To this day, very few web apps provide any undo/redo capabilities. This is really not such a good thing for usability. There are a few exceptions like gmail, but it does not go far enough to provide what every one is used on their desktop.
It is easy enough to debug specs on by one. For this you just run the ruby file that contains the spec with ruby-debug instead of ruby:
After releasing the first version of git-rails, Ron Damen created a clone of the repository and started improving on it. And I liked what he was doing, so now was the time to figure out how to get some of his changes back in to the master repo.
RUR (Rails-Undo-Redo) is a rails plugin (and soon a gem as well) to make it so easy to implement multi-level undo redo in your Rails application that you better start thinking of better excuses not to implement Undo/Redo (no, seriously, it is going to be a lot easier).
Git is quickly becoming one of the best option for using a DVCS (Distributed Version Control System). Git main goal is to be quick (most everything you do is local), and has already been battle tested by the Linux Kernel dev team.
I use ruby-debug quite a bit (too much? perhaps). And every time I start it, I find myself setting a few options (always the same ones), and it finally got to the point where I thought there had to be a better way. And there was! (Thank you, Kent)
I had been hearing about Gentoo for a long time, and finally discovered it in depth about 6 months ago. Gentoo is really a different beast as Linuxes go. You get to build everything from sources. No binaries. That’s right. That means that you get to build everything with compatible flags, get to remove a lot of the unnecessary bloat (Do I hear X windows for example?). It also means that the initial setup could take you several days if your machine is not so powerful. Suffice it to say, I really, really like the approach and that is now what I’m using to run this blog.
What started as a 5 minutes hack a few weeks ago is now a reality. I’ve put together a new gallery, and unlike many other galleries, you get to see all the existing themes for Mephisto as they would appear in a real Mephisto installation, because that’s where they all run. All sites show the same content, which makes it really easy to find out how each one treats sections, static pages, comments, sidebars, etc.
It started innocently enough. I was writing a Rails Plugin, and needed to call a Class Method on a Model. No problemo, right? In init.rb just call the method (To register a renderer in this case).
