🟥 Ruby 4.0 is officially released 🟥
Alongside the release, Ruby also introduced a redesigned official website — ruby-lang.org. The website redesign matters here more than it might seem at first glance. It reflects the same philosophy: clarity, approachability, and confidence built over time.
2025 was a special year with #ChicagoRuby, hybrid meetups, and Ruby events across the US — Sin City Ruby, RailsConf, XO Ruby, Rocky Mountain Ruby, SF Ruby Conf.
Planning 2026 is easy thanks to RubyEvents 👉 rubyevents.org
ChicagoRuby is taking a short pause in January — we’ll be back on Feb 4, 2026 with our regular monthly meetups.

⚡️ Tonight: Final #ChicagoRuby meetup of 2025
Planned talk is paused, but the meetup and Hack Night are very much on:
- more time to connect
- pairing, building, and experimenting with fellow Rubyists & DPI students
📍 6:00–8:30 PM
🔗 Intro stream: us02web.zoom.us/j/8579272577...
See you!
🔹 Ubicloud Demo at #struby — Open-Source Alternative to AWS
Dan Farina deployed Mastodon across VMs, Postgres, Valkey, load balancers, and subnets in minutes.
- Open-source cloud primitives
- Fully encrypted networking
Seeing Mastodon spin up live was a highlight!
🔹 @temporaltech.bsky.social Demo at #struby — Durable Execution for Ruby
Tom Wheeler demonstrated Temporal’s core strength: kill the process mid-task -> it restarts and continues without losing state.
“Your code focuses on the happy path. Temporal does the pessimism for you.”
🔹 NexHealth Demo at #struby — Healthcare Data Sync Engine
Matt Duszynski showed how NexHealth connects to hundreds of EHR systems (many borderline prehistoric).
- Normalizes inconsistent medical data
“The healthcare industry barely works… Healthcare technology is stuck in 1997.”
