1 Comment

By Peter Cooper / November 2, 2007

As long time readers will know, Ruby Inside has its own jobs board at jobs.rubyinside.com. It doesn’t just have jobs posted only by Ruby Inside readers, but also jobs scraped from all over the Web with many Ruby and Rails related jobs being picked up every day (e.g. how does being a Ruby Engineer in Los Angeles take your fancy?).

Only two jobs were posted by Ruby Inside readers in October, but deserve special attention:

Thanks to an article called “Top Programming Books on Google Book Search“, I’ve discovered that many of the pages of my book, Beginning Ruby (available also in e-book format here), are available here on Google Book Search. Most of Chapter 3 is there, along with chunks of every other chapter, including quite a bit of Chapter 16, a reference of “Useful Ruby Libraries and Gems”.

While I have your attention and while I’m officially posting about the book, so far it has 9 reviews on Amazon, 8 at 5 star, and 1 at 4 star, and they are well worth a read if you’re wondering whether the book is for you or not. Read More

Leoparddisk20070611

Someone / some people who have been responsible for integrating Ruby and Rails into the latest version of Mac OS X (Leopard) have written some notes on what was involved and how Ruby and Rails work in Leopard. The Ruby build is a customized 1.8.6 p36 and actually integrates into Xcode and Interface Builder.. now making it a relatively easy task to put together Ruby GUI apps on OS X. RubyGems is also installed with a smattering of the most popular gems preinstalled by default. Read More

The interesting thing about PackR is that it comes as a Rails plugin to enable you to have the JavaScripts associated with your Rails apps “packed” on the fly. Read More

Mailtrap: Dummy Ruby SMTP server (ideal for testing ActionMailer)

7 Comments

By Peter Cooper / October 18, 2007

Trap

Mailtrap is a “dummy” SMTP server developed in Ruby by Matt Mower. The main use for Mailtrap is to act as an SMTP server that runs locally and can be sent mail which can be inspected for debugging purposes. For example, your Rails application running locally might need to send mail using ActionMailer, and while you want it to go through all of the SMTP motions, you don’t want the mail to really be sent.. enter Mailtrap! In this blog post, Matt goes into more details about how Mailtrap works, why it’s a good idea, and the motivation behind its development. Read More

More New Rails Screencasts from RailsCasts.com

1 Comment

By Peter Cooper / October 16, 2007

Ryan Bates is being a total champ in rolling out more and more consistently good Rails related screencasts for free at RailsCasts.com. Some of the latest include:

Adding an Environment – Rails comes with three environments: development, test, and production. But, you aren’t restricted to just these. You can add your own! See how in this episode.

Testing Controllers – Controllers are tricky to test, and there’s no perfect way to do it. In this episode you will see how I test controllers, and my reasoning behind it.

Custom Routes – In this episode you will learn how to add custom routes, make some parameters optional, and add requirements for other parameters. Read More

glTail: Sexy Log File Visualization using Ruby

3 Comments

By Peter Cooper / October 12, 2007

Gltail

glTail is a great little Ruby script by Erlend Simonsen (aka Fudgie) that uses OpenGL and Ruby to visualize the events taking place in log files in real time. An example video on the official site shows requests coming into an HTTP server, each represented by a “ball” which is thrown across the screen. The script uses net-ssh to connect to a server and then libopengl-ruby to output the graphics. Parsers are included for processing Apache, Rails, IIS and Postfix log files. Nice work! The code is merely a couple hundred lines of Ruby, so if you’ve fancied putting together a basic OpenGL app, it’s worth looking at it for that reason too. Read More

CplusRuby: Fast custom C structures within Ruby

By Peter Cooper / October 11, 2007

CplusRuby is a new library by Michael Neumann that makes it really easy (as in, even easier than RubyInline, although CplusRuby is of a smaller scope) to define custom C structures from within Ruby. The major goal of CplusRuby is performance, and the ability to easily define small methods within a class that compile to C and which can call each other directly. An example is always better than an explanation, so check out this code. Read More
