Beyond performance work, I deprecated a bunch of APis in the JSON gem, and added others, so I figured it would be a good occasion to talk about API design: byroot.github.io/ruby/json/20...

Thank you!

Looks great. Can you provide some details on how you built this?

Honored to be presenting at PGConf NYC in a couple of months! Hope to see you there. #postgresql

It was great chatting with you JP!

DuckLake: SQL as a Lakehouse Format DuckLake simplifies lakehouses by using a standard SQL database for all metadata, instead of complex file-based systems, while still storing data in open formats like Parquet. This makes it more relia...

Holy moly, it's amazing when things "just make sense."

This blog is SO good at pointing out what should have been obvious about AI for coding (Copilot and others)

These tools are good for re-creating whatever they’ve been trained on.

They are not what will create the next, better generation of frameworks, libraries, technologies.

If your team needs expert help improving performance, scalability, and reliability for your Ruby on Rails and PostgreSQL application, Refined Pages, LLC can help.

We'll systematically refactor Active Record ORM queries to optimize PostgreSQL performance.

The AWS option is using local storage for only temporary data but planetscale is using it for storage of all data. That's not really comparable.

As revealed at @tropicalonrails.bsky.social today, we are introducing an iOS app for @rubyevents.org to push and support the recent uptick in Ruby Events around the world.

If you've ever wondered how @rubycentral.org conference talks are decided, Noel wrote up a great thread about the process.

You tried both?

if you're on Mac try orbstack instead of Doctor desktop. It can be significantly faster

Congratulations!

> It's a thing you mostly get though practice I'd say.

I agree. I tell that to
people about ops. A lot of it is based on intuition/pattern matching which comes from practice.

I wasn't looking for a guide but about sharing more like the memory leak post.

CI topic is great. What I would also like to see

1. Investigating performance/memory issues using modern tools like Vernier

2. Not sure if this is up your alley but telemetry in production.

I’m still unemployed and looking for a new full time position doing Ruby, Rails, TypeScript, CSS.

If you know people who are hiring, I’d really appreciate an introduction. 🙏

Done with veto? Do you have a source?

OMG. This is too cute 😊

Cardboard? I thought 3D printers used plastic resin?

Here we go. That one I really needed to get of my chest for the better part of a year, so I feel relieved now.

It's really long but hopefully not too hard to follow.

Is there any company that publishes more self-critical and as-transparent-as-can-be postmortems than Cloudflare... within 24 hours of major incidents, should I say?

They've been doing it forever.

I personally trust them more for it. Eg from a few weeks ago:

Continuing my series to give context on Pitchfork design, why I think HTTP2 support isn't important (for a Ruby application server).

I really value that Tailwind CSS documentation uses real-world examples to introduce features 🫶

Those are much harder to produce than contrived examples, and the benefit is that they not only teach me library API, but also various strategies I can apply to my project 💯
