4/ Spent the week on real RSpec, on my actual 5-year-old production app — not toy examples. Hit real environment bugs, a couple of validation holes, and one Ruby/Selenium wall I had to name and move past. Full writeup: medium.com/@jamalamohamme…
3/ I would've sworn that field was protected. It wasn't — and the only reason I know that now is because I broke it on purpose and watched what actually happened. A validation existing in your code ≠ it catching the bug you assume it catches.
1/ Postgres doesn't treat two NULL values as duplicates of each other. I found that out by breaking my own app on purpose, during the first week I ever spent properly learning RSpec — after 10+ years of writing Rails with zero automated tests. #RubyOnRails
In my career, compilers have always generated better code that I ever could have. I find this to be increasingly so with contemporary AIs. But you know what neither can do better than me? Knowing what software to write, what shape it should take, and what I want it to do. The entire history of software engineering has been one of rising levels of abstraction. This is how it was, how it is now, and how it shall be in the fullness of time.

We're handling over 100,000 deployments a month now on @hatchboxio. Hatchbox started as a side project and has now become our core business. It's incredibly hard to bootstrap a product like this when all the competitors are VC-backed, but that didn't stop us from bringing
Kudos to @tnfoodsafety & @CollectorCbe for acting on my complaint vs @Anandhaas_cbe Kuniyamuthur. Insp done May 20. They missed plastic but caught 6 major violations (flies, open food, dirty floors) & issued a Sec 55 legal notice. Public safety matters!
Shocked by the food safety violation at @Anandhaas_cbe Kuniyamuthur (near Nehru College). Staff caught microwaving food in single-use plastic. A refund doesn't fix the health hazard. Reported to @tnfoodsafety. @CollectorCbe please ensure CCTV is audited. #ShreeAnandhaas #CBE
Real world savings from a real person. The proof is in the proverbial pudding!
Just finished moving my other product, Preceden, off Heroku and onto @hatchboxio. The great thing about Hatchbox is that because I already had a cluster set up for Emergent Mind, I was able to just move Preceden into it, so both apps now share the same DigitalOcean
True fact!
We've been around since 2016. Which is an amazing thing to be able to say. Over 2 million deployments across 24,000+ apps. If you're building something you want to still be running in the years to come, deploy with a platform that will be too. Hatchbox.io
My takeaways from This Week in Rails 🚂 ✅ titleize now capitalizes Unicode letters (é, ü, ñ, ć) — a small regex swap with big impact. ✅ AGENTS.md added to guide AI coding agents through the Rails codebase. world.hey.com/this.week.in.r… #RubyOnRails #Ruby #OpenSource
Rails app? Get in the App Store before work on Monday.
Ruby Native is now FREE until you ship to the App Store. Deploy your Rails business as a native iOS app and share it with up to 100 testers via TestFlight. 100% free. - Native tabs, buttons, & OAuth - Push notifications - No Swift, Xcode, or Mac required rubynative [dot] com
Yesterday Jekyll... today Bridgetown. Same server, different site!
For everyone asking, this was built with Ruby Native! rubynative.com
The first Ruby Native app is live in the App Store! - Native tabs - Sign in with Apple - Push notifications - And more, all backed by a Rails app + YAML I literally never opened Xcode. Not even for the screenshots.
This is now a reality. Ruby Native turns your existing Rails website into a native iOS app. Configure with YAML, preview on your iPhone, and ship to the App Store. Beta testers are getting apps in TestFlight the same day. And I am so freaking excited about it! Link below.
