Rewriting the Ruby parser –At Shopify, we have spent the last year writing a new Ruby parser, which we’ve called YARP (Yet Another Ruby Parser). As of the date of this post, YARP can parse a semantically equivalent syntax tree to Ruby 3.3 on every Ruby file in Shopify’s main codebase, GitHub’s main codebase, CRuby, and the 100 most popular gems downloaded from rubygems.org. We recently got approval to merge this work into CRuby, and are very excited to share our work with the community. This post will take you through the motivations behind this work, the way it was developed, and the path forward.

GitHub – gregmolnar/prepper: Prepper is a simple server provisioning tool, built on top of SSHKit. You can use it to script your server build process. –This seems like a very nice simple tool to solve a common problem. My only confusion is that there are a bunch of similar tools to do the same thing. Each has its own DSL, written in ruby or some other language, has its own conceptual steucture, and its own bugs. It’s enough to make me decide to just keep doing it by hand. Heres what the author says: “ Prepper is a simple server provisioning tool, built on top of SSHKit. You can use it to script your server build process. – GitHub – gregmolnar/prepper: Prepper is a simple server provisioning tool…”

An Introduction to Ractors in Ruby | AppSignal Blog –I read and heard about Ractors in ruby. This article demystifies them. My evaluation: Ractors are a safer alternative to Threads.

Welcome to Bashly | Bashly – Bash CLI Framework –Bashly is a command line application (written in Ruby) that lets you generate feature-rich bash command line tools.

Why Use MongoDB with Ruby –I haven’t read this yet, but the topic is of great interest: “Before discovering Ruby and Ruby on Rails I was a .NET developer. At that time I’d make ad-hoc changes to my development database, export my table/function/stored procedure/view definitions to text files and check them into source control with any code changes. Using diff functionality I’d compare the schema changes that the DBAs needed to apply to production and we’d script that out separately.”

It has some similarities with things like JSFiddle or CodePen, but can run Ruby (as well as Python, C and C++). It can even act interactively and accept user input (such as with gets). You can then take these sandboxes and use them on your own pages/blog posts, etc.

Yep, that's right. A Ruby class that inherets from nothing. It's so simple that it hides in plain sight. Loved by those who've mastered Rails, Plain Old Ruby Objects, or "POROs" as some like to call them, are a hidden weapon against complexity. Here's what I mean. Examine this 'simple' model:

But I digress: objects > functions. At least in the context of getting stuff done in Ruby. This pretty much applies to most of the rest of the points in this post, so just keep that in the back of your brain.

Sinatra applications are often a single file that contain just enough to get the job done. The framework is best suited for smaller web applications, but if a large web app requires an API or web interface for some secondary functionality, then Sinatra is ideal.

Jorge Coca | [HOW-TO] Build a Rails gem with Bundler – Gumby Framework:

Since I’m building a new Rails website, and I wanted to use Gumby as a part of my Gemfile, and I couldn’t find a gem with the newest version of the framework, I decided to write my first Rails gem and publish it to the community.

I first came across Sandy Metz in this video:

[vimeo 12350535 w=500 h=281]

2009 – Sandi Metz – SOLID Object-Oriented Design from Gotham Ruby Conference on Vimeo.

If you are interested in Object Oriented design you will enjoy this. She is a wonderful speaker, and fun to listen to. Even if you don’t agree with (or understand) some of the concepts, I promise that you will enjoy listening to it. Since then Sandy has come out with a wonderful new book which I highly recommend: ...

I’ve been doing some more coding these days in Ruby.

I’ve had great success and fun (especially when debugging) using RadRails, which is an Eclipse based IDE for Ruby and Rails. It’s quite nice.

With introduction of RVM, bundler, and so on, I’ve gotten a feeling that RadRails maybe too much. It seems to get contexts confused and create more hassles. I am not sure yet, but it’s caused me to go back and use TextMate, which I’ve always had in an honored spot in my toolset.

Poking aroun...

A random, highly specific and geeky tip:

If you’ve used Capistrano before, you’re familiar with the large error logs. Finding errors is, well, a hassle. You’ve got a whole slew of text, some just saying what command it’s going to execute next, sometimes errors, sometimes just output from Bundler or whatever it’s running. (from Rails Tip #8: Capistrano Colors)

Just follow the link to Rails Tip #8: Capistrano Colors) and your Cap life will be a little better.

Just a quick hit: Ruby on Rails tips that will male you a better programmer.

Just a quick read of this post showed me several great gems that I want to try right away! If you’re a Rails programmer this is going to be of great interest: Rails 3: Fully Loaded

ActiveAdmin is particular looks like an excellent new way to generate a whole suite of reasonable views and controllers to create, read, update and delete information in Rails3 applications. ActiveAdmin is customized with a DSL so that you have a prayer of getting what you want without hacking the hell out of the logic that is built in. I will definitely try it.

How to build authentication into Rails applications? Well, at least at RailsConf 2011, the buzz was around a new Authentication gem called Devise.

I played with it a little (here in the airport) at it seems quite nice and straightforward. Check it out if you were looking for something like that.

railsconf

Another tidbit I came across at RailsConf is Hobo. I haven’t tried it myself but did just go through the screencast and tutorial. I think it’s worth a closer look.

“Hobo is a plugin for Ruby on Rails that brings a number of extensions—some small some large—to Rails application development. The common theme to these extensions is rapid development.

Like Rails itself, Hobo encapsulates a number of opinions about web application development. The opinion that is most central to Hobo is this: we have found that there is a great deal of similarity from one web application to the next. Much more similarity in fact, than is supported by today’s frameworks. We w...

Why doesn’t every one love Rails? I am surprised when I run into someone (Pat?) who’s not so sure about Rails. Usually it’s about scalability.

When I am designing or building a system and am questioned about whether writing it in Ruby or Rails is a good idea. Or if someone asks me my opinion or for advice about whether it makes sense that his or her developers are recommending Rails for a big site.

What I believe is that scalability has to do with the overall system architecture — caching, queueing, horizontal scalability and so on. It does not have to do with the programming language. (What the LivingSocial guy said about this wasn’t quite ...

Over the last several months I’ve been following a series of blog postings by Jamis Buckon the esoteric and quirky topic of writing programs to design mazes.

Today in his final installment he summarized the project:

Just came across this handy-dandy tool to run tests for Ruby and Rails, and produce much nicer and readable traces so you have a prayer to sort out what is going on when stuff fails.

Test::Unit Reporter — A new look and feel for Test::Unit output

TURN is a new way to view Test::Unit results. With longer running tests, it can be very frustrating to see a failure (….F…) and then have to wait till all the tests finish before you can see what the exact failure was. TURN displays each test on a separate line with failures being displayed immediately instead of at the end of the tests.

I went to RubyConf and heard a detailed presentation on a new possible feature of possible Ruby 2.0 called ‘Refinements’. I have to admit that I didn’t fully grasp how the feature really would be used. Here’s a nice and quite techical article about it: Ruby 2.0 Refinements in Practice from Katz Got Your Tongue?: "The first thing you need to understand is that the purpose of refinements in Ruby 2.0 is to make monkey-patching safer. Specifically, the goal is to make it possible to extend core classes, but to limit the effect of those extensions to a particular area of code."

RubyConf 2010 was excellent. It was my first and probably not my last. Some general thoughts and then a master list of links (the real meat.)

Unlike most all ‘business’ type conferences and talks I have gone to, the RubyConf style of presentation (and perhaps the Rails or Ruby community — I don’t know where it stops) is beautifully minimalist. Very few words on slides, large and impactful photographs. Is it because no one uses PowerPoint and few even use Keynote? I don’t know. But there were no text heavy, bullet heavy word slides. And also, lots and lots of code (that part is definitely a geek thing.)

Here is a loosely organized set of links to the things that hit me most at RubyConf this...

The problem with conferences is knowing what session to go to, right? Check out this talk called “ZOMG WHY IS MY CODE SO SLOW? Aaron Patterson. It’s really excellent. It has many specific pointers that I will be able to use as soon as I get back.

(Yes, in case you wonder: ZOMG)

Odd thing happened in a talk at RubyConf. Speaker asks all attendees who are using Windows to raise their hands. Looked to me like about 3% of folks here are on Windows. Now its a very biased audience but still an interesting number!

This looks like a really nice and detailed tutorial on how to use Twitter in Rails. Check it out! p.s. if you don’t know what the previous sentence means, don’t worry about it. You must not really be geeky.

I get asked from time to time to recommend ruby, rails, and other developers in the Boston area, either for full time or part time gigs. I’m developing a list of good local job resources – started so far with the help of pal Brian D:

Check out this interesting case study of how one awful memory leak was tracked down and killed: “It’s every developer’s worse nightmare. You’ve bet the farm on a development framework, spent thousands of person-hours developing your application and then find a memory leak. Worse yet, you’ve got a memory leak in an interpreted scripting environment where you have little to no control over how memory is allocated and managed at runtime.” (from Tracking a memory leak in Rails)

A recent post talked about creating a “Domain Specific Language” for image processing of ballots. I’ve made a lot of progress on that project and wanted to give an update.

“So yet another way you can help Ruby and Rails Activism is by attending (supporting) a conference. Below you’ll find conferences coming up in the next 6 months. If you think I’ve missed one, or if the information is incorrect, please post a comment.” (from Riding Rails)

If you look at the list of conferences and meetings, all looking interesting, there’s nothing anywhere near Boston. Hey, whatup?

I tried the first two, but the third looks cool too. I liked Facebox the best. Your mileage may/will vary.

Sites that have to support a huge amount of traffic tend to want to be static html. No matter how fast PHP or perl is, in the end, static pages win. So tools pop up to allow you to generate a templated site, but generate it into static html to kind of have your cake and eat it too. Webgen is one of those static web site generators. Here’s what it does:

“When webgen is run it combines the template with each of the page files and generates the HTML output files. During this process special tags are substituted so that, for example, a menu is generated. Actually, this website was generated with webgen and, for example, the menu that you can see was created dynamically. For more information look at the documentation!” (from Webgen)

Over the last 2 weeks I’ve been actually able to carve out some quality time to get my head around Ruby and Ruby on Rails.

My play project is something called myscum.org, which is a lightweight scrum tracking tool. Basically it’s modeled after what I’ve been using for BlogBridge, working with Aleksey. So a pretty simple case, makes a decent play project.

But of course, that’s how BlogBridge started. A decent play project…

I’m an on and off [tag]Ruby[/tag] developer, and recently I’ve been trying to decide whether I should use Eclipse for Ruby development or whether TextMate (I am on a Mac) is better. Why even think of [tag]Eclipse[/tag]? Simply that I know it well and it’s very rich for developing Java. It’s also cross platform. From my investigation though, Ruby support in Eclipse is still immature.

On Mac, TextMate is the hero of Ruby developers. But given that Ruby doesn’t have a debugger and nirvana to Ruby developers is the interactive ruby shell, IRB, I’m not convinced yet.

Here’s a good article on maximizing TextMate for Ruby: ...

This is a topic that I’ve gotten somewhat interested in. If you search for Ruby Domain Specific Languages in google, you will find a ton of hits. Here are two that I particularly liked:

If you are a Ruby On Rails developer you might want to check out this post from dzone.com: latest front page: ** "Itâ_Ts not particularly hard to deploy your app in a subdirectory, but Iâ_Tve found that figuring out how to can be. So, I decided to put together this short little write-up."

I was discussing with a friend yesterday, really, what’s the difference between a scripting language and a ‘real’ language? Is Java a ‘real’ language? After all it does run on top of an interpreter (the JVM.) But what’s an interpreter anyway? Is the only ‘real’ language C++? Even C# is questionable?

Ah I think that’s all old think. I do think there’s a qualitative difference between a Ruby and a Java, but it’s not about scripting versus real. It’s about something else…. and by the way, what happens when Ruby is run on top of the JVM?

I’ve been learning Ruby and Rails in my copious spare time. I found this post instructive on how to write idiomatic Ruby instread of Ruby as C: Idiomatic Ruby.

I’m getting a little fascinated with Ruby and Rails so I’ve been getting acquainted with it. Just want to share a handy link with detailed instructions on how to build and configure all that stuff on a Mac. Handy if you are in the .01% of the world who cares 🙂

Heard a lot about Ruby? Ruby on Rails? Wonder what the heck it is? Here’s a good intro.

“This is not yet another “Ruby is better than Java” article. Nor is it intended to bash Java or Java programmers. Rather, it is an attempt to aid Java programmers who are investigating Ruby by helping them quickly get over the “Writing Java in Ruby” syndrome and to discover the Ruby Way.” (from “10 Things Every Java Programmer Should Know about Ruby”)
