we're back with another remote-friendly Ruby User Group! The time is 19:00 CEST so that's 17:00 UTC or well 5pm UTC.
You're welcome wherever you're from as long as you adhere to our Code of Conduct - the meetup is in English.
Current schedule is two ~20min talks including Q&A, followed by splitting the audience into smaller groups for virtually hanging out (optional) :)
Joining the meetup
Meeting ID: 966 0613 1778
The meetup will be on zoom and it will be recorded
- if you don't want your video to be visible to others, then turn it off/leave it off
- if you can't make it/don't want to be on zoom, watch the recording!
We're aware of the privacy concerns surrounding zoom and we share them. We're looking for better tools, we haven't found them yet.
Meanwhile, if you don't want to use the desktop client the zoom browser link above should work for you. If it doesn't you can usually get to it like this: the join link should also show a tiny "join from browser" link at the bottom of the window. It doesn't appear to require an account anymore. If the link doesn't show up, open the "Download and Install Zoom" link in a separate tab, that should make the link appear. Dark UI patterns 😖
Participating in the meetup
- We'll take Q&A questions in Zoom via the "raise hand" feature (click on participants, there's a little raise hand link)
- There is also a #rugb-live channel in the Ruby Berlin Slack, you can join the slack here
- the "socializing" part is optional, naturally, our aim is to not lose that part of our meetup - we'll try to use Zoom's breakout feature to split you into random groups and give you some ice breaker questions to kick it off
Your feedback is very welcome. Things will go wrong, we'll try to fix them.
Looking forward to see y'all Rubyists from Berlin and maybe all over the world.

This talk will discuss what happens to objects as they make it through their lifecycles. It will discuss the Ruby Heap and give an overview of different aspects of garbage collection including incremental gc, generational gc, and compaction.
Functional Programming in Ruby with Lambdas
Object Oriented Design is powerful for organizing software behavior, but without the benefit of lambdas' code-as-data flexibility, in many cases it fails to reduce solutions to their simplest form.
Functional programming has been gaining popularity, and many Rubyists have embraced functional languages such as Elixir and Clojure. While Ruby generally isn't considered a functional language, it does have lambdas and a rich Enumerable library.
Although Ruby's Enumerable functionality is widely appreciated and used, its lambdas generally are not.
This presentation introduces the developer to lambdas, and shows how they can be used to write software that is cleaner, simpler, and more flexible.
We'll go through lots of code fragments, exploring diverse ways of exploiting the power of lambdas, and identifying reusable functional design patterns along the way.
Keith Bennett (web site, Twitter, Github) is a long time software developer in the USA who started his software development career writing an in-house accounting package in Applesoft BASIC on an Apple II, and has since worked primarily with C, C++, Java, and Ruby.
He spent most of the four years preceding the pandemic living in Asia but is now hiding out in his Reston, Virginia apartment awaiting the opportunity to travel again.
His other interests include technical community, current events, foreign languages, karaoke, and becoming a better human being.
