These past few weeks have brought forward a few interesting developments in the Ruby database access layer. First, the guys at espace announced Neverblock: a Ruby 1.9 library which makes heavy use Fibers and non-blocking IO (RubyInside and InfoQ have the scoop). And shortly thereafter we saw the announcement of MySQLPlus (also a direct result of work around Neverblock): An enhanced MySQL database driver. With support for async operations and threaded database access. Nice! Asynchronous ...

We’ve been having a discussion inside Object Mentor World Design Headquarters about the meaning of the OCP for dynamic languages, like Ruby, with open classes. For example, in Ruby it’s normal to define a class or module, e.g., # foo.rb class Foo def method1 *args ... end end and later re-open the class and add (or redefine) methods, # foo2.rb class Foo def method2 *args ... end end Users of Foo see all the methods, ...

Whatever you write today will become legacy. Legacy code is often written by people who thought they got it nailed, and later realize that the application is legacy. Not because of the application itself, but because of changes in themselves. “What the hell was I thinking?” Code is always the same, it’s your perception of it that changes. Code goes from “Best Code Ever” to “Legacy”. You are in the “Best Code Ever” phase now, ...

Maybe I’m just being paranoid here, but I’m starting to get a little worried that RubyGems could be a nasty attack vector, given certain combinations of malice and stupidity. Six months ago, the Ape project picked up some collaborators with way more Ruby-savvy than I have, and in short order they moved it to RubyForge and made it into a Gem. Which means that anyone who uses RubyGems, i.e. every Ruby developer in the world, ...

The file manipulation routines in Ruby's stdlib are a bit of a mess. Operations are scattered among different classes - File, Dir, and FileUtils. Methods often aren't where you expect them - like File.directory? but not Dir.directory?. But worst of all, they aren't object-oriented. You'd want to make calls like f.size or f.directory?, but instead you're stuck with File.stat(f).size and File.directory?(f). Pow is a library that attempts to clean up this mess. The file portions ...

The Juggernaut plugin for Ruby on Rails aims to revolutionize your Rails app by letting the server initiate a connection and push data to the client. In other words your app can have a real time connection to the server with the advantage of instant updates. Although the obvious use of this is for chat, the most exciting prospect is collaborative cms and wikis.

Do you find yourself copying and pasting the same code from Rails application-to-application as new projects start? Our team has a handful of projects in development right now and we notice that some of these reusable components tend to get out of sync when we bounce between projects. So, we’re making an effort to spot these and are creating a handful of plugins so that we can keep them updated between projects. (I’m sure that ...

一般查看ruby gem 文档都会开一个gem server ，但多少有些不便，每次都要运行一个gem server 不说，浏览器本身也身兼数职，又要测试，又要收mail，又要停车，又要看文档，切换起来越来越不方便。索性写了一个ruby gem 文档浏览器 - Goo . 另一只龙。 主要功能就是查看gem 文档。除了查看文档，查看gem的代码也是了解gem必不可少的过程，所以也集成了在Finder和TextMate里打开gem的功能。虽然我在shell里也加了自动匹配打开gem的脚本，不过看着文档，一点就看到代码，还是比在Terminal和Safari之间切来切去要方便一些。 功能不多，源代码也非常之少，LOC只有两百多行，从决定动手到写完花了不到两天的时间。Cocao/Object-C也是开发效率相当高的组合了。源码分享在github。 支持Mac OS X 10.5，或许rubygems的版本也需要>1.2.0。目前版本0.2，可以到这里下载。 © Robin Lu for 石锅拌饭, 2008. | 本文链接 | 快来留言 | Add to del.icio.us Post tags: freeware, gem, hack, mac, ruby

Some of them have been well-covered elsewhere. All I assert is that after I read ...
