Get in, human: cut Rails boot time with require-profiler and this guide

Wed, 19 Aug 2026 15:02:19 +0000

Rails boot time is a DX metric now. Every restart costs deploys, CI, and human attention. And agents boot apps way more than people. So, our convenient new require-profiler gem shows what happens during boot: requires, Rails initializers, YAML parsing, HTTP calls. Run it, then drop to a sampling profiler for what the tree can’t explain. One 200-component monolith cut development boot time by 40%.

Sun, 16 Aug 2026 12:51:19 +0000

Traffic Generation: How to Drive Search Traffic to a New Blog Without Buying Backlink

Sat, 15 Aug 2026 10:22:22 +0000

Omakase 0.2 — agents as plain Ruby objects

Fri, 14 Aug 2026 03:56:28 +0000

I released Omakase 0.2, a small agent framework on top of RubyLLM about 800 lines. The idea is that an agent is an ordinary Ruby object: its fields are state, its public methods are what the model can call (no tool registry, no JSON schemas to keep in sync - describe above a method is the description the model reads), and the methods you declare without a body are written by the model at runtime. The return type is the contract: a schema block gives you validated data, a scalar unwraps to a value, and a Ruby class means the method hands back the object your code built - under the default :code_act strategy the model answers by writing Ruby that is evaluated on the agent itself and calling finish(value), so the answer is computed rather than retyped as JSON. There’s also :predict for one-shot structured output, MCP servers and SKILL.md directories that arrive as methods, per-method model selection, attachments, and a FakeChat so agents can be tested without a network. The transcripts in the README are from a 30B model on OpenRouter rather than a frontier one, on the theory that a strategy which only works on the biggest model available is a demo and not a library. The docs cover the Rails side - agents in app/agents, jobs, multi-turn built from your own tables - and are blunt about the fact that generated code runs with instance_eval, so untrusted input belongs to :predict unless you swap in your own executor. MIT, Ruby 3.2+.

Updates to Testing Rails from Scratch book

Thu, 13 Aug 2026 20:51:38 +0000

Hi, I’ve pushed some updates to my work-in-progress book on using Rails defaults (mostly) for test-driven development, based on my approach and opinions from using RSpec for 15 years. The updates are now available on Leanpub, and I wrote a quick post on Left of the Dev to share what’s available now and what’s next. Thank you for your support!

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").

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.
