Static Ruby Monthly
The only newsletter dedicated to static typing in Ruby
|

|
Hey there!
Here is the first edition of my newsletter dedicated to the static typing world in Ruby. I find this as important as testing when writing robust software in dynamic languages like Ruby. Luckily, we now have several ways of doing it, so one can pick what they like the most.
As this is the first edition, I focused more on finding guides and content that help you get into the topic rather than the highlights of what recently happened in the static typing world.
You can find all the previous editions of the newsletter in my archive.
Cheers,
Andrey
