Jimbo Wales, founder of Wikipedia, will be speaking tonight at 8 P.M. on C-SPAN. The topic is the “Future of the Internet“, and one of the more interesting things that will be discussed is Wikia’s new wiki-based search engine being worked on.

With my recent involvement in trying to promote BarCampOrlando, seeing this kind of content on T.V. and especially in politics is a very pleasant surprise. I came across this flipping through channels and landing on C-SPAN right as the text blurb about Jimbo flashed by. They were talking about the Baghdad Embassy Contruction and mentioned a word that sounded very close to BarCamp… so I was REALLY excited for a second there =p I also recently sent out a personal email to Jimbo asking him for any involvement whatsoever in BarCampOrlando, since he lives in St. Pete, Florida and was quoted in the local Orlando Sentinel complaining about the lack of BarCamps and unconferences in the area.

I’ve recently been doing some very fun, elegant, and exciting things with Ruby at work and in my personal time. Although I have to admit that I learned Ruby because of the amount of hype Rails got on Digg back in the day, I am proud and overjoyed to consider myself a Ruby developer now.

Even though these bits of knowledge are obvious to advanced Ruby developers, I think there is value in recognizing these in context and expanding upon them. Below is my version of a summary of a presentation, courtesy Glenn Vanderburg.

• Punctuation gets in the way for short lines, but makes long lines more readable (this applies to the use of single versus multi-line blocks too.)
• The minimal syntax to open and close blocks makes their use feel natural. This naturalness is powerful, because blocks seem to allow powerful abstractions to be developed without much thought.
• Sigils are used for scope (@@, @, CAPS, $, etc) rather than typing (like in Perl.) This use of sigils helps, because the most common scopes (classes and local variables) do not have them. However, they provide an effective language feature that eliminates an annoying standard like using an underscore before instance variables (Java.)
• There are usually two (or possibly more) ways of doing something, allowing for the coded implementation to fit the context.
• Mixins/modules cannot create instance variables (because they cannot be instantiated), but they can reference them (because the instance variables spring into life inside of the object the module is mixed into.)
• The Enumerable module, along with blocks, allows Ruby to apply some functional programming techniques.
• Operator overloading.
• “Three-quals” (===) allows for beautiful case statements by defining the concept of a match.
• “Open classes” allow for nice common interfaces and DSL’s to be defined when patterns are discovered (ie: Rails’ blank? method on NilClass and String.)
• Classes being defined can execute code on themselves to define themselves further because they are objects.
• Although classes are just object instances, creating them still uses a declaration (unlike Smalltalk) and feels natural.

As a closing note, Ruby makes trade-offs in its design like any other language. These range from dynamic typing (which makes tool creation harder), to the “Principle of Least Surprise” (which make consistency harder), to many other things.

Glenn points out, and I agree, that Ruby seems to strike all the right balances (big ups to Matz.) However, this is a personal preference and we should respect the languages choices of others as a matter of taste… there’s room for everyone =)

BarCampOrlando is an opportunity for the Central Florida tech crowd to finally come together.

At BarCamp people from diverse groups, comprising of developers, designers, bloggers, and people that just plain love the web, can get together to share information, talk, and have a good time. It’s events like this that spur discussion to shape the future of the net, which makes BarCamp one of the most exciting conferences to attend. Best of all, it’s free and open discussion is encouraged, if not required!

My first BarCamp was in Jacksonville, and that’s where realized how serious blogging is thanks to presentations by Josh Hallet and Joey Marchy. I want to reiterate that this is just as much about ideas and discussion than presentations on specific technologies.

We have tons of great local user groups here in Orlando, for Ruby, Java, .NET, PHP, Adobe, Linux, Ubuntu, Creatives, and probably some things I’m forgetting. Additionally, the similar Refresh06 conference was a blast. I think we have an extraordinary opportunity to create an amazing event, so show your support by blogging about it and putting badges on your sites! Without blogging and your help, events like this don’t happen.

I’ll end this with a video explaining BarCamp and its history… see you there!
