@k0kubun I'm excited to see this talk or even just hear the next sentence after this !

Ruby is faster than C #rubykaigiA

@Matt_Pinner You can subtract the 1 before or after you add 30.

How do you calculate 56+29 in your head without a calculator? Indulge me please, I am trying to check something

@nateberkopec Amazing collaborating with you at the Performance Guild! Let me know if you have any parting wishes or things you'd like me to look out for.

@dbxdigital I feel like hub.com and lab.com don't have the same ring to them. Maybe travel back in time / swap dimensions and fork Git for posterity?

Git doesn’t exist. What’s your choice?

@aarondfrancis Redis "it just works"

Guess I won't be cooking quite as much as I thought! I expected it to be at least... three times this size

If you talked to me when I first joined Gusto around a year ago, you’d know one of my biggest aspiration was to get the company to invest in the Ruby and Rails community. AND ITS FINALLY HAPPENING! @GustoHQ is a proud sponsor of @railsconf 2024 🎉

@julienbourdeau What I regret most about Atom is that it's been discontinued :( :( :( Still the best editor made. I'll keep looking.

- Notepad++ (until 2010) - Sublime Text (2010 - 2015) - Atom (2015) - PhpStorm (2016 - 2018) - Intellij IDEA Ultimate (2018 - forever) PhpStore to IntelliJ isn't really a change, it's just a better version. I regret switching to Atom, there was NO advantages over Sublime Text.

@jnunemaker Looking forward to meeting you in person there!

Seeing all these railsconf acceptance posts makes me happy for everyone and kind of bummed I waited until the last minute and then forgot. 😂 I should still be there. At least I won’t have speaker nerves like you all!

@excid3 @railsconf Can't wait to hear your talk Chris!

Excited to see you all at @railsconf in May!

@ecyrbedev @GregMolnar Collision is not nearly as big as a concern as the Performance hit (across both production and your data lake). But if you don't care about scale, its fine.

@GregMolnar Your chances to get a duplicate is 1 in the lifetime of the universe. And if you are concerned, roll your inserts in transactions so that they'll run again in case of failure. UUID are good for distributed databases, for preventing predictable attacks, to allow parrallelism.

Do not use UUID for primary keys.

@fatkodima Serious question: how was Marginalia slowing down your tests? All that from string overhead?

Testing performance tip: The easiest way to find out why the tests are slow is to profile them. No other tools/gems except the profiler is needed. Doing this, I was able recently to speed up tests by ~30%⚡️! Turned out, marginalia and a password related gem were the culprits.

“It turns out, confidence has an inverse relationship to the breadth of work being done. Change a lot of things and confidence plummets.” — @BenNadel Tiny pull requests (thanks to feature flags) make for happy developer minds (for creator and reviewers) and happy customers.

@jnunemaker @flipper_cloud Are you actually using tzinfo-data or is that left over from installing?

For fun, here is @flipper_cloud's gem file: gemfile.directory/gemfiles/66f4d… Any surprises in there?

I just wanted to try out TinyZap making this link look cool tinyzap.co/IsdznQ

@chris_mccord I'm partway into answering my own question via this: dashbit.co/blog/you-may-n… Now I think I know what the meme is about. But even then I see Redis-Phoenix adapters out there

@chris_mccord wait, who killed Redis and how did they do it? (I'm Team Redis all the way)

@jnunemaker I just joined the board of Ruby Central. I'd love to get your advice, if you'd be up for getting some time together.

@imgyf Eggs.

If GitHub was founded with Ruby on Rails, and Ruby on Rails is hosted on GitHub, which came first?
