intertwingly.netWhole Routes in a Box

Whole Routes in a Box: the hope/plan is to enable moving an application from Rails to Roundhouse one route at a time. intertwingly.net/blog/2026/10...

intertwingly.netMany Keepers

DHH opened Rails World by saying what he believes, plainly. He also asked us to be optimistic, and I am, about Rails in particular. Today I open the second day of Deccan Queen on Rails, and I hope I clear the bar he set. intertwingly.net/blog/2026/10...

Agents make producing code nearly free. Where a project has a good oracle, trust is cheap too, and the pace becomes an asset. Where it doesn't, every contribution has to be verified by a person, and the pace becomes overwhelming. Spinel has Ruby. Roundhouse has Rails.

intertwingly.netRust is the answer to the wrong question

100% written by a human. Porting and on-shotting are anecdotes. Yes, Rust is faster than CRails. Duh. But is that really the interesting question? What happens when your needs change and you are faced with a requirement than you never anticipated before? intertwingly.net/blog/2026/09...

intertwingly.netNokogiri, Loofah and Crass, Compiled

Nokogiri, Loofah and Crass now compile to native code with Spinel, Matz's Ruby-to-C compiler. Same requires, same APIs, no Rails. An HTML sanitizer becomes a 2–3 MB binary that runs in 5–9 ms, byte-identical to the gems on their own test inputs. intertwingly.net/blog/2026/09...

"As if", a new post covering Aaron's closing keynote, DHH's new rust port of campfire, performance, and maintainability. Yes, it is "AI slop", but I think the questions this piece poses are worth exploring. intertwingly.net/blog/2026/09...

intertwingly.netTwo JITs, Opposite Signs

19 Sept

TruffleRuby specializes the interpreter to the program at runtime; Roundhouse specializes Rails to the app ahead of time. I'm now, for the first time, starting to measure the impact of each separately and together: intertwingly.net/blog/2026/09...

intertwingly.netCampfire, Buffered

9 Sept

Two days ago the compiled Campfire was 55% faster than Rails. Today it's 4x. One process against their eight. The change: a nested view appends into the caller's buffer instead of returning a string — 61% less allocation per request. intertwingly.net/blog/2026/09...

> My goal with JRuby has always been to give Rubyists more tools and more opportunities. By combining JRuby with the power and ecosystem of the JVM, we’ve brought Ruby and Rails to places it never could have gone before. Hold my beer. :-)

JRuby returns to RubyConf for the 2026 edition in Las Vegas! I will deliver a talk on Tuesday, run a Hack Space on Wednesday, and would love to hang out with you at JRubyKaraoke (Tuesday night) and the poolside JRuby Cabana (Thursday). Here's all the info: blog.headius.com/2026/07/jrub...
