My @sfrubyconf talk on real-time collaboration with AnyCable, YJS and Rails is up! I felt really happy with how it came out - let me know what you think because I can't watch myself talk 😂

Super cool news tonight: Rails realtime now runs on the server of your choice 🔥🔥🔥
Vova’s Action Cable server adapterization PR was merged 🥳. Same Channel and Connection code, swappable runtime underneath: Falcon, Fibers, async-cable.
This is the groundwork AnyCable has been proving in production for years, now landing in Rails itself.
People credit Rails’ longevity to DX. I think the secret behind it is adapterization pattern: every layer hides a default behind an interface, so the framework absorbs each new wave of innovation without a rewrite. Others wire it up with extra services. In Rails you swap the implementation as you wish, keeping the code intact.
Two years in the making, with
@ioquatix, @matthewd and @rafaelfranca steering the reviews. Congrats @palkan_tula 🥳

The hardest part of being a developer isn't the code, it's learning that the entire internet is put together with peanut butter and goblins.

It's in! Also apparently my first Rails contribution, that's neat
Currently in ActiveJob, `wait` in `retry_on` accepts a proc, but it is only handed the execution count. I think access to the error can also be useful when calculating the next wait time. If you agree, give it a like! github.com/rails/rails/pull/…

It’s late, and you get alerts that web requests are failing. Page loads hang endlessly. The server isn’t responding, requests are queueing up. What do you do?!
"When good threads go bad" is a deep dive into stuck threads, how to deal with them, and what to avoid.

My favorite talk!! @jpcamara used Yjs and @any_cable to build a collaborative text editor in a Rails app, and it was super fun trying it out live with other folks during his talk.

TIL if you want to return the duration in seconds, returning it as an Integer is a _hard_ requirement
There is a _specific_ check that the class is Integer. If you accidentally return a float, Sidekiq ignores it and reverts to its built-in delay policy. Be careful!
