Design Patterns in Ruby documents smart ways to resolve many problems that Ruby developers commonly encounter. Addison-Wesley Professional press has this exciting book, authored by Russ Olsen.

Russ Olsen has done a great job of selecting classic patterns and augmenting these with newer patterns that have special relevance for Ruby. Most design pattern books are based on C++ and Java. But Ruby is different—and the language’s unique qualities make design patterns easier to implement and use.

RM-Manage is a monitoring product for Rails applications. Their claim:

Building elegant and powerful Rails applications rapidly is important. Ensuring that they perform properly once deployed in production is even more important. A poorly performing or unavailable business-critical application can have a devastating impact on your bottom line, negating the benefits of Rails development.

Rails applications are more than just Rails itself. Databases like MySQL and Oracle, web servers such as Apache, and even the host operating system each affect performance and availability.

Practical Reporting with Ruby and Rails is a great book for Ruby and Rails developers seeking to create compelling business intelligence and reporting solutions using a wide variety of applications and services. Published by Apress, and the author is David Berube.

Business intelligence and real-time reporting mechanisms play a major role in any of today’s forward-looking business plans. With many of these solutions being moved to the Web, the popular Rails framework and its underlying Ruby language are playing a major role alongside web services in building the reporting solutions of tomorrow.

You know what, I really wanna learn this whole JavaEE-related thingy……

For some reason it’s unavoidable……. it’s bound to be touched by me……

You see, the trend is going RIA. MVC is going away. AJAX ain’t gonna compete. At least not fully. And will lose in many ways in respect to something like Adobe’s Flex. (Unfortunately there’s not much competitor better than Flex, and fortunately it’d probably be “standard” in the near future). Esp. with Flex going open source. Flex will need a backend, since it’s not a server-side product. There is Flex LiveCycle Data Services ES (what a name!!) by Adobe. There’s also BlazeDS open source. There’s also the excellent WebORB, which is free and open source for Rails and PHP. Oh yeah, it’s free for Rails!

Robert Thau from Smartleaf proposes a cool idea for implementing DSL for use in Active Record permissions. It makes it easy for a lot of users to have access rights and very exciting at the same time…

This is the Tease….

class Order < ActiveRecord::Base

  access_control_keys ['id', 'owner_id', 'paid']

  require_privilege :place,
    :for_action => :create,
    :to_update_attribute => [:payment_authenticator, :paid]

  require_privilege :edit,      # LineItem also checks this for attr changes
    :to_associate_as  => ['LineItem#order'],
    :to_dissociate_as => ['LineItem#order'],
    :to_update_attribute => [ :shipping_address ]

  require_privilege :ship,       :to_update_attribute => :shipped

  ...

end

 

The implementation:

• Data model

Just out is ActiveRecord-JDBC 0.6, the post-RubyConf release.

The sparkly new feature is Rails 2.0 support. In the soon-to-be-released Rails 2.0 (edge), Rails will automatically look for and load an adapter gem based on the name of the adapter you specify in database.yml.

let’s see the example:

development:

  adapter: funkdb

  ...

We can leverage this convention to make it easier than ever to get started using JRuby with your Rails application. So, the first thing new in the 0.6 release is the name. You now install activerecord-jdbc-adapter:

jruby -S gem install activerecord-jdbc-adapter

Any Ruby on Rails programmer would have touched Active Record, probably in a very early phase. Active Record deals with everything that’s related to the database of your Ruby on Rails applications, and in many ways a bit more.

Apress recently launched Pro Active Record: Databases with Ruby on Rails, which I can honestly say, is the most exhaustive, if not the only, book about Active Record I’ve ever known to date.

Just out from a pack of several of the world’s greatest Ruby and/on Rails programmers: Professional Ruby Collection: Mongrel, Rails Plugins, Rails Routing, Refactoring to REST, and Rubyisms.

Some people asked me about SVK so here it is. Quickly written because I am a bit lazy and sleepy right now.

SVK is a distributed version control system. In other words, it allows you to mirror a Subversion repository, have local commits, pull changes from upstream, and synchronize/merge it back to the remote Subversion server if you want.

English version

UPDATE: This is an outdated version. The most up-to-date version with newer tips and tricks is in wiki Ruby Indonesia: SVK, which unfortunately is only available in Indonesian.

Method 1: Use Subversion repository, but SVK working copy

Who said Capistrano is for Ruby on Rails only?

That’s probably the major tagline of the whole Capistrano 2.0 saga. You can use it to deploy PHP, Django, or not doing any deployment at all. Let me demonstrate, this time using Joomla:

Capistrano adalah library/tool yang digunakan untuk meng-online-kan aplikasi Ruby on Rails, tapi bisa juga digunakan untuk aplikasi PHP, misalnya Joomla:
