Why MacRuby Matters (Present & Future) | Programming Zen
Over the years the inadequacy of Ruby’s main implementation has led to the creation of several alternatives. The greatest common divisor between these is an attempt to improve the performance of Ruby, both in terms of time and space. But every Ruby implementation has another, deeper reason for being. For example, Ruby 1.9.1 is a refactoring of the language that provides the chance to incorporate s
A close look at three Rails 2.1 bugs | Programming Zen
Ruby on Rails 2.1 has been out for six weeks now. Let’s take a closer look at three database related bugs that affect this release. 1. SQLite’s db creation generates false warnings This is an innocuous bug, and if you work with SQLite I’m sure that you encountered and safely ignored it. When you create a Rails application, the default adapter in use is sqlite3, unless you specify otherwise with th

MagLev handles trees like a monkey | Programming Zen
Over the past couple of nights, I tried out MagLev on my Mac laptop (Mac OS X Leopard, 2.2GHz, 2GB Ram). While the shootout will provide us with a detailed comparison between MagLev and the other major Ruby implementations (on many tests) I thought I’d share my first impressions. MagLev is going to be a fast implementation of Ruby. How many times faster? Well, it depends on the test, and I don’t h
Rails is the best thing that ever happened to Python | Programming Zen
Rails has been a blessing and a curse for the Ruby community. It brought sudden popularity to the language with all the consequences, good and bad, that usually result from exponential growth. On one hand, it gave many developers the chance to appreciate the design of the Ruby language based on its own merit. On the other hand though, it’s been a cash cow that’s changed the community forever by at
RailsConf, Arc, Apple and other Zenbits | Programming Zen
Zenbits are posts which include a variety of interesting subjects that I’d like to talk about briefly, without writing a post for each of them. Ruby and Rails Videos Blip.TV is now hosting the videos of RailsConf 2007. The audio and video quality is very good even though no slides are shown (but you can always google them). While on the subject, you can also watch the videos for RubyConf 2007 (inc
Ramaze: a Ruby framework that will amaze | Programming Zen
Lately the Ruby community has experienced a surge of new web frameworks. Most of them are respectable and promising open source projects created by people who tried to create lightweight but valid alternatives to Rails. Do I think that they will rise to fame just like Rails did? Of course not, but they are not hopeless copycats either, because they express a different “software opinion” while main
A preliminary review of three Cocoa and Objective-C related books | Programming Zen
A preliminary review of three Cocoa and Objective-C related books As announced before, I got interested in Mac development, bought a bunch of books and spent a few nights reading and coding. Here are my first impressions on those books which thus far I’ve picked up. I only had time to read 3 chapters from Stephen Kochan’s book and I must say that I’m not impressed! The pace is extremely slow and e
On Ruby and Rails Criticism | Programming Zen
If there is one thing that politics teaches us, it is that humans have different views on how to approach and solve problems. In politics no party has the solution for all problems that affect society. Some ideas are objectively more promising than others and have a track record of being implemented with success, greatly benefiting the general population. But typically it’s not possible to state t
Acts As Suggest plugin | Programming Zen
When searching for the word “honnolullu”, Google will promptly suggest “Did you mean: honolulu”. This feature is quite useful because it drastically improves usability. The lack of this exact function makes Wikipedia a pain in the neck as far as searching goes. So much so that I, and I suspect most people, just google for “wikipedia searched_term”. Hence, I decided to create a small plugin. The ac
Ruby Implementations Shootout: Ruby vs Yarv vs JRuby vs Gardens Point Ruby .NET vs Rubinius vs Cardinal | Programming Zen
Ruby Implementations Shootout: Ruby vs Yarv vs JRuby vs Gardens Point Ruby .NET vs Rubinius vs Cardinal Many brilliant developers are working on improving the current implementation of Ruby and on creating alternatives. I was curious about their current respective speeds, so I installed and ran some benchmarks for the most popular implementations. In this article, I’m sharing the results for the c
Top 10 Ruby on Rails performance tips
The performance of Ruby on Rails is influenced by many factors, particularly the configuration of your deployment server(s). However the application code can make a big difference and determine whether your site is slow or highly responsive. This short article is about some of the tips and best coding practices to improve performances in Rails only, and won’t attempt to cover the server configurat
