Raptor: A Forthcoming Ruby Web Server for Faster App Deployment

By Peter Cooper / October 21, 2014

Raptor bills itself as a new Ruby “app server” and it claims to blow everything else out of the water performance-wise (by between 2-4x!) whether that’s Unicorn, Puma, Passenger, or even TorqueBox on JRuby. The bad news for now is there’s no source or repo yet and only a handful of people (including me) have been given a sneak peek, although a public beta is promised on November 25th.

The history of Ruby webapp deployment

The deployment of Ruby (and therefore Rails) webapps was a painful mess for years, a state I lamented 7 years ago in No True ‘mod_ruby’ is Damaging Ruby’s Viability on the Web. Read More

Ruby’s Unary Operators and How to Redefine Their Functionality

1 Comment

By Peter Cooper / October 16, 2014

In math, a unary operation is an operation with a single input. In Ruby, a unary operator is an operator which only takes a single ‘argument’ in the form of a receiver. For example, the – on -5 or ! on !true.

In contrast, a binary operator, such as in 2 + 3, deals with two arguments. Here, 2 and 3 (which become one receiver and one argument in a method call to +).

Ruby only has a handful of unary operators, and while it’s common to redefine binary operators like + or [] to give your objects some added syntactic sugar, unary operators are less commonly redefined. Read More

Does the GIL Make Your Ruby Code Thread-Safe?

7 Comments

By Jesse Storimer / June 19, 2013

This is a guest post by Jesse Storimer. He teaches the Unix fu workshop, an online class for Ruby developers looking to do some awesome systems hacking in Ruby and boost their confidence when it comes to their server stack. Spots are limited, so check it out the class while there’s still room. He’s also the esteemed author of Working with Unix Processes, Working with TCP Sockets and Working with Ruby Threads.

There are some misconceptions in the Ruby community about this question surrounding MRI’s GIL. If you only take one thing away from this article today, let it be this: The GIL does not make your Ruby code thread-safe. Read More

Welcome to this week’s roundup of Ruby news, articles, videos, and more, cobbled together from my e-mail newsletter, Ruby Weekly. Sorry these roundups have been missing for a couple of months, I’ve been focusing very heavily on the e-mail newsletters which are continuing to grow like crazy! :-) I hope to get back into blogging more soon.

Matz on Ruby 2.0
Matz spoke about Ruby 2.0 (‘the happiest release ever’) for 30 minutes at the Heroku Waza event a week ago and the video is already available to watch. He stresses that “Ruby 1.8 will die soon” and encourages everyone to upgrade. Read More

A Simple Tour of the Ruby MRI Source Code with Pat Shaughnessy

5 Comments

By Peter Cooper / December 3, 2012

I’m not in Ruby core or, well, even a confident C coder anymore, but I’ve long enjoyed digging in the Ruby MRI source code to understand weird behavior and to pick up stuff for my Ruby course.

Pat Shaughnessy is also a fan of digging around in Ruby’s internals and has written some great posts like How Ruby Executes Your Code, Objects, Classes and Modules, and Exploring Ruby’s Regular Expression Algorithm.

When Pat released his Ruby Under a Microscope book, I knew it would be right up my street! He digs into how objects are represented internally, why MRI, Rubinius and JRuby act in certain ways and, of course, “lots more.”

I invited Pat to take a very high level cruise through the MRI codebase with me so we could share that knowledge with Ruby programmers who haven’t dared take a look ‘under the hood’ and to show it’s not as scary or pointless as it may seem. Read More

The Split is Not Enough: Unicode Whitespace Shenigans for Rubyists

8 Comments

By Peter Cooper / November 26, 2012

That code is legal Ruby! If you ran it, you’d see 8. How? There’s a tale to tell..

The String with the Golden Space

I was on IRC in #nwrug enjoying festive cheer with fellow Northern Rubyists when ysr23 presented a curious problem.

He was using a Twitter library that returned a tweet, “@twellyme film”, in a string called reply. The problem was that despite calling reply.split, the string refused to split on whitespace. Yet if he did “@twellyme film”.split in IRB, that was fine.

International man of mystery Will Jessop suggested checking $; (it’s a special global variable that defines the default separator for String#split). Read More
