Had an incredible time at @sfruby.com
Fantastic talks, amazing people, and great vibes across the board
So much to dig into and unpack around tooling, AI, development patterns and our collective ownership in the future of Rails
Community day was such a great finish

I'm not sure @ankane.bsky.social is human - maybe some kind of open source being from the future 😂
I said to a colleague - "we'll see, but it's ankane, so it's entirely possible it'll get done soon". Less than an hour later, it was updated 🤯

4) "When good threads go bad" coming soon!
Dan shows how jobs are executed in the `process` method, which has this hefty section utilizing `handle_interrupt`. He does a great job describing how it works, and my next article will dig deeper into if you're interested!

If you read my article on ruby thread interrupts and bitmasks, this will be very familiar! jpcamara.com/2025/10/22/b...
I asked koichi if signals were the inspiration, and he confirmed it. It was fun to see the connection and what can be an inspiration for central language apis!

You can change the default return value of a hash by using `default=` on the hash. docs.ruby-lang.org/en/3.4/Hash..... Now instead of nil, you'll return whatever `default` you provided! Very handy.

1) @mike.contribsys.com you clever devil, that Signal.trap approach is ingenious!
In my post on thread interrupts, I mentioned that you cannot use rails.logger inside of a signal.trap: bit.ly/43c23Ym. Similarly, you cannot use the Sidekiq logger in trap, which is inconvenient.

Incredible validation for Falcon as a Ruby web server, and for Async in Ruby. I spoke about concurrency at last years RubyConf and had to call out Falcon - it's the server i've been most excited about in the past few years.

I've been reading Ruby Weekly since - let me check my inbox - *SPITS OUT WATER* - 2013?!? And that was already the 126th edition 😱 @cooperx86.bsky.social you are a machine!!
It's always been one of my top Ruby resources, so it's extra fun to be included in it!

It turns out the tiny /o modifier has an outside influence on how your program runs. It creates a permanent, immutable version of your regex after the _first_ time it runs. My personal policy from now on is to never use this modifier. Ever. I dig alot deeper in the article, give it a read!

If you read @byroot.bsky.social 's "What's the deal with Ractors?", and were bummed at how poorly they handled JSON parsing, then @jhawthorn.com has brightened your day!
Frozen interned strings are now stored in a lock-free hash, making the Ractor example 2x faster than the single-threaded example!

I’m a little bummed, but I think my RailsConf talk getting declined is for the best! I can focus on getting back to blogging and also just enjoy the conference without revising my talk endlessly.
Should I still submit it as a talk elsewhere down the line? Would you go to it?
