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 🥳

@inazarova Massive congrats @palkan_tula and @ioquatix !

Every engineer should read this.

The principles for building reliable software systems have been around for a long time. Max outlines them beautifully.

Here's to getting that 99.99% on your status page.

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.

Unbelievable validation for Samuel’s vision

@brandur Finally!

[jpcamara @jpcamara]

@opencode Still not seeing it in Zen

[jpcamara @jpcamara]

@paolino @bradgessler Yea @_byroot put a ton of work into that, it's a huge win. I seem to remember seeing that 8+ does it... better? But it is a part of Rails 7.2 as well.

[jpcamara @jpcamara]

@paolino @bradgessler I think this + my batch support work https://t.co/42frT26HBT would be a crazy unlock for being able to coordinate IO workloads/LLM interactions. Fully parallelized tool calls with a batch checkpoint at the end

[jpcamara @jpcamara]

@amorriscode Yes please!

[jpcamara @jpcamara]

@bradgessler pffft, call me when you're at 38 gigs 🤣

[Garry Tan @garrytan]

I think people are sleeping a bit on how much Ruby on Rails + Claude Code is a *crazy unlock* - I mean Rails was designed for people who love syntactic sugar, and LLMs are sugar fiends.

SaturnCI is looking better and better, if I do say so myself.

[jpcamara @jpcamara]

@BenjDicken big theo energy. extension sounds amazing! would love to see the source at some point

[jpcamara @jpcamara]

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! https://t.co/dZwAaZtfhr

“It’s 10pm, do you know where your children are?”

I added this to my “when good threads go bad” post

Does anyone else remember these ads?! May have only been a USA thing

[jpcamara @jpcamara]

Finally got it released, just before the new year 🥲

[jpcamara @jpcamara]

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.
