ObjectiveResource is an Objective-C port of Ruby on Rails' ActiveResource. It provides a way to serialize objects to and from Rails' standard RESTful web-services (via XML or JSON) and handles much of the complexity involved with invoking web-services of any language from the iPhone.

ObjectiveResource is a framework for the iPhone that makes interacting with Ruby on Rails applications dead simple.

Sometimes you want a single object to behave differently depending on what state it’s in. For instance, a traffic light has a different color depending on whether it is informing people that they should stop, slow down, or proceed. Or a user account object might behave differently depending on whether the account is in the “confirmed” state. AlterEgo can help you set up these state-based object “personalities”. AlterEgo will help you to define a set of valid states for your objects, and to define the allowable transitions between states. The real strength of AlterEgo, however, is in defining separate behaviors for each state that the object is in. Underneath the covers, AlterEgo will arrange for your object to delegate to a different state object depending on what state it is in. You can either explicitly define these state objects as classes, or use a concise DSL provided by AlterEgo.

A state machine plugin which allows each state to have different methods and behaviours.

AlterEgo is a Ruby implementation of the State pattern as described by the Gang of Four. It differs from other Ruby state machine libraries in that it focuses on providing polymorphic behavior based on object state.

Ruby on Rails is a powerful web framework that helps creating web applications easier, faster & writing an organized code. There are lots of websites that use it including popular ones like Twitter, Basecamp, AboutUs & many more. Also, Ruby on Rails powers some amazing open source web applications which you may want to use directly or improve further. Here is a well-categorized 23 open source Ruby on Rails applications

art up an instance of the 32-bit EC2onRails image:

"First of all, Amazon AWS rocks. it's a great, stable and not so expensive way to get your application up and running, but also ready for any disaster to come (Someone said Digg effect?). Getting your application on to Amazon EC2 is not as complicated as you think, managing and controlling your instances may require a professional system administrator, but i would recommend that anyway (except if you go and host your application on EngineYard than you are worry-free, but you'll pay.. ohh you'll pay for that sense of security)."

We were all teased a few months ago about the possibility of finally solving the nested model/complex forms problem in Rails, but were then cruelly notified that it wasn’t quite ready for prime time. But our day has come – the most requested feature for Rails 2.3, the ability to handle multiple models in a single form, is here.

Rails Performance Resources - Expert advice on tuning and optimizing your Rails app.

Long story short, Rails can now serve multiple requests in more than one ruby threads ( or native threads if you’re on JRuby ) parallelly. Charles Nutter has done a good job of explaining the details here. Should you give a flying fuck ? You totally should if : * You’re using JRuby * You’re bold enough to play around with bleeding edge Neverblock stuff * Your application has a lot of long running processes, which are not heavy on blocking IO ( this would be rare I imagine ) You totally should NOT if : * You’re using Event based mongrel, thin or any of the event based web server in production. Event based servers don’t use Threads, so it just doesn’t matter. * You CBA You may have heard a bunch of hype about how threads make everything 100x faster, this is far from the truth. Don’t believe everything the hype merchants want to sell you, test your application first and see if it helps.

A pro-caching technique for presenting cachable relative times (e.g., "15 minutes ago")

I put together a new mini app for our new status site yesterday that needed exactly this technique. I wanted the content of the application to be entirely page cached, so it would withstand the onslaught if the terrible should happen and we need to redirect all trafic to the status site.

provides a really easy way to write tasks that must be done repeatedly or at a certain time in a simple Ruby DSL. It can even write out crontab files for you based on the commands and times that you give it.

The line between Content Management Systems and Application Frameworks is starting to blur and this is the core basis for this post. The comments are also great reading and provide a balanced argument for CMSs

Sunlight Labs Blog says that CMS's don't work because they contain too many 'opinions' that you won't agree with (to do with user interface and workflow) so you are better off using content frameworks.

Trek Rails Forms microformat This article has been updated to reflect the latest patterns in Rails 2.3 edge (based mostly on this commit) If you’ve been relying on Rails form helpers to generate forms, then you may have missed the interesting little microformat used to pass application data to and fro. In case you didn’t know, form data is passed as part of the request body as a set of key/values pairs in plain text (if you’re using get as a method for a form, it’s that url section like this: ?name=widget12&price=22). The name attribute of the form inputs are the keys (here name and price), and the value is whatever the user entered or selected (widget12 and 22). Most languages/frameworks for the web will reconstitute these pairs as objects accessible to the programmer. For example <input name='widget_name' /> is accessed with $_POST["widget_name"] in php, self.request.get("widget_name") on App Engine, and params[:widget_name] in Rails. This format can only pass a single value f

g system, mobile platform, or web platform. Basically, if you want to share a short thought, one to many, Twitter is a transport-independent way to do that. In a broader technical sense, we see ourselves as a short messaging layer for the internet. We’ve been described as a “telegraph for web 2.0.” One of the things that’s core to our business is providing open APIs for everything you can do on the website. So all the functionality that’s available there for users is also available for developers to access programmatically. That’s Twitter in a nutshell. Twitter started as a hack project at a company called ODEO, which was focused on podcasting. As ODEO was having some troubles in its latter days as a company, they started experimenting, to keep engineers involved by letting them play around with ideas they had on the side. One of the engineers, Jack Dorsey, had been really interested in status. He was looking at his AIM buddy list, and seeing that all of these guys were saying, “I’m w

Nice article from Dr Nic on testing outbound email using cucumber and email-spec. I've tried it and it works like a treat.

Plugin that monitors the fields you're actually using from queries you make and over time dynamically adjusts your queries to retrieve only the fields you need. Apparently includes some magic to go re-query for more fields if you attempt to use one you hadn't loaded in the trimmed query. Amazing-looking stuff, though since we're currently using a DB on the same machine, transferring lots of extra data isn't nearly as expensive.

Dynamic query optimization is a hotbed of research in the database industry. Each and every query you execute goes through a rigorous optimization phase which tries to squeeze every last bit of performance: deciding which indexes to use, the execution order and sort order to minimize the number in-memory tables, etc. However, one thing the database has no access to is the application layer knowledge of which data the user is actually using after it is retrieved. Often times, the query fetches all of the columns when only a few are required, which is exactly the pattern that Lourens Naudé is seeking to optimize with his new plugin: scrooge.

I've been reading a bunch of papers about distributed systems recently, in order to help systematize for myself the thing that we built over the last year. Many of them were originally passed to me by Toby DiPasquale. Here is an annotated list so everyone can benefit. It helps if you have some algorithms literacy, or have built a system at scale, but don't let that stop you.

Including transparent sending of production traffic to staging.

Lift the curtain behind any modern web application and you will find at least a few proxy servers orchestrating the show. Caching proxies such as Varnish and Squid help us take the load of our application servers; reverse proxies such as Haproxy and Nginx help us partition and distribute the workload to multiple workers, all without revealing the underlying architecture to the user. In the Ruby world, Rack middleware and Rails Metal are sister concepts: both allow the programmer to inject functionality in the pre or post-processing step of the HTTP request.

The best part about Webhooks is that most of us are already familiar with them: callbacks over HTTP. Pioneered by PayPal and Subversion as a way to send real-time notifications to the client, they have found their way into many dozens of products we all use every day. Need pre or post commit hooks for your SVN or Git repository? Both GitHub and SVN support HTTP callbacks. Need a payment alert from PayPal, or an alert when a wiki page is modified? There are webhooks for that too. This simple mechanism allows us to build web services that work together via a simple and ubiquitous protocol we can all understand: HTTP!

“We don’t have 200k RSS subscribers because of my deliciously swirly hair” - a central question (asked also during the Q/A session): how on the earth did Basecamp and other 37signals products become so popular? All of a sudden, they emerged from nowhere! As David points out, it was not that ‘out of the blue’ as it looks like. When they started with Basecamp, they already had 2000 subscribers on their blog, Signal vs Noise, so they built a channel which through they could advertise themselves. This advice meshes with one of my favorite points from Getting Real which goes something like “Just start doing something”. Really. Start blogging. Creating/contributing to open source software.

Cet article explique ce qu'est AMQP et comment l'utiliser en Ruby.

The flexibility of the message and the exchange model is what makes AMQP such a powerful tool. Whenever a publisher generates a message, he can mark it as 'persistent' which will guarantee delivery through the broker - if there is an attached queue, it will accumulate messages until the consumer requests them. However, if you're streaming transient data (access logs, for example), you can also disable message persistence and not worry about overwhelming your broker. That's how you achieve 'exactly-once' vs 'at least once' semantics.

collection of rack middleware

If you've worked with Web apps using Ruby, you might know of Rack, an interface that sits between Ruby applications and HTTP-speaking Web servers. All of the major Ruby frameworks and server setups use it now, including Rails. Middleware (in Rack) is code that manipulates data going back and forth between your Ruby apps and the HTTP server. You can use middleware to intercept requests, change data in mid-flow, etc. Ryan Bates has a great screencast tutorial if you're new to the concept and want to build your own.

Even though the gradual engagement meme has been around for a while, and everyone just hates signup forms, they just seem to keep popping up like a bad habit. My site, Newsforwhatyoudo.com was one of the guilty parties. We saw users coming back to the site repeatedly, but not signing up. The percentage that looked at the signup form and then bolted was uncomfortably high. It was time to kill the signup form. This blog post documents how we implemented gradual engagement using Ruby on Rails and restful authentication.

Really interesting article about mongoDB and about the installation procedure

"MongoDB can be thought of as the goodness that erupts when a traditional key-value store collides with a relational database management system, mixing their essences into something that’s not quite either, but rather something novel and fascinating. -- MongoDB support is available in many languages, making it a good choice for a system that has to work in a polyglot environment; all of the major languages have support."

use RSpec in all my projects. It’s really hard to overemphasize how helpful it is and how much easier becomes your life if you have good specs coverage. But its outstanding flexibility enables many ways to make your specs awful: horribly slow, over-bloated, even non-readable sometimes. I do not want to teach you BDD and RSpec here, but instead I will give you some ideas how to improve your specs quality and increase efficiency of your BDD workflow.

I have a different vision - one that sticks it to the suits so hard it will make their eyes water. How about a community where women are valued for their ability to program and not by the thickness of their skin? How about a community that edgily pushes new boundaries without reinforcing long running evils? Perhaps even a community where women reach equal numbers? Such a community would hand the suits the defeat in the long battle women have been fighting for centuries. I'd love to be part of that.

A couple of weeks ago there was a Ruby conference in San Francisco called GoGaRuCo (Golden Gate Ruby Conference). This conference has grabbed attention due to a talk at which the presenter illustrated a discussion of CouchDB by using sexually suggestive pictures of women. Unsurprisingly the result has been a fair bit of heated, and occasionally offensive, debate.

David Heineimeier Hansson, the creator of Ruby on Rails and partner at 37signals in Chicago, says that planning is guessing, and for a start-up, the focus must be on today and not on tomorrow. He argues that constraints--fiscal, temporal, or otherwise--drive innovation and effective problem-solving. The most important thing, Hansson believes, is to make a dent in the universe with your company.

I've been a big proponent of NoSQL for a while. I have played with just about all of the new generation of data stores. We almost got cassandra running in production once, and we've been running mongodb in production for about six months now. But, here's the thing: as awesome as these new dbs are, they're still young. Our app generates a ton of data and gets pretty serious traffic. So, we started hitting walls quickly. To make a long story short, we decided to fall back to MySQL. It's battle hardened. We know its production characteristics and limitations. Backups are a science. We know we can count on it. But, we have a lot of data, and adding fields and indexes was starting to get painful. Flexible schemas are one of the things that attracted me to NoSQL in the first place. Then, I remembered this article about How FriendFeed uses MySQL to store schema-less data. So, I decided to implement the system they describe in the article. Since we put Friendly in to production, we've seen

Friendly makes MySQL look like a document store. When you save an object, it seralizes all of its attributes to JSON and stores them in a single field. To query your data, Friendly creates and maintains indexes in separate tables. It even has write-through and read-through caching built right in.

Rails 3.0 is a landmark release as it delivers on the Merb/Rails merge promise made in December 2008. Rails 3.0 provides major upgrades to all of the components of Rails, including a complete overhaul of the router and query APIs.

These big picture changes have concentrated on a few key areas: * Decoupling Rails components from one another as much as possible, making things more modular and a la carte. * Pulling in improvements from Merb and rewrite/refactor much of the internals to improve performance. * Exposing explicit, documented API’s for common tasks and integration of wider ecosystem components from testing, ORM, etc.

I guess the conclusion is that there’s no use in preempting the technological progress of tomorrow. Machines will get faster and cheaper all the time, but you’ll still only have the same limited programming resources that you had yesterday. If you can spend them on adding stuff that users care about instead of prematurely optimizing for the future, you stand a better chance of being in business when that tomorrow finally rolls around.

The very things I find ugly in Ruby are what make amazing Ruby software like RSpec possible, and that Python could never have (given the current implementation). Gary Bernhardt I think Ruby's syntax is ugly until they do something glorious and beautiful with it like Rake, then I think "damn it!" Unidentified Attendee

That minimalist approach encompasses more that just aesthetics. It also informs our technical decisions, architecture, and the tools we use.

A good story about PHP and Ruby. I think a lot of developers get stuck up in their religious code circles that they forget that what they're really doing is mundane and completely stupid. Bottom line, be a lazy programmer.

Striking a balance between custom code (Rails) and off-the-shelf software (CMS)

"Ruby on Rails is an excellent framework for building web applications. Perhaps the best. But it's not currently very well suited to what I call web sites. The difference is simple. In a web site, the unique business value comes from the content creators (authors, bloggers, photographers, etc). In a web application, the business value comes directly from the programmers. Twitter, Google, Basecamp and eBay are web applications. CBSSports.com, KentuckyDerby.com, corporate brand sites and original news sources are all web sites."

using Jeremy McAnally's rails generator or the template feature that made it into rails core

template is able to generate a clean rails app which is basically bort (Or exactly bort. Or very similar to bort. Or similar to a bort lookalike. Or… I guess I leave this debate up to ruby lawyers, bort experts, rg zealots etc.) Anyway, it doesn’t really matter as rg was not invented to compete with bort - bort is merely used as an example because it’s probably the most popular Rails skeleton app nowadays - rg is far more general than that: an easy, concise, Rubyish way to describe your Rails app (including plugins, vendored gems, lib files, initializers and whatnot) in a very straightforward way.

During the last year I've ported a number of gems and Rails apps to Ruby 1.9. I feel it's important we as a community get the transition from 1.8 done and over with as soon as possible so we can get back to doing real work.

Maybe you're even one of those performance trolls, childishly happy reading articles like The Great Ruby Shootout and then goes back to coding in yesterdays Ruby like it's '99. ;)

You'll learn, over the course of this article, more than a few tricks that will help your website stand out on the iPhone. Knowledge of Ruby is not required to learn from this article as it relies heavily on Cascading Style Sheets and JavaScript to work its magic. You should be able to apply the tricks you'll learn here anywhere you'd use JavaScript or CSS. This article will not teach you everything you need to know about web development with Ruby on Rails, it will simply point out where the iPhone's browser differs from an ordinary one.

Migrations bother me. On one hand, migrations are the best solution we have for the problem of versioning databases.

Check the brainstorming at the end. I love where he's going. Short version: a schema.yml file identified by its SHA1 hash. Migrations are for translating data between versions. Great comments at the end by the smart people in the community.

Rails 2.3 gives us “default_scope” which was described by Ryan Daigle as allowing you to “specify default ordering, and other scopes, in edge rails directly in your ActiveRecord model.” Ryan’s post gives some good examples of when you might want to use this (specifically on models where you always want them sorted in a specific manner). In the comments of that post, Ryan Bates suggests that this might be useful for “simulating destroying a model (like acts_as_paranoid).” Indeed this is possible and the idea of using scoping to create this is both present in acts_as_paranoid itself and also has been brought up before. In this article I’m going to reinvent the wheel using default_scope to illustrate how powerful default_scope is and how trivial it makes this task. You can keep track of the finished product in my is_paranoid gem.

Using Amazon EC2 Metadata as a Simple DNS

I use the amazon metadata for creating /etc/hosts and do this on a cron schedule. This does everything I need. Instead of fancy DynDNS tricks or having to run and manage an internal DNS server I just have a ruby script that looks at the metadata ec2 to build /etc/hosts. It's easy. To set it up yourself and try it all you need are 3 easy steps. Step 1- Start each of your instances with unique named key that matches what you want their internal hostname to be. Such as "onion" or "potato" or whatever you want to call them. Step 2- Make sure you have ruby, rubygems and amazon-ec2 (rubygem) installed. Then create a ruby script in /usr/local/sbin/hosts that has the following:

"I use the amazon metadata for creating /etc/hosts and do this on a cron schedule. This does everything I need. Instead of fancy DynDNS tricks or having to run and manage an internal DNS server I just have a ruby script that looks at the metadata ec2 to build /etc/hosts."
