The September 2023 meeting of LRUG will be on Monday the 11th of September, from 6:00pm to 8:00pm (meeting starts at 6:30pm).

This month we're hosted by the lovely folk at Smart in their offices on 136 George Street. Full venue and registration details are given below.


The Functional Alternative

Ju Liu says

We'll start with a simple Ruby Kata and solve it together, live, with imperative programming. We'll then fix the many, many, many things we got wrong. Then we'll solve the problem again using patterns from functional programming. You'll leave this talk with a clear and concrete example of why functional programming matters, why immutable code matters, and why it can help you writing bug-free code. The next time you find yourself writing imperative code, you might consider… the functional alternative.

Back in my day…

Paul Battley says

I've been working with Ruby since the early 2000s. Ruby has changed a lot in that time, but we don't always remember how much. Let's rewrite a short program so that it runs in a twenty-year-old version of Ruby and see how much syntax and performance has changed for the better in twenty years

Once we're done with the talks we'll leave the venue (after doing our best to help tidy up) and find a local pub to visit so we can eat, drink, and discuss the talks we've just heard.

Of course, even though this is the socialising part and seems more informal, please remember that still we consider it to be a part of the meeting and covered by our code of conduct.
