Getting IronRuby Up and Running
I wanted to have a little walk-through on getting IronRuby up and running. I am normally a C# guy and this is usually a C# blog, but I think that exposure to dynamic languages is very important. Since .net is starting to get a bit dynamic (with IronPython, Boo (kinda), IronPython, and VB.net 10 (kinda)), I think that developers are going to start seeing this stuff more and more. Because of this I have created this little walk-through, but this month if you are in the Richmond VA area we are going to have our Meet and Code dinner (on the 31st of July 2008) on dynamic languages.Tracks screencast: How to get things done
This great application helps you to get more organized (Something I definitely needed!). Another good thing about it is that it requires a minimum of knowledge to be installed using the BitNami installer.Ruby's Open Classes - Or: How Not To Patch Like A Monkey
Ruby's Open Classes are powerful - but can easily be misused. This article looks at how to minimize the risk of opening classes, alternatives, and how other languages provide similar capabilities.Writing a compiler in Ruby bottom up - step 10
ach step so far has included minor bits and pieces to test specific features. But it's hard to get an idea for how complete a language is becoming without writing something a little bit more substantial. In this case I've chosen to write a "text-mangler" that will "parse" an s-expression like (Lisp like) syntax and turn it into a Ruby script that will run the compiler with the equivalent program.6 Optimization Tips for Ruby MRI
MRI is slow, we all know it, but knowing the internals can help you optimize.Adding Google Maps To Your Rails Applications
Although there's nothing preventing you from linking to Google's mapping JavaScript API and referencing the library directly from your views, jumping between Ruby/Rails syntax and JavaScript can quickly become a tedious affair. The YM4R/GM plugin remedies this issue nicely, abstracting the API calls through Ruby's familiar object-oriented syntax. With it you can do everything from render simple maps to build complex maps complete with custom markers, information windows, and clusters for facilitating the rendering of large numbers of markers.MVC: How to write controllers

After reading Ben Smith’s classic iPhone on Rails 2 article and implementing our own iPhone site after the jump to Rails 2, I was struck at how easy it is to create you own custom mime types to serve up different content to different devices.
When the time came to redesign the main MindBites site, I didn’t look forward to a lot of branching and merging, no matter how easy Git makes it. Then it hit me. Why not create a custom mime type and serve up a new layout and views for beta users? Let’s take a look at how we’re doing just that.Cheap Tricks XV - Static Collections in Java
Here's another cheap trick around reducing the common need for a static block populated listUsing jQuery with Ruby on Rails
By default, Rails comes packed with the Prototype javascript library and the effects library, Scriptaculous. While this is all well and good sometimes you want a change. I personally prefer jQuery to prototype. I don’t have any beef with prototype, infact I used it for about a year before even getting into rails, but I just prefer the jQuery syntax and selectors.Splunk your distributed logs in EC2

Rubyforge is now hosting an “initial pre-release of a preview of an alpha of an undocumented proof-of-concept” of the rewrite gem. Rewrite restricts things like andand or try to your code and your code alone. Sure, if you introduce a bug in your code, you may break things that directly depend on your code. But if you introduce “try” using rewrite instead of modifying Object, you will not reach out across your project and break something entirely unrelated that happens to have defined its own version of try in a completely different way.Settng Up The Templates for Ruby on Rails
A template can be defined as 'A master page that dictates the look and feel of the whole website.' In other words, a template contains information about the layout as well as placeholders for dynamic data, such as navigation, and menu. The definition provides us with the points on which we will be working, layout and navigation.How Ruby on Rails and REST go together
Rails 2.0, the latest version of the framework for the Ruby language, is made for doing REST applications, says Mike Clark, author of the newly released "Advanced Rails Recipes: 84 New Ways to Build Stunning Rails Apps".Cache it all
I recently redid my personal web site, at welton.it. Wanting to be quick about it, and make the look and feel a bit more uniform than it has been in the past, I hacked together some pages in Rails. Despite this being sort of a "killing a fly with a bazooka" situation, I've been doing lots with Rails, so it was quick to use. Here's the thing, though: Rails is definitely overkill, as the site is basically static. I don't need to calculate anything or fetch stuff from a database - I just wanted a reasonably good template system, and I am quite comfortable with Rails these days.Tutorial for installing and setting up LiteSpeed and a Rails App
Start to finish process of installing the LiteSpeed webserver for a Rails application.Fuzed and EC2: Scale Rails big and fast!
First of all, this post is about 2 things that rock. One is Fuzed, the new Erlang web glue that runs Rails on the Erlang-based Yaws web server, put together by Tom Preston Warner and Dave Fayram of Powerset. The other is Amazon EC2, which is a big, sneakily expensive nerd playland. I became interested in Fuzed at the talk I heard on it at RailsConf by Tom and Dave.Fractal Programming or Layers of Code
This is a continuation of my previous posts describing layers of code written in different programming languages. I have thought about the things involved for a while, and had several discussions with people about it. There were some parts that I didn't describe as well as I thought in my posts, and I will try to do better in this one.HUGE file upload with Ruby On Rails and Adobe FLEX
I spent 10 years now in web-based development and I never came across anything worse than trying to post big files to a web server.. Not only the problem of not being able to finish the upload because you kill the server but also the horrible wait for the operation to finish without any clue about the real status.. but now I have the final and robust solution for this task (with a cute and precise progress bar)!!
This example is obviously realized with RoR, but probably it’s not too hard to implement with PHP.Small Things, Loosely Joined, Written Fast
Thanks to everyone who came out to my talk yesterday at RailsConf. That has to have been my favorite speaking engagement of the last year. Great crowd at a great show.Setting up a Rails 2.0 Project without a Database
I needed to create a Rails application that wasn't going to use a database backend. In my case I was going to be using REST services to access the data, so I had no need for database integration.A Useful Example in Java, Ruby, and Groovy
We've been using Java and Ruby for work, and we've recently been asked to look more toward Groovy where we were using Groovy, so I rewrote a useful little iconv script which we use to re-encode large volumes of data (which the GNU iconv doesn't seem to want to handle).Connecting to MySQL using SSL encryption in Ruby on Rails

Sixth in my series on writing a compiler in Ruby: "How about some deferred evaluation and anonymous functions?
Lambdas, or anonymous functions, can be passed around like values and called at your convenience (or not at all). Generally, they can access variables from the surrounding scope that gets "bound" to the function as an environment that allows it to pass state. That's a closure. What we're going to do this time is not going to bring full closure support, but it's the start, and we'll get to full closures down the road."Fabio Akita advises a young Ruby beginner
