Chef is a systems integration framework, built to bring the benefits of configuration management to your entire infrastructure. With Chef, you can: * Manage your servers by writing code, not by running commands. (via Cookbooks) * Integrate tightly with your applications, databases, LDAP directories, and more. (via Libraries) * Easily configure applications that require knowledge about your entire infrastructure ("What systems are running my application?" "What is the current master database server?")

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.

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.

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

Puppet, the configuration management solution. The Puppet framework provides a means to describe IT infrastructure as policy, execute that policy to build services then audit and enforce ongoing changes to the policy. Puppet helps accomplish the goal of a hands-off, automated infrastructure.  The benefits of automated infrastructure go beyond policy-enforced consistency and auditing.  The impact of hardware failure and other disaster scenarios can be mitigated, as services can be quickly restored by Puppet. In conjunction with virtualizaton, the ability to reliably create new systems running consistent services can be leveraged to create autoscaling applications as well as test systems identical to production environments.

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

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.

Lift the curtain behind any modern web application and you will find at least a few proxy servers orchestrating the show.

For some scripting languages, like BeanShell, it's possible to access Android's Java API directly. To simplify things, ASE provides the AndroidFacade class. For other languages, like Python and Lua, the API is made available via JSON RPC calls to a proxy. Naturally this means that only the part of the API which has been wrapped by the AndroidFacade and AndroidProxy are available to cross-compiled interpreters like Python and Lua. Thankfully, both AndroidFacade and AndroidProxy are simple to extend.

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!

Cassandra is a hybrid non-relational database in the same class as Google's BigTable. It is more featureful than a key/value store like Dynomite, but supports fewer query types than a document store like MongoDB. Cassandra was started by Facebook and later transferred to the open-source community. It is an ideal runtime database for web-scale domains like social networks.

“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. Get on twitter. Let your voice be heard! You probably won’t have thousands of listeners right away, that’s OK - it takes time. But you can start today!

Google Website Optimizer seems a bit dirty - this looks like a cleaner way

Unfortunately I'm short on time at the moment (trying to launch a project this week) but I have to say, at least, a few words about the hacker and artist _why. At this moment, _why's online presence appears to be no more. All of his sites and code are gone. This includes, and is not limited to: * http://twitter.com/_why * http://github.com/why * http://whytheluckystiff.net/ * http://poignantguide.net/ * http://hackety.org/ * http://shoooes.net/ * http://hacketyhack.net/ * http://tryruby.hobix.com/ Two conjectures are common at the moment: His account(s) were hacked and sites taken down or he simply decided to delete his online presence. I personally believe that he did this deliberately and with some amount of forethought.

One of the things that's made _why unique amongst programmers is that he has worked in virtual anonymity. Some people knew his name but it was never a focus of his online persona (and, at least, never actively associated with him as a person - I've seen sites that purport to identify him, but they're generally incorrect, and fringe, at best). Even live, giving talks or performing music, he still went by his pseudonym.

Even live, giving talks or performing music, he still went by his pseudonym. Reading through the original discovery thread you can see a full range of emotion regarding his disappearance; Anger, confusion, and sadness. Personally, I feel a mixture of joy and amazement. _why, the code he's written, the persona he projected, and the art he produced has been a long-time admiration of mine. Some only see _why's code or writing (Why's Poignant Guide to Ruby, for example - which can still be purchased on Lulu). I tend to see _why more as an artist. He used a wide variety of mediums for his exploration: Written word, drawings, code, and even music.

_why, el famoso programador de Ruby y creador de libros maravillosos, borró su presencia online y desapareció. http://bit.ly/tvNJl [from http://twitter.com/dariuus/statuses/3430674235]

Why the Lucky Stiff has disappeared. I share John Resig's admiration for his whimsical approach and his pseudonymity, but find it hard to identify with deleting all your work.

"I've seen a few people ask why he opted to remove his code - why didn't he take his work seriously? (Especially since others have grown to depend upon it.) Looking at the cumulative work and art of _why it should become painfully obvious: The online presence of _why, and all the code, writing, music, and drawings that've been produced are a mere transitory portion of one person's life. He was constantly moving from project to project, blog to blog. Now he's truly moved on and we should feel joy in having gotten to know him, and his art, over the past couple years."

Monk is a glue framework for web development in Ruby. It’s truly modular by relying on the best tool for each job. It’s also pretty fast thanks to Rack and Sinatra.

Sinatra is a tiny and flexible tool. It can be used to write super simple web applications like an API or a fully-fledged, highly interactive website. As you develop more applications using Sinatra, you will start to find some patterns: You apply a similar structure to all of your projects (where to put your routes, whether to use classic or modular style, etc.) You also find some other common bits you need to set up a logger, configure reloading on development mode, and more. You need to hook up your persistence layer of choice. Wiring in your desired testing suite. It’s easy to see how time-consuming this can be when you want to start a new project with the minimum amount of work. That’s why we wrote a tool that could enable us to get started on a new project in no time. The result is a command line tool that lets you create a new project out of an existing skeleton. The default skeleton we ship does all the work for you, and you can just dive into your code.

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.

As the author of Beginning Ruby, I make money for every copy sold in print and electronic formats (as well as some miscellaneous income I’ll cover later). It’s not much money – but that wasn’t the motivation for writing the book. In this post I’m going to show you how it all works from my point of view including sales figures, pictures of my royalty statements, information about my advance, and similar gruesome stuff. There’s even a section at the end about how Apress pissed me off a bit (though I don’t regret the experience with them) and why I’m happy with you pirating my book if you so choose.

Nice summary of why you shouldn't give up your day job to write a technical book. The guy is wrong however in thinking he would make more money in giving the ebook away for free. It would be better to give a chapter away for free.

I started investigating how I might write native iPhone apps from a scripting language. Lua was on my radar already. It’s compact, expressive, fast enough, and was designed to be embedded. Took only about 20 minutes to get the Lua interpreter running on the iPhone. The real work was to bridge Lua and all the Objective-C/CocoaTouch classes. The bridge had to work in two directions: it would need to be able to create CocoaTouch objects and also be able to respond to callbacks as part of the familiar delegate/protocol model.

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.

"Most of today’s up and coming key-value stores are more than just simple key-value stores. You saw this when we looked at Tokyo Cabinet which, in addition to simple key-value capabilities, adds more sophisticated abilities, such as database-like tables. In this post we’ll look at Cassandra — a modern key-value store that continues this trend. Cassandra was originally developed by Facebook and released to open source last year. The Facebook team describes Cassandra as (Google) BigTable running on top of an Amazon Dynamo-like infrastructure."

Most of today's and up and coming key-value stores are more than just simple key-value stores. Cassandra is a modern key-value store that continues this trend.

Coined by Alex Russell in early 2006, the term Comet is an umbrella term for technologies which take advantage of persistent connections initiated by the client and kept open until data is available (long polling), or kept open indefinitely as the data is pushed to the client (streaming) in chunks. The immediate advantage of both techniques is that the client and server can communicate with minimal latency. For this reason, Comet is widely deployed in chat applications (Facebook, Google, Meebo, etc), and is also commonly used as a firehose delivery mechanism.

The next time you’re thinking about engaging in a technical discussion, run through these questions before you hit the “post” button: 1. Are you responding to facts? With facts? 2. Have you read any primary source materials on the issue you’re discussing? 3. Do you have any first-hand experience with the technologies or ideas involved? 4. Do you have any first-hand experience with those technologies operating at the scale being discussed? 5. Have you contacted the individuals involved in the discussion for further information before making assumptions about their findings? 6. Are you falsely comparing technologies or ideas as if there was a zero-sum competition between them? 7. Are you addressing your peers with respect, courtesy, and humility? 8. Are you sure that what you’re posting is the best way to promote your self, product, project, or idea? Does it demonstrate you at your best?

Don’t waste your life screaming into the void. Make things, measure them, have reasonable and respectful conversations about them, improve them, and teach others how to do the same.

"...why is something you can measure controversial? Are we not engineers?"

Sprockets is a Ruby library that preprocesses and concatenates JavaScript source files. It takes any number of source files and preprocesses them line-by-line in order to build a single concatenation. Specially formatted lines act as directives to the Sprockets preprocessor, telling it to require the contents of another file or library first or to provide a set of asset files (such as images or stylesheets) to the document root. Sprockets attempts to fulfill required dependencies by searching a set of directories called the load path.

BERT and BERT-RPC are an attempt to specify a flexible binary serialization and RPC protocol that are compatible with the philosophies of dynamic languages such as Ruby, Python, PERL, JavaScript, Erlang, Lua, etc. BERT aims to be as simple as possible while maintaining support for the advanced data types we have come to know and love. BERT-RPC is designed to work seamlessly within a dynamic/agile development workflow. The BERT-RPC philosophy is to eliminate extraneous type checking, IDL specification, and code generation. This frees the developer to actually get things done.

If you're considering doing large scale analysis of structured data (access logs, for example), there are dozens of enterprise-level solutions ranging from specialized streaming databases, to the more mundane data warehousing solutions with star topologies and column store semantics. Google, facing the same problem, developed a system called Sawzall, which leverages their existing Map-Reduce clusters for large scale parallel data analysis by adding a DSL for easy manipulation of data.

Map/Reduce Toolkit by NY Times engineers is a great example of a Ruby DSL on top of the Hadoop Streaming interface.

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.

"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. I suspect that many of you have installed a Ruby 1.9 and that it lingers somewhere on your harddrive without much use. 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. ;)

"This results in an increase from 500 requests/sec to 7000 requests/sec when using Sinatra+Thin+Epoll+Threads. That is pretty ill." -- Joe Damato

On top of all that, this patch helps with Ruby’s green threads, too. If the epoll_wait causes a Ruby event to fire and that event creates a Ruby thread, that Ruby thread gets an entire copy of the existing stack. Each time that thread is switched into and out of, that thread stack has to be memcpy’d into and out of place. Reducing those memcpys by ~800,000 bytes is a HUGE performance win. Want to learn more about threading implementations? Check out my threading models post: here. Fixing this turned out to be pretty simple. A six (6!!) line patch: * Speeds up GC by 2-3x because of the huge decrease in stack frame size. * Fixes an open bug in EventMachine where using threads with Epoll causes lots of slowness. The reason is that each thread will inherit an ~800,000 byte stack that gets copied in and out every context switch. * This results in an increase from 500 requests/sec to 7000 requests/sec when using Sinatra+Thin+Epoll+Threads. That is pretty ill.

l in all, a productive debugging session lasting about an hour. The result was a simple patch, with 2 big performance improvements.

Apple's iPhone has taken the nation by storm. An alleged half million moved from the shelves into people’s pockets in the first weekend it went on sale. Safari, the iPhone's native browser, claims to bring full featured browsing to the mobile device. 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. Add up all these custom tweaks and you should have the tools you need to take your web site mobile. For a primer on Ruby on Rails, take a look at the Related Resources connected to this article.

Migrations bother me. On one hand, migrations are the best solution we have for the problem of versioning databases. The scope of that problem includes merging schema changes from different developers, applying schema changes to production data, and creating a DRY representation of the schema. But even though migrations is the best solution we have, it still isn’t a very good one.

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.

There is basically no way to avoid writing software that leaks memory. It will happen, you just have to make it leak as little as possible. I still remember the massive effort that Tom Preston-Werner went through to get a relatively simple program like God.rb to not leak memory… and it still leaks memory!": 2008-11-20: kd.to_tumblr

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."

This sentence from the article says much: "In my experience, this style of coding tends to reduce the size of a codebase by an order of magnitude, while improving readability." Example from article: "...do not have to code defensively, using a slew of factories, patterns,...you can build a minimal solution and evolve it."

"Many people are looking for the "next big language." The next big language is already here, but it isn't a single language. It is the collection of ideas above (plus probably some I missed) as manifested in Java.next. -- Does the transition to Java.next deserve the name "big"? Absolutely. In my experience, the move from Java to Java.next is every bit as big as the previous tectonic shifts in the industry, both in learning curve and in productivity advantages once you make the transition."
