🚀 Kicking off Saturday with a pop! 🌟 Dive into the world of Ruby with our Day 2 opening keynote by Jemma Issroff (@jemmaissroff) titled "Popping into Ruby". Hear from one of Ruby's Core committers, ✨ Sat, Oct 7, 9:10. #rubyconfth #ruby Full Schedule: https://t.co/QnwPdeYNNQ

We're delighted to announce @jemmaissroff as our third keynote speaker! Jemma is an expert on Ruby and Rails infrastructure, founded wnb.rb, and wrote a book on garbage collection! We're excited to welcome her to Bangkok this Oct! Tickets on sale now at https://t.co/DQN1rIPokT

For those attending @rubyconf_au we’re going to do an in-person meetup on Wednesday February 16th at 6pm. 🎟️ We’ll meet at Polly Woodside Park and have some snacks and can walk to the conference-wide Kingpin afterwards.

@rubyaustralia Do you want to learn how object shapes work, why we implemented them for Ruby 3.2? If you're curious to learn more about Ruby internals, or how instance variables work, @JemmaIssroff has the talk for you!

I'm heartbroken to share this news about our dear friend and colleague, @ChrisGSeaton.

Now that I am waiting to board my flight to Houston, I can't help think about the great experience everyone had at #RubyConfMini a little over a week ago. It was one of the best conference experiences I've had and here is why: 🧵

Today @jhawthorn merged a PR that changes Classes and Modules to use object shapes for storing instance variables rather than a hash table. Class IVAR reads are 2x faster, and it saved 16MB RAM! 👏

Someone asked if @RubyConfMini was still accepting talk proposals. I don't actually know of any way to check which Ruby conferences currently have open CFPs. Does anyone know of a resource that would say which CFPs are currently open?

We’re not guaranteed that the removed ivar is the last one, and so can’t just re-use the last index (which is what we’d do if we decremented iv_count). For example:

Also, I got a question about iv_count on the undef shape a few times, so wanted to answer it here if anyone is curious! Yes, it was intentional that iv_count didn’t decrement on undef shapes. iv_count is used as an index into the object’s instance variable array ...

Speaking at @euruko was the best I’ve felt on stage yet. Thanks to all for watching, and the generous feedback. Can’t wait for next year! https://t.co/FamDXzrt5q

If you were at @euruko please test for covid. I've heard of several cases so far. Please also tell anyone who might not see this. Sorry to be the bearer of bad news, and hope those who are positive feel better soon!

Who should I be chasing to find sponsors for RubyConf mini? Are you looking to find (or sell to) excellent Rubyists of exquisite taste? Sponsoring mini would seem like a no-brainer to me. Emails are open: andy@goodscary.com

It's a great day to have a great day! Also a great day to register for @RubyConfMini, and join us in Providence mid Nov to meet other Rubyists IRL, watch talks on a wide variety of topics (and meet the speakers / keynoters), and engage with our sponsors

A list of many many people I admire. Can't wait

Registration to RubyConf Mini is now LIVE! 🥳🎉 We're so excited to see you all in Providence, RI! https://t.co/5fbViHkC8X

underused Array method: bsearch. If you're `find`ing on a sorted array... you could probably bsearch and it'll be faster. Of course @JemmaIssroff already wrote up a great guide:

Also, the designs of the keynote graphics are all the work of @EmilyGiurleo

The hope with doing this was that each keynote speaker would get the praise / attention they deserve. One keynote in and already seems to be panning out! Maybe we should do this style release for non keynote speakers too??

Our first keynote speaker is.... 🥁🥁🥁 .... @rose_w!!! 🎉🎊 She's a Senior Staff developer @shopifyeng and an active Ruby community member. It'll be her first ever keynote. We can't wait to see it!
