Multiple Symfony versions in the same environment
I've been using this trick from symfonynerds to run multiple Symfony versions in the same environments. I can now work on projects built on Symfony 1.0, 1.1, and 1.2 simultaneously in the same environment (Ubuntu 8.10).
So now, when I want to create a Symfony 1.0 project, I would just execute "$ symfony10 init-project myproject". And then in the project I would use "$ ./symfony cc" instead of "$ symfony cc".
It worths mentioning that I think this trick is good for development environment but "svn:externals" trick or Symfony freeze are better for production/deployment as each project will have their own copy of Symfony Framework.
How to handle dot in Symfony URL
This problem with dot in Symfony URL is a common issue faced by developers. I've seen people asking about it few times in the symfony-users mailing list, and in fact I have asked about it once. Here's one recent thread about it in the mailing list.
Why I like Symfony Framework
I have been doing Java programming for quite a few years. Java is where I got my OOP lessons from and it just makes sense to me, from the multi-threading model, interfaces, abstract classes, encapsulation, to the bean.
I became known as Java man, because 1) I was born in Java island, 2) I program Java, 3) I can speak Javanese, and 4) even though unrelated, I also do Javascript.
