Usage - GitHub
"Jekyll at its core is a text transformation engine. The concept behind the system is this: you give it text written in your favorite markup language, be that Markdown, Textile, or just plain HTML, and it churns that through a layout or series of layout files. Throughout that process you can tweak how you want the site URLs to look, what data gets displayed on the layout and more. This is all done through strictly editing files, and the web interface is the final product."

"Grit gives you object oriented read/write access to Git repositories via Ruby. The main goals are stability and performance.

This choice, however, is transparent to end users, and you need not know which method is being used."

"In the social sciences, it is useful to understand the relative similarities of concepts that are embedded in a particular text (from a particular group or a particular person). For example, in trying to estimate conservative bias in FoxNews, one might estimate its tendency to associate conservative concepts (conservative, republican) and good concepts (good, positive, etc.), compared to conservative and bad concepts. The output would indicate conservative favoritism. This comparison could be further refined by taking into account important "baseline" information about the valences associated with liberal, namely liberal and good in comparison to liberal and bad.…"

Ruby Gem Management with RVM and Bundler
"When I started learning Ruby, managing gems was a huge problem to the point I would make fun of it. Now I use RVM which helps you install multiple versions of ruby on one computer. Not only does it do that, but it makes gem management a breeze as well! Beyond RVM, Rails 3 provides us with bundler, which allows you to install gems based on a list of dependancies automatically. Very slick.

Here I will outline how to install and configure RVM as well as manage your gems with RVM and the Rails 3 bundler."

What Pythonistas Think of Ruby | Free PeepCode Blog
"The main attraction (and last presentation) was from my friend Gary Bernhardt1. Gary spent a few months contracting on a Rails project for four hours in the morning and a Django project for four hours in the afternoon. So when he speaks of either, it’s not in ignorance.

At the end, I couldn’t find a single criticism of Ruby that I disagreed with. I did pick up a new appreciation for unique features of the Ruby language that I previously took for granted."

Intridea Blog: The Future's Pretty Cool, or Why I Love Ruby
"For me, being a part of the Ruby community feels like getting a sneak peek at where software development is going six months to two years from now. That’s not to say it’s all rainbows and daisies…the constantly changing landscape requires a real passionate dedication to keep up or you’ll quickly fall behind, and not all technologies are meant to immediately be deployed to massive-scale production environments (restraint is a skill a good Rubyist must learn and exercise on a regular basis). But I love Ruby because I feel confident that I will be made aware of trends in software development long before I would otherwise be expected to understand them."

Heroku | Experimental Node.js Support
"Node.js is evented I/O for JavaScript, built on top of the blazingly fast V8 engine. It makes handling event-driven I/O incredibly simple, and aligns perfectly with our maniacal focus on simplicity and developer productivity. The Ruby community has quickly adopted node, and with great reason. Complimenting existing apps with node.js for components that require real-time event handling or massive concurrency is both easy and elegant – in part thanks to the availability of frameworks such as express."

apotonick's active_helper at master - GitHub
"Helpers suck. They’ve always sucked, and they will suck on if we keep them in modules.

ActiveHelper is an attempt to pack helpers into classes. This brings us a few benefits

inheritance helpers can be derived other helpers
delegation helpers are no longer mixed into a target- the targets use the helper, where the new
methods are delegated to the helper instances
proper encapsulation helpers don’t rely blindly on instance variables – a helper defines its needs, the target has to provide readers
interfaces a helper clearly provides methods and might use additional helpers
Note that ActiveHelper is a generic helper framework. Not coupled to anything like Rails or Merb. Not providing any concrete helpers. Feel free to use clean helpers in any framework (including Rails and friends)!"

Patch Engineering - RakeServer is a client-server Rake architecture for fast task invocation
"Enter RakeServer, a tool Cedric and I hacked up this week. The idea here is to run Rake tasks using a client-server architecture, with a long-running server that responds to requests from clients to invoke tasks. The crucial feature of RakeServer is that it can also invoke tasks greedily when the server first starts — in particular the :environment task, which loads the Rails environment. That way, when the client invokes Rails-dependent tasks, the server is able to respond immediately without waiting all that time for the environment to load."

Apotomo Cookbook » Blog Archive » Onfire brings bubbling events to your Ruby objects
"In the current refactoring of Apotomo I finally extracted the bubbling event library into a separate ruby gem Onfire.

Bubbling events is, in contrast to Ruby’s own Observable module, focused on observing events triggered by business objects, not watching the objects themselves.

In addition, a triggered event will bubble up the tree branch and subsequently inform all ancestors- you get automatic organic event filtering.

Complete instructions are on the github page."

Redis: Data Cheeseburgers - GIANT ROBOTS SMASHING INTO OTHER GIANT ROBOTS

It’s not exactly a key value store, it’s definitely not a relational or document-oriented database. The biggest selling point of Redis is that usually as programmers we have to bend our data into a table or document to save it, but with Redis we can persist data as we conceptually visualize it.

For lazy evaluation, the facilities are similar to those provided by R5 Scheme.

The only way for RBP to remain current and relevant is to continue these discussions, using its content as a jumping off point for fresh ideas."

fingernails in oatmeal, Metaprogramming: Ruby vs. Javascript
"To be honest, there’s not much to say about the Javascript example because it is so simple. We avoid the whole metaclass business because Javascript uses prototypal inheritance. This means that Javascript does not distinguish between classes/prototypes and instances and, therefore, we can add our desired behavior directly to the instance. We use the exact same technique for adding a method to the prototype, but this time we simply add the function directly to the instance. Again, this function is a closure. And again, this function has access to the instance’s state using this.…
Closures are so ingrained in the language’s design that metaprogramming seems to happen without even trying. This little exercise has left me very excited about the potential of Javascript not only as a great language for the web, but also as a powerful server-side language. You should be excited too."

Introducing Resque - GitHub
"It boils down to this: GitHub is a warzone. We are constantly overloaded and rely very, very heavily on our queue. If it's backed up, we need to know why. We need to know if we can fix it. We need workers to not get stuck and we need to know when they are stuck.

We need to see what the queue is doing. We need to see what jobs have failed. We need stats: how long are workers living, how many jobs are they processing, how many jobs have been processed total, how many errors have there been, are errors being repeated, did a deploy introduce a new one?

We need a background job system as serious as our web framework. I highly recommend DelayedJob to anyone whose site is not 50% background work.

But GitHub is 50% background work."

A Wealth Of Ruby Loops And Iterators
"I classify looping and iterating in Ruby into two distinct buckets:

simple ways to loop/iterate – this is where we loop over elements and work with each element as we iterate over it, but we basically don’t need to retain any knowledge of what we did to a particular element once we move on to the next unless we explicitly decide to store some info (this is how the basic loops and iterators operate)
complex ways to loop/iterate – this is where in addition to iterating over elements we transform the elements we are iterating over in some way and retain this information when we complete the loop (this is how more complex iterator-style methods such as map, collect etc. work)"

"Languages can be split into two components, their syntax and their semantics. It’s your understanding of English syntax that tells you the stream of words "Sleep furiously green ideas colorless" is not a valid sentence. Semantics is deeper. Even if we rearrange the above sentence to be "Colorless green ideas sleep furiously", which is syntactically correct, it remains nonsensical on a semantic level. With Treetop, you’ll be dealing with languages that are much simpler than English, but these basic concepts apply. Your programs will need to address both the syntax and the semantics of the languages they interpret."

"Things to keep in mind.

No matter where you start, start with one simple test. One assertion, if you can manage it.
Write the code to make that test pass
Then refactor -- this part is critical, this is where the creative design is with a TDD process.
Then write the next test.
In Rails, you'll often start in the controller then realize that code needs to be written in the model (or vice-versa). Write a separate test for the model -- testing models from the controller makes it hard to test all the model logic.
It's okay to plan the tests in advance, but you should only work on one test at a time. (Sometimes I'll write the series of tests, then comment out all but one)"

Rubx
"Rubx, a.k.a. Ruby Boobie, is your personal Ruby interpreter in Twitter. Whether you are trying to test some Ruby code, play around with it or see what's capable of, Rubx is here for you.

Think of Rubx as IRB (the Interactive Ruby Shell), built-in on Twitter."

Oscar Del Ben: How to deploy your rails application with ruby 1.9
[Installing on Leopard Server seems even simpler, when I think about it]

"...And now you can start your server as usual with script/server. If you see any error, check the backtrace to see which plugin/gem is causing it and try to google about it, but hopefully your application will run smoothly from the first time."

Green is Good : software, science, etc
"Thanks to O'Reilly and the RailsConf organisers, we're introducing ActiveResearch, an extended satellite meeting at this year's RailsConf in Las Vegas. ActiveResearch is a great opportunity to meet and greet others working with Ruby and Rails in a scientific or technology discipline. We'll have some special guest speakers, a series of more informal lightning talks, finishing things up with a round table discussion of the state of the art, and some drinks and nibbles."

http://treetop.rubyforge.org/semantic_interpretation.html
"This is a parse tree whose nodes are instances of Treetop::Runtime::SyntaxNode. What if we could define methods on these node objects? We would then have an object-oriented program whose structure corresponded to the structure of our language. Treetop provides two techniques for doing just this."

Agile Ajax » Using Cucumber for Acceptance Testing » Pathfinder Development
"My experience so far, as I explore what Cucumber can do, has been largely positive. Where I was starting with Cucumber and only a vague idea of how the user interaction would play out, writing the scenarios at the Cucumber level felt very valuable and gave the development a clear path that I wouldn't have otherwise had. That said, there is extra code being written, and it's clearly possible to get really tangled in getting the step definitions right."

Ruby Polyglot: Talking with Erlang - igvita.com
"Turns out, Scott Fleckenstein and Tom Preston-Werner have already solved this problem for us, allowing bi-directional data exchange between Erlang and Ruby via Erlang Ports. As far as Erlang is concerned, this communication pattern is seen as direct communication with another Erlang process, which also means we can transparently invoke our Ruby interpreter whenever we need it! To get started, gem install erlectricity: Erlectricity allows a Ruby program to receive and respond to Erlang messages sent over the Erlang binary protocol."
