@molecule Fair question. Tokaido ended up taking far longer than I expected (a big, huge mea culpa for sure). TL;DR: At long last, I plan to ship Tokaido, along with a website, documentation and automation at RailsConf this year. That wouldn't be the first time I said such a thing, but the feature set is actually done (and working on many test machines).

I dedicated a bunch of medium-time months at the beginning of the project to getting the initial set of functionality done:

* Figuring out how to statically build Ruby, which has required non-trivial updates with every version of Ruby, and a bunch of work to get some of those fixes upstream. Many of the projects that bundle Sass or Compass in a pretty GUI are making use of this initial work.

* Building a number of OSS libraries (https://github.com/tokaido) that enabled an application-isolated workflow like Pow with many fewer failure modes.

* Integration with popular tools that people use in development (redis-server and Postgres.app)

This process took longer than I expected (a year, rather than more like six months), and at the end of it, I had run out of work-time time to devote to the project. I turned my attention to nurturing a small community of people who could make Tokaido an open-source project that could be community maintained once we ship.

Andrés Robalino, in particular, helped me squash a number of important bugs that I was having trouble with (including a bug that was triggering occasional 100% CPU usage on some machines), and has cleaned up the process of building static Ruby and added a bunch of polish to the UI.

Tokaido has definitely not been my finest, quickest open-source turnaround, and it's fair for people who don't like me to use it as an example of my failures. That said, I think people who follow me know that I have committed my heart and soul to many more projects than Tokaido, many of which have large communities of people who love them.

Not everybody needs to love my projects or my style. I should have shipped Tokaido earlier, and for that I am sorry. That said, I am committed to finishing the job with Tokaido, and believe that the other major projects I have worked on speak for themselves.

Thanks for the reply and thorough update, that sounds awesome, and, especially: thanks for Bundler-- it makes so many developers' lives much easier!

Bundler, Merb, Rails 3, Handlebars, Ember and now Cargo?
