This release contains additional deprecation notices, security fixes and some minor performance improvements. All users of 1.2.3 are advised to upgrade.
Deprecation Notices
If you intend to upgrade to 2.0 you should run your tests to and fix any errors that are displayed. The warnings will become errors with the release of 2.0.
If you’re using RESTful routing, pay special attention to the changes to route generation and recognition. The previous use of the semicolon in URLs has been replaced with a regular /. For instance /person/1;edit has become /person/1/edit. This change was made as several libraries, including mongrel, mistakenly treated semi-colons as query string seperators and some browsers and http libraries misbehaved.
Your old ;-based URLs will be continued to be recognized, though. They’re just no longer generated.
Security Enhancements
1.2.4 fixes several potential security issues:
- Session fixation attacks are mitigated by removing support for URL-based sessions
- Changed the JSON encoding algorithms to avoid otential XSS issues when using ActiveRecord::Base#to_json
- Potential Security and performance problems with XmlSimple have been fixed by disabling certain dangerous options by default.
Upgrade with the standard gem install rails command. Rails 1.2.4 serves as a drop-in replacement for 1.2.3.

15:05 Erlang-like Method Definition in FlexMock » { | one, step, back | }Some fun with Erlang and FlexMock.
Erlang Function Defintions
Erlang defines functions by listing a set of possible argument lists and the body of the function to be executed for each argument list. For example, the factorial function might be defined in Erlang as:
factorial(0) -> 1;
factorial(N) -> N * fac(N-1).
If factorial is called with a 0 (zero) for an argument, the first argument list will be chosen and the value of the factorial function will be 1. Otherwise, the value returned will be calculated by a recursive call to factorial.
FlexMock and Erlang
While playing around with FlexMock the other day, I realized that it does parameter matching, much like Erlang, when deciding what mock method to call. So I started wondering if you could write Erlang-like function definitions in FlexMock.
Here’s the result.
mock = flexmock('fact')
mock.should_receive(:factorial).with(0).and_return(1)
mock.should_receive(:factorial).with(Integer).
and_return { |n| n * mock.factorial(n-1) }
Ok, that was fun. But let’s not start building entire systems using nothing but FlexMock.

Some folks have been asking me for the clear definition of the term Web 3.0.
- Web 3.0 is defined as the intercalation of user-driven cross-bulterized falwettons, when traized with sufficient lenterains over extend periods of reticurotation.
Or, more concisly
- A marketing semantic land-grab, full of sound and fury, signifying nothing.

Best Tech Videos is hosting a hand-held video of the keynote I gave at RailsConf EU. The majority of the talk was a live coding session, though, which is kinda hard to follow from the angle of this shot. But in case you don’t want to wait for the official O’Reilly copy, here’s something in the meanwhile.

- 说明iMacros
- 这是一款录制浏览器的操作的Firefox插件。类似产品有 Selenium 和 CoScripter 。关于插件CoScripter，网络上有这样的评论：”我已经测试了CoScripter。问题是，这个插件仅仅针对最简单的网络页面。。。认为iMacros已经明显地走在前面了。”。我以为插件Selenium是一款很好的录制浏览器的操作软件。

It used to be that going for a walk and taking your camera was called "going for a walk and taking your camera."
No longer. Apparently now it's called Photowalking. So,
to keep up with the cool kids, I will use the same name.
For the last two nights, I've been "photowalking" around my neighborhood. None of the photos I've taken have been "amazing" or "stunning" or "you've-gotta-see-this" quality, but I especially like this one of the trees silhouetted against the evening sky.
You can see the rest of the pictures at the following links:

Our community is our greatest asset, and thanks to every single one of you who’s helped out throughout our history.
add to del.icio.us. look up in del.icio.us. add to furlBehold, behold, Rails 2.0 is almost here. But before we can slap on the final stamp, we’re going to pass through a couple of trial release phases. The first is this preview release, which allows you to sample the goodies in their almost finished state.
We might change a few things or add something else, but by and large, this is how Rails 2.0 is going to look and feel. After this release have had a chance to be tried out, we’re going to move to a release candidate or two (or three, depending on how many we need). Then, the final release.
Before the release of 2.0, we’re also going to be putting out 1.2.4, which will include a variety of bug fixes and the last deprecation warnings to get you ready for upgrading an existing application to 2.0 standards.
Enough about process. Let me tell you a little bit about what’s new in Rails 2.0:
