ground floor, and doors open with motors. It is fully accessible to people with mobility issues.

When is it?

Just after office hours, say 17:30, and for about 3 hours. We try to keep the most interesting bits accessible to people who can not hang around too long, by placing them in the middle of the event's timeline.


There will be served a free snack in the form of a pizza. Details of that will be explained on the site, by the FooCafe host.

By the way: What is Ruby?

Ruby is a programming language which says it "optimizes for programmer happiness". We've started a separate Introduction to Ruby page, to get you up to speed.
