XO Ruby joins RubyConf as Another Exclusive Discriminatory Unexcellent Conference

Tue, 11 Aug 2026 20:14:20 +0000

So, I got contacted by the organizer of the XO Ruby conference (aka Travelling Ruby), Pascal Laliberté, on meetup.com because I organize the Montreal.rb Ruby Meetup and am a Montreal-based Expert Ruby Software Engineer. He said XO Ruby is coming to Montreal and asked me for help with it. We end up meeting in a video conference call… https://andymaleh.blogspot.com/2026/08/xo-ruby-joins-rubyconfrailsworld-as.html

sghtmltopdf: an HTML to PDF renderer in Rust, with a Ruby gem and Rails integration

Sun, 09 Aug 2026 08:13:15 +0000

wkhtmltopdf was archived in 2023, leaving Rails apps stuck between an unmaintained binary and spawning headless Chrome. I built sghtmltopdf, a new rendering engine written in Rust that implements CSS Fragmentation and @page directly, so page breaks, orphans and widows are first-class rather than approximated. It ships as a CLI, an HTTP server, and a Ruby gem (gem "sghtmltopdf").

What Active Record Transactions Actually Protect

Sun, 09 Aug 2026 05:57:42 +0000

An Active Record transaction traced across one database connection, retained model state, remote side effects, false returns, non-local exits, nested transactions, savepoints, and PostgreSQL statement failures.

Solid Objects: Easiest reactive ERB there has ever been

Sat, 08 Aug 2026 14:22:08 +0000

I’ve been building Solid Objects, a gem that brings the Durable Objects programming model (addressable objects, durable state, serialized turns) to ordinary Rails applications. It runs on the MySQL, PostgreSQL, or SQLite database the app already has. No Redis, no Cloudflare account, no separate actor service.

Turbo Drive, Frames and Streams: a reference verified against the source

Fri, 07 Aug 2026 19:18:58 +0000

Turbo’s documentation is complete but unconnected: Drive, Frames and Streams sit side by side with nothing saying what links them or how to choose. This is the reference I wanted when I started, written by reading the source of Turbo 8.0.23 and turbo-rails 2.0.23 rather than the docs, because that is where the gaps are.

Running a Ruby MCP Server in Production

Wed, 05 Aug 2026 19:20:05 +0000

In this article, Amanda goes through what a Ruby MCP server needs once it stops being a subprocess: Streamable HTTP instead of stdio, a choice between a standalone service and an endpoint inside an existing Rails app, statelessness so it survives more than one Puma worker, Host and Origin validation that a security advisory made mandatory, a shared token as the internal floor with OAuth as the answer beyond it, and read-only models and server_context deciding what any caller can actually reach.

Wide Events: Token-efficient Rails telemetry for coding agents

Tue, 04 Aug 2026 20:29:00 +0000

I released Wide Events, a Rails gem that records each request or job execution as one dense, high-cardinality telemetry event. It gives coding agents queryable production context without making them reconstruct what happened from scattered logs, spans, and metrics. Agents can retrieve only the relevant rows and fields for a route, account, build SHA, feature flag, or error, keeping the context compact.

What Happens When You Call save

Sun, 02 Aug 2026 03:57:53 +0000

An Active Record save traced from pending dirty state through validations, callbacks, persistence, and its transaction wrapper. It explains false returns with empty errors, validate: false, callback-chain inspection, successful no-op saves, and why a failed inner save can leave other work committed.
