Rails: reset_session and Webrat Don't Play Nicely with One Another

All the Rails security guides say that you should call reset_session after the user logs in or logs out. This clears out the session and forces a new session ID to be created. It seems there have been a few Rails bugs related to reset_session over the years. In my login action, I call reset_session and then put a nice message in flash. When I actually use the website, I can see (via Firefox) that I'm getting a new session ID, and I can see my flash message. However, when I write tests for those two things, the flash message gets lost, and I don't get a new session ID in my cookies. It's almost as if the new session is being ignored, and the old session is being used. I submitted a bug to Webrat about this, but it turns out it's an issue in Rails. This issue is present in version 2.3.8. If this is affecting you, there's a workaround here . I implemented the workaround, and it worked like a charm :)

Ruby: Blooger

I needed some sample code for an interview, so I built a website called Blooger . It's a site (like Blogger) where people can go create a blog to blog about their booger stories. It even has functioning Atom feeds :) Here's the source code . I used Cucumber, RSpec, Webrat, and factory_girl to do behavior driven development. I used Authlogic for authentication. I used BlueCloth for Markdown support in order to format the blog posts. The README in the source has more details.

Books: Programming Scala

I just finished reading Programming Scala . In short, I really liked it. The first few chapters are breathtakingly fast. Some of the middle chapters are kind of slow, but are still worthwhile. Scala is a fairly large language (unlike, say, Scheme or C), and the book is a fairly dense 400 pages. I found it helpful to read slowly and take notes. As for Scala itself, I really like it! Scala is a nice mix of Java, C#, Erlang, Haskell, Ruby, and Smalltalk. You can treat it as a "better Java", or you can treat it as a more enterprise-friendly Haskell. Either way, it's exactly what I was looking for: a language with reasonable syntax, an ML type system, and a decent set of real world libraries. I know that the Haskell community is working hard in this direction as well. I think Scala stands a very good chance at being a work-friendly, programmer-friendly language. I'm a little afraid that its type system may be too large and too complex for a lot of programmers.

Personal: Looking for Work

I'm looking for a new job. As much as I've enjoyed my time at my current company, I'd like to move on to something new. I'd like to give Scala a shot, if possible. For the last year, I've been doing Ruby on Rails, and before that I was doing Python. I've been learning Scala in preparation of making the transition. I'm only looking at companies in San Francisco or the East Bay. I prefer behavior driven development and really clean code. I'm really bad at working on sloppy code bases with no tests and no documentation. I prefer Linux. I have a predilection toward startups. Here's my resume . Thanks!
