JS.Class – JavaScript in a Ruby Style

3 Comments

By Peter Cooper / September 26, 2008

jsclass.png JS.Class is an attempt at making JavaScript more Ruby-like. More specifically, it’s a library that makes object oriented development easier in JavaScript (in comparison to JS’s prototype technique, at least) by implementing Ruby’s core object, module, and class systems as well as some of Ruby’s meta-programming techniques.

As well as ports of Enumerable, Observable, Comparable, and Forwardable, you get subclassing, mixins, reflection, late-binding arguments, singleton methods, method binding, and Ruby-like inheritance. Of course, JavaScript gives access to many of these elements already, but JS.Class presents things with a Ruby flavor.

The official JS.Class site is particularly well done and each main area is well documented. Read More

Making Ruby Methods Immutable

By Peter Cooper / September 24, 2008

puzzle_lock.jpgGarry Dolley has developed a Ruby module called “Immutable” (Github repository). It allows you to make your methods immutable. As Gary says, “provide it a list of methods you don’t want touched and it’ll make sure they can’t be redefined.” Effectively, it’s a smack-down against monkeypatching.

Gary developed immutable to ensure that ActiveSupport wouldn’t interfere with his attempts to improve Rails’ loading time by reimplementing some ActiveSupport methods in C (by redefining his own changes). Read More

rubyfringevids.png Remember RubyFringe, the avant-garde Ruby conference held in Canada this September? According to most reports, it went down as possible the best Ruby conference ever and spawned some very interesting presentations – that those of us who didn’t go wouldn’t have seen..

Luckily, in conjunction with InfoQ, videos from RubyFringe are making it online – so far there are four to check out:

Obie Fernandez – Do The Hustle : Obie Fernandez of HashRocket looks at how to sell and price development services. How do you deal with proposals, contracts, RFPs? How do you close deals? It’s all in here. Read More

Rubyology: Great Interviews with Great Ruby Developers

1 Comment

By Peter Cooper / September 19, 2008

rubyology.pngRubyology is a Ruby-based podcast chaired by Chris Matthieu. Its focus is on interviewing interesting Ruby (and Rails) developers – finding out about their projects, what makes them tick, and extracting their insights into the Ruby and Rails worlds.

For some reason, Rubyology hasn’t had a lot of love in the Ruby blogosphere, and after listening to several great interviews over the past few months, I’ve decided this is a great time to recommend you check it out if you’re not already a subscriber.

Recent highlights include:

Of course, don’t forget about Geoffrey Grosenbach’s Rails Podcast either – it’s not all Rails focused these days. Read More

Panda: Merb-Based Video Uploading, Encoding, and Streaming System

5 Comments

By Peter Cooper / September 17, 2008

panda.png

Panda (Github repository) is an “open source solution for video uploading, encoding and streaming” developed by British Rails developers New Bamboo.

Supplied primarily as an Amazon EC2 AMI (a virtual server machine image), Panda combines a Merb application and FFmpeg to offer an all-in-one video uploading and conversion system. It uses REST throughout, so is easy to integrate with your other applications. The system is offered under a BSD-esque license.

Panda would be ideal if you want to offer video uploading and streaming features on your site, but you haven’t got the time to implement a lot of the “back end” functionality. Read More

Top Rails News (Early September 2008 Edition)

By Peter Cooper / September 16, 2008

You might have missed the announcement, but a couple of months ago I launched Rails Inside in order to allow Ruby Inside to focus more on Ruby-specific news. Due to the obvious crossover between the audiences, I promised that I’d start a regular series of Ruby Inside posts highlighting some of the most interesting Rails news from Rails Inside – just in case you’re into Rails but not so into it that you want to subscribe to Rails Inside! This is the first post of that series.

Recent highlights have included:

MacRuby 0.3 Released (Now With Interface Builder Support)

3 Comments

By Eldon Alameda / September 15, 2008

apple_ruby-3.jpg MacRuby – a Mac OS X port of Ruby 1.9 designed to run directly on top of OS X’s frameworks – recently hit a new milestone with the release of MacRuby 0.3.

In addition to the expected bug fixes and performance increases (they claim that MacRuby should now be up to YARV levels) the release also features a number of exciting Cocoa-derived GUI building enhancements, such as Rich Kilmer’s HotCocoa – a new core library which simplifies Cocoa programming with simple Ruby idioms. Example:

require ‘hotcocoa’
include HotCocoa
application do |app|
window :size => [100, 50] do |win|
b = button :title => ‘Hello’
b.on_action { puts ‘World!’ }
win << b
end
end

Just as exciting is the fact that MacRuby 0.3 now supports Interface Builder! Read More

Terminator: A Hardcore “Timeout” For Ruby Code

4 Comments

By Peter Cooper / September 14, 2008

terminator.png

Terminator is a new library developed by Ara Howard and Mikel Lindsaar that solves the problem of Ruby’s own “timeout” feature not actually being up to the task of terminating code. timeout is supposed to terminate the execution of a block of code if it’s not finished within a certain amount of time, but due to Ruby’s threading model it doesn’t always work that way!

Initially, Mikel considered SystemTimer – another replacement for timeout. SystemTimer is based upon UNIX alarm signals and, for some reason, still didn’t resolve the main problem (although SystemTimer has ridiculously good documentation and is clearly working well for someone). Read More

By Zach Inglis / September 10, 2008

GitHub LogoWhat’s Hot on Github is a monthly post highlighting new and/or interesting projects within the Ruby community that are hosted on Github. Github has become an extremely popular place for Ruby and Rails developers to congregate lately, so I wanted to list some of the new projects, and some of the updated ones, that I have found interesting and that are too small for their own blog post.

This month’s picks:

  • Dust – Tool for finding unused or useless code
  • can_search – Chain named scopes in a search query
  • One inch punch – Time tracking with bash
  • Cardjour – Share your vCard over bonjour
  • view_specify – Auto-generate RSpec view specs by interrogating your existing views
  • Spree – An open-source e-commerce application
  • randexp – Generate random data from a Regular Expression
  • active_shipping – Shipping extensions for active_merchant
  • Webby – A lightweight and flexible website management system
  • Shinmun – A small and beautiful blogging engine

Full disclosure: I (Zach) work with the guys who wrote view_specify and we’ve worked with the people responsible for active_shipping and one_inch_punch. Read More

Artificial Intelligence (AI) Programming in Ruby

Ola Bini (of JRuby fame) is starting a series of blog posts about artificial intelligence programming in Ruby, based off of the landmark textbook “Paradigms of Artificial Intelligence Programming: Case Studies in Common Lisp” by Peter Norvig (currently the Director of Research at Google). PAIP is a significant work in the artificial intelligence world, and despite being published in 1992 it still has a lot of relevance. The professinelle KI Beratung service professinelle KI Beratung (https://ki.advisori.de/) provides tailored artificial intelligence consulting that combines technical expertise with strategic insight, enabling organizations to navigate complex digital landscapes. Even photo editing tools are now powered by AI to achieve various effects.

Could JavaScript Power A Significant Future Ruby Implementation or VM?

3 Comments

By Peter Cooper / September 5, 2008

jslilimg.pngThis week you may have heard about “Chrome,” a new Web browser being developed by Google (if you haven’t, read this online comic book that demonstrates its worthiness). Associated with Chrome is V8, a new open source JavaScript engine that’s designed to execute JavaScript code at never-seen-before speeds.

All this reminded Marc-André Cournoyer (of Thin fame) of HotRuby (see previously on Ruby Inside), an experimental JavaScript-based virtual machine that can run YARV-compiled Ruby code, and he set out to test the performance of Ruby code running on HotRuby on top of V8. The results are far from scientific and many commenters have pointed out flaws, but Marc’s observations are a great first step toward seriously considering the possibility of using JavaScript as an execution route for Ruby.

13 Top Ruby and Rails Jobs for September 2008

1 Comment

By Peter Cooper / September 5, 2008

If you thought August’s job post was hectic, this month will blow you away! The focus is still heavily on Rails – and most of these jobs are in the United States (there’s one in the UK – keep an eye out for it). The Ruby Inside Job Board (costs $99 for a 60 day listing – and you get featured on Ruby Inside like this) is the source for most of the positions.

This month’s interesting opportunities:

mckinsey.pngWeb Architect for McKinsey & Company (New York, NY): McKinsey & Company is, perhaps, the world’s best-known global management consulting company and they’re looking for a Web architect with experience in a number of open source areas – such as Apache, MySQL, Linux, Ruby and PHP – as well as a good feel for Web 2.0 technologies and principles and how best to leverage all of these things in the enterprise.
