Reference

Whenever something's a really "big deal" in the Ruby world, we cover it - even if it makes more sense on Rails Inside (which is now switching to a user contributions model). Given that, we've gone through all the latest and greatest Rails 3.0 related links and put together a ton of them to help you on your way with the recently released Rails 3.0 beta. Enjoy!

Norwegian Rubyist August Lilleaas has been busy putting together a ton of examples of using the Net::HTTP Ruby library that comes with most Ruby distributions. I asked him if it'd be okay to put some of them directly on Ruby Inside for reference purposes and he said "No problem!"

Egyptian Ruby developer Muhammed Ali (of MySQLPlus fame) has released the first draft of a "Ruby 1.9.x Web Servers" booklet. It looks at how different HTTP daemons and server libraries (Thin, Passenger, WEBrick and Mongrel) perform in Ruby 1.9.1. You can read the book for free on his site or on Scribd, but if you want to download a PDF to view locally you'll need to have a free Scribd account, alas.

Learnivore is a new(ish) site by French Rubyist Thibaut Barrère that aims to aggregate all of the best screencasts in any easy to navigate, searchable manner. Learnivore is worth following (you can even follow it on Twitter) because unlike blog posts, screencasts from disparate sources haven't really been specifically indexed and presented well before.

New to Ruby 1.9 is the concept of fibers. Fibers are light-weight (green) threads with manual, cooperative scheduling, rather than the preemptive scheduling of Ruby 1.8's threads. Since Ruby 1.9's threads exist at the system level, fibers are, in a way, Ruby 1.9's answer to Ruby 1.8's green threads, but lacking the pre-emptive scheduling.

Whether you love it or not, as a Rubyist you probably have a copy of Programming Ruby (also known as The Pickaxe) floating about. It was the first English language Ruby book to be published and was instrumental in boosting Ruby's popularity in the early noughties.

If you've developed a Web application using Ruby lately, you've probably used Rack in one way or another. Rack calls itself a "Ruby Web server interface" and I tend to think of it as an abstraction between the messy world of HTTP and the potentially just as messy world of your code.

Vidar Hokstad is the writer behind the fine Writing a Compiler in Ruby series, but he's taken a break to explain the structure and semantics of the Ruby object model. It's a fine walkthrough.

It's approaching two weeks now since Ruby 1.9.1 was released, bringing with it not only a whole stack of extra performance and a new VM, but also a lot of compatibility issues. No pain, no gain!

Back in March, Ruby developer Gregory Brown raised the idea of receiving donations so he could work on open source Ruby projects full-time. It went well, and out of this project came Prawn, a pure Ruby PDF generation library. Not one to rest on his laurels, Gregory's now working on a book for O'Reilly called Ruby Best Practices, billed as "for programmers who want to use Ruby the way Rubyists do." The book will cover how to design "beautiful" APIs and DSLs, along with lots of other general topics that will make your code more expressive and make you a better Ruby developer into the bargain.

When Ruby Inside started over two years ago, there were only a handful of sources for Ruby related news. The announcements on the ruby-talk mailing list (which Ruby Weekly News - now deceased - rounded up on the Web), del.icio.us, and a few popular Rubyists blogs (such as Why's Redhanded). Now, however, there are lots of options, including Ruby Inside itself, Rails Inside, RubyFlow, Ruby Reddit, and Planet Ruby on Rails.

Last week, Noel Rappin of Pathfinder Development wrote Elements of Ruby Style - an attempt at producing a Ruby "style guide." After some initial feedback to this, he's followed up with a response to some of the initial criticisms and suggestions.

Ruby is an easy language to learn, but it's often necessary to look up something we've forgotten. A combination of Google plus any Ruby books we have on our shelves can help, but sometimes it's handy to refer to a simpler set of notes - such as a "cheat sheet." This post attempts to cover the most interesting ones.

AIR has gone Public Beta, so does anybody use it? eBay does, Adobe has more, and who doesn't love twitter?

Deplate is a Ruby-based tool written by Thomas Link to convert documents written in wiki-like markup to various output formats. Supported output formats include LaTeX, HTML, "HTML slides", DocBook (which means it can also convert to PDF, and other DocBook-supported output), and plain text.

"How To Think Like A Computer Scientist" is a range of online books (distributed under the GNU Free Documentation License) developed by various authors each focusing on a different programming language and explaining computer science concepts with it. Elizabeth Wiethoff has now started the Ruby edition and has made her work so far available online.

I keep getting e-mails about job sites, Ruby jobs, and so forth, so I decided it's time for a bumper "here are all the Ruby and Rails job sites" post! Enjoy..
