Speaking to a specific person can give you a unique voice “younger me” is what I use often. And after enough words, a tone and style will fall out of it.p

mise now supports precompiled Ruby binaries (learned this from @nateberkopec.bsky.social's newsletter).

Right now you have to opt-in in the config file, but it will become default later.

See: mise.jdx.dev/lang/ruby.ht...

Happy holidays from RBQ Conf.

We’re grateful for all the early support, and excited to share our keynote speakers for March.

CFP is open for two more weeks if you’d like to join them on stage.

Rare tickets are still available.

I would love an RFD on this topic. I have my own thoughts on how to thread the needle.

"Let them relax" is kind of "fear of bothering co-workers" (in the extreme) and eventually at scale it is indistinguishable from a plain old moratorium. I think the details can make the difference

There are cases where I want it to error, I depend on this feature to prevent people from accidentally deploying to a different Ruby version.

Perhaps if deploying to production with BUNDLE_FROZEN then it should do a strict check.

Letting Puma auto-set your worker count is the easiest way to go for 90% of usecases.

Currently, you can only do that with WEB_CONCURRENCY=auto, but we'll also make this possible in the next puma version by using `workers :auto` in your puma.rb.

If you are using Concurrent.physical_processor_count or Concurrent.processor_count to set your Puma/Unicorn worker counts, that is wrong.

Use Concurrent.available_processor_count. It takes into account cpu quotas in envs like k8s/docker.

RBQ Conf is officially cookin’.

Our CFP is open, and we’re looking for sponsors who want to support a warm, community-first Ruby gathering in Austin.

Your #Ruby apps are now keep-alive ready! The years-long bug in Puma 6 has now been fixed, and we detail the architectural changes made to address it and how things should now speed up for you: https://sforce.co/47xdaMA

Upgrade to Puma 7 and Unlock the Power of Fair Scheduled Keep-alive Puma 7 is here, and that means your Ruby app is now keep-alive ready. This bug , which existed in Puma for years, caused one out of every 10 requests to take 10x longer by unfairly “cutting in line.” ...

I’ve resisted async this far. From the outside in it seems that cancel-ability is a fragile property and one that is niche. I’m also operating in an environment where allocations are fine.

Do you think there could ever be some kind of a reduced scope easy async?

What do you think of zig’s plans?

Missed opportunity to go as JJ Jameson.

The most valuable part of docs is the example. The worst part of an example is if it is wrong.

A doc test solves both these problems.

I want a default gem that all libraries can use. A standard for shipping examples with docs that are guaranteed to work

‘s about time to hit the road. Until next time #Austin.

I would like to see a rustdoc equivalent ship with ruby. And/or be able to link between existing tests and docs easily (think “expand src” but ”show usage in tests”

I am out in nature and on a farm.
