Vibe-coding a chess app with my Ruby Event Sourcing and reactive web app libraries. All interaction is server-rendered, which makes things like highlighting legal moves simple. And time-traveling, of course, because always show off if it's easy!

I may have gotten a bit carried away with this work github.com/ismasan/side...

Great in-depth article on how PHP's Ecotone framework scales event-sourced projections. This is very similar to the design I arrived at. IMO partitioned event reactors are non-negotiable. blog.ecotone.tech/when-one-wor...

Sidereal's scheduled triggers (WiP) are 🔥. You define when commands are dispatched, on a fixed or recurring schedule. The example is a bounded schedule that starts 20 seconds after boot, recurs every 3 seconds, and ends 10 seconds later.

I've been working on three different Ruby libraries that solve (in my mind) different problems, but together make for my dream toolkit. Sourced - event sourcing and workflows Steppe - self-documenting HTTP APIs (and MCPs) Sidereal - command driven, reactive apps I have a clear integration plan now

Huge news for our corner of the Ruby world, and the culmination of a multi-year effort to align our people, our code, and our presence on the web. Go check out the new site, it’s stunning! Deepest of thanks to @aaronmoodie.com and @makenosound.bsky.social for co-creating these wonderful visuals. 🙇

Sidereal's built-in filesystem store now supports scheduled commands, and retries with exponential back-off built on top of them. All done via Ruby fibers and atomic file renames.

This simplifies most of the things I've been patching together for the last year honker.dev

Sidereal's built-in filesystem store now supports scheduling commands to run later. Here, starting a donation sets a command to run X seconds later.

Working on filesystem-backed Store and Pubsub implementations, so that out of the box Sidereal works across multiple processes. Goes well with SQLite for your own data. Later I might add optional networked implementations (Redis, NATS, etc)

A command-based web framework means you can send commands to the running app from anywhere, and the UI will just update accordingly. Down with the tyranny of the request/response cycle!

Listen to this man!

I had a great time at Haggis Ruby in Glasgow. My (first) Event Sourcing and Ruby workshop packed a little more material than the time permitted, but I hope it was useful to people! Big thanks to James and the organising team.

Two weeks of (intense) family holidays followed by two conference talks in a row. This will be an April to remember.

Last week’s talk at @wrocloverb.com is already up (that was fast!). Building reactive systems with Ruby and Event Sourcing. Big thanks to the team! youtu.be/Q6owchf4WEo

The landscape on the way to Scotland is just so ridiculously postcard-pretty. I want to get off the train at every random little village and just walk around for a day.

Off to Haggis Ruby in Glasgow!

This is a great summary of the zeitgeist I've been exploring in Ruby for the last few years. It feels like it's just the beginning! dev.to/siy/the-quie...

This is the model for a demo app I used for my Event Sourcing talk at @wrocloverb.com . Simple, explicit step-by-step flow threading together all parties to a workflow, from backend to UI screens.

You can rebuild state from events. But you can't rebuild events from state. Think about football. If you see 2-1 on a scoreboard, you know the current score, but not how it got there. That's the problem Event Sourcing solves: www.youtube.com/watch?v=xPmQ...

Just use a queue justuseaqueue.com

Compilable event models. What an ambitious project! www.weltenwanderer.dev

This will always be present day science fiction to me

I’m never late to airports anymore. Is this what being an adult feels like?

My event sourcing talk at @wrocloverb.com went well, I think! At least I didn’t trip on a cable on stage, or anything.

Running last minute checks before my talk, such as “is my zip open?”

Never in the history of coding have a library's bugs been fixed as quickly as two days before the conference talk about said library.

I’m in Poland at a self-service restaurant. I don’t speak polish. No idea what I’m eating, but it’s delicious

That moment when you have to travel super early in the morning and your jet-lagged child refused to go to sleep until 2:30am the previous night.😴

I've said the world doesn't need yet another web framework and yet here we are, writing one. Said that, it's feeling pretty nice to be able roll-out reactive, realtime apps so easily in Ruby.

Modelling flows via LLM and Eventlanes.app continues to be pretty awesome

8yo’s origami skills are off the charts

Open Twitter. See post about the Earth being flat. Close Twitter.

Gargantuan parrillada right before a 17 hour flight. Always a great idea.

As well as the southern sky. Also: a smartphone shouldn’t be this good at night photography, what’s going on!

Southern Chile epic as usual.

Haggis Ruby's is in just over a month, in the wonderful city of Glasgow! Get your tickets here: haggisruby.co.uk We're lucky to have an incredible list of speakers from across the community. If you want an idea of what the talks are like, videos from 2024 are here: www.youtube.com/@HaggisRubys...

Great academic debates in this household. - 6yo: "For something to be alive, it needs to have atoms" - 7to: "That's not true! For something to be alive, it needs to go to the toilet!"

Ok, a very simple TODO app, real-time and multi-player, in Ruby.

Project Hail Mary was pretty great

Aaand... It's working.

I think I’m nerd-sniping myself into building a CQRS-first, real time, durable execution by default, start-on-a-single-file web framework for Ruby. I kinda already have all the different pieces in different places.

I finally started exploring APIs for defining server-rendered page objects that react to events and render themselves.

Death just chuck-norrised.

Adding Brotli compression to the Ruby Datastar SDK (compresses SSE streams). First naive benchmarks, but the compression ratios are 🤯

Cinema-booking demo for stream-less Event Sourcing going well. Helps find APIs and perf. to tweak. Demos are great dog-food!

Keynote Klaxon! We’re delighted that @mikemcquaid.com will be opening Haggis Ruby for us this year. Mike’s the CTPO of Administrate and the Project Leader of Homebrew. Get yer tickets to see him here: haggisruby.co.uk

Did you know? You don’t always need to pick a side. It often happens that all sides are, in fact, absolute assholes.

To this day, one of the dumbest design decisions in the universe
