Happy Friday!

Ruby Garbage Collection in Under Two Hours is now available for preorder!!

Happy Thursday!

We’ll continue this mini email series with the next piece of the GC.stat hash: learning more about pages. As we discussed last time when learning about slots, pages are ~16kb chunks of memory, which each contain ~409 slots. Ruby requests memory from the OS in units of pages, and all of the pages together make up what we refer to as the Ruby Heap.

Hi!

We’re continuing this week with learning about another bit of the output of GC.stat. GC.stat is a hash Ruby exposes that can give us incredible insight into what the garbage collector has actually done when running our program. , we learned about different counts that gives us.

Hi!

If you’ve ever run GC.stat before, you’ve likely seen output that looks something like this:

Hi!

I’m trying a slightly new format for this newsletter, let me know what you think.

Recent GC work

I have two recent blog posts out in the :

Hi!

I just published the third blog post in the Ruby GC Deep Dive series about Ruby’s Generational GC if you’d like to read it. As always, feel free to respond to this email with any thoughts or feedback.

I’ve also started cross-posting my tips from Ruby Weekly onto the blog. Here’s one about and .

Happy Wednesday!

I’ve written the second blog post in the Ruby GC Deep Dive series, and I’d love for you to check it out. It talks about the main algorithm Ruby uses for its garbage collection, a Tri-Color Mark and Sweep algorithm.

In case you missed it, in this series, which discusses internal constants used for Ruby’s GC.

Hi!

First and foremost, thank you for subscribing to this email list. I’m incredibly excited to share my work with you. I’m always open to feedback – just reply to this email!

I’m writing a series of blog posts around Ruby GC, and I’ll email this list each time there’s a new one. I’ve just written . I used the internal constants to give a description of the heap, pages and slots that make up the skeleton of Ruby’s GC.
