1. Sneaker98 at fireflyfans.net put up mp3s of all the music from Firefly. They're recorded straight from the show, so unfortunately the music isn't separate from dialogue and such, but after listening to random clips, it's still great. Downloading with Bittorrent now. Thanks Sneaker98.

3. I need some spice in my programming life. After reading Sam Ruby's most recent post about Ruby on Rails, I think it's time for me to learn Rails. It'll be a good exercise for me to gain some intimate knowledge of Ruby as well.

When static typing gets in the way

I want to do the following in Java:

SuperClass s = Class.forName("fully-qualified-class").newInstance();
s.process(foo, bar);


I know that given what "fully-qualified-class" is I can call process on s, but Java's static typing thinks I can't, so it won't let me.

Update: I'd like to correct myself a little: Ultimately, the real reason that you can't call process on s is because on the base class the process method is protected, whereas on the subclasses I need to call it on it's public. So, you could argue that this is really a case where access controls (not static typing) are getting in the way, or a case where the access controls on this class hierarchy weren't designed well enough. I lumped this in with static typing because in a normal message-passing style of OO this wouldn't be an issue, since the message would be passed and the object would either accept or reject it.

2. CHIP: Code Highlighting in PHP:

   CHIP is a simple source code highlighter designed to be used either on web-servers or from the command line. It takes C, C++, Java, Lisp, Python, PHP, HTML, or JavaScript code, and outputs an XHTML version of that code, with appropriate highlighting.
